Toto Aquia IV Review- In brief


Check the price

Toto is a Japanese toilet manufacturer with a history of over 100 years of innovation. It is also the largest brand in the industry and the undisputed leader in the production of Washlets. But what about the quality of traditional toilets like the Aquia IV?

My Toto Aquia review provides an in-depth examination of the features. Here is my comprehensive Toto Aquia IV review, which includes details of every feature of the model, both favorable and unfavorable.


The Toto Aquia two-piece toilet comes along with a modern bowl that looks quite great all thanks to its downskirt configuration. The mounting holes and bolts are concealed beneath the skirt, making it not only more visually pleasing but also easier to clean.

The tank is neutral and complements the bowl wonderfully. It’s pretty little, but the forceful flush makes up for any lack of volume.


Aquia IV toilet is coated in CEFIONTECT glaze, which is smoother than standard ceramic glaze and allows the flush to remove waste more easily.

The manufacturer also states that the material provides an ion barrier, which is hard to ascertain, but the cleaner surface cannot be denied. You should expect to clean this bowl 35% less frequently.

Shape and dimensions

Aquia IV has an elongated bowl and comes in two pieces, making it very easy to ship. The normal rough-in is 12 inches, but Toto’s universal rough-in adaptor allows you to quickly convert it to 10 or 14 inches.

Moreover, there are two seat-height options: standard 15-½” and universal 16-⅛”. The universal model meets ADA comfort-height guidelines with a seat on it.

Meanwhile, the overall measurements of the item are 27.6 x 15.6 x 29.6 inches, and the weight is 119 pounds, which isn’t too hefty and allows you to install the bowl without assistance.

Flushing mechanism

The Toto Aquia IV dual-flush toilet uses the Toto Dynamax Tornado flush mechanism, which directs water through the rim. Multiple tests and positive reviews from the consumers show that its flush effortlessly removes waste.

The flush is sufficiently quiet because of the flow and turbulence-resistant tank. Meanwhile, depending on whatever button you push, the flushing capacity is 1.28/0.8 GPF. This is less than what traditional toilets use and allows you to save up to 10 gallons every day.

That equates to approximately 3,700 gallons saved each year and hundreds of dollars saved. Actually, the water saved will compensate for the purchase and installation of the toilet in less than a year.

Some added features

The Toto Aquia IV toilet features water-saving dual-flush technology that produces more output water stream pressure than most other toilets. As a result, the bowl stays cleaner for much longer.

It also comes with a SoftClose seat, which increases height and closes quietly. Other features are available in a more advanced version of the item, which includes a heated electronic bidet seat. For more information, continue reading.

Price and warranty

In general, the regular versions of the toilet, including the universal model, cost between $620 and $760. To get the best deal, I recommend looking for sellers in your area. Additionally, distant shipping costs can easily boost the price to $1200.

If you want to use Toto’s famed washlet, get Aquia IV with this add-on and save some money. The set costs between $1200 and $1500, depending on the flush rate.

Furthermore, the model’s and its bidet-seat variant’s warranty services are offered for one year following purchase. Toilets usually never break down in the first year, therefore I believe they could last at least three years. Longer warranties are only available for the most expensive premium models.


The installation of the Aquia IV toilet utilizes normal hardware and a wax ring but requires a bit more ability to accomplish the necessary stages. Because of the downskirt design that employs hidden mounting holes, placing the bowl and tightening the bolts will be more challenging. To avoid damage, place the toilet softly and slowly.

Now, let us talk about the other variation of the toilet in my Toto Aquia review.

Toto Aquia IV Toilet FAQ

Quick and helpful answers to frequently asked questions-

Yes, this toilet has a great SoftClose seat. It is not necessary to hold it to avoid noise because the hinge allows for smooth and silent movement. This toilet is also compatible with a variety of additional Toto seats, including bidet and smart seats.

-What does the ADA compliant height mean?
It signifies that the toilet is at least two inches higher than a conventional toilet. Making it considerably easier to sit and stand, which is especially important for persons with mobility issues and the elderly.

-Is the Toto Aquia Toilet Compliant with the ADA?
According to the ADA Accessibility Standards Handbook, toilet height for people over the age of 12 should be 17″-19″ from the floor to the bowl rim.

When opened, the conventional SoftClose seat is 3/4″ high, indicating that the construction is barely at the lowest ADA-compliant height.

Toto Aquia comes in two heights: universal and standard. The universal height is 16-1/8″ from the floor to the rim, although the normal height is around 15 inches.
