So someone is optimistic and I’m going with what most of them are saying.

I’m not optimistic about the prospects as I’m getting many requests for additional money.

I think a key part of building wealth is being paranoid and optimistic at the same time.

If the repair process requires painting the whole thing, which it may need to look good- I'd optimistically put the lifespan of a professional/specialized 2-part (epoxy or urethane) tub/surround (or tile paint) etc- paint job, with above average prep work at ~3 years.. a "high quality" tub respray like this will cost just as much as a brand new tub, and touching up/blending a spot repair is specialized, expensive work as well. but yes I agree with the other replies either way -(unless, *perhaps* there is already easy access from behind etc to get to the repairs and inspect flooring etc without taking tub out)- it makes sense to rip it all out so you can address any potential water damage, and overall there is no reason the resulting new unit shouldn't cost aprox the same ballpark as the repairs .. and new of course will look much better with a much longer lifespan. 

Overall, for the first full year we are happy and optimistic.
