The Mainstays Rubber Bathtub Mat is a plain white 18 x 36 inch mat that sits on the tub floor and gives a cushioned surface underfoot. Suction cups on the underside hold it to smooth tub surfaces; it is not meant for textured or tiled floors. It is a basic, low-cost pick for renters and households that want slip resistance and comfort without extras. Rivals in this class often add drainage holes, textured tread or antimicrobial treatment, which this mat does not offer.

Owners rate it well overall and mostly praise the cushioning and the grip on smooth tubs. Complaints center on the flat top holding water and on the mat discoloring or growing mildew with use.
The Mainstays White Rubber Bathtub Mat is made for use inside the tub. It gives the tub floor a cushioned surface underfoot. The mat is rectangular and measures 18 in x 36 in, with a smooth, solid top and a cushioned feel.
Suction cups on the bottom help keep the mat in place. It is intended for smooth tub surfaces only, not textured, tiled, or other non-smooth ones. The styling is simple white.
