Living Room Wall Units — Dimensions, Solutions, Ideas
A living room wall unit is a modular furniture combination typically comprising a TV lowboard, wall-hung cabinets, display cabinets, and shelving to centrally organise electronics and everyday items.
The living room cabinet forms the functional heart of the room. When choosing components for self-assembly, it is all about coordinating storage space, cable management, and the correct wall fixings. The wall unit serves as the architectural backbone of the living room – supporting technology while structuring the layout.
Dimensions and Space Planning for the Wall Unit
Planning begins with the precise measurement of the available wall space. A standard living room cabinet with plenty of storage space often requires an overall width of 250 cm - 320 cm. The depth of the base units, such as a sideboard for a television or a TV lowboard, usually measures 40 cm - 50 cm. This measurement is necessary so that AV receivers, gaming consoles, and associated cabling have sufficient room.
Wall-hung cabinets and display cabinets are built shallower, with a depth of 30 cm - 35 cm. This ensures the upper elements do not feel imposing or get in the way when walking past. A small gap should always be left between individual modules to keep the arrangement looking open.
Materials, Appearance, and Finishes
In modern furniture construction, carcases and fronts primarily consist of chipboard or MDF (medium-density fibreboard). These core materials are then melamine-coated or foiled, making them resistant to scratches and moisture.
For a modern living room wall unit, various surface finishes are available to define the character of the room:
- Wood effects: A wooden wall unit with a finish such as Artisan Oak, Wotan Oak, or Sonoma introduces a natural texture to the interior. Wood grains are often textured to the touch nowadays.
- High gloss and matt: A white high-gloss wall unit reflects ambient light, helping smaller living rooms feel larger. To avoid reflections on the TV screen, opt for matt finishes, such as a black wall unit or a grey wall unit.
- Material mix: Combining wood decors with concrete-effect accents or glass inserts for display cabinets provides an effective way to break up continuous front panels.
Assembly and Installation for DIYers
Assembling living room wall units requires a systematic approach. The carcases are generally joined using wooden dowels and an eccentric cam connector (Minifix). This type of fitting allows for sturdy assembly and subsequent, non-destructive dismantling.
Required Tools
- Cordless screwdriver with matching bits (PZ for cross-head/Pozi, often TX for Torx)
- Spirit level (at least 60 cm long)
- Impact drill or hammer drill (for wall mounting)
- Tape measure, pencil, and hammer
When assembling a multi-part TV wall unit, two people should allow around 3 to 5 hours. Flaps on wall cabinets or lowboards are frequently held open or cushioned using a gas strut. During installation, ensure the fitting provides the correct force in Newtons, as marked on the component.
Wall-Hung or Free-Standing? Solutions for the Living Room
Choosing between wall-hung and floor-standing modules affects both aesthetics and assembly effort.
Floor-Standing Systems
The entire load rests on the floor. Floor unevenness is compensated for using height-adjustable plinth feet. This variant is particularly suitable for older buildings with crumbly walls, or when storing heavy items like valve amplifiers and thick books. A matching living room chest of drawers offers additional closed storage for tableware or documents.
Floating Systems
A wall-hung unit makes floor cleaning easier and gives the room a lighter, airier feel. Mounting is achieved using concealed cabinet hangers inside the carcases. These fittings can often be adjusted by a few millimetres in height and depth via adjustment screws to achieve uniform gap dimensions.
When fixing units to the wall, wall construction is crucial. Standard nylon wall plugs are suitable for solid masonry (concrete, solid brick). For stud partitions or plasterboard, specialist cavity anchors must be used to safely bear the tensile load of the cabinets.
Frequently Asked Questions About Wall Units (FAQ)
How much clearance should be left between the TV and a wall cabinet?
Allow at least 15 cm - 20 cm of clearance above and to the sides. This gap prevents heat build-up from electronics, simplifies cable routing, and ensures the TV can be lifted off its wall bracket whenever necessary.
How do I hide cables in a wall unit?
Use lowboards with factory-cut rear cut-outs. For vertical cable routing from the lowboard to a wall-mounted TV, use a flush-mounted in-wall conduit or a colour-matched surface-mounted cable cover made of aluminium or plastic.
Which wall plugs do I need for wall-hung cabinets?
This depends entirely on the wall material. Solid walls require standard wall plugs (Ø 8 mm or 10 mm) with matching screws. For plasterboard, use metal cavity anchors that expand behind the board to prevent them pulling out under load.
