The Bathroom Renovation Challenge
Bathrooms are the most expensive rooms per square foot to renovate because every surface must be waterproof, every connection is plumbing, and the margin for error is low. A poorly executed bathroom renovation does not just look bad — it causes moisture damage, mould, and structural issues that can cost far more to fix than the original renovation.
Done right, a bathroom renovation delivers the best ROI of any room in the house. In Vancouver's competitive real estate market, a dated primary bathroom or a single-bathroom house without an ensuite can meaningfully impact resale value.
Waterproofing: The Foundation of Every Bathroom
Before you think about tile patterns or vanity styles, understand that waterproofing is the most important technical aspect of any bathroom renovation. In Vancouver's wet climate, this is particularly critical.
Shower and Tub Surround Waterproofing
The area around showers and tub surrounds must be waterproofed behind the tile. This is not optional — water migrates through grout and tile joints, and without a proper membrane behind the tile, water will eventually reach the framing.
Methods we use:
Sheet membrane systems (Schluter Kerdi, RedGard): Applied directly to substrate before tile. Kerdi is a polyethylene fleece membrane bonded to cement board or drywall. Excellent performance and widely used by quality tile contractors.
Liquid-applied membranes (RedGard, AquaDefense): Rolled or painted on in multiple coats, sealed at corners with fabric tape. Fast to apply, effective when applied correctly.
Schluter Shower System: A complete system that integrates waterproofing, tile substrate, and drain in a unified approach. Our preferred system for most custom shower builds.
Shower Pan Waterproofing
The shower floor is the highest risk area for water damage. Options:
Mud-set shower pan with CPE liner: Traditional method, durable when done correctly, allows for custom slopes and drain placement.
Tile-ready foam shower pans: Pre-sloped foam bases (Wedi, Schluter Kerdi, USG Durock) that are lightweight, pre-waterproofed, and accept tile directly. Fast installation, excellent performance.
Prefab shower bases: Acrylic or fibreglass pans in standard sizes. Faster installation, not custom, suitable for budget-focused renovations.
Bathroom Ventilation
Inadequate ventilation is Vancouver's most common cause of bathroom mould. Code requires a properly sized exhaust fan ducted to the exterior (not into the attic or soffit). Fan sizing is measured in CFM (cubic feet per minute) — minimum 50 CFM for bathrooms under 100 square feet, higher for larger spaces.
We recommend Energy Star certified fans with humidity sensors — they automatically run when moisture is detected and turn off when humidity normalizes. This eliminates the human factor of forgetting to run the fan.
Critical: The exhaust duct must terminate outside the building. Bathroom fans venting into attics are a code violation and a leading cause of attic mould in Metro Vancouver.
Tile: Making the Right Choice
Tile selection is where most homeowners feel overwhelmed. Here is a framework for making confident choices.
Floor Tile Considerations
Slip resistance: Floor tiles must meet slip resistance requirements (especially in wet areas). Look for tiles with a Dynamic Coefficient of Friction (DCOF) of 0.42 or higher, or tiles specifically rated for wet use. Textured, matte, or small-format tiles with more grout lines provide better traction than large, polished tiles.
Size relative to space: Large-format tiles (24x24 or bigger) can look stunning in large bathrooms and have the advantage of fewer grout lines. In small bathrooms, they can feel disconnected from the space. Medium format (12x12 to 18x24) works well in most Vancouver bathroom sizes.
Porcelain vs. ceramic: Porcelain is denser, harder, and more water-resistant than ceramic. For bathroom floors and shower walls, use porcelain (rated for the specific application). Ceramic works fine for non-wet areas.
Wall Tile
Shower walls have more flexibility in format because they are vertical — slip resistance is not required. This opens the door to more decorative options:
- Large-format slabs (24x48 or larger): Minimal grout lines, sophisticated appearance, requires very flat substrate
- Subway tile: Classic, versatile, timeless
- Mosaic (1x1 to 4x4): More grout lines (higher maintenance), allows complex patterns, works well as accents
- Handmade/artisan tile: Beautiful variation in texture and colour, higher cost, distinct character
Grout
Grout colour and type are as important as tile selection:
Epoxy grout: Near-impervious to staining, does not require sealing. More expensive and less forgiving to install. Best for kitchen backsplashes and high-stain areas.
Unsanded cement grout: For joints under 1/8 inch. Used for most wall tiles in showers.
Sanded cement grout: For joints 1/8 inch and larger. Used for most floor tile applications.
Colour selection: Grout that matches or closely coordinates with tile creates a more seamless appearance. High-contrast grout (white tile, dark grey grout) creates graphic interest but shows variation and requires more cleaning.
Fixtures and Fittings
Showers
Walk-in shower vs. shower/tub combo: In primary bathrooms, the trend in Vancouver is strongly toward large walk-in showers. Freestanding soaker tubs are aspirational but statistically underused. If you have a second bathroom where a tub is practical (for children or resale), keep a tub there; convert the primary to a walk-in shower.
Glass enclosures: Frameless glass (10mm glass) is the premium standard — cleaner appearance, easier to clean, longer lifespan than framed enclosures. Expect to pay $1,500 to $3,500 for a quality frameless glass door and panel for a typical shower.
Shower valves: Specify a thermostatic valve for consistent temperature control. The luxury standard is separate thermostatic and volume controls, allowing you to set temperature once and never adjust. Brands like Grohe, Hansgrohe, and Kohler offer good quality in various price ranges.
Shower head options: A basic fixed head, a handheld, or both via a combination system. For walk-in showers, a rain head (ceiling-mounted or overhead on an arm) combined with a handheld is very popular.
Bathtubs
If you are including a bathtub in the renovation:
Freestanding soaker tubs: High visual impact, requires a dedicated floor drain and floor-mounted faucet. Deep soak models (typically 55-65cm deep) provide genuine soaking depth. Cast iron is heavy but retains heat; acrylic/composite is lighter but can feel less substantial.
Drop-in tubs: Set into a tile deck, integrated into cabinetry. More space-efficient than freestanding, allows storage in the deck surround.
Undermount tubs with deck: Same concept as drop-in but the tub rim is below the tile deck level for a cleaner appearance.
Vanities and Sinks
Floating vanities: Wall-mounted, no floor contact. Easy to clean under, visually opens up the floor space, feels contemporary. Requires solid blocking in the wall framing for attachment — this is done during rough framing, not something that can be easily added after walls are closed.
Undermount sinks: Set below the counter surface. Easier to clean (no rim to trap debris). The standard choice for custom vanities with stone countertops.
Vessel sinks: Sit above the counter surface. Bold visual statement. Requires counter height adjustment for proper ergonomic use (counter is lower since the basin is raised). Not practical for every household.
Double vanity: Worth serious consideration for ensuite bathrooms used by two people. Even in moderately sized ensuites (60 to 80 square feet), a 60-inch double vanity is often achievable and dramatically improves morning routines.
Heated Floors: The One Luxury Worth It
Electric in-floor heating (radiant mat systems) in bathrooms is consistently rated by homeowners as one of the most satisfying renovations they made. The cost to add during tile installation is modest — typically $800 to $1,500 for a standard bathroom — but incredibly difficult and disruptive to add later.
In Vancouver's cool winters and shoulder seasons, stepping onto a warm bathroom floor is genuinely pleasant. The operating cost is minimal given the small area and typical usage (set the thermostat to warm an hour before your usual wake time).
We include in-floor heating as a standard recommendation for bathroom tile work.
Permits for Vancouver Bathroom Renovations
Most cosmetic bathroom renovations (new tile, fixtures, vanity) do not require permits. A building permit IS required when:
- Plumbing drain or vent locations change
- A new bathroom is added to the home
- Structural walls are modified
- Adding a new bathroom exhaust (if electrical work requires panel changes)
For permit-free work, an electrical permit may still be needed for adding circuits, GFCI upgrades, or new exhaust fan wiring.

The Design Phase: Getting It Right Before You Build
The most expensive changes in bathroom renovation happen after construction starts. A design investment before breaking ground is always worthwhile:
- Measured drawings: Accurate as-built drawings of the existing space
- New layout: Layout for all fixtures, showing clearances and traffic flow
- Elevation drawings: Wall-by-wall tile layouts to calculate quantities and identify any challenges
- 3D visualization: Helpful for understanding how the finished space will feel
Many tile suppliers and designers offer free or low-cost design services as part of material purchases.
We work through a design phase with every bathroom client before finalizing pricing, which produces more accurate quotes and fewer surprises.
