How Thick Should the Wall Be for Wall-Hung Toilets?

The wall-mounted toilet has a stylish and elegant design, which is beloved by many consumers. Let's take a look at the relevant knowledge regarding the thickness of the wall for wall-mounted toilets.

一、What is the required wall thickness for wall-mounted toilets

The thickness of the wall for a wall-mounted toilet is about 18-22 centimeters. The thickness may vary depending on the specific product, with a common size being around 12 centimeters. It’s best to consult the manufacturer for exact measurements. The water tank bracket typically involves masonry or a steel frame covered with cement pressure plates for protection, which adds approximately 5 centimeters. The decorative surface is usually finished with tiles or stone, with a thickness of 3-5 centimeters. Therefore, the total thickness of the wall behind the wall-mounted toilet should be between 18-22 centimeters.

二、Considerations for purchasing wall-mounted toilets

1、Reserve a power outlet

Smart toilets require electricity, so it’s important to pre-install an outlet. Choose a suitable position, making sure not to place it directly behind the toilet to avoid installation issues.

2、Regarding pipes

During installation, use iron expansion pipes to fix it in the ground, and it is recommended to secure 2-4 iron expansion pipes on the wall with red bricks for support. For future maintenance, consider placing a stone slab on top of the water tank to provide working space for replacing the water inlet valve if needed.

3、About dimensions

Before purchasing, plan the area for the toilet and choose the right rough-in size. The rough-in size refers to the distance from the center of the toilet drainage outlet to the wall. Common sizes on the market are 305 mm and 400 mm; select according to your home requirements.

4、Load-bearing capacity

Wall-mounted toilets can theoretically support over 400 kg. This is a static value, so if you have individuals over 100 kg, it's advisable to be a bit cautious.

5、Water pressure

Toilets with tanks have lower water pressure requirements, while tankless wall-mounted toilets have specific water pressure needs to ensure effective cleaning. Insufficient pressure may lead to inadequate flushing.
