Bathroom Highboard: Dimensions, Solutions, and Ideas

A highboard in the bathroom combines vertical storage space with a compact footprint to keep towels and care products neatly organised within reach at a typical height of 100 cm to 130 cm.

Particularly in functional rooms where available floor space is often restricted by sanitary installations and radiators, this type of furniture proves to be an efficient problem-solver. It neatly bridges the gap between a low base unit and a full-height tall cabinet. The top shelf surface is ideal for everyday items, whilst the carcass conceals the primary storage space.

Dimensions and Proportions for the Bathroom

The dimensions determine whether the unit blends harmoniously into the space or obstructs walkways. In the bathroom, different spatial rules apply compared to the living area.

• Depth: A carcass depth of 30 cm to 35 cm has established itself as standard in the bathroom. With a depth of 30 cm, open doors or drawers do not extend too far into the room, which is particularly important in narrow, galley-style bathrooms. Conversely, a depth of 35 cm provides precisely the room required to store rolled bath towels sideways.
• Width: A narrow highboard with a width of 50 cm frequently fits neatly into alcoves, for instance between the washbasin and the shower. For family bathrooms requiring more space, widths of 70 cm or 75 cm are well-suited. If an entirely open wall is available, a model with a width of 110 cm can also be installed, which visually resembles a closed chest of drawers.
• Height: At a height of 100 cm to 130 cm, the top cover panel remains conveniently within reach.

Those storing towels or bathrobes in very large quantities often hit capacity limits in the bathroom and turn to a wardrobe for 2 people in the bedroom. However, for everyday essentials in moisture-prone rooms, the highboard remains the more compact choice.

Material Choice: Moisture Protection is Essential

Bathrooms are wet rooms. Steam from showering and direct water splashes place significant demands on materials. Untreated solid wood works considerably under these conditions, swelling or warping.

For self-assembly, engineered wood materials such as chipboard or MDF (medium-density fibreboard) dominate. The surface treatment is crucial for durability. An intact melamine coating acts like a raincoat for the wood core, allowing water droplets to simply pearl off. Equally important is edge banding. An impact-resistant ABS edge made of plastic seals the cut edges of the panels so that no moisture can penetrate inside.

Aesthetics and Finishes: From Wotan Oak to Matt Black

The design of the front panels sets the atmosphere of the room. Because bathrooms often appear cool due to tiles and ceramic, wood decors are highly sought after. A Wotan oak or Sonoma oak decor brings visual warmth into the room without requiring the intensive maintenance of real wood.

For modern, minimalist interior concepts, a highboard in black is an ideal choice. Matt, dark finishes create a striking contrast against white washbasins and chrome-plated taps. In general, highboards in the bathroom offer a strongly function-driven appearance. Whilst a sideboard for TV or a lowboard for TV in the living room is often wider and lower to accommodate electronics, the bathroom highboard focuses on vertical compartment division.

Fittings and Mechanism in Detail

A piece of furniture is only as good as the hardware that holds it together and moves it. DIY enthusiasts should pay attention to the following mechanical components during assembly:

• Hinges: Doors are generally attached using a concealed cup hinge. The standard drilling diameter for the hinge cup is 35 mm. An opening angle of 110° is usually completely sufficient for bathroom furniture. An integrated damper ensures that the door closes gently (soft-close), which is especially advantageous during early mornings in reverberant bathrooms.
• Drawer runners: For cosmetics drawers, a ball-bearing runner or undermount runner is recommended. The extension type is important here: a full extension runner pulls out to 100%, ensuring that even small tubs in the rearmost corner are easily accessible. A partial extension runner stops at around 75% of its length.
• Flap fittings: If the unit features a laundry flap in the upper section, gas struts for heavy flaps are frequently used. The force of these cylinders is specified in Newtons (N) and must be matched precisely to the weight of the MDF or chipboard front so that the flap remains safely open.

Assembly and Installation: Tips for DIYers

Assembling a bathroom highboard takes between one and two hours for experienced DIY enthusiasts. Assembly is typically carried out lying flat on the floor before the carcass is raised into position.

Required Tools

• Cordless screwdriver with matching bits (usually PZ for Pozi or TX for Torx)
• Spirit level and folding rule
• Wooden mallet (for gently driving in wooden dowels)
• Drill and masonry bit (for wall fixings)

Step-by-Step Procedure

1. Preparation: Sort all cam and pin connectors, wooden dowels, and screws. Inspect the panels for any transit damage.
2. Carcass assembly: Connect the side panels to the base and top panels. Use the wooden mallet lightly to avoid driving the dowels through the surface coating.
3. Securing the back panel: The back panel is usually nailed or slid into a groove. It is strictly necessary, as it provides the carcass with diagonal stability.
4. Fitting hardware: Screw the mounting plates for the hinges and the runners for the drawers into the marked pre-drilled holes in the System 32 grid (32 mm hole spacing).
5. Wall mounting: Every highboard must be securely anchored to the wall to prevent tipping. When heavy drawers are pulled out, the centre of gravity shifts drastically forward. Use wall plugs suitable for your specific wall structure.
6. Alignment: Adjust the unit to be perfectly level using adjustable furniture legs. Afterwards, hook in the doors and drawers and adjust them to millimetre precision using the adjustment screws on the hinges.

Frequently Asked Questions (FAQ)

What depth is ideal for a bathroom highboard? For most bathrooms, a depth of 30 cm to 35 cm is ideal. These dimensions provide ample space for folded towels and grooming products without visually overpowering the room or restricting movement in front of the basin.

Which material is suitable for damp rooms? Engineered wood materials such as chipboard or MDF panels sealed with a high-grade melamine coating are most suitable. Clean edge banding (e.g. ABS edges) is also essential to prevent moisture from penetrating the wood core and causing it to swell.

Does a highboard in the bathroom need to be fixed to the wall? Yes. Due to its structural height and shallow depth, a highboard has a relatively high centre of gravity. As soon as loaded drawers or doors are opened, there is a risk of tipping. Fixing it firmly to the wall is indispensable for safety.

How do I care for matt black surfaces in the bathroom? Clean matt finishes best using a soft, lint-free microfibre cloth and lukewarm water. For minor limescale or soap residues, a mild all-purpose cleaner helps. Avoid abrasive sponges, as they can scratch the melamine coating.
