The short answer
Shut off Water and Drain
Locate the shutoff valve behind the toilet, usually near the wall on the supply line. Turn it clockwise until it stops. Then flush the toilet and hold the handle to let as much water as possible drain from the tank and bowl.
Place towels around the base to catch any remaining water. This step keeps the work area dry and prevents slips. If you live in Rogers, write down the shutoff valve location and keep it visible for future emergencies.
Tighten the Base Bolts
Check the two bolts or nuts at the base of the toilet, often hidden under plastic caps. Use a wrench to tighten them gently, alternating side to side. Over-tightening can crack the porcelain, so apply even, light pressure.
If the toilet rocks, the bolts may not be the issue. A rocking toilet often means the floor or the wax ring underneath has shifted. Tightening only masks the problem, so inspect further before assuming it's fixed.
- Use a socket wrench or adjustable wrench
- Lift plastic caps with a flathead screwdriver
- Tighten a quarter turn at a time
- Check for cracks in the porcelain
- Stop if you feel resistance
- Wipe away any water after each adjustment
Replace the Wax Ring
The wax ring, or toilet bowl gasket, sits between the toilet and the floor flange. Over time, it can harden, crack, or shift, causing leaks at the base. Replacing it requires lifting the toilet off the flange.
To do this, disconnect the supply line and unscrew the base bolts fully. Lift the toilet straight up, remove the old ring, and clean the flange. Place a new ring, set the toilet back down, and re-tighten the bolts evenly.
Inspect the Flange and Floor
If the leak continues after replacing the ring, the flange or the subfloor may be damaged. Water can rot the wood under the toilet, causing the flange to sit unevenly. This is not a simple fix and often requires cutting out the damaged area.
A damaged flange or floor can also lead to bigger issues like structural weakening. Water damage pros handle this kind of repair, as it involves careful removal and replacement. Do not attempt to patch a rotted floor without proper assessment.
- Look for soft or discolored wood around the base
- Check if the toilet rocks side to side
- Smell for musty odors indicating hidden moisture
- Inspect the flange for cracks or rust
- Feel for dampness on the floor nearby
Know When to Call the Pros
If you cannot stop the leak after tightening bolts and replacing the ring, the problem may be deeper. A cracked flange or rotted subfloor needs professional tools and experience. Attempting a temporary fix can allow water to seep into walls or ceilings.
Water damage pros can assess the extent of the leak, dry out affected areas, and repair the floor properly. They also check for hidden moisture that could lead to mold. Acting quickly reduces the risk of long-term damage to your home.
Water damage does not wait
Water keeps spreading into floors and walls, so it is worth acting early. Calls are answered 24/7.

Why does my toilet leak at the base after flushing?
A leak after flushing often means the wax ring is worn or the bolts are loose. Water pressure during a flush can push water through gaps. Check the bolts first, then inspect the ring for cracks or hardening.
Can I use caulk to stop a base leak?
Caulk is not a fix for a leak at the base. It may hide the water temporarily, but the leak will continue underneath. The proper fix is to replace the wax ring or tighten the bolts, not to seal the outside.
How do I know if the floor is damaged?
Press on the floor around the toilet. If it feels soft or spongy, water has likely soaked into the wood. Also check for discoloration or a musty smell. These signs mean the subfloor may need professional repair.
