The shower is the centrepiece of any modern bathroom. Whether you're replacing a tired tub-shower combo, converting a bathtub to a walk-in shower, or building a custom tile shower from scratch, the investment pays off in daily comfort and home value. Shower renovation costs in Ottawa range from $2,500 for a basic pre-fab shower unit to $15,000+ for a custom tile walk-in shower with frameless glass enclosure. The main cost drivers are the enclosure type (pre-fab vs custom tile), glass doors (framed vs frameless), fixtures (standard vs rain head systems), and size. A shower renovation can be a standalone project or part of a full bathroom renovation. Standalone shower upgrades take 3–7 days and cause less disruption than a full bathroom remodel.
Pre-fab acrylic shower unit: $2,500–$5,000 installed. One-piece or multi-piece acrylic units (e.g., MAAX, Kohler, American Standard). Available in standard sizes (32x32, 36x36, 48x36, 60x32). Includes walls, base, and sometimes a built-in seat. Pros: affordable, waterproof by design, fast installation. Cons: limited design options, basic appearance, fixed sizes. Tub-to-shower conversion: $3,000–$8,000. Removes the bathtub and installs a shower in the same space. Options include a pre-fab base with tile walls, full custom tile, or an acrylic unit. Plumbing modifications for relocating the drain cost $500–$1,500. Note: If the home has only one bathtub, keeping it may be important for resale — families with young children prioritize bathtubs. Custom tile shower: $5,000–$12,000 for a standard-sized shower. Includes waterproof membrane (Kerdi or equivalent), mortar bed, tile (walls and floor), fixtures, and glass enclosure. The gold standard for bathroom renovations. Unlimited design options — choose any tile, pattern, niche configuration, and layout. Luxury walk-in shower: $10,000–$20,000+. Features may include large-format porcelain or natural stone tile, frameless glass enclosure, linear drain, rain head with hand shower, body jets, built-in bench, multiple niches, LED lighting, and heated floor. Statement showers in master ensuites. Curbless (zero-entry) shower: Add $1,000–$3,000 to standard shower costs. The entire bathroom floor slopes to the shower drain, eliminating the step-over curb. Requires careful floor preparation and waterproofing of a larger area. Essential for accessibility/aging-in-place renovations. Stunning modern appearance. Steam shower: Add $2,000–$5,000 to custom shower costs. Requires a steam generator ($1,500–$3,000), vapour-sealed enclosure (floor-to-ceiling tile and a sealed glass enclosure), and steam controls. Luxury wellness feature that transforms your shower into a steam room.
Waterproofing: $500–$1,500 depending on method and area. Schluter Kerdi membrane (sheet or liquid applied), Laticrete Hydro Ban, or RedGard are the industry standards. Every custom tile shower MUST have a waterproof membrane behind the tile. This is the most important component — failed waterproofing leads to mould, rot, and structural damage costing $10,000+ to repair. Shower base/pan: Pre-formed base ($200–$800), mortar bed with membrane ($500–$1,200), or curbless floor preparation ($800–$2,000). Pre-formed bases are faster but limit drain location and tile options. Mortar beds allow custom slopes and drain placement. Glass enclosure — framed: $500–$1,500. Aluminum frame with tempered glass. Budget-friendly, many style options, easier to install. Standard for most bathroom renovations. Glass enclosure — semi-frameless: $800–$2,000. Minimal frame hardware, tempered glass panels. A step up in appearance from fully framed. Glass enclosure — frameless: $1,200–$3,500. Heavy-duty tempered glass (3/8 to 1/2 inch thick) with minimal hardware. Premium modern appearance. Showcases the tile work. The preferred choice for custom tile showers. Shower fixtures: Standard single-function valve and head ($200–$500 installed). Thermostatic valve with rain head and hand shower ($500–$1,500). Full multi-function system with body jets ($1,000–$3,000). Brands: Moen, Delta, Kohler (mid-range), Grohe, Hansgrohe (premium). Shower niche: $200–$500 per niche installed. Built-in storage recessed into the shower wall. Standard niche fits between studs (14 inches wide). Horizontal niches spanning the full wall width are trending ($400–$800). Linear drain: $300–$800 installed. Sleek alternative to centre drains. Typically installed along one wall. Required for curbless showers. Available in stainless steel and tile-insert styles.
Size matters: The minimum comfortable shower size is 36x36 inches, but 48x36 or larger is much more comfortable and popular in Ottawa renovations. If space allows, 60x36 or larger creates a luxury experience without breaking the budget. Tile selection: Large-format tiles (12x24, 24x24) on walls create a spacious, modern appearance with fewer grout lines. Use smaller tiles (2x2 mosaics) on the shower floor for better traction and to conform to the slope. Accent tiles in the niche or as a feature stripe add visual interest. Heated floors: Extend heated floor tile into the shower area for maximum comfort. A heated shower floor eliminates the cold-tile shock on Ottawa winter mornings. Schluter Ditra-Heat can be installed in wet areas. Ventilation: Adequate bathroom ventilation prevents moisture damage. A minimum 80 CFM exhaust fan (110+ CFM for showers larger than 36 sq ft) vented to the exterior is essential. Humidity-sensing fans that run automatically after showering are the best option. Accessibility: Even if aging-in-place isn't an immediate concern, consider installing blocking (reinforced backing) in shower walls during renovation. This allows grab bars to be installed later without opening walls. Zero-cost during construction, expensive to add later.
A basic pre-fab walk-in shower costs $2,500–$5,000. A custom tile walk-in shower costs $5,000–$12,000. Luxury walk-in showers with premium finishes cost $10,000–$20,000+.
Converting a bathtub to a walk-in shower costs $3,000–$8,000 including plumbing modifications, new shower base, walls, fixtures, and glass enclosure.
Pre-fab shower installation takes 2–3 days. Custom tile shower construction takes 5–8 days. Luxury showers with complex tile work and multiple features may take 7–12 days.
If your home has only one bathtub, keeping it is recommended for resale value — families prioritize bathtubs. If you have a second bathtub or the bathroom is for adults only, converting to a walk-in shower is a popular and valuable upgrade.
