Kohler K-3820-1 Reviews

Rated 5 out of 5 by from Beautiful Sink! Great product....highly recommend!
Date published: 2012-06-12
Rated 5 out of 5 by from Excellent buy Beautiful sink - large working area. We had a conventional two basin sink with curved undersides. This sink takes up more space so be prepared when remodeling - we had to do some adjusting to make the sink fit. Since we have a tiled counter we could not use the undercounter sink, but this one comes close to it. Very satisfied.

Rated 1 out of 5 by from Disappointed The style of the sink is great. It scratches easily, it does not drain well and it always has water marks in it & is tough keeping it looking clean & shiny all the time. Very disappointed. Can't wait for a year and replace it.

Rated 1 out of 5 by from Love it but it scratches so easily!!! I love the design, shape & style but the base of the sink scratches so easily!! You hardly even do anything and it scratches. We have a young busy family and the last thing I want to worry about it is trying to preserve my sink!! They gave us a rack which I didn't use at first but now I know why you get it ... not very impressed... I thought it would be more durable and atleast withstand putting plates in. It also, always has water marks in it & is tough keeping it looking clean & shiny all the time...

  • Will this size sink fit in a 33" base cabinet?

    A. The Kohler K-3820-1 has the dimensions of 33" x 22" so it should fit assuming that the 33" is the width and the 22" is the height of the sink.
  • Is this available with two holes?

    A. The Kohler K-3820-1 is available with different hole drillings. Unfortunately 2 hole is not an option. There is a three hole model available. That model is the Kohler K-3820-3.
  • what basket strainer do I need for this model?

    A. The Kohler K-3820-1 would use the Kohler 8803 basket strainer.
  • Does the sink have a hole for soap dispenser?

    A. The Kohler K-3820-1 is a one hole sink only and does not have the hole for a soap dispenser. The model displayed on our site that does include the soap dispenser is the K-3820-4 that is the 4-hole model.
  • how many basket strainer are required to complete the sink's installation?

    A. The Kohler K-3820-1 requires 2 basket strainers for complete installation.
  • Is the hole of the K-3820-1 compatible with the hansgrohe Aquos (approx 2 yrs old) faucet? Are all the parts needed for installation included in the order?

    A. The Kohler K-3820-1 has a standard single hole installation for single hole faucets. The sink comes with everything you need for installation.
  • What is the opening size needed for this sink. I currently have a sink already installed but would like to replace it.

    A. The opening should be 33" x 22"
  • Will k-6135 basin rack fit this sink

    A. The Kohler K-3820-1 is not designed to accommodate the K-6135 rack.
  • What is the item number for the strainer basket?

    A. The Kohler K-3820-1 strainer basket number is K-8801
  • how do I order just the basin racks

    A. The Kohler K-3820-1 needs the K-6641 basin rack. You can order just that item.
  • Which basket strainer color will match the color of the sink? Vibrant Stainless or Brushed Chrome?


    The vibrant stainless will be the closest finish to match the K-3820-1.

  • Is the included basin rack the same as the recommended basin rack?


    The Kohler K-3820-1 is a two basin sink so you would need to purchase two of the racks that are recommended if you wish. 

  • Is this sink NSF certified?


    The Kohler K-3820-1 is not NSF certified.
