How to Choose a Bathroom Vanity

Most people choose a vanity the same way: find one that looks right, then discover what it will not do. The decisions have a natural order, and taken in that order almost nothing has to be undone. Room and services come first because they cannot move. Appearance comes last because by then it costs nothing to change.

The short answer

Quick Reference

Start with the room and the plumbing, which cannot be changed cheaply.
Decide wall-mounted or floor-standing before choosing a width.
Size to the clear floor you want to keep, not to the wall.
Choose material by how the bathroom is used, not by appearance.
Settle the basin and tap together; they constrain each other.

Decide in This Order

Every step in this list constrains the ones below it and is constrained by the ones above. Work downward and each decision narrows the field without contradicting anything already settled. Work upward, which is what browsing does, and you regularly find that the vanity you like cannot accept the basin you need at the height the room requires.

The order also matches cost. The things at the top cost the most to change after the fact. The things at the bottom cost almost nothing.

The room and the services: what cannot move
Mounting: wall-hung or floor-standing
Size: width, depth and height
Material and construction
Basin type, and the tap that goes with it
Finish, hardware and appearance

Start With What Cannot Move

Two things govern before any product is considered: the space you must keep clear, and where the plumbing is.

Mark the clear floor you intend to keep. At least 21 inches in front is a common minimum and 30 is comfortable, and any drawer needs its own full depth clear as well. Then record the waste and supply positions as horizontal and vertical distances from a fixed corner. Those numbers decide the drawer layout more than any catalog choice will.

Also settle whether the plumbing can move, and at whose cost. That single answer often decides the entire specification.

Record waste and supply positions from a fixed corner
Note the bathroom door swing, which frequently governs
Decide whether services can move, and who pays
Measure the delivery route while you are there

Wall-Mounted or Floor-Standing

This is the second decision because it changes what sizes and heights are available, and because it depends on the wall rather than on preference.

A wall-mounted vanity makes the floor continuous, which makes a small bathroom look larger and much easier to clean. It sets its own height, which is useful. But it needs a wall that can carry the loaded cabinet, and in stud construction that means noggins or a backing plate installed before the wall is closed.

A floor-standing vanity carries its load to the floor, so wall construction stops mattering. It brings a fixed height with it, it hides services more easily behind a plinth, and it needs a reasonably level floor.

Wall-mounted: continuous floor, flexible height, needs adequate wall structure
Floor-standing: no wall load, fixed height, tolerant of any wall
In renovation with unknown walls, floor-standing is the safer default
For a small bathroom, wall-mounted usually reads better
Confirm fixing method with the installer before ordering

Material and Construction

Choose by how the room is used and what finish is wanted, not by which word sounds most premium.

If the finish is painted, MDF gives the flattest result and is the correct choice, provided every edge and cut-out is sealed. If timber grain is wanted and the cabinet should last decades, solid wood in a frame-and-panel construction is the answer, because it can be refinished many times. If dimensional stability in a humid room matters most, plywood is the most stable of the three.

In practice, the best cabinets mix them deliberately: a stable plywood carcass, solid wood frames and doors, and MDF where a sprayed finish is the point.

Painted finish: MDF, with every edge sealed
Visible timber and long life: solid wood, frame and panel
Maximum stability in humidity: plywood carcass
Ask what 'solid wood' means in the specific product

Basin and Tap, Decided Together

The basin decision constrains the cabinet height, the countertop machining and the tap, so it belongs here rather than at the end.

An integrated basin removes the joint entirely, which is why projects specify it. An undermount gives a clean top surface at lower cost with the top material carrying the fixing. A drop-in is the cheapest and easiest to replace. A vessel is the most visible and raises the working height by 4 to 6 inches, so the cabinet must come down to compensate.

Whichever is chosen, the tap follows immediately: hole count, hole spacing, tap height and whether it is deck or wall mounted. All of those are drilled or roughed in before anything ships.

Integrated: no joint, best for projects and continuous runs
Undermount: clean surface, hidden sealed joint
Drop-in: cheapest, easiest to replace, visible rim
Vessel: highest impact, lower the cabinet to compensate
Fix tap holes and waste type in the same decision

Finish and Hardware, Last

By this point the field is narrow and the remaining choices are inexpensive to change, which is exactly why they come last.

Two practical notes. Lower sheen finishes hide substrate imperfections and later scratches, and in a bathroom cleaned frequently they keep a better appearance than gloss. And hardware finish is where a bathroom visibly ages: a poorly plated handle or hinge in a wet room shows within a couple of years, regardless of the cabinet quality behind it.

For project work, ask about spares at this stage too. A handle range that is discontinued in three years is a problem for a building with eighty bathrooms.

Lower sheen holds its appearance better in a wet room
Specify the hardware plating, not just the color
Soft-close runners and hinges are worth the small cost
For projects, confirm spares and continuity of the hardware range
Request a physical finish sample rather than relying on a screen

Common questions

Choosing a Vanity

What should I decide first when choosing a bathroom vanity?

The room and the services. Mark the clear floor space you want to keep and record the waste and supply positions from a fixed corner. Those constraints cannot be changed cheaply, so everything else should be chosen to fit them.

Should I choose a wall-mounted or floor-standing vanity?

Wall-mounted makes the floor continuous, suits small bathrooms and lets you set the height, but it needs a wall that can carry the load. Floor-standing works on any wall and tolerates renovation uncertainty, at a fixed height.

What size vanity should I buy?

Size to the clear floor you want to keep rather than to the wall. 36 inches is the standard single-basin width and 60 inches the standard double. Allow at least 21 inches of clear floor in front, plus full drawer depth.

What is the best material for a bathroom vanity?

It depends on the finish and the use. MDF for a painted finish with edges sealed, solid wood for visible grain and long life, plywood for maximum stability. Good cabinets often combine all three deliberately.

Do I choose the basin or the vanity first?

Together, and before the finish. The basin type constrains the cabinet height, the countertop machining and the tap, so deciding it late means revisiting decisions already made.

What is most often regretted?

Choosing by appearance first. The common outcomes are a vanity that blocks the door swing, drawers that hit the plumbing, and a vessel basin fitted at a height that nobody can use comfortably.

In short

Constraints First, Appearance Last

Room and services, then mounting, then size, then material, then basin and tap, then finish. Each step narrows the field without contradicting anything above it, and the expensive decisions get made while they are still cheap to change.

The single most useful habit is sending the room dimensions and service positions with the first enquiry. A supplier who can see them will design the drawers around the plumbing instead of leaving it for the installer to discover.

Fixed constraints govern: clear floor and service positions
Mounting before size, size before material
Basin and tap are one decision, not two
Finish and hardware last, where changes are cheap
Send measurements with the enquiry, not after the order
