How much does it cost to retile a shower?

A good estimate rule for a price of most tile jobs is that you add up all your square feet of tile you need and then figure the cost of all the material it will take and then X (times) it by 2.5 for someone to supply and install it. If you are supplying the materials then after you times it by 2.5 then minus your material. Some tile layers will charge extra for corners and edges so it all depends where you live and what contracting company you use. If I was to have someone put tile in my shower I would have the contractor supply and install and that way they can warranty all of it if you have problems with it.
