Wow, hauscat, how'd you manage to dig this thread up? Clearly I forgot about it entirely, as I never did post our "after photo". If I think of it, I'll do it when I get home.
Looks very clean, though I kind of miss that rustic red tile look in our bedroom, and the newly laid tile ended up being slightly more sloped than it had been before, so the screen, which just rests on the floor, wants to tip over. I solved the problem somewhat ingeniously (if I do say so myself) after watching a video of clever uses for those black binder clips. I'll take a close-up shot of that and post here.
If I had realized how bad this would end up looking, and how unfunctional having a painted tile floor would be, I would have just touched up the chipped tiles with a bit of flat wall paint and called it good enough. Unfortunately, it's too late.
So now I'm thinking that we should just have the area re-tiled, but I want something similar to what we had - a basic matte brick red tile - and I don't know where to buy the tiles or who to call to do the work. Do we need special "hearth" tiles, or will any ceramic tile work?
The tiles we currently have look(ed) something like this (this picture is not from our house):
