All commercial bathroom accessibility modifications in Austin, Texas should always provide for total accessibility. Never take for granted your great fortune of having free and total mobility because your situation could change in an instant.  In effect plan for your unthinkable changing future no one could have fathomed.  This consideration should always take precedent when compiling your list of specifications not only to satisfy the legal ADA parameters but as a means of providing equal comfort for all patrons.

     There are numerous published federal, state, and local guidelines but your local municipality is the dominant entity to satisfy.  Federal regulations are a good starting point but these have been revised from state to state.  However all enforcement begins with the accessible route and ends at the bathroom in question.

     Commercial construction professionals considering any fine bathroom upgrades should begin with the entry door.  Is the width substantial  for a wheelchair to enter and if so  does the closer make the door too hard to open for the impaired?  Once inside is there  adequate floor space for a 5' turning radius?   A typical one toilet  and one ADA compatible sink basic restroom measures 7 feet by 7 feet.  New commercial cabinetry at the vanity should be built to provide the proper top height and have roll under capability protecting against scalds from the plumbing pipes.  Other pertinent questions to consider include; is the urinal in a men's or unisex facility the correct height and is there room for access meeting all ADA guidelines?  Does the partition layout provide for at least one handicap stall with adequate room and entry and does it contain a comfort height toilet?  Do you have the correct grab bar configuration for the stall in question?

     Once these criteria are met you must now consider any dispensers for paper towels, soap, and toilet paper or any other fixed amenities.  Are they located at the proper height and is there a reach factor not taken into account?  Do you have blade handles to control the faucet at the vanity? 

     Compliant ADA accessible bathroom upgrades or remodels are no longer considered to be over the top or a needless expense.  You never know when you yourself might need help with your own bathroom needs following a temporary or permanent life changing situation.

An Accessible ADA Vanity With Roll Under Capability

     A combination of six faces defines nearly any given room.  The four walls receive the most preparation since they are usually the focal point as one enters the room.  Much time is spent to achieve just the right color, texture, and appearance to create that lasting impression.  The fifth surface, the floor, is generally designed for durability and comfort keeping with the rooms color scheme.  It too has a great deal to do with the general feeling of the room and as such is always considered in conjunction with the walls.  The final surface at the ceiling level is hardly ever taken into account in the finish schedule beyond that of getting a coat of color scheme blending paint. 

     One may never realize this last face even exists until they are lying in bed staring upward at a very common and unimaginable sight.  This most recently neglected surface having  such great potential has simply been made boring with the invention and use of drywall.  The old out of sight, out of mind gesture kicked in following the sheetrock revolution.  Consulting with a residential construction professional in Austin can give you some workable ideas.

     Long before drywall was slapped upon the ceiling and left to disappear in monotony, ceilings were both ornate and beautiful.  Wood was generally used on the ceiling enabling beams, coffered units, and box ceilings to be limited only by creativity. Klapp board houses had boarded ceilings covered with cheese cloth so that colorful wall paper could be hung.  Beaded and v-groove boards were another way to make ceilings interesting.  A metalic look was obtained using stamped tin panels of many patterns.  When all else failed and a homogeneous look was desired plaster was used.

     The look of fine cabinetry along with detailed woodwork and trim can be used on the ceiling to make any job more interesting and "kick it over the top".  You can combine creative  woodwork with faux or actual metal surfaces for that certain but different look.  Beamed and coffered ceilings also create a warm and rich feeling that is beyond the norm. Any use of these special ceilings will give any bath or kitchen upgrade a unique overall feel and look.  They can enhance bedrooms, home offices, libraries, vestibules or any room you'd like to reveal a looming accent.

     If you plan to remodel the ‘food production room’ in your home, then choosing your kitchen cabinets is probably going to be part of the plan. Not surprisingly, kitchen cabinetry is up for scrutiny in terms of the modernization tsunami changing home decor trends in recent times.

     Modern cabinets are breaking away from the ornate design found in traditional cabinet styling, rather reflecting minimal trends such as simple, clean design features. Streamlining and modernizing kitchen cabinetry or the storage cabinets used in bathroom transformations works in tandem with other kitchen or bathroom furnishings.  The use of new-age quartz countertops with complimentary glass tile backsplashes is becoming the norm.

     To the untrained eye a cabinet is just a box within a given space that fulfills a storage need.  But have you ever taken the time to look closer at the cabinet's makeup beyond the cost?   Before investing your hard earned money into cabinetry for a fine bathroom or kitchen upgrade take some time to get acquainted with the cabinet's parts and pieces.

     Cabinets are like anything else in our lives and sometimes we can be deceived by the bells and whistles the cabinet manufacturers want us all to see.  They create a sense of false quality for the consumer by blinding them with noticeably concealing finishes  masking the innermost important aspect of the cabinets general makeup.  In the North American face frame cabinet type the use of hardwood stiles and rails covered by hardwood cabinet doors fills the bill.  The most important weight bearing carcass sides, the top, and bottom or floor in a base cabinet are buried by the outer window dressing. The makeup of these aspects  is not aesthetic but structural.  These are the parts that sit perpendicular to the floor holding up the cabinet top and whatever is upon it.  They may cut this expense by using 1/2" or 5/8" thick matrix materials like MDF or particle board and covering these with a vinyl similar to shelf paper that creates "picture wood"of any wood species.  The European frameless cabinet types are generally covered entirely in a thin plastic exterior as in the case of melamine which covers up the particle board insides.  Check out the picture below representing how a simple plumbing leak creating melamine failure has lead to an entire cabinet replacement.  This customer had no choice!

     Our kitchens are no longer the "Orphan Annie’s” of our homes. This space now integrates with the rest of the home, and beautifully remodeled kitchens now serve as the main meeting space for our friends and families. You can even have wireless built into the kitchen cabinetry to power up all manner of gadgetry. It all goes to prove that kitchen cabinet design trends are moving in line with advances in technology, and why not – kitchens are the hearts of our homes.

     Their next trick is to associate quality cabinet type buzzwords like dovetail jointed drawers, European concealed cup hinges or other specialty hardware, special finishes or paints, and hardwood trim with faces as mentioned above.

     Fine cabinetry Austin, Texas consists of an entire 3/4" plywood carcass with a 1/4" plywood back.  The plywood gives you some moisture protection against a leaking sink drain trap or faulty supply line or stop valve.  European frameless cabinets can be painted on the interior using oil base enamels then covering all the visible exterior surfaces plus the doors and drawer fronts along with their edges with any choice of high pressure plastic laminate.  North American face frame cabinets can either be painted or stained and finished with polyurethane.  The finish on the plywood makes even more less vulnerable to moisture problems. 

     Don't get sucked into thinking that quality is behind the brightest glowing box on the sales floor and never forget that you get what you pay for in this life especially where cabinetry is concerned.  Do your homework!

     In the early 1800's, solid glass blocks were used as single units to light both ship's bowels and cellars in Europe.  In the early 1900's, second generation hollow glass blown  blocks resembled hexagonal open ended bottles.  They had condensation problems and were produced individually by artisans making them too expensive for general use.  In the 1930's machine production produced more uniform shapes that were easier to work into mortar.  The new units offered advantages in both thermal and noise isolation. Today's modern glass blocks for use in glass block bath designs Austin are still produced in this same way  taking two molded glass halves with a hollow interior and melting the parts to fuse them together.  A vacuum is formed in the block's interior to prevent condensation.  This evacuated "dead air" space provides for the block's thermal and sound reducing qualities.

     Using a fascinating building component composed of glass that is both fragile and sturdy with superior eye appeal allows for endless creativity and advantages.  Sound reduction as mentioned above along with thermal qualities for energy minded construction techniques are evident due to their air tight nature.  Both security and privacy is achieved by their light transmitting capabilities enhancing any bathroom transformation. This factor alone explains why glass blocks were first used in both commercial and industrial applications.

      Fine bathroom upgrades can benefit from glass block shower designs used in wall surrounds, support walls beneath whirlpool tubs, exterior shower windows, and low screening walls for privacy around spas.  Glass blocks can also benefit fine kitchen upgrades in many ways.  They can be used in islands, as supports for peninsula eating bars, or between your wall and base cabinets to provide natural light for the countertop work surface. Other uses of glass blocks are around the entry door as transoms or sidelights, in guard rails at balconies, room partitions, or sharing light from an adjacent window lit room.  Light shafts can give natural light to areas without having an outside window within the elevation.

     The light diffusing capability of glass blocks allows for back lighting projects using minimal amounts of artificial sources.  The glass blocks amplify a small amount of provided light to enhance a given area.  Artificial light sources include rope lights, incandescent bulbs, or fluorescent fixtures.  Furthermore using colored bulbs can provide any desired mood lighting creating chromotherapy results.  The glass block raw edges defining the entrance to an area can either be covered in an accenting tile and glass tile caps are now available.

      Modern glass blocks are available in many patterns, both transparent and opaque, as well as a variety of colors.  The  different sizes available allow for tremendous design opportunities while special shapes provide for curves, forty fives, and ninety degree angles.  Solid glass bricks are now available to be enhanced bu LED lighting.  Designs are limited only by one's imagination.

Glass Block Shower Designs Provide Warmth And Beauty

     I am a building professional who has been participating in Austin commercial office remodels and tenant finishes for over 30 years.  I've watched beginning business owners sign a lease and blow through their seed money purchasing costly ammenities like window walls or commercial cabinetry that could have been staged later after their initial door opening and they've logged their first dollar. 

     The beauty of metal stud walls below a grid ceiling is the ease of altering a given situation or floorplan.  It is easier to add or remove these walls than it is the ones within your home.  Electrical devices can be easily added or a lay in light fixture placed within the grid for additional lighting.  That is why the systems were created since not every office configuration will work for every tenant.   Even the door and window systems clip together so that they can change locations without being destroyed. 

     First find a trustworthy leasing agent with a good portfolio of available space for lease.  If you're just starting your business find a property that you can live with for a while until your cash flow allows for office improvements.  If you're established check and see if there is room for any needed expansion.  Check out things like break rooms in nearby suites for future plumbing needs so that you can share a costly drain for sinks.  Locate the electrical room because shorter wire runs for future circuits can save you money. Where is your space in proximity to the restrooms?  Are the fire exits marked?  Is the building ADA accessible?  Next negotiate a multiyear deal so that your rent remains at a constant level. 

     Once you move in it's time to plan for the immediate future.  Remember that any improvements that you make that are attached to the building must remain in place when you vacate.  Be smart and be sure any alterations you perform will  enhance the way the space fits your needs.  Think it through and who knows, you just might become a permanent tenant at your new address.

     Fine Kitchen Cabinetry in Austin, Texas is about the cabinet carcass and the finishes applied to it's front making up a Northern face frame or a frameless European look of your fine cabinetry.  Each type will accommodate mounting doors using a concealed cup Euro 32 mm bore hinge and installation is accomplished by varying the type of mounting plate that attaches to the carcass. The mounting plates are specific for the design once the doors are applied in an overlay fashion.  If the doors are recessed to be flush with the carcass face then other types of hinges can be used such as wrap around or door stile bore types.  Non concealed hinges come in many forms such a strap, Youngdale kerf units, flush, or offset and are used to create a certain style such as an antique look.  These hinges also come in many finishes like brass, chrome, or black to name a few.

Raised Panel Doors Can Be Square, Single, or Double Arched

     If you plan to remodel the ‘food production room’ in your home, then choosing your kitchen cabinets is probably going to be part of the plan. Not surprisingly, kitchen cabinetry is up for scrutiny in terms of the modernization tsunami changing home décor trends in recent times.

     Modern cabinets are breaking away from the ornate design found in traditional cabinet styling, rather reflecting minimal trends such as simple, clean design features. Streamlining and modernizing kitchen cabinetry works in tandem with other kitchen furnishings such as new-age countertops and complimentary backsplashes.

     To determine what style of kitchen cabinets are in your home you need to look  directly into their face beyond the doors.  Are they the face frame North American type or are they the European frameless version?  Fine cabinetry comes in many choices to suit your desires.

     The face frame North American type has long been a popular cabinet style.  It is characterized by the plywood cabinet box, or carcass, having a 3/4" thick hardwood front frame  application of 1 1/2"-2" widths.  These are present on both the vertical components, or stiles, and on the horizontals called rails.

     The frameless European style is just the carcass without any face frame yielding only a 3/4" outward appearance at the stiles and rails.  Both the frameless and the face frame styles use the same carcass body enabling the same European hinges, drawer guides, and cabinet legs to be used.

     The greatest difference is seen once the door or drawer fronts are mounted on fine cabinetry in Austin, Texas.  The European frameless type makes the adjacent door spacings smaller showing less of the stile beyond.  The framed units have more space between the door applications showing more of the stiles and rails beyond. 

    Frameless is a little less expensive to construct than the face frame style so that it really becomes a matter of personal preference and different styles can be mixed within the same house using one type in the kitchen and the other in the bath.

Typical Face Frame Look

     Typically bathroom vanities are 21" deep and approximately 29" tall. The depth is not a problem but most folks would prefer a universal design height of 34".  This height will work for your son or your father making the vanity more accessible to all.   Fine cabinetry is a must for any bathroom makeover.  As for the vanity, you can work your way down from the upgraded cabinet top that has been installed at the correct height for you.  The vanity should have adequately accessible storage satisfying your needs.  Incorporating  easy operating and properly sized drawers and pull out shelves within the design can be very beneficial.  Linen, medicine, and "over the potty" wall cabinets need to be well thought out. The correct species of wood used for the construction of your fine cabinetry and the style of you cabinet doors are two very important factors to consider.  Remember, you do have a choice and you are going to be looking at these new cabinets for a while.

     There are basically two styles of ADA vanities that comply with an unobstructed 27" tall roll under area below the sink.  ADA sinks with a rear drain location provide for better plumbing drain hook ups.  This modification has everything to do with both the water supply lines and the waste line connecting the sink.  There must be provisions made to protect the user from being scalded when coming into contact with any one of the plumbing pipes serving the sink.  These connecting pipes may become heated merely by the water passing through them creating the problem.  The open type model should always receive both waste and supply insulating jackets applied directly to the pipes providing protection for the wheelchair user.  The closed model concealing the pipes will be equipped with a removable face or face board covering the pipes.  This pipe concealing panel must be installed at the correct wheelchair user clearance angle.  This allows for the needed unobstructed legroom required for the  user.  The vanity can extend beyond the sink but the area containing the sink is required to have this roll under capability.  This section of the vanity top must not be any taller than 34 inches above the finished floor with sufficient lower leg clearance.  Clear unobstructed reach distances around the counter top area must be observed.  Any motion controlled sensors integrated into the various dispensing devices and/or plumbing fixtures throughout the restroom present a true hands free benefit to all the restroom users.  If these aren't in the budget then at least wrist handles used for controlling the faucet can be incorporated into the design of the vanity.  Furthermore, automatic flush valves should be used on all toilets and urinals that provide for hands free use.

    A completely serviceable special needs bathroom must contain at least one ADA vanity and the accessible route must be defined.  The vanity must be one with a clear underneath scald protected area having an unobstructed roll under capability for wheelchairs.  These new residential vanities do not need to look institutional.  They can be designed like any other piece of fine furniture.  A five foot turning radius allowing the wheelchair to maneuver into any approach must also be associated with the ADA vanity.  A 36x48" clear approach area to the vanity must be observed and this can overlap the five foot turning radius.  The area of travel will then be enhanced by an unobstructed clear accessible barrier free route dedicated to reaching the vanity. 

     Conventionally, the master bathroom has featured a giant master bath tub. This might be a traditional tub or a jetted unit – but it seems that more and more clients are asking for something else. They are saying ‘no’ to the large master bath tub taking up more room that could be used for other activities. Specifically, the current trend is for smaller, freestanding tubs with stand alone larger custom showers that might include body sprays, steam showers, duel heads, etc. or maybe no tub at all. The tub no longer needs to take up so much of the usable square feet as the main focal point in the bathroom. Most likely, large showers will remain popular, while tubs will remain a more personal choice. There will likely be a certain group of people who really enjoy and want a nice long bath, regardless of the trends. Each situation is personal, and a home should be full of personal choices.    

     Keep in mind that moving plumbing, especially drains, is one of the more expensive aspects of a fine bathroom makeover involving floor demolition.  If you can limit and control the costs involved with this issue you will have more money to spend on the things that show off your endeavors. Keeping this in mind will make your Austin bathroom remodeling a success.

     Start with your vanity cabinet(s) to see if the proper amount and kind of storage is present.  Can you accomplish your needs by using specialty items like pull out shelves, miscellaneous storage add ons as in wire pullouts, tilt out trays, or simply drawer inserts separating cosmetics or medicines?   If this isn't enough, your vanity cabinet can be replaced with something that's been custom made or you may be able to find an off the shelf product that solves your storage problems.

     How about your existing conventional tub?  If it is no longer used or you have another tub in your other bathroom it can be transformed into a shower within the same footprint.  You'll need to decide if you want a door and bring in the sides for the correct opening with either glass blocks or custom tile work on stick frame type construction.  A walk in shower without a door requires a large enough area to enter so that the shower head is off to the side.  Today's custom walk in showers can get pretty fancy with body and rain heads but remember these require a larger size supply line than is normally standard.  Composite shower pans or liners beneath the floor tile can be composed of either a custom fiberglass application or the proper vinyl material.  Waterproofing is the most important aspect of shower building and all precautions must be taken.

     Changing your toilet is an easy way to change the look and efficiency of your bath.  Older toilets use too much water when flushing and leaky flappers or malfunctioning fill valves are also water wasters.  Toilets come in either a round or elongated shape and in standard and somewhat taller heights according to your comfort level.

     Always use energy minded construction techniques in Austin, Texas and conserve water when making alterations to your home.

     Now that you've worked so diligently to attain the most efficient envelope for your building it's time to consider the finer points and a few energy minded construction techniques. This is why home remodeling Austin, Texas is a unique problem and furthermore why professional residential remodelers exist.   From here on out you will be dealing  with the penetrations going through your envelope perimeter that are deducting from all your efforts.  These areas include not only the electrical boxes, wires,  pipes, and registers that are coming through your walls, floor, and ceilings,but in particular the doors and windows that connect us to the outside.

     Austin house remodeling criteria demand that any penetrations concerning your utilities must be dealt with using expanding foams, caulks, or gaskets that limit infiltration into your envelope.  You can use clear paintable caulks in conjunction with all your interior trim eliminating small leaks that add up to large problems.  You can also caulk your A/C buckets to the ceiling before replacing the grilles.  Use insulation dams above attic stair units and weatherstrip the pull down door to the ceiling.  Repeat this procedure at any additional attic skuttles within your building.

     Your return air closet can also be a conditioned air thief.  Caulk all inside corners of the closet and seal your air handler to the platform it rests upon.  Weatherstrip the closet door.  If you have a gas furnace you can either remove the closet ceiling or install combustion air pipes that connect the closet to the unconditioned attic above.

     Now to attack the most wasteful of all the efficient envelope penetrators that connect us to the great outdoors-your windows. They make up a great percentage of surface area in your now upgraded and insulated exterior walls.  You must access whether or not to replace the original leaky windows and what value they add while preserving the look of your exterior.  If you choose to keep them, either efficient storm windows or insulating shutters may be installed on the interior. If, on the other hand, you favor replacing them always remember a good rule of thumb.  A single pane of glass only offers an R-1 resistance to the outside.  You are basically dealing with aesthetics  so don't be taken in by all the bell and whistle talk.  The main specification to consider is the E-factor concerning how well light is transmitted  into the building helping with direct gain problems during the summer months.

     All solid exterior doors offer insulating qualities through their makeup and must be weatherstripped.  If your doors contain glass inserts treat them as windows installing insulating shutters on the interior or a storm door on the exterior. Any penetrations through the conditioned envelope reduces it's total efficiency.

    Now that you've taken care of the energy being wasted "through the roof" how about those walls and what energy minded construction techniques can be utilized?  What type of construction makes up your walls and what are the best ways to go about eliminating some of the waste caused by air infiltration?  Let's define what home remodeling Austin, Texas means.

    Any remodeling contractor will tell you that Very old buildings have wall construction which is limited only by the materials that were available at the building sight for any specific time. These structures were normally composed of sod, masonry,  or logs that were chinked  with mud set into their joints relying on the principle of thermal mass.  By building thicker walls the same logic of the R-factor was used.  It took longer for outside temperatures to transfer into the building through these massive resistant walls into the living space.   

    Once lumber became available it was used at a premium.  The presence of clapboard or weather board construction came about using one by (one inch thick) boards in varying widths on  both sides of a 2x4 stud forming the outside walls. 

    The joints between the boards allowed air to infiltrate the building.  Batten boards were nailed over these joints on the exterior to eliminate some of the air flow and  later cheesecloth covered by wallpaper was applied on the inside boards.  The walls still had too much air infiltration relying on the dead air space and the composition of the wood itself to comprise the R-factor.  Finally 1/4" sheetrock was applied over the wallpaper as a first generation drywall application.

     If this clapboard system is plaguing your building you must access which side of the wall you need to attack.  Do you need new exterior siding that allows you to install and bury additional rigid insulation or desire a newer looking drywall finish on the interior? The only way to gain access to your stud space for applying batt insulation is to remove one side of the clap boards.  The kraft face must be turned toward your living space to create a vapor barrier against the outside and R-13 is the thickest product you can place in a four inch cavity.  Don't be misled by an offer using a blown in product that can be held up by wiring and never reach the bottom of the wall cavity which defeats the whole process.

     Once you have accomplished this task you have helped to maintain your envelope but you need to look down.  If your floor is on a pier and beam structure do you have an underpinning present?  It's purpose is to stop the wind from robbing you of additional infiltration from below your floor.  If present, the underpinning can eliminate having to install insulation between your floor joist.  It acts by literally raising the constant temperatures that existing naturally below ground.  This natural occurence will temper the crawl space beneath your floor joists and prevent energy robbing infiltration.  You now have a reasonably efficient envelope given your existing situation.
