Upgrade a three-wall alcove shower with this 48 in. x 30 in. rectangular acrylic shower base, designed to provide a clean and durable foundation for everyday shower use. The one-piece shower pan features a right-positioned drain and a gently sloped floor that directs water toward the drain to help minimize standing water. A subtly textured floor surface helps provide traction under wet conditions, while the low front threshold provides convenient step-in access into the shower. An integrated 3-sided tile flange runs along the back and both side edges of the base to help manage water at the wall-to-base connection when properly installed and sealed. The smooth, nonporous acrylic surface is easy to clean with a soft cloth and mild household cleaner and is designed to resist yellowing with regular care. A drain assembly is included for a convenient installation setup. The crisp white finish works well with a variety of shower walls, tile styles, and bathroom fixtures. Designed for straightforward installation, this shower base can be installed as a DIY project; professional installation is recommended to ensure proper leveling, support, drainage, and sealing.
