Our customers say

Customers praise the product for its great size, quality, and attractive appearance, noting it is a perfect fit for small bathrooms and powder rooms. The modern design with clean lines and a center drain is also highlighted. Some reviewers mention a potential issue with the lack of pitch to the drain, which may lead to splashing or pooling, a common characteristic of modern sinks.

The title on the product page reads 18 inch sink which is incredibly misleading. In reading closer the actual basin is only 15 inches wide. To make matters worse, after install there is even less visible. I am now stuck with a 14 x 9 inch sink in my primary bathroom - which looks like a tiny wet bar sink. The picture of the product looks great online but not at all what I was expecting.

What is an Overflow?

An overflow is a small hole in the back of the sink that prevents the sink from overflowing. When the sink is full of water, this hole allows air to circulate to the drain so the water can drain more quickly.
