Bathroom Cabinets in the Kitchen: Dimensions, Solutions, Ideas
A classic bathroom cabinet features a shallow carcass depth of 15 cm to 30 cm, making it an ideal problem-solver for narrow recesses in the kitchen.
Standard kitchen runs are standardised to a depth of 60 cm. In older properties, awkward floor plans, or after positioning large domestic appliances, narrow gaps often remain where no standard kitchen unit will fit. In these scenarios, experienced DIYers turn to units designed for bathrooms. Thanks to their compact dimensions, they offer the opportunity to transform unused space into valuable storage.
Dimensions and Space Planning: When Standard Kitchen Units Do Not Fit
The deciding factor when repurposing a bathroom cabinet is its dimensions. Whilst traditional kitchen base units take up considerable depth, bathroom furniture is engineered for tight spaces.
Frequently required dimensions for kitchen alcoves are:
- Depth: 15 cm, 20 cm, or 25 cm
- Width: 20 cm to 30 cm
- Height: Variable, from 80 cm (base unit level) up to 190 cm (tall larder unit)
A bathroom cabinet that is 15 cm or 20 cm deep will not sit flush with a 60 cm deep kitchen worktop. Instead, it is placed further back against the wall or used as a freestanding, standalone piece. A slim cabinet acts like a tailor-made gap filler in spatial Tetris, fitting precisely where a conventional solution fails – such as between the fridge and the wall, or next to a radiator.
If you have a deeper recess and want to utilise it fully, you can build a slim carcass yourself instead of using a pre-made bathroom unit and equip it with suitable fittings. Special kitchen cabinet pull-outs with a 15 cm width or a kitchen cabinet pull-out with a 20 cm width are ideal for making provisions accessible right into the back corners. For slightly wider gaps, a kitchen cabinet pull-out with a 30 cm width is a great option.
Material Choice: Does Bathroom Furniture Withstand the Kitchen Environment?
The climatic conditions in kitchens and bathrooms are remarkably similar. Both rooms experience moisture, steam, and temperature fluctuations. Bathroom furniture is factory-designed to withstand these demands.
- Carcass: Usually made from chipboard with a hard-wearing melamine resin coating. This seals the timber core, making the surface wipeable and resistant to grease splatters.
- Fronts: Frequently made from MDF (medium-density fibreboard) that is lacquered or foil-wrapped.
- Solid wood: A bathroom cabinet made of timber (e.g. oak or bamboo) adds warmth to the kitchen. However, the wood must be oiled or varnished to prevent cooking fumes from penetrating.
To ensure the repurposed cabinet blends visually into the existing kitchen run, changing the handles is recommended. Replacing the factory-fitted hardware with matching kitchen furniture handles creates a cohesive overall look. Colour choice is also important: a slim bathroom cabinet in anthracite or a wood finish can easily be combined with contemporary kitchen fronts.
Clever Solutions for Internal Storage
A very shallow cabinet (e.g. 15 cm deep) is superb for items that often get lost in deep cupboards. Because items sit in a single row, you have immediate access.
Typical uses for narrow cupboards include:
- Spice rack: Jars and tins fit perfectly into a depth of 15 cm.
- Cleaning cupboard: Bottles, sponges, and dishwasher tablets can be stored in the lower section next to the sink.
- Bottle store: Vinegar, oil, and drinks bottles find plenty of standing room in a 25 cm deep unit.
If the chosen unit features drawers, the organisation can be enhanced further with a kitchen drawer organiser.
Kitchen planning tip: Whilst the slim bathroom unit fills the narrow gap, the main waste management system should remain integrated within the standard 60 cm deep base unit. Systems such as a kitchen recycling bin or a compact pull-out waste bin for 40 cm cabinets are well suited for this purpose.
Assembly: Building and Secure Wall Anchoring
Assembling a flat-pack bathroom unit for the kitchen requires basic tools and typically takes 45 to 60 minutes.
Required tools:
- Cordless screwdriver (with PZ2 or TX bits)
- Spirit level
- Folding rule or tape measure
- Drill (for wall fixings)
Crucial assembly step: Anti-tip safety Furniture with a small footprint (e.g. 25 cm wide and 20 cm deep) has a strong tendency to tip forward when the door is opened. This applies particularly to tall units. Anchoring the cabinet to the wall is essential. Use the supplied corner brackets along with suitable wall plugs and screws matched to your wall construction (e.g. hollow wall anchors for plasterboard). Align the carcass precisely with a spirit level before fixing to ensure the doors do not rub or catch later on.
Frequently Asked Questions (FAQ)
How deep should a cabinet be for narrow kitchen gaps?
Cabinets with a depth of 15 cm to 25 cm are ideal for typical kitchen recesses. Measure the distance from the rear wall to the front edge of the adjoining units carefully, making sure to account for any protruding skirting boards or pipework.
Can I place a wooden bathroom cabinet in the kitchen?
Yes, provided the material is protected against moisture. Lacquered solid wood or chipboard with a melamine resin coating are perfectly suitable. Untreated timber should be oiled or sealed with a clear varnish before kitchen use to prevent water and grease stains.
How do I adjust the shelves in a narrow cabinet?
Most cabinets feature pre-drilled system holes using System 32 (32 mm hole spacing). Standard shelf supports (typically 3 mm or 5 mm in diameter) allow you to flexibly adjust the shelf height to accommodate tall bottles or small spice jars.
