Rated 4.3 out of 5 by 38 reviewers.
Rated 4.0 out of 5.0 by Very Nice Toilet but the Instructions are Less than Adequate Thankfully, my husband has worked as a plumber's apprentice. This toilet is quite a bit more difficult to install than a standard toilet, particularly if you have to drill into concrete. The instructions leave out important information that we were able to trackdown on line. Even the parts list was sketchy and not very detailed. September 2, 2014
Rated 4.0 out of 5.0 by Great purchase:) Looks beautiful, does not come with a seat. Taller seat than normal. Need to purchase separate from Toto, so it is not convenient. Installation it's OK. December 17, 2014
Rated 5.0 out of 5.0 by Excellent toilet with great value- but a couple of caveats!! This is a terrific toilet. It's fairly easy to install, high-quality, looks good, and a very good value for the price. I love the dual-flush capability and low-flow. Flushing power is terrific, and #2 flush is hardly even needed! But there are a couple of things you need to be aware of if you're considering buying this model. While installation is pretty straightforward for a toilet, it requires a small adapter over the wax ring that gets bolted to the flange. The toilet itself is secured by its weight on this adapter, and two small blocks screwed into the floor, between flange and wall. No big deal for most installations, but might cause a slight issue with some floors. Also, the water supply line connect to the tank THROUGH the rear of the bowl unit. You may need a longer supply line in some cases. But my biggest headache has actually been finding the right SEAT!! There is no access to the seat mounting bolts from below (they are internal), so only seats with external hinges can be used. I've had a lot of trouble finding one that I like that can be mounted on May 19, 2013
Rated 5.0 out of 5.0 by Eccellent Toilet BOWL -- Strontly Recommended After the first one arrived to my home broken and the second one arrived to store broke as well I was thinking about moving to a different style. However, Home Depot convinced me that they will take every extra caution required to get the third one as expected and I decided to go for it. I just installed it last night and I can not be happier. It looks excellent -- much better than when I saw it at the showroom. It works perfect as well. It was little more difficult to install compared to standard design as I had difficulties drilling into tile, but once that was done everything went smooth. I really recommend this product and will put two more as soon as I decide to work on my remaining bathrooms. August 30, 2014
Rated 5.0 out of 5.0 by Toto is the best Had to drill holes into marble floor and sub-terrazzo but plumber did it all OK. Love the toilet. Looks clean and modern. Very nice quality. December 17, 2014
Rated 4.0 out of 5.0 by Great flush, good quality but not an easy install 1st toilet arrived damaged "expedited" 2nd toilet came only 1 day earlier than std delivery (not happy, but HD gave me a small gift card... Paid for seat so ok). My husband installed and it took him 3 days, mostly b/c of getting the right drill bit for the tile. He is a DIY and good so just beware, the install is not like normal non-skirted toilets but it's not impossible either. He has already started on the 2nd install and it will only take 1 day. We have 2 kids, 8 and 10, and I was worried about the cleaning. We've had for a week and no issues whatsoever. #1 flush covers it fine with 1 flush. And I don't need to hold down the button, just a good firm press and you're off. #2 is very powerful. Much better toilet than our original 1950s ones we replaced. This is a little pricey but worth it. And the slow close seat is a no brainer, esp with kids. August 4, 2013
Rated 5.0 out of 5.0 by Best Toilet, low gpf, clean design The toilet was picked up at Home Depot, it was package very well, considering it is china. The clean design is great for cleaning. The dual flush is very efficient, even flushing at the lower rate nothing has ever got stuck or required a second flush. The installation took about twice as long because of the non standard mounting, but it sure made the toilet look good. Suggestion would be to use a thick wax gasket instead of using a flange spacer, it worked much better and no leaks. March 24, 2015
Rated 3.0 out of 5.0 by Leaking toilet my plumber found that the two parts did not merge sufficiently, which resulted in a small leak. Returned this one and installed a different brand that is operating correctly. December 10, 2014
