Rated 5.0 out of 5.0 by Namenotprovided Great toilet for older households
Quality is great, height helps with older adults and flush system is strong and maintenance free.

Rated 4.0 out of 5.0 by WestB87 Great system, but nearly too tall a seat height.
I love the flush of this toilet. It's easy to keep clean and allows you to throw away the plunger. However, as the man of the house, I am 5' 8" and the seat height is nearly too tall for me. My thighs are at an angle slightly greater than 90° to my hip joint when sitting on this. Therefore I find myself with the seat edge putting pressure on my hamstrings which I alleviate if need be by lifting my feet to tip-toe. My wife, whom is 5" 7", can use the toilet, but not comfortably as she MUST sit with her feet tip-toed. I've still two very old toilets to replace in this 30 year old home, so I believe I will go with the Wellworth model as it has a seat height more accommodating to folks like my wife and I. I'm glad I didn't order all 3 at once because the height of this toilet would be completely ineffective for my potty training children. That said, I still love the flush power and the cleanliness. Kohler really does make a fantastic product.

Rated 4.0 out of 5.0 by corlinc Kind of loud, but no more sweaty tank!
The flush is fairly loud but it gets the job done and the tank doesn't sweat since the water is in the pressure assist tank instead of the china tank. Like I said, a little loud but I can live with that and not have to worry about rotting floors and mold!

Rated 4.0 out of 5.0 by Drew verdict not in yet
By deign this may be the answer to my situation with respect to slow water flow due to no basement and short drop from toilet to elbow where it connects to sewer line. I have suspected this caused the frequent plug ups requiring plunging. That said, I have not installed it yet so I really can't do an evaluation on this item. A consideration for anyone installing this kind of toilet would be to check your drain lines for 90 degree turns in the toilet drain line or any other possible restriction in the line especially close to the toilet, as Kohler claims it can flush a bag of golf balls i.e. very high flush pressure in the line. I may have to change a 90 degree elbow to a 45 degree elbow in the line but I haven't checked this out with Kohler. I hope my concerns are not justified.

I've installed 7 toilets with the Sloan FlushMate 504 system so far, and they all work extremely well - we have never had a clog in any of them, whereas the toilets that were in those locations before had become clogged repeatedly. The sound level is a bit higher from the pressure-assisted flushing, but it's very fast. I think the location of the handle on the Kohler K-3493 was a bit better. The K-3519 works just as well overall, but I had to stick a piece of styrofoam in front the inner tank so it wouldn't tip forward and disconnect the lever - I don't think the switch from front-mounted to side-mounted was designed very thoughtfully.

The toilet works - the pressure assist that allows it to function for 1gpf causes a louder, surprising at first, sound. The noise doesn't last very long, but will wake a nearby sleeping person. The flush handle returns with some force, which can also be surprising at first.
Mine was delivered with a defective actuator rod, so the toilet would not flush with the handle - the actuator arm (A custom bent stainless steel rod) would not reach/engage the flush handle arm. It took Kohler a week to provide a satisfactory replacement that should have been over-nighted on a $350+ item.
Recommended for its water saving function - I'm less than impressed with Kohler Customer Service.

Rated 4.0 out of 5.0 by Ozzie Great purchase
The product was easy to install and set up. Everything that was needed was provided. The only downside was the packaging. The spray foam packing material was not installed correctly and was sprayed all over the handle and tank requiring a lot of time and effort to remove. No instructions were provided for a solvent to remove the spray foam.

Rated 3.0 out of 5.0 by BillB Noisy Flush, otherwise great
This product is not ready for residential use with the noise of the pressure-assisted flush, especially in a small space like a powder room or water closet (WC). When we saw this advertised as a 1.0 gpf residential product, it was assumed Kohler had developed a means of muting the sound volume of a pressure-assisted flush. Not so. It still sounds like your are using the restroom in an office building, arena, or rest area. The product is otherwise great. Efficient and the coating inside the bowl makes cleaning minimal. The force of the pressure-assisted flush appears to insure the toilet will never be stopped-up. But it's the noise ... can't use the MBR bath at night because the flush wakes up the sleeping spouse! Not ready for residential prime-time..
