Hi. Any suggestions to solve this gap between the wall and vanity counter top? The vanity came with a backsplash, which I didn't want to use. Thinking I may have to get a separate 3" backsplash and create a side splash with it, although I hate that look, which is why I tiled to the countertop in the first place. gap seems to big to caulk. Any good ideas? Thanks.
I've always avoided issues like that by installing the cabinet/countertop prior to the tile, and then tiling to the cabinet/top surfaces, but that ship has sailed here.
You absolutely can do something about the gap without using any trim or a lot of caulk. I don't know how handy you are, but.....
If you scribe the back and side edges of the countertop, you should be able to get a whole lot closer to the wall. A gap of 1/16 should be attainable, and then with some painters tape and silicone you should be able to get a very nicely trimmed caulking line.
If you really wanted to make it tight you could remove the tiles that are 'in the way', slide the countertop backward & sideways a bit, and then cut your tiles to where they meet the countertop more cleanly.
For either of these 'solutions' it's important that you have enough overhang on the front and opposite end of the cabinet.
Best of luck in any case!
