- 2.2 BATHTUBS
-
- A. Bathtubs: Solid plastic, made of polyester resin and
- inert fillers, with polyester gel coat surface, gravity
- molded in inner and outer molds; complying with ANSI
- Z124.1 and addenda.
- 1. Gel coat thickness: 0.017 to 0.020 inch, minimum.
- 2. Fixture wall thickness: 1/2 inch, minimum.
- NOTE ** Delete all but one of the following color
- descriptions. If more than one tub is required and

- identification to each type included below.
- 3. Color: As selected from manufacturer's standard
- range.
- 4. Color: _________.
- 5. Color: As indicated for each type.
- NOTE ** Delete one of the following filler descriptions.
- NOTE **
- NOTE ** Standard filler is calcium carbonate which imparts
- no pattern or texture to the product, but when
- mixed with pigments can produce a marble-like
- effect which may be opaque. When aluminum
- trihydrate filler is used together with pigments,
- an onyx-like effect is created which is
- translucent.
- 6. Filler: Manufacturer's standard.
- NOTE ** Gruber Granatex gives the product a fine- or large-
- chip appearance depending on the color and type
- selected, producing a granite-like effect. Each
- manufacturer has his own formula for resin and
- filler, usually adapted to the climate in which the
- product is manufactured. Custom color production
- capability is available.
- 7. Filler: Gruber Granatex, providing "granite"-like
- appearance; color as selected from Gruber's full
- range.
- 8. Shape(s): As indicated below, made by using Gruber
- Systems, Inc. molds; mold numbers noted as "MK __."
- NOTE ** The following articles cover the bathtub types,
- grouped by general type for ease of selection.
- After selection of the tub required, it will
- usually be appropriate to eliminate the group
- headings "BATHTUBS - SELF-RIMMING," etc., leaving
- the tub required under the heading "BATHTUBS" with
- the general specifications.
- NOTE **
- NOTE ** If only one bathtub is required, it may be
- unnecessary to use the Type designations "Bathtub
- BT-___". In that case, simply delete the "BT-___."
-
- 2.3 BATHTUBS - SELF-RIMMING
- NOTE ** Self-rimming bathtubs are designed to be set into a
- deck of cast polymer or other construction, which
- can be the floor or a raised "island." For tubs
- that need to be set tight to walls, the integral
- (flat) deck type is better.

- handed -- they can be either lefthand or righthand,
