Slimline Vanities Buying Guide


A slimline vanity is a shallow vanity, built for rooms where a standard cabinet would crowd the walkway: narrow ensuites, powder rooms and hallway-style bathrooms. This collection includes slimline ranges from ADP, Timberline, Otti and Marquis, in wall hung and floor standing styles, with depths from around 250mm to 395mm.

How deep is a slimline vanity?

A standard vanity is about 450 to 500mm deep, while the slimline vanities here range from about 250mm to 395mm:

  • About 250mm: the Otti Mini Ensuite, a 400mm wide wall hung fluted vanity in matte white, Sable Walnut or Woodland Oak.
  • 340mm: the Marquis Oxford Ensuite, in 600, 750 and 900mm widths.
  • 360mm: the Timberline Florida Ensuite (600, 800 and 1000mm) and Timberline Billie (450 to 1500mm).
  • About 390 to 395mm: the ADP Mabel, Clifton, Eli and Glacier Lite Ensuite vanities.

The listed depth is usually the cabinet, and a top or basin can add a little, so check the overall depth.

Do I need a slimline vanity?

Measure the room from the wall to the opposite wall or door, then subtract the vanity depth. You need about 700 to 750mm clear in front of the vanity to stand and move. In a room 1200mm deep, a 500mm cabinet leaves 700mm, while a 390mm slimline leaves 810mm. Also keep at least 450mm from the centre of the toilet to the side of the vanity. If a standard cabinet leaves less than 700mm, choose slimline.

What do you give up with a slimline vanity?

Two things: basin size and storage. Shallow tops take smaller basins, so check that the bowl suits daily use. Less depth also means smaller drawers and cupboards. For an ensuite or powder room, that is usually workable. For a main bathroom used every morning, a 340 to 395mm depth is a better balance than the shallowest options.

Should I choose drawers or doors?

Drawers make the most of a shallow cabinet because everything is visible. The ADP Eli Ensuite and Timberline Billie are all drawers, and the Billie includes bamboo storage trays. The ADP Mabel Ensuite combines a door and a drawer, the Marquis Oxford Ensuite has an open towel shelf, and the Otti Mini Ensuite has a single soft-close door. The Florida Ensuite offers left or right hand drawers in its 800 and 1000mm sizes.

What tops and tap holes are available?

Tops include ceramic, Durasein and other solid surface materials, SilkSurface, Caesarstone and quartz. Choose the tap before ordering, as the hole is set when the top is made. The Florida Ensuite comes with one or three holes, the Glacier Lite Ensuite with none, one or three, and the Otti Mini Ensuite top can be turned to put the hole on the left or right. Some vanities don't include the plug and waste, so check what is supplied.

Wall hung or floor standing?

A wall hung vanity shows more floor, which helps a narrow room feel bigger and makes cleaning easier, but it needs noggins in the wall before it is lined. A floor standing vanity suits finished walls and hides floor plumbing. Keep any cabinet at least 300mm from a shower or bath, seal the edges with neutral cure silicone, and clean with a soft cloth and mild detergent.

Completing the room

Browse small vanities and ensuite vanities for more options, or add a mirror slightly narrower than the vanity. If no standard size fits, see custom vanities at The Blue Space.

Frequently Asked Questions

What is the narrowest vanity size?

If "narrowest" means depth rather than width, slimline vanities are built specifically to reduce that front-to-back measurement, often sitting in the low 300mm range or just under, compared with the 400 to 550mm depth of a standard vanity. If it's width you're after instead, standard ranges start around 450 to 600mm at the smallest common widths.

What are slimline vanities for bathrooms?

A slimline vanity is a cabinet built with reduced depth rather than reduced width, designed for bathrooms where the walkway or floor space in front of the vanity is tight, for example a narrow ensuite, a small powder room, or a hallway-style bathroom where a standard-depth cabinet would protrude too far into the room. Width options are generally similar to standard vanities; it's the depth that's been trimmed.

Where can I buy a narrow vanity?

For a reduced-depth unit specifically, browsing a dedicated slimline range is more reliable than searching standard vanity collections and hoping the depth happens to be smaller, since depth isn't always the headline spec on a general listing. If width rather than depth is the actual constraint, the 750mm and 800mm collections cover the narrower end of standard widths.

What is the smallest vanity depth?

Slimline models generally represent the shallow end of the market, with some sitting close to 300mm deep versus the 400 to 550mm typical of standard vanities. Going shallower than that starts to limit basin choice and usable bench depth, so it's worth checking the specific basin's own depth against the cabinet, not just the cabinet spec, since a standard-depth basin won't necessarily suit a very shallow cabinet.

Does a slimline vanity sacrifice storage compared to a standard-depth unit?

Generally yes, to some degree. Less depth means less room inside each drawer or cupboard front to back, so a slimline vanity of the same width as a standard unit will usually hold less. It's a deliberate trade-off for rooms where floor space is the limiting factor, and the loss is usually manageable for a secondary bathroom or ensuite rather than a main family bathroom with heavy storage needs.

Can a slimline vanity still be wall hung?

Yes, and the two features work well together: a slimline depth combined with a wall hung fixing keeps as much visible floor as possible in a tight room, which helps a narrow bathroom feel less enclosed. As with any wall hung vanity, it still needs solid structural blocking behind the wall to carry the cabinet safely, regardless of how shallow the unit is.
