Wall-hung toilets fit perfectly into contemporary-style bathrooms as you only see the bits you need to clean: the pan, lid and flush button. Beyond these parts, the whole mechanism is hidden behind casing and supported by a toilet frame. Read on for all you need to know about picking the right frame for your toilet!

Features of wall-hung toilets


Classic close-coupled toilets are cost-effective and easy to install. While wall-hung toilets may be a little more complicated to fit, they do offer a sharper look and are more hygienic. If you're trying to choose between the two options, you should consider that a wall-hung toilet will require you to make a few decisions, including:

  • choosing a frame based on the wall and floor fixings, bearing in mind that this option won't be possible if you have both wooden walls and flooring;
  • deciding on a type of casing to cover the frame. Your options include tiled, painted, plasterboard, glass or ready-made casings (fibreglass, for example). Your choice will depend on frame requirements, as well as your own tastes and budget;
  • settling on any optional accessories you may require for enchancing toilet pan hygiene.
It's also worth noting that any type of repair or maintenance work carried out on a wall-hung toilet will be trickier and more expensive than for traditional models. However, mid- to high-end wall-hung toilet kits do offer high quality and reliability for more peace of mind.

Wall-hung toilets also offer the following benefits: 
  • unbeatable hygiene standards;
  • easier acess for those with reduced mobility;
  • user comfort and less noise;
  • a wide range of designs to choose from.

Made-to-measure comfort and installation 

Wall-hung toilets offer increased comfort:

  • The height of the toilet pan is adjustable: this is essential for anyone well above or below average height. The support frame allows you to install the pan at various heights that would not be possible with a conventional toilet. The seat height can be decided upon during installation. A standard position, for example, is around 45 cm from the finished floor while a height of 50 cm will ensure user comfort for elderly people or those with disabilities.
  • Wall-hung toilets are quieter than close-coupled toilets as the flush and refill mechanism is enclosed within the frame casing. This means you won't be disturbed in the middle of the night by the sound of rushing water!

Efficient cleaning for better hygiene

The design of these toilets also offers improved hygiene standards:
  • the absence of a water supply line means less surface for dust to gather;
  • the hanging toilet bowl makes cleaning more straightforward as it is easier to access.

Additional options for wall-hung toilets

There are a number of additional options designed to make cleaning easier:
  • ceramic toilet rim with an anti-limescale treatment;
  • a rimless toilet bowl to prevent bacteria growth and optimise cleaning;
  • an anti-limescale toilet pan to prevent the appearance of limescale;
  • a removable toilet seat for easier maintenance.
Finally, consider any standards in place in your country designed to guarantee waste drainage efficiency, the resistance of your toilet to cleaning products, standard dimensions for the various component connections, the strength of the toilet lid and the reliability of the flush mechanism.

Choosing a frame for your wall-hung toilet

Toilet fixing frames are metal structures that serve as skeletons. Theu support not only the toilet pan, but also the flush mechanism, the pipes, the flush button or plate and the casing, which is designed to improve the appearance of your wall-hung toilet.

There are three types of support frame: wall, floor and universal. Your choice will depend on the surface of your bathroom floor and walls:
  • Wall frames are usually attached to a masonry, brick or breezeblock supporting wall;
  • Floor frames sit directly on the floor, which must therefore be made of concrete to ensure stability;
  • Universal mounting brackets can be fixed to both walls and floors. This assembly offers a much more robust and stable support than the other two types. It is the method usually used in installations in new-builds and for renovation work.

Installation conditions for toilet frames

Toilet frames cannot be installed if you have:
  • Plasterboard walls;
  • Wooden walls and floors.
It is possible to install toilet frames on wooden floors. However, it is recommended to strengthen the spot where the toilet frame will sit

If your wall is coated with plasterboard, you'll need to attach the support frame directly to the masonry behind, i.e. remove part or all of the plasterboard in order to reach the brick or breezeblock.

Choosing a casing type for your toilet frame

Depending on the layout and design of your bathroom or toilet, there are two main options available to you: you can build the frame directly in the wall or cover it with some kind of casing. This casing comes in a variety of finishes, such as tile or paint. The sky's the limit when it comes to choosing a type!

Tiled to ready-made casings



  • Glass casing is a high-end option that offers easy cleaning and a slick design.
  • Toilet frame units are handy for storing cleaning products.
  • Standard or ready-made casing offers easy installation. However, the toilet pan will be fixed at the standard height of 45 cm.
  • Ready-to-tile casing is suitable for all types of support frame. The pan will be fixed at a comfortable height of 50 cm. However, this can also be cut down to a standard height of 45 cm.
  • Frame built into the wall, only the toilet pan and the flush plate of your wall-hung toilet will be left on show. However, you may still lose space above the cistern. This system usually involves painted plasterboard.Plasterboard casing allows for all possible types of installation and can incorporate shelves or storage space above the cistern.

Please note
: the flush mechanism must always be accessible by removing the front panel. Be sure to also leave the water supply and drainage pipes accessible (i.e. via a hatch). Some forms of casing are equipped with a handy removable side panel. Unfortunately, leaks are always possible so you want to be able to carry out repairs without having to break the casing covering your wall-hung toilet.

Installing a wall-hung toilet frame

If your DIY expertise extends to changing a light bulb or if your only tool is a Swiss army knife... you're best off having a professional install your wall-hung toilet.

While you will only require fairly standard tools (spanners, screwdrivers, drills, spirit level etc.), installing a wall-hung toilet requires a certain amount of know-how. Certain regulations must be followed regarding:

  • The minimum slope of the soil pipe for good drainage;
  • Water inlet and waste water outflow connections;
  • Securing the frame and installing a removable hatch.

Installing a wall-hung toilet involves so many separate components that forgetting one or failing to follow installation guidelines can have serious consequences for your home.

Remember that if you live in a block of flats, a water leak might be felt by your neighbours before you notice it yourself! It is therefore essential to ensure your pipes can be easily accessed!

Standard dimensions for toilet fixing frames

Height, width and depth of wall-hung toilets




Toilet fixing frames tend to stick to the following dimensions:
  • a width of 50 cm;
  • a standard height of 112 cm;
  • a reduced height of 82 cm for some models;
  • a depth of less than 20 cm;
  • an adjustable toilet pan height of:
    • 30 cm for children;
    • 40 cm for normal usage;
    • 50 cm for people with reduced mobility.
Please note that these are overall dimensions. For a more precise idea of how much space your frame will take up, you will have to add a few centimetres to these measurements (depending on the casing type you choose). 

Toilet frame quality and optional extras

High-end finishes for wall-hung toilets

The range of options and quality of finish for wall-hung toilets may vary from model to model, in terms of the following:
  • Digital sensor flush, simply wave your hand in front of the toilet to trigger the flush!
  • Quality of inlet valve and flush mechanism;
  • Option to incorporate a macerator pump;
  • Optional connections to other bathroom units, such as a bidet or sink;
  • Type of water release in pan (more efficient for high-end models);
  • Format of the frame itself.

As with any product, entry-level frames can range in quality, which could lead to issues regarding:

  • The toilet pan and flow of pressurised water;
  • Quality of washers and other seals;
  • The fill mechanism;
  • Availability of spare parts in case of damage or wear

Generally speaking, the frame itself tends to be quite robust and is unlikely to present problems.

While it's not worth being paranoid, bear in mind that price differences between products are often justified; known brands offer the guarantee of quality and customer care.

Now it's time to get your overalls on!

A chemist by training and a self-taught handyman, I work in the pharmaceutical industry. As a young dad of 36 years, tinkering is like breathing to me: in short, I am a jack-of-all-trades.

To my credit, I have already completed 5 kitchen installs, a renovated apartment, and an extension on my own house (for financial reasons, my wife and I have chosen the closed-cover option for wooden house extension). Over the last three years I have done everything: insulation, plasterboard, electrical, patching, painting, parquet, dressing, bathroom, tile...in short, 60 m2, made entirely with my own two hands.

Fortunately, I have my own personal decorator. I don’t worry about styles and colors. As they say: happy wife, happy life.

My motto: good tools and good products are half the work, the rest is patience and meticulousness. To your keyboards. The good advice is here.
