What to do if toilet flange is flush with floor?

The toilet flange needs to be on top of the finished floor. Meaning the bottom edge of the flange needs to be on the same plane as the toilet. So if your toilet sits on the tile, the flange needs to be on top of the tile too.

How do I choose a toilet wax ring?

To determine the correct width for your wax ring, simply turn your toilet bowl on its side, and measure the opening on the bottom of your toilet, called the “elbow neck.” Whatever width this measurement is, use that width wax ring. E.g. if the elbow neck measures 3 inches, use a 3-inch wax ring.

When should you use an extra thick wax ring?

If your flange is floor level or slightly below then you can use an extra-thick wax ring. If the flange is lower than a 1/4” below the floor level then you should use a flange extension to raise the flange height or remove and replace the old floor flange and set it to the right height.

What is a standard size wax ring?

Should the toilet flange be flush with floor?

In a typical toilet installation, the floor flange that sits inside the drain opening below the toilet should be flush with the finished floor, or no more than 1/4 inch above or below the floor. When your toilet flange is too high, your toilet may leak water and rock back and forth when used.

Should the toilet flange be even with the floor?

Optimum flange height to aim for is 1/4 inch above the finished floor. This typically allows for almost any type of wax ring to be used and still ensure a good seal. If you recently tiled or changed the bathroom flooring, the flange height is likely less than optimal.

Should you put the wax ring on the toilet or the flange?

Place the wax ring on the closet flange, not on the toilet. Then, pick up the toilet and set it evenly over the closet flange, making sure the bolts come through the bolt holes in the toilet base. Fine-tune the toilet position, so it’s right where you want it, then push it straight down so it smashes the wax evenly.
