How to Install Wall-Hung Toilets & Bidets: A Step-by-Step Guide 2026

Wall-hung sanitary fixtures offer several advantages, including a smaller footprint, better hygiene (since cleaning the floor is easier with the suspension), and a monolithic look for the flooring itself.

When installing wall-hung fixtures on a drywall false wall, the approximately 15 cm ledge left mid-wall provides a convenient shelf for bathroom products. Thanks to pre-assembled systems, installing wall-hung fixtures is simplified and quick: the WC module can already contain the flush tank, the brackets for suspending the bowl, and the connections for water supply and drainage. Suspended bowls can support up to 400 kg of weight.

What You Need to Know About Installing Wall-Hung Fixtures

Modules for wall-hung fixture installation come with brackets that allow height adjustment and adjustment of the fixing center distance, so they can adapt to all types of fixtures on the market.

The great advantage of carrying out a new installation by building a drywall false wall is that you don't need to dismantle the existing system or carry out demolition to route the new pipes. Even if you change the layout of the fixtures, the pipes can be laid inside the metal framework.

Flush-Mount Module or False Wall Module?

• Flush-mount WC: Complete modules with flush tank have a slim thickness (even just 8 cm) and can be installed flush with a partition wall and covered with a layer of plaster.
• False wall WC: If no demolition is underway or the partition does not allow the module to be recessed, the pre-assembled system can be placed against the masonry and hidden in a thin false wall.
• Adjustments: Prepare the frame for installation by measuring the fixing center distance of the fixture. The brackets can be arranged in an L-shape as spacers from the wall, or used as anchors.

Installing Wall-Hung Fixtures with a Metal Recessed Frame

When installing a wall-hung toilet with a metal frame, start by positioning the frame against the wall. Ensure it is perfectly level both vertically and horizontally. Secure it to the floor and the wall using appropriate screws and plugs, especially if you are working with concrete or brick walls. Connect the water supply and the drainage pipe to the pre-installed connections on the frame. Once the frame is secured and the plumbing is connected, you can cover it with plasterboard, leaving access to the flush plate mechanism. After tiling, install the flush plate and finally hang the toilet bowl onto the two threaded rods, tightening the nuts to secure it.

Wall-Hung Toilet Installation Step-by-Step

• Measure the height from the finished floor to the center of the toilet bowl outlet (usually around 40-42 cm).
• Mark the position of the fixing rods on the wall or frame.
• Drill holes and insert wall plugs if fixing directly to masonry.
• Secure the mounting frame to the floor and wall.
• Connect the water supply and drainage pipes to the frame.
• Cover the frame with plasterboard and tile.
• Install the flush plate.
• Hang the toilet bowl onto the rods and tighten.

Frequently Asked Questions

Can I install a wall-hung toilet myself?

Yes, if you have basic DIY skills and the right tools. The pre-assembled frames simplify the process, but you must be comfortable with plumbing connections and building a false wall if needed. Always check local building codes.

What is the weight capacity of a wall-hung toilet?

Most wall-hung toilets supported by a metal frame can hold up to 400 kg (880 lbs), which is more than enough for regular use.

Do I need a false wall for a wall-hung toilet?

Not necessarily. You can use a flush-mount frame that fits inside an existing partition wall, or a freestanding frame that is boxed in with plasterboard. If you want a shelf, a false wall is a great option.

How do I adjust the height of the toilet?

The mounting brackets on the frame have adjustment slots. You can set the height of the toilet bowl before tiling by moving the brackets up or down within the frame.

What tools do I need for installation?

You will need a spirit level, drill, screwdriver, wrench, tape measure, and possibly a plumbing kit for the water and waste connections.
