Wall-Mounted Toilets-Pros, Cons & Buyer Guide

Last Updated on May 18, 2022 by toilethaven

A wall-mounted toilet, also known as a wall-hung toilet is a toilet that is mounted on the bathroom wall. Only the bowl is visible, as the toilet tank is concealed inside the bathroom wall.

A frame called a carrier is used to support the toilet tank and also for hooking up the bowl. To conceal the tank and the carrier, a secondary wall is erected in the bathroom.

So, how good are wall-mounted toilets? Are they practical?

The main advantage of wall-hung/mounted toilets is how stylish they look. They also give you the option to install them at any height you want which cannot be achieved with other toilets. Cleaning them is also super easy.

The main disadvantage of wall-mounted toilets is the cost of installation. The cost of installing a wall-hung toilet exceeds the cost of the toilet itself and unlike floor-mounted toilets which you can install on your own they need to be installed by an expert, which is not cheap.

Wall-mounted toilets also have a weight limit. The minimum weight limit of a wall-mounted toilet is 500 pounds. Luckily, that is more than sufficient for most people.

Let us now look at wall-mounted toilets in more details.

How Does a Wall-Mounted Toilet Work?

wall-hung toilet

Wall-mounted toilets are not as popular in the United States as they are in Europe but they are catching up, just like bidets. A wall-hung toilet has 3 main components:

  • Bowl
  • Tank
  • Carrier

The carrier which is made of solid steel provides sufficient support to carry the tank and also anchor the bowl. Wall-mounted toilets are not necessarily very expensive but when you factor in the cost of the carrier and installation then the price moves up tremendously.

They are however very sleek and stylish. So, how does a wall-mounted toilet work?

After the carrier and toilet tank have been installed on the bathroom wall, a secondary wall is erected to hide them. 3 precise openings are made on this wall.

The first opening is the flush button panel. This is where you will be flushing your toilet from. It also provides access to the toilet tank incase you need to check or repair something.

The second opening is where flush water will flow from the tank to the bowl. Below this opening is a larger opening which is the outlet pipe. Waste from the toilet bowl will exit from a pipe installed on that opening.

Wall-hung toilets can either be gravity-flushed or pressure-assisted. The gravity flush toilets depends on gravity between the tank and the bowl to flush the toilet while the pressure-assisted wall-mounted toilets use water under high pressure from a secondary tank in the main toilet tank.

In floor-mounted toilets, there is either comfort height or standard height toilets. The toilet bowl height of wall-hung toilet can be adjusted (during installation) so that you will be sitting at your most comfortable height.

The minimum weight limit of wall-mounted toilets is 500 pounds as required by the United States’ National Consensus Standards. Toto Aquia wall-hung toilet has among the highest minimum weight limit of 800 pounds.

Wall-Hung vs Floor-Mounted Toilets

Floor-mounted or free standing toilets are toilets that are installed on the bathroom floor. The floor-mounted toilets can be one-piece-toilets, two-piece toilets, tankless toilets etc.

So, between wall-hung toilets and floor-mounted toilets which ones are better? Or rather, what is the pros and cons of wall-mounted vs floor-mounted toilets?

Lets then look at the differences between wall-mounted and floor mounted toilets and also their advantages and disadvantages.

The Pros and Cons of Wall-Mounted Toilets



  • Saves Space.
  • Are Stylish and Elegant.
  • Installed to suit user’s height preference.
  • Easy to Clean.
  • Cheaper than high end floor-mounted toilets.


  • Expensive installation.
  • Costly repairs.
  • Difficult to install.

The Pros and Cons of Floor-Mounted Toilets


  • They are cheaper.
  • Are easier to install.
  • Cheap to repair.


  • Take up more space.
  • Old-fashioned.
  • Harder to clean.
  • Height cannot be adjusted.

Wall-Mounted vs Floor-Mounted Toilets

1. Space

Wall-mounted toilets are hung on the bathroom wall with their toilet tanks/cisterns concealed in the wall. They are therefore more space-economic than their floor-mounted counterparts.

Due to their small size, wall-mounted toilets are great toilets for small bathrooms or anyone else who doesn’t want to have their bathroom looking stuffy. A bathroom with a lot of free space is every homeowner’s dream.

Floor-mounted toilets take up more bathroom space in the than wall-hung toilets because you will need to accommodate both the toilet bowl and the tank. This can limit your comfort in the bathroom especially if the vanity or bathroom sink are too close to the toilet.

More space efficient floor-mounted toilets are the compact elongated toilets or round-front toilets but still take up more space compared to wall-hung toilets.

Let us see the difference in size between one popular wall-mounted toilet and a popular floor-mounted toilet.

  • Toto Aquia Wall-Hung Toilet

Toilet dimensions: 21-1/16 x 14 3/16 x 15 inch

  • Toto Drake Floor-Mounted Toilet

Toilet Dimension: 28 x 19.5 x 30.5 inches

2. Cost

Wall-mounted toilets costs more than most floor-mounted toilets.  Using the example above, the Toto Aquia wall-hung toilet costs a couple of hundred dollars more than the Toto Drake floor-mounted toilet.

This is not to however mean that floor mounted toilets are cheap. To put this into perspective, consider the Kohler Veil intelligent floor mounted toilet which costs hundreds of dollars more than the Kohler Veil wall-hung toilet.

Another important aspect of cost is the cost of installation. As a matter of fact, it is very easy to install a floor-mounted toilet on your own. A Wall-hung toilet will definitely need to be installed by a professional plumber and it will be expensive.

Apart from the cost of the toilet and plumbing, you will also need to buy the toilet carrier. The carrier is the frame mounted on the toilet to hang the toilet and carry the tank.

3. Style and Design

Wall-mounted toilets are so stylish and beautiful. A bathroom with a wall-mounted toilet will without a doubt stand out.

Floor-mounted toilets can be a bit boring are seen more as a means to end more than a statement of style. This is because people have seen floor-mounted toilets for generations and there is nothing to “wow!” about.

Not all floor-mounted toilets are old-fashioned though. Smart and tankless toilets like the Kohler Veil or Ove Decors which are floor-mounted will give the most elegant wall-mounted toilets a run for their money.

4. Ease of Cleaning

Cleaning a wall-mounted toilet is a cinch. There is no toilet tanks and toilet bowl bases to think about. There are very few crevices if any which means you will spend less time every time you clean your toilet.

Floor mounted toilets on the other hand have so many nooks and crannies that you must take your time to go through while cleaning lest germs pitch camp there. This is especially the case if you have a two-piece toilet.

All is not groom though for floor-mounted toilets. Modern one-piece toilets are skirted (have a concealed trapway) which means cleaning is way easier than their two-piece non-skirted counterparts

5. Ease of installation

This is where the wall-mounted toilets get a beating. This toilets’ tanks are concealed in the bathroom wall. This means the bathroom wall has to be redesigned to accommodate the toilet tank. It involves installation of a carrier and a thicker wall called the ledge wall.

With a floor-mounted toilet, you only need the toilet drainpipe to be in place and you are set to go. Most people who buy floor-mounted toilets actually don’t call plumbers to install them. It is a simple DIY.

6. Height.

Among the best advantages of wall-mounted toilets is that it gives the buyer the option of installing it at their preferred heights. For instance, the Toto Aquia wall-hung toilet has a height range of between 15 and 19 inches.

Floor-mounted toilets on the other hand come in either standard height or comfort height. It is however not such a terrible thing since you can always use a toilet seat riser to add extra height to your toilet.

A 2 inch toilet seat riser can easily convert a standard height toilet into a comfort height toilet. Toilet seat risers go up to 6 inch in height and include toilet seat risers with arms and toilet seat risers with a safety frame. Raised toilet seats as they are also called are portable which makes them more versatile.

What are The Best Wall-Mounted Toilets?

These are among the best wall-hung/ wall-mounted toilet you can buy:

1. Toto Aquia wall-hung toilet



This a dual flush elongated wall-hung toilet that is coated with Toto’s Cefiontect glaze to inhibit dirt adherence. It does not come with a a toilet seat hence you will need to buy one separately.

You can either choose an ordinary toilet seat or a bidet seat either from Toto or other manufacturers for extra comfort.

2. Kohler Veil wall-hung toilet


The Kohler K-6299-0 Veil is an elongated wall-hung toilet that is made so compact to occupy a small bathroom space. It should however not be confused with Kohler Veil intelligent wall-hung toilet.

Kohler Veil intelligent wall-hung toilet is a smart toilet which costs way more than the above model. If you have the cash then by all means go for it.

3. Swiss Madison Well Made Forever Ivy wall-hung toilet



The Swiss Madison Well Made Forever Ivy toilet is a dual flush (0.8/1.28 gallons per flush) elongated wall-hung toilet that is both sleek and competitively priced.

It comes with a soft close toilet which also has the quick-release mechanism for quicker and thorough cleaning.

Wall-Mounted Toilet Problems

It is not all rosy for wall-mounted toilets. They too like floor mounted toilets occasionally have a few problems from time to time. Some of these problems include:

1. A wobbly wall-mounted toilets

A wall-mounted toilet can accommodate a great deal of weight but some time the fixtures mounting these toilets to the wall can become loose resulting into a wobbly/rocking toilet. A wobbly toilet whether floor-mounted or wall-mounted is uncomfortable and even risky especially to old folk.

The best thing is to remove the toilet then reinstall and tighten the fixtures or replace some which might be worn out. You can do this on your own or you could call in a plumber.

2. A leaking Wall-Mounted Toilet

When a wall-mounted toilet leaks when flushed, it means the plumbing works were not well done or the toilet seal is not sealing anymore.

A leaking wall-mounted toilet is characterized by a wet bathroom wall where the toilet is installed. This can become a big problem if not addressed forthwith because the wall paint will start to peel off and also encourage the growth of mold.

3. A Running Wall-Mounted Toilet

When a wall-mounted toilet is continuously running, just like a floor-mounted it points out to a defective fill valve, toilet flapper or a toilet float that is not properly adjusted. A running toilet is a very expensive thing to have.

The best thing to do is call in a plumber to determine what the problem is. If the toilet fill valve needs replacement or the float needs to be adjusted, he should be able to do it without a problem.

Wall-Mounted Toilet Installation

How do you install a wall-mounted toilet? Unfortunately, wall-hung toilets are not as easy to install as floor-mounted toilets.

I would not advise you to attempt a wall-mounted toilet installation DIY unless you are exception plumbing experience. As a matter of fact, not all plumbers can install a wall-hung toilet.

Wall-mounted toilets originated in Europe but the idea has spread all over the world and United States has not been left behind. Before, these toilets were only seen in affluent establishments but they are now more common in private homes. The biggest challenge with the wall-mounted toilets is the installation since not all plumbers are well conversant with them and the costs tends to be therefore high. The end product is however amazing and you could say the end justifies the means.
