I have an old house built in 1929 in Minneapolis, Mn. I need to replace water damaged rotted basement bathroom floor(toilet and shower leak another story). Current floor is 2" by 4" sleepers set on concrete with either treated plywood or cement board(not sure haven't pulled up yet) and vinyl on top. I want to replace the floor but I need to do it on the cheap because I'm 40k undervalued in this house. I'm also assuming the original cement floor under all this is in rough shape.
What are my options?
