Bubble Bath Mat features hundreds of small, cushioning bubbles that gently massage tired feet. This clear bath mat is made of durable vinyl and features over 58 suction cups to provide reliable non-slip protection. Cleaning is a breeze - simply hang and air dry the mat after use, or machine wash with your everyday laundry. WARNING: Designed for use on smooth surfaces only. For your safety, do not install over grout lines, voids or textured/uneven surfaces; all of which negatively affect adhesion. This product is not intended for use on refinished surfaces. Always make sure that your mat is securely attached before entering or exiting your tub, shower or other slippery areas. No anti-slip product can prevent all accidents.
