Shower Renovation Costs in Canada (2026 Guide)

Shower renovation costs in Canada vary widely in 2026 depending on waterproofing, tile complexity, plumbing changes, and whether you stay within the existing footprint.
In 2026, the true cost comes down to waterproofing quality, tile complexity, plumbing scope, and whether you’re staying within the existing footprint.
This guide breaks down realistic shower renovation costs in Canada, what actually drives pricing, and how to budget without cutting corners.

In this guide to shower renovation costs in Canada, we’ll break down realistic price ranges, timelines, and the cost factors that change quotes.

How Much Are Shower Renovation Costs in Canada in 2026?

The biggest mistake homeowners make is comparing a true shower renovation to a “fixture swap.”
Once demolition, proper waterproofing, substrate prep, and tile work are involved, most projects move into five-figure territory—especially for custom walk-in showers.

Shower Renovation Cost Breakdown (Where the Budget Really Goes)

One of the biggest misconceptions about shower renovations is that most of the cost is tile or fixtures.
In reality, the budget is spread across labour, preparation, waterproofing, and technical execution.
Below is a realistic breakdown of the main cost components in a professionally built shower renovation.

• Demolition & disposal: Removal of existing tub/shower, tile, drywall, and debris management.
• Framing & substrate prep: Correcting out-of-plumb walls, reinforcing framing, installing proper backer systems.
• Waterproofing system: Membranes, corners, transitions, drain integration, and detailing.
• Shower base: Prefabricated base or custom tiled pan with correct slope and drainage.
• Tile & setting materials: Tile, thinset, grout, trim pieces, and layout-specific materials.
• Tile installation labour: One of the largest cost drivers, especially for large-format or complex layouts.
• Plumbing work: Valve upgrades, drain relocation, supply changes, and testing.
• Glass & hardware: Semi-frameless or frameless glass, clips, hinges, and handles.
• Finishing & sealing: Silicone, paint touch-ups, accessories, and final detailing.

In most cases, labour and technical execution account for a larger share of the budget than the visible finishes.
That’s also where quality differences between contractors show up the most.

What Actually Drives the Cost of a Shower Renovation

When homeowners compare quotes, the difference usually comes down to waterproofing detail, prep quality, plumbing scope, and tile labour.
That’s why shower renovation costs in Canada can swing significantly depending on what’s behind the walls—not just what you see.

1) Waterproofing system and installation quality

Waterproofing is the foundation of a shower renovation—period. The difference between “looks good” and “lasts 20 years”
is what’s behind the tile: membranes, transitions, corners, penetrations, and how the base is built.
Many high-performing showers are built using integrated waterproofing systems from reputable manufacturers.

• Example waterproofing systems:
  Schluter® Shower System
  and
  wedi® Building Systems.
• More complex showers (niches, benches, multiple corners) require more detailing, time, and precision.
• Cheap waterproofing shortcuts can lead to leaks, mold, and full tear-outs later—never worth it.

2) Tile format and layout complexity

Tile selection affects both materials and labour. Large-format tile can look premium, but it demands near-perfect
wall prep and careful layout. More cuts, patterns, niches, and feature walls increase install time quickly.

• Large-format tiles (e.g., 24″×48″) usually require higher prep standards and tighter layout tolerances.
• Mosaics and small-format tiles can raise labour due to sheet alignment, grout lines, and detailing.
• Natural stone typically adds cost (material, sealing, handling, and often additional substrate considerations).

3) Shower base: prefab vs custom

A prefab base can be efficient and reliable when used correctly. A custom tiled base can be beautiful, but it requires
a correct slope, proper drain integration, and flawless waterproofing at transitions.

• Prefab base: typically faster installation and predictable performance.
• Custom tiled base: higher labour, more detailing, and higher consequence if incorrectly built.

4) Plumbing scope (the silent budget mover)

Staying close to existing plumbing is one of the best ways to control costs.
Moving a drain, changing valve locations, converting from tub to shower, or reworking supply lines can add meaningful cost.

• Keeping the footprint often saves money and reduces permit complexity.
• Drain relocation and valve repositioning typically require more demolition and repair.
• Older homes sometimes reveal surprises once opened (framing issues, water damage, outdated lines).

5) Glass and hardware costs

Frameless glass looks incredible—but it’s not a small add-on. Custom glass, upgraded hardware finishes,
and tighter tolerances can push this line item up quickly.

Prefab Shower Base vs Custom Tiled Base

Prefab vs custom is one of the most common decision points that affects shower renovation costs in Canada.
Both can perform extremely well when installed correctly—the right choice depends on the space, budget, and long-term expectations.

Both options can perform extremely well when installed correctly.
The key is choosing the right system for the space, budget, and long-term expectations.

Common Shower Renovation Scenarios (Real-World Budgeting)

Basic shower refresh (same footprint)

• Limited demolition
• New fixtures and selective tile work
• Minimal plumbing changes

Typical range: $3,500 – $8,500

Tub-to-shower conversion

• Tub removal + disposal
• New shower base + waterproofing
• Tile surround
• Glass and upgraded fixtures

Typical range: $7,500 – $15,000+

Custom tiled walk-in shower

• Full demolition and substrate prep
• Upgraded waterproofing system
• Custom tile layout with niche(s)
• Frameless or semi-frameless glass

Typical range: $12,000 – $25,000+

How Long Do Shower Renovation Costs and Timelines Vary?

Shower renovation timelines depend heavily on scope, drying times, and material lead times.
Below are realistic timelines for common project types when work is done properly—not rushed.

• Basic shower refresh: 3–5 working days
• Tub-to-shower conversion: 5–10 working days
• Custom tiled walk-in shower: 10–15+ working days

Timelines can extend due to:

• Waterproofing and curing requirements
• Custom glass fabrication and installation
• Tile complexity or specialty materials
• Permit inspections (when plumbing changes are involved)
• Unexpected framing or moisture issues discovered during demolition

Rushing a shower renovation almost always leads to long-term issues.
Proper sequencing and dry times are critical for durability.

Situations That Significantly Increase Shower Renovation Costs in Canada

Certain design choices and site conditions consistently push shower renovation costs higher.
Understanding these upfront helps avoid surprise budget jumps later.

• Drain relocation or converting to a linear drain
• Curbless or barrier-free shower designs
• Steam showers or multiple shower heads/body sprays
• Large-format tile (e.g., 24″ × 48″) on uneven walls
• Multiple niches, benches, or integrated shelving
• Natural stone tile requiring sealing and additional prep
• Older homes with out-of-plumb framing or hidden water damage

None of these are “bad” choices—but they require more planning, labour, and technical execution.

Permits: Do You Need One for a Shower Renovation?

Permit requirements depend on scope and municipality. A cosmetic update may not require a permit,
but changes to plumbing, drains, or structural framing often do.

How to Budget Smart (Without Cutting Corners)

• Stay near existing rough-ins: moving drains and valves can add serious cost.
• Choose waterproofing first: tile and fixtures are replaceable—failed waterproofing isn’t.
• Be realistic about tile labour: complex layouts cost more than most people expect.
• Plan for the unknown: once walls open up, older homes can reveal framing or moisture issues.

Common Mistakes That Blow Up Shower Renovation Budgets

• Skipping proper substrate and wall preparation
• Using inadequate waterproofing at corners and penetrations
• Choosing complex tile layouts without accounting for labour
• Finalizing glass selections too late in the process
• Assuming walls and floors are level in older homes
• Not coordinating ventilation upgrades for moisture control

Most cost overruns come from assumptions—not materials.
Clear planning upfront is the most effective way to stay on budget.

FAQ: Shower Renovation Costs in Canada

Can you renovate a shower for under $5,000?

Sometimes—if it’s a limited refresh with minimal demolition, no waterproofing rebuild, and no plumbing changes.
Most true shower renovations that include proper waterproofing and tile work exceed that range.

What’s the most expensive part of a shower renovation?

Labour and technical execution—waterproofing, substrate prep, tile installation, and plumbing changes.
Materials matter, but the skilled work behind the tile is usually the cost driver.

Does a tub-to-shower conversion cost more than a basic shower upgrade?

Yes. A conversion typically involves more demolition, plumbing adjustments, and a full build-back of the shower base and walls.

How much more does a curbless shower typically cost?

Curbless showers often cost more due to added planning, slope/drain requirements, and detail work at transitions.
The exact increase depends on the floor structure, drain location, and waterproofing approach.

Is large-format tile (24″×48″) more expensive to install?

Usually, yes. Large-format tile often requires higher wall prep standards, careful layout, and more precision.
Labour can increase due to substrate correction and handling.

Do I need a permit for a shower renovation in Hamilton?

It depends on scope. If plumbing is moved or modified, a permit is more likely. For the local breakdown, see our Hamilton permit guide linked above.
