"How much will this cost?" is the first question every homeowner asks — and the hardest to answer without seeing the project. But if you're in the early planning stages, having realistic ranges helps you budget smarter and avoid surprises. Here's an honest breakdown for the Niagara Region in 2026.
Every project is different. These ranges reflect typical costs in the Niagara Region for work completed by a licensed, insured general contractor — not a handyman or DIY. Material choices, project scope, permits, and site conditions all affect the final number. Get a proper quote before you budget.
Bathrooms are one of the most popular renovations — and one of the best returns on investment. Costs vary significantly depending on the size of the bathroom, the tile selected, and whether plumbing needs to be moved.
| Scope | What's Included | Typical Range |
|---|---|---|
| Basic refresh | New tile, vanity, toilet, fixtures — no layout changes | $8,000 – $15,000 |
| Mid-range reno | Custom shower, full tile, new layout, quality fixtures | $15,000 – $30,000 |
| High-end / full custom | Large format tile, heated floors, glass enclosure, premium finishes | $30,000 – $60,000+ |
| Ranges are for Niagara Region, 2026. Permit fees not included in all cases. | ||
Kitchen renovations have a wide cost range because the scope can vary enormously — from new countertops and a backsplash, all the way to a full gut and reconfiguration with new plumbing, electrical, and an island.
| Scope | What's Included | Typical Range |
|---|---|---|
| Cosmetic update | New backsplash, countertops, hardware, paint | $5,000 – $15,000 |
| Cabinet & surface reno | New cabinets, countertops, backsplash, appliances, flooring | $20,000 – $45,000 |
| Full gut renovation | Full reconfiguration, plumbing, electrical, custom cabinetry | $50,000 – $100,000+ |
| Cabinet quality is often the biggest cost driver. Custom vs. stock cabinets can differ by $20,000+. | ||
Finishing an unfinished basement adds livable square footage and significantly increases your home's value. Costs depend heavily on whether the space is just being finished, or if you're adding a bathroom, bedroom, or secondary suite.
| Scope | What's Included | Typical Range |
|---|---|---|
| Basic finish | Framing, drywall, flooring, electrical, no bathroom | $25,000 – $45,000 |
| With bathroom | Full finish + 3-piece bathroom, egress window | $45,000 – $75,000 |
| Secondary suite / in-law | Full apartment including kitchen, bedroom, bathroom, separate entry | $75,000 – $130,000+ |
| In Ontario, basement apartments require a building permit. Plitka handles this for you. | ||
Always budget for waterproofing assessment before finishing a basement. Discovering a water issue after drywall is up is an expensive lesson. A good contractor will flag this during planning.
Adding square footage to your home is a major investment — but it typically delivers strong returns and avoids the cost and disruption of moving. In Niagara, additions require a building permit and BCIN drawings, which Plitka handles in-house.
| Type | Notes | Typical Range |
|---|---|---|
| Single room addition | ~200–400 sq ft, framing, exterior, interior finish | $60,000 – $120,000 |
| Two-storey addition | Significant structural work, full interior finish | $150,000 – $300,000+ |
| Garage conversion / addition | Insulation, HVAC, interior finish, permits | $40,000 – $90,000 |
| Cost per square foot for additions in Niagara typically ranges from $200–$350+ depending on finishes and complexity. | ||
