Customer Questions & Answers

If the Kohler toilet model #K-3658-47 does not come with a toilet seat, why is it shown with one when ordering on line?

Almost all toilets are sold without the seat. It's just common practice. Look around on this site and you'll see. It's not just Kohler.0

The technology for these toilets has advanced and the toilets are quick to fill and quick to flush. We are working on replacing all of the toilets in our house (3) with this wonderful product.

Niether of the KOHLER toilet sets had a toilet seat and thus I had to order separately and drive 50 miles round trip to pick up the toilet seat from Home Deport in Grand Island and the other seat was sent to me. Your information online is very misleading for it shows a toilet seat. Much to my amazement, no toilet seat came with the ensemble. Also, I had to pay an additional amount to obtain the seat.This is very misleading advertising for no one informed me there was not a toilet seat with the ensembles ordered from Home Depot. I should be reimbursed for that toilet seat cost for both toilets.

Arrived in PERFECT condition and were both very easily installed. The existing white toilets clashed unbelievably in both the guest bathroom and a very odd configuration in our master bath in a home we recently bought. Gnashed my teeth endlessly about how to solve the problem, and then viola! Black toilets. They completely disappear into the background, don't clash with the tile, and flush like magic. With black toilet seats these are the BOMB!

Biggest problem was that 1 of the 2 toilets ordered arrived, delivered by UPS, in shattered condition. In addition there were no signs on the boxes indicating "Fragile"! That might have been helpful.
