The smallest bathroom we ever finished was 32 square feet. A Centretown 1908 row house, second floor, original layout, no way to expand. The owners hated it. We rebuilt it as a fully custom space and it now reads as the most considered room in the house. Tiny bathrooms are not a problem to apologize for. They are a constraint that forces good design.
Most Ottawa small bathrooms come in three sizes: the 5x7 powder under the stairs, the 5x8 main on a 1950s bungalow, and the 6x9 second-floor in a Glebe semi. The seven moves below work in all three. The principle is the same: spend on fewer surfaces, but spend properly on those surfaces.
1. Float the vanity, never floor-mount
The single biggest visual difference between a designed small bathroom and a builder one is the vanity. A wall-mounted floating vanity makes the floor read continuous from one wall to the other, which makes the room read 30% larger. A floor-mounted vanity chops the floor into two visible zones.
What I spec for small bathrooms:
- Wall-mount vanity, 24" to 36" wide depending on space, in our shop or from Wetstyle if going off-the-shelf.
- White oak or rift-cut walnut veneer, no shaker doors, no inset hardware. The drawer fronts get cut for finger-pull recesses or push-to-open mechanisms.
- Counter integrated, single piece, no separate sink. Solid surface (Corian Glacier White) or honed quartz with an integrated trough sink.
- LED toe-kick light on a separate switch. Makes the vanity feel like it floats and provides a soft night light.
What drives the cost: a custom 30" floating vanity is priced by counter material and faucet selection, and it runs a step above an off-the-shelf Home Depot vanity. In a small space, where the vanity is the room's centrepiece, the upgrade earns its place.
2. Pick one tile, run it everywhere
Small bathrooms get killed by too many materials. Three different tiles, a vanity counter, a shower bench, a niche shelf, a feature wall, a transition strip. The eye reads chaos.
The fix is the opposite. One tile, two formats. Run a single 12x24 large-format porcelain on the floor and into the shower, then turn the same tile sideways onto the walls. The shower wall becomes the floor becomes the niche.
My current go-to is Mutina Mews 12x24 in Cinder, a soft warm grey with subtle vein. A mid-range porcelain by the square foot. Run continuously, the room reads like a single carved space, and buying one tile in volume is more economical than chasing three.
3. Make the shower bigger by removing the door
In a small bathroom, the standard glass-door shower steals visual space. The door swings into the room, the frame chops the field of view, and the silicone seam at the floor reads as a hard boundary.
The wet-room approach removes all of that. No door. No threshold. The whole bathroom slopes 1/4" per foot toward a linear drain at the back of the shower. A single fixed glass panel divides the shower zone, with a 24" walk-in opening.
It costs more than a standard shower because waterproofing has to extend across the entire bathroom floor and the slope work is more complex, but it is the move that makes a 5x8 bathroom feel like a hotel. We break that adder out as its own line so you can weigh it.
The walk-in wet-room shower is the single highest-impact move in a small bathroom. It removes the visual barrier and gives the eye permission to read the whole room as one space.
4. Pick a paint colour with depth, not a "bathroom white"
White bathrooms are the safest, most predictable, lowest-impact choice. In a small space they read sterile, cheap, and forgettable. Colour does the opposite. A warm muted colour with depth makes a small bathroom feel like a jewel box.
Three colours I install in Ottawa small bathrooms over and over:
- Farrow & Ball Setting Plaster (No. 231): pinkish nude. Reads warm and flattering on skin. Especially good in north-facing bathrooms.
- Benjamin Moore Tarrytown Green (HC-134): deep saturated green. Pairs with brass and white oak. Reads moody and considered.
- Benjamin Moore Hale Navy (HC-154): classic deep navy. Reads sharper than green, especially good with chrome or polished nickel.
Paint walls, ceiling and trim the same colour, all in eggshell. The continuous colour field is what gives a small bathroom its drama.
5. Mirror the full wall, not a 30-inch frame
A vanity-width framed mirror is the builder default. The designed move is a full wall, edge to edge, floor to ceiling or to within 6 inches of each. The room visually doubles in width.
What this looks like in practice:
- Mirror cut to size and bonded directly to the wall behind the vanity, no frame.
- Sconces mounted on the mirror itself, drilled through, on either side of where the head sits when standing at the sink. Cedar & Moss bend sconces in unlacquered brass are a current favourite.
- The medicine cabinet, if needed, is recessed into the wall behind the mirror with a dedicated panel cut.
A 60x60 mirror cut, polished, and bonded by a glass shop is a modest line item. Worth it to double the perceived width of the room.
6. Pick fixtures in one finish, no mixing
This is where small-bathroom design dies most often. Chrome faucet, brushed-nickel showerhead, oil-rubbed-bronze towel hook, brass mirror. The eye reads it all.
Pick one finish, hold the line. My recommendations:
- Unlacquered brass: warmest, highest-impact, ages naturally with patina. Brizo Levoir or Waterworks Henry. The premium end of the faucet/shower-set range.
- Matte black: most forgiving on dust and water spots. Brizo Litze or Riobel Pallace. A mid-range set.
- Polished nickel: sharper than chrome, warmer than chrome, and the priciest of the three. Waterworks Henry or Newport Brass.
Whatever finish you pick, every single piece of metal in the room matches: tap, shower trim, toilet flush, towel hook, drain cover, hinges, vent cover. Skipping one piece kills the discipline.
7. Hide the toilet, do not feature it
The toilet should be the last thing you see when you walk in. Position it on the wall closest to the door, against the corner, never on the wall opposite the entry. Where possible, partial-wall it behind a half-height knee wall to break the sight line from the door.
Two upgrades that change how a toilet reads in a small bathroom:
- Wall-hung toilet with concealed tank in the wall (Geberit Sigma carrier system, Toto Aquia bowl). Adds a defined materials-and-labour line. Frees 6 to 8 inches of floor depth and visually doubles the perceived floor.
- Skirted floor-mount toilet if a wall-hung is not possible. Toto Aquia IV, smooth flush profile, no visible trapway, at a lower cost than the wall-hung option.
The 32-square-foot Centretown bathroom, line by line
5x6.5 footprint, no expansion possible. We did Mutina Mews 12x24 floor and walls in Cinder, walk-in wet-room shower with a single fixed glass panel, custom 24" floating white-oak vanity with integrated Corian sink, Geberit wall-hung toilet, Brizo Litze tap and shower trim in unlacquered brass, full-wall bonded mirror with two brass sconces, walls and ceiling in Setting Plaster. Every one of those selections was specced in a fixed written proposal before work began. Owners say guests now linger in the bathroom.
What drives the cost of a designed small bathroom in Ottawa
For a 5x8 small bathroom in Ottawa, a complete gut and rebuild including all seven moves above breaks into these scope lines, each itemized in our written proposal:
- Demo and waterproofing
- Plumbing rough and finish
- Electrical rough and finish
- Tile material and install
- Custom vanity, counter, mirror
- Fixtures and faucets
- Toilet (wall-hung)
- Drywall, paint, trim
- Project management, permits, contingency
A designed 5x8 lands above a stock builder rebuild, and the gap goes almost entirely into the custom vanity, the wet-room waterproofing, the single continuous tile, and the matched fixtures. Each of those is a choice you make line by line with us, so you control where the budget goes and worth every dollar in a space you use twice a day for the next 20 years.
If you are planning a small bathroom rebuild, our bathroom renovation page walks through how the design phase actually sequences and what the realistic timeline looks like in Ottawa for a tight bathroom that needs permitted plumbing changes. Small bathrooms reward design discipline more than any other room in the house. Spend on fewer surfaces, but get them right.
