Customer Questions & Answers

Would you recommend putting this type of toilet in a restaurant? What size water line is needed for this toilet half inch or three quarters?

Asked by: Mike
Terrible flushing toilet so unless you have a standby cleaning crew the toilet will always be dirty and customers will hate it. Very poorly designed bowl and flushing system.

Asked by: Anonymous

Explain high efficiency.

Asked by: Ronald
I have had my Kohler 2 piece with the high efficiency aqua piston technology..It was installed by a professional plumber approx 9 mos ago..Lately I have heard a slight noise from the inlet to the tank..On further examination, it appears that the lift is not shutting off the flow into the tank completely.. I think the float is not adjusted and will not stop the water from running. I have had to shut off the water inlet line , beacuse I am afraid I am using /wasting a small continuos run..It is ever so slight, but I can see it running, without completely shutting down after all flushes/refill process..The water level is up to the bottom of the inside plastic nut connecting the flush arm..What are my options..The technology was in the tank when it was installed..I trusted that it would last!!!

Is this a good height for a 5'3" person w/arthritis?

Asked by: Anonymous
Hello, I am a female just above 5'4" and I've found that I like these toilets because when you sit down, they actually feel taller than most toilets - the elongated style seems to be comfortable for me and supportive. I wouldn't suggest a wooden toilet seat if you have trouble lifting things... also note that ours did not come with the toilet seat. We had some trouble ordering two of these through home depot online - they come each in two packages and one of the 4 came broken - it was hard to replace. Best Wishes!

Customer Reviews

Cimarron 2-piece 1.28 GPF High Efficiency Elongated Toilet with AquaPiston Flushing Technology in White is rated 4.3 out of 5 by 188.
Rated 1 out of 5 by from Kohler toilet nightmare I purchased two Kohler cimmaron comfort height toilets. Nine months after the purchase and installation I got a phone call from the city telling me my water meter was spinning out of control and I had used 55,000 gallons of water in less than 30 days!!! I normally use under 2000 gallons. The problem was that wretched aquapiston. There was no sound of running water and no movement in the bowl or the tank, unlike a traditional flapper type toilet and as everything is invisble inside the piston I had no way of knowing it was continously forcing water through . My water bill came to over $700.00!!!!! I am senior and living on a fixed income and this is devastating. Kohler have refused to compensate me for the excess water bill which was due entirely to the faulty product, depite documentation, substantiating the source of the loss over my regular water bill which averages $20 per month. AVOID Kohler. Avoid this happening to you. Bad design, defective product, total lack of concern for their customers. I'd give a negative star rating if it was possible. I've since heard from plumbers that Kohler have a lot of problems and have replaced with American Standard.

I like the added two inch height. I think for seniors it is a great feature. We had a standard toilet that continually leaked water even after replacing all the gear in the tank. The high-efficiency water savings should be great. Despite the (online) advertised $100 rebate available from the city on your water bill; that depends entirely on YOUR city. Ours did not provide that rebate. (I think that advertising should be omitted in the future.) The biggest problem with this toilet was the shipping to our local Home Depot. Twice the toilet arrived broken, once it was the tank, the second time it was the base. The toilet I got was the undamaged part of the first two shipments. I fault the vendor. They didn't pack it sufficiently before shipping it to HD.

I failed to notice the fine print that this $279 toilet did not come with a seat. In this economy, I find this absolutely outrageous for the price I paid for this item. Although the picture from my purchase showed a seat, I do not have the money at this time to purchase a seat to go with it. I appreciate that the toilet saves water as it's basically a one-flush guarantee, but for what I paid, I feel that I was taken advantage of.

Rated 5 out of 5 by from Great buy I bought two of these to replace my shorter round toilets.elongated ones are nice.taller is definitely a plus. These were a breeze to replace.I had a tougher time on one because the flange was rotten.Added an adapter plate. All good. No tank bolts are a huge plus also. Have to buy one more now. Recommend this.

Rated 1 out of 5 by from Terrible performance Looks great, decent price... but it doesn't flush properly. Never gets any of the solid matter stuck to walls so it needs 2-3 flushes + brush every single time...(Water savings = ZERO) It also "burps" sometimes during a flush, throwing a cupful of water out on the floor... Yuck! I have two of them and I HATE them both. Kohler products have a reputation for quality but this one is really poorly designed.

The AquaPiston is a con, its not a powerful flush, in fact I had to buy a toilet brush to get the "you know what" off the sides. For $500 I'm stuck with it.

Rated 5 out of 5 by from I love it This toilet is exactly what I wanted. The extra height is very helpful, love the color (almond), elongated makes it very comfortable and it flushes perfectly.

Rated 5 out of 5 by from It works swell Was nervous about making the switch to a low flow toilet but with that piston power, there are no worries. Delivery was great and quick via ups.
