The Ella Standard Barrier Free, Roll In Shower 48" x 36" (4 Piece) is manufactured using premium marine grade gel coat which creates a smooth, beautiful, long lasting, anti-slip shower surface. Ella Standard Barrier Free, Roll In Showers are constructed using wood and steel reinforced walls providing flexibility for seat and grab bar custom installation. The integral self-locking aluminum Pin and Slot System connects shower walls and the pre-leveled shower base to allow for easy front side installation. Once the multi-piece unit is assembled the precision fit seams become grout lines which can be nicely finished with caulk. Ella Standard Barrier Free, Roll in Showers come with a textured slip resistant Grip Sure™ floor, a collapsible white rubber dam which allows for easy wheelchair roll over into the shower stall and keeps water inside the shower. The standard package features a center drain position with 3 integrated, molded soap ledges on the back panel, color selection (white, bone or biscuit), and a 2 inch chrome shower floor drain with friction seal. The Ella Standard Barrier Free, Roll In Shower Base is engineered to allow for above the floor installation with a steel reinforced beveled threshold for wheelchair entry without the need for recess or a ramp. The shower base is equipped with a factory engineered self-sustaining base, (mud-set not required) for proper water drainage and fast installation. All Ella Standard Barrier Free, Roll In Showers are warranted by the manufacturer against defects in structure and finish for a 30 year Limited Warranty from the date of installation.
