Measuring Your Existing Toilet's Rough-In Distance Made Easy

Before replacing an old toilet with a new one, it's essential to measure the toilet rough-in distance accurately. If you already have a toilet installed, here’s how to measure the rough-in distance.

一、How to Measure the Rough-In Distance with an Existing Toilet

If you already have a toilet in your home, the method for measuring the rough-in distance may vary depending on the floor your unit is located on. Specifically：

1、If your home is not on the top floor, go to the bathroom of the unit directly above yours. Measure the distance from the center of the toilet drain pipe to the wall. This measurement will give you the rough-in distance. If there is a ceiling or drop ceiling in the bathroom, you may need to remove part of it to obtain an accurate measurement.

2、If your home is on the top floor, you should measure the distance from the center of the toilet drain pipe to the wall in the unit directly below yours. This measurement will also indicate the rough-in distance.

Note：If you are unsure how to measure, it’s best to hire a professional to help. This will ensure that the measurement is accurate. The most common rough-in distances for toilets on the market are typically 35 cm and 40 cm. Be meticulous in your measurements to avoid installation issues.

二、Important Considerations When Replacing a Toilet

1、Before replacing the toilet, check to see if the floor is level and prepare a new toilet that matches the measured rough-in distance. You should also inspect the toilet drain pipe for any blockages; if there are any, clean the pipe thoroughly.

2、Additionally, check the toilet tank for any leaks and inspect the water pipes in your home for any leaks as well. If there are leaks, address them promptly. Only proceed with the replacement once everything is deemed to be in proper working order.
