The Marine Board shower insert is made from a non-slip polyethylene material that is custom made to fit various shower base sizes. The shower base insert is used to level out the floor of a shower base to allow for easy wheeled access to the shower.
It is also used in conjunction with either a custom wood or rubber access wedge. It is installed with drainage holes and space on the sides that allow for drainage. It also comes with a convenient cut-out handle on the side to assist with placement and removal.
