(See? So small I couldn't even get a picture of it with the shower stall! The stall is to the left in this picture.)
So I did what any good wife would do: Give that bathroom to the Mister and take over the guest bathroom as my own.
This worked for a few years... until the guest bathroom shower curtain rod broke, and I was way too lazy to put the new one up. This meant showering in the gross stall, and that brings me to noticing the peeling.
I had noticed that the shower head pointed directly on the back tile, and where the water hit the grout was nearly gone. This is an old house, built in the 50s, so old grout isn't surprising. What most people do is regrout at some point. No one did, and we sure as heck haven't. We knew at some point we'd renovate the bathrooms, so we haven't done much with them.
Until last summer.
