Wall Hung Vanity Unit Buying Guide: Sizing, Wall Fixing & What to Check Before You Buy
Share
A wall hung vanity unit, sometimes called a wall mounted vanity unit or floating vanity unit, is one of the most popular choices in modern bathroom design, and for good reason. By lifting the unit off the floor, a wall mounted vanity unit opens up the room, makes cleaning easier, and gives a bathroom a cleaner, more streamlined look than a traditional floorstanding unit. This guide covers what actually matters when choosing one, including a check most buying guides only mention in passing: making sure your wall can actually support it.
Wall Hung vs Floorstanding: Why Choose Wall Mounted
Before getting into sizing and fixing, it's worth being clear on why a wall hung vanity unit is worth choosing over a floorstanding one in the first place.
A floating vanity unit leaves the floor beneath it completely clear, which makes a bathroom feel larger and more open, particularly valuable in smaller bathrooms and ensuites. It also makes cleaning significantly easier, since there's no gap between the unit and the floor to trap dust, hair, or water. The trade-off is installation: a wall hung vanity unit needs a wall capable of properly supporting it, which is exactly what the next section covers.
If you have a larger family bathroom with no shortage of floor space, a floorstanding vanity unit remains a perfectly good option, and generally a more straightforward install. But for most modern bathroom renovations, particularly in smaller UK bathrooms, wall mounted vanity units have become the default choice.

Sizing: Width, Height and Storage Layout
Width is usually the starting point, and it's driven by both your available wall space and how much storage you actually need. Wall hung vanity units commonly range from compact 400-500mm options, ideal for cloakrooms and ensuites, up to 1200mm and beyond for double-basin units in larger family bathrooms. Measure your available wall space first, then work back from there rather than falling in love with a size that won't actually fit.
Height from the floor matters more than it might seem, and it's not simply a style choice. The standard height from the floor to the top of a wall hung vanity unit in the UK typically sits between 79-86cm, giving a comfortable working height for most adults. If your household includes notably tall or short users, or young children, it's worth considering this before installation, since a wall hung unit is more involved to reposition later than a floorstanding one.
Storage layout is the last piece: 1 or 2 drawers, or a mix of drawers and doors, depending on how you like to store things. Drawers generally suit smaller, frequently used items, while a cupboard with doors and internal shelving suits bulkier storage. Units like our Flauto range offer both drawer and door configurations depending on width, so it's worth checking exactly what storage layout comes with the specific size you're choosing rather than assuming it's the same across the whole range.

Wall Fixing: The Part Most Guides Skip
This is the section most wall hung vanity unit guides mention briefly and move past quickly, but it deserves proper attention, especially if you're choosing a unit with a heavier worktop material.
A wall hung vanity unit is only as secure as the wall it's fixed to and the fixings used to mount it. Unlike a floorstanding unit, which distributes its own weight and the weight of anything on it straight down onto the floor, a wall hung unit relies entirely on its wall fixings to carry that same load, plus the weight of the unit itself, the basin, the worktop, and everything stored inside it.
What kind of wall you have matters:
- Solid masonry walls (brick or blockwork) generally provide the strongest, most straightforward fixing, using appropriate wall plugs and screws rated for the unit's weight.
- Stud walls (timber or metal frame with plasterboard) need more care. Fixings should locate into the actual studs wherever possible, not just the plasterboard alone, which isn't strong enough to support a fully loaded vanity unit on its own. Additional noggins (horizontal timber supports) are sometimes added specifically to give a secure fixing point for a wall hung unit.
Worktop material adds to the load. A standard laminate or MDF top is relatively light, but a sintered stone top, like the one on our Flauto range, is considerably heavier due to the density of the material. This isn't a reason to avoid a stone top vanity unit, sintered stone is prized specifically for its durability and premium finish, but it does mean the wall fixing needs to be done properly and rated for the additional weight, rather than treated the same as a lighter laminate-top unit.

If you're at all unsure what kind of wall you're working with, or whether it can support a heavier stone-top unit, it's worth having a builder or fitter confirm before installation, rather than after the unit is mounted and loaded.
Basin Configuration
Wall hung vanity units typically come with one of a few basin configurations: an inset basin sitting flush within the worktop, a countertop or vessel basin sitting above it, or the worktop and basin moulded as a single sintered stone piece, as with our Flauto range. Each affects the overall look and, in the case of a countertop basin, the height of tap you'll need, worth checking against our basin mixer tap guide if you're choosing both together.

Finish and Style
Wall hung vanity units come in a wide range of finishes, from clean gloss white and warm wood tones like Country Oak, through to bolder colours for a more contemporary look. As with other bathroom fittings, it's worth matching or deliberately contrasting your vanity unit's finish with your basin mixer tap, mirror, and any other visible hardware, rather than leaving it to chance.
Our Recommendation
Our Flauto Wall Hung Vanity Unit range pairs a sintered stone top with a choice of widths and finishes, including Country Oak, one of our genuinely best-selling combinations. Given the sintered stone top, we'd particularly recommend confirming your wall type before ordering, using the guidance above.
Frequently Asked Questions
Can any wall support a wall hung vanity unit? Not without the right fixings. Solid masonry walls are generally the most straightforward. Stud walls need fixings located into the studs, or additional noggins added, particularly for heavier units with a stone worktop.
What's the standard height for a wall hung vanity unit? Typically 79-86cm from the floor to the top of the unit, though this can be adjusted slightly for household height or accessibility needs.
Is a wall hung vanity unit as sturdy as a floorstanding one? Yes, when properly fitted to a suitable wall with the correct fixings. The key is making sure the fixing method matches both the wall type and the weight of the specific unit, worktop included.
What's the difference between a wall hung and a floating vanity unit? None, these are different names for the same style of unit, mounted directly to the wall with no floor support.
