PRODUCT DESCRIPTION
The TOTO® EP Wall-Hung Elongated Toilet with Contemporary S7A WASHLET Bidet Seat and DuoFit® In-Wall 1.28 and 0.9 GPF Dual-Flush Tank System delivers style with innovative performance.
The S7A WASHLET features a soft rear spray, rear cleanse, and front cleanse with the option of an oscillating or pulsating stream. The temperature and pressure of the water are adjustable, each with five settings. The controls are located on a slim, wireless remote. PREMIST® wets the surface of the toilet bowl, aiding in the removal of waste and resulting in a better clean. The wand is self-cleaning, using TOTO's EWATER+ system before and after every use. The WASHLET features a heated SoftClose seat with five temperature settings. The WASHLET features an air deodorizer and a warm air dryer with five temperature settings.
The DuoFit® tank provides a WaterSense® certified dual-flush option with TOTO’s DYNAMAX TORNADO FLUSH. A hole-free rim design that generates a centrifugal, cyclonic rinsing action with the option of 0.9 or 1.28 gallons of water. The skirted design of the EP bowl conceals the trapway, which enhances the elegant look of the toilet and adds an additional level of sophistication.
This wall hung toilet bowl also features TOTO's CEFIONTECT glaze that minimizes waste from sticking to the ceramic. This feature, coupled with the TORNADO FLUSH, assists to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning. The DuoFit® harness allows you to select a mounting height of 15 to 19 inches. This provides the opportunity for you to establish a comfortable bowl height for a wide array of individuals. The in-wall unit can support up to 880lbs when installed properly.
The kit arrives ready to be installed within a 2” x 6” stud setting with a 2" x 6" polyethylene waste outlet. If you require installation within a 2” x 4” setting, you can purchase TOTO’s 2” x 4” PVC outlet kit (THU343).

Let customers speak for us
from 133 reviewsHave really enjoyed my bidet ever since it was installed. Especially during the winter months.
Very good service provided by Mr. Niel. Highly recommend their products and services . I would definitely go back for future purchases.
I didn’t know a toilet could change my worldview, but then I met the TOTO S7A Washlet.
This is not merely a bidet. It is a tiny, porcelain-adjacent butler who appears to have been trained at a five-star Japanese spa. The seat warms itself. The lid opens like the arrival of royalty. A gentle pre-mist prepares the porcelain. And then, when the moment arrives, a perfectly aimed stream of warm water performs its exceedingly dignified work.
There are settings. So many settings. At this point, I am less concerned with “going to the bathroom” than I am with curating an experience.
The heated seat alone feels like a small act of civilization. The deodorizer quietly handles the evidence. The dryer offers a dignified conclusion. And the whole production happens with such technological confidence that you begin to wonder why the rest of your house isn’t also operated by a Japanese engineer with impeccable manners.
The S7A has ruined ordinary toilets for me. A conventional toilet now feels like a primitive ceramic bucket—an artifact from an era when humanity apparently believed wiping with dry paper was the pinnacle of sanitation.
Five stars.
Ten if the bathroom had them.
TOTO S7A: because once your throne has heated seating, a spa-quality wash, and an automatic lid, civilization has officially peaked.
A new shoulder on March 4 2026 and the first bidet installed three days prior. The second one two weeks after the surgery. Both work perfectly. Thinking about putting one in our second home in Calistoga. Highly recommend a bidet.
Bought 2 of these and love them! Couldn't be happier and love all the features they offer... especially love the personal settings!
So far so good. Neal was very helpful when we called with questions. Install went smoothly. Does this come with a remote?
Growing up i am used to use water to clean the tushy and moving to US was a challenge as there is now hand shower or wet wipes. Once i got to know this bidet exists, i bought them. I changed every bothroom and now my kids don’t want to use toilet anywhere else as the seats keeps you warm especially in cold new england winter nights and cleans you thoroughly. 6 years and still working as new!
After travelling to Japan for vacation a couple of years ago and seeing TOTO bidet toilets everywhere, we decided that we needed one of them in the home we were moving to last year. TOTO is a proven high-quality name and we chose to settle for nothing less for a product we'll be using daily for the foreseeable future. We were fortunate to find Everflow, which provided us with the model we wanted at a great price and delivery timing. We couldn't be happier with having chosen Everflow and TOTO.
I’m so pleased with my smart toilet, washes, dries and saves me a lot of toilet paper.
It’s a very worthwhile and reasonable luxury.
Pardon the pun, but I love my Toto. Everything was well packed and shipped, arrived right on time and installed without incident. I did have to route electrical to a convenient spot, but it was totally worth it. An excellent purchase overall.
Tried a couple of brands and this was our overwhelming choice! I like that it has a removable filter to clean and refresh the air.
I love my new washlet toilet! The ordering, shipping and delivery went really smoothly!
Thank you and I would definitely recommend this company!
All my friends want one too
I want to take time to share my experience with Neal, the owner of EverFlow Bidets. I was looking for a Toto toilet that is currently on back order and the remaining piece needed for my bathroom renovation. I had previously purchased the toilet but found out it would not be available to ship until late August. I called around frantically knowing this important detail would create a serious delay to my bathroom renovation. I called all the authorized vendors on the Toto website and had lost hope after all of them told me the same August date. Last call was to EverFlow, I almost hung up and then a friendly voice answered, it was Neal, the owner. I explained the situation and he immediately started to ask questions to figure out options for my dilemma. He asked me to take additional measurements and we concluded what was in stock wouldn’t work. He made one final recommendation, he could reach out to his counterpart to see if they had the toilet in their shared warehouse. I was floored and wondered why he would try so hard to help me. He told me he’d call me back and he did, several times as he shared his strategy for making this happen with minimal additional cost for me. In the end, he charged me the stated price for the toilet, free shipping and only asked for my future business. I told Neal I had to provide a stellar review for his business, not because I found the elusive toilet, but because the experience was so honest and genuine I almost didn’t believe it was true. Neal, as the owner made time to see my request through. He didn’t have to, but he did and went above and beyond to satisfy me as a customer. We only spoke on the phone but his energy was kind and pure. Please support this business. We accept so much from large corporations to the point we have collectively forgotten what it feels like to be valued as a customer. Neal reminded me how that feels, so glad I found EverFlow Bidets!
We are so happy with our purchase of the Bio Bidet Bliss BB 2000. The owner of the company personally helped us with our order. The price of the product is great, the shipping fast, and just dealing with this business was phenomenal!! I have two bathrooms with the Bliss bidet… I have one more bathroom that needs one installed… I’ll definitely purchase from this company when ready. Thanks Everflow Bidets!
