Answer: 
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.

Answer: 
I would not because if it gets clogged you'll find it impossible to unclog. The water line should be as high as you can get it to stay without clogging it to do so. To test the waterline pour a small bucket of water into the bowl and let it sit for a minute, that will give you accurate results

Answer: 
correction - Mike I believe the size at the the tank ( ballcock) is 7/8 not 3/4. I just Looked at mine. That will not be a issue for you because it's a standard size. The water supply line and the nipple on the shutoff valve will determine what you need . That will be either 3/8 or 1/2 inch. 3/8 works fine. Tank fills pretty fast

Answer: 
I would not recommend installing this toilet in a restaurant because of the high maintenance. It flushes great so you won't need a plunger but you will need a bowl brush because the inside of the bowl soils just about every time some one does a number 2.
I see a lot of really high rating for this unit and I am really surprised as it is just not that good. My concerns of note:

I would not recommend installing this toilet in a restaurant because of the high maintenance. It flushes great so you won't need a plunger but you will need a bowl brush because the inside of the bowl soils just about every time some one does a number 2.
I see a lot of really high rating for this unit and I am really surprised as it is just not that good. My concerns of note:
The handle has to be held down for several seconds to get a complete flush.
A 1.28 GPF does provide enough water surface in the bowl to prevent the it from being soiled. And per the manufacturer there is no way to increase water surface. It is what it is.
The need to frequently use a bowl brush to clean the inside of the bowl and the 2nd flush to clear the water. Not much if any water is really saved? Oh yeah the bowl brush has to rinsed too.
The water supply lines are just standard lines which are sold at Home Depot for a very reasonable price. The inlet to the tank is 3/4. My unit came with a plastic nut so supply tubes can be used as well Read Less

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!!!

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.

Rated 4.4 out of 5 by 129 reviewers.
Rated 5.0 out of 5.0 by Very quiet toilet - great product and easy to install Easy assembly and the flush valve is great. The toilet is very quiet when filling. August 17, 2016
Rated 5.0 out of 5.0 by I replaced all my toilets with this model...a great Kohler toilet! Very easy to install. The tank parts came completely installed with flush valve, handle, and all other tank parts. Plus, the toilet flushes quickly and completely using only 1.28gal. of water every time. Both of my toilets are the same model from Kohler. I highly recommend you consider this fine product! August 16, 2016
Rated 5.0 out of 5.0 by Very Nice Toilet Replaced an American Standard toilet with this unit. Only problem was after installation there seemed to be very little water in the bowl. The little black hose that feeds water to the bowl was too long, and drimped which prevented water flow to the bowl after flushing. Pulled the hose and cut it to size, and the bowl filled with water normally. Overall, and excellent toilet. August 7, 2016
Rated 2.0 out of 5.0 by Doesn't flush properly Installed this at my son's house. When you flush, you have to hold the handle down or it quits the flush process prematurely. I've tried adjusting every which way and no luck. Wish he had purchased a different toilet. May 5, 2016
Rated 5.0 out of 5.0 by Work great! I read a lot of reviews before deciding on this toilet. We installed it with a Danco Perfect Seal toilet ring (DO THIS), and it went in easily. The seal was great, because we were able to remove the toilet to put in longer floor bolts and seat it again. It flushes great, and is not noisy. At first the water line was too high, but we were able to easily adjust it to the marked level. I like the comfort height. We added a Kohler self closing seat, which is sturdy and works well. Do check for damage--the toilet was upside down in the shipping boxes, and the bowl broke through its box, but was undamaged in the shipping box. The lid had a broken piece on the inside, due to it being shipped just sitting on the tank with no padding or strapping. It didn't affect the fit of the lid, so we didn't return it. December 17, 2014
Rated 5.0 out of 5.0 by Great toilet that works every time. Great toilet that works every time the first time without having to flush twice. March 8, 2016
Rated 1.0 out of 5.0 by 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. March 4, 2016
Rated 1.0 out of 5.0 by 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. February 12, 2016
