I have 2 bathrooms in my home. They both have the run-of-the-mill tub/shower enclosures in them (fiberglass tub/shower combos) and are single piece units. What The LOML wants me to do is to put up a nice tile and grout over the top of each tub/shower enclosure. These surfaces are painted sheetrock. I didn't build this house so I don't know if it has the typical "green or blue" drywall installed or if they cheaped out and put up standard drywall.
My question is this: Can I put up tile over the painted sheetrock/dryall?
I don't want to have to rip out all the drywall from over and around each tub/shower enclosure but hope it's as easy as roughing up the painted surface above each enclosure, putting down a mastic / thinset, apply tile, let dry, then grout.
I'm not a tile guy but I know it's not all that hard for someone like me who's done a little of everything construction related.
Advice, tips, pointers welcomed.
