Definitions and Terms

Every industry has its own language and when you are designing a bathroom that includes an air system bath it is helpful to understand the language we use. Below is a series of words and phrases along with the associated definitions. Many will have a short description of how to apply the word in a practical way and others will refer you to another section of the website for more information as a short description is impossible. Most of these words apply across the industry and a few are unique to our organization.

Setting - is the framework that will support the bath and the finish that will surround the bath. There are a variety of types of settings including drop-in, flush-mount, under-mount and free-standing, each of which is briefly described below. In designing your bathroom it is important to know the differences.

Drop-in settings are framed enclosures where the intent is to provide added flat space around the perimeter edges of the bath that will be finished with a solid surface material such as tile, granite, or other composite surface. The frame is built in one of two ways. One way is to build the frame with an area where the bath will be dropped in after the solid surface has been placed. The second method is to build the frame with a solid wood surface across the top of the frame where the solid surface is placed and then a cut-out in the shape of the bath is made so that the bath can be dropped into the frame. To utilize this setting you need more space than the outer perimeter dimensions of the bath itself. When designing, you want to make certain you have contemplated the space needs. Bath shapes that can be used in this application are rectangular, oval, corner and depending upon the rim shape, some clawfoot or slipper baths.

Flush-mount settings are framed enclosures where the bath will be placed into the frame so that two or three sides of the deck of the bath will rest on a wood frame. This usually requires that a flange be added to the two or three edges of the bath where it will rest on framing so that when the wall surface is later added the walls will sit flush with the bath. Typically, flush-mounts are used when space is limited and when a bath with shower combination is desired. This method requires the frame to be the same size as the outer perimeter dimensions of the bath itself.

This application is almost always a rectangle or corner shaped bath as ovals, clawfoot and slipper shapes are horribly difficult to flush mount with curved walls. However, not all rectangles and corner shapes are appropriate for this application and a shower with bath combination limits the selection even further. Selecting a rectangle or corner shape bath for this application depends in large part on the upper deck design of the bath, especially if a shower and bath combination is planned. Many of these shapes have upper decks with raised areas and many have rolled contours.

A rolled contour makes a tiling flange and flush-mount impossible since the rolled contour ends at the very edge of the bath. There other raised elements such as head rests that make it unwise to use the shape in a shower with bath combination since the contours of these raised surfaces may cause shower water to run of the deck and out onto the bathroom floor. It is important to think through your likely actual use and visualize the raised surfaces in a practical use application.

Under-mount settings are frames where the intent is to feature a solid surface and partially or completely hide the upper deck of the bath. This is done by building a frame with a flat wooden upper deck on top of which the solid surface if placed. A cut-out is then performed to match the inner dimension or nearly the inner dimension of the bath wells shape. The bath is then placed underneath the framing and raised to the underside of the frame cut-out and positioned so that when looking at it from above you see the solid surface material and then directly into the bath well. The critical design consideration in this application is the deck of the bath. The bath deck has to be flat with very little slope.

All bath decks, even when flat, slope slightly from the outer edge in toward the bath well. This is done to encourage water that gets on the deck is more likely to run back into the bath and not out onto the bathroom floor. In an undermount, the final appearance is dependent upon the space between the solid surface and the bath being slight so that the caulk seal that will be placed there is of no significant visual distraction. We have nine products where we have designed the deck so that they can be under-mounted. We use a 1/8" tolerance as our caulk seal gap standard.

Free-standing settings do not usually involve any framing at all. The intent here is to feature the bath itself. Only baths designed for the purpose are suitable for this application. These are typically called clawfoot, slipper or island baths. The design consideration here is to have a bath in free space that can be approached from one or all sides. This requires that you know the outer dimensions of the bath so that you can plan space and plumbing appropriately.

Bath well - the area of a bath where you bathe. Every bath well has a shape, and dimension. In thinking through a bath you want to know as much about the shape, width and depth as possible to make a decision about comfort.

Deck - the flat surface surrounding the bath well. It is important to know the dimensions of the deck space for two reasons. The outer dimensions tell you what space you will need. Our drawings provide additional dimensions showing usable flat deck space so that once you choose a bath shape you can choose faucets and valves that will fit on the deck or choose faucets and valves knowing you will have to mount them elsewhere.

Reveal - the vertical flat surface around the sides of the bath below the deck whose lower edge meets with the tile, granite or other surface material of the bath enclosure. You want to know the dimension of the reveal in order to visualize how far above the finished surface (tile, granite, etc.) the bath shape will rise.

Drain - the waste water drain located on the floor of the bath well. Drains can be located on the left, right, center, left center or right center of the bath well. This is especially important to know as you plan your bathroom under a remodeling scenario. Most drains are right or left hand meaning the drain is oriented to one end of the bath as you look at it. This is because most plumbing infrastructure (hot and cold water lines and drain pipes) run up through a wall with the trap extending off the drain pipe to the drain of the bath. This is the most economical placement of plumbing infrastructure. In a retrofit you either have to choose a bath that has the same drain orientation as your existing bath or a different drain location. A different drain location will add time and expense to the project as the plumber will have to rip up flooring to re-plumb the infrastructure and get the drain, trap and drain pipe in the proper locations, then refinish the flooring.

Overflow - the bath water overflow opening located on the inner side wall of the bath well.

Waste and Overflow - the hardware piece that connects behind the bath providing a pipe that catches the overflow of bath water and directs that water down to the waste outlet in the bottom of the bath and the trap in the floor. This piece of hardware is critical to removing water and you will need to choose the finish of the pieces that are on the visible inside of the bath well and the type of drain mechanism (lever, tip-toe, push-pull, turn-style, pull chain, etc.) you want.

Tiling flange - material that is attached to one, two or three sides of the bath reveal to water proof the edges of the bath where they meet a wall. The flange sheds any water out onto the bath deck that gets behind the tile on a wall surface or any other wall surface such as granite. Tiling flanges are made from an assortment of materials such as PVC and fiberglass. This is a critical element when you are recessing a bath and using it as a shower enclosure in addition to using it as a bath.

Integral tiling flange - same as a tiling flange but it is molded at the same time as the bath shape is molded and becomes an integral (not removable) part of the bath shape. The flange is made out of acrylic like the bath and reinforced with fiberglass. It is the best way to seal against water penetration when recessing a bath as a shower and bath enclosure. Be careful to choose the correct drain orientation if you are also choosing an integral tiling flange because if it is wrong your bath will be backwards.

Skirt - this is a separate decorative acrylic molded piece that is used to finish the front of a bath. When you place a bath in a setting (framed area where the bath will go) you can order a separate acrylic shape that compliments the appearance of the bath. Skirts are field installed and all plumbers/installers hate them because they have to be cut to size at the location. They are made oversized intentionally so that they can be adjusted to the specific dimensions of the setting. They have the advantage of being removable without tearing out the bath if you ever need to get under the bath. Some require that tiling be removed around the edges and others have access panels (acrylic panels that are attached to the skirt itself), which can be removed without any surgery to the bath setting.

Integral Skirt - same as above except that the skirt is actually a part of the mold used to create the bath shape and can not under any circumstance be removed. Some integral skirts come with removable access panels. An integral skirt makes the entire bath installation very easy and plumbers/installers have far less disdain for integral skirts.

Water fall fill spout - a separate shape added to a bath mold before being formed that results in a raised shape integral to the bath into which we pre-plumb a single water line. This allows for an attractive visual element of the bath and also increases dramatically the flow rate of water to the bath.

Grab Bar - is an acrylic shape that can be added as an option to most of our baths. It is shaped much like a handle and attached to the side or both sides of the bath well and used to grab hold of while getting into or out of a bath.
