The Appliance Clearance Mistake That Doesn't Show Up Until the Fridge Arrives

Here's the assumption that gets almost every fitter at some point: if the appliance fits the cutout on the spec sheet, it'll fit in the kitchen. The box goes in, the panel goes on, job done.

It's wrong. Not because the cutout size is wrong. Because a cutout is a static number, and a door is not. A fridge door, a dishwasher door, an oven door — they all swing through space. The spec sheet tells you the appliance fits the hole. It says nothing about what happens when the door moves.

That gap between "fits the hole" and "actually works in the room" is where most clearance problems live. And they usually don't show up on site day one. They show up weeks later, when the appliances arrive and the kitchen's already been fitted around them.

It's not just fridges either. Ovens built into a tall housing need a ventilation gap above and below, and that gap gets eaten up fast if the carcass above it was built tight to save a few millimetres. A built-under microwave needs clearance for its own door swing too, and that door often opens wider than people expect because it has to clear the control panel.

Every one of these has a number on a data sheet somewhere. The problem isn't that the information doesn't exist. It's that nobody goes looking for it until something doesn't open the way it should.

• The fridge door stops dead at 90 degrees instead of swinging past it
• A dishwasher door, once open, blocks the drawer front right next to it
• Two handles on neighbouring appliances knock into each other when both doors are open
• A integrated door panel sits slightly off the cabinet face and catches on the hinge when it swings
• The salad drawer or crisper won't pull out because the door can't open far enough to clear it
• A fridge tucked at the end of a run can't open past the wall it's hard against
• The toe kick or filler panel doesn't line up once the real appliance panel goes on, because it's thicker or thinner than what was planned for

Picture a tall integrated fridge freezer, pushed right up against an end wall to save floor space. Looks tidy on the plan. Then the appliance turns up, the door's hinged on the wall side, and it only opens as far as the wall lets it — nowhere near the 100 to 115 degrees most fridges need for full access to the shelves inside.

Now the client can't get the crisper drawer out. That's not a small snag. That's a kitchen that doesn't work the way it was sold. And it's not something you can plane down or pack out with a shim. The wall is the wall. The hinge is fixed on the appliance. Something has to move, and usually that something is a cabinet that's already screwed to the wall and scribed in.

The cost of catching this late is real. You're not just moving a panel over. You're often re-cutting a carcass, re-drilling hinge positions, sometimes ordering a whole new door panel because the old one's already machined for the wrong side. That's a wasted sheet, a wasted afternoon, and a client who's now watching you fix a mistake instead of finishing their kitchen.

• A whole sheet written off because the panel was already cut and drilled for the wrong hinge side
• A second site visit you weren't paid for, because the fix couldn't happen on install day
• A schedule slip that pushes the next job back too, since fitters rarely have a spare day sitting empty
• A client who starts double-checking everything else you've done, because trust just took a hit
• Hours spent explaining why it happened instead of hours spent finishing the kitchen

So here's the fix, and it's not complicated. It just has to happen before the carcasses get built, not after the appliance shows up.

• Pull the full installation data sheet for the exact model, not just the cutout dimensions on the box or the showroom card
• Check the door swing clearance the manufacturer actually specifies — most integrated fridges want a clear 250 to 300mm to the side of the hinge for full internal access
• Add the handle depth on top of the panel thickness when you're working out how far a door sticks out when open, not just when closed
• Confirm the custom panel depth the appliance is designed for — most sit in a 16 to 19mm range, and a panel outside that range can bind on the hinge mechanism
• Decide hinge side based on the room, not the catalogue default — a fridge hinged the wrong way can block a doorway or jam against an island just as easily as a wall
• Mock up the door swing with a scrap of card or ply before you commit a cabinet to that spot, especially in a tight run
• Check a dishwasher's open door path against the drawer or cabinet right beside it — a downward-opening door can trap a drawer shut if they're too close
• Order doors and panels only once the appliance model is confirmed, not before — a spec change mid-job is exactly how mismatched panels happen

That hinge-side point trips up more fitters than it should. It's easy to default to whatever hinge side the appliance ships with, because that's the one in stock. But the room doesn't care what's in stock. If the wrong hinge side means the door can only open 90 degrees instead of 115, you've built a fridge that technically works and practically doesn't.

Handle collisions are the one that catches people out even on a good layout. Put a fridge and a dishwasher side by side, both with bar handles on the edge closest to each other, and open both doors at once. If nobody checked, those handles meet in the middle. It's a small thing on a plan and an annoying thing every single day the kitchen gets used, because someone's always opening both at once.

The cardboard mock-up is the cheapest insurance in this whole list. Cut a piece to the door's width and depth, tape it to a scrap batten at the hinge point, and swing it through its full arc in the actual spot. It takes five minutes and it costs nothing. It's also the only way to really feel whether a door is going to clip a worktop edge, a wall, or the cabinet next to it, because a tape measure tells you a number and a mock-up shows you the problem.

Dishwashers cause a quieter version of the same problem. The door drops down and out, not sideways, so it's easy to assume it won't interfere with anything. But drop it right next to a corner base unit or a run of narrow drawers, and the open door can sit exactly where a drawer needs to swing clear. Both appliances being unusable at the same time might be fine. Nobody planning for it is the actual problem.

Islands make this worse, not better. A dishwasher built into an island, facing the main run of base units across a walkway, needs that walkway to stay clear even with the door fully down and someone kneeling in front of it loading plates. On paper the walkway's wide enough. In practice, with the door down and a body in front of it, it isn't.

Side gaps matter too, and they're easy to skip past because they look small on the page. A built-in fridge might only need a quarter to half an inch down each side, plus an inch or two above for ventilation. Shave even one of those down to make a run of cabinets look tighter, and the appliance either won't seal properly or won't vent properly. Neither shows up the day you fit it. Both show up months later as a service call.

None of this is hard to check. It just has to happen at the measuring and ordering stage, not the fitting stage. A five or ten minute look at the actual data sheet, before a single panel gets cut, is the whole fix. The expensive version of this mistake is finding out on install day, with the client standing in the kitchen watching you work out what went wrong.

It's worth building this into your routine the same way you'd check a wall for square before scribing to it. Pull the data sheet when you confirm the appliance model, not when it turns up on a pallet. Write the swing clearance and the handle depth straight onto your plan next to the cutout size, so it's sitting there when you order panels, not buried in a PDF you looked at once.

This matters more now than it used to, because kitchens keep getting tighter. Islands are bigger, runs are longer, and appliances are squeezed into spots that used to be left as gaps. There's less slack in a modern layout to absorb a door that opens wider than planned. A clearance mistake that would've gone unnoticed in a roomier kitchen ten years ago is the thing that stops a drawer opening today.

The jobs that go smoothly aren't the ones where nothing could've gone wrong. They're the ones where someone checked the door swing before the sheet got cut, not after.
