If your toilet rocks, leaks at the base, or you smell sewer gas near it, the wax ring has failed. This is an inexpensive part that takes about 30 minutes to replace — but most homeowners don’t know which wax ring to buy or how to do it. I’ve replaced hundreds. Here’s exactly what you need.

The Fluidmaster “Better Than Wax” ring uses a flexible rubber seal instead of traditional wax. The advantage: it’s reusable and repositionable. With a traditional wax ring, if you set the toilet down slightly off-center, you’ve used up the wax — you need a new ring. The rubber seal can be repositioned during installation, which makes this significantly easier for DIYers. It also works on any flange height — though if the flange is actually below the finished floor, raise it rather than sealing over it.
- ✅ Repositionable during installation
- ✅ Works on any flange height
- ✅ No wax mess on your hands and floor
- ✅ Flexible seal handles rocking toilets better
- ❌ Costs more than plain wax
Flexible rubber gasket · reusable and repositionable · no wax mess
- Rubber seal repositions if the toilet shifts while you set it
- No wax to smear, ruin, or get on your hands
- Fits standard 3-inch and 4-inch flanges
- Costs more than a plain wax ring
- Some old-school plumbers still trust traditional wax
- Flange still has to sit at the right height to seal
Verdict: The modern, forgiving choice — especially if you have never set a toilet before.
Best Traditional Wax: Fluidmaster 7513 Extra Thick Wax Ring
Check the Fluidmaster 7513 Extra Thick Wax price on Amazon →
If you prefer traditional wax (which most plumbers still use), the Fluidmaster 7513 is the one to reach for. It ships as a single extra-thick gasket with the polyethylene flange horn already attached — the extended funnel that guides waste into the drain pipe — and Fluidmaster puts 40% more wax in it than a standard seal. The polyethylene horn won’t compress like foam, creating a permanent seal.
- ✅ Extra-thick — also bridges a flange sitting below floor level
- ✅ Built-in flange horn guides the seal
- ✅ Time-proven seal method
- ❌ Not repositionable — one shot
Traditional extra-thick wax ring · includes the horn · fits 3-inch and 4-inch drains
- The standard wax most working plumbers still reach for
- Built-in horn guides waste cleanly into the pipe
- Cheap, proven, and available everywhere
- Single-use — set it wrong and you start over with a new ring
- Messy to handle and position
- Compresses permanently once the bowl is down
Verdict: The dependable, low-cost pick if you are confident setting the bowl in one drop.
Best Wax-Free Kit (Bolts Included): Korky 6000BP WaxFree Seal
Check the Korky 6000BP WaxFree Seal price on Amazon →
The Korky WaxFree seal does the same job as the Fluidmaster rubber ring with one practical extra: the bag includes fresh mounting hardware. Closet bolts corrode; if yours are rusted or stripped, buying the seal and bolts separately is exactly the second trip this kit exists to prevent. It is made in the USA and fits standard flanges.
- ✅ Wax-free — no mess, nothing to smear
- ✅ New mounting hardware in the bag
- ✅ Made in the USA
- ❌ Costs more than a plain wax ring
Wax-free seal · mounting hardware included · universal fit
- No wax to smear or ruin during placement
- Fresh bolts mean you are not reusing corroded hardware
- One bag covers the whole reset job
- Pricier than plain wax
- Overkill if your existing bolts are fine
- Wax loyalists will not be converted
Verdict: Use this when you are replacing the bolts anyway — it is the tidy all-in-one kit.
How to Replace a Toilet Wax Ring
- Shut off the supply valve and flush to empty the tank. Sponge out remaining water from both tank and bowl.
- Disconnect the supply line. Remove the nuts from the floor bolts.
- Rock the toilet gently to break the wax seal, then lift straight up and set aside on old towels.
- Scrape all old wax off the flange and toilet horn with a putty knife. Inspect the flange — if it’s cracked, repair or replace it before continuing.
- Install new closet bolts in the flange slots. Press the new wax ring onto the toilet horn (wax side facing away from toilet).
- Lower the toilet straight down onto the flange, aligning the horn with the drain and the bolt holes with the bolts. Press down firmly and evenly — do not rock.
- Hand-tighten the nuts, then snug down with a wrench. Alternate sides. Do not overtighten — you’ll crack the porcelain base.
- Reconnect supply, turn water on, flush several times and check for leaks.
Plumber’s tip: Flange condition determines seal quality. If the flange is cracked, corroded, or below the floor level, fix that before installing a new wax ring or the seal will fail again. If the bowl will not line up over the drain at all, the flange itself has to move, which is what an offset toilet flange is for.
FAQ
Do I need a wax ring with or without a horn?
Use a ring with a horn (the extended plastic funnel) when the toilet flange is at or below floor level. Use a ringwithout a horn when the flange sits above the floor (rare in new construction). When in doubt, use the horn version.
How do I know if my wax ring is leaking?
Signs include: water pooling at the base of the toilet after flushing, sewer odor in the bathroom, soft or discolored flooring around the toilet base, or the toilet rocking.
Can I reuse a wax ring?
No. Once compressed, wax rings cannot be reused. Always install a new ring when removing a toilet for any reason.
