    • Great product and delivery

      Our “granite guy” steered us away from the Big Box stores and suggested we would get a higher quality product at a lower cost. He was spot-on!

    • Great sink!

      This sink is a great choice for any kitchen. We looked far and wide for a undermount 2-bowl sink for our new kitchen. Our cabinet was only 33" and most double bowl sinks won't fit. This sink was exactly what I was looking for - high quality stainless steel construction, nice and deep, beautiful, and great accessories. It was securely packaged and shipped very quickly too.

    • Great price for a quality sink

      Love this new sink, was looking for a heavy gauge sink to fit into a 33" cabinet and this one fits perfectly, loved that the drains were included and the bottom racks, however the plumber could not use the left drain (large side) due to the location of the pipes in the wall. Since the sink is deeper than my old one with the drain also being a bit longer they just would not line up with every thing else (disposal etc) make sure you measure the sink depth with the drain to the location of your pipes or just buy a seperate drain as we did. Love it!

    • Beautiful, high quality sink

      Came upon the Kraus BU21 while researching sinks for an upcoming remodel. The Kraus stainless steel sinks receive outstanding reviews for all of their sink models/sizes. I was looking for a smaller sink format to fit into a 33" cabinet. Other online reviews indicate that this unit will even fit into a 30" cabinet. The sink arrived within 3 days of order. And comes extremely well packed for shipping. Accessories (grids, drains, towel) are a great find for this price.

    • Why did you choose this product?

      • Clients liked it.

    • what is heavier 16 or 18 gauge Stainless?

      • The smaller the gauge, the thicker the steel. 16-gauge stainless steel is heavier than 18-gauge stainless steel.

    • Will this fit a 30" sinkbase cabinet?

      • It should fit because the exterior dimensions are 30 inches long x 19.5 inches wide x 9 inches deep.
