I’m someone who used my main (only) shower/bath to learn this stuff on. My wife happened to be 8.5 months pregnant. Don’t be me.

I got it done, it works, it doesn’t leak, it looks how I want. But it was stressful AS FUCK, and my extremely pregnant wife was showering at the YMCA for almost a week while I was dicking around with this stuff (we re-tiled the whole tub surround, including replacing all the drywall with cement board, reinsulating, vapor barrier, etc). Like…I don’t regret doing it because we had tiles falling off and it needed to be done. And I’m glad I learned all the things I learned.

But it was not easy, I ran into tons of shit I was not prepared to handle and had to figure out on the fly, and it was very time sensitive and stressful. I might have chosen to start earlier if given another chance lol.
