What to do if…
the toilet base is wet and you suspect it is leaking into the floor

Short answer

Shut off the water to the toilet (or the home’s main water if you can’t) and start drying right away—then arrange an urgent plumber visit, because water under floors can spread and mold risk increases if drying is delayed.

Do not do these things

  • Don’t keep flushing to “see if it happens again.”
  • Don’t use caulk around the base as a fix; it can trap water and hide an ongoing leak.
  • Don’t ignore nearby electrical risks (outlets, heaters, wiring) or handle plugs while standing on a wet floor.
  • Don’t delay drying—wet building materials left damp can develop mold.
  • Don’t start tearing out flooring in panic; stabilize first and document.

What to do now

  1. Make a safer pause. Keep everyone out of the bathroom, and put towels down to prevent slips.
  2. Shut off the water to the toilet.
    • Find the shutoff valve behind/next to the toilet (on the supply line). Turn it clockwise until it stops.
    • If the valve is stuck or still leaks, go to Step 3.
  3. Shut off the home’s main water supply (if needed).
    • If you can access the main shutoff, turn it off (wheel valves typically turn clockwise; lever/ball valves usually turn a quarter-turn until perpendicular to the pipe).
    • If you’re in a condo/apartment and can’t access it, contact building management.
  4. Stop using the toilet. Put a note on it so nobody flushes by habit. Use a different bathroom if available.
  5. Contain and dry immediately.
    • Mop up standing water, wring towels into a bucket, and keep the area as dry as possible.
    • Increase airflow (bath fan, open window if safe). Use a fan/dehumidifier if you have one.
    • Dry as quickly as possible (24–48 hours is a common guideline). If the water smells foul or looks dirty/discoloured (possible sewage contamination), limit contact and consider professional cleanup guidance.
  6. Check where the water may have traveled.
    • Look at the ceiling below (if any) and nearby baseboards for fresh staining, soft spots, or dripping.
    • If you see sagging drywall, dripping, or rapid spreading, keep that area clear and treat it as urgent.
  7. Call the right help.
    • Renter: notify your landlord/property manager immediately, in writing if possible (“active bathroom leak, water at toilet base, suspected leak into subfloor; water shut off”).
    • Owner: call a licensed plumber for urgent service. If there’s significant wetting into flooring/ceiling, consider a water-damage restoration company for proper drying.
  8. Document, then keep stabilizing. Take photos/video of the wet area and any staining below/around it. Keep receipts for any emergency supplies or services used to prevent further damage.

What can wait

  • You don’t need to diagnose the exact cause right now (wax ring, loose bolts, supply line/valve, tank-to-bowl leak, drain/flange issues).
  • You don’t need to decide on permanent repairs, flooring replacement, or an insurance strategy in the first moments.
  • You don’t need to open walls/floors immediately unless a professional directs you for safety or drying.

Important reassurance

This is a common home emergency. Stopping the water and drying promptly are the most important first moves, and they can prevent the situation from becoming a much bigger repair.

Scope note

This guide covers first steps to limit damage and buy time. A plumber typically needs to confirm the source and fix the toilet seal/connection and assess any subfloor damage.

Important note

This is general information, not professional plumbing, electrical, legal, or insurance advice. If water is near electrical components, if you can’t stop the leak, or if you see ceiling sagging/dripping, get qualified help urgently.
