If your toilet rocks, leaks at the base, or you smell sewer gas near it, the wax ring has failed. This is a $10–$15 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.
| Product | Best For | Price |
|---|---|---|
| Fluidmaster 7513 Better Than Wax Ring | Best Overall (No Wax) | ~$15 |
| Korky 6000BP Universal Wax Ring | Best Traditional Wax | ~$8 |
| Fluidmaster 7530P8 Extra Thick Wax Ring | Best for Elevated Floors | ~$10 |
Best Overall: Fluidmaster 7513 Better Than Wax Ring
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.
- ✅ Repositionable during installation
- ✅ Works on any flange height
- ✅ No wax mess on your hands and floor
- ✅ Flexible seal handles rocking toilets better
- ❌ Costs a few dollars more than wax
Best Traditional Wax: Korky 6000BP Universal Wax Ring
If you prefer traditional wax (which most plumbers still use), the Korky Universal is the standard. It includes both a horn (the extended funnel that fits into the drain pipe) and a flat version — you choose based on your flange depth. The polyethylene horn won’t compress like foam, creating a permanent seal.
- ✅ Polyethylene horn — won’t compress over time
- ✅ Universal fit with included horn
- ✅ Under $10
- ✅ Time-proven seal method
- ❌ Not repositionable — one shot
Best for Elevated Floors: Fluidmaster 7530P8 Extra Thick Wax Ring
When a toilet flange sits below the finished floor level (common after tile installation), a standard wax ring won’t bridge the gap. The extra-thick double wax ring is two rings stacked — it fills the additional height. If your flange is more than 1/4″ below the floor surface, this is what you need.
- ✅ Double-thickness for recessed flanges
- ✅ Handles flanges up to 1″ below floor
- ✅ Same Fluidmaster quality
- ❌ Overkill if your flange is at floor level
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.
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, the Fluidmaster Better Than Wax ring is worth the extra $5 — it’s repositionable, which eliminates the most common installation mistake. If you’re comfortable with traditional wax, the Korky Universal is the professional standard at a great price.
