Hello!
I've got a small sink make from a plain white ceramic salad bowl. It was mounted on a counter, and a hole was cut through for a chrome drain pipe. Looks nice, but there is a problem. The bottom of the bowl -- about 1.5 inches radius beyond the edge of the drain pipe -- is pretty much completely level, and worse, the metal drain pipe lip is raised about 1mm above the level of the ceramic. Hence some water never drains (horrible for toothpaste, for example).
Replacing the sink isn't an option -- is is smaller than I have been able to find commercially, and a custom (pottery) sink costs a bit too much. The space it is in is not amenable to standard sinks, and we like the exact size and dimensions of the existing sink anyway.
Here are three possibly bad ideas. Can anyone comment or offer a better suggestion?
I could try and grind out a depression for the drain lip to sit in, but no idea how I could do this reasonable well.
Fill up the bottom 1mm of the sink with "tough-as-tile" epoxy paint or similar (and maybe paint the rest too, to make sure the color matches). Do this in 2 or 3 layers. It would still leave a level area at the bottom of the sink, but at least no raised lip. Can it go on this thick? Will it crack?
Lastly: do the same, but let it cure while sitting on a motorized potter's wheel type contraption. The spinning would push the epoxy outward, leaving the bottom sloped to the middle. This seems just unrealistic most likely.
Thanks in advance
