No drilling — moves with you if you rearrange, and holds steady when it matters.
A lot of grab bars require drilling into tile, which puts people off installing one at all — especially in a rental. This one uses heavy-duty suction cups with a locking lever, so it goes up in seconds and comes down just as easily if you need to reposition it.
Suction holds best on smooth tile, glass, or fibreglass. Clean the surface well before mounting, and check the seal indicator every so often.
