Bathroom renovations in Canada have shifted noticeably over the past five years. The standard tub-shower combo that dominated homes built between the 1970s and 2000s is increasingly being replaced — or at minimum supplemented — by walk-in shower enclosures with tiled surrounds and better ventilation. This article looks at the major design and fixture decisions that come up most often in Canadian bathroom renovations, including how each performs in the humidity and cold conditions common to this climate.
Walk-in Showers
Walk-in showers have become the default choice for primary bathroom renovations in Canada. The appeal is practical as much as aesthetic: a properly waterproofed tiled shower surround (using a membrane system like Schluter KERDI or Wedi rather than traditional cement board) is more moisture-resistant than a fibreglass tub surround, which is prone to cracking at the caulk joints over time.
The key construction detail in Canadian climates is the waterproofing membrane. Exterior walls adjacent to showers require additional attention — thermal bridging through concrete or hollow-core concrete block foundations can lower wall surface temperatures enough to cause condensation inside the shower enclosure. A continuous membrane on all shower surfaces, with properly lapped corners and transitions at the floor, is the standard approach.
For shower size, 90cm × 90cm (36" × 36") is the functional minimum; 100cm × 90cm is more comfortable. Barrier-free or low-profile shower pans (using a prefabricated shower base or a custom mortar bed with a linear drain) are increasingly common in Canadian renovations, both for accessibility and for the cleaner visual line they create.
Glass Enclosures vs. Open Wet Rooms
Frameless glass enclosures (panels of 3/8-inch or 1/2-inch tempered glass with minimal hardware) are the current standard in mid-range and higher-end Canadian bathroom renovations. They're easier to clean than framed enclosures with metal tracks that collect soap scum and mildew. The hardware — hinges, brackets, and handles — needs to be specified in stainless steel or a PVD-coated finish to resist bathroom humidity; polished chrome in humid environments will pit over time.
Open wet room designs (no enclosure, shower area defined by placement and drainage) are common in European renovation design and appear in Canadian urban condominiums. They require a larger tiled floor area and a very precisely sloped floor to drain correctly. The ventilation requirement is also higher, since the entire bathroom floor gets wet.
Heated Tile Floors
In-floor heating in bathrooms is one of the more straightforward upgrades available in a Canadian renovation context. Electric mat systems (a resistance wire embedded in a fibreglass mat that sits below the tile and above the subfloor) are the most common residential application. They're appropriate for bathroom footprints from roughly 4 sq ft up to a full primary bathroom.
The practical considerations:
- A dedicated 15-amp or 20-amp electrical circuit is required — check with your electrician whether the existing panel can support it.
- The mat requires a thermostat with a floor sensor for both comfort and system longevity — running the system without a floor sensor risks overheating and mat failure.
- The additional tile bed height (mat plus thinset) is typically 6–8mm — a consideration at thresholds to adjacent rooms.
- Installation cost in Canada typically runs $12–$25 per square foot for a standard mat system, not including the tile installation.
Hydronic (water-based) radiant systems are more efficient over larger areas but are not practical to add to a single bathroom in a home without an existing hydronic heating system. For most Canadian bathroom renovations, electric mat systems are the reasonable choice.
Freestanding Tubs
Freestanding tubs remain a popular choice in primary bathroom renovations, though their practicality depends significantly on the available floor area and plumbing location. A standard freestanding tub requires a floor footprint of roughly 150–180cm × 75cm, plus clearance on all accessible sides. Floor-mounted faucet risers (sometimes called tub fillers) or wall-mounted faucets add both cost and plumbing complexity — the supply lines need to be rough-in'd at the right location before tile and flooring are installed, since there's no wall to bring them through after the fact.
Cast iron freestanding tubs retain heat the longest — the thermal mass of the iron keeps the water warm for 30–40 minutes longer than acrylic. The trade-off is weight: cast iron tubs can weigh 200–300 kg empty, which is a real structural consideration on upper floors of wood-frame homes. Most Canadian homes from the past 40 years can support this weight, but it's worth confirming with a contractor or structural engineer before purchase.
Acrylic freestanding tubs are the majority of what's sold in Canada today. They're lighter, less expensive, and available in a wide range of profiles. The quality range is significant — look for tubs with a fibreglass-reinforced shell and a minimum 8–10mm acrylic thickness for durability. Thin-shell acrylic tubs flex noticeably under weight and can creak or crack over time.
Vanity and Storage
The move toward larger vanities with double sinks reflects the practical needs of primary bathrooms used by two people. The standard single vanity width in older Canadian homes (60cm–75cm) is being replaced by 120cm–180cm double-sink configurations. Floating wall-mount vanities are increasingly common — they simplify floor cleaning and make the bathroom feel more open.
Storage integration is a consistent challenge in Canadian bathrooms, which tend to be smaller than American equivalents in comparable home sizes. Recessed medicine cabinets, built-in niches in shower surrounds (tiled niches rather than plastic inserts), and toe-kick drawers below the vanity are common solutions that add storage without consuming floor space.
Ventilation
Bathroom ventilation is often the least glamorous part of a renovation and one of the most consequential. Canadian code requires mechanical ventilation in bathrooms without an operable window. Even in bathrooms with windows, a properly sized exhaust fan is the only reliable way to manage humidity from showers in winter, when windows typically remain closed.
The minimum fan rating for a standard bathroom (up to 100 sq ft) is 50 CFM under the National Building Code of Canada requirements. In practice, a 110 CFM or 130 CFM fan is better in a shower-heavy primary bathroom. The duct run from fan to exterior needs to be kept as short and straight as possible — every elbow adds resistance and reduces effective CFM. All exterior penetrations require a dampered vent cap to prevent backdraft in Canadian winters.
Combination fan/light/heat units are popular in Canadian bathrooms as a way to address the cold morning floor temperature before heated floors or full heating systems catch up. These work reasonably well in smaller bathrooms but draw significant power — a 1,500W bathroom heater element on a 15-amp circuit limits what else can be on that circuit.
Material Palette
The visual direction in Canadian bathroom renovations currently favours large-format tile (24×24 or 24×48 on floors and walls), matte or honed stone textures rather than high-gloss, and a limited material palette — typically two materials maximum (tile plus one accent). Warm neutrals (greige, warm whites, soft terracotta) have replaced the cool grey-dominant palettes of the 2015–2020 period. Brushed nickel and matte black hardware remain common; unlacquered brass has appeared in higher-end renovations as the current premium choice.
