Built for hygiene, designed for you. The biggest difference in this shower base is the addition of the seat, which is 17 inches in height, ADA compliant, and supported by 8 stainless steel brackets underneath for excellent stability and durability, while both the seat and the base are designed for non-slip and sloped drainage, making it perfect for long term use. The base is made of 100% high quality acrylic that does not yellow and makes it easy to clean, all designed to make showering easier and more enjoyable.
