Can You Install a 400mm Toilet on a 450mm Distance？

Renovation is a very cautious matter. If the renovation is not done well, various issues can easily arise during use later on. For example, if the toilet's drain distance is 450mm, can I choose a toilet with a 400mm distance?

Can I choose a 400mm toilet if the drain distance is 450mm：

Yes, you can. After installation, the distance between the back of the toilet and the wall will be about 3cm. Choosing a toilet with a 300mm or 400mm drain distance is quite common. In practice, the distance from the center line of the toilet outlet to the wall should be 320mm or 420mm, and a 10mm error is considered normal as long as it can be installed properly.

Tips for toilet installation：

1、Check the drainage pipes and floor level

Before installing the toilet, conduct a thorough check to ensure that the drainage pipes are free from dirt, sand, paper, or other foreign materials. Also, ensure that the floor where the toilet will be installed is level. If the floor is uneven, it may need to be removed.

2、Determine the center of the drainage pipe

Flip the toilet over to determine the center of the toilet drain and draw an intersecting centerline. This line should extend to the base of the toilet.

3、Toilet maintenance

Align the toilet's crosshair with the drainage hole in the floor, install the toilet level, compress the sealing ring, and then install the floor screws and decorative caps.

4、Ensure good floor sealing

Install a dedicated sealing ring at the toilet drain or apply a ring of silicone sealant or cement mortar; the ratio for this mixture is approximately 1:3.

5、Install the tank components

Flush the inlet pipe for 3-5 minutes to check the cleanliness of the water supply line. Install the angle valve and connecting hose, and connect the hose to the fitted inlet valve of the water tank and secure the water source.

6、Debugging and checking

Check if the seals of the water supply and shut-off valve are functioning properly, ensure that the installation position of the drainage valve is flexible and free from blockages or leaks, and check for leaks in the inlet valve's filter device.
