Hello,
We had this done this summer on the bathroom in our new house. I'd say I'm 85 percent happy with it; we really needed something fast to improve what we had, and this was the most economical option as we didn't want to redo the whole bathroom. The things I like about it are that it looks nice and it's incredibly easy to clean... no more moldy grout! What I don't like is that I think our guy was a bit lazy with taping off the surrounding areas as well as cleaning out old grout so there are areas that just don't look as nice as I would have liked, as well as a few spots of the enamel on our walls (not tiled). If we redid our bathroom in the future with more time/money/energy, I would probably not go this route, though if we decided to try it, I would try a different vendor. We used Beautiful Finishes, because we played phone tag with Aarco for quite a while and it got down to the wire of when we needed it done. Aarco was more highly rated on Angie's List, and probably would be the better choice. We have a lot of tile that includes all the walls that surround our tub, including the ceiling above it; it was about $700 to do all of it, and it was done in a day. I'm thrilled that it's so easy to clean and was much more affordable than redoing the whole bathroom, but if we had had more time before moving, I would have researched it a bit harder to make sure it would turn out well. I would, however, definitely try it for refinishing a claw foot tub, as the results with that look really great!
