Sturdy and Durable - The shower handles are made of plastic, 2 suction cups with strong force, very sturdy and durable. You will not slip even when wet, providing a comfortable experience in the bathroom, bathtub, shower and toilet. NOTE: The product works best on a flat, non-porous surface. An uneven surface or textured surface will result in a suction cup that will NOT stick properly. Comfortable Non-Slip Grip - Two strong shower handle designs work on all non-porous and flat surfaces, including tile, glass, acrylic and fiberglass. The handle provides extra stability when getting in and out of the bathtub or shower for a comfortable experience. The suction handles for bathtubs and showers have comfortable, easy-to-grip handles that ensure a non-slip grip for more stability and increased safety. Tips - The shower handle is suitable for smooth, dry and clean surfaces. Clean and dry the surfaces thoroughly before installation to ensure smooth, non-porous surfaces. Check the stability of the suction cup regularly. This grab bar should ONLY be used to assist and support a person's body properly, not to support full body weight. Use with caution and test the strength of the suction cups before use. NOTE: The grab bars cannot be mounted on joints. Easy to install - The shower handle is easy to install, no tools are required and no drilling is required. Simply twist the latches to secure the bar in place. You can change its location according to your current needs. The grab bar will not damage the surface it is on and will not leave marks when placed correctly. Portable - The shower handle is portable and compact, so you can take it with you when you travel, easily install it in your hotel room or guest toilet, take it anywhere you need it, just push the latches down to secure or flip them up to release.
