A basement is one of the most underrated spaces in a home. Many people use it only for storage, but with the right renovation, it can become a cozy living area, a home office, a gym, or even an entertainment room. But before starting, one of the first questions homeowners ask is: how much does it cost to renovate a basement?
The truth is, the cost can vary widely depending on size, design, and the type of finish you want. Let’s break down the factors that affect basement renovation costs, give you some price ranges, and help you understand how to plan your budget.
Average Basement Renovation Cost
In Australia, a basement renovation typically ranges between $25,000 and $70,000 or more. The final price depends on your goals. For example:
- Basic makeover (painting walls, flooring, lighting): $15,000 – $25,000
- Mid-range renovation (adding insulation, plumbing, electrical, bathroom): $30,000 – $50,000
- High-end remodel (custom finishes, home theatre, luxury bathroom, wet bar): $60,000+
Every project is unique, and Hunter Wide Building and Construction works with homeowners to design renovations that fit their lifestyle and budget.
Factors That Influence Basement Renovation Costs
1. Size of the Basement
The bigger the basement, the higher the cost. A large open basement requires more materials, flooring, paint, and lighting.
2. Purpose of the Space
- A home office may only need drywall, paint, and proper lighting.
- A guest suite requires plumbing, insulation, and a bathroom renovation.
- An entertainment area could involve soundproofing, a bar, and media installation.
The function of the basement has the greatest impact on the total cost.
3. Plumbing and Electrical Work
If your design includes a kitchenette, bathroom renovation, or laundry area, plumbing and electrical updates will add to the budget. High-quality wiring and waterproofing are essential for basements because they are prone to moisture.
4. Waterproofing and Insulation
Basements can get damp, especially in older homes. Waterproofing and proper insulation are non-negotiable steps to protect your investment.
5. Flooring Choices
- Vinyl or laminate: budget-friendly and moisture-resistant.
- Tile: durable and stylish but more expensive.
- Carpet: cozy but requires special moisture protection.
6. Custom Features
Custom-built shelves, wine cellars, or a home theatre setup will increase costs. Many homeowners also choose to coordinate basement renovations with kitchen renovation or bathroom renovation projects to create a cohesive design throughout the home.
Cost Breakdown by Renovation Type
Basic Basement Renovation ($15,000 – $25,000)
- Painting walls and ceiling
- Installing new lighting

This option is great for turning your basement into a clean, usable space without major construction.
Mid-Range Basement Renovation ($30,000 – $50,000)
