Thank you for your inquiry. If you are looking for a taller toilet, Kohler recommends looking at the Comfort Height toilets which will be 16-1/2" from the floor to the top of the rim of the bowl. Here are some comfort height toilets: K-3658-G9; K-3887-G9; K-3841-G9 or K-3755-G9.

Customer Reviews

Wellworth Classic 2-Piece 1.6 GPF Elongated Toilet in Biscuit-DISCONTINUED is rated 4.2 out of 5 by 15.
Rated 1 out of 5 by from Often wasting water with stuck Class 5 Valve *Class Five flushing technology is surly not all that it should be, or is made to sound like by advertisers at Kohler. They state water usage to be 1.28 to 1.6 gallons per flush, But after using this toilet for a few months, just my wife and I. The Class 5 Valve started hanging open after flushed, not refilling the tank but allowing water to run unstopped into the bowl and down the drain, until we would hear water running and return to jiggle the handle allowing the valve to return to where it is supposed to seat. I checked for a loose backing nut on the handle, also checked chain from handle to *valve for routing and tightness both seemed OK. This toilet is the most wasteful water user I have come across. I am a Mechanical Contractor and have sold hundreds or more, Kohler toilets, however I would not recommend this product to a single person.

Rated 5 out of 5 by from Good deal Wasn't the toilet I had planned on purchasing but it was on sale at $169 in my local store. The price made it hard to refuse given Kohler's better reputation compared to Glacier Bay and other cheapo models. Installation took less than 30 minutes including removal of the old toilet. Instructions are clear enough for someone familiar with the job but a little sketchy I would imagine for someone attempting his first toilet swap. The wax ring was definitely a lot better than I have seen packaged with other all-in-one items like this. Flushes quickly and quietly. Fills quickly too but then I have very decent waterflow/pressure where I live. I'll probably run back to HD later and pick up two more and replace my other toilets while it's on sale.

Rated 4 out of 5 by from Excellent!!! I absolutely LOVE this toilet. It's a little 'petite', however... it does the job. If flushes smoothly and fills quickly. For anyone who has well-water, this is the PERFECT toilet for you. It doesn't require a lot of water and/or pressure to flush. It's quiet and perfect for a smaller sized bathroom. I give it 4.5 stars - not a complete 5, but that's only because it was a lot smaller than expected and it didn't include the toilet seat. Otherwise a great toilet for the value... Just don't forget to order the TOILET SEAT!!! LOL =)

Rated 4 out of 5 by from Nice Flushing Power, slow refill I really like this toilet. It has settings to use 1.6 gal/flush down to 1.28 but I use the 1.6 option (you can adjust downward to any in-between). It does have a fast flush so you almost think you didn't flush correctly, but don't worry, it flushes. It flushes even the biggest mess down quickly. The only thing I thought was strange was that it takes longer to refill than our other toilet, but it is very quiet, so I think they did this so if someone was in the shower, they wouldn't get the quick temp change. After I first installed it, it did leak ever 5 flushes or so, but after wiping the gasket with a rag, it seems to have seated perfectly and it has not leaked once for over 4 months now. I would recommend this toilet for it's rated 10 Bulk Removal and the quiet refill.

Rated 1 out of 5 by from Worst Toilet Ever Bought this toilet from Home Depot for a bathroom remodel, replaced and old broken toilet with it. It has an extremely weak flush and very slow tank filling time. Also, sometimes after flushing, water leaks into the bowl from the tank. The toilet comes pre assembled so I tought I got a bum toilet and exchanged it for another. Second toilet is the exact same way. It's only good for #1, go #2 and you will spend the next fifteen minutes plunging it. That is also difficult because the opening in the bottom of the bowl is not the right shape for a plunger to make a seal. Save your money and time. Stay away from this toilet.

Rated 5 out of 5 by from Huge Upgrade! After a pipe froze in my house while I was overseas, I decided to replace my three toilets. I ordered the Class 6 Cimarrons (elongated, comfort height, 1.28Gpf), but one of the bathrooms had a height requirement that ruled out the comfort-height toilet, so I went to my local store and grabbed the Wellworth. This toilet, unlike the Cimarrons, comes with a lid, but it's pretty cheap. I would get a Lustra Elongated Toilet Seat, which is a great, solid seat, and is what I put on the Cimarrons. Great toilet! Hard to get used to the quick, low-water flush, as it sounds like it's not quite finishing, but it works every time. I did manage to clog it up with a bunch of toilet paper, but the plunger easily took care of that. You can either use a standard flush by just pushing the lever, or you can use a lot more water by holding down the lever. This toilet flushes very quickly, also. You almost don't realize it's happened! Great toilet! Highly recommended! I like it better than the Cimarron series.

Rated 5 out of 5 by from Amazing Toilets We bought 3 of these in almond color, and, with 4 adults in the house, we haven't had ANY problems in the 2 months we've had them. Installation was simple, they work perfectly and efficiently, and the water savings is amazing. Tank refill is very quick -- usually done before you finish washing your hands. A very nice upgrade to our home!

Rated 5 out of 5 by from Great Toilet!!!!!! I recently purchased 4 of these toilets for my new home. They are fantastic! The flush is amazing...When I go to the bathroom, everything goes down in one giant flush, No skid marks or anything! Highly Recommended....
