We recently had a bathroom put in our basement. We had the "contractor" (not on speaking terms now as he just kind of disappeared) put in a recessed tiled shelf in the shower. We now have noticed the grout separating from the tile around the edge of the shelf. And it looks like the water is seeping down to the drywall. My question is where do we start? Since the original guy is Mia, do I call a plumber? So distraught over the whole basement anyway as we had water damage awhile ago. Looking for some advice please!

If the guy used drywall in that shower and there's only one technique that has an approved method that allows it (Schluter's Kerdi membrane shower system), your shower was not constructed properly. It's hard to predict how long it will last. People tend to think that tile is waterproof in a shower...in reality, a properly built shower is water tight before the tile is installed. The tile is a decorative and wear layer, not the waterproofing layer! Cracking grout is an indication of movement. Whatever is behind the tile has absorbed moisture and is swelling, or it was just not built strong enough, and there's movement from that (much more likely from what you've indicated that it's the former rather than the later, but it could be both).

There is a site run by John Bridge - his name followed by .com - that may be extremely useful for you. From what I've read there jadnashua's comment above is exactly correct. (I see he's been to a Schluter workshop, too.) You can get advice on the john bridge site. How the heck one find's skillful, honest tradespeople/companies I still don't know. I've paid a lot and I've paid not so much. Have had some very satisfactory work done for decent prices and some awful work done for quite high prices.
