How much space do you need in front of a changing room bench?

Allow at least 1,000 mm of clear floor in front of a single-sided bench so someone can stand, bend and dress without stepping into a walkway, and 1,200 to 1,500 mm between two benches that face each other, because two people are bending into the same space at once. Add the locker door swing separately: a door is typically 300 to 400 mm of arc and it opens into that same zone, so a bench 900 mm from a bank of lockers leaves about 500 mm of usable standing room when a door is open.

How many metres of bench do I need for a given number of people?

Size on peak headcount rather than total headcount, then allow 450 to 600 mm of seat per person. Use 450 mm for children and tightly managed shift changes and 600 mm where people bring kit bags and will spread out. Twenty adults changing together therefore needs roughly 9 to 12 linear metres of seat. In workplaces where many users stand at a full-height locker and never sit, sizing at 70 to 80 percent of peak headcount is usually realistic.

When should I use a double-sided island instead of wall benches?

It is a room-width decision, not a seat-count one. Under about 2.5 m of clear width you have one wall run and nothing else. Between roughly 2.5 m and 4 m, two facing single-sided runs work and an island does not. Above about 4 m an island down the centre with single-sided runs on the walls is the efficient layout, because it doubles seating per square metre and frees both walls for lockers. A double-sided bench is 710 mm deep against 310 to 375 mm for single-sided, so it is not twice the depth.

What seat height should a changing room bench be?

The three frame designations give seat heights of Infant 350 mm, Junior 400 mm and Senior 475 mm. Senior is roughly standard chair height and suits adult workplaces, Junior suits primary and lower-secondary, and Infant lets a small child sit with both feet flat on the floor. On school orders, note that the published overall height of the coat-hook and overhead-rail benches is 1,840 mm for all three designations, so ask for the hook centre height to be confirmed against the drawing if reachable hanging is the reason for choosing Infant height.

What lengths do changing room benches come in?

The orderable lengths are 1,000, 1,200, 1,500 and 2,000 mm, run end to end to make a continuous length. There is no 1,800 mm bench in the range, despite the figure appearing in a good deal of product copy, so do not plan a wall run on an 1,800 mm module. Note also that the 1,200 mm module exists only on the double-sided ranges, so it is available for islands but not for every wall configuration.

Should changing room benches be bolted to the floor?

In any high-traffic room, yes. Freestanding benches get dragged, leaned on and climbed on, and they end up narrowing the route people leave by. Floor-fixing brackets and full ironmongery are supplied but the floor fixings themselves are not, and the right anchor for screeded concrete is not the right anchor for suspended timber, for a tiled wet-side floor with a waterproof membrane, or for a floor with underfloor heating. Establish the floor construction before the installer arrives.

Beech or polymer slats for a changing room bench?

Beech is a dry-room specification: offices, clubs, staff changing and school cloakrooms, where it is comfortable and looks right. Polymer belongs anywhere water reaches, including poolside, wet-side changing, shower lobbies and food production, and anywhere benches are cleaned with chemicals that would gradually degrade a timber finish. In a leisure facility the answer is usually both, and because the frames are identical the two finishes read as one scheme. Draw the wet and dry line on the plan before choosing slats.

How should benches and lockers be arranged together?

Treat them as one system. Plan roughly one locker per user and one bench place per 1.2 to 1.5 users in a workplace, or one bench place per child at peak in a school, because pupils all arrive at once. Do not put a bench directly in front of the lockers it serves, because a seated person blocks the bank behind them; offset the run or face the bench away. Aim for a straight line from door to locker to seat to door, since any layout that makes users cross the room twice feels crowded at half its intended occupancy.

Changing Room Layout: How to Plan Bench Seating

Most changing rooms are not badly equipped. They are badly laid out. The benches are the right benches, and there are enough of them, but two people cannot pass behind a third who is bending down to tie a boot — so at the end of a shift or the start of a PE lesson the room jams. That is a planning problem, and it is decided before anything is ordered.

This guide is about the room. Where the benches go, how much floor they need, how many people they actually seat at peak, how they relate to the lockers, and what to check on delivery day. If what you need is the product side — dimensions, configurations, seat heights, prices and the single-versus-double-sided cost arithmetic — that all lives on the changing room and cloakroom benches page, and this guide will point you at it rather than repeat it.

Start from peak headcount, not from the wall

The commonest sizing mistake is measuring the walls and filling them. Start at the other end.

Count the peak, not the total. A 60-person site with three staggered shifts may never have more than 25 people changing at once. A 30-child class arrives all at once, every time.
Allow 450–600 mm of seat per person. Use 450 mm for children and tightly managed shift changes, 600 mm where people bring kit bags and coats and will spread out.
Multiply. Twenty adults changing together needs roughly 9 to 12 linear metres of seat.
Only then look at the walls. If your perimeter cannot carry that many metres of single-sided bench with circulation left over, the room needs an island — and that is a floor-width question, covered next.

One qualifier worth applying honestly: not everyone sits. In a room with full-height lockers, a proportion of users stand at the locker and never use the bench at all. If you are fitting out a workplace rather than a school, sizing at 70–80% of peak headcount is usually realistic, and the money saved is better spent on getting the circulation right.

The number that decides the layout is depth, not seat count

Bench length is what people compare. Bench depth is what determines whether the room works, and it does not scale the way most people assume. Across the Probe range the depths are:

Single-sided with undershelf or baskets — 310 mm
Single-sided with hooks, overhead rail, or low seat — 375 mm
Double-sided, every configuration — 710 mm

A double-sided bench is not twice the depth of a single-sided one. Two opposing wall runs cost you 750 mm of bench depth plus two circulation zones — one in front of each wall. One double-sided island seats the same people in 710 mm and needs circulation on both sides of a single object. In a narrow room that is the whole argument for an island, and it has nothing to do with how many people it seats.

Circulation: the figures to plan against

These are planning allowances, not regulations, and they assume adults with bags:

1,000 mm minimum clear in front of a single-sided bench — enough to stand up, bend and dress without stepping into a walkway.
1,200–1,500 mm between two benches that face each other, because two people are bending into the same space at the same time.
Add the locker door swing separately. A locker door is typically 300–400 mm of arc, and it opens into the zone you have just measured. A bench 900 mm from a bank of lockers has, in practice, about 500 mm of usable standing room when a door is open.
Keep a clear route to the exit that no bench narrows. Benches migrate if they are not fixed, and the direction they migrate is into the aisle.

A useful sanity check: a single-sided hook bench against a wall occupies 375 mm of bench plus 1,000 mm of circulation = 1,375 mm from the wall before anything else can go there. Two facing runs need about 2,150–2,450 mm of room width. A central island needs 710 mm plus circulation on both faces — roughly 2,700–3,200 mm — but frees both walls for lockers. That comparison, not the seat count, is how the layout gets decided.

Wall runs, islands, or both

Under about 2.5 m of clear width, you have one wall run and nothing else. Use single-sided benches and put lockers on the opposite wall, offset so door swings and seated users are not in the same place.

Between roughly 2.5 m and 4 m, two facing single-sided runs work and an island does not — there is not enough width for circulation on both faces plus anything on the walls.

Above about 4 m, a double-sided island down the centre with single-sided runs on the walls is the efficient layout, and it is the standard school and leisure arrangement for a reason: it doubles seating per square metre of floor and leaves both walls free for lockers.

One point of arithmetic that surprises people, and which is set out in full with prices on the collection page: in a room wide enough for two single-sided wall runs, two single-sided rail-and-basket benches can cost less than one double-sided equivalent — because the second side of a double-sided bench duplicates the hanging and the storage, not just the seat. Islands earn their place on floor width, not on budget.

Bench-to-locker ratio and flow

Benches and lockers are one system. Get the sequence right and the room self-organises; get it wrong and everyone stands in the same square metre.

One locker per user, one bench place per 1.2–1.5 users is a reasonable workplace starting point. In schools, plan one bench place per child at peak — they all arrive together.
Do not put the bench directly in front of the lockers it serves. A seated person blocks the bank behind them. Offset the run, or face the bench away.
Give people a straight line: door → locker → seat → door. Any layout that makes users cross the room twice will feel crowded at half the occupancy it should take.
Match the colours deliberately, not decoratively. The frames come in seven colours and the colour does not change the price, so colour-coding year groups, home and away rooms, or departments costs nothing.

For the locker half of the specification, see metal lockers and the guide to choosing workplace lockers; for schools, the school lockers buying guide; for leisure, gym and leisure lockers. Locking is its own decision — see locker lock types explained.

Seat height by user group — and the caveat that matters for schools

The Probe frames come in three designations, and the seat heights are Infant 350 mm · Junior 400 mm · Senior 475 mm. Senior is roughly standard chair height and suits adult workplaces; Junior suits primary and lower-secondary; Infant lets a small child sit with both feet flat on the floor, which is what stops a nursery cloakroom becoming a scrum.

One thing to check before a school order, because it is not obvious from the product data. On the coat-hook and overhead-rail benches, the published overall height is 1,840 mm for Infant, Junior and Senior alike. The age designation changes the seat height; on the published figures it does not change the overall frame height. If the reason you are specifying Infant height is so that four-year-olds can reach their own coats, ask for the hook centre height to be confirmed against the drawing before you order — that is the dimension that decides it, and it is not the one printed on the listing. Where reachable hanging is the whole point, the low-seat and undershelf formats are worth looking at instead.

Wet side and dry side: zone the room before you choose slats

Seat slats come in beech or black polymer, and the choice is environmental rather than aesthetic. Beech is a dry-room specification. It is comfortable and looks right in offices, clubs, staff changing and school cloakrooms. It is the wrong material anywhere the bench is regularly wet or gets hosed and disinfected.

Polymer belongs anywhere water reaches: poolside, wet-side changing, shower lobbies, food production, and any room cleaned with chemicals that would gradually degrade a timber finish. In a leisure facility the practical answer is usually both — polymer on the wet side of the barrier, beech in the dry village changing rooms — and because the frames are identical, the two look like one scheme.

The zoning decision comes before the bench decision. Draw the wet/dry line on the plan first, then specify to each side of it.

Length modules — and a correction worth making

Benches are ordered in modules and run end to end to make a continuous length. The orderable lengths are 1,000, 1,200, 1,500 and 2,000 mm.

An earlier version of this guide, and a good deal of product copy elsewhere, refers to a standard 1,800 mm bench. There is no 1,800 mm bench in this range. If you plan a wall run on an 1,800 mm module you are planning against something you cannot order, and a 9 m wall becomes five awkward units instead of a clean layout. Plan on the real four:

9 m = 4 × 2,000 + 1,000, or 6 × 1,500
6 m = 3 × 2,000, or 4 × 1,500, or 5 × 1,200
4.4 m = 2 × 2,000 + 1,200

Note also that 1,200 mm exists only on the double-sided ranges, so it is available for islands but not for every wall configuration. Confirm the module before drawing the run.

Fixing, escape routes and what is under the floor

Freestanding benches in a busy changing room move. They get dragged, leaned on and climbed on, and they end up narrowing the route people leave by. Fix them down.

Floor-fixing brackets and full ironmongery are supplied. The floor fixings themselves are not. That is the single most common delivery-day gap on this product, and it is not a trivial one: the right anchor for a screeded concrete floor is not the right anchor for suspended timber, for a tiled wet-side floor with a waterproof membrane you must not puncture, or for a floor with underfloor heating in it. Establish the floor construction before the installer arrives, and if there is a membrane or heating below, resolve the fixing method at design stage rather than on the day.

Accessibility

The Equality Act 2010 requires changing provision to be usable by disabled people, and the practical implication for bench layout is straightforward: at least one bench position with clear transfer space to the side of it, so a wheelchair user can come alongside rather than approach head-on. In practice that means a 900 mm–1,000 mm clear zone at one end of a run, kept free of lockers and hooks. Back support is worth providing at that position if the room allows. For a public leisure facility, check the current Approved Document M guidance for accessible changing rooms before the layout is signed off — bench heights and transfer spaces are specified there, and retrofitting them is expensive.

Delivery day

Two things to plan for, both of which have caught people out:

These are welded frames, delivered assembled. A 2,000 mm double-sided overhead-rail bench arrives as a single 710 × 1,840 mm welded structure. Check the doorway, the lift, the stair turn and the turning circle on the route from the lorry to the room before the delivery is booked. A bench that will not go round the corner is not a bench that can be dismantled at the door.
Order the fixings as a separate line, once you know the floor.

A worked example

A secondary school PE changing room, 5.2 m × 7 m, 28 pupils changing at once.

At 450 mm per pupil that is 12.6 m of seat. The perimeter cannot carry it once doors and the shower entrance are deducted, and 5.2 m of width is comfortably over the 4 m island threshold. So: a 6 m double-sided island (3 × 2,000 mm) down the centre gives 12 m of seat on its own, with two 3 m single-sided hook runs on the long walls adding 6 m more — 18 m total, ample at peak and comfortable off-peak. Width check: 710 mm island + 1,200 mm circulation each side + 375 mm bench each side = 3,860 mm, leaving over 1.3 m for lockers on one wall. Junior or Senior height depending on year group, beech slats because it is a dry room, and every unit floor-fixed.

Planning checklist

Peak headcount, not roll number — then 450–600 mm of seat each
Room width first: under 2.5 m one run · 2.5–4 m two runs · over 4 m an island
Depths: 310 mm undershelf/basket · 375 mm hook/rail/low-seat · 710 mm double-sided
Circulation: 1,000 mm in front of a run, 1,200–1,500 mm between facing runs, plus locker door swing
Heights: Infant 350 · Junior 400 · Senior 475 mm — and confirm the hook centre height on school orders
Zoning: draw the wet/dry line, then beech dry side, polymer wet side
Modules: 1,000 / 1,200 / 1,500 / 2,000 mm — there is no 1,800 mm bench
Fixing: brackets supplied, floor fixings are not — establish the floor construction first
Accessibility: one bench position with side transfer space
Access route checked before the lorry is booked
