The Brompton Soft Cushion Waffle Shower Mat features skid-resistant suction cups to help hold it securely in place, and its cozy cushion texture adds comfort, creating a relaxing shower experience. This product is treated with an agent to resist mildew. The phthalate-free bath mat fits standard-size tubs and can be easily cleaned by wiping with a damp cloth. (For best results installing tub mat: Make sure tub is clean. Wet tub. Place mat in center of tub and press firmly to anchor suction cups. Continue filling tub and step carefully onto mat in 5 to 6 places to ensure mat is anchored to tub. After use, remove and rinse thoroughly, wipe clean with a damp cloth and mild bleach.)
