Cost Breakdown of Basement Renovations in Toronto

Various factors can impact the cost of a basement renovation in Toronto. It’s essential to determine the purpose and desired outcomes of the renovation before creating a budget. Considerations such as moving walls, adding a bathroom, or installing windows or doors can lead to different price ranges. Here’s an overview of average costs for basement renovations in Toronto:

  • Turnkey renovation (without bathroom): On average, a full basement renovation costs between $25,000 and $40,000. This includes removing existing flooring, walls, and fixtures, remodeling the space according to your design, installing new flooring and walls, adding insulation, and painting.
  • Adding a bathroom: Installing a bathroom can add between $12,500 and $20,000 to your budget, depending on the size and desired features. Plumbing installation is a significant expense in this case.

Factors Affecting the Cost of a Basement Renovation

Several variables contribute to the overall cost of a basement renovation:

  • Framing: Wooden framing outlines rooms and defines the placement of doors, windows, and closets. The average cost for framing is between $15 and $30 per linear foot, including materials and labor.
