What Holds The Toilet Flange To The Floor?

Do You Have To Replace The Flange When Replacing A Toilet?
If you notice a lot of water pooling at the base of your toilet and inspect it, you'll discover that your flange is cracked or broken, and you'll need to replace it. Make sure to properly measure your drain pipe and drain to ensure you get the right size replacement flange kit.
Is It Necessary To Caulk Around The Toilet Flange?
Caulk keeps a fouling area at bay. There is no way to clean up mop water, bathtub water, or a less pleasant "bathroom liquid" that gets underneath the toilet. This can be avoided by caulking around the base of the toilet.
Does A Toilet Flange Need To Be Screwed To The Floor?
Closet or toilet flanges must be 1/4" higher than the finished floor. This is done to ensure that the wax ring properly seals to the toilet's flange and hub. If a proper seal is not achieved, leaking will occur. If the flange is lower than or flush with the floor, foam rings are made to cover the gap for a proper seal.
How Much Does It Cost To Have A Toilet Flange Replace?
All of the supplies you'll need to replace your toilet flange and wax ring yourself should cost less than $40. Your total installation cost will be closer to $75 if you use a cast iron flange rather than a PVC flange. A plumber will typically charge around $175 to replace your flange.
