When we purchased them we remodeled with pets in mind (vinyl and tile floors, furniture fabrics that can be cleaned easily and fenced in back yards). 

It is far too easy for a tenant to fabricate a letter.

I fabricated all three of my fire pits.

If you had used Vinyl Sheet flooring in the bathroom, going 3 inches up the walls with a metal top cap on the edges--you would not be having this problem.If you put hard to fix, delicate things in a rental you are probably going to have issues down the road.Maybe to be competitive you need to use a different type of floor, but finding something waterproof for a bathroom--that can be fixed easier, seems like a good move.I mean if a water from a dog dish in a bathroom ruins the floor--that (to me) seems too delicate for that area.
