TOTO Aquia Wall Hung Toilet Review
TOTO Aquia Wall Hung Toilet – Elegant, Space Saving And Powerful
If you re looking for a TOTO wall hung toilet, inevitably you will come to learn about the Aquia and Maris.
These are the only 2 wall mounted toilets that TOTO produces for the USA market. Else where, particularly in Asia, they have like over a dozen models of wall hung toilets.
So back home….., between Aquia and Maris, which is better?
Instead of writing 2 separate reviews for the two, let’s focus on the more popular TOTO Aquia CT418FG. But don’t worry, there will be comparison along the way. And you will soon learn why the Aquia model is so popular among all the wall hung toilets out there.
NOTE: It’s a long post so please use the Table of Content and anchor for your easy browsing.
Everything You Wish For In A Toilet
Americans are too used to the floor mounted commode with a tank. That’s fine when living spaces are not an object. But for the city dwellers, space is almost a rare commodity.
It is impractical and expensive to have a bathroom sized for a regular tank and bowl crapper. Ask the New Yorkers.
Will you sacrifice your living space for a bigger bathroom just so you can have a normal toilet?
You probably will if there isn’t a good enough solution. But now, with the wall hung toilets getting into more homes, complaints of small bathroom spaces are beginning to sound more like excuses.
Great Space Saving Toilet, Easy To Clean With SanaGlossWall hung toilets such as the TOTO Aquia CT418FG will fit nicely into a 30″ x 42″ space. That’s about 9 inches saved on the length compare to a regular toilet.
Not only it frees up the floor space underneath, it makes cleaning real easy. Also, there are less area to clean since the tank is hidden. And the SanaGloss Surface needs only water to keep clean, no need for harsh chemicals or detergent.
In fact, the ease of cleaning and maintenance is the number one reason why people loves this TOTO Aquia wall hung toilet.
Plus, the tankless look gives you a sense of spaciousness; a floating toilet bowl if you will.
What Is The Difference Between SanGloss And CeFiONtect?
If this is the first time you heard of SanaGloss, it’s a TOTO proprietary ceramic glaze. A special coating developed by TOTO which enhances the smoothness of ceramic surfaces.
The idea is to prevent stubborn waste from sticking to the otherwise porous ceramic surface of the bowl.
The other name for SanaGloss is CeFiONtect, which TOTO brands it for the Asian market. They are exactly the same ion-barrier surface coat you find in this TOTO Aquia wall hung toilet.
You Decide What Seating Height You Want
Unlike the floor-mount toilet, you now have the freedom to choose the seating height. This is because the bowl support is on the wall, and not bound by the bowl height like the floor mounted model.
According to TOTO’s specification, you have a range of 15″ to 19″ you can use to set the seating height. So if you love the comfort height you have tried on your friend’s toilet during a visit, you can fix it at between 16.5″ to 17.5″. Or bring it down to the lowest 15″ for a regular seating height.
This is good for those with special needs. You can fix the height to the same level as the wheel chair where the person can just shift over easily. That will provide safety and convenience for both helper and the injured or handicap person.
However, a misconception about the ‘adjustable height’ is that, the bowl can be adjusted up or down at will. No. Unfortunately, you can’t. You have to decide on the seating height during installation. Once it’s installed, the height is not adjustable.
Water Saving Dual-Max Flushing System
This TOTO Aquia Wall Hung Toilet features the Dual-Max flushing system for clearing solid and liquid waste. The 1.6 gpf is for clearing solid waste, or a full flush if you like. And the 0.9 gpf light flush is enough to clear liquid waste efficiently.
Unlike the single flush toilet, you can choose to save water with the 0.9 gpf flush when you are not clearing heavy waste. And with an average flush of 1.28gpf, it has earned the WaterSense label.
Exceeding Industry Standard In-Wall Tank SystemThe TOTO Aquia Wall Hung toilet consist of 2 main parts; the in-wall tank system and the bowl.
The in-wall tank system consist of a water tank, the flushing mechanism and the frame. The frame is the main structure that holds the water tank and provides support for the bowl.
The DUOFIT frame is able to support up to 880 lbs load. Exceeding the requirement of The American Society of Mechanical Engineers standard, ASME A112.6.2.
Clog Free Bowl Design
Unlike the conventional toilet bowl, the trapway is a short straight-to-the-drain 2.125″ passage way. You will not get that swirl or water level build up in the bowl on a flush. This is because it’s not a siphonic design.
The bowl of this TOTO Aquia Wall Hung toilet is of a washdown design. It uses the full gravity force of water to push the waste down to the drain outlet.
It can’t create any siphon action like your other conventional toilets.
And typical of washdown toilets, clogging is rare. If ever you experience a clog, it’s almost always at the drain pipe and not at the toilet itself.
Acoustically Insulated For Quieter Flush
The regular tank and bowl toilets are notorious for producing noise during a flush. The in-wall tank system however, are quieter due to the tank being inside the wall.
With the tank wrapped in an insulating cover which prevent condensation, it is also acoustically insulated. And with the wall acting as a sound barrier, flushing operation is exceptionally quiet.
Features & Specifications Overview
How Much Will A Complete System Costs?
The Aquia CT418FG#01 is the model number for the bowl only. You will need the in-wall tank system to make it work as a complete toilet. Then there’s the seat cover and push plate which you have to buy them all separately.
So for a basic system, you will need to buy:
- The bowl (with SanaGloss), model: CT418FG#01
- SoftClose seat cover, model: SS114#01
- DuoFit In-Wall Tank System, model: WT151M
- Push Plate Dual Button, model: YT800#WH
Just the basic system would cost you at least $600, assuming it includes free shipping.
You will probably need a budget of about $1000 for the installation.
So all in all, expect a total cost of anything between $1600 to $2000 for a complete wall hung toilet installation. And remember, that’s only for a basic system.
Of course you can save around $50 if you choose a bowl without the SanaGloss finish. Any other options will only see the prices go up from there.
Aquia Versus Maris – How Would You Choose?
As mentioned earlier, TOTO USA has only 2 models for its wall hung toilet bowls – Aquia and Maris.
Both have SanaGloss finish and they are different in dimension and water surface area.
The Maris (model: CT486FG#01) is longer in length by an inch at 22.06″. As compare to the Aquia which is 21.06″ long. An inch may not seem like an issue in most cases. But if space is really tight, every inch counts.
If you have a really small bathroom, then the Aquia will be a more suitable model to go for.
The space for the Maris bowl is 30″ x 43″ to meet the minimum space rule. But please check the local plumbing code for the minimum space requirement. In most States, it should be acceptable.
Other than the dimensional size, the bowl design is another factor you should look out. Especially if you are a large build, you may find yourself edging towards the front. And if you compare the bowl shape of the Maris vs the Aquia, you will notice that the bowl front of the Maris is a curved-in. (see diagram below)
Guys who are ‘long’ is likely going to hit the inside bowl surface. And yes, there are already complaints of such nature with the Maris.
The next thing you should know is the smaller water surface area of the Maris bowl. You will learn why this is an issue in the next section.

What Are The Options For The In-Wall Tank System?
The heart of this TOTO Aquia Wall Hung toilet is the in-wall tank system. Without it, the Aquia bowl is just a piece of porcelain ware that serves no purpose.
But what is a good in-wall tank system and what are the options available out there?
Besides TOTO’s DUOFIT in-wall tank system, you have the Geberit option. Of course there are other in-wall frames you can use, but for a peace of mind, always go for the best.
A good in-wall tank and carrier must have this 2 features:
- A one-piece insulated impact-resistant high density polyethylene (HDPE) tank. The TOTO DUOFIT and Geberit Duofix tank are blow molded with no seams or weak points. Thereby eliminating any possibility of leakage.
- A metal frame structure of at least 16-gauge and powder coated. The frame must meet the ASME A112.6.2* requirement. Which in this case, both the TOTO and Geberit frame is able to support up to 880 lbs, exceeding the minimum strength requirement of ASME A112.6.2.
*ASME A112.6.2 is a standard for Framing-Affixed Supports for Off-The-Floor Water Closets with Concealed Tanks.
There are almost no differences between the DUOFIT and Geberit. In fact, they look so similar that many think TOTO could have simply used their logo on the Geberit system.
But don’t worry, there’s no legal issues here. It’s normal for one company to use another manufacturer’s components through an OEM agreement. So likely there’s an agreement between TOTO and Geberit. In fact, Geberit also produces the in-wall tank and carrier for other brands like KOHLER and Duravit.
Whatever it is, you are good with both brands. However, between the 2, Geberit is better known than TOTO for its in-wall tank and carrier system. And it produces some of the best wall hung toilet frame for a long list of toilet manufacturers besides TOTO.
So between Geberit Duofix and TOTO DUOFIT, how should you choose?
When all things are equal, price becomes the basis of your decision. But there’s another consideration you may have besides price. That is the choice of push plates available.
TOTO DUOFIT system provides only 3 options, versus Geberit’s endless choice of push plates. But some of the Geberit push plates can cost more than the in-wall carrier itself. And it’s not necessary for an aesthetic reason. Geberit has a pneumatic range which also caters for ADA compliant solutions.
What Are The Disadvantages You Should Know?
When all looks good on the surface, there’s this little shortcoming that you should be aware of. That is the small water surface area of this TOTO Aquia Wall Hung toilet.
With an area of just 5.5″ x 4.75″, it poses quite a problem with bowl streaking and odor.
When you have a heavy session, the water volume is just too small to get everything submerge. The wastes that are above the water will cause odor to fill the air around. Which is why you need an exhaust fan if you have a really small space for a toilet like this.
And, all the more you need the SanaGloss coat on the bowl surface. It’s inevitable for waste to stick to the surface with a small water surface area. The SanaGloss surface will ensure the wastes are easily flushed away. Otherwise over time skid marks may start to form around the bowl outlet.
But this is not a design flaw. It’s typical of all washdown toilets to have small water surface area.
So if you are used to having a large water surface area, this will be the only thing you need to get use to.
Another disadvantage is the limited color choice of the TOTO Aquia Wall Hung toilet.
If your idea of ‘hiding’ the unsightly streaks is with a darker color bowl, such as a Black or Ebony bowl, you can’t. This TOTO Aquia Wall Hung toilet is available only in White.
But the biggest disadvantage of all for many, is the high price tag. This is to be expected as the bulk of the cost goes to installation. Which include the supplementary materials like wall studs, plasters or tiles and labor. And they can all add up to quite a substantial amount.
Can You Save On Installation Cost?
The only way you can save on the installation cost is to install this TOTO Aquia Wall Hung toilet yourself. But that is assuming you have the knowledge and experience in putting up partition walls and plumbing. Otherwise it is best to engage a plumbing company which has a good track record in installing wall hung toilets.
The main thing here is securing the carrier frame within the wall. Even though the carrier is rated to carry up to 880 lbs, that doesn’t mean it will as long as it is fastened to the wall. The loading strength of the in-wall carrier is as good as how rigid the wall is. So it’s pointless if the wall can’t support any thing more than 880 lbs or less.
Some Concerns People Have About Wall Mounted Toilet
It’s not uncommon to read how people are still skeptical about wall mounted toilets. The main concern is how strong the in-wall frame can be, and how will it last.
The thought of a loosen commode come crashing down while you are on it is enough to draw some white knuckles. But relax, nothing of that sort will happen if it’s properly installed.
There are many cases of a wall hung toilet lasting for as long as 30 years without a glitch. And in Switzerland alone, over 85% of toilets installed are wall hung. So there’s nothing to worry about as far as safety is concerned.
And not forgetting the American Society of Mechanical Engineers or ASME has a standard that governs the safety for wall mounted toilet. The ASME A112.6.2 specifically deals with the framing-affixed supports for all off-the-floor water closets with concealed tanks.
Another concern is the ease of replacing parts.
Since the tank is hidden behind wall, you can’t expect the same convenience of a regular toilet. But they are not difficult to access the innards as well when you need to replace any parts.
The large flush actuator plate that holds the button can be removed for easy access to the internal tank. Except the tank, you can replace every thing that are damage or worn out through the push plate opening.
So whether you are replacing the flush valve or fill valve, they can be done through the open flush plate hole. And you can also make adjustment to the water level in the tank. Pretty much the same maintenance like you would do with a regular toilet.
Can You Replace A Floor Mount Toilet With The TOTO Aquia CT418FG? And How?
The short answer is Yes, you can. That’s when you have a generous budget, and are ready to endure several days of inconvenience.
This is because it will involve some massive retrofitting to your bathroom. You will need to re-route the drain pipe from the floor to the wall to connect to the stack.
And you need to construct a stud wall from the floor to the ceiling to support your wall mount. That will involve considerable hacking, plastering and tiling of the floor and wall. And of course re-piping of water supply line. Definitely not in a day’s work.
The best time to install a wall hung toilet is when you are remodeling your bathroom, or a new build.
The customer reviews are not in good numbers. With less than 100 reviews for both the Aquia bowl and the DUOFIT In-Wall tank system.
At publishing time, the total reviews for the Aquia bowl is at 55 with an average star rating of 4.6 out of 5 stars. While the DUOFIT tank carrier (WT151M) can only manage a 4.0 stars with 9 reviews in total. And the WT152M model gets a 4.1 stars with 14 reviews.
In comparison, the Geberit 111.335.00.5 has a better rating of 4.7 stars with 34 reviews.
From the low review numbers, it shows the wall hung toilet is still a less popular option. By and large, Americans are still skeptical about the reliability and safety despite its widespread use in Europe.
But if you were to compare to 5 years ago, you should notice an upward trend for wall hung toilet. This is a clear sign of growing acceptance and the numbers will continue to scale up in the next 5 years.

Why Geberit Is Your Best Option For In-Wall Tank System
If you are still contemplating on which system to go for, consider the Geberit Duofix 111.335.00.5 carrier.
- The price is lower, or rather the lowest.
- It’s a narrower frame so it takes up lesser wall real estate. Especially for a small toilet cubicle, this is life saving.
- This 2 x 6 inch carrier allows more air space around the tank compare to the 2 x 4 inch frame. This should reduce the possibility of condensation further besides the already insulated tank.
- Geberit’s installation manual is way more comprehensive than TOTO’s. No guessing needed.
- And with a lifetime warranty for its tank and carrier and 10 year warranty on fill valve and flush valve, do you need to even think?
- Lower average water consumption compare to TOTO’s 1.28 gpf.
