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?

Asked by: bob1089
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

Highline 2-piece 1.28 GPF Single Flush Elongated Toilet in Black Black is rated 4.3 out of 5 by 51.

The ada comfort height is a big plus since I had spine surgery. It makes all the difference in being able to stand up from bowl on my own. Easy installation, A real pleasure to install, The flushing system is fantastic. Had the bowl for 18 months and flushes great every time. To get an elongated comfort height bowl in black at this price is the steal of the decade. The low flush rating of the bowl is fantastic with great flushes all the time.

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!

Unfortunately, my original purchase of a toilet &a tank was cracked, but Ms. Francine reordered the item and confirmed that I received a replacement tank in good order. Thanks again Ms Francine. ECR.

Rated 1 out of 5 by from Broken toilet. Toilet came I'm with a broken bowl. I wanted to reorder and bring in just that piece. I'm lazy. Manager said no I would have to return it all then reorder. I told him if I bring it all there will be no reorder. He said he understood. So I went to lowes and ordered my new toilet.

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.

We bought the color "biscuit" to be just off-white. and were surprised to not be able to find a matching color lid -- we settled for "bone" lid which was close. If could have found matching lid, would rate 5 stars.

It is comfortable, has a short but complete flush cycle and is beautiful in our grey and black repair/remodel of our home.
