The multi-layered shower base is made with a proprietary process that ensures the product is stronger and more durable than other products on the market. It has a thick layer of hi-gloss acrylic that is non-porous, attractive, and resists mold and mildew growth making the product hygienic and perfect for your home. You can change many inexpensive upgrades in your bathroom later, but you want to put the very best shower base or tub in your bath to ensure no leaks and save the expense of having to replace the unit later.
