What is the cost to rebuild a leaking Ottawa shower from the studs out with proper waterproofing?

A complete shower rebuild from the studs out in Ottawa typically costs $8,000 to $18,000, with most homeowners spending $12,000 to $15,000 for a standard 36-inch by 60-inch shower with mid-range finishes. This wide range reflects the dramatic difference between a basic rebuild with standard porcelain tile and a luxury installation with large-format natural stone, multiple niches, and premium fixtures.

The high cost reflects the extensive work required for a proper rebuild. Once you're down to the studs, everything must be rebuilt to current standards: new electrical rough-in for lighting and heated floors ($800 to $1,500), plumbing rough-in including moving the drain if needed ($1,200 to $3,000), insulation and vapour barrier ($300 to $600), cement board or foam backer board substrate ($600 to $1,200), complete waterproofing membrane system ($800 to $1,500), tile installation ($2,000 to $6,000 depending on tile choice), plumbing fixtures and trim ($1,500 to $4,000), and finishing work including caulking and cleanup ($500 to $1,000).

Ottawa's climate makes proper waterproofing absolutely critical in this rebuild. The dramatic humidity swings between our bone-dry winters and humid summers create challenging conditions for any moisture barrier. A quality waterproofing system like Schluter Kerdi or RedGard liquid membrane is non-negotiable — this is your one opportunity to do it right. The waterproofing must extend behind the entire shower area, properly seal all corners and penetrations, and integrate with a waterproof shower pan or linear drain system.

Material choices significantly impact the final cost. Standard 12-inch porcelain tile with basic fixtures keeps costs toward the lower end, while large-format natural stone, custom niches, rainfall showerheads, and heated floors push costs toward the upper range. Many Ottawa homeowners add heated floors during a complete rebuild since the electrical rough-in is already exposed — this adds $1,200 to $2,500 but transforms the shower experience during our long winters.

The silver lining of a complete rebuild is that everything will be new, properly waterproofed, and warrantied. Unlike a patch job that might fail again in a few years, a proper rebuild should last 20 to 30 years with routine maintenance.
