This bathtub overflow cover is a functional silicone accessory designed to increase water depth during bathing by sealing the overflow drain. It prevents water from escaping through the overflow opening, allowing users to maintain higher water levels without spillage. The octopus-shaped design includes 8 small suction cups that adhere securely to smooth tub surfaces when wet. A central hole on top enables controlled water level adjustment by partially covering or uncovering it. Made from flexible, durable silicone, it accommodates common overflow types including snap, flat, toggle, and daisy wheel configurations. Installation requires no tools—simply wet the suction cups and press firmly onto a clean, dry, non-textured surface near the overflow. It supports consistent water temperature retention and reduces the need for frequent refills. Not intended for textured or porous tub surfaces. The device operates silently and does not interfere with standard drain function when removed. Its compact form allows easy storage and portability between different bathtubs. Color: Blue.
