How Long Does a Bathroom Renovation Really Take in Calgary?

Monday, November 24, 2025

The dream of a renovated bathroom—that spa-like retreat with heated floors and a frameless glass shower—is what drives many homeowners. Yet, the question that causes the most anxiety is, “How long will I be without a functioning bathroom?”

The popular answer you hear in casual conversation is often a misleading two to three weeks. The professional, code-compliant, quality-guaranteed timeline for a full, mid-to-high-end bathroom renovation in Calgary, however, is a methodical, multi-stage process that typically spans 4 to 8 weeks of active construction, excluding all the necessary pre-planning time.

This extended timeline isn’t the result of slow contractors; it’s a non-negotiable requirement dictated by science (curing times), safety (inspections), and supply logistics (lead times). For a Calgary homeowner, understanding and respecting this process is the single best way to ensure the project stays on budget and delivers the expected quality and longevity.

Here is the comprehensive, phase-by-phase breakdown of what genuinely drives the duration of your Calgary bathroom renovation.

I. Phase 1: Planning, Design, and Procurement (The Hidden Weeks: 6–16 Weeks)

This phase occurs entirely outside of the construction zone, yet it accounts for the majority of the project’s overall duration. A professional contractor will insist that demolition does not begin until Phase 1 is 100% complete.

A. Design and Layout Finalization (3–6 Weeks)

The process begins with translating your vision into an executable plan.

• Initial Consultation and Budget Setting: Defining the scope (e.g., standard three-piece versus master ensuite with custom walk-in) and setting the financial boundaries.
• Space Planning: If you are moving walls, changing the orientation of the shower, or shifting the toilet, detailed drawings are required. This stage ensures the new layout is functional and complies with minimum clearance requirements under the Alberta Building Code.
• Aesthetic Finalization: This period is spent selecting every single visible item: vanity style, countertop material, mirror size, lighting scheme, paint colour, and every piece of plumbing trim. Indecision here creates exponential delays later.

B. Procurement: The Non-Negotiable Lead Time (6–12 Weeks)

The supply chain is the single greatest bottleneck in any modern renovation. High-end, custom, or specialty items often have long lead times coming into the Calgary market.

• The Custom Factor: Custom vanities, specialized lighting fixtures, or non-stock tiling (especially imported European or large-format tile) can take 6 to 12 weeks to arrive, clear customs, and reach the job site.
• The Contractor’s Inventory Rule: The most critical project management rule is this: All permanent materials (vanity, tub/pan, toilet, all tile, and rough-in plumbing/electrical items) must be physically on-site and inspected for damage or defects before demolition begins. Waiting even one day for a missing faucet trim kit during the finish phase can halt three trades simultaneously and add a week to the schedule.

C. Securing Permits and Scheduling (1–4 Weeks)

For safety and legal compliance, certain projects require a City of Calgary permit, which mandates inspections.

• Permit Necessity: If your renovation involves moving the drain line for a toilet or shower, altering the ventilation system, or making structural changes, a permit is mandatory.
• The Permit Wait: A reputable contractor handles all permit submissions. While the City of Calgary strives for quick turnarounds, the initial permit approval, and the subsequent scheduling of rough-in inspections, must be managed efficiently. A professional contractor schedules the necessary plumbing, electrical, and building inspections to line up precisely with the active work schedule.

II. Phase 2: Demolition and Rough-In (The Dirty & Exposed Weeks: 1.5–2.5 Weeks)

This is the most physically demanding stage, where the bathroom is stripped back to the studs and the new mechanical systems are installed.

A. Demolition, Disposal, and Discovery (2–4 Days)

• Tear-Out: Safe removal of all existing fixtures, drywall, and flooring. This generates significant waste, requiring proper bin placement and disposal, which is managed by the contractor.
• The Contingency Factor: In older Calgary homes (pre-1990s), demolition often reveals hidden issues: previous water damage, poorly sloped drain lines, or outdated wiring. Discovering dry rot, mold, or structural deficiencies behind the walls is common. Remediation—which includes removal, treating the wood, and replacing sections of framing—is often unscheduled work that can easily add 2–5 days of unplanned labour. A professional timeline always factors in a buffer for this “discovery.”

B. Rough-In of Plumbing and Electrical (3–5 Days)

The skilled trades update the hidden infrastructure.

• Plumbing Rough-In: New PEX or copper water lines are run, and ABS drain lines are installed for the new shower, vanity, and toilet locations. Shower valves are installed and pressure-tested.
• Electrical Rough-In: New circuits are run for the ventilation fan (which must be vented outside the home, per code), new lighting (vanity, pot lights, shower light), and new GFI outlets near water sources.
• The Inspection Hold: Once the rough-in is complete, the contractor stops work and calls for the mandatory City of Calgary Rough-In Inspections (Plumbing, Electrical, and often Building). No insulation or drywall can be installed until the Safety Codes Officers have signed off on the work. While the City aims to offer inspection appointments within 1–3 business days, coordinating three different trades for simultaneous sign-off can result in 2–5 days of non-working time waiting for city approval.

III. Phase 3: Structural, Substrate, and Waterproofing (The Critical Curing Weeks: 7–12 Days)

This phase establishes the structural and waterproof integrity of the space. Rushing this section compromises the entire renovation and voids warranties.

A. Framing and Drywall Installation (3–5 Days)

• Framing: Constructing any new walls, installing shower niches, building the shower bench, or prepping the walls for a custom floating vanity.
• Wall Enclosure: Installing vapour barrier (where required) and then hanging moisture-resistant drywall on the walls and specialized cement board in the wet areas (shower/tub surround).

B. Waterproofing and Heated Floors (4–7 Days)

This is the most important step for longevity.

• Shower Pan/Curb: Building and sloping the shower pan base (if installing a custom tiled shower) and ensuring the curb is properly built.
• Membrane Application: Applying the seamless, continuous waterproofing membrane system (e.g., Schluter Kerdi or RedGard). These products are chemicals and require strict curing times. The initial application must dry fully (often 24 hours in dry Calgary air) before the final coat or flood test can be performed. Rushing this step risks catastrophic failure and mold growth behind the tile years later.
• Heated Floors: Laying the radiant heating mat or cable system and encasing it in a self-levelling underlayment. This compound provides a smooth, level base for the tile but requires another 24–48 hours to dry completely before it can bear weight or accept the thin-set mortar.

IV. Phase 4: Finishes and Detailing (The Aesthetic Weeks: 10–15 Days)

This is the phase where precision tiling and final coating take centre stage.

A. Tiling and Grouting (5–10 Days, Highly Variable)

The duration of this step relies entirely on the complexity of the tile:

• Size and Pattern: Simple, large-format tiles installed in a linear pattern are faster. Complex patterns like herringbone, chevron, or intricate mosaics require more cuts, more labour, and more time for proper layout.
• Substrate Check: A professional tiler spends time ensuring the walls are perfectly plumb and square before setting the first tile—a critical step that prevents uneven grout lines.
• The Grout Wait: Once the tile thin-set mortar is cured (typically 24 hours), the grout is applied. The grout then requires a minimum of 48–72 hours to fully cure and dry before it can be sealed and exposed to water.

B. Cabinetry, Trim, and Paint (3–5 Days)

• Vanity and Countertop: Installing the vanity and the heavy quartz or stone countertop (if not part of the vanity unit). Setting the sink and applying silicone sealants.
• Painting: Applying primer and two coats of a high-quality, moisture-resistant bathroom paint to the walls and ceiling, allowing for mandatory drying time between coats.
• Trim and Millwork: Installing baseboards and door casings, followed by final paint touch-ups.

V. Phase 5: Final Fixtures and Handover (The Last Hurdle: 3–4 Weeks)

The final week of work is interrupted by the necessary lead time for the custom glass enclosure.

A. Final Plumbing and Electrical Trim (2–3 Days)

• Plumbing Trim: The plumber returns to install the final faucet, shower trim, diverters, and the toilet.
• Electrical Trim: The electrician returns to install the light fixtures, GFI plate covers, and the mirror.

B. The Custom Glass Delay (2–3 Week Wait)

This is the single most significant scheduling point that requires homeowner patience and understanding.

• Measurement Timing: The glass company cannot take final, accurate measurements for the custom frameless shower door until after the entire tiling process (walls, curb, niche) is 100% complete and cured. This ensures the glass is cut to fit the exact final, potentially imperfect, angles of your tiled walls.
• Fabrication Lead Time: The glass panels must then be cut, the holes for the hinges and handles drilled, and the glass tempered for safety. In the Calgary market, this custom fabrication process typically requires 10 to 15 business days (2–3 full weeks).
• Installation: Once the glass arrives, installation is quick (2–4 hours). The contractor then applies the final silicone seals, which require 24 hours to cure before the shower can be used.

C. Final Punch List and Clean Up (1 Day)

The final step involves the contractor doing a full walkthrough with the homeowner, addressing any minor paint touch-ups or small adjustments, and performing a thorough, professional cleaning before the keys to the new space are handed over.
