Rated 4.4 out of 5 by 11 reviewers.
Rated 4.0 out of 5.0 by 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! March 10, 2015
Rated 4.0 out of 5.0 by 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. June 25, 2015
Rated 4.0 out of 5.0 by Boom! 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. December 19, 2014
Rated 5.0 out of 5.0 by Super boom toilet 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.

Rated 3.0 out of 5.0 by 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.. August 31, 2011
Rated 5.0 out of 5.0 by Excellent Product High profile for ease of sitting on, especially tall or older people. Superior performance - very fast and powerful! Flush time is nearly instantaneous, so minor noise increase is offset by fast flush time. January 14, 2014
Rated 5.0 out of 5.0 by Best deal for toilet replacement Install was fast. Seat height is comfortable for tall family!!! Flushing is FAST!!! (Startling at times but fast and efficient!!!) August 22, 2014
Rated 5.0 out of 5.0 by getting another one soon It was very easy to install. The height is great. No need to wait to see if everything goes down. November 4, 2014
