Looks great installed

Undermount, so we wipe the counter straight into the sink - no rim to catch anything. At 16 by 16 inches it fits our vanity top. The transitional look works in our bathroom - not too modern, not too traditional. Part of our powder room update, and we're very happy.

Two weeks in and no complaints. Undermount, so we wipe the counter straight into the sink - no rim to catch anything. For the price, I expected less. Exactly what we wanted.

Two weeks in and I'm not thrilled. Just not the look we were going for - it didn't suit our bathroom. A bit bigger than I expected - double check the measurements first. The white is a bit brighter than our older toilet - not a perfect match. Not the cheapest, but fair for the quality.

Would buy again

Size is just right - we measured and it fit. Cleans up easily - soap doesn't stick. The instructions were easy to follow for a DIY install. Less than the local stores wanted for a similar undermount sink. My only complaint: undermount needs a stone counter - keep that in mind.

At 16 by 16 inches it is the right size for our vanity top. The round shape looks great.

Really happy with it

Cleans up like new - toothpaste wipes right off. Good value for the quality. The transitional look fits in our bathroom - between modern and classic. The cut-out template made our fabricator's job easy. It's cUPC certified, which our plumber asked about. Really happy with this one.

Good but not perfect

Comes with an overflow, which was a must for us. One small thing: the white is slightly cooler than our existing fixtures - not a perfect match. Good, not perfect.

Standard 1.75 inch drain opening, so our drain fit no problem. Double-fired glaze feels thick - still looks brand new. Fair price for the quality.

Two weeks in and it still looks great. The cut-out template was spot on. Undermount needs a stone counter - keep that in mind.
