Works Well and Fits Our 1.6 gpf Kohler K3466 San Raphael One-Piece Toilet !
Wife wanted a bidet seat for several years. Each time I researched, I was scared off by the price. Finally convinced it was time, I was really challenged to find a seat that would fit our Kohler, San Raphael, one-piece toilet. Even Kohler support said they didn't have one to fit. But, one of the Kohler, on-the-phone salesmen, Lucas, sent me a follow-up email with a Kohler, 1.6 gpf, San Raphael cut sheet that recommended the K-4108 (PureWash E750 - which is the new name for the old Kohler C3... Wife wanted a bidet seat for several years. Each time I researched, I was scared off by the price. Finally convinced it was time, I was really challenged to find a seat that would fit our Kohler, San Raphael, one-piece toilet. Even Kohler support said they didn't have one to fit. But, one of the Kohler, on-the-phone salesmen, Lucas, sent me a follow-up email with a Kohler, 1.6 gpf, San Raphael cut sheet that recommended the K-4108 (PureWash E750 - which is the new name for the old Kohler C3 230) Elongated bidet toilet seat. At almost $900, (we have a biscuit-colored toilet and chose the more expensive, biscuit colored seat to match), it was a hard bullet to bite but I ordered it. Showed up 3 days later. Took the original seat off and set the new bidet seat on the toilet and it fit !!! Only took about 20 minutes to fully install, adjust, and plumb but it fit and no leaks. Now, getting it to work was a separate challenge. Plugged it in and installed 4 AA batteries in the remote base. When I pushed on the buttons on the seat, the lights came on but nothing happened inside the toilet. Reread the instructions, pushed the buttons again, attempted to link the remote, but still nothing like I expected. Unplugged for 30 minutes, plugged back in, tried everything again and still no expected response. (The seat would trickle water like it was cleaning the wand and then nothing. Occasionally I would push the fan button, and the wand would come out and spray until I pushed stop. The deodorize button did work reliably.) Sat down on the seat, tried everything again, same results. Discouraged and it being a Friday evening, I just left it alone, plugged in, figuring to call Kohler support Monday morning. Woke Monday morning and the wife told me that she had successfully used the bidet seat Sunday night. All buttons worked properly on both the seat and the remote. I tried it that morning with the same, successful results. I guess it just needed to sit there and think about things for a while - but more likely, the remote needed more time to fully charge off the batteries. Bottom line, if you have a Kohler, 1.6 gpf, one-piece, K-3466, San Raphael toilet, this K-4108 Bidet seat fit and works for us. Best as I can tell, it is the ONLY bidet seat that will fit this toilet - and I checked with several on-line bidet shops - in addition to Kohler. I'll try to submit a follow-up in about 6 months.



This can't be a Kohler product
Purchased this Bidet seat to install as part of an extensive remodel. the entire house has only Kohler products because, while more expensive, we wanted something high quality that would last. I can't believe the way this was engineered and yes, I chose to look past other owners' comments about the plastic thread issue. My mistake. Everything about this unit seems up to Kohler standards EXCEPT the cheap plastic piece where the water line connects. I should have suspected a problem when a) it was... Purchased this Bidet seat to install as part of an extensive remodel. the entire house has only Kohler products because, while more expensive, we wanted something high quality that would last. I can't believe the way this was engineered and yes, I chose to look past other owners' comments about the plastic thread issue. My mistake. Everything about this unit seems up to Kohler standards EXCEPT the cheap plastic piece where the water line connects. I should have suspected a problem when a) it was plastic and b) it is not secure (wiggles around.) After all the electrical was done, new KOHLER toilet installed the LAST part, literally, 5 minutes from being done, the connecter leaked. Bad. Took extra precautions because it appears so cheap to only hand tighten but had to use a small wrench to go 1/4 turn past hadn't tighten to try to stop leak. (BTW, the threads are recessed so no opt to use thread sealant tape as a solution.) BOOM the piece broke. Turns out it is a 1/4 inch piece of plastic that takes all the torque when you tighten. Who designed this garbage? No conceivable way to fix the issue. So disappointed in Kohler for producing this piece. Had to uninstall the entire unit (unusable) and now I am at the mercy of Kohler warranty work to try to save the $1,000 investment. I am beyond frustrated with this company.
