KOHLER 4108-96 PureWash E750 Elongated Electric Bidet Toilet Seat with Remote Control, Bidet Warm Water with Dryer for Existing Toilets, Biscuit

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.

I thought I might be a bit insane for spending this much on a toilet seat, but it has been totally worth it. There are much cheaper models out there, but I already had a Kohler Highline Classic toilet (in white) that I really like, so I figured another Kohler product on top of that would be a good decision. The reviews were good, the price was high (but no where near the MSRP thankfully), but it worked out.Installation was pretty simple as far as attachment to the toilet. Their recommended placement of the electrical outlet seems odd based on how long the power cord is. It would have been a lot more work to put my outlet on the left side, but thankfully I did not have to. The cord was more than long enough to reach under the bowl, over to the right side. I was able to extend power from a convenience outlet almost directly above. If it had been placed on the left, I don't know what I would have done with all the excess cord. I think my install looks very clean and professional.The remote control looks very nice, but the wall mount mechanism seems very loose. The part attached to the wall is secure, but when you slide the dock down on it, there is too much play. There is nothing you can do about it really. I would have preferred through-holes and some caps to cover the screws. It does appear to come with a bracket for use on ceramic walls, but there is no mention of how to use it in the manual.Speaking of the manuals, they are sufficient, but I think the user's guide could be a bit more explanatory on some of the functions, like how the deodorizer works.The dryer function is an exercise for the patient. Don't expect it to have your bum ready for your underpants any time soon. So far the pulsate and oscillate functions have not "missed" anything, so I am down to just a couple of squares of TP to dry off. This should extend my existing stock of TP many times over.It is nice to get off the toilet and feel clean. Really clean. That alone is worth the price of admission. All the parts look and feel of good quality, so I hope this lasts. There is a chart on the Kohler website that will tell you how they expect the fit and finish to look on their various models of toilets. Mine had only 2 dots (3 is perfect, 1 is not good), which means it will fit fine, but not really match the style of my Highline Classic. I think it looks fine.

The water heater needs electrical power.I like the heated seat and night light.Exceeds my expectations.I had mine installed by a plumber.
