Highline Classic 2-piece 1.6 GPF Single Flush Elongated Toilet in White is rated 4.3 out of 5 by 20.
Rated 3 out of 5 by from The powerful flush is the best feature. I purchased 2 of these due to their 17" seat height for ... The powerful flush is the best feature. I purchased 2 of these due to their 17" seat height for my aging parents. The 1st toilet installed by a professional with no adjustments needed. The 2nd toilet would not fill, just run. The installed had to call Kohler and then flushmate and eventually got the adjustments set and worked great. 1st toilet had since December, the second toilet since February. Yes both toilets meet my expectations. I have had 5 of theses toilets at my place of employment and have been maintenance free even with the high iron content in the water. Definitely would recommend this toilet, however due to the issues with the 2nd toilet, best left to the professionals to install

Rated 4 out of 5 by from The toilet I replaced with this one was located in a basement bathroom and kept clogging. This toilet has a much larger opening for waste to flush down and flushes everything effortlessly. I expected it to be noisier but much to my surprise it is not very noisy and refills quicker than I also thought. I am going to redo my upstairs bath and will buy this same model for it. I did not give 5 stars only because of its plain style. I wish they offered this in more styles, but I think it would match with most white tubs and sinks because it is simply styled.

Rated 5 out of 5 by from Seems more advanced than toilets of the past. I bought this model sight unseen online based on the reviews and I am very happy I did. It's a nice size and has quality construction. It does not feel cheap in any way. But when I first looked into the tank I could not believe it has some sort of self-contained mechanisism that controls the flushes and refills. And boy does it flush with a thrust I had never seen from a non-commercial unit before. Note that the flush is a little loud but that's only because it works so well. My only concern about this unit is will I be able to service it ok down the road because it looks so much different than I'm use to. So far this purchase has exceeded my expectations and I find myself telling my company to check out the new toilet!!

Rated 5 out of 5 by from GREAT flusher! We always had a problem with our previous gravity feed toilet requiring multiple flushes or a plunger to handle solid waste. Now every flush is a no-doubter! Works great every time. A little louder than our previous toilet, but I knew pressure assist toilets were like that going in. It was also the highest rated pressure assist toilet in Consumer Reports.

Rated 5 out of 5 by from Love IT! I bought this toilet with very little knowlege and consumer reports. I've never been so happy with toilet as I have this one. Replaced it with a toilet that clogged all the time and had to use a plunger. I've had this toilet for a year and haven't had to use the plunger once. Love the toilet. I am getting ready to replace another toilet and I am going to replace it with this one.

Rated 5 out of 5 by from The toilet works very well. We have these at work and were impressed enough to buy one for home. I only wish that Home Depot offered this model and color (white) with the flush lever on the left. If you are under 5'6" the comfort height will probably be too tall. My husband thinks it is great.

Rated 5 out of 5 by from Powerful Flush This toilet is comfortable with the 17 inch height and it flushes with authority leaving the bowl squeaky clean.
