This is a bathtub handrail that can be easily installed with suction cups. I purchased a set of 2, but only used one, so I am selling the other one. - Model Name: TAILI Bathtub Handrail - Color: Gray - Installation Method: Suction Cup ・The handrail is suction-cup based and can be installed without drilling holes in the wall. ・The handrail has non-slip silicone particles for a safer and more convenient grip. ・Water and moisture resistant, preventing slips in wet bathrooms, bathtubs, showers, and toilets. Handrail Size: Approximately 42.8 cm Suction Cup Size: Approximately 9.5 cm Weight Capacity: 110kg The suction cups will only adhere to smooth, non-porous surfaces such as metal, glass, ceramic tile, stainless steel, and acrylic. Please note that they are not suitable for surfaces such as uneven ceramic tiles, textured boards, unfinished marble, wallpaper, tile gaps, and painted walls. Thank you for looking.
