Key Features & Innovations


TOTO’s extraordinarily smooth CeFiONtect glaze prevents particulates from adhering to porous, ceramic surfaces. The ion-barrier in CeFiONtect keeps everything cleaner, longer. Less cleaning means fewer chemicals in the environment and less water used for cleaning.

The surface layer that makes up the ionized barrier is more consistent and uniform and has a higher density on the CeFiONtect surface than on the conventional surface.

Creating more smoothness helps minimize debris from sticking. With nothing to cling to particles can be washed away with every flash.


3-D Tornado Flush

The 3-D Tornado flushing system not only features three powerful nozzles that create a centrifugal, cyclonic rinsing action but also the option of choosing between 0.9 or 1.28 gallons per flush. This technologically-advanced high-efficiency system is remarkably effective, saving you up to 35% more water than the standard 1.6 GPF. The modern hole-free rim design also means that it performs more consistently and is easy to clean.


The skirted design, available in many modern TOTO toilet collections, offers clean lines, minimal flourishes and geometric precision. This style is elegant and smooth, concealing the trapway, and features a base that is easy to clean and maintain.

Universal Height offers sinks and toilets at a more manageable height, making the bathroom more accessible and enjoyable for everyone. This simple design principle allows all people, from the beginning of their days through the rest of their lives, to completely enjoy their bathroom experience, regardless of age or ability.

Pros: I'm glad I got it. Now my husband uses it too. He didn't use the simple bidet we had, but this one he is. It's very expensive, but well, we never know what's gonna happen in our lives, at least i got to try and use this very fancy toilet and washlet with everything that goes with it. Decor planet t
Cons: Very pricey , for the price, it's not illuminated. When flushing, even with full flush, the dirt in most back side top rim doesn't get cleaned, so need to ff up up with manual cleaning. Husband has to do some wall breaking to put the electrical outlet and do some plumbing. He did good. But I'm happy
Bottom Line: I would recommend this product to a friend

Pros: Very comfortable. Keeps both the commode and the person using it clean. Sleek looking.
Cons: Difficult installation. LCD screen on remote is not backlit.
Very difficult install. We had to hire a plumber that specializes in “exotic” toilets. First they had to move the water supply line 6” to the left. That was $125. Then a drywaller had to patch the hole $40. Then the plumber thought he’d have to cut a section of the baseboard out behind the toilet. Thankfully he did not have to do this. But to install, it must be anchored to the foundation. which requires special tools. And you must tell them if your foundation is post-tension. The bill for this two-step process was $400. The house was built in 2002. Given the final product is excellent, be forewarned that installation is complicated and expensive.
Bottom Line: I would recommend this product to a friend

Pros: Slick looking, easy to clean, pre-mist and deodorizer features, top-notch bidet features, WARM water, form factor of seat - very comfortable, heated seat, auto-open and close seat
Cons: Will require a plumber (unless you are a major plumbing DIYer), dryer is not going to dry you in a second or anything. That's really it because it is amazing.
This is a game changer if you will use the bathroom it is in a good amount. It is definitely a "luxury" purchase, but this Toto delivers for the money. First, for a toilet, it looks really slick compared to a normal one. Sleak, clean, and future looking. The auto seat is great. You can change the sensitivity, so it does not go up when you are far away. Only will probably scare the heck out of a neighbor or someone going in there the first time....WARN them. The bidet features are all top-notch. Heated seat is great, the pressure of the water is strong, the warm water is amazing (I am not sure how anyone could use the cold water ones), pre-mist and deodorizer are really great (the pre-mist may scare someone the first time as they may think it is flushing or they are doing something wrong). The form factor and comfort of the seat is great as well. It is a little different but much more what you want. Instead of straight-line flat, it has curve more indicative of your back. Just be sure you lean back before using the bidet feature to know ideal location of stream. Delivery was great and seamless. Price was best I had found anywhere on-line. And Customer Service was very helpful. Only negatives are that the remote could be a little more impressive like the toilet. It works perfectly fine, but with such a sleek toilet, it is odd the remote does not look more stream-lined. Also, as people have mentioned, the dryer will not make you dry in a second, but it is not that bad. Big recommendation. Total game changer. Once you go bidet, it is tough going to a regular toilet again.
Bottom Line: I would recommend this product to a friend
