PRODUCT DESCRIPTION
NOTE: This item may only be purchased in combination with a Bidet Toilet Seat from this store. Please feel free to contact us with any questions.
The Aquia IV One-Piece Elongated Dual Flush 1.28 and 0.9 GPF Universal Height WASHLET®+ Ready Toilet is the epitome of modern form and function. The skirted design conceals the trapway, which enhances the elegant look of the toilet and adds an additional level of sophistication.
The one-piece design is not only aesthetically pleasing, but also offers the benefit of being easier to clean versus a two-piece toilet. By removing the gap between the tank and bowl, we eliminate the hiding place for dirt and debris. An additional benefit of the one-piece toilet is that there is no threat of leaks from bolts or gaskets that can occur in two-piece toilets.
The Aquia IV features TOTO’s DYNAMAX™ TORNADO FLUSH®, utilizing a 360 degree cleaning power to reach every part of the bowl. The DYNAMAX TORNADO FLUSH helps to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning and the enhanced design of the Aquia IV inner bowl reduces water flow resistance and turbulence; resulting in a quieter flush.
The chrome center-mounted push button that sits atop the tank allows you to proactively conserve water by choosing between a 0.9 GPF rinse or 1.28 GPF for tougher jobs. This version of the Aquia IV offers TOTO T40 WASHLET+ compatibility for when you are ready to upgrade. WASHLET®+ toilets feature a channel on the bowl surface to help conceal your WASHLET+ supply line and power cord for seamless integration.
The newly redesigned lid style resides flush with the toilet bowl, providing a streamline look and giving the impression of an integrated system. The minimalistic display provides a more subdued appearance to your WASHLET. Skirted Design toilets also minimize the need to reach behind the bowl to clean the nooks and crannies of the exterior trapway.
The Universal Height design allows for a more comfortable seat position across a wide range of users. The TOTO Aquia IV meets the standards for EPA WaterSense®, and California’s CEC and CALGreen requirements. The Aquia IV comes ready for install into a 12" rough-in, but may be adapted for a 10" or 14" rough-in with the purchase of a separately sold adapter.
Includes a SoftClose® toilet seat (#SS124). Additional items needed for installation and use must be purchased separately: wax ring, toilet mounting bolts, and water supply lines.

Let customers speak for us
Have 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!
