Question: what is the difference between acrylic and fiberglass shower stall?
Answer: Acrylic shower units are reinforced with glass fibers and resin, but are made primarily from large sheets of acrylic. ... Fiberglass shower units are made with a polyester resin that is mixed with woven glass fibers and then sprayed or poured into a mold. The result, with either material, is a solid piece with no seams.
