Renovating a 1950s Etobicoke Bungalow Bathroom

Most of central Etobicoke — Alderwood, Eatonville, Richview, the streets around Princess-Rosethorn — went up in the 1950s and 60s, when Etobicoke was one of the fastest-growing municipalities in Canada. The bathrooms in those bungalows follow a template: one 4-piece room of roughly 40 square feet, wall tile set in a thick mortar bed over wire mesh, a cast iron drain stack, and supply plumbing that was standard-issue galvanized steel in anything built before about 1960.

A full renovation of one of these bathrooms typically runs $15,000 to $30,000 as of 2026 and takes two to three weeks. That covers full demolition, new waterproofing, porcelain tile, a new tub or shower, vanity, toilet, and lighting in the same layout. Our bathroom renovation cost guide for Toronto breaks those numbers down line by line.

One caution before demo day. Finishes from this era — vinyl floor tile, drywall compound, plaster — can contain asbestos, and Ontario's phase-outs only wrapped up around 1990. Testing a few samples costs a few hundred dollars. Certified abatement, if a sample comes back positive, typically runs $3,000 to $12,000. Skipping the test is not a savings; it is a gamble with your lungs and your schedule.

Galvanized steel pipe corrodes from the inside out. After sixty-plus years, the inner diameter of a half-inch line can shrink to a pencil's width — which is why so many Etobicoke bungalows have strong pressure at the outdoor tap and a weak dribble at the showerhead. If your hot water runs brown after a week away, that is the pipe, not the tank.

Once the walls are open, replacing the bathroom's branch lines with copper or PEX is a small marginal cost. Waiting and doing it later means opening finished walls all over again. A whole-home galvanized repipe runs $2,000 to $15,000 in the GTA depending on house size and access, and the bathroom is usually the hardest room to reach — so we do that leg during the renovation, every time.

Cast iron stacks are a judgment call. Many are still serviceable; some are scaled or cracked at the base. We inspect the exposed section during demolition and price a replacement only if it needs one. Keep permits in mind here: like-for-like fixture swaps do not need one, but moving or adding drains does — here is when a Toronto bathroom renovation needs a permit. Toronto's 2026 plumbing permit fee is $23.20 per fixture.

Plenty of 1950s bathrooms were built with a window as the only ventilation. Others got a fan added in the 1980s that dumps humid air straight into the attic — we find the frost-stained sheathing to prove it. With Toronto's humid summers, either setup grows mould. Part of every renovation we do in these homes is ducting a properly sized exhaust fan through the roof or an exterior wall; sizing the fan correctly matters more than the brand on the box.

Electrical is the other code gap. Original panels in these bungalows were 60 to 100 amps, bathroom receptacles usually lack GFCI protection, and the lighting often shares a circuit with two bedrooms. New circuits and GFCI protection are ESA-notification work — budget roughly $90 to $300 in ESA fees, normally built into the electrician's quote rather than billed separately.

While the floor is open, this is also the cheapest moment to add electric in-floor heating, typically $1,500 to $3,000. On a north-facing tile floor in February, few upgrades earn their keep faster.

Forty square feet does not leave much room to get creative, but you have three realistic routes.

• Keep the layout. Fixtures stay where they are, budget goes into finishes. This is the most cost-effective path, because relocating a toilet, drain, or shower valve adds $2,000 to $6,000 in plumbing work.
• Convert the tub to a walk-in shower. A basic bathtub-to-shower conversion runs $3,500 to $5,500; a custom tiled version with a glass panel lands $6,000 to $8,500. In bungalows where the owners plan to age in place — common in these neighbourhoods, where many original buyers stayed — a low-threshold shower is usually the smarter long game.
• Borrow space. The bedroom closet or hallway linen cupboard behind the bathroom wall can gain you a couple of feet for a wider vanity or a proper shower. That moves the project into permit territory and adds framing and drywall cost, so we only recommend it when the layout genuinely fails the household.

Most of our Etobicoke clients land on the first or second option. The room is small, but a smart same-footprint design makes it feel anything but.

Not everything from 1958 deserves the dumpster. The original cast iron tubs in these houses are heavier and more solid than most of what replaces them; if the layout keeps the tub where it is, refinishing at $400 to $800 beats a $2,000 to $5,000 replacement and keeps a genuinely better fixture.

Some details are worth echoing rather than preserving. Small hex or penny-round mosaic floors read as period-correct in a postwar bathroom and, in modern porcelain, install at standard tile rates of $10 to $25 per square foot rather than the $40-plus of natural stone. A solid wood vanity — original or new — warms up a small room better than any big-box cabinet.

What we do not keep: mortar-bed wall tile (it comes out in chunks, and there is no clean way to patch around it), original steel windows in the shower zone, and any wobbly original shut-off valve. The trick with a mid-century bathroom is separating character from liability, and sixty years of these houses have taught us which is which.

Pulling the numbers together for 2026: a same-layout full renovation typically lands between $15,000 and $30,000, a tub-to-shower conversion on its own runs $3,500 to $8,500, and layout changes or hidden plumbing surprises push toward the top of the range. Because these are pre-1990 houses, we recommend a 10 to 20 percent contingency — asbestos and corroded plumbing are the two most common budget-busters we find behind the tile.

When does a full renovation make sense over a refresh? If the plumbing is still galvanized, the fan vents nowhere, or the mortar-bed tile is cracking, cosmetic work is money layered over problems — gut it once and be done for decades. If a previous owner already updated the guts, a lighter scope with new fixtures and tile can be a legitimate choice.
