Community Tips
A toilet wax ring that's too thin or poorly compressed will cause water to leak into the subfloor within weeks, leading to structural rot and mold that costs $2,000+ to remediate—always use a double-thickness wax ring like Korky Wax Ring with Horn ($8-12) when replacing an old toilet to ensure a proper seal.
Before installing a new wax ring, scrape the closet flange completely clean with a putty knife to remove all old wax residue and debris, as even small particles will prevent the ring from creating an airtight seal and will compromise the installation.
Homeowners often underestimate how much force is needed to seat the toilet properly—the wax ring requires firm, even pressure downward (typically 50-100 lbs) to compress fully, and most leaks result from toilets that weren't pressed down hard enough during installation rather than from defective rings. ---
