Toilet Leaking? Find Where, Then Fix It — Cost Guide
Toilet leak repair costs $150–$450 in most cases. Before anything else, triage the water: is it on the floor around the base, beading on the supply line or valve, or dripping from under the tank? The location points to the repair — and to the price.
Cost figures are illustrative budgeting examples, not verified local averages or quotes. Actual pricing depends on inspection, parts, access, and provider fees; confirm it before approving work.

Where is the water coming from?
Every toilet leak starts somewhere, and the source sets the price. If safe, dry the exterior and note where water has appeared and when. Do not flush again to reproduce a known leak; stop using the fixture and describe the observations to the provider.
Base of the toilet — water pooling on the floor
Symptom: water seeps out from under the base after flushing. Likely cause: the seal under the toilet has failed. Price: $200–$450. The repair involves lifting the toilet, replacing the seal, and resetting the fixture — leave this one to a pro.
Supply line or shutoff valve — water beading on the line
Symptom: water beading or dripping on the supply line behind the toilet. Likely cause: a worn connector or corroded valve. Price: $150–$300. A supply-line swap is a safe DIY job: shut off the valve, unscrew the old line, screw on the new one — 15 minutes with an adjustable wrench.
Tank or tank bolts — water dripping from under the tank
Symptom: water dripping from under the tank or dampness where tank meets bowl. Likely cause: worn tank bolts or failed gasket. Price: $175–$350. The tank must be drained and unbolted — call a pro.
Bowl cracks
Symptom: fine crack in the porcelain or unexplained dampness. Price: $350–$900+. Porcelain cannot be reliably repaired — a crack means replacing the toilet.
What to do in the next 10 minutes
- Do not flush again. Every flush pushes more water through the leak.

Frequently Asked Questions
How much does it cost to fix a toilet leaking at the base?
A toilet leaking at the base costs $200–$450 to repair in most cases. A base leak usually means the seal under the toilet has failed, so the repair involves lifting the toilet, replacing the seal, and resetting the fixture.
Can a small toilet leak wait for later?
No. Even a slow leak soaks the floor a little more every day, and the moisture spreads into the flooring and subfloor silently. A $150–$300 fix today can become a $1,000+ floor repair when the leak is ignored for months.
Will a toilet leak damage the floor?
Yes. Repeated moisture softens vinyl and laminate, stains tile grout, and rots the wooden subfloor under the toilet. A soft or spongy floor around the toilet signals damage that goes beyond the leak itself.
What should I do first when the toilet leaks?
Stop using the toilet, then close the supply valve behind the toilet by turning the handle clockwise. Dry the area, note exactly where the water appears — supply line, tank, or base — and call to describe the location of the water.
