I am remodeling our half bath and got this 20″ Undermount Sink for our new vanity. I am still waiting on my granite vanity top to arrive so I haven’t had a chance to install this sink yet. The instructions booklet that comes with this sink is amazing. Nowadays, it seems like instructions have been getting worse with new products, but the Installation & Care Guide for this sink is detailed, very intuitive and provides specific installation instructions. It takes the guess work out of installing this sink which is a huge plus. The rectangular design provides ample interior space for all your washing needs. The sink feels very solid and the finish / glaze on the inside of the sink is well proportioned and looks great. It is easy to wipe clean and appears very durable. I was a little concerned at first about the small openings on the bottom of the sink, see the my photos. I was not sure if these openings affected the overflow drainage of the sink, so I did a water test and all of the water that flowed into the overflow drain went directly into the main drain. While the openings on the bottom of the sink are not ideal, they do not affect the operation of the sink in any way. Since it’s on the bottom, you will not notice it once installed and it will not affect the sink or it’s appeal in any way.

My wife already loves this sink. I had planned to upgrade my bathroom with it, but that plan may be changed. It’s a roomy sink, having so much more usable space than an oval sink. It’s very heavy for it’s size, as is appropriate for this shape of sink. It also has a good depth of roughly 6 inches. It is nice that the drain hole has a good quality chrome bezel. I did expect that the pictured drain and some attaching hardware would be included. Those things are quite easily sourced.

I prefer undermount sinks like this one because they are so much easier to clean the countertops around the sink. This is a really well made ceramic 20” sink that feels really strong and thick. Some ceramic sinks seem thinner and prone to cracking. Not this one. Comes with an instruction booklet for installation and QR code you can scan if you need additional help. Of note sink does not come with any mounting clips so you will need to pick up 6 of those for a proper installation. You can use galvanized hanging straps but the sink clips with silicone chalk seal is the preferred method.
