Nearly every media wall problem I am called out to fix comes down to the fire being chosen after the wall was designed. It needs to be the other way round.
Most media walls I build have a fire in them, and nearly every problem I see on jobs that went wrong elsewhere comes down to the same thing: the wall was designed first and the fire was chosen afterwards. It needs to be the other way round.
The fire sets the dimensions of the opening, the clearances around it, the power supply position and often the height of everything else on the wall. If the frame is built first and the fire is chosen later, you are either stuck with whatever happens to fit or you are cutting a finished wall open.
If you have not chosen one yet, that is fine, I will help. But I will want the model confirmed before first fix, not after.
Every media wall I build takes an electric fire. There is no flue, no chimney and no combustion, so none of the regulations that come with a real flame apply. It plugs into a standard supply and it can go into a stud wall in a flat as easily as a house.
That still leaves plenty to choose between. Inset units sit flush in a single opening. Panoramic ones are visible from two or three sides and need the recess built differently. Water vapour fires produce a convincing mist flame and need a fill point you can actually reach. Widths range from around half a metre to well over two, and that measurement drives the proportions of everything else on the wall.
Worth saying plainly. An electric media wall fire is a feature, not a heating system. Most are around two kilowatts on full heat, which will take the edge off a room but will not replace your radiators. Anyone telling you otherwise is selling something.
Every fire comes with manufacturer clearances: how much space must be left above it, how far back the recess can go, what materials can sit next to it and whether the unit needs air around it. Those figures are not advisory. They are the difference between a wall that is safe and a wall that discolours, warps or worse.
This is where cheap installs cut corners, because the clearances are invisible once the wall is plastered. Nobody can see what is behind the board. I build to the manufacturer spec and I keep the paperwork.
It is the most requested layout and it is perfectly doable, but two things matter.
First, heat. There must be enough separation, and ideally a mantel shelf or a deflector, so rising warm air is not running straight up the back of your screen. The fire manufacturer will state a minimum distance and the TV manufacturer will state a maximum operating temperature. Both have to be respected.
Second, viewing height. A TV stacked above a fire often ends up higher than is comfortable for a sofa two or three metres away. If you are watching it every evening, that angle matters more than people expect. Sometimes the better answer is a wider wall with the fire offset rather than a tall stack.
The fire needs its own supply, positioned where it can be reached if it ever needs isolating. Most modern units are remote controlled, some have app control, and a few need a switched spur in a sensible place. All of that is decided at first fix while the frame is still open.
Paint is the most common and the easiest to touch up. Microcement and textured plaster look superb and are increasingly asked for, but they need the right substrate and more drying time. Stone and tile cladding around a fire is possible but adds weight, which means the frame has to be built for it from the start, not reinforced later.
A fire makes a media wall. It is the thing that turns a TV recess into the part of the room people actually sit around. But it is also the component with real safety rules attached, and it is the one I will not let a client talk me into rushing.
