Mustee Durabase Shower Floor
SMC Fiberglass
Material & Characteristics
Sheet molded compound (SMC) is a thermoset
material consisting of binding resins, crushed
stone, colorants and fiberglass reinforced fibers.
SMC requires heat and pressure to form into
shape. The internal glass fibers give thermoset
SMC it’s structural strength and the finished
product is extremely stable at high or low
temperatures. The color is molded throughout
the part and the hard surface has a high impact
tolerance. The SMC is chemical and stain resistant
as tested to ANSI-Z124.1.2 standards with a
classification of Type I (its highest rating). SMC
flows throughout the mold cavity during the
molding process allowing structural ribs, moldedin drains and slip resistant floor patterns to be
incorporated as an integral part of the product.
The thickness of the part can be accurately
controlled.
Production Process
The matched metal mold is mounted in a hydraulic
press, capable of generating in excess of 1,000
tons of pressure. The SMC compound is placed
between both halves of a highly polished, chrome
plated, tool steel mold. The mold is heated and
closed applying pressure for a pre-determined
period of time. The mold is decompressed and the
molded casting removed. The heat and pressure
molecularly fuse the compound to create the finish
product.

Sunburst Slip Resistant Design
Mustee’s Sunburst pattern is a registered and proven slip resistance design. The sides of
the pedal are tapered for easy cleaning. The pedals themselves all point towards the center
of the shower floor directing the water in an unrestricted flow to the drain. The majority of
the floor surface is flat for easy cleaning.
Front Threshold
The Durabase Shower Floor threshold has been modified with a reverse tapper of 2.5 +.25
degrees, angling it into the shower floor. The reference for proper draining was the Uniform
Plumbing Code – IAPMO/ANSI UPC 1-2009 Section 411.6 which states that the finished floor
of the receptor shall slope uniformly from the sides toward the drain not less than one-quarter
(1/4) inch per foot (1°) nor more than one-half (1/2) inch per foot (2°). Therefore the 2.5°
tapper on the revised threshold (2 ½” wide) is more than adequate to direct the flow of
water.
Further modification to the threshold is an addition of a barrier rib on the inside of the tiling
flange. With addition taper to the recess. The barrier rib is a hidden behind the tile for a
clean finished appearance.
