Humber Valley's 1950s and 1960s homes — set on generous ravine lots backing onto the Humber River, steps from the golf course — are ideal candidates for full-scope bathroom transformations that honour the neighbourhood's heritage character while delivering modern performance. Kopman Build has been executing premium Etobicoke bathroom renovations since 1999, managing every trade and every decision with the care these properties deserve.
Humber Valley is a premium renovation market, and homeowners here expect contractors who understand the full scope of what these mid-century homes require. Behind the original tile and the cast-iron tubs are aging plumbing stacks, galvanized supply lines, and early-generation electrical circuits that need to be addressed properly — not worked around. Kopman Build assesses every hidden condition before finalizing scope, so there are no surprises once walls are opened.
Ravine-adjacent properties also carry elevated humidity considerations that make proper shower waterproofing non-negotiable. We use full membrane systems — Schluter KERDI or equivalent — on every installation, and ventilation is engineered at the design stage rather than afterthought. These are not details that cut-rate contractors manage correctly.
Dustin Kopman founded the company in 1999 after growing up working in construction through his family's firm, G& G Enterprise. That hands-on background means every Humber Valley project is managed by someone who understands the craft, the neighbourhood, and the premium standard these homes demand.

Bathroom renovation budgets in Humber Valley typically run higher than the Toronto average, reflecting the premium character of the neighbourhood. Powder rooms start at $20,000–$45,000; main bathrooms $35,000–$80,000; primary ensuites in the large 1950s–60s homes here commonly run $60,000–$175,000+. We provide a detailed line-item estimate before any commitment is made.
Homes built in this era often have galvanized steel supply lines, cast-iron drain stacks, knob-and-tube or early-generation electrical wiring, and plaster-over-lath wall assemblies. A bathroom renovation is an ideal time to address all of these: upgrade supply and drain plumbing, rewire the bathroom circuit to current ESA code, and rebuild wall assemblies with proper cement board and waterproofing membrane before tile goes in. We assess every hidden condition before finalizing scope.
Any plumbing relocation, electrical panel upgrades, or structural wall changes in an Etobicoke home require City of Toronto permits. Many Humber Valley bathroom projects involve moving fixtures or upgrading aging plumbing — we handle all permit applications and inspections so nothing falls through the cracks.
Ravine proximity can mean elevated humidity levels in basements and lower floors, making proper waterproofing even more critical in any bathroom renovation. We use full membrane systems — Schluter KERDI or equivalent — on every shower installation, and assess ventilation requirements carefully in these settings. If you are adding a basement bathroom, we also evaluate drainage grades and sump conditions as part of scoping.
