I am thinking about renovating the bathroom and replacing all the old things there. First of all, I want to replace the bathtub as it looks a little shabby.

This would be quite expensive though. Have you seen the prices? They give me anxiety sometimes. I prefer reglazing to it. It's less expensive and if you do it properly then bathroom gonna be looking as good as new. Oh, and if you don't know how to do it then you can check out Tile Reglazing Queens. They will do this work for you and will make your bathtub as good as new.
