It might be helpful to provide your tenant with a "Zip It" tool (around $4 at most big box stores) to use to remove hair clogs from bathtub drains.Gail

I have a tenant that just moved into one of my rental properties (a condo) last month and now water damage has occurred from the upstairs bathtub that has caused water to come through the ceiling that is visible from downstairs. 

Raw sewage started overflowing out of the toilets, sink, bathtub and all over the floor. 

The guys come with all the electrical tools and start to deliver the build material.During the rehab we had all outside cleaned up, trees trimmed, painted inside and outside, new laminated floors, painted the cabinets, replace countertops from wood to granite, new vanishes, new bathtub, replace all the doors and windows, new ceiling fans, and we removed the garage wall growing the living room area, changed the access to the roof, full service in the Hvac, etc.

I tiled the floor and bath tub surround, I put in new drywall and installed a new mirror (I chickened out with the new vanity and toilet and had a pro install those...

It would not have been possible if only one of us was willing to put up with the disruption, removal of bathtubs, sinks, electric upgrade and on and on (not all at once of course).

For rental I was thinking about just  glaze the bathtub and wall tiles and change flooring. 

And great job on that bathtub!

(before we moved in, we had one plumber quote us a price of $900 to get a bathtub drain fixed -- something a friend of ours and I later DIY-ed for $80 in parts, and 30 minutes of labor.) 

The property had been vacant for ten years, took two years to rehab -- I wasn't surprised that a large family putting it to the test revealed a problem or two (nevermind the building passed every inspection, or that the contractors missed some basic stuff like no hot water running in the master bathtub.)
