TwinThink metal lockers are 177 cm high, 40 cm deep and 65 or 97 cm wide; the only exception is the single-column model, at 165 × 33 cm and also 40 cm deep. Inside the 177 cm lockers, every compartment is 28 cm wide and 41 cm high in the 12-door, 82 cm in the 4-door and 6-door, and full height in the 2-door. The full table is below, followed by what to measure in your changing room before you order.
What size is each locker?
| Locker | Exterior (height × width × depth) | Compartment (height × width) | Door (height × width) | People per metre of wall |
|---|---|---|---|---|
| 2-door | 177 × 65 × 40 cm | Full height × 28 cm | 157 × 28 cm | 3 |
| 4-door | 177 × 65 × 40 cm | 82 × 28 cm | 78 × 28 cm | 6 |
| 6-door | 177 × 97 × 40 cm | 82 × 28 cm | 78 × 28 cm | 6 |
| 12-door | 177 × 97 × 40 cm | 41 × 28 cm | 40 × 28 cm | 12 |
| 4-door, single column | 165 × 33 × 40 cm | 41 cm high | 40 × 28 cm | 12 |
The 177 cm lockers are a 165 cm body on 12 cm legs. The single-column model has no legs and stands on the floor, which is why it stops at 165. Every model has a 28 cm wide door, and on the 177 cm lockers the compartment behind it is the same width, so anything that goes through the door fits across the inside. The last column of the table is simple arithmetic, doors divided by width in metres, rounded down. What fits in each compartment, and when each model makes sense, is in 2-door or 4-door locker: which to choose.
How much space do you need in front?
Depth is the same across the range: 40 cm. We do not make a shallower version, so if the recess you have in mind is 35 cm deep they will not fit, and it is better to know that before you ask for a quote.
With a door open, the locker takes up 68 cm from the wall: 40 cm of depth plus the 28 cm door, which opens into the walkway. In front of that there has to be room for the person getting changed, and behind them for someone walking past. If you add a bench (ours are 45 cm high and 32 cm deep, in 90 cm or 150 cm lengths), we recommend 1.2 m from the front of the lockers to the outer edge of the bench, plus a 1 m clear walkway behind it if there is another row opposite. Two facing rows with the benches in the middle come to about 2.1 m between fronts. How many benches you need and where they go is covered in changing room benches: sizes, how many you need and what the regulations say.
How high does each compartment sit?
The compartments stack, so the number of doors decides the height each person works at. In the 4-door and 6-door lockers the bottom row starts 12 cm off the floor and the top row at about 95 cm, roughly waist height. In the 12-door, the four rows start at about 12, 53, 95 and 136 cm: the top one is comfortable for an adult and high for a child, so in a school it makes sense to give younger pupils the lower rows. The 2-door has no rows; its compartment runs from top to bottom, and that is where overalls or a long coat fit without folding. In the single-column model, which has no legs, the rows start at 0, 41, 83 and 124 cm. These are our own sums on the 165 cm body, without allowing for the thickness of the steel, so treat them as approximate.
The ceiling needs to give a little more than the height of the locker. If you assemble it lying on its back and then stand it up, it sweeps through the diagonal of its side as it turns: just over 181 cm for the 177 cm lockers and just under 170 cm for the 165 cm one. Under a lower beam or suspended ceiling, stand it up where there is headroom and carry it upright to where it goes.
How many fit on your wall?
Divide the wall by the width of the locker, 65 or 97 cm, and you have the answer, though the obvious choice does not always come out ahead:
| Length of wall | With 4-door lockers (65 cm) | With 6-door lockers (97 cm) | Which comes out ahead |
|---|---|---|---|
| 2.00 m | 3 lockers, 1.95 m, 12 compartments | 2 lockers, 1.94 m, 12 compartments | A tie: decide on the rest of the changing room |
| 3.00 m | 4 lockers, 2.60 m, 16 compartments | 3 lockers, 2.91 m, 18 compartments | The 6-door, two more compartments |
| 10.00 m | 15 lockers, 9.75 m, 60 compartments | 10 lockers, 9.70 m, 60 compartments | A tie, with five fewer lockers to assemble if they are 6-door |
Every combination leaves at least 5 cm spare, enough to slot the last locker in without scraping the wall. The compartments in the table are 82 × 28 cm; with the 12-door, the same 10 m gives 120 compartments of 41 × 28 cm. And for a narrow gap between two pillars, where a 65 cm locker will not go, there is the single-column model, 33 cm wide. From the number of people and what each of them stores, the locker calculator tells you how many you need and how much wall they take. How many the law requires for your staff is in how many lockers per employee the law requires.
Sockets, skirting boards and wall fixing
Before you settle on a spot, mark the width of each locker on the wall. Whatever ends up behind a locker, be it a socket, a light switch, the thermostat or an access panel, is out of reach: to get to it you have to empty the locker, unfix it if it is fixed to the wall and pull it out.
The skirting board eats into the depth. The locker cannot sit any closer to the wall than the skirting board allows, so add its thickness to the 40 cm and you have how far it really sticks out.
Fix each locker to the wall so it cannot move or tip over; the screws and plugs are not in the box. Before you drill, check what the wall is made of: brick and concrete hold well; on plasterboard, find a stud or use plasterboard fixings.
Where should you assemble it?
In the room where it will stay. The lockers arrive unassembled, and once put together they are far bulkier: on a narrow landing they will not turn. The box weighs 20 kg for the single-column model, 31.75 kg for the 2-door and 34.2 kg for the 4-door, so if there are stairs, carry it up with two people. If you would rather not assemble it, we also sell it ready-assembled, on a pallet left at the kerbside, but only within Spain (not the Canary Islands, Ceuta or Melilla); then it is the whole locker that has to get through doors and up stairs.
Is there a legal minimum size?
No. Regulation 23 of the Workplace (Health, Safety and Welfare) Regulations 1992 requires "suitable and sufficient accommodation" for the clothing people do not wear during working hours, and paragraph (2)(a) adds that it must keep that clothing secure where regulation 24 requires changing facilities. It gives no dimensions. What counts as sufficient depends on what is stored, and for overalls or a uniform kept full length, the full-height compartment of the 2-door does the job. The rest of what the Regulations ask for is in lockers in the staff changing room: what the Workplace Regulations 1992 require. This is general guidance, not legal advice.
How to measure your changing room in five minutes
- Metres of clear wall, run by run, taking off doors, radiators and downpipes, with sockets and switches marked.
- Clear height: 177 cm of locker (165 for the single-column model), and 182 cm (170 for the single-column model) if you will stand it up in that same spot.
- Depth: 40 cm of locker, the thickness of the skirting board, 28 cm of open door and the walkway.
- What the wall is made of, for the fixing.
If you are fitting out a changing room with several lockers, ask for a quote with those measurements and the number of people; we usually reply the same working day. If you are buying for a business, give your VAT number and the invoice is made out to the company. From 15 units the basket applies a 5% volume discount automatically, and from 30 units, 10%. Delivery takes 2-3 working days from our UK warehouse, and tracking is explained on our delivery and tracking page.
