I had an apartment where the landlord had clearly painted right before I moved in, and had done so with an ungodly thick layer of latex paint. That's fair enough for the walls... I hope it wasn't to cover up mold, but he was very thorough. He did paint over the outlets and some hinges too. But even worse he also painted the bathtub/shower combo. Like... the whole thing, including the sloped interior basin of the tub.

Not only is that fucking weird, it's also a major hazard as ot turns out. Did you know that latex paint is very slippery when wet? I do now. Had to cover the bottom of the tub in adhesive strips of traction tape to not crack my skull open. What's more, latex paint is not meant to be applied to bathtub, nor is it meant to be bombarded with hot water every day for months on end. So as you can imagine, shortly after moving in, paint would periodically bubble up and chip off

By the time I moved out, a little over a year later, almost all of the paint had peeled off the bottom surface of the tub revealing the heavily lime scale stained surface they tried to cover up. So glad they tried to kill me with a frictionless curved bathtub bottom rather than to replace, properly clean or even just leave the bathtub as is.
