Is converting a tub to a wet-room expensive in Toronto?

Converting a tub to a wet-room in Toronto typically ranges from $8,000-$25,000+, with most homeowners spending $12,000-$18,000 for a quality conversion. This is significantly more expensive than a standard tub-to-shower conversion due to the extensive waterproofing and structural modifications required.

What Makes Wet-Rooms Expensive

The high cost stems from the comprehensive waterproofing system required. Unlike traditional showers with a curb and door, wet-rooms need the entire floor to be waterproofed and sloped toward a central or linear drain. This involves removing the existing tub, potentially lowering the subfloor, installing a waterproof membrane system, and creating proper drainage slopes. In Toronto's older homes, this often means dealing with concrete subfloors or joists that weren't designed for this type of drainage.

The waterproofing alone costs $3,000-$6,000 and is absolutely critical - any failure can cause expensive water damage to floors below. Professional installation of systems like Schluter-Kerdi or similar membrane systems is essential, especially given Toronto's strict building codes and the potential for insurance issues if water damage occurs from improper installation.

Toronto-Specific Considerations

In Toronto's century homes and older properties, wet-room conversions often require additional structural work. Many older bathrooms have concrete subfloors or limited joist depth, making proper drainage slopes challenging. You may need to lower the floor or raise the bathroom threshold, which can affect transitions to hallways and create accessibility issues.

Building permits are required for wet-room conversions in Toronto, as they involve plumbing and structural changes. The City of Toronto Building Division typically takes 2-3 weeks to approve bathroom renovation permits. The work must meet Ontario Building Code requirements for waterproofing and accessibility, and inspections are mandatory.

Cost Breakdown for Toronto Market

Basic wet-room conversion: $8,000-$12,000 (builder-grade finishes, simple layout)
Mid-range conversion: $12,000-$18,000 (quality tiles, linear drain, good fixtures)
High-end conversion: $18,000-$25,000+ (premium materials, custom features, complex drainage)

These prices include demolition, waterproofing, new plumbing, tiling, and basic electrical. Add $2,000-$4,000 if structural modifications are needed for proper drainage slopes.

Professional Guidance Essential

This is definitely not a DIY project. Improper waterproofing can cause tens of thousands in water damage, and insurance may not cover damage from unpermitted or improperly installed wet-rooms. Licensed plumbers must handle the drain installation and rough-in work, while experienced tile contractors should handle the waterproofing membrane installation.

Next Steps

Get quotes from contractors experienced specifically with wet-room installations - this isn't typical bathroom renovation work. Ensure they're familiar with current Ontario Building Code waterproofing requirements and can provide references for similar conversions. Budget an extra 15-20% for potential structural surprises common in Toronto's older housing stock.
