This shower foot rest uses a 5 in. industrial suction cup to provide a stable pedestal for washing feet or shaving legs. The design relies on a smooth, non-porous tile surface and a clean wall area to secure the suction cup with an integrated air pump. A red warning line runs around the top edge, giving a clear visual cue about the unit's current seal status. Before use, press the pump until the line disappears to ensure a reliable grip, and periodically recheck it during use to avoid unexpected detachment. The tile you install on should be smooth and have a diameter greater than 5.2 inches to accommodate the foot rest, and the overall load capacity is about 337 pounds, which helps reduce bending or reaching strain. The assembly process is straightforward: clean the wall, place the suction cup, pump until the red line disappears, and then attach the pedal. It is intended to support the foot rather than bear full body weight, so always confirm the seal status before stepping on it. This setup supports foot care tasks without changing permanent fixtures, and the safety line acts as a simple safeguard against accidental release. If the seal weakens, remove the unit and reattach after cleaning the wall. Color: White. Material: Plastic.
