Curtain. It’s cheaper. You don’t have to get onto the kids for not wiping down the glass after each shower. And, most importantly, the glass is a major hinderance if you are trying to help a child bathe, and/or if someone has an injury and suddenly needs help bathing... or if they can bathe independently it’s still more difficult to enter and exit a shower/tub combo when there is glass blocking half of the tub. (As we discovered when our adult daughter was visiting and she broke her leg and I had to help her bathe in my bath with glass, then I went to her home for a couple of weeks after her knee surgery and still had to help her bathe but she had a shower curtain.) We are currently building a home now and because of that experience, our shower/tub combo in the guest bathroom will have a shower curtain.

Also... all five of our kids are grown now, but during their childhood we had our fair share of broken arms and legs. Bathing was never a major struggle during any of it because we only had tubs with shower curtains and walk in showers with low curbs. We didn’t experience the glass door with a tub until our current living situation, and, of course, that’s when our daughter was visiting and broke her leg bad enough to need surgery. Oy!

The glass is a major hinderance if you are trying to help a child bathe, and/or if someone has an injury and suddenly needs help bathing.

Very true!
