Standard Clearance Dimensions Around Toilets: What You Need to Know

When installing a toilet, it’s essential to consider the overall size of the bathroom space to determine the installation location. Additionally, a certain amount of space should be reserved around the toilet. What are these dimensions?

Dimensions to be Reserved Around the Toilet

A distance of 45 to 50 centimeters should be left in front of the toilet to allow for passage and comfort when sitting down. On the sides, a space of about 70 to 90 centimeters is recommended to ensure enough room for movement, making it easier to reach for toilet paper or other items. As for the back of the toilet, the space required depends on the toilet's rough-in dimension, which can be 30, 35, or 40 centimeters. This measurement is taken from the center of the waste pipe to the wall.

How to Properly Install a Toilet

1、There are various types of toilets, so it’s important to conduct a thorough inspection before installation. First, ensure that the drain pipe is free of any debris and not clogged. The floor where the toilet will be installed must be level and clean, without any stains.

2、Next, turn the toilet upside down to find the center of the waste pipe and draw a center line. Extend this center line to outline the installation position for the bottom screws. Use a hammer drill to make holes in the floor for the anchors, and pre-install expansion screws and plastic anchors.

3、Proper sealing is crucial, so apply silicone sealant around the pipe. If using cement mortar, ensure a 1:3 ratio. Secure the toilet and make sure the crosshair aligns with the center of the waste pipe, then press firmly on the sealing gasket.

4、Finally, apply additional silicone sealant at the bottom. Avoid using the toilet until the sealant has fully cured. Once it’s completely cured, install the angle valve and the water inlet valve, and connect the water supply. Check to ensure that the flushing works smoothly.

In summary：the above outlines the necessary space to be reserved around the toilet during installation and emphasizes the importance of having adequate room. If the bathroom is small, opting for a compact toilet may be a suitable alternative.
