To successfully tackle a small bathroom renovation in East York or the Danforth, homeowners must focus on clearing floor space rather than expanding the classic 5×8 footprint typical of 1910–1940s homes. The most effective space-saving bathroom ideas for these tight layouts include converting bulky tubs into walk-in glass showers, installing wall-mounted vanities, carving out recessed wall niches for storage, and upgrading to pocket doors. While these concepts look effortless on paper, older home renovations in Toronto always hide complex realities behind the plaster.
Key Takeaways
- Most second-floor bathrooms in pre-war East York and Danforth homes measure about 5 ft × 8 ft; practical gains come from clearing floor area, not adding it.
- A tub-to-walk-in-shower conversion is the largest single gain, but it usually means upgrading the 1½-inch tub drain to a 2-inch drain to accommodate modern curbless setups.
- Wall-mounted vanities, wall-hung toilets, recessed niches, and pocket doors all depend on what already occupies the wall: drain stacks, wiring, ducts, and framing.
- Moving or removing any wall in a 1920s semi-detached home typically requires a City of Toronto building permit, an ESA electrical inspection, and a structural engineer.
- Because drain stacks and bearing walls run through the whole house, a second-floor bathroom renovation is often the right time to plan a main-floor remodel.
5 Space-Saving Renovation Ideas for a Tiny Bathroom
1. Convert the Tub to a Walk-In Glass Shower
Replacing a 30 × 60 in. tub with a walk-in shower in the same footprint does not add floor area, but a frameless glass panel removes the visual barrier a tub surround creates, making the full length of the room visible from the door. Where the layout allows, shortening the shower to 48 in. frees a foot of space for a wider vanity.
What it involves in an older home:
- Drain sizing. While the Ontario Building Code permits a 1½-inch drain for a single showerhead, upgrading to a 2-inch drain is highly recommended—and required for high-flow fixtures or curbless designs—to prevent overflowing. This usually means replacing the drain line back to the main stack.
- Curbless entries. A level-entry shower on a second floor means recessing the base into the joists or building up the floor around it. Recessing usually requires reinforcing joists, which is engineering work, not just carpentry.
- Waterproofing. Glass exposes the tile to direct spray every day. A bonded membrane and a correctly sloped substrate keep water out of the kitchen ceiling below. Our tiling and waterproofing method explains the exact system we use to ensure longevity.
2. Mount the Vanity on the Wall
A wall-mounted vanity exposes the floor beneath it, which makes a 5-foot-wide room read as wider and simplifies cleaning.
What it involves in an older home:
- Blocking. Wall-mounted fixtures carry their load into solid blocking between studs. In a lath-and-plaster wall, that means opening the wall completely, which is also the practical moment to replace corroded galvanized supply lines.
- Electrical. Under-vanity lighting, mirror lighting, or a new receptacle near the sink must be GFCI-protected, filed with the Electrical Safety Authority (ESA), and inspected.
3. Build Storage Into the Walls With Recessed Niches
Recessed niches and medicine cabinets are the most effective tiny bathroom storage ideas because they utilize depth the room already has. A niche between studs is about 3½ in. deep and 14 in. wide; a recessed medicine cabinet adds 4 in. of storage over the vanity without projecting into the room.
What it involves in an older home:
- Wall selection. Niches strictly belong on interior walls. Cutting into an exterior wall in Toronto’s climate removes insulation and breaks the air/vapour barrier, inviting hidden condensation behind the tile.
- Occupied cavities. Stacks, vents, and wiring run through many bathroom walls. A niche cannot go where the stack is, and relocating a plumbing vent requires a permit.
- Framing. Stud spacing in older homes is rarely even, so niche widths follow the framing, not the tile layout, and are confirmed once the wall is open.
4. Replace the Swing Door With a Pocket Door
A standard 30-inch swing door sweeps roughly 5 square feet—an eighth of a 40-square-foot room. A pocket door returns that area, which often allows for a wider vanity or better fixture placement.
What it involves in an older home:
- The receiving wall. The existing wall must be demolished and rebuilt to house the pocket cage. This requires a clear cavity roughly twice the door’s width with no plumbing, ducts, or wiring inside it.
- Bearing walls. If the wall carries load, the wider rough opening needs an engineered header, and a structural engineer’s letter becomes part of the permit file.
- Hardware. A solid-core door on high-quality track hardware is essential to avoid the rattling and derailing that gave older pocket doors a bad reputation.
5. Borrow Space From an Adjacent Closet or Hallway
When the first four ideas are not enough, the remaining option is to change the footprint. Absorbing a hall linen closet, a bedroom closet, or a foot of an oversized landing can turn a 5 × 8 room into a 6 × 8 or 5 × 10 room. Our guide to planning the layout of your bathroom covers how fixture clearances change when the footprint expands.
Moving a wall, even a partial one, in a 1920s semi-detached home reaches into the framing, the mechanical systems, and the permit process.
Where “Opening Up the Bathroom” Becomes Structural Work
Homeowners who start with sightlines and storage usually reach the same conclusion: the wall between the bathroom and the hall closet is the real obstacle. While removing part of it looks like a simple day of demolition, in an East York or Danforth semi, it involves four trades before a single tile is chosen.
- Structure: Interior walls running perpendicular to the floor joists frequently carry attic or roof loads. Structural wall removal in Toronto requires an engineer to confirm the load path, size a beam (usually LVL or steel), and detail posts down to a footing. The City issues permits for structural alterations only against engineer-stamped drawings.
- HVAC: Many pre-war homes were converted from gravity heating to forced air, with ducts panned into the same wall cavities you want to open. Rerouting them changes airflow on both floors.
- Electrical: Opening walls exposes knob-and-tube or undersized circuits that must be brought up to the current Ontario Electrical Safety Code.
- Plumbing: The bathroom’s drain stack and vent run down through a main-floor wall, usually behind the kitchen or hall, straight to the basement.
A second-floor bathroom and a main floor gut and remodel can often become necessary to achieve a project’s goal. If the stack must move for the bathroom, and the main-floor wall it runs through is one you eventually want removed for an open kitchen, the two projects share the engineering, the permit, and the open walls. Doing them separately means paying to open the same walls twice.
| Space-Saving Idea | The Space/Visual Benefit | What It Requires Behind the Walls | Structural & Permit Impact |
| 1. Walk-In Glass Shower | Removes visual barriers; opens up sightlines. | Upgrading the 1½” tub drain to a 2″ shower drain; recessing the base into joists. | Medium: Requires plumbing permits and potential joist reinforcement. |
| 2. Wall-Mounted Fixtures | Exposes floor space to make the room feel wider and deeper. | Opening lath-and-plaster walls to install solid wood blocking and re-running supply lines. | Low to Medium: Mostly carpentry and plumbing/electrical updates. |
| 3. Recessed Wall Niches | Adds 3.5″ to 4″ of storage depth without encroaching on the room. | Must dodge existing vent stacks/wiring. Must be on an interior wall to protect the vapour barrier. | Low: Unless a plumbing stack needs to be relocated. |
| 4. Pocket Door | Recovers roughly 5 sq. ft. of floor space lost to a door swing. | Requires a double-width empty wall cavity rebuilt free of ducts, pipes, or wiring. | Medium to High: If the wall is load-bearing, it requires an engineered header. |
| 5. Borrowing Space | Physically expands the 5×8 footprint into a closet or hallway. | Reaches into core mechanicals (HVAC ducts, electrical, plumbing stacks). | High: Requires engineering, building permits, and multi-trade coordination. |

Frequently Asked Questions
Can you fit a walk-in shower in a 5×8 bathroom?
Yes. A 5 ft × 8 ft bathroom fits a standard 30 × 60 in. walk-in shower in the original tub position, or a 32 × 48 in. shower if a wider vanity is the priority. The main constraint is not room size, but upgrading the plumbing to properly drain the shower without overflowing.
Do I need a building permit to renovate a bathroom in Toronto?
Not for a purely cosmetic like-for-like refresh. Replacing vanities, tiling, and painting do not require a permit. However, a City of Toronto building permit is required when plumbing is added or relocated, when a tub is swapped for a shower (altering the valve/drain), or when structure such as joists or bearing walls is altered. Electrical work is separate and must always be filed with the ESA.
How much does a small bathroom renovation cost in East York?
Cost depends less on the room’s square footage than on what changes inside the walls. A visual refresh with fixtures in their original positions sits at the low end. Relocating a drain, replacing a cast-iron stack, upgrading electrical, or moving a wall each add a distinct cost line.
Does removing the bathtub hurt resale value?
It can if the home is left without any tub. Buyers with young children generally expect at least one bathtub. If a second bathroom keeps a tub, converting the upstairs one to a shower is rarely a concern. In a one-bathroom home, weigh your daily use against resale, and consider keeping the plumbing roughed-in so a tub could easily be reinstated later.
Can a pocket door be installed in a load-bearing wall?
Yes, but not as a simple hardware swap. The pocket needs a rough opening roughly twice the door’s width. In a bearing wall, that opening requires an engineered header with posts carrying the load to the floor below. A structural engineer must confirm the load and size the header for the building permit application.
How do I know if a wall is load-bearing in an older Toronto home?
Walls that run perpendicular to the floor joists, sit above a basement beam or post line, or align with a wall on the floor below are likely bearing. In semi-detached homes, the masonry party wall carries load, and interior walls that continue vertically through the main floor and basement often do as well. Only a structural engineer’s assessment reliably confirms this.
What problems come up most often in 1920s Toronto bathroom renovations?
Corroded galvanized supply lines, cast-iron stacks with failed joints, active knob-and-tube wiring, joists previously notched by old plumbing work, plaster hiding uneven framing, and floors completely out of level. Because these are confirmed only after demolition, older home renovations should always carry a contingency budget.
How long does a small bathroom renovation take?
A like-for-like renovation with fixtures in their original positions typically takes two to four weeks of on-site work once materials are secured. Relocating plumbing, replacing a stack, or upgrading electrical extends that schedule, and any structural change adds engineering and permit review time prior to construction.
