## Questions & Answers

**Q: what is the actual cut out hole size for this sink?**
A: actual cut-out in countertop for our overhang/under-mount installation is 10.5 inches by 15.5 inches.  Agree that flush-mount installation probably would not look very good.

**Q: Is this sink bright white?  If not, would it contrast too much next to a Kohler white toilet?**
A: The sink is decidedly white.  We have it in a small powder room with a Kohler toilet, pure white wood base and ceiling trim, and "snow" granite.  The whites all go perfectly fine together.

**Q: Is there puddeling on the bottom near drain or does the water run smoothly down to drain, afraid it look very flat in picture and water will not drain**
A: I can't say anything bad about this wonderful little sink! There is no puddling at all it drains perfectly. I installed a pop up drain from Amazon in it as well.  The finish is perfect, the shape is very modern and I am very happy with it. Now that I ordered it I see it in remodels on TV and in photos all the time! It is perfect for a narrower space like my bathroom which had the original cabinet in it that was built in 1950. I had a new one built the same depth because that was all the space would allow and this sink looks fabulous dropped into my new quartz top!

**Q: will this fit a 18" d X 36" L cabinet**
A: my cabinet is 20 deep...I am not sure that 18 would leave enough room for the faucet etc...I used this sink in a tiny bathroom w/ quartzite on top.  Nice sink though.  I would ask your cabinet maker and counter top fabricator.
