Great Purchase

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.

Great small sink

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.

Beautiful sink!

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

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.

Great style

from Charlotte, NC – Verified Buyer

We have not installed the sinks yet, but we were very please with their appearance and quality. The style was exactly what we were looking for. We just selected a grey color for our vanity and know that the sinks will look amazing when installed.

Looks Great!!!

from Stuart, FL – Verified Buyer

The sink has a nice look and is the perfect size for using in areas that have limited space. It is on the smaller side but big enough to be perfectly functional. The inside shape of the bowl is attractive and unusual so you don't see it in every bathroom.

Great choice for smaller spaces

from REGO PARK, NY – Verified Buyer

We purchased 2 sinks for our master bathroom. We have a limited countertop space and were looking for something that will fit our modern bathroom. We decided to go with undermounted sinks as it makes the countertop space looks less crowded and more polished. Great choice.

Two bathroom sinks

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.

Stylish, Well-crafted Sink

from New Orleans, LA – Verified Buyer

I love this sink! It's large enough to hand wash a few clothes and yet it still looks stylish. Very good workmanship.
