The Annex's late Victorian and Edwardian homes — built largely between the 1880s and 1910s near the University of Toronto — demand a bathroom contractor who understands century-old construction: plaster substrates, cast-iron plumbing, and floors that have settled for a hundred years. Kopman Build has been doing this work in Toronto since 1999, and we know what's inside these walls before we open them.
Renovating a bathroom in The Annex means working inside homes that predate modern building methods by a century. Plaster walls require a different substrate approach than drywall. Galvanized supply lines need replacing before new fixtures go in. Knob-and-tube wiring adjacent to a wet area has to be assessed and often rerouted. A contractor who skips the diagnostics will cost you far more when those conditions surface mid-project.
The neighbourhood's university proximity means a high proportion of Annex properties have been used as student rentals at some point — and many are now being converted back to single-family use. That history shows in deferred maintenance, patchwork plumbing, and bathrooms that were never properly waterproofed. We document every condition before the estimate, so there are no surprises.
Dustin Kopman founded the company in 1999 after growing up in construction through his family's firm, G&G Enterprise. Every Annex project is managed by someone who understands the craft, not just the contract.

Bathroom renovation costs in The Annex are consistent with Toronto's central neighbourhoods: powder rooms $18,000–$40,000; main bathrooms $30,000–$70,000; primary ensuites $50,000–$150,000+. Work in older Victorian and Edwardian homes often adds cost for addressing plaster walls, galvanized plumbing, and unlevel floors, so a thorough site assessment before estimating is essential.
Yes. The Annex's late Victorian and Edwardian housing stock — most built between the 1880s and 1910s — often has original plaster walls, cast-iron or galvanized pipes, knob-and-tube wiring adjacent to wet areas, and floors that have settled unevenly over a century. Proper assessment before demolition is critical to avoid discovering expensive surprises mid-project. Kopman Build evaluates all of these conditions during the consultation and builds them into the estimate.
Plumbing relocation and structural wall changes require City of Toronto building permits regardless of neighbourhood. In The Annex, heritage overlay designations on certain streets mean exterior changes require Heritage Permit review, but interior bathroom renovations are generally not affected by heritage restrictions. We assess permit requirements for every project and manage all applications on your behalf.
A standard bathroom renovation takes 4–8 weeks from demolition to final handover. In older Annex homes, allow additional time for any unforeseen conditions uncovered during demo — plumbing reroutes, substrate repairs, or levelling work can add one to two weeks. We build realistic timelines and communicate changes promptly.
