Shower walls and pans are all solid surface products. Solid surface is a man made non-porous, low maintenance material composed of bauxite, acrylic polymers and alumina trihydrate. It can be transformed by heating, allowing unique shapes to be created. Its primary use is in kitchen and bath counter/vanity tops and shower walls and floors. A major appeal of solid surface is in its seamless nature eliminating areas for water to collect and requires no porous grout for bacteria to grow.
