We are repainting and updating the den/bar downstairs and I would like a new color/finish on the bar top. I have looked at some of the countertop refinishing kits but they all say to not use on tile. I am not concerned about seeing the grout lines but more interested in a different color. It's only a bar top so some occasional water is the only wear and tear issue and there will be little to no chance of heat or heavy scratching. I have attached a photo of the top so you can see it. Does anyone have any ideas for a low cost refinishing method?
