NON-SLIP BATH MATS: Our bath mats feature suction cups that allow the mat to have a good grip and stay in place without sliding around on the bathtub or shower floor. It is also heavier and thicker than other pads and does not curl up. EXCELLENT DRAINAGE: The drainage holes on these bathtub and shower mats allow water to drain more easily and also help dry faster, keeping your bathtub clean. Ideal for homes, spas, gyms and showers. DURABLE AND SAFE BATH MAT: This non-slip bath mat with suction cups is made of durable PVC material, providing reliable anti-slip performance. MACHINE WASHABLE: The bath mats are machine washable. Simply machine wash in cold water with mild detergent and air dry. Small Dots on Raised Surface: The surface of the pebble-shaped raised bath mat is covered with small dots, which are in close contact with the foot plate, providing anti-slip and double foot massage to relieve fatigue.
