Basement Bathroom Finishing Ottawa
A finished basement is worth more — but a basement with a bathroom is worth significantly more. Whether you're creating a guest suite, a rental unit, a home gym, or a rec room for the kids, adding a bathroom to your lower level makes the whole space genuinely usable.
At Bath Up, we specialize in basement bathroom finishing for Ottawa homeowners. We manage the entire process — from plumbing rough-in and waterproofing to tile, fixtures, and the final inspection — so you don't have to coordinate multiple trades.
Most Ottawa homes already have plumbing rough-in stubbed into the basement floor. If yours does, the process moves quickly. If not, we handle that too.

Frequently Asked Questions
Does my Ottawa home already have basement plumbing rough-in?
Many Ottawa homes built after the 1980s have a capped plumbing rough-in in the basement floor. We check this during your consultation. If it's there, the project is significantly simpler and faster.
Do I need a permit to add a basement bathroom in Ottawa?
Yes — adding a bathroom typically requires a plumbing permit from the City of Ottawa. We handle the permit application and inspections as part of your project.
How long does a basement bathroom take to complete?
Most basement bathroom projects take 2 to 3 weeks from start to finish, depending on whether rough-in plumbing is already in place and the scope of tile work.
What if my basement is below the sewer line?
If your basement floor is below the municipal sewer line, an ejector pump (sewage ejector) is required to pump waste up to the sewer. We install these as part of the project where needed.
Can you add a basement bathroom as part of a larger basement renovation?
Yes. We focus exclusively on the bathroom portion and can coordinate timing with your general contractor if other basement work is happening at the same time.
