Basement Bathroom Options
A bathroom is what turns a finished basement from a nice room into a floor your family actually lives on. Whether you want a full three-piece, a powder room, or just a rough-in for later, we price it honestly and waterproof it properly.
A full basement bathroom in Ottawa typically runs around C$8,000–C$15,000 depending on whether the slab has to be cut and how far the plumbing has to travel. A rough-in only, the pipes set now so you can finish later, costs far less and is a smart way to keep the budget in check.
Three-piece additions
Rough-in only
Accessible / curbless
Heated floors
How We Add a Basement Bathroom
Below grade, the work that matters most is under the floor and in the walls.
-
Plumbing
Where gravity drainage isn’t available, we cut the slab to run new pipe or use an up-flush system, tied into your existing stack.
-
Ventilation
Proper exhaust that vents outside, so moisture doesn’t linger and the room stays healthy.
-
Waterproofing & finishes
Every wet area sealed behind the tile, the step that keeps a basement bathroom from becoming a mold problem, then fixtures, tile, and lighting.
Accessible & Aging-in-Place Basement Bathrooms
If this bathroom is for a parent, or for a basement in-law suite, we design it so they can use it safely and on their own. That means a curbless shower with no lip to trip on, grab bars set into solid blocking, lever taps, non-slip flooring, and a layout with room for a walker or wheelchair. It looks like a good bathroom, not a hospital, dignity and safety at the same time.
What a Basement Bathroom Costs in Ottawa
Expect roughly C$8,000–C$15,000 for a full bathroom, less for a powder room or a rough-in. The biggest cost drivers are slab cutting and how far the plumbing has to run. You’ll get an itemized estimate before any work starts, so the price is clear and there are no surprises mid-project.
