The bathroom renovation timeline, step by step: from first visit to first shower

Short answer: a full bathroom renovation usually takes three to seven weeks on site, depending on size and scope, plus planning and ordering time before that. The biggest schedule risk is not construction. It is starting demolition before the tile, vanity and fixtures are on hand.

Homeowners often ask how long they will be without a bathroom. The honest answer depends on decisions made weeks before the crew arrives. Here is the sequence we follow on a typical project, and what happens at each step.

Phase 1: Site visit and scope (week 1)

We visit, measure, check the floor and existing plumbing, look for signs of water damage, and talk about how the bathroom is used. The most important decision here is whether the layout stays the same or changes. Keeping fixtures where they are is faster and less expensive. Moving a toilet or shower means new drains and usually a permit.

Phase 2: Design, selections and estimate (weeks 1 to 3)

You choose tile, vanity, countertop, fixtures, lighting and accessories. We confirm layout details like niche placement, valve heights and outlet locations, and provide a written estimate. Making every selection before work starts is what keeps the build on schedule.

Phase 3: Permits and ordering (weeks 2 to 6)

If the project needs a building permit, drawings are submitted and reviewed by the municipality. At the same time, materials are ordered. Custom vanities, special glass and imported tile can have long lead times. Glass shower doors are usually measured after tile is installed, so they are one item that is ordered during construction.

Phase 4: Protection and demolition (days 1 to 3)

We protect floors and the route through the house, set up dust control, shut off water and remove fixtures, tile and board down to framing. This is when hidden problems appear: rotted subfloor, old leaks, undersized framing or outdated wiring. We show you what we find and price any repairs before moving on.

Phase 5: Repairs and rough-in (days 3 to 10)

• Framing: repair subfloor, add blocking for grab bars and vanities, frame niches and benches.
• Plumbing: move or replace drains, vents and supply lines, set the shower valve and drain.
• Electrical: new circuits, GFCI protection, lighting, heated floor controls and fan wiring.
• Ventilation: install the fan and duct it to the outside.

If a permit is in place, a rough-in inspection happens here, while everything is still visible.

Phase 6: Insulation, board and waterproofing (days 8 to 14)

Exterior walls are insulated and sealed, cement board or foam board goes up in the wet areas, and the waterproofing membrane is installed. The shower pan is flood tested. This phase takes patience because membranes and mortar beds need cure time. It is also the phase that decides whether the bathroom lasts.

Phase 7: Tile (days 12 to 22)

Tile is usually the longest single step. Heated floor mats go down first, then floor tile, walls, niches and trim. Large format tile and intricate patterns take longer than simple layouts. Grout goes in after the setting material has cured, then gets sealed if the product calls for it.

Phase 8: Finishes and fixtures (days 20 to 30)

1. Paint ceiling and walls.
2. Install vanity, countertop and sinks.
3. Set the toilet and connect faucets and shower trim.
4. Install lights, mirror, accessories and hardware.
5. Measure and install the glass shower enclosure, which can take one to three weeks from measurement.

Phase 9: Final inspection and walkthrough

Final inspection is booked where a permit applies. We walk the bathroom with you, test every fixture, the fan and the heated floor, and note anything that needs touching up. You receive warranty information and care instructions for the materials used.

What causes delays

• Selections not finalized before demolition.
• Backordered or damaged materials.
• Hidden water damage that needs structural repair.
• Inspection scheduling, especially in busy seasons.
• Changes to the layout after rough-in.
• Access to remote or water access properties, which adds material transport time.

Timing tips for cottage owners

Fall, winter and early spring are good times to renovate a cottage bathroom, because the building is used less and crews have more availability than in the peak summer season. If the cottage is closed for winter, plan for heat during construction, since tile setting materials and membranes need temperatures above their minimums to cure properly.

If it is your only bathroom, ask about temporary options, or plan the work for a period when you can stay elsewhere. In homes with more than one bathroom, we keep the others usable and contain dust so daily life continues.
