A standard 3-piece bathroom renovation in Oshawa typically takes 3 to 5 weeks. Larger master ensuites with custom tile work or structural changes can take 6 to 10 weeks, depending on material lead times and contractor availability.
Homeowners in the Durham Region can expect an ROI of 60% to 85%. Modernizing a bathroom is considered one of the highest-value upgrades in the local real estate market, often adding $15,000 to $35,000 to a home's resale value.
