I live in Missouri and want to replace my shower walls in one of my bathrooms because they are tile now and beginning to look very bad. I am not a do it yourselfer and I don't want to spend too much money! CAN ANYBODY HELP!!

They make pre-fab shower inserts that are pretty easy to install, you can find these at Home Depot / Lowe's. Other options would be re-tiling or re-grouting the existing tiles. I just re-did a shower and bought a new pre-fab pan then put cement board up and tiled the walls, it was pretty easy and not too expensive but took some time.

Let's see, you are from Missouri (show me), you're not a DIY and you don't have money. Why not fix what is wrong with the existing tiles. Ceramic tile surfaces do not deteriorate but they can get scum and mildew stains so tell us what with your tiles. What makes them appear unsatisfactory to you and maybe we can make them look better.
