Rated 4.4 out of 5 by 25 reviewers.
Rated 5.0 out of 5.0 by Great Toilet The power assist of this toilet makes it well worth the money. This is my second power assist toilet that I installed and it is in a rental unit. I wish it was going into our flat instead because the opening in the bowl appears larger than the one we have which we purchased many years ago. The larger opening would certainly be a benefit.

Rated 5.0 out of 5.0 by It's About Time!!! What a BLAST, literally and figuratively. The best toilet I ever flushed. My wife wanted to install a commercial, (tankless) toilet out of frustration. We did our research and it sure paid off. As my uncle who was a plumber always said, "it needs to flush with authority." Well this baby RULES. Commercial toilets are wimps compared to it. Another positive is that there isn't any moisture build up on the tank because of the inner air pressure tank. A little louder than your normal, Wait and Pray toilet, but it all happens so quick it doesn't really matter. It's also fun watching peoples reactions when they come out of the bathroom. All this and only 1.4 gallons. Would never buy anything else unless they improved this one. Kohler wins the race way ahead of the pack with this one. September 17, 2009
Rated 1.0 out of 5.0 by Buyer beware We bought the wellworth with pressure assist flushmate and initially thought it was the best toilet ever. 4 years later, I notice the toilets are NOT flushing out fully....just with urine. Then we noticed that the pressure is starting to get loud. No, it is not the 503 recalled model. I just noticed a strong mildew smell in my beautiful bathroom and when I pulled the lid off the back tank it just reeked of mildew. We do not see any mildew, cuz it is a sealed valve but the smell is a giveaway. I am 60 years old and have NEVER had to replace a 4 year old toilet. They sure don't make things like they used to.

Rated 5.0 out of 5.0 by Wellworth Kohler toilet This toilet is a BEAST! I would suggest you don't flush while sitting on it for fear of it sucking you in! LOVE this toilet! We have someone in the house who is known for stopping up toilets. Hasn't happened yet with this mean thing! Would definitely recommend it. May 26, 2009
Rated 5.0 out of 5.0 by Buy one! 4 years ago I replaced older toilets that clogged constantly with the best conventional toilets I could find. The new toilets worked a lot better but still had a few clogs a month. I was tired of dealing with clogs and maintenance issues with toilets that were only 1 year old. So, 3 years ago, I purchased two of these Kohler Wellworth toilets and have never had a clog or any issue what so ever! They get used constantly in our busy office with 11 employees and they just work, every time, no question, it is going to go down. They also clean themselves extremely well. I paired them with high quality soft close seats which have also held up great even with cleaning multiple times a day. After experiencing the performance of this toilet in a commercial environment, I get a little angry when I go to a restaurant and the traditional toilet is clogged. Yes, they are loud, but that is a small price to pay for guaranteed to go down performance. I am writing this review because I need 3 more of these toilets for my new home. March 12, 2014
Rated 5.0 out of 5.0 by Great Toilet If you're looking to forget those troublesome "plumbers' helpers" accesories (namely the plunger) you can throw all of them away. This toilet is great. I believe they should make air assist flush toilets mandatory. I had a couple of toilets here that just wouldn't get the job done, if you know what I mean. I bought these to replace and there's no question as to whether or not everything goes "bye bye" when you hit the flusher. Bye Bye problems. I'll never own another toilet. September 12, 2012
Rated 5.0 out of 5.0 by Awesome Toilet - You Must Buy This One Best toilet ever. Very powerful. As advertised. Easy to install. Beats all the other toilets at the store and well worth the expense. I promise you will be satisfied with this. I purchased it from Home Depot's website and received it in 3 days by UPS Ground in two boxes. Nothing was damaged and it only took me 15 minutes to install. Make sure you buy a toilet seat since it is not included. The pressure component is already installed in the tank so you don't have to do nothing except put the wax seal on the bowl, fasten bowl to the floor drain, and attach tank to bowl. A+ item in my book. Going to buy two more for my other bathrooms. Good Luck! April 30, 2011
Rated 5.0 out of 5.0 by Powerful flush! I've always been in love with the power of a commercial toilet, that emphatic *KAWOOSH*, and this is as close as I can get without some serious plumbing work. The pressure tank is reliable, powerful, quiet, and refills very quickly. Watch some of the videos on the Kohler site if you're on the fence: the shape of the bowl really does prevent staining and buildup on the walls of the bowl. Pair it with a quiet-close seat and you've added a lot of class to the bathroom. September 26, 2009
