Where to position a vertical shower/tub grab bar
We are having a new tub/shower unit installed and I want to add a vertical grab bar. On which side of the enclosure should the grab bar go -- on the side with the faucet and shower head, or on the opposite side? My gut tells me it should go opposite the faucet because that's the side I generally use for getting in and out of the tub. But the few photos I've seen have it on the faucet wall. Which side is better, and why? Thanks!
