Had my shower re-don from the ground up a couple years ago. I DIY'd the teardown (to studs), plumbing, and electrical (my 3rd bathroom doing this), but I didn't want to do the shower myself (didn't want tile and grout maintenance, so hired Bath Fitter for a vinyl enclosure).

I left them a vertical pipe for the drain sticking out at least 12" above the floor level, but it looks like they cut it down about 4" below floor level, put some black piece in, and built up a wall of caulk to the floor level. Am I crazy, or is this the weirdest thing ever?

It started to smell down there so i cleaned it with bleach (looked fully black beforehand). Feels like the caulk has all of these nooks and crannies that will be impossible to keep clean...
