Great small sink

Monica from Flower Mound, TX– Verified Buyer

Love these sinks! Looked everywhere for smaller sink without having to pay $300. We bought 2 white sinks for master bath remodel and didn't open them until about a month later. Unfortunately we were sent 1 white and 1 off white but it had the correct box. Anyhow, we called for replacement and it arrived but was a little bigger in size. These were not going right beside each other so the difference in size was not a huge deal. So size was not consistent. Love that these were reversible to have overflow showing or not showing. Love the shape. I am very pleased with this purchase.

Great Purchase

Terri from Apex, NC– Verified Buyer

We remodeled our master bathroom, and ordered 2 of the Ronbow sinks - love them! We purchased a cabinet without a countertop on line, and were able to choose a granite top and had it custom cut for the rectangle Ronbow sinks. They look great! One thing we did was install the sinks with the 3 round holes opposite the fixture. Highly recommend.

Beautiful sink!

Elana from Phoenix, AZ– Verified Buyer– Top 100 Reviewer

Well constructed modern rectangular sink! It has a nice smooth finish and the white is nice and bright whereas so e can read off or dirty. Love the squared corners and the depth is perfect for not splashing and feeling like you are able to wash your face without issues!

Very nice

Catherine from Minnesota– Verified Buyer

We purchased the undermount sink as well as a faucet from your site and both have worked out very nicely. Seems to be a good quality sink for the price. I definitely haven't been disappointed at all.

Two bathroom sinks

Rosie from San Francisco, CA– Verified Buyer

I ordered two sinks for each of our bathrooms and they are great. I didn't want to spend a lot of money on bathroom sinks and with these I didn't have to. They are almost $150 less a piece than the Kohler equivalent and only slightly more shallow.

nice sink

Scott from Williamsport, PA– Verified Buyer

Fits the Ronbow vanity top perfectly, nice clean white color. I mounted with the overflow flow holes at front of vanity so they are not visible.
