How to Choose the Right TV Wall Unit for Your Lounge

A TV wall unit is one of those things that sounds simple until you start thinking about it properly. The TV needs to sit at the right height. The cables need to go somewhere. The decoder, soundbar, and router all need a home. The proportions need to make sense for the wall. And it needs to look like it was planned, not assembled piece by piece over the years.

We've built TV walls in homes across KwaZulu-Natal long enough to know what questions homeowners should be asking — and what gets left out of the conversation until it's too late. Here's what to think through before you commit to a design.

1. Get the height right first

The single most common mistake with TV installations is mounting the TV too high. It feels counterintuitive — higher seems safer, more visible. But the rule is simple: the centre of the screen should be at eye level when you're seated.

For a standard couch height, that's usually around 100–110cm from the floor. Measure where you sit, hold your hand at eye level, and that's approximately where the centre of your screen should be.

If you're building a wall unit that runs from floor to ceiling, the shelf or housing for the TV needs to be positioned based on your seating height, not based on what looks symmetrical on the wall.

We always discuss this on-site. Sometimes the ideal TV height conflicts with what would look good from the other side of the room. We find the balance.

2. Decide on the full footprint

A TV wall unit can be just a floating shelf with a TV on it. It can be a full floor-to-ceiling system with display niches, storage drawers, and backlit panels. Or anything in between.

Think about what you actually need to store:

• Decoder and cables
• Soundbar or speaker setup
• Gaming consoles
• WiFi router
• Books, ornaments, display items
• DVDs (if you still have them)

More importantly, think about what you don't want to see. A good TV wall hides everything ugly and shows only what you want displayed. Plan the storage around your actual equipment, not a hypothetical ideal setup.

3. Think about the room size, not the TV size

A common mistake is sizing the unit based on the TV instead of based on the wall.

A 65-inch TV on a narrow floating shelf on a wide wall looks unfinished. The same TV mounted in a floor-to-ceiling unit that fills the wall looks intentional.

We generally recommend that the wall unit extends at least two thirds of the wall width. For a large feature wall, floor-to-ceiling units with storage on both sides of the TV look the best and make the most efficient use of the space.

4. LED backlighting — yes or no?

LED backlighting behind a TV wall unit does two things. First, it looks good — a soft warm glow around the back of a floating shelf or panel adds depth and makes the whole unit feel more premium.

Second, it reduces eye strain. The contrast between a bright screen and a dark wall behind it is hard on your eyes, especially at night. A backlit panel behind the TV softens that contrast.

We build the LED strips into the unit as standard when clients want them. They run off a low-voltage driver and use very little electricity. A simple single-colour strip is the most popular choice. RGB (colour-changing) is available but tends to end up set to amber and left there.

5. Cable management from day one

Cable management is not something you add later. It needs to be planned into the build from the start.

Specifically:

• Where does the TV's power cable run?
• How does the HDMI cable from the decoder get to the TV?
• Where does the WiFi router sit, and where does its cable enter the unit?
• Is there a soundbar, and how does it connect?

We build cable channels into every unit we make. All the technology housing is hidden. Only the TV and any display items are visible. That's the point.

If you need a new power point added to the wall, we can coordinate an electrician to do that before we build the unit.

6. The finish matters

The material and finish of your wall unit should relate to the rest of the room. It doesn't need to match your existing furniture exactly, but it shouldn't fight with it either.

Popular choices for KZN homes:

• Matte white or light grey — clean, works in most rooms
• Charcoal or dark grey — dramatic, especially good as a feature wall
• Wood grain (melamine) — warm, suits homes with timber accents
• Two-tone (e.g. white main unit, dark insert behind TV) — current, looks considered

We can work from a finish sample you bring in, or advise based on photos of your existing room.
