Tile Shower Pan Repair Cost Calculator

A grout or caulk-only repair can cost $150-$400 and be done in a few hours. Replacing individual cracked tiles runs $300-$800 depending on tile cost and matching difficulty. A full pan replacement - tearing out all tile, removing the old liner or mortar bed, and installing a new waterproof system - jumps to $2,000-$5,000 once labor, materials, and drying time are factored in.

A prefab fiberglass or acrylic pan is the least expensive replacement option ($200-$600 for materials) but requires removing all surrounding tile to swap out. A tile-over-liner system uses a PVC or CPE liner with a mortar bed and is the most common approach for custom tile work ($400-$900 in materials). A custom mortar bed with a hot-mop or sheet membrane is the premium option and typically costs $600-$1,500 in materials alone before tile.

A professional flood test or electronic leak detection runs $150-$300. If water has been seeping under the pan, the subfloor sheathing - and sometimes framing - may be rotted and need replacement. Subfloor repairs add $200-$800, and any structural framing work adds another $500-$1,500 depending on extent. Never skip a flood test before closing up a repaired shower pan.

Replacing a few cracked tiles is simple when the tile is still in production. If the tile is discontinued, sourcing a close match or ordering a custom-cut tile can add $50-$300. In worst cases, the homeowner must retile the entire shower floor to avoid a visible patch - effectively doubling the scope. Always ask if the original tile is still available before committing to a partial repair.

The waterproof liner or membrane is the most critical element of any shower pan. A PVC or CPE liner that has been punctured, cracked, or separated at a seam cannot be patched reliably - it must be replaced. Liner replacement requires removing all the tile and mortar bed above it. Labor for liner replacement alone runs $300-$600; add materials and re-tiling and the total rises quickly.
