Standard fit

Standard 1.75 inch drain opening, so a regular drain fits without adapters. The round shape is exactly what we wanted. Undermount, so we wipe the counter straight into the sink - no rim to clean around. Cleans up like new - soap wipes right off.

The transitional look fits with our bathroom - between modern and classic. The white glaze is bright and goes with everything. No regrets.

Less than the local stores asked for a similar undermount sink. Double fired glaze is tough - still looks brand new. The white glaze is bright and looks clean.

Just installed it and so far so good. The instructions are easy to follow. Cheaper than the big box stores asked for a similar undermount sink. Cleans up like new - toothpaste doesn't stick. Only downside: size is fine; just a touch bigger than I expected.

Decent

Compact 14.3 inch size is perfect for our small bathroom. If I had to nitpick: not the look we were going for - it didn't suit our bathroom. The white is slightly brighter than our older toilet - not a perfect match.

The cut-out template was a big help. Small 14.3 inch size is just right for our powder room.

Picked this for our bathroom reno, and it's perfect. The round shape is exactly what we wanted. It's cUPC listed, which our plumber asked about. One small thing: smaller than I pictured at 14.3 inches - ok for a powder room, tight for washing your face. Not the cheapest option, but worth it.

Six months in and still love it. Undermount, so we wipe the counter right into the bowl - no rim to catch anything.

The cut-out template was spot on. Double-fired glaze feels thick - no stains so far.

Part of our powder room update, and it's perfect. Size is good; just a touch smaller than I expected.
