What to expect when installing a wall mounted toilet?

The most common parts included with this type of installation include a cistern, pipes, flexible water inlet hose, actuator plates, fixing mounts and screws, isolation valve, inspection shaft, waste adapter, bowl, seat, and the frame that holds the tank. Most builds will require an in wall carrier system to be in place.

If you're not experienced with DIY or fixing things yourself, installing one of these can be quite an arduous and time consuming task in comparison to a floor mounted option. There are lots of different parts which can be quite confusing for a beginner. For that reason we recommend hiring a plumbing professional. If however, you want to do it yourself, here is a video from GROHE, which explains the general work involved. These instructions will change for each individual model and brand, and should only be used as an example.

Wall hung vs floor mounted toilet

We don't believe one is superior to the other. However, there are specific use cases where one may be more beneficial to you than the other. We look at a few such examples below. Alternatively, here are some Pros and Cons to get you started.


Building codes - Because they are quite small in their design, and quite flexible in how and where you can install them, they provide an alternative solution which may be better suited to meeting building codes and clearances than a floor based one. For example, you may have a set distance you have to meet in terms of how much floor space is available in front of the bowl. Because the tank is placed in the wall, it will not protrude as far. The same applies to the seating height, you can move it further up, or lower it, meeting ADA height requirements in the process.

Aesthetics - It can be argued that hanging toilets are more aesthetic. The missing tank, and the floating style, all contribute to this to give them a minimalistic theme that usually looks great.

Easy to clean - Their bowls are often equipped with smooth sides and edges with no gaps for bacteria to hide in. This helps with maintenance tasks and ensures cleaning is simple.

Small washrooms - If you've got space limitations, they can be a sensible solution to save floor space and give users more leg room. Comfort is important, and ensuring you don't feel cramped contributes to this.


Price - The hardware and plumbing fixtures alone are more expensive than the majority of floor mounted toilets. Furthermore, the cost to have it fitted by a plumber can drive this up further, which in most cases, will be necessary.

Thick walls - In most cases, it will require thicker walls to fit the carrier and tank. Not every home has this luxury, which can often mean expensive renovation is required in order to rectify it.

Detailed analysis of the chosen products pros and cons can be found below. We look at both the internal and external features, flush, shapes, sizes, and much more.

KOHLER Veil K-6299-0

The Veil K-6299-0 comes from a reputable brand name. It's designed for those going for a more basic, simple design. The smooth curves of the bowl look great, and you have some decent variety in the colors you choose too.

As mentioned at the beginning of this guide, this isn't the full package, but rather the bowl part. You will need to combine this with the framework of the K-6284 that gets hidden within the walls. So be aware of the extra costs involved in this, and set your budget accordingly. The nature of these designs, and the expertise they require for setting them up, often means we can't suggest this as a viable option for people with a low budget.

However, for those not too concerned with the price tag, the advantages are clear to see. It's versatile in where it can be placed, and how high you sit. Meaning you can ensure it meets ADA seating height criteria.

It also ensures you save precious floor space in more compact environments. In fact, in comparison with KOHLER's longest protruding bowls, you can save an impressive twelve inches. This can have a significant impact just not on the amount of leg room you have, but how spacious the bathroom as a whole feels.

The tank mechanism it's designed to utilize once all the parts are put together is dual flush. A 0.8 GPF rate for liquids, and 1.6 GPF rate for solids. When used sensibly, this can make all the difference in how much water your household consumes every year.

Toto Aquia CT418FG#01

Similarly to the K-6299 above, the Aquia CT418FG#01 is from a household name in the toilet industry, a name that has built plenty of bathroom fixtures that have been well recieved across the board.

And like the above, it will also need to be paired with a carrier system that holds the tank behind a wall. There are options specifically made by Toto to do this, or if you prefer, you can use a different make. You will also need to buy the seat and button separately. For the seat, we recommend going with a soft close option. The SS204 or SS114 are both compatible here.

The bowl itself has an elongated shape, designed to maximize user comfort and improve the leg space through a more natural, better seated posture.

Once all the fixtures are purchased, you can expect a dual flush system that doesn't consume much water. In fact, the lighter flush uses just 0.9 gallons, and the heavier one uses 1.6 gallons.

The dimensions are 23.8 inches by 15.8 inches by 17.5 inches and it weighs 66.5 lbs. It has a smooth, easy to clean surface, made in ceramic and is finished in a bright cotton color.

After looking at various sources and online shops, the majority of feedback from consumers is positive at the time of writing. A very good sign, and an early indicator that the product is reliable and effective. Of course, you can't judge something by customer reports alone, but it is an important part of our research process.

Swiss Madison St Tropez

The St Tropez from Swiss Madison features a stunning exterior with a skirted bowl that could be clasified as elongated, bordering on rectangular. It's finished in a bright white and has the design to meet most modern interior styles.

Just to remind our readers once again, this is the bowl only. The carrier frame should be purchased separately. It is compatible with several different carriers, so you have a bit of choice in that department.

When you bring each part together however, you have a toilet that operates on a dual flushing mechanism that has great water conservation properties, meeting Watersense criteria with 0.8 and 1.28 GPF rates.

The seat is included in the price, and it has quiet closing hinges to stop slams, and it has a quick release function which enables it to be removed quickly for cleaning purposes.

It's ADA compliant too, meeting customers seating height requirements and making sure the majority of users bathroom needs are met.

Making sure you have respectable coverage for when things go wrong is important too. This model has a limited lifetime warranty policy in place just in case.

While it may not have the same brand recognition as the others, this could be a good alternative, especially if visuals play an important role in your decision.

Duravit Starck 3 2226090092

The Starck 3 shares several similarities with its competitors above. Namely a concealed cistern, and the ability to use a different in wall frame for the tank.

It will utilize a two flush system to remove waste from the bowl, sending between 0.8 gallons and 1.6 gallons depending on the waste that needs to be disposed. Combined together, this ensures your household can save a significant amount of water per year, and also enables it to meet EPA WaterSense standards.

You also have the ability to install it at a height between seventeen and nineteen inches to meet the standards of the Americans With Disabilities Act. Floor mounts don't have this choice. You either buy a specific bowl size, which can cost more, or you go with a standard size.

However, as far as budgetting is concerned, you will need to make sure that you're aware that a seat isn't included. You can purchase one separately, be it soft close, or the SensoWash, which is a bidet that is compatible with it.

Its dimensions are 14.6 inches by 24.4 inches by 22.5 inches and it weighs 63.9 pounds.

Overall, we feel this has several great attributes that make it suitable for a residential setting. It's aesthetic, easy to maintain, and efficient.

Other things to consider

Bathroom size - Think about where your toilet will be installed and its surrounding hardware, for example the vanities. You need to plan ahead to make sure you've got sufficient space for sitting and standing, without feeling too enclosed. Sometimes, a minimalistic theme is the best route to take.

If you don't have much choice because your washroom is so compact, then you may want to opt for models equipped with a round front bowl as they tend to keep your back closer to the wall, giving more leg room to do your business.

Brand - Both Kohler and Toto hanging toilets are certainly brand names that we rate highly. They often come with strong flushing power that rinses the bowl thoroughly and effectivly. They are also known to provide several models that meet WaterSense standards, saving consumers water and money over the years of ownership.

However, if you're wanting the full picture, we recommend checking out what Duravit, EAGO, Mansfield, WoodBridge, Icera, and American Standard have on offer too. All of these are respectable companies in this industry, with plenty of highly rated products.

Type of flush - For us, it all boils down to a dual or single flushing mechanism. We've got a guide that explains the advantages of owning a dual flush toilet here. However, single flush systems have advantages of their own and should certainly be taken into consideration. Whichever mechanism you pick, we recommend sticking with WaterSense labelled products simply because they're the more sensible choice for people wanting to protect the environment and save water.

How much water does it use? - If you're someone who's aware of the amount of water the average household uses over the course of the year, in particular the bathroom, you will appreciate why low flow toilets are favored by many and increasing in popularity. Compared to the standard 1.6 gallon models, these low flowing options will use just 1.28 gallons per flush, or even less. Over a long period of time, this can make a significant dent in how much your water bills are, and in some cases, make you eligiblefor tax rebates. Look for the WaterSense sticker from the EPA.

Water surface - Think about the width and length of the water spot at the bottom of the bowl. It should be reasonably large as it plays a part in keeping smells down, and allows waste to pass through the trapway easier with less staining and sticking. All of which promote a healthier, more hygienic environment for everyone. Just remember, the larger the surface is, the higher the water sits in the bowl. You don't want a product where the water level is only a couple of inches away from the rim. Splashing is the least of your problems in that scenario. We go into more detail about this on our home page.

Seat - When inspecting the specifications, one of the first things to check is the accessories that come as part of the package. This includes things like the water supply line and seat. It's quite common for manufacturers to leave out the seat, making consumers to shop for one separately. The last thing you want to happen is to spend a week waiting for your delivery, set everything up, then find out it didn't come with a seat.

If it becomes apparent that your seat isnt included in the price, you'll want to ensure you get yourself a soft closing one at the very minimum. This helps prevent it from slamming shut after use.

You're not just limited to the simple designs either, you could also make the decision to go with a bidet seat, which enables users to clean themselves with a built in spray with several functions inclusding power and warmth. MThis is a far more hygienic than paper, but it is also more expensive.

Glazing - Ensure the product you choose has the appropriate ceramic protection in place. When talking about protecting the china, we usually refer to the type of glazing or anti bacterial coating it has. This is designed to reduce the build up of germs and odors. It makes the surface of the bowl slicker, making it harder for any kind of staining to take place, and ensure the bathroom smells fresh for longer.

MaP score - When it comes to performance, how much waste a toilet handles is obviously high on most peoples list of priorities. But how do we separate the poorly performing options from the powerful? One such method is to utilize the scoring system offered in MaP ratings. They provide a simple scale between zero and a thousand, letting users know how many grams of waste a model can flush in one go. Anything that hovers around the 1k mark, you can expect top tier performance. However, you will occasionally come across products with a 300 grams score and below. These should be avoided, as they aren't going to provide the necessary power to clear the bowl of waste.

Budget - Because there may be considerable costs involved with fitting a wall hung unit, you need to ensure you've planned ahead and taken into account not just the toilet bowl and tank costs, but also the price of a plumber and any building contractors to ensure you can fit it within your washrooms walls. All of these things can add up quickly, so it's vital to research this beforehand.

Consumer feedback - While star ratings may give you a rough idea about the quality of the product, it doesn't give the full picture. For example, you may see that the majority of feedback provided sings it praises. However, if there is a number of people reporting a similar problem or fault, then it may be a smart decision to avoid purchasing it. Who knows when that defect will strike next, it may be yours. With plenty of reliable options available from reputable brands, there is no need to take such a risk. So, spend some time researching a little deeper into what other people are reporting as they often provide valuable insight from people with first hand experience.


You'll find that residential wall mounted toilets aren't very common. Most households bathrooms will have floor mounted products installed. So, if you're after something a bit different to the rest, one of the models above could be a great match for your home. Just be aware that there may be a bit of extra DIY and renovation involved. If you're not an expert in this field, hiring a professional to do it for you will eat into your budget.
