Slim Bathroom Cabinets
Maximise tight spaces with our slim bathroom cabinets and slimline vanity units. Explicitly designed for narrow layouts and compact cloakrooms, these ultra-slim bathroom storage solutions measure just 200mm-300mm in depth whilst delivering essential organisation. Perfect for squeezing storage into awkward corners, between fixtures, or along narrow walls where standard-depth units simply won't fit.
What is a slim bathroom cabinet?
A slim bathroom cabinet, also known as a slimline vanity unit, features reduced depth, typically 200mm-300mm, compared to standard 400mm-500mm furniture. This narrow profile allows the unit to fit into tight spaces where conventional cabinets would protrude excessively, creating circulation problems or simply not fitting at all.
Dimensions of narrow bathroom cabinets
Our slim bathroom furniture features carefully considered proportions:
-
Width: 400mm provides adequate basin size for comfortable handwashing whilst maintaining a compact overall footprint.
-
Depth: 200mm-300mm creates the defining slimline profile that allows installation in narrow spaces where standard cabinets won't fit.
-
Height: Floor-standing models typically reach 800mm-900mm, including basin, providing standard countertop working height. Wall-hung versions measure 400mm-500mm, installed at a comfortable basin height.
These dimensions create functional bathroom facilities in spaces measuring just 800mm-1000mm wide, where standard-depth furniture would create unacceptable circulation problems. For more compact bathroom solutions, explore our small bathroom vanity units.
Where do slim bathroom storage units work best?
Our slim vanity units excel in space-constrained environments:
-
Narrow Cloakrooms: Downstairs toilets often measure just 800mm-1200mm wide, where standard-depth furniture creates cramped conditions. Cloakroom vanity units leave adequate circulation space whilst providing necessary facilities.
-
Corridor Bathrooms: Long, narrow bathrooms benefit from reduced-depth furniture that doesn't obstruct the central walkway. Installing slimline vanity units along one wall maintains a comfortable passage whilst delivering storage.
-
En-Suite Bathrooms: Compact en-suites converted from bedroom corners or boxed-in spaces often have awkward dimensions. Thin bathroom cabinets fit into tight alcoves between doorways and shower enclosures.
-
Between Fixtures: Narrow gaps between existing toilets and walls, or spaces beside shower enclosures, accommodate slim vanity units with a basin where standard units wouldn't physically fit.

Storage in slimline bathroom cabinets
Despite their narrow bathroom storage profile, these slim vanity units with basins provide practical organisation. Single door cabinets feature internal shelving that utilises the full 200mm-300mm depth. The narrow profile actually works well for bathroom essentials like hand soap bottles, toothbrush holders, and cleaning supplies that don't require deep storage.
Internal shelves can be repositioned to accommodate items of varying heights, from tall bottles to folded hand towels. The slimline depth prevents items from getting lost at the back, making everything easily accessible.
Thin bathroom cabinet finishes and styles
Our ultra slim bathroom storage range features contemporary finishes designed to enhance compact spaces:
-
Gloss White Slim Cabinet: Bright, reflective surfaces bounce light around tight cloakrooms, making narrow spaces feel larger.
-
Indigo Grey Gloss Slim Cabinet: Sophisticated grey with reflective finish offers modern depth whilst maintaining light-reflecting properties that benefit compact layouts.
-
Hale Black Slim Cabinet: The dark finish adds unexpected sophistication to compact cloakrooms.

Basin options for slim bathroom cabinets
Slim bathroom cabinets feature compact ceramic basins specifically proportioned for narrow installations. Choose between integrated slim basins or white ceramic constructions. A slim vanity unit with an integrated basin maximises usable bowl depth within the reduced unit depth. A white, slim vanity unit with a basin material offers easy cleaning and long-term durability. The white gloss finish complements all cabinet colours whilst maintaining a fresh, hygienic appearance.
Browse our cloakroom basins for additional compact basin options.
Slim bathroom furniture mounting options
Choose between two installation styles for your narrow bathroom cabinet:
-
Wall Mounted Slim Cabinet: Creates a floating aesthetic that maximises visual and physical floor space. The suspended design makes floor cleaning effortless whilst contributing to contemporary styling. This mounting style works particularly well in ultra-slim bathroom storage applications where every centimetre counts.
-
Floor Standing Slim Cabinet: Offers traditional styling with straightforward installation. The grounded design provides slightly more internal storage volume and works well where wall mounting proves impractical due to wall construction or existing pipework.
Explore our wall hung vanity units and floor standing vanity units for more options and sizes.
Installing slimline bathroom storage
For wall-hung slim vanity units, measure and mark the mounting height carefully, ensuring the basin sits at a comfortable level. Secure mounting brackets into solid walls or reinforced stud work. Connect waste pipework before final positioning.
For freestanding slim vanity units, position the model so that the plumbing connections align with the basin waste. Check that the unit sits level using a spirit level. Secure to the wall with the provided fixings for stability. The narrow depth means units should always be wall-secured to prevent tipping.
Please note that in very narrow installations, you should carefully consider plumbing access. The reduced depth may require creative pipework routing to avoid conflicts with wall studs or existing services. For comprehensive guidance, consult our installation guide for bathroom cabinets or our vanity unit installation guide.
