Leaside's 1940s–1960s brick bungalows and two-storey homes are in the midst of a major renovation wave — and the bathroom is almost always part of it. Kopman Build has been delivering precision bathroom renovations in this tight-knit family neighbourhood for over 25 years, from standalone ensuite rebuilds to bathrooms added within full second-storey conversions.
Leaside's housing stock presents a specific set of challenges: original 1940s and 1950s cast iron drain stacks, galvanized supply lines, compact floor plans, and bathrooms that were designed for a different era. Renovating them properly — especially when expanding into a second storey — requires a contractor who understands how these homes are built and what it takes to modernize them without cutting corners.
Kopman Build is one of the most active contractors in Leaside's bungalow-to-two-storey conversion market. We routinely plan and build new primary ensuites and secondary bathrooms as part of full upper-floor additions. That experience means we know where the traps are: plumbing stack conflicts, header locations, and structural constraints that affect bathroom layout before a single tile is set.
Dustin Kopman founded the company in 1999 after growing up in construction through his family's firm, G&G Enterprise. Every Leaside project is managed by someone who has been on the tools — not just in the sales meeting.
Full primary bathroom transformations — walk-in showers, freestanding tubs, double vanities, radiant floors, and custom tile work sized for Leaside's layout realities.
Family bathroom gut-and-rebuilds with durable materials and smart layouts that work within original bungalow floor plans.
Statement powder rooms with elevated tile, designer fixtures, and custom vanity millwork — common in Leaside's front-entry conversions.
New bathroom rough-ins and full builds as part of bungalow-to-two-storey conversions — including plumbing stack extensions and all finishes.
In-floor radiant electric heating installed under tile — a popular upgrade in Leaside ensuites and main bathrooms.
Converting tub/shower combos to walk-in showers with proper waterproofing, linear drains, and custom tile — including curbless formats.

We manage all City of Toronto permit applications, engineering consultants, and approvals — nothing falls through the cracks.
Full-time site supervision, weekly updates, and open-book cost tracking throughout the project.
Structured handover with all documentation, warranties, and a 12-month attendance window post-completion.
Bathroom renovation costs in Leaside typically run: powder rooms $18,000–$40,000; main bathrooms in original 1940s–1960s bungalows $32,000–$72,000; primary ensuites — especially in second-storey additions — $55,000–$160,000+. Tight original floor plans and older plumbing stacks can add complexity to any gut-and-rebuild. We provide a detailed line-item estimate before you commit.
Yes — and it's one of the most common scopes we manage in Leaside. Bungalow-to-two-storey conversions routinely include a new primary ensuite and a secondary bathroom on the upper floor. We handle the full scope: structural, plumbing stack extension, rough-in, and all finishes. Planning the bathroom layouts early in the addition design avoids costly retrofits later.
Leaside homes built in the 1940s and 1950s often have original cast iron drain stacks, galvanized supply lines, and single-stack plumbing configurations not suited to modern bathroom layouts. Relocating fixtures or adding a bathroom on a new upper floor requires careful planning around existing stack locations. We assess and document existing conditions at the outset so there are no surprises mid-project.
Plumbing relocations, new bathroom rough-ins, and any structural changes to walls require a City of Toronto building permit. A straightforward like-for-like replacement of fixtures in the same locations typically does not. For bathrooms added as part of a second-storey addition — the dominant project type in Leaside — the permit is included in the broader addition scope. We manage all permit applications and inspections.
