What Drives the Price
Understanding these key factors will help you estimate your costs more accurately and know what to expect when getting quotes.
1. Leak Duration
Shower pan leaks often go unnoticed until ceiling damage appears below.
Example: Recent leak: $2,000. Long-term leak with rot: $6,000.
2. Floor Level
Second-floor showers cause ceiling damage below.
Example: First floor on slab: $2,500. Second floor with ceiling repair: $4,500.
3. Tile Replacement
Matching or replacing shower tile adds significant cost.
Example: New tile installation: $1,500–$3,000.
The Hidden Leak That Costs More the Longer It's Ignored
Shower pan leaks are unusual in water damage work because the damage is almost always worse than it looks from the bathroom side, since the leak has typically been running behind the wall for months before anyone notices.
Why the diagnosis costs money before the repair does
Unlike a burst pipe with an obvious source, a shower pan leak requires a flood test or dye test to confirm the pan itself is failing rather than the grout, caulk, or a supply line nearby. That diagnostic step, often $150 to $400, is money well spent because tearing out a shower to find the leak was actually a loose fitting is a very expensive mistake.
Insist on the diagnostic test before agreeing to full pan replacement. Some contractors skip straight to demolition because it's a bigger job to sell, when a resealed drain assembly or new grout would have solved it for a fraction of the cost.
The subfloor is usually the real bill
Because these leaks go undetected for weeks or months, the subfloor beneath the pan and the ceiling of the room below (on upper-floor bathrooms) have often absorbed water long enough to rot. Replacing a shower pan without checking subfloor integrity is incomplete work; a spongy or discolored subfloor needs to come out even if it adds $500 to $1,500 to the job.
Questions to ask before shower pan demolition
- Was a flood test or dye test performed to confirm the pan is the source?
- Has the subfloor been probed with a moisture meter, not just visually inspected?
- Is the tile salvageable or does the whole surround need to come out?
- For upstairs bathrooms, has the ceiling below been checked for damage?
