Walk-in wardrobes are sold with photographs of rooms the size of the average flat, which is how people end up trying to squeeze one into a space that should have been a very good fitted wall. The layouts are not a matter of taste. They are arithmetic, and the arithmetic is short enough to do in your head in the doorway of the room you are considering.
The corridor rule
Everything follows from two numbers. Storage is 600mm deep: that is what a hung coat needs. A person needs about 900mm of clear width to stand, turn, crouch to a drawer and pull it open without backing into the rail behind. Storage plus passage: 1.5m of clear width for storage on one side. Storage both sides: 2.1m by the raw sum, and in practice we draw for 2.2 or more so both sides open without negotiation. Checkatrade’s guide draws its own threshold in the same place, at a space beyond roughly 1.5m by 2.5m, and the agreement is no accident. Below these widths a walk-in is a corridor that scrapes your shoulders, and the room will punish you for the photograph.
One side, two sides, or a U
The galley, storage down one long wall, is the entry layout and suits converted box rooms and the slice carved from a large bedroom. Two facing runs double capacity where the width allows, and want the hanging split by logic: long hanging and folding on one side, short hanging doubled up on the other. The U wraps three walls and is where a walk-in starts behaving like a dressing room proper, with the end wall taking shoes or a mirror. The door decides more than people expect: every layout starts by asking where you enter, because the entry wall mostly cannot carry storage, and a corner entry frees more wall than a centre one.
The island test
The island is the photograph everyone arrives holding. It has to pass the sum in both directions: the island itself runs 600mm to a metre deep, and it wants 900mm of clearance on all four sides, because an island you sidle past is worse than no island. That puts honest islands in rooms upwards of about three metres wide. Where the room is close but not quite, the answer is usually a peninsula: drawers running off the end of one wall, clearance on three sides, most of the ritual at half the appetite.
Run the sum before you fall in love with the photograph: 600 for the clothes, 900 for you.
Light, mirrors, and the door
Most walk-ins have no window, so light is designed, not hoped for: washes down the hanging so colour reads true in the morning, light inside the drawer stack, and a mirror with even light beside it rather than above it. Doors off the bedroom want to be pocket or portal where possible, because a swinging door spends floor in both rooms. And a full-height mirror on the end wall does double duty, finishing the outfit and doubling the apparent length of the room, which every galley is grateful for.
When the honest answer is a fitted wall
If the room offers less than the corridor rule demands, the walk-in is the wrong tool, and we will say so at the survey. A fitted run with a properly designed interior, double hanging, drawer stacks, lit rails, holds more than a cramped walk-in in the same footprint, because it spends no floor on the corridor. The dressing-room feeling, clothes visible, a place to stand, somewhere to sit, can be built into a bedroom without the extra room. What the walk-in uniquely offers is the door that closes on it all. Whether that door is worth the square metres is the real question, and it is one the tape measure answers before taste gets a vote. What the room costs once the layout is chosen is in the walk-in cost guide.
Questions
What size room do you need for a walk-in wardrobe?
From about 1.5m of clear width for a single-sided layout, with Checkatrade’s guide putting the practical threshold at a space beyond roughly 1.5m by 2.5m. Two-sided layouts start at 2.1m by the arithmetic, and we draw for 2.2 or more.
What size does a walk-in wardrobe island need?
The island itself runs around 600mm to 1m deep, and it wants roughly 900mm of clearance on every side, which is why islands only work in rooms from about three metres wide.
Can a box room become a walk-in wardrobe?
Often, and it is one of the best uses of one: a 2m by 2.5m box room takes an L-shaped layout comfortably. The box room’s flaw as a bedroom, being too small for a bed and a wardrobe together, is irrelevant to a dressing room.
Does a walk-in wardrobe need a door?
Off a bedroom, an open portal or a pocket door often serves better than a swinging door, which spends floor on both sides. What a walk-in does need is designed lighting, because most have no window and borrowed light flatters nothing.
