I'm iconsidering the idea of removing the tub in my elderly parent's master bathroom and having a shower stall installed. This would be for safety reasons mostly. Any suggestions on an inexpensive unit which is easy to install?
The first consideration is how hard it is to access the drain lines under the floor. If your over a basement or crawlspace it won't be big deal, but if your on a slab it can get very expensive because, while a tub has an 1-1/2" drain, a shower requires a 2" trap & drain line.
Yes, it can be done. Lowes/HD sell shower pans that are retrofit to replace a tub (drain is on the end).
We did this in our bathroom. I put tile on the walls. I love it.
We also did this with my MIL's house, and DH used matching
fiberglass walls for her. No complaints.
Kohler/Sterling makes a line of shower and tub units that include safety bars on the wall panels. They can be kind of spendy, but they might be worth a look. I found one that was a special order return, and Lowes was selling it really cheap. I didn't even need the ADA bars, but it was such a deal that I bought it for our basement bath. The unit is easy to install, and the walls fit together so neatly that you don't even need caulk. It feels so clean!
kmcg - Good point about the safety bars.
If this for an elderly you probably should install grab bars even with a walk in shower. We did that too for my MIL.
Also, be sure to check your local codes about the drain. Some allow 1-1/2" drains as since many of us use low flow showers now it's not a problem.
I have put a rubber flat stopper over mine some times when I feel I need a foot bath. Even after washing may hair etc, it doesn't get close to overflowing.
