Customer Questions & Answers


What are the exact exterior dimensions (w x l) for both the 4" and the 8" Willamette pedestal sink basin?
Asked by: Contractor
We put a man on the moon, but we can't get the dimensions of a sink. So, I went to my local Home Depot and measured their floor model. It's 25.5" wide (left to right as you face it), 20" long (how far it sticks out from the wall), and standing on the pedestal the top surface was 35.375" from the floor.

Asked by: Dino
Hi Dino, I'm Tiffany with Kohler Co. I'm happy to answer your question about the Willamette pedestal sink. This is a two piece model, the pedestal and the basin. Thank you for choosing The Bold Look of Kohler.

I need a pedestal sink that drains through the floor not the back.can this be done on this model

Can you recomend a model for my need.It cant be wider than 18 inches and not too deep front to back. thank you.
Asked by: jim
It cannot drain straight through the bottom of the pedestal. The drain hole would need to be between the pedestal base and the wall. The bottom of the pedestal has a small hole to mount it to the floor, but not to receive a drain line, not to accomodate a p-trap.

What hardware should I buy to install the sink aside from faucet?

Asked by: Maria
You will need plumbing extensions. You will need supply lines for your sink and a p-trap connection to your drain (assuming both are in the wall and not the floor). For mine, supply lines needed to be at least 12" and the p-trap needed an extra 4" from the sink drain to meet the p-trap adapter.

Rated 3 out of 5 by from This is a beautiful pair, to be clear, but there are things that a buyer should be aware of. Fir... This is a beautiful pair, to be clear, but there are things that a buyer should be aware of. First, the base is not perfectly flush/flat on the bottom and it is raw finish, so it will scratch your floor without some barrier between it and the floor as you maneuver it into place. Second, there is no positive "lock" between the sink and the base, so whether you have them perfectly positioned; one on top of the other, is at the mercy of your best guess (no guide peg/hole, channel, etc..). To that point, you may have to scoot them a bit and you will scratch your floor doing it if you are not careful. The 4" is more expensive than the expandable and is only available online, which is a mystery. Small sink basins are not really suited for spread fixtures and the majority of the fixtures in the store are fixed width. Attaching the plumbing was no problem and the overall install looks fantastic, though I would not trust the sink / base to support any weight because of the lack of positive lock (the 3 lag bolts; wall and floor, mitigate this, but with the bottom of the base not perfectly flat and the fit between column and basin not locked in place, I am not confident that it wouldn't topple under a series of unfortunate circumstances (like a kid trying to hang on the edge...because kids do that). Overall, I'm happy with it, but would like to see a few things addressed to take it from "pretty" to "excellent".

Rated 1 out of 5 by from Poor Sink Casting - Uneven and Blemished The pedestal bottom portion is fine, straight and even. The sink portion however is poorly casted. Specifically the bottom edge/ rim that rests on top of the pedestal is not level. We struggled for a while to make the sink top level, after getting the pedestal plum. We thought that we perhaps had it misaligned, because the last thing we expected was a warped sink. Upon close eye inspection, the warping was visible. Kohlers response to another customer with the same issue (see below), doesn't make sense. Why not just start with a straight, quality made product to avoid having to use the "pads" / "gaskets" at all. I'm guessing these "pads" were included as a 'damage control' fix to save all of their poorly made inventory. I've installed three other pedestal sinks, and have never had these issues, or seen this sort of solution presented. Response from Kohler Product Expert September 29, 2016 Hello, my name is Sarah with Kohler Co. I am sorry to hear your Willamette pedestal sinks had several small flaws in the finish. This is not normal. Could you please send pictures of the flaws to our Customer Service team at This will help us find a solution for you. Regarding the installation, the pedestal sinks should not "sit" on the pedestal base. The sink will mount to the wall and there will be pads between the sink and pedestal. The sink is leveled by the installation into the wall by the hanger bolts. If you have any questions regarding the installation, please email us. We're glad to help! -Sarah B. KOHLER Customer Service

Rated 1 out of 5 by from defect in the casting caused water leaks I believe my sink had multiple defects in the porcelein casting. First noticed that despite the pedestal being perfectly level and plumb when attached to my bathroom floor, the sink top surface sat very far out of level left to right when placed upon it. A large 3/8 inch shim under the left side and smaller one in the front (where the sink meets the pedestal) allowed the sink to sit level when measured left to right as well as front to back. Next, after installing the drain I had a substantial water leak. After contorting myself under the sink and refitting the drain parts multiple times to eliminate any errors during install, I was forced to unbolt the sink from the wall, disconnect the water supply lines and move it to my workbench for closer inspection. I found several defects in the area where the drain pipe's rubber seal mates to the porcelain. The lack of a clean and uniform surface prevents the rubber gasket from forming a clean seal. My career is product development so I understand that defects will occur in mass produced product and some defects will simply slip by QC unnoticed. Will open the next box when going to HD tomorrow for an exchange and will inspect the porcelain casting prior to driving home. Not a bad product, but make sure to inspect the above areas. Hoping I can find a good unit... install was done in a brand new powder room I just finished installing. I'm committed to the holes in my walls, wallpaper and new tile floor specific to this Kohler sink model. A potential large problem if I need to go to an alternate pedestal brand and/or design. One last thing... the supplied pedestal securing lag bolt is too short for anything other than a laminate floor. Drilling thru my new tile and cement board to get to the wood for the bolt to bite, leaves insufficient bolt length. Needed to source my own longer lag bolt to hit the wood subfloor effectively.

Rated 5 out of 5 by from Beautiful Sink This is a beautiful, stylish, oval pedestal sink. It arrived much sooner than I expected. It is rather large for a small bathroom, so be advised. It is "comfort height", which is really nice. I had it professionally installed by a plumber. The wall behind the sink has ceramic tile, and I need to be sureit was done right, with the right tools. I am very pleased with everything to do with this purchase.
