Minor wood rot around a toilet flange doesn’t always mean you have to replace the subfloor. Solve the problem with a metal flange support instead.
By the DIY experts of The Family Handyman Magazine:February 2001
If you discover minor rot around the toilet flange, install a closet flange support under the flange to transfer the weight of the toilet to solid wood.
If only the area directly below the flange is rotted, you can install a two-piece steel closet flange support. It goes under the flange and transfers the load of the flange and
toilet (and you) out onto more solid surrounding wood. But if your floor is severely rotted, say more than an inch beyond the flange, you're stuck replacing the flooring around the toilet.
Flange supports are available at home centers and plumbing supply stores for either cast iron, plastic or brass flanges.
Have the necessary tools for this DIY project lined up before you start—you’ll save time and frustration.
Avoid last-minute shopping trips by having all your materials ready ahead of time. Here's a list.
