How Much Does It Cost to Finish a Basement in Barrie?
A finished basement is one of the best ways to add real living space to a Barrie or Innisfil home. Most basements land between roughly $30,000 and $55,000 before HST, depending on size and what you put in.

| Project | Typical cost (before HST) | What’s included |
|---|---|---|
| Base finish (~700 sq ft basement) | ~$33,000 all-in | Framing, insulation, drywall, electrical, flooring, ceiling, trim, paint and doors. Scales with square footage. |
| Typical full project range | $30,000 – $55,000 | Where most Barrie basements land, depending on size and what goes in. |
| Add a 2-piece powder room | from ~$8,500 | Smallest bathroom add; no shower, simpler rough-in. |
| Add a full 3-piece bathroom | ~$22,000 – $28,000 | Concrete cutting plus an ejector or sump pump swing the rough-in cost. |
| Egress window | quoted separately | Legally required when adding a bedroom. |

The short answer: what most Barrie basements cost
For a straightforward finish, a typical Barrie basement of around 700 sq ft comes in near $33,000 all-in before HST. Bigger spaces and added features push that up, which is why most basements we quote land somewhere between $30,000 and $55,000 or more.
That range is wide on purpose. A clean, open rec room costs far less than the same square footage carved into a bedroom, a bathroom, and a wet bar. The best way to skip the guesswork is our free cost estimate, which gives you a tailored ballpark based on your actual basement.
Every quote we write is itemized line by line, so you can see exactly where the money goes. And once you approve it, the price doesn’t move unless you ask for a change, no surprise overages.
What the base finish includes
The bulk of a basement project is the base finish, and it scales with your square footage. That covers framing, insulation, drywall, electrical, flooring, a ceiling (drop or drywalled), trim, paint, and interior doors.
This is the foundation of a usable, comfortable room. If you want to understand the framing and drywall side in more detail, our Drywall & framing service page walks through how those stages come together.
Because the base finish is mostly labour and materials per square foot, a larger basement costs more simply because there’s more to frame, board, and finish, not because anything fancier is going in.
Adding a bathroom: the biggest single decision
A bathroom is the single largest add to a basement budget, and the price swings a lot depending on what you build. A 2-piece powder room starts around $8,500. A full 3-piece bathroom with a shower runs roughly $22,000 to $28,000.
What drives that gap is the plumbing rough-in. Cutting into the concrete floor to run new drains, and adding an ejector or sump pump if your drain sits below the sewer line, is real work that adds real cost.
If a basement bathroom is on your wish list, it’s worth deciding early. It shapes the layout and the budget more than any other choice you’ll make down there.
Big-ticket items we arrange and quote separately
Some parts of a basement project sit outside the standard finish, so we arrange and quote them separately rather than burying them in a vague allowance. That keeps your main quote honest and easy to read.
These include an egress window (legally required if you’re adding a bedroom), waterproofing, an electrical-panel upgrade, and the city permit. Not every basement needs all of them, which is exactly why we don’t pad the base price to cover things you may not require.
Quoting them on their own means you only pay for what your basement actually needs, and you can see each item clearly before you decide.
