NON-SLIP BATH MAT: Our bath mats are equipped with suction cups that give the mat good grip and ensure it stays in place on your bathtub or shower floor. They are also heavier and thicker than other mats and won't roll up. EXCELLENT DRAINAGE: The drainage holes on these tub and shower mats allow water to drain more easily and also help them dry faster, keeping your tub clean. Ideal for home, spas, gyms, and showers. DURABLE AND SAFE BATH MAT: This non-slip bath mat with suction cups is made of durable PVC material that ensures reliable slip resistance. MACHINE WASHABLE: The bath mats are machine washable. Simply machine wash in cold water with mild detergent and let it air dry. Small dots on the raised surface: The surface of the pebble-shaped raised bath mat is covered with small dots that are in close contact with the footboard, providing a non-slip effect and a double foot massage to relieve fatigue.
