  • Covered under Kohler's limited lifetime warranty
  • The distinctive, modern design of the Vault sink lends a contemporary vibe to any kitchen

Kohler K-3839-4 Reviews

Rated 2 out of 5 by from would not order again I love the 60/40 split and the lower divider. The finish shows every spot so having it looking beautiful all the time is not easy to do if you are using it. Also the very angular design of the sides meeting the bottom is not easy to wipe down. If it had just a small curve it wuld be easier to clean.

Rated 5 out of 5 by from Kohler Vault Smart Divide SInk SInk is so cool and sleek looking. Adds a contemporary feel for those of us who have a top mount sink.

Rated 5 out of 5 by from Modern, professional quality sink. A professional grade kitchen sink with a clean, contemporary look. Love it!

Rated 5 out of 5 by from Great sink! and great companny to buy from! I LOVE this sink! It is beautiful to look at, as well as functional. I don't think I could design a better one. I like having a big bowl to wash dishes in, and a smaller one to rinse or drain the dishes. The smart divide barrier is high enough to allow you plenty of water in the bowl, but low enough to let you fill the entire sink(s) if necessary to have the feel of one big sink--great for Thanksgiving dinners, or other special occasions where you have big pots and big platters that need the room. I did get an additional stainless rack for the smaller sink also,and I enjoy having that. I don't obsess about plonking anything down. I have a rental property and I will probably buy this sink for it, as well, if I have the room for it.

Rated 3 out of 5 by from Nice but... I like this sink a lot, very spacious, deep enough and sleek design. However, water tends to accumulate still on the sides and corners and cause unsightly orange stains, that is luckily easily removable with Bar Keepers friend.

Rated 5 out of 5 by from soooo functionable Never been happier with a sink. Deep enough to wash a lobster pot. Great with a small side and a large side including a drying rack. I don't splash water all over the counter when washing large pots. We cook alot and I feel like I have an industrial kitchen sink but it is still beautiful and goes with my great looking kitchen.

Rated 5 out of 5 by from Suitable for large pots.. Low height of divider wall and longer depth makes it suitable for washing large dishes, utensils. The raised grill keeps everything off the bottom of the sink.

  • Is the right side of the sink larger or the left? The picture makes it look like the right is bigger which is what I want but the dimension guide says the left is larger

    A. The Kohler K-3839-4 has a 13" basin on the right side. The right basin is smaller.

  • is there a dish drainer that sits on the top of one of the sinks for this model?

    A. The Kohler K-3839-4 comes with the Basin Rack for the Large Sink Basin, there is an optional Basin Rack for the Small Sink Basin which is Kohler K-6647. Kohler does not offer any racks that sit on top or over the sink itself, only within the basins of the sink.

  • Can I get this sink with the small side on the right instead of the left?

    A. The Kohler K-3839-4 is only available in the configuration shown here.

  • Does it have sound dampening? The tech specs says it does but another comment on a similar Kohler vault sink says it does not

    A. All Stainless Steel sinks made by Kohler have sound dampening. It is a pad that is put on the outside of the basin.

  • For u;ndermount installation can the sink be drilled for a 5th. hole to the left?

    A. A skilled plumber or contractor should be able to drill a fifth hole, however it would void any manufacturer's warranty on the product.

  • Is the K3996-4 available with the large basin on left and small basin on the right?


    Unfortunately the K3996-4 doesn't come in that configuration.
