Use Case
Adelaide hospitality operators keep asking us the same three questions before summer: how big a cool room do I actually need, what panels should it be built from, and what will it cost? This guide answers all three in plain English — no sales fog, no hire-company upsell — from the perspective of the manufacturer that actually presses the panels.
If you run a cafe, restaurant, pub kitchen, bakery or catering venue in South Australia, a walk-in cool room is the single biggest cold-storage decision you’ll make. Get the size and panel spec right and it pays for itself in reduced spoilage and bulk-buying power. Get it wrong and you’re either cramming stock into a room that ices up its own evaporator, or paying to cool empty air.
Why a walk-in beats another upright fridge
Once a hospitality kitchen needs more than about two or three commercial upright fridges, a walk-in cool room is cheaper per litre of storage, easier to organise, and far more energy-efficient to run than a wall of reach-ins. A single well-insulated room holds one temperature, uses one refrigeration circuit, and lets staff walk in and pull a full crate rather than opening five doors.
❄️ The manufacturer-direct angle
Most Adelaide hospitality buyers are quoted by refrigeration installers or coolroom-hire firms who buy panels from a manufacturer and add margin. Cool Room Masters presses the EPS and PIR panels here, so you can buy the shell direct and have your own fridgie fit the plant — or take a complete supply-and-install. Either way the reseller markup on the panels disappears. See our buy-direct panel page.

Step 1 — Size the room to your busiest day
The classic mistake is sizing to an average week. Size to your biggest delivery day plus roughly 20% headroom, because that’s the moment the room is full and the door is opening every 90 seconds. Under-size it and warm air infiltration plus packed shelving chokes airflow around the evaporator.
Use this as a starting point, then confirm against your menu, delivery frequency and cover count:
| Venue type | Typical footprint | Approx. volume | Notes |
|---|---|---|---|
| Small cafe / coffee shop | 1.5m × 1.5m | ~3.4 m³ | Milk, dairy, prepped items, a few crates of produce |
| Busy cafe / small bistro | 2m × 2m | ~5.6 m³ | Adds bulk produce, weekend catering buffer |
| Mid-size restaurant (80–150 covers) | 2m × 2.4m – 2.4m × 3m | ~7–12 m³ | Separate raw/cooked zones, meat and produce together |
| Pub kitchen / function venue | 2.4m × 3m+ | 12 m³+ | Often paired with a separate freezer room |
Not sure how that footprint translates into panels? Our panel calculation guide walks through wall, ceiling and floor counts step by step.
Step 2 — Choose the right panel: thickness and core
A hospitality cool room lives or dies on its insulation. Two decisions matter: how thick the panel is, and what the core is made of.
Thickness
For a standard 2–4°C hospitality cool room, 75mm is the workhorse. Step up to 100mm when the room doubles as a freezer, backs onto a hot western wall, or sits in a kitchen that pushes past 30°C on an Adelaide summer afternoon. Thicker panels cost a little more up front and reclaim it in lower running costs.
| Panel thickness | Best for | Typical temp range |
|---|---|---|
| 50mm | Light-duty coolroom, mild ambient | 4–8°C |
| 75mm | Standard hospitality cool room (recommended) | 2–4°C |
| 100mm | Freezer, hot ambient, energy-priority builds | −18°C to 4°C |
Full breakdown in our 50mm coolroom panel buyer’s guide.
EPS vs PIR core
Both cores work in hospitality. EPS (expanded polystyrene) is the cost-effective, proven choice for the vast majority of cafe and restaurant cool rooms. PIR (polyisocyanurate) gives a higher insulation value per millimetre and a better fire rating, which matters for tight installs or where a freezer sits inside an occupied building. For a full commercial comparison, read EPS vs PIR cold room panels.
⚠️ Don’t forget the floor
Cool rooms above 2°C often run happily on a sealed concrete slab. But if the room will ever drop toward freezing, or sits on an upper floor, you need an insulated floor panel — otherwise you get condensation, frost heave and a cold slab radiating into the space below. Decide this before the shell is quoted.

Step 3 — Budget: what a hospitality cool room actually costs
Cost splits into three buckets: the panel shell, the door, and the refrigeration plant plus install. Panels for a small hospitality room start in the low thousands; a complete installed walk-in with refrigeration typically lands in five figures depending on size, door type, floor and the condensing unit you choose.
The single biggest lever on the shell price is who you buy the panels from. Buying manufacturer-direct strips out the reseller margin that hire firms and general installers add. For current, transparent numbers see our 2026 Adelaide cool room panel pricing guide.
Running cost is where thickness pays back
A hospitality cool room runs 24/7/365. Every millimetre of insulation you skip is heat leaking in that the compressor has to pump back out, every hour, for the life of the room. That’s why 75mm (or 100mm in a hot kitchen) usually beats 50mm on total cost of ownership even though the panel invoice is higher.
Step 4 — Compliance and food-safety basics
- Food Standards Code: potentially hazardous food must be kept at or below 5°C. Spec your room and thermostat to hold 2–4°C with headroom.
- Council / development approval: an internal freestanding walk-in is usually treated as a fixture, but external rooms, structural work or new plant can trigger development approval. Confirm with your local Adelaide council.
- SA Health fit-out: new and renovated food businesses have surface, drainage and cleanability requirements — smooth metal panel walls help you meet them.
- Hygienic surfaces: factory-coated steel panel skins wipe down easily and resist mould, unlike lined-and-rendered walls.
Buy the shell, or supply-and-install?
| Option | Best if… | Trade-off |
|---|---|---|
| Panels direct + your own fridgie | You have a trusted refrigeration contractor | You coordinate trades; lowest total cost |
| Complete supply & install | You want one point of accountability | Slightly higher, but turnkey and warranted |

The 60-second checklist before you order
- ☐ Sized to your busiest delivery day + 20%, not your average
- ☐ 75mm panels for a standard cool room; 100mm for freezer / hot ambient
- ☐ EPS for value, PIR where fire rating or tight R-value matters
- ☐ Insulated floor panel decided if room may go below 2°C or sits upstairs
- ☐ Door type and swing confirmed against your traffic flow
- ☐ Council / SA Health requirements checked before ordering
- ☐ Panels quoted manufacturer-direct to strip reseller margin
The bottom line
For most Adelaide cafes and restaurants, the sweet spot is a 75mm EPS walk-in, sized to your busiest day plus headroom, bought as close to the manufacturer as possible. Nail those three and you’ve solved the size, spec and cost questions in one decision. When you’re ready to price the shell, talk to us direct — we press the panels, so there’s no middleman between you and the factory.
Frequently asked questions
How big a cool room does a cafe or restaurant need?
Most Adelaide cafes run well on a 1.5m × 1.5m to 2m × 2m walk-in (roughly 3.4–5.6 m³). A mid-size restaurant doing 80–150 covers a night typically needs 2m × 2.4m to 2.4m × 3m. Size to your busiest delivery day plus about 20% headroom, not your average week.
What panel thickness should a hospitality cool room use?
75mm EPS or PIR is the hospitality standard for a 2–4°C cool room. Step up to 100mm if the room doubles as a freezer, sits against a hot western wall, or the kitchen runs above 30°C in summer.
How much does a commercial cool room cost in Adelaide?
Panels for a small hospitality cool room start in the low thousands; a complete installed walk-in with refrigeration is typically five figures depending on size, door, floor and plant. Buying panels direct from the manufacturer removes the reseller margin — see our pricing guide.
Do I need council approval for a cool room in Adelaide?
A freestanding internal walk-in is usually treated as fixtures/fittings, but external rooms, structural changes or new plant can trigger development approval and food-business fit-out requirements. Confirm with your local council and SA Health before you build.
