What is the cost to fix a leaking shower pan in a Vancouver condo before renovating?

Fixing a leaking shower pan in a Vancouver condo typically costs between $3,500 and $8,000, and it almost always requires a complete tear-out and rebuild of the shower floor and lower walls — there is no reliable way to patch a failed shower pan from above. This is one of the most common and most urgent bathroom issues in Metro Vancouver condos, and the cost can escalate dramatically if water has damaged the subfloor, neighbouring units, or common property.

The reason repairs are expensive is that a shower pan leak means the waterproofing membrane beneath the tile has failed. Water has been seeping through the grout and tile, past the compromised membrane, and into the subfloor structure. In a condo, that water often travels through the concrete slab or plywood subfloor into the unit below — causing ceiling stains, mould growth, and damage that the leaking unit's owner may be liable for under the strata corporation's bylaws.

The repair process involves several steps. First, the existing tile, mortar bed, and failed waterproofing membrane on the shower floor and lower 12–18 inches of the shower walls must be completely removed. This demolition typically costs $500–$1,200 including disposal. Next, the subfloor must be inspected for water damage and rot — in older Vancouver condos with plywood subfloors, water-damaged sections may need replacement ($300–$800). The shower drain and drain connection should be inspected and replaced if corroded ($200–$500 for parts and labour by a licensed plumber).

A new waterproofing system is then installed — either a Schluter Kerdi membrane system or a liquid-applied membrane like RedGard or Laticrete Hydroban. The membrane must cover the entire shower floor, wrap up all walls to a minimum height of 6 inches above the finished shower floor (preferably the full height of the shower enclosure), and integrate with the drain using a bonding flange or compression ring. This waterproofing work costs $1,500–$3,000 depending on the shower size and system used. New tile is then installed over the membrane ($1,500–$3,500 for a standard shower).

In a condo, the strata implications add complexity and cost. You must notify your strata council immediately upon discovering a shower pan leak — most strata bylaws require prompt disclosure of water infiltration affecting common property or other units. Your strata corporation's insurance may cover some of the damage to common property and affected units, but your own unit's repair costs typically fall on you. Many strata corporations now require an engineer's moisture assessment ($500–$1,000) before approving shower pan repairs, particularly if water has reached neighbouring units.

Strata approval for the repair work itself is generally expedited for active leaks, but you will still need to provide your contractor's proof of insurance (minimum $2 million liability is standard across Metro Vancouver strata corporations) and WorkSafeBC clearance letter. Work hours are typically restricted to 8:30 AM–4:30 PM weekdays, which extends the project timeline.

If you are planning a full bathroom renovation anyway, the shower pan repair cost is essentially absorbed into the renovation budget — you would be tearing out the shower regardless. However, if the leak has caused damage to the subfloor, structural framing, or neighbouring units, those additional remediation costs apply on top of your renovation budget. Mould remediation behind shower walls in a Vancouver condo — where the high ambient humidity accelerates mould growth — typically costs $1,000–$3,000 depending on the extent of contamination.

The total cost breakdown for a shower pan repair in a Metro Vancouver condo:

• Demolition and disposal: $500–$1,200
• Subfloor repair (if needed): $300–$800
• Plumbing inspection and drain work: $200–$500
• New waterproofing membrane system: $1,500–$3,000
• New tile installation: $1,500–$3,500
• Strata-required engineering assessment (if applicable): $500–$1,000
• Mould remediation (if present): $1,000–$3,000

The most important takeaway is this: do not delay a shower pan repair. Every day a shower pan leaks in a Vancouver condo, water is accumulating in the subfloor and potentially affecting the unit below. In Vancouver's humid climate, mould can establish in wall cavities within two to three weeks of sustained moisture exposure. What starts as a $3,500 repair can quickly become a $10,000–$15,000 problem if water damage spreads to structural elements and neighbouring units.
