A wall-hung vanity, sometimes called a floating or wall-mount vanity, fastens to the wall with nothing touching the floor. The look is clean, the floor is easy to mop, and you set the counter at the height that suits your household. The trade-off is that fit matters more, not less: the cabinet hangs from the wall and the plumbing usually hides behind it, so a sizing mistake is hard to disguise. This guide walks through standard wall-hung vanity sizes and dimensions, how to measure properly, the clearances that keep a bathroom usable, and the fit mistakes we see most often from buyers across Canada.
Standard wall-hung vanity sizes
Most brands, from European lines such as Duravit and Villeroy & Boch to collections from ICO Bath and Tenzo, size wall-hung cabinets within a fairly predictable range. Canadian spec sheets typically list both millimetres and inches.
| Width range | Approximate imperial | Typical use |
|---|---|---|
| 400 to 600 mm | 16 to 24 in | Powder rooms and compact two-piece baths |
| 600 to 800 mm | 24 to 32 in | Standard single-sink bathrooms |
| 900 to 1200 mm | 36 to 48 in | Larger single-sink layouts with storage to spare |
| 1200 to 1800 mm | 48 to 72 in | Double-sink primary bathrooms |
Depth is the quieter number, and often the more important one. Full-depth wall-hung vanities commonly run about 450 to 550 mm front to back, roughly 18 to 22 inches. Compact models in the 330 to 400 mm range exist for exactly the tight condo bathrooms and narrow powder rooms you find from downtown Vancouver to Montreal. Cabinet height, the vertical size of the box itself, usually lands between about 400 and 650 mm, but with a wall-hung unit the height that matters is where you mount it, and that part is your call.
Measure the space before you fall for a style
- Measure wall width at counter height. Walls are rarely perfectly straight, and baseboards do not matter to a floating cabinet. Measure where the vanity will actually sit, in at least two spots.
- Locate the plumbing. Wall-hung vanities work best when the drain exits through the wall rather than the floor. A floor drain can often be adapted, but the trap may stay visible in the open space below the cabinet.
- Find the structure. A wall-hung vanity carries its full weight, plus counter, sink and whoever leans on it, into the wall. Locate the studs, and budget for solid blocking if the framing does not line up with the mounting points. Older housing stock in cities like Halifax or Winnipeg often needs the wall opened for proper backing.
- Map the obstructions. Door swings, the toilet, tub decks, window casings, light switches and heat registers all shrink your usable wall. In a Canadian winter you do not want a cabinet blocking the register that keeps the room, and the pipes behind it, warm.
- Check the depth against traffic. Picture the front edge of the vanity at the listed depth. If it will clip a swinging door or squeeze the path to the shower, choose a shallower model.
Clearance guidelines that keep the room usable
Exact minimums come from the plumbing and building codes in your province and municipality, most of them based on the National Plumbing Code of Canada, so your local building department, plumber or inspector is the final word. That said, a few widely used planning guidelines make a good sanity check while you shop:
- Keep the centreline of the basin a comfortable distance from any side wall. Around 380 mm, or 15 inches, is a common planning minimum, and more feels noticeably better.
- Leave generous clear floor space in front of the vanity. Roughly 750 mm of standing room is a comfortable target; much less and the room starts to fight you every morning.
- Do not crowd the toilet. Leave breathing room between the vanity edge and the fixture beside it, for cleaning and for code.
- Account for drawer extension. A fully open drawer can project nearly the cabinet depth again, so check that it clears the toilet and tub.
Common fit mistakes
- Buying the wall, not the usable wall. A 900 mm vanity does not fit a 900 mm wall once you account for door casings, a light switch or the tile return in a corner. Leave working margin on both sides.
- Ignoring what shows underneath. The open space below a floating vanity puts the flooring, the wall finish and any exposed plumbing on display, so plan for finished surfaces under and behind the cabinet.
- Trusting drywall alone. Hollow-wall anchors are not a mounting plan. Wall-hung cabinets need studs or blocking, full stop.
- Running supply lines through a cold exterior wall. In most of Canada, moving plumbing into an exterior wall to suit a new vanity location invites frozen pipes. Keep the plumbing on an interior wall where possible, and let your plumber weigh in early.
- Guessing the mounting height. Tape the outline on the wall and live with it for a day. Many households settle near kitchen-counter height for the finished top, but a wall-hung unit lets you fine-tune for tall or short users.
- Forgetting the sink changes the math. A vessel sink adds its bowl height above the counter, so the cabinet mounts lower. An integrated or undermount basin does not. Choose the sink before the mounting height.
- Confusing cabinet width with overall width. Some counters overhang the cabinet on each side. Check whether the spec dimension describes the cabinet body or the countertop.
Reading the spec sheet like a pro
Manufacturers usually list dimensions as width by depth by height, with millimetres first on Canadian and European paperwork. Look for a separate line for the countertop or basin if it differs from the cabinet, a mounting or rough-in template showing where the drain and supplies must land, and the carton weight, which matters because most wall-hung vanities ship across Canada by parcel or freight. One more Canadian note: certification marks such as CSA or cUPC apply to the plumbing components, the faucet and the drain assembly, not the cabinet itself, so do not be alarmed when the cabinet page shows none.
Once you have your measurements written down, shopping gets much easier. You can filter the wall-mount vanity collection by the widths that actually fit your wall, and pair the finished look with something from the bathroom mirror collection sized to the same width or a touch narrower. For adjacent decisions, from sinks to lighting, the rest of our buying guides cover the same fit-first approach.
Frequently asked questions
What is the most common wall-hung vanity size?
Single-sink models between 600 and 800 mm wide, roughly 24 to 32 inches, are the workhorses of the category and suit the standard Canadian bathroom. Double-sink layouts usually start around 1200 mm, or 48 inches, and a comfortable double really wants 1500 mm or more.
How high should a wall-hung vanity be mounted?
There is no single correct number, which is the appeal. Many installations put the finished counter near kitchen-counter height, but households with kids or shorter users often mount lower, and vessel sinks push the cabinet down to compensate for the bowl. Mock up the height with painter's tape before drilling.
Can a wall-hung vanity work in an older Canadian home?
Usually, yes, with preparation. Older homes often have plaster walls, irregular framing or floor-exit drains, so plan on opening the wall for blocking and possibly rerouting the trap. It is straightforward work for a contractor, but it belongs in the budget from day one.
Are wall-hung vanity dimensions metric or imperial?
Both, in practice. European brands design in millimetres and convert; North American brands often do the reverse. Measure your room in both units and compare against whichever the manufacturer treats as primary, since the converted figure is sometimes rounded.
