How to Install a Wall-Hung Toilet: Step-by-Step Guide 2026

Wall-hung toilets are a popular choice for modern bathrooms, offering a sleek, minimalist look and making floor cleaning much easier. With the fixtures fixed to the wall and raised off the ground, cleaning operations are simpler and the toilets have softer, more elegant shapes. For an even more seamless wall-hung toilet, there is a system that eliminates side fixings. In this guide, we'll walk you through the installation process, including a clever new mounting system that keeps the toilet looking truly suspended.

Why Choose a Wall-Hung Toilet?

Wall-hung toilets offer several advantages over traditional floor-mounted models:

• Easier cleaning: With no base touching the floor, you can mop or sweep underneath effortlessly.
• Modern aesthetics: The floating design creates a clean, contemporary look.
• Space-saving: Ideal for small bathrooms, as the tank is hidden inside the wall.
• Adjustable height: You can install the toilet at a height that suits your needs.

Understanding the Mounting System

Modern wall-hung toilets use a metal frame (often called a carrier or support frame) that is installed inside the wall or against it. This frame includes the flush tank, waste pipe connections, and horizontal bars onto which the toilet bowl is attached. The new SupraFix 2.0 system takes this a step further by eliminating visible side fixings, so the toilet appears to float without any brackets showing.

Key Components of the SupraFix 2.0 System

• Two support brackets with horizontal holes for the wall bars and vertical threaded bushings for securing the bowl from above.
• Special bolts that fit through the same holes used for the toilet seat, allowing you to fix the bowl without side access.
• A soundproofing kit with pre-cut insulation to reduce noise.

Step-by-Step Installation of a Wall-Hung Toilet

Step 1: Prepare the Wall Frame

Ensure the support frame is securely fixed to the wall and floor, and that all plumbing connections (water supply and waste) are in place. The frame should be level and at the desired height.

Step 2: Attach the Support Brackets

Take the two support brackets from the SupraFix 2.0 kit. Each bracket has a horizontal hole that slides onto the rear bar of the frame. Keep the flat side facing upward, then click the brackets onto the bar. They are designed to snap into place without error.

Step 3: Slide the Toilet Bowl into Position

With the brackets attached, slide the toilet bowl onto the bars and push it gently against the wall. Use a spirit level to check that the bowl is perfectly horizontal. Adjust as needed.

Step 4: Tighten the Fixing Nuts

Screw the nuts onto the bars to stabilize the bowl, but do not overtighten. The goal is to hold the bowl firmly without cracking the porcelain.

Step 5: Secure the Bowl from Above

Now, use the special bolts provided with the SupraFix system. These bolts go through the same holes that will later hold the toilet seat. Insert them into the vertical threaded bushings of the brackets and tighten gently. This secures the bowl without any side fixings visible.

Step 6: Install the Toilet Seat and Cover

Attach the toilet seat using the provided hardware. The SupraFix kit includes a soft-close mechanism for the seat. Make sure the seat is aligned and functions smoothly.

Step 7: Soundproofing (Optional)

If your kit includes a soundproofing sheet, it will be pre-cut so you can remove the central part to fit around the bowl. This helps reduce noise from flushing.

Step 8: Final Checks

Connect the water supply, turn on the valve, and check for leaks. Flush a few times to ensure everything works correctly. Finally, caulk around the base of the bowl for a clean finish.
