Casa Loma's early 20th century homes along the Spadina corridor and hillside ravine lots contain some of Toronto's most characterful bathrooms — and some of its most demanding renovation conditions. Kopman Build has been working in these homes since 1999, bringing the trade coordination and technical rigour that century-old construction demands.
Casa Loma's hillside ravine lots and Spadina corridor estates were built in an era when bathrooms were large, plumbing was cast iron, and electrical ran through knob-and-tube. Renovating these spaces requires a contractor who can assess existing conditions honestly, plan around surprises, and execute at the finish level these homes deserve. Kopman Build does exactly that: thorough pre-construction investigation, proper membrane waterproofing on every shower, and trades who understand heritage-era construction.
The active full-renovation market in Casa Loma means clients are making significant investments. Dramatic lot topography — steep grades, ravine setbacks, and mature tree canopies — can complicate material staging and access. We account for these site realities in every schedule and estimate, so the project runs on time regardless of what the lot throws at us.
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 project is managed by someone who understands the craft — not just the sales pitch.

A detailed line-item estimate with allowances and contingencies, so you know the number before committing.
We manage all permit applications, engineering consultants, and approvals — nothing falls through the cracks.

Bathroom renovation costs in Casa Loma reflect the neighbourhood's large early 20th century homes and high finish expectations: powder rooms $20,000–$45,000; main bathrooms $35,000–$75,000; primary ensuites $60,000–$175,000+. Homes on the Spadina corridor often have generous bathroom footprints that support premium custom tile work, freestanding tubs, and steam showers. We provide a detailed estimate before any commitment is made.
Yes. Casa Loma's housing stock dates largely from the early 20th century, meaning we regularly encounter knob-and-tube wiring near bathroom circuits, cast iron drain stacks, galvanized supply lines, and plaster walls. These conditions are manageable but require experienced assessment upfront. We document existing conditions during our site visit and factor them into the estimate so there are no surprises once walls are opened.
Ravine-adjacent properties in Casa Loma can experience higher ambient moisture levels, which makes proper shower and wet-area waterproofing even more important. We use membrane waterproofing systems (Schluter KERDI or equivalent) on all shower assemblies, ensure proper exhaust ventilation is installed or upgraded, and select materials rated for high-humidity environments. Getting this right on the first renovation protects the wall assembly for decades.
Plumbing relocation and structural changes to bathroom walls in Casa Loma require City of Toronto permits. Many of these homes also sit on lots subject to ravine protection overlay or heritage designation considerations, which can affect exterior penetrations (exhaust venting) or structural modifications. We assess permit requirements on a project-by-project basis during the consultation and manage all applications on your behalf.
