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?

Asked by: bob1089
It is ridiculous that it is not sold with a seat! I was getting ready to buy one. I am not going to spend more time to figure out the size, color match etc to buy for a toilet and getting it wrong is a disaster...... Get with it, or ask less money if this continues. Back to looking at other toilets.

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.

Grateful for the perfectly sized seat that was suggested. This is a 2 piece product which makes for easy installation. Looks great in my 1930's pink and black original bathroom. Very pleased with every aspect of this sale. Thank you. Highly recommend.

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.

Rated 1 out of 5 by from Ineffective at flushing solid waste The supposed effecient use of only 1.28 GPF is misleading when you factor in the number of times this toilet clogs on solid waste and then the number of flushes combined with a plunger to move the solid waste on. With several flushes requred to move on solid waste in combination with a plunger this actually uses more water than our previous standard 1.6 GPF toilet. This toilet clogs on solid waste regularly (almost daily with regular use shared by two people) and unclogging it with a plunger is difficult because of the specially formed flush channel in the bowl that makes it difficult to get a good seal around the bowl drain. After only a month we are getting rid of this toilet because of the constant frustration of it plugging up.

Hello Home Depot: My handyman picked up the toilet from your store in Union, NJ, and the toilet was broken. So I have to reorder it. This has taken way too much of my time. I am waiting to see if I have been reimbursed before I reorder it. Simone Wegge

Rated 5 out of 5 by from KOHLER HIGH TOILET Oh how nice to be two inches higher. This toilet is amazing. The flush is fast and quiet and does the job immediately. It has a classical design and looks great in the bathroom. I highly recommend this toilet.
