Kohler K-2905-4 Reviews

Rated 1 out of 5 by from Buyer beware Product was delivered surprisingly quickly and in perfect condition. However... I purchased this sink (and one of another color) to replace Kohler sinks of the same size that were 25(?) years old. The original one was rusted so badly underneath the mounting surface that the rust was actually forcing chips and chunks of porcelain off of the casting around the outer edge, lifting the sink off the Corian vanity and rust-staining the surface. (It had gotten so bad that I could no longer hide this defect with caulk.) I decided to replace it thinking perhaps it was never installed properly and a new one wouldn't have the same problem. The new ones have no porcelain wrapping underneath the mounting surface or inside the drain either. Their website says to use silicone caulk when seating the new one. Fine ...but you would think Kohler might have learned to protect the cast iron in the drain at least so that the rust wouldn't eventually migrate up around the drain stopper (as yet ANOTHER one of their sinks is doing in our home and we have yet to order those). Went online and read a helpful post that recommended painting the underside before installing. EXCELLENT idea!! So I did that and also painted inside the drain. Fingers crossed... Another issue: Years ago when the original Kohler products in this bathroom were installed (tub/shower, toilet, and sink), the colors were much darker than is available now. We chose innocent blush in the hope of matching the original pinkish-mauve sink we were replacing. Not even close. So keep in mind - this product has only the slightest pinkish hue to it. (We were actually fine with that.) Otherwise, the quality of the VISIBLE finish is excellent and I am optimistic that going BEYOND following the manufacturer's installation instructions will yield good results for many years.

Rated 1 out of 5 by from Don:t buy After 5 years this cast iron sink rusted around the underside of the rim and around the drain hole. When Kohler was contacted they stated it must not have been sealed properly and gotten wet. Duh!..

Rated 5 out of 5 by from Perfect Replacement This sink is a like for like replacement for a 10 year old sink which was cracked and rusting around the drain. Happily, it is the same type of sink. I like the style, and it is a perfect fit.I was also happy with the quick delivery, and price.

Rated 5 out of 5 by from Excellent order feedback Your rep was so courteous and helpful in finding one of the last out of production bathroom sinks to color match our out of production stool. It's a real pleasure to work with a company with employees that take the customer's requests as a challenge to be solved rather than dismissed. Thank you for your assistance in redoing our bathroom.

  • my sink dimentions are 20" x 17.5" will this replacement will fit

    A. Possibly as this is a drop in model & the dimensions are close. The best way to tell is to look under your sink & measure how large the cutout hole your current sink is in to be sure that this one will have adequate space to rest the lip of it on. The basin dimensions are 16" x 11" so the cutout hole would also have to be large enough to accommodate that size basin. Please let me know what questions you may have; I am happy to help!
  • What is the difference between K2905 and K2906? I want to replace an existing K2904

    A. The Kohler K-2905-4 is depth (2905 - 8 3/4" and 2906 - 8 7/16)and very slight detailing differences.
  • Does this come in 8 inch openings for the faucets?

    A. You would order Kohler K-2905-8 for the equivalent model that works with 8" centered faucets.
  • does the sink come with brass or chrome fittings on the bottom drain and the top overflow drain?

    A. The Kohler K-2905-4 doesn't come with the pop up, that usually comes with the faucet that you order so that it matches the faucet.
