Ok step back from the edge of the building, pull the toaster away from the bathtub, hold on a minute before going full "Mad Max" end of the world, it's time for a little reality check.  

That said, there are a few things that we consider excessive that I'm uncertain how to handle:1) The tenant busted a hole in the bottom of the bathtub and did not inform my parents of the damage when it occurred. 

Now that I have the report I see that quite a bit was missed (leak in the main drain line in the basement, water in bathtub is not going out, kitchen sink is leaking, rear entrance doesn't have a step, loose guardrails in the basement and on the upper level, windows not operational).

Otherwise, in three months when he can't make rent, he'll replace a bathtub without you knowing and start deducting this from rent payments.

If you shut off water to a unit the "Water Closet" will not function, and some individuals will continue to use it until it "fills up", and then when that happens use the bath tub as a latrine.

Master bath upgraded, tiles extend up the wall surrounding seamless glass shower and a Spa Bath tub.

There is a normal bathtub/shower in the downstairs basement so at least there would be one bathtub if I did a walk in shower.  

@Howard DrakeIf this is the only bathroom then I would remodel to get a bathtub in there.

The upstairs tenant was apparently not paying attention to what was going on in the bathroom and he let his son overflow the bathtub.

In order for those units to be livable, they need everything from drywall to kitchen cabinets to bath tubs.2 units are 900 sq ft with 2 beds and 1 bath each.
