Is It Worth Fixing?

A toilet replacement costs $150-500. Most common repairs cost $10-50 in parts. If your unit is less than 20-30 years (porcelain), 5-10 years (internal parts) old, repairing it is almost always the better financial decision. Even if you're not comfortable with DIY repairs, a service call ($100-200) plus parts is still cheaper than replacing the entire unit.

When to replace: If the unit is past its expected lifespan, has had multiple failures, or the compressor/motor needs replacing (these are expensive components that signal end-of-life).
