Hi everyone, I'm planning my guest bath. My elderly parents will be frequent visitors, so I'm planning with their ease of use in mind.

I have a low tub and I'm planning to install a grab bar vertically close to the edge of the shower to help them step over. does this grab bar need to be textured? I'm thinking it should be, but have looked at several that are smooth and say ADA compliant. Seems like in a vertical installation their hand could slip more easily?
