Shower Remodel

Unlike a house there is NO STRUCTURE on 2 of the 3 walls to install tile. You would have to cut out the existing fiberglas and then build wall frames and install either cement board or mold free plywood to adhere the tiles to. Then you would have to build a watertight floor and connect to the existing drain plumbing. Based on what I paid for my house, the glass doors would be $1000 to $1500. Can you post what you were expecting to pay? I would estimate the total cost 10k to 15k. Based on my 42 years as an RV tech and especially 42 years as a Tiffin dealer RV tech. In all those years, I have never heard or seen what you want to do. To take a brand new RV and attempt to do what you want usually costs way too much. What you have experienced is, buying a RV floorplan and find a major part(to you) that does not meet your needs and the usual recourse is to sell and find the floorplan that fits your needs. IT WILL NEVER ADD TO YOUR RESALE VALUE OR RECOUP YOUR COSTS. This is not like a residential remodel. One thing about RV's and Motorhomes, the travel and flexing does not work well when you have ceramic tiles and such installed like a Home. You will experience cracking grout and probable tiles coming loose. Doug
