How to measure a toilets rough in

So you're looking to replace or upgrade your old toilet, but you're unsure which measurement you should be shopping for? Not to worry, we give you the basics below to ensure you get the right size.

This is simply a case of finding the distance between the wall and the flange, or alternatively the bolts at the base that secure the loo to the floor.

The most common fit these days is 12", which is seen as the standard measurement in the US. However, this isn't always the case. If you have an older home, there is a chance that you could have a 10 or 14 inch model. That's why it's important to do the necessary research in your bathroom to reduce the chances of needing to send your product back.

The reality is, it's quite a simple task. All you're going to need is a measuring tape and a bit of knowledge that I'm about to give you.

1. First things first, place you tape up against the wall behind the loo. Take care to not include the baseboard in this measurement. Keep in mind this should be a finished wall.

2. Now extend the tape to the hold down bolts in the center in a straight line, which is the location of your waste pipe outlet, and note down the size. If you find that you have two bolts on each side, the best practice is to measure to the center of the back bolt.

It's really that simple!

A quick fix to the method above, would be to find the specification sheet of your current installation. But if that's not an option, the guide above will be sufficient. You should note that you are able to get a smaller sized option than what you currently have, but you would have to leave a larger gap at the wall. It's not recommended, but it's an option, especially if you have your heart set on a specific unit that doesn't quite fit yours.
