If your toilet rocks, leaks at the base, or you smell sewer gas near it, the wax ring has failed. This is a simple 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 plenty. Here’s exactly what you need.

Best Overall: Korky 6000BP WaxFree Seal (Bolts Included)Editor’s Choice
Check the Korky 6000BP WaxFree Seal on Amazon →
Korky’s WaxFREE seal does the job of a wax ring without the one-shot problem. With a wax ring, if you set the toilet down slightly off-center, you’ve used up the wax and need a new ring. Korky says its red rubber seal can be repositioned during installation, and that its two-piece foam rings adapt to flanges above, even with, or below the finished floor. It fits 3-inch and 4-inch drain pipes. If the flange sits well below the finished floor, raise it rather than sealing over it.
The kit also brings new mounting hardware: two bolts, two metal and two plastic washers, and two nuts, per Korky. Closet bolts corrode; if yours are rusted or stripped, this saves the second trip to the store. Korky says it is made in the USA and lists a 10-year warranty.
- ✅ Repositionable during installation
- ✅ Adapts to flanges above, even with, or below the floor
- ✅ Bolts and nuts in the kit
- ✅ No wax mess on your hands and floor

Verdict: The forgiving wax-free choice, and the one to buy if the old bolts are rusted.
Best Traditional Wax: Eastman 40145 Jumbo Wax Ring with Flange
Check the Eastman 40145 Jumbo Wax Ring on Amazon →
If you prefer traditional wax (which most plumbers still use), a jumbo ring with a flange is the one to reach for. The Eastman 40145 listing gives it as a 1-1/4-inch-thick wax ring with a built-in flange, sized for 3-inch or 4-inch waste lines, and pitches it for exactly the job where a regular ring does not carry enough wax for a secure seal. Like any wax ring, it compresses once the bowl is set, so you get one attempt.
- ✅ 1-1/4 inches thick — extra wax for a flange sitting below floor level
- ✅ Built-in flange guides the seal onto the drain
- ✅ Time-proven seal method
- ❌ Not repositionable — one shot
Traditional jumbo wax ring, 1-1/4 inch thick · built-in flange · fits 3-inch or 4-inch waste lines
- Traditional wax — the seal type most working plumbers still reach for
- Built-in flange guides the seal onto the drain
- Proven seal for a 3-inch or 4-inch drain
- 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 pick if you are confident setting the bowl in one drop.
Wax-Free Alternative: Fluidmaster 7530P8 Better Than Wax (2-Pack)
We are not linking this one right now. When we checked on September 29, 2026, the single 7530 was out of stock on Amazon and the 7530P8 2-pack was down to a handful of units from a third-party seller. If you find it on a store shelf, it works the same way as the Korky.
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
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
- 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.
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.
If the Flange Is Cracked or the Bolts Pull Loose
A wax ring can only seal against a flange that is sound and bolted down. If the flange has broken at a bolt slot, or the closet bolts lift out of it as you tighten the nuts, a new ring fails the same way the old one did and you are pulling the bowl again.
The Oatey Fix-It Stainless Steel Flange Repair Ring is the part for that: the listing gives stainless steel construction, elongated bolt slots that take 1/4 in. and 5/16 in. T-bolts, and four slotted mounting tabs that sit under a standard toilet base. The listing gives it as repairing a broken or cracked flange rather than replacing it, and as being used together with a traditional wax ring — so it is bought alongside one of the seals above, not instead of them.
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.
Bottom Line
For most DIYers, a wax-free seal is worth it — it’s repositionable, which eliminates the most common installation mistake. The Korky 6000BP is the one we link, and it brings new bolts with it. If you’re comfortable with traditional wax, the Eastman 40145 jumbo ring with flange is the one to buy.
You have to pull the toilet to change a wax ring, which is the one moment when swapping the whole fixture costs you no extra labor. Our toilet picks are worth a look first.
