Average Basement Renovation Costs in 2025
In Ontario, a basement renovation typically ranges from $25,000 to $65,000 depending on the size of the basement, finishes, and whether you’re finishing an empty space or remodeling an existing one.
Basic finishing (walls, flooring, lighting): $25,000 – $35,000
Mid-range renovation (rec room, storage, bathroom): $35,000 – $50,000
Luxury or in-law suite (bedrooms, kitchen, full bathroom): $55,000+
Homeowners in Kitchener and Waterloo often aim for rental suites or high-end rec rooms, while Fergus, Elora, and Elmira families commonly focus on functional spaces like offices or playrooms.

Key Factors That Impact Basement Renovation Pricing
Every basement project is different, but several major factors affect the final cost:
Square footage: Larger basements naturally cost more.
Layout changes: Adding bedrooms, bathrooms, or kitchens increases complexity.
Plumbing & electrical: Installing a bathroom or wet bar adds significant costs.
Finishes & materials: Luxury flooring, stone fireplaces, or custom cabinetry increase budgets.
Moisture control: In older Fergus and Elora homes, waterproofing or foundation repair may be needed before finishing.
Basement Renovation Costs in Kitchener & Waterloo
The average Kitchener or Waterloo basement renovation runs $45,000 – $85,000. These larger urban homes often include:
Full rec rooms with built-in entertainment systems
Bedrooms for guests or renters
Modern bathrooms with tiled showers
Rental suites to generate extra income
Because of strong demand for secondary suites, basement renovations in Kitchener and Waterloo often lean toward legal in-law apartments, which require permits, egress windows, and proper ventilation.
Basement Renovations in Fergus, Elora & Elmira
In smaller towns like Fergus, Elora, and Elmira, homeowners often take a more practical approach. The average cost here is closer to $28,000 – $65,000.
Popular upgrades include:
Turning basements into family rooms or home gyms
Adding office space for remote work
Simple guest bedrooms with basic bathrooms
Smart storage solutions for older homes with less space upstairs
While budgets might be lower than in Kitchener/Waterloo, the impact is just as big — these renovations add significant usable living space and property value.

Tips for Budgeting a Basement Renovation
Whether you’re in Waterloo or Elora, careful planning helps avoid surprises:
Plan around must-haves: Decide if you need a bathroom, kitchenette, or just open space.
Set aside 10–15% contingency: Especially important in older homes with unknowns.
Consider ROI: Rental suites in Kitchener/Waterloo can pay themselves off in just a few years.
Hire a local contractor: Regulations differ in Centre Wellington vs. Waterloo Region — having a contractor who understands both is key.
