It is not essential but it is strongly recommended. A mat stops heat draining into cold ground, protects the tub floor from grit and sharp objects, and adds a layer of cushioned comfort underfoot.

Each foam tile is 57 x 57cm / 22 x 22in and 10mm / 0.4in thick. Nine tiles lock together with jigsaw edges to make 165 x 165cm / 65 x 65in, which covers most tub footprints.
