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
Is a great product, easy install, ran into some shipping issues but folks at Everflow were great to work with, they ultimately got things resolved so that I received the product in a timely manner.
TOTO S2 Electronic Bidet Toilet Seat
If you’re looking for best-in-class customer service, this is your place. EverFlow has earned my business for life.
We ordered a high-end bidet from EverFlow about two weeks ago, and the product showed up within days, not weeks. Unfortunately, the courier damaged it during transit. I was pretty nervous about what dealing with customer service on an issue like this was going to look like.
Much to my surprise, when I called, I ended up speaking directly with the owner of the company. He was incredibly kind, apologetic, and genuinely concerned about making the situation right. There was no runaround and no arguing over whose fault it was. He simply took ownership of the problem and immediately got a replacement unit on the road.
From the original order to receiving the replacement, the entire process took barely over two weeks.
That is one of the most impressive customer service experiences I’ve had in a long time. Problems happen, especially when third-party freight companies are involved. What separates great companies is how they respond when something goes wrong.
EverFlow absolutely nailed it. They’ve earned a customer for life.
Neal, the owner of Everflow Bidets was a huge help picking out the best choice for me. He answered the phone personally on Saturday morning and we had several conversations to arrive at the best choice. Best customer service I have experienced in a very long time.
Replaced all 4 toilets in our home and all are performing identically after more than 6 months in service -- a testament to the product's overall quality control. Control panel is easy to navigate for daily use while "set & forget" functions (seat heat & energy savings settings, night light, etc.) require reference to the owner's manual. Neal was refreshingly informative and even passed some bulk shipment savings on to us for the palletized arrival. Couldn't be happier!
TOTO S5 Electronic Bidet Toilet Seat
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.
