Home Renovations in Oshawa, Ontario

Floor & Bath Design has been renovating homes in Oshawa since 1989. From the century homes lining Simcoe Street to the new builds north of Taunton Road, we know this city's housing stock inside and out. Our team handles everything from kitchen and bathroom renovations to basement finishes and full home transformations — all managed in-house, one team from design through final walkthrough.

As a 7x Best of Houzz award winner, we've built our reputation on consistent quality, honest pricing, and the kind of local knowledge that only comes from three and a half decades of working in the same community.

Why Oshawa Homeowners Choose Us

Peter Mularczyk founded Floor & Bath Design with a straightforward approach: one company handles design, construction, plumbing coordination, electrical, tiling, cabinetry installation, and finishing. No subcontractor juggling, no communication gaps. That single-team model has served Oshawa homeowners well since the late 1980s.

Our design team includes an interior designer who specializes in balancing aesthetics with daily functionality, and an architectural specialist who ensures every structural modification is properly engineered and compliant with Ontario Building Code. This matters in Oshawa, where projects often involve removing walls in post-war bungalows, relocating plumbing in heritage homes, or converting basements — all work requiring proper structural assessment.

Oshawa's Diverse Housing Stock

Oshawa's residential landscape spans over a century of construction, and each era brings different renovation opportunities:

• Downtown Heritage Homes (1850s–1920s) — Century homes along Simcoe, King, and Centre Streets with rich architectural character. Renovations here require preserving original details — wide-plank floors, decorative moldings, built-in cabinetry — while modernizing kitchens and bathrooms. These homes often need electrical and plumbing updates alongside aesthetic improvements.
• Vanier & Eastdale (1940s–1960s) — Post-war ranch homes and bungalows with solid construction but dated layouts. The most common request: opening up compartmentalized kitchens, converting tub-shower combos to walk-in showers, and finishing basements. Infrastructure updates (plumbing, electrical, insulation) are frequently needed.
• Central Oshawa & Windfields (1970s–1990s) — Two-storey family homes with builder-grade finishes that have aged out. Kitchen renovations typically involve replacing laminate counters with quartz, updating cabinetry, and creating better flow between kitchen and living spaces. Master ensuite upgrades are the #1 bathroom request.
• Centennial & North Oshawa (2000s–present) — Newer builds near Taunton Road and beyond. While structurally sound, many owners are ready to replace builder-basic finishes with materials that match their taste. Pre-fab kitchen installations are particularly popular here — delivering a premium look faster and more affordably than custom.

Renovation Services in Oshawa

Kitchen Renovations

From cabinet refreshes to complete gut renovations with layout changes. Oshawa's post-war homes often have galley or L-shaped kitchens begging for an open-concept conversion. We handle everything: demo, structural modifications, plumbing, electrical, cabinetry, countertops, backsplash, flooring, and finishing. Our pre-fab kitchen option delivers comparable quality in weeks instead of months. Explore kitchen layout options.

Bathroom Renovations

Ensuites, main bathrooms, powder rooms, and accessible conversions. Oshawa homes built before 1990 often have dated 5×8 bathrooms with failing ventilation and aging plumbing. We transform these into modern, functional spaces — walk-in showers, floating vanities, heated floors, proper ventilation. Read about renovation vs. remodeling to understand your options.

Basement Renovations & Secondary Suites

Oshawa's proximity to Ontario Tech University and Durham College makes legal secondary suites a smart investment. We build code-compliant basement apartments with separate entrances, fire-rated separations, soundproofing, full kitchenettes, and properly drained bathrooms. For families, we create rec rooms, home offices, and additional bedrooms that add 500–1,000 sq ft of living space.

Oshawa Home Values & Renovation ROI

Oshawa has seen some of the strongest price appreciation in the GTA over the past decade, and the market rewards well-renovated homes. Kitchen renovations typically return 70–85% of investment at resale, while bathrooms return 60–75%. Renovated homes sell faster — often 2–3 weeks sooner than comparable unrenovated properties.

For Oshawa homeowners planning to sell within 2–5 years, we recommend focusing on kitchens and bathrooms first — these rooms have the highest impact on buyer perception and appraised value. Read more about how a kitchen remodel increases home value.

But most of our Oshawa clients renovate because they want to enjoy their home more, not because they're planning to sell tomorrow. A kitchen that works for how your family cooks, a bathroom that feels like a retreat, a basement that gives your teenagers their own space — that's what drives most projects.
