Downstairs Bathroom

The vanity is in, the ceiling has been patched, the old blind is gone. These are the positive things. Yippee.
On the less positive side, the shower has yet to be caulked, the new wood blind won't be here for "two weeks" and the tiling has hit a bit of a snageroo.
Although the tile showroom assured us we could build up the specially modified thinset to make it flush with the existing tiles, they didn't tell us it would take a few attempts, many hours to allow the thinset to set up and the patience of several saints to arrange the glass mosaic, watch it slide off, catch it, wash the thinset off, re-attach it, watch it slide off again and repeat these steps until you just want to rip off all the tiles and replace them with beadboard that you just staple to the walls.
The handy tiler guy says we are not defeated yet and he will attempt to fix it while we are vacationing in Tennessee. If he's successful he'll then grout it and finish the caulking. He didn't say what would happen if he wasn't........
