Where the water at the base is really coming from
A toilet that leaks at the base is usually leaking from the seal underneath it, the wax ring, or from a loose bolt that lets the bowl rock. But water on the floor near a toilet is not always from the base, so check three other sources first. A sweating tank, a weeping supply line and a drip from the tank bolts all end up in the same puddle.
Sit down next to the toilet with a dry paper towel and a flashlight. Wipe the floor, the base, the supply line and the underside of the tank. Then flush once and watch which spot gets wet first.
| What you see | Likely cause | Can you wait? |
|---|---|---|
| Water only after a flush, seeping from under the bowl | Failed wax ring or bad flange seal | Not long. It soaks the subfloor |
| Toilet rocks or shifts when you sit | Loose closet bolts or a broken flange | Stop using it until it is fixed |
| Wet on the supply line or shutoff valve | Worn supply line or valve packing | Close the valve and call |
| Beads of water on the outside of the tank | Condensation from cold water in humid air | Yes, it is not a leak |
| Drips under the tank where it meets the bowl | Tank-to-bowl gasket or tank bolts | A few days, with a towel and a bucket |
| Hairline crack or weeping from the porcelain | Cracked bowl or trapway | No. Replace the toilet |
Why the wax ring fails
The wax ring is a thick gasket that sits between the bottom of the toilet and the closet flange, the ring bolted to the floor over the drain. It keeps water and sewer gas inside the pipe each time you flush. When it stops sealing, a little water works its way out around the base.
Rings fail for a few ordinary reasons. The toilet may have been set a bit crooked, the bolts may have loosened over time, or the flange may sit lower than the finished floor after new tile went in. A rocking toilet breaks the seal a little more with every flush.
Sewer gas smell near the toilet is a second clue. If the bathroom smells like drains even when the bowl is full of water, the seal is probably open.
What to do before anyone arrives
Stop the leak safely
Treat a base leak as dirty water. It comes from the drain side, so keep kids and pets away and wear gloves when you wipe it up.
- Turn the shutoff valve behind the toilet clockwise until it stops.
- Flush once to empty the tank, then sponge the rest out of the bowl.
- Lay towels around the base and photograph the wet area for later.
- Do not run caulk around the base to hide the leak. It traps water under the toilet and rots the floor.
- Keep the toilet out of use until it is dry and sealed.
Repair options and honest trade-offs
The standard fix is to shut off the water, drain the toilet, lift it off, scrape away the old wax and set a new ring. Then we check the flange, replace the closet bolts and set the toilet level on the new seal. That takes a plumber one visit when the flange is sound.
A reseat with a new ring works when
- The flange is solid and sits at the right height
- The floor around it is dry and firm
- The bowl and tank have no cracks
- Bolts and the toilet itself are in good shape
You need more than a ring when
- The flange is cracked, rusted or below floor level
- The subfloor feels soft or has dark stains
- The porcelain is cracked
- The toilet is old and parts are worn out
A damaged flange can often be repaired with a repair ring or a flange extender, so the whole floor does not have to come up. Soft flooring is a different job. If the subfloor has gone spongy, it has to be cut out and replaced, and we will tell you that before the work starts.
What a slow base leak does if you wait
A small leak looks harmless, but the water has nowhere to go except into the floor. Over months it can stain the ceiling below, lift vinyl and tile edges and feed mold in the subfloor. Florida humidity speeds all of that up.
If your toilet sits on a concrete slab, the damage tends to show up as lifted flooring and a musty smell. On a second floor, look for stains on the ceiling beneath the bathroom. Either way, a leak that appears only after flushing is the easiest kind to miss.
We cover this repair under toilet repair, and if the bowl itself is the problem, we can talk through replacement. A sewer smell that spreads past the bathroom can also point to a venting or drain problem, which is a job for drain cleaning.
Royal Palm Beach note: a leak and your water bill
Palm Beach County Water Utilities supplies water and sewer to most of the Village, and its customer service number is (561) 740-4600. Addresses south of Southern Blvd are instead served by Village of Wellington Utilities, (561) 791-4010. If a base leak ran for a while, call the right utility and ask how they handle a bill that jumped after a repair.
We do not set utility policy, so we cannot say whether any adjustment is available. Keep the repair invoice and your photos handy when you call.

When the leak is a bigger plumbing problem
If every toilet in the house gurgles or the floor drain bubbles when you flush, the water at the base may be a symptom of a slow drain downstream. A backed-up line pushes water up and out wherever the seal is weakest. That needs a drain check, not a new ring.
Neighbors in Wellington and The Acreage call us about the same issue. The first step is the same everywhere: find out whether the leak comes from the seal or from a line that will not drain.
Sources and standards
Toilet installation and flange work follow the Florida Building Code, Plumbing, 8th Edition (2023), the standard inspectors apply, and the Village of Royal Palm Beach says most work needs a permit, so ask before a full replacement. Palm Beach County Water Utilities provides the sewer service.
Leaking toilet base questions in Royal Palm Beach
Can I fix a leaking toilet base with caulk?
No. Caulk around the outside of the base does not stop a bad seal, it only hides it. Water then collects under the toilet and soaks the floor where you cannot see it.
How long does a wax ring last?
There is no fixed lifespan. A ring on a well-set toilet can last for many years, while one on a rocking toilet can fail much sooner. If the toilet moves at all, plan on replacing the ring.
Is the water from my toilet base sewage?
If it appears after a flush, treat it as drain water. Wear gloves, clean the floor with a disinfectant and keep the toilet closed off until it is repaired.
Why does my toilet rock a little?
A loose toilet usually means loose closet bolts, a worn flange or an uneven floor. Rocking breaks the wax seal, so snugging the bolts alone rarely holds for long. Do not overtighten them, because porcelain cracks.
Will a water bill from a Royal Palm Beach leak change after repair?
A seal leak that only runs during flushes seldom adds much to the bill. A running tank is a bigger water user, and a plumber can check the flapper and fill valve at the same visit. For billing questions, call your utility directly.
Do you handle toilet leaks at night in Royal Palm Beach?
Our 24/7 line takes the call day or night, and we send a licensed, insured plumber with same-day appointments when available. Shut the valve behind the toilet first so the floor stays dry while you wait.
