PRODUCT DESCRIPTION
The Aquia IV Two-Piece Elongated Dual Flush 1.28 and 0.9 GPF Toilet and WASHLET S5 Bidet Seat is designed to conceal the WASHLET power cord and water supply hose for a seamless installation.
Part of the newly redesigned S series, the WASHLET S5 features a built in night light, 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 S5 model utilizes TOTO's EWATER+® system when the wand self-cleans. EWATER+ transforms the water into a safe and powerful compound, creating peace of mind by cleaning the inside and outside of the wand 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 Aquia IV features TOTO’s DYNAMAX TORNADO FLUSH®, utilizing a 360 degree cleaning power to reach every part of the bowl. This version of the TOTO Aquia IV includes CEFIONTECT, a layer of ceramic glaze that minimizes waste from sticking to ceramic surfaces. This feature, coupled with the WASHLET PREMIST® and DYNAMAX TORNADO FLUSH®, assists to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning.
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.
The TOTO Aquia IV is designed in TOTO’s Universal Height, which allows for a more comfortable seat position across a wide range of users. Skirted design toilets minimize the need to reach behind the bowl to clean in between the nooks and crannies of the exterior trapway.
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. Additional items needed for installation must be purchased separately: wax ring, toilet mounting bolts, and toilet water supply lines. Compatible with T40 WASHLET+ electronic bidet seat and toilet bowl components only.

Let customers speak for us
from 136 reviewsMy 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
TOTO UltraMax II One-Piece 1.28 GPF Universal Height Toilet and S2 Bidet Seat MW6043346CEFG#01
Nice service, relatively easy to install (I was replacing a much older washlet so plumbing was already in place) and it works great.
Product hasn’t been installed yet as the work on my bathroom renovation continues but I am positively impressed with the service I have received from the company.
I ordered my bidet from overflow. The product had been discontinued, but after having a conversation with Neal, we were able to get a replacement ordered and delivered as originally scheduled. I think they went above and beyond normal service.
It's quiet and easy to use.
Delivery time for my Toto G5A was as promised, no delays. Deliverymen left the G5a in my driveway and did not advise me in advance when the delivery will be made.
It took a while for my contractors to be ready to install the G5A. I would caution DIYers, that this is not a simple installation and unless you really know what you are doing, leave it to the professionals.
I am now using the G5A and appreciate its compactness and relative ease of use. The machine is loaded with options so it is a good idea to read the manual prior to use.
I consider this to be a good purchase.
Thanks
It was wonderful that I was able to talk to the owner of the business. I had several questions.
He made accommodations for delivery and payment. Customer service was stellar.
