PRODUCT DESCRIPTION
TOTO Aquia IV One-Piece Toilet with WASHLET S5 Bidet Seat
The TOTO T40 WASHLET+ Aquia IV combines a sleek, one-piece design with advanced bidet technology for a clean, modern, and comfortable bathroom experience. The WASHLET+ system conceals the power cord and water supply hose, creating a seamless, clutter-free look that complements any bathroom style.
Smart Comfort Meets Modern Design
Paired with the newly redesigned WASHLET S5 bidet seat, this model offers a luxurious upgrade to your daily routine. Enjoy adjustable front, rear, and soft rear washes with oscillating and pulsating spray modes—all controlled from a slim, wireless remote. Each function features five temperature and pressure levels for personalized comfort.
The S5’s heated SoftClose® seat keeps you warm year-round, while the built-in nightlight softly illuminates the bowl for easy use in low light. A warm air dryer and deodorizer complete the experience, reducing toilet paper use and maintaining freshness.
Advanced Hygiene with EWATER+® and PREMIST®
The PREMIST® function sprays the bowl before each use to help waste rinse away easily. After each wash, EWATER+® automatically cleans the wand inside and out—no chemicals required. This self-cleaning system keeps your toilet fresh, hygienic, and low-maintenance day after day.
Powerful and Efficient Flushing
The Aquia IV toilet features TOTO’s DYNAMAX TORNADO FLUSH®, delivering 360° cleaning power that reaches every part of the bowl. The CEFIONTECT glaze prevents waste from sticking, reducing the need for scrubbing and harsh cleaners. Choose between a 1.28 GPF full flush or a 0.9 GPF light flush using the chrome dual push button for efficient water conservation.
Designed for Every Home
Built at TOTO’s Universal Height for optimal comfort, the Aquia IV’s skirted one-piece design eliminates gaps between the tank and bowl—making cleaning simple and fast. It installs easily with a 12" rough-in and can be adapted for 10" or 14" rough-ins with optional parts (sold separately).

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!
Impeccable customer service and prompt delivery. Thank you Neil.
Neil is so awesome and honest! Thank me later!!!
My wife and I rented a large cabin up north and they had the Toto washlets installed on their toilets. I was using the toilet and noticed a remote mounted on the wall. Well of course I started hitting buttons and realized I just entered a spa day for my bum!!!! I was quick to let the rest of the family know….Everyone was using it by the end of the weekend and now I’m looking to install a few at our home!
I've been using washlets in my home for 20 years. Recently, we decided to replace the oldest one and install one in an upstairs bathroom. I bought 2 BioBidet washlets on sale. Today was our day to overhaul the bathrooms and everyone was really happy. One bathroom got a new toilet and the washlet from the powder room. My bathroom and the powder room got BioBidet washlets. Everything looks so good and functions perfectly. Installation is easy. There are videos if the manual isn't for you. Once you use a washlet, you will not be going back.
I am absolutely delighted with my new Toto Washout Toilet Seat. It provides an experience that you just have to see for yourself. It wi change how you think about using the toilet! I had an issue with my shipment and Overflow Bidet made the mistake right - in a hurry! I wouldn't hesitate to recommend these guys in any of my future purchases. Thanks!
We have not installed the bidet seat since our apartment is currently under construction but I must say how ordering was smooth and customer service answered all my questions. I look forward to using this bidet seat!
Great product. We have purchased 3 of them. Also great service from Everflow. Love to talk to real person.
Less than a week into our new Washlet S5 and we are pleased so far. We were very happy with the customer service from EverFlow Bidets. The seat was backordered and the owner called to discuss our options with us because of the backorder. I called the 1-800 number to check on the back order status and again spoke with the owner. It was shipped when expected based on the Toto update and arrived quickly once it was sent.
We received a broken bowl from Fed Ex and called to inform the company of this. No issues at all was replace immediately! Now I am loving my toilet with Bidet seat!!
I’m very pleased

Nice service, relatively easy to install (I was replacing a much older washlet so plumbing was already in place) and it works great.
