Average Renovation Costs for a Bathroom: Budgeting Guide

Bathroom renovation costs can vary depending on the size of the space, the age of the home, the quality of materials, and how much of the layout needs to change. A simple cosmetic update will usually cost much less than a full remodel that includes new plumbing, waterproofing, tile, lighting, flooring, and custom finishes.

This article helps homeowners understand the average renovation costs for a bathroom, what affects the final budget, and how to plan a remodel that feels practical, beautiful, and long-lasting.

What Is the Average Bathroom Remodel Cost?

In the current Canadian market, there is no one fixed cost because every bathroom is different. Depending on the scope, the average bathroom renovation cost is 10,000-25,000. 

Small Bathroom Refresh ($5,000 – $10,000)

This focuses on “surface” updates: painting, a new stock vanity, updated mirrors, lighting, faucets, and hardware.

• Best for: Homeowners who want a cleaner look without changing the layout or ripping out tile.

Mid-Range Bathroom Renovation ($15,000 – $25,000)

This includes a new vanity, toilet, flooring, tile, and a standard tub or shower update with minor plumbing adjustments.

• Best for: A noticeable transformation with improved function and modern style.

Full Bathroom Remodel ($30,000 – $50,000+)

Includes full demolition, new plumbing/electrical, high-end waterproofing (like Schluter systems), custom showers, heated floors, and premium finishes.

• Best for: Older Toronto homes with outdated plumbing or those wanting a luxury “spa” experience.

Main Factors That Affect Bathroom Renovation Costs

Here are the main factors that have an impact on bathroom renovation costs:

1. Size of the Bathroom

A powder room costs less than an ensuite because it has fewer fixtures and less square footage for tile and flooring.

2. Scope of Work

A “gut renovation” (stripping to the studs) is significantly more expensive than a “pull and replace” (swapping fixtures in existing spots).

3. Plumbing Changes

Moving a toilet or drain can add $2,000–$5,000 to your budget. Keeping the original layout is the most effective way to save.

4. Tile Selection and Installation

Labour for tile installation often costs more than the tile itself. Detailed patterns (like herringbone) or natural stone require more time and skill.

5. Hidden Issues

In Toronto’s older housing stock, it is common to find mould, rotted subfloors, or outdated galvanized piping once the walls come down.

Bathroom Renovation Cost Breakdown by Project Type

Where Your Bathroom Renovation Budget Usually Goes

• Labour and Project Management (30-40%): Includes demolition, installation, and trade coordination.
• Plumbing & Electrical (15-20%): Essential for safety and code compliance.
• Fixtures & Materials (20-25%): The vanity, toilet, tub, and faucets.
• Tile & Flooring (10-15%): Material and high-precision labour.
• Waterproofing & Prep (5-10%): The most critical “invisible” cost.

How to Set a Realistic Bathroom Renovation Budget

• Decide What Must Change: List non-negotiables like leaking showers or lack of storage.
• Choose Where to Save and Where to Spend: Save on mirrors and hardware; spend on waterproofing and skilled labour.
• Keep the Layout: Moving the “wet wall” is the fastest way to double your plumbing bill.
• Add a Contingency: Always add a 10-15% contingency. Hidden water damage, mould, or aging plumbing are common surprises once demo begins. 

Affordable Bathroom Remodel Ideas That Still Look Great

• Replace the Vanity: A stylish pre-fabricated vanity can change the whole room for under $1,500.
• Update Hardware: Matte black or brushed gold faucets and handles provide an instant modern feel.
• Strategic Feature Tile: Use expensive tile only on one focal wall or in a shower niche.
• Layered Lighting: Adding LED pot lights and sconces makes a small space feel premium.

Do You Need A Permit In Toronto?

Working without required permits risks fines, forced inspections, or complications when selling. A licensed contractor is responsible for managing permit applications as part of the project process.

FAQs

What is the most expensive part of a bathroom renovation?

Labour and tile work. Because bathrooms are small, the precision required for tiling and plumbing in tight spaces drives up the hourly cost.

Do I need a permit for a bathroom renovation in Toronto?

If you are moving plumbing fixtures, changing the footprint, or updating structural elements, a permit is generally required by the City of Toronto.

How long does a bathroom renovation usually take?

A standard full remodel typically takes 3 to 4 weeks. Complex ensuites with custom glass and stone can take 5+ weeks.

Is it cheaper to replace a tub or convert it into a shower?

Replacing a tub with a similar unit is usually cheaper. Converting to a walk-in shower requires new waterproofing, a different drain size, and custom glass, which increases the cost.
