4 inches up

Shae was very excited as I decided to remove the rest of the plywood and old flooring materials from the old bathroom floor. It was relatively short work that revealed proof that there had been many water damage issues in past years. 

The floor is quite soft in spots so I will need to pull the floor completely up to repair the floor joists. A level subfloor will be added at that time and old flooring will be mixed in with replacement flooring make a uniform surface. 

We were amazed, but not surprised, as the floor was actually built up no less than 4 inches up the side of the bathtub.
