Is a malfunctioning bathtub drain stopper switch normal wear and tear or property damage under broken fixture?

There was a water overflow from the bathtub last year and it leaked through the flooring to the first floor. 

The cracks are on the soap holder portion of the bathtub. 

I just completed my 2nd door (the top half of my duplex), it’s a one bedroom, with a stand up shower (no bathtub), carpeting only in bedroom, and what I would define as a total bachelor pad.

I had the bathtubs and tile replaced, even though they were ok, just ugly...

Also some work inside the house like recaulk the bathtub, fix a window sil, add a carbon monoxide detector. 

Seems steep for what it is.Labor only: $6,300Demolition, new drywall & cement boards installation,Floor tiles installation, Bathtub installation, Vanity & vanity top install.

. $13k in my opinion would constitute tiles, bath tub with surround, new vanity, mirrors, new toilet, paint, trim, and light fixture. 

NEW kitchen with NEW white Shaker cabinets AND quartz countertops, NEW wood laminate flooring, UPDATED bathrooms with NEW matching white Shaker cabinets, NEW plumbing, NEW bathtub, shower and tiled floors, All NEW drywall, NEW electrical panel, NEW electrical wiring, NEW siding, NEW windows, NEW roof, FRESH landscaping front side and back. ...

I am a homebuilder in the Houston area and 140$ per square foot would include finishes such as 10 ft ceilings, calacatta waterfall cabinetry, tile in all of the bathroom walls, freestanding master bath tub, waterproof laminate flooring, 8 foot doors everywhere, etc.170$ per square foot and you start getting into the custom luxury home market.200$+ would include large porch areas and patio upgrades, maybe even a pool.
