About a year in and no complaints. The cut-out template was spot on. Cleans up easily - toothpaste doesn't stick. Size is fine; just a touch smaller than I pictured.

The white glaze is crisp and goes with everything. The round shape softens the look. Price was right for the quality. Picked this for our bathroom reno, and we're very happy.

Colour a bit off

The instructions are easy to follow. The white is slightly cooler than our existing fixtures - not a perfect match. The price was a bit more than I wanted to spend.

Great shape

The round shape looks great. My only complaint: the white is a bit cooler than our existing toilet. Not the cheapest, but worth it.

Really happy with it

Comes with an overflow, which was a must for us. Cheaper than the local stores asked for a similar undermount sink. Undermount, so we wipe the counter straight into the sink - no rim to clean around. One small thing: size is good; only a bit smaller than I pictured.

Great purchase

Standard size drain opening, so a regular drain fits without adapters. If I had to nitpick: size is fine; only a touch bigger than I pictured. Would buy again.

Standard 1.75 inch drain opening, so our drain fit no problem. Would recommend.

Has an overflow, which was a must for us. Double-fired glaze is tough - no stains so far. It's cUPC certified, which our plumber asked about. The cut-out template was a big help. The transitional look fits with our bathroom - between modern and classic.

Standard 1.75 inch drain opening, so a regular drain fits no problem. For the price, I expected less. Instructions were clear even for a first-timer. Size is exactly as listed - measure and it fit.

Well made

Cleans up easily - toothpaste doesn't stick. It's cUPC certified, which our plumber asked about. Price was right for what you get. The white glaze is crisp and matches our toilet and tub. The round shape is exactly what we wanted.
