Straight answer on Durham Region first

Osoba Renos & Design works out of Mississauga, which puts Oshawa 60 to 80 minutes east on the 401. We do take Durham work, and we quote it case by case with the commute built into the proposal instead of billing a travel fee. For a full bathroom, an ensuite, or two rooms in one visit that usually prices sensibly. For a single powder room it usually does not, and we will tell you so rather than pad the quote. See our 2026 bathroom cost ranges before you call.

Oshawa neighbourhoods and what we find there

  • Bathroom renovation in Windfields & north Taunton

    Post-2005 detached subdivisions near Ontario Tech. Square walls, modern plumbing, builder-grade ensuites now old enough to replace. Straight rebuilds with few surprises.

  • Bathroom renovation in Samac & Eastdale

    1970s to 1990s detached and semis. Main bathrooms in the 5x8 footprint, where the biggest gain is usually a tub-to-shower conversion rather than a like-for-like swap.

  • Bathroom renovation in McLaughlin & central Oshawa

    Pre-war and post-war housing near downtown. Expect cast-iron waste stacks, galvanised supply, and occasional subfloor rot at the flange. We quote those repairs as unit rates up front.

  • Bathroom renovation in Donevan & Lakeview

    Post-war bungalows and split-levels in the south end. Small bathrooms, low ceilings in some, and a lot of original plumbing still in service.

Bathroom renovation questions - Oshawa

Do you actually take work in Oshawa?
Yes, but honestly: Oshawa is outside our regular no-surcharge service area. Our shop is in Mississauga, which is 60 to 80 minutes east depending on the 401. We quote Durham Region jobs case by case and build the commute into the proposal rather than billing a separate travel fee. For a single powder room the numbers rarely work; for a full bathroom, an ensuite, or two rooms at once, they usually do.
How much does a bathroom renovation cost in Oshawa?
A standard full rebuild runs $13,000-$20,000 in 2026, and a primary ensuite $20,000-$32,000. Older central Oshawa homes land at $16,000-$26,000 once cast-iron stack replacement and subfloor repair are included. Durham travel is factored into the quote rather than added as a line item.
Do I need a City of Oshawa permit?
Yes when plumbing fixtures are relocated, a wall moves, or a new electrical circuit is added. No for a like-for-like replacement in the same positions. We file with the City of Oshawa building department and book the rough-in and final inspections.
Which Durham communities do you cover?
Oshawa, Whitby, Ajax, Pickering, and Courtice, all on the same case-by-case basis. Pickering and Ajax are the shortest drive and price closest to our standard ranges; Oshawa and Courtice carry the longest commute.
How long does an Oshawa bathroom renovation take?
Two to three weeks for a standard rebuild and three to five for a primary ensuite, the same as anywhere else in the GTA. Older homes add three to five days once the stack and subfloor repairs are in scope. Permit review adds four to six weeks up front where plumbing moves.
Is it cheaper to hire a local Oshawa contractor?
On travel, yes. On the parts that matter — waterproofing system, licensed trades, warranty terms, a fixed price with written allowances — compare the quotes line by line rather than on the headline number. If a local contractor matches the spec for less, take it. We would rather lose a quote than win a job on a commute nobody enjoys.
