Why the question keeps coming up
Timber does something no tile can. In a room of hard, cold, reflective surfaces, a timber vanity is the one warm element, and in an older house it is often the only thing stopping a new bathroom from looking like it belongs to a different building.
It is also the material most likely to fail, in the room where failure is most visible. So the useful question is not "timber or not" but "which construction of timber, and how is it detailed".
The four things sold as timber
Solid timber. Real boards, usually a hardwood or a stable timber, made into doors, drawer fronts, benchtops or a whole cabinet. It moves with humidity, it can be sanded and refinished, and the end grain drinks water if it is not sealed.
Timber veneer. A thin slice of real timber bonded to a substrate, normally MDF or particleboard. It looks like solid timber because the face is solid timber, and it is more dimensionally stable. Everything then depends on the substrate and on whether the edges are properly sealed.
Laminate. A printed and resin-impregnated surface bonded to a board, with an applied edge. Modern timber-look laminates are convincing and the face is effectively impervious. The edge is the whole story.
Melamine. A resin finish fused to the board itself. Common in cabinet carcasses and in budget-to-mid doors. Durable in the face, equally dependent on the edge.
The substrate matters more than the surface
Behind nearly every vanity door is a board. In a bathroom, which board you get is the most consequential decision nobody discusses.
Standard particleboard or standard MDF is cheap, stable while dry, and permanently destroyed by water. It swells, and swelling is irreversible; the board has physically expanded and cannot be dried back into shape.
Moisture-resistant MDF or particleboard is made for exactly this situation. It is not waterproof, but it tolerates the damp air and the occasional splash of a bathroom far better. In a mountains house, where a bathroom can be cold and humid for months, this is worth insisting on.
Marine or exterior-grade ply is more stable again and is often used for custom cabinetry. It costs more and it is a genuinely different proposition.
When a quote simply says "timber-look vanity", ask what the carcass and doors are made from. A good supplier will answer immediately.
Edges, cut-outs and the underside
Water does not attack a flat sealed surface. It attacks the places where the sealed surface stops.
The bottom edge of a door is the classic failure point, because that is the end nearest any water on the floor and the one most often left unsealed.
The basin cut-out in a benchtop is raw substrate unless it is sealed, and it sits directly under the wettest object in the room.
Tap holes are the same problem in miniature, and they get splashed every single day.
The underside of a benchtop is usually invisible and usually forgotten, which is why it is often the first thing to swell.
Applied edging on laminate and melamine: if it lifts at a corner, water gets behind it and the board is finished.
A properly made wet-area vanity is sealed on all six faces of every component, with the cut-outs sealed after they are cut, not before.
Wall-hung versus floor-standing
If you take one practical point from this page, take this one: a wall-hung vanity removes the single most common failure mode.
A floor-standing cabinet has its base sitting on a floor that gets wet. Water pools at the kick, wicks up into the base panel, and the cabinet swells from the bottom. It happens slowly and then it is obvious.
A wall-hung vanity has nothing touching the floor. It also lets the floor tile run underneath, which makes a small room look larger and makes the floor easier to clean and quicker to dry. The trade-off is that it needs proper blocking in the wall to carry the load, which is a design decision made before the walls are sheeted — see full bathroom renovations.
Finishes
Penetrating oils soak into solid timber and leave a natural look and feel. They are easy to repair — a scuff can be sanded locally and re-oiled — and they need re-coating more often.
Hard-wearing cured coatings, such as two-pack polyurethane, build a film on the surface. They resist water better day to day but they are harder to repair invisibly, because a damaged patch means recoating the whole component.
Neither choice is wrong. Choose oil if you are happy to maintain it and want to be able to fix marks yourself. Choose a cured coating if you want to think about it as little as possible.
Whatever the finish, follow the maker's instructions rather than general advice from a website — including this one.
Benchtops
Engineered stone has been banned in Australia since 1 July 2024 and is not an option. For a vanity top, the realistic choices are porcelain, natural stone, a solid-surface material, quality laminate, or sealed solid timber.
A timber benchtop in a bathroom is a commitment. It is beautiful, it is warm, and it needs the basin area detailed carefully, the cut-outs sealed, and water wiped rather than left to sit. A good compromise many people land on is timber doors and drawer fronts with a porcelain or stone top, which gives the warmth where you see it and the hard surface where the water lands.
Looking after it
- Wipe standing water off a timber top rather than letting it dry in place
- Run the exhaust fan after every shower, on a timer if possible — a vanity in a room that stays damp has a much harder life
- Check the silicone where the benchtop meets the wall once a year
- Re-coat or re-oil before the finish looks tired, not after
- Keep the inside of the cabinet dry: a slow leak at the basin tail will swell a carcass from the inside out
In a cold, damp climate, ventilation and heat do more for a timber vanity than any product. Warm, moving air is what keeps the room — and the cabinet in it — dry.
Choosing well
For most bathrooms up here the durable, good-looking answer is a wall-hung vanity, a moisture-resistant substrate, fully sealed edges and cut-outs, a hard benchtop, and timber or timber-look fronts. That combination gives the warmth people actually want without the failure mode they do not.
