I bet you are referring to the Home Depot granite top at 31 inches. I had the same problem. The first counter top worked great in my hall upstairs bath - was the 41 inch or whatever that size was. Powder room was like yours though - my vanity butts up against the wall and is 30 inches. Would not work for me b/c if I allowed a 1 inch overhang on the side, I found the bowl to be off center. May not be noticable in your room but it was in mine. the sink was not even with the middle of the vanity. Someone did post a link though about how to use a wet saw and do it, etc to shave off the extra 1/2 inch or you can take it to a granite yard and have it done...

HB, I know that seams can provide tight angles (because then there is no stress point) but we aren't looking for that sharp of a corner. I just wonder what the generally accepted interior radius without a seam is, and if 1.5" is considered "normal" in the fabrication world. Ideally, we'd probably prefer something like 3/8" or 3/4."

Yes, I will have the standard 1 and half inch overhang and I will use a standard one hole faucet in the center. I understand there's a half inch difference in the counters but my question is- should that half inch make it completely out of the question or should we find a way to make it work as is? That's why I was curious as to what everyone else's measurements were. These counter tops will be our only counter tops for a long long time, so I'm really worried about installing the 16 inch sink they're wanting- It's just so small and I'm so worried I'll absolutely hate it. I've never loved the idea of a stainless steal apron front either but if we went that direction, how are they usually mounted? Would we need to build some kind of brace inside the cabinet?

Need bigger hammer.
