Walk into any bathroom showroom in Montreal and you will be met with rows of beautiful vanities, gleaming mirrors, and floating cabinets that look absolutely perfect under careful lighting. Then you bring one home, realize it does not fit your wall, the finish starts bubbling after two winters, and a drawer hinge fails eight months in.
This happens more often than contractors like to admit. And it almost always comes down to one thing: choosing bathroom cabinets the same way you would choose kitchen furniture, without accounting for the unique demands of a bathroom environment.
This guide is for Montreal homeowners who want to get it right the first time. Whether you are refreshing a tired ensuite in a Plateau triplex, building out a spa bathroom in a Laval bungalow, or simply replacing a vanity that has seen better days, here is what actually matters.
Why Bathrooms Are Harder on Cabinets Than Any Other Room
Think about what your bathroom goes through on any given morning. Hot showers send humidity levels well above 70 percent. Cold winters dry the air dramatically. Cleaning products splash onto cabinet surfaces. Doors are opened and closed dozens of times a day. Pipes run behind and beneath cabinets, occasionally leaking.
Most furniture, even high-quality bedroom and living room furniture, is not built to handle this combination. Standard MDF swells when moisture penetrates it. Particleboard, which is common in budget cabinet boxes, can absorb so much moisture that hinges literally pull out of the material within a few years. Certain finishes that look beautiful in a showroom start to peel, bubble, or yellow when exposed to repeated steam cycles.
In Montreal specifically, the problem is compounded by our climate. Hot, humid summers followed by months of dry, forced-air heating create seasonal expansion and contraction cycles that stress every joint and finish. A cabinet that performs adequately in a more temperate climate can fail noticeably faster here.
| The single most important question to ask before buying any bathroom cabinet is not whether it looks good. It is what the box is made of. The door is cosmetic. The box is structural. |
Moisture-resistant MDF, properly sealed, performs well in most Montreal bathrooms. Marine-grade plywood is the premium choice and genuinely worth the price in high-humidity bathrooms or below-sink installations where pipe condensation is a concern. Solid wood works beautifully when properly finished with a moisture-resistant sealant, though it requires more maintenance over time. What you want to avoid at any price point is standard particleboard or untreated MDF in the box construction, and these are often the exact materials used in budget cabinet lines.
The Types of Bathroom Cabinets and What Each One Actually Does
Before jumping into costs and decisions, it helps to understand what each cabinet type is genuinely good for. Not in a theoretical sense, but in the context of real Montreal bathrooms.
Vanity Cabinets
The vanity is the anchor of almost every bathroom renovation. It sits beneath the sink, provides the bulk of accessible storage, and sets the visual tone for the entire space. In Montreal’s older housing stock, particularly in Plateau, Rosemont, and Mile End triplexes, the available wall space for a vanity is often limited, which makes precise sizing and custom builds far more practical than off-the-shelf options.
Vanity cabinets come in freestanding and wall-mounted floating versions. A floating vanity creates the illusion of more floor space, genuinely useful in bathrooms under 50 square feet, but requires proper wall anchoring and adds complexity to the plumbing rough-in. In a bathroom where every inch matters, this trade-off is almost always worth making.
Wall-Mounted Cabinets
These are the storage units mounted above the toilet, above the door, or alongside the vanity mirror. Often underestimated, they can nearly double the storage capacity of a small bathroom without touching the floor plan. For Montreal apartments and condos where square footage is tight, well-placed wall-mounted cabinets make an enormous practical difference.
Medicine Cabinets
Recessed or surface-mounted, medicine cabinets with mirrored fronts serve double duty. They provide storage for medications, grooming items, and the small everyday essentials that clutter bathroom countertops, while also functioning as the primary mirror. In bathrooms too small for a separate mirror and storage unit, they are often the smartest single purchase you can make.
Tall Storage Towers
Floor-to-ceiling storage towers make sense in family bathrooms where the demand for towels, linens, cleaning products, and toiletries genuinely requires vertical space. A well-designed 18-inch deep tower can hold an impressive amount without eating into the floor area. They are particularly effective flanking a freestanding bathtub in larger NDG or Laval bathrooms.
Custom Full-Wall Units
When storage is a serious priority and the bathroom has the square footage to support it, a custom full-wall cabinet unit integrating the vanity, wall cabinets, and mirror into a single designed piece creates a result that simply looks different from anything you can buy ready-made. This is the option we recommend for master bathroom renovations in Westmount, Outremont, and upscale South Shore projects.

What Custom Bathroom Cabinets Cost in Montreal in 2026
Let us talk real numbers. One of the most frustrating experiences for Montreal homeowners is receiving a renovation quote that bears no relation to what they budgeted based on online research. Part of the problem is that most cost guides do not account for the Montreal contractor market, the specific housing types in each borough, or the actual labour complexity involved.
Here is a realistic breakdown of what bathroom cabinet projects cost across Greater Montreal in 2026:
| Project Type | Typical Range (CAD) | What Is Included | Timeline |
| Vanity replacement only | $1,800 to $5,500 | Vanity, countertop, faucet, basic plumbing | 1 to 2 days |
| Vanity, wall cabinet, medicine cabinet | $3,500 to $9,000 | All three units, installation, hardware | 2 to 3 days |
| Full custom bathroom storage system | $7,000 to $18,000 | Custom-built all units, coordinated design | 3 to 6 days on site |
| Full bathroom renovation with tile | $18,000 to $45,000 plus | Everything including cabinets, tile, plumbing, fixtures | 1 to 3 weeks |
These ranges assume quality materials and licensed installation. The lower end of each range reflects smaller bathrooms with simpler finishes. The upper end reflects larger bathrooms, premium materials like quartz countertops and solid wood, and any plumbing coordination required.
| A Note on Older Montreal Homes Plateau, Rosemont, and Mile End triplexes frequently have non-standard bathroom dimensions: walls out of square, floors slightly uneven, plumbing in unexpected locations. These conditions almost always make custom-built or precisely measured semi-custom cabinets more practical than off-the-shelf units. Budget an additional 10 to 15 percent for older buildings to account for site-specific adjustments. |
What Bathroom Renovations Look Like Across Montreal Neighbourhoods
Plateau-Mont-Royal, Rosemont and Mile End
These are Montreal’s classic triplex neighbourhoods, and the bathrooms reflect the architecture: generally compact, often 35 to 55 square feet, with lower ceilings and plumbing layouts that have sometimes been modified across multiple renovation generations. The challenge is not finding storage solutions that look good. It is finding ones that physically fit and work with what is already behind the walls.
Floating vanities in the 24 to 36 inch range dominate here, paired with recessed or surface-mounted medicine cabinets. The aesthetic tends toward clean and modern: matte finishes, minimal hardware, light colours that make the space feel larger. Budget for unexpected plumbing discoveries, because they are more common than not in buildings over 60 years old. Typical bathroom cabinet budget for this area: $3,500 to $9,500 installed.
NDG, Westmount and Cote-des-Neiges
Semi-detached and detached homes in NDG and Westmount typically offer larger bathrooms, 60 to 100 square feet, that give more design latitude. Many of these homes have bathrooms that were last renovated in the 1980s or 1990s, and the jump from dated oak cabinetry with brass hardware to a contemporary custom vanity is one of the highest-impact transformations available for the investment. Transitional style is dominant here: shaker-profile doors, quartz countertops in white or grey, brushed nickel or matte black hardware. Budget: $6,000 to $16,000 depending on scope.
Laval (Chomedey, Vimont, Sainte-Rose, Duvernay)
Laval’s post-1970 bungalow stock has generally better-maintained infrastructure and larger bathroom footprints than Montreal’s older boroughs. Full bathroom renovations, new cabinets, new tile, updated plumbing, are the most common project type here. Spa-inspired aesthetics are popular: warm wood-tone cabinet finishes, integrated LED mirrors, walk-in showers with tiled benches, and freestanding bathtubs in larger master suites. Budget: $8,000 to $22,000 for the cabinet scope.
South Shore (Brossard, Saint-Lambert, Longueuil, Boucherville)
The South Shore consistently represents the upper range of bathroom renovation investment in Greater Montreal. Master bathrooms here are frequently 100 square feet or more, and the expectation is a finished result that matches the quality of the home. Custom full-wall vanity units, book-matched panels, integrated sinks, and premium stone countertops are common requests. Budget: $12,000 to $30,000 or more for the cabinet scope.
Five Things That Go Wrong and How to Avoid Them
1. Buying before measuring
It sounds obvious, and yet it is the most common mistake. Ordering a 48-inch vanity for a wall space that measures 47.5 inches means returning a large, heavy cabinet or grinding down a wall. In older Montreal homes where walls are rarely perfectly square, room-scale measurements taken from corner to corner are not sufficient. You need precise measurements at multiple heights, accounting for baseboard trim, pipe locations, and door swing clearances.
2. Prioritizing looks over moisture resistance
A beautifully photographed bathroom with open wood shelving and a whitewashed oak vanity is inspiring. But in a bathroom used by a family of four with teenagers taking long showers, unsealed wood surfaces and open shelving accumulate moisture damage and clutter within months. Beautiful and functional are not mutually exclusive, but functional has to come first in the design brief.
3. Skipping proper ventilation before installing new cabinets
No matter how good your materials are, a bathroom with inadequate ventilation will shorten cabinet lifespan significantly. Before investing in new cabinetry, make sure your bathroom exhaust fan is properly rated for the room’s cubic volume and actually vented to the exterior. Many older Montreal homes have fans that technically work but exhaust into the wrong space. Fixing this before the cabinet installation protects your investment for the long term.
4. Coordinating plumbing as an afterthought
A vanity installation always involves plumbing. Connecting a new sink to existing drain and supply lines is straightforward in a well-maintained bathroom. It becomes complicated and expensive when pipes are in poor condition, the new vanity’s drain does not align with the existing rough-in, or the water supply shutoffs have not worked in fifteen years. Identify these issues at the planning stage, not after the old vanity is demolished.
5. Hiring unlicensed labour for below-the-sink work
In Quebec, plumbing work including connecting drain lines and supply valves must be coordinated with a licensed master plumber. An unlicensed contractor who handles plumbing connections can void your home insurance and create legal liability if water damage occurs. Always ask whether your contractor works with licensed plumbing trades. Tross Construction holds RBQ License #5841923501 and works only with appropriately licensed tradespeople for all regulated work.
Your Questions Answered
What is the most durable countertop material for a Montreal bathroom?
Quartz is the best all-around choice for most Montreal bathrooms. It is non-porous, so it does not absorb water, stains, or bacteria, and requires zero sealing. Porcelain slab is an excellent alternative and is extremely heat and scratch resistant. Marble looks stunning but is porous, stains easily, and requires annual sealing. It is best reserved for lower-traffic powder rooms where you can genuinely maintain it. Laminate is budget-friendly and underrated for secondary bathrooms: modern laminate handles moisture well and comes in very convincing stone looks.
Can I keep my existing tile and just replace the cabinets?
In most cases yes, and this approach often makes excellent financial sense. Replacing only the vanity, wall cabinets, mirror, and faucet while keeping existing tile can dramatically refresh a bathroom at a fraction of the full renovation cost. The main consideration is whether the new cabinet dimensions align cleanly with the existing tile lines. We design new cabinet layouts around your existing tile during the consultation so there are no awkward offcuts or exposed raw tile edges.
How long does a bathroom cabinet installation take?
A vanity-only replacement typically takes one day. Adding wall cabinets and a medicine cabinet brings it to two days. A full custom bathroom storage system with fabrication runs 3 to 5 days on site, plus 2 to 4 weeks fabrication lead time before we arrive. We give you a precise schedule at the quote stage so you can plan accordingly.
Is a floating vanity structurally sound enough for daily use?
Yes, when properly installed. A floating vanity mounted into wall studs, or into a properly anchored wall plate if studs are not in the right position, will support the weight of the countertop, sink, and normal cabinet contents without issue. What makes people nervous about floating vanities is usually inadequate installation, not the design itself. Our installers anchor all floating units into structural framing and test for load before leaving.
Do you serve NDG, Laval, and the South Shore for bathroom renovations?
