Use Case
Building a cool room in Australia costs anywhere from $4,000 to $40,000+ — and where you land on that range depends on six factors that have nothing to do with luck. This guide walks through what actually drives the cost across SA, VIC, NSW, QLD, WA and TAS, what you can realistically build for each budget tier, and where most first-time buyers leak money. Real 2026 numbers from a stocking Adelaide supplier.
TL;DR: A standard 3m × 4m × 2.4m walk-in cool room runs ~$1,880 in EPS panels + $3,000–6,000 for refrigeration plant + $1,500–3,500 install = roughly $6,500–11,500 supplied and installed. Adelaide stock saves $250–450 in interstate freight versus Melbourne/Sydney suppliers. Request a quote or use the cool room calculator.
What Goes Into a Cool Room Cost?
Most first-time buyers assume “cool room cost” = panel price. That’s about a third of the real number. A working cool room has four cost components you need to budget for:
| Component | Typical % of total | What it is |
|---|---|---|
| Insulated panels & door | 30–45% | Wall, ceiling, floor (if insulated), door with gaskets, joinery channels |
| Refrigeration plant | 25–40% | Evaporator, condensing unit, refrigerant, controls |
| Installation labour | 15–25% | Panel erection, refrigeration commissioning, sealing |
| Site work & electrical | 5–15% | Concrete slab, 3-phase or single-phase power supply, lighting, alarms |
The number that varies most is the refrigeration plant — a chiller for +2 to +5°C is roughly half the cost of a freezer plant running –18°C. The panels are the most predictable line item, and the one you can shop hardest on.
Average Cool Room Cost in Australia (2026)
Indicative supplied-and-installed budgets for the most common cool room types:
| Cool Room Type | Typical Size | Cost Range (Supplied + Installed) |
|---|---|---|
| Small chiller (residential, café, bottle store) | 3 × 3 × 2.4m | $6,000 – $11,000 |
| Medium commercial cool room | 5 × 4 × 2.7m | $10,000 – $18,000 |
| Walk-in freezer (–18°C) | 5 × 5 × 2.7m | $15,000 – $28,000 |
| Large / industrial cold store | Custom >30m² | $28,000 – $80,000+ |
Quoted ranges assume a stocked supplier within delivery range and a licensed refrigeration mechanic. Add 10–20% for projects requiring engineered floor slabs, BCA fire-rated panels (PIR or Rockwool), or council development approval.
Cool Room Cost by Size — How the Numbers Scale
Panel area scales with both floor size and ceiling height. A taller ceiling adds more wall panel than most people expect.
| Floor Footprint | Ceiling | Wall Panel Area | Ceiling Panel | Total m² |
|---|---|---|---|---|
| 2.4m × 2.4m | 2.4m | ~23 m² | ~6 m² | ~29 m² |
| 3m × 3m | 2.4m | ~29 m² | ~9 m² | ~38 m² |
| 3m × 4m | 2.4m | ~34 m² | ~12 m² | ~46 m² |
| 4m × 5m | 2.7m | ~49 m² | ~20 m² | ~69 m² |
| 5m × 6m | 2.7m | ~59 m² | ~30 m² | ~89 m² |
At Cool Room Master, 50mm EPS Z-lock panels are $41.74/m² (1150mm cover width). Multiply your total m² by that rate for a panel-only estimate. For the full Adelaide-specific pricing breakdown with per-length panel prices and accessories, see our 2026 Adelaide pricing guide.
Cool Room Cost by State
The cool room itself costs the same — what changes is freight and refrigeration mechanic rates. Adelaide is our base; everything else picks up interstate freight or higher labour rates depending on the city.
| State / Capital | Freight from Adelaide | Refrigeration mechanic rate |
|---|---|---|
| SA (Adelaide metro) | Same-week, low cost | $90–130/hour |
| VIC (Melbourne) | Interstate freight applies | $110–150/hour |
| NSW (Sydney) | Interstate freight applies | $120–160/hour |
| QLD (Brisbane) | Interstate freight applies | $110–150/hour |
| WA (Perth) | Significant interstate freight | $120–160/hour |
| TAS (Hobart / Launceston) | Bass Strait freight surcharge | $110–140/hour |
| NT (Darwin) | Highest freight; long lead time | $130–180/hour |
For an Adelaide-stocked supplier shipping panels around Australia, freight is quoted per job — depends on volume, weight and postcode. The bigger cost differential between states usually shows up in refrigeration mechanic rates, not the panels.
Cool Room Cost by Temperature: Chiller vs Freezer
The temperature you’re holding the room at drives both panel thickness and refrigeration plant size. A freezer is roughly 40–80% more expensive than a chiller of the same footprint.
| Application | Hold Temp | Recommended Panel | Refrigeration Plant |
|---|---|---|---|
| Wine, beverage chiller | +8°C to +12°C | 50mm EPS | Small split unit, ~$2,000–3,500 |
| Cool room (standard) | +2°C to +5°C | 50mm EPS | Mid-size condenser, ~$3,000–5,500 |
| Cold storage (high turnover) | 0°C to +2°C | 75mm EPS or PIR | Mid-large condenser, ~$4,500–7,000 |
| Walk-in freezer | –18°C | 75mm PIR (preferred) or 100mm EPS | Freezer condenser, ~$5,500–9,500 |
| Blast freezer / industrial | –25°C and below | 100mm PIR | Custom plant, $10,000+ |
The single biggest mistake we see: people specify 50mm EPS for a freezer to save $500 on panels, then pay $1,500 more in electricity every year because the compressor is fighting an inadequate insulation barrier. EPS vs PIR vs Rockwool guide covers the decision in detail.
Cool Room Cost by Industry
Restaurants & Cafés
Typical build: $6,000–11,000 supplied and installed for a 3m × 3m chiller. Common spec: 50mm EPS Z-lock, single-phase condensing unit, stainless steel door. Usually doesn’t need engineered floor — sits on existing concrete.
Butchers, Bakeries & Seafood
Typical build: $10,000–18,000. Two-room setup (chiller + freezer) is common. Spec: 50mm chiller wall, 75mm freezer wall, heavier-duty floor panels. Hygienic Surfmist Colorbond skin throughout.
Supermarkets & Independent Grocers
Typical build: $18,000–40,000+. Multiple rooms, higher daily turnover, often requires shelving fit-out as well. Refrigeration plant is the dominant cost.
Hospitality (Pubs, Bottle Stores, Hotels)
Typical build: $8,000–18,000. Cool rooms for keg storage, wine cellars and bulk beverage. Often integrated into existing buildings, so panel-and-install is the main line item.
Warehousing & Cold Logistics
Typical build: $25,000–80,000+. Larger footprints, ceiling heights up to 4m, often requires engineered insulated slabs and 3-phase refrigeration plant. Council DA usually required.
Pharmaceutical, Medical, Laboratory
Typical build: $20,000–45,000+. Tight temperature tolerance (+2°C ±2°C is typical), redundant refrigeration, alarm and chart-recorder requirements. Documentation overhead is significant.
Upfront Cost vs Lifetime Cost
The number on your initial invoice isn’t the only number. A cool room’s true cost includes electricity over its 15–20-year life. A small upgrade to thicker or higher-grade panel insulation can save more in power bills than it added to the build.
| Scenario (5m × 4m chiller, +3°C) | EPS 50mm | PIR 75mm |
|---|---|---|
| Upfront panel cost | ~$2,000 | ~$3,500 |
| Estimated daily electricity (Adelaide summer) | ~$5.20 | ~$3.80 |
| Annual electricity | ~$1,900 | ~$1,390 |
| 5-year energy cost | ~$9,500 | ~$6,950 |
| 5-year total (panels + electricity) | ~$11,500 | ~$10,450 |
Indicative numbers based on Adelaide ambient design conditions and standard plant. Your actual electricity cost depends on usage cycle, plant efficiency and tariff. PIR or 75mm EPS pays for itself within 2–5 years on most commercial installations.
Where DIY Saves Money — and Where It Costs You
You can save 20–40% on a cool room build by handling the panel install yourself, provided you have the tools and patience. What you should not DIY:
- Refrigeration plant install — requires a licensed refrigeration mechanic by law. Unlicensed gas work voids insurance and breaches regulations.
- Engineered floor slab — get a structural engineer if you’re building above a concrete slab or for a freezer with significant temperature differential.
- 3-phase electrical work — licensed electrician only.
What you can DIY:
- Panel cutting and installation (cut on-site with a fine-tooth circular saw)
- Aluminium track and channel fixing
- Door installation (provided you have the door hardware kit)
- Silicone sealing of internal seams
For a typical 3m × 4m cool room, DIY panel install saves $1,500–$3,000 compared to a turnkey supplied-and-installed quote. The trade-off is 1–2 days of your time and the responsibility of getting the joints sealed properly.
Hidden Costs Most Suppliers Don’t Mention
| Cost | Range | When it applies |
|---|---|---|
| Engineered floor slab | $1,000–4,000 | Freezers, large rooms, retrofit on uneven surfaces |
| Council development approval | $300–1,500 | Commercial builds, new structures, larger fit-outs |
| 3-phase power upgrade | $1,500–4,000 | If your site only has single-phase |
| Engineered fire-rated panels (PIR) | +20–40% over EPS | Multi-occupancy buildings, council DA |
| Interstate freight (non-Adelaide buyers) | $250–800 | Buying from Melbourne/Sydney supplier shipped to Adelaide etc. |
| Temperature monitoring & alarm | $400–2,000 | Pharmaceutical, food premises requiring records |

Frequently Asked Questions
How much does a cool room cost per square metre in Australia?
Panel supply alone is roughly $40–$70 per m² for 50–75mm EPS Z-lock panels. Supplied-and-installed is roughly $150–$300 per m² total floor area depending on size, temperature and complexity.
Is it cheaper to buy a prefab cool room or build one with panels?
Building from panels is almost always cheaper for commercial-grade rooms (3m × 3m and up). Prefab “kit” cool rooms can be cheaper for under-3m² applications, but you lose flexibility on dimensions and panel quality.
What’s the cheapest state to build a cool room in?
South Australia and Victoria generally have the lowest combined panel + refrigeration mechanic rates. WA and NT carry higher freight costs from east-coast suppliers. Buying from an Adelaide-stocking supplier eliminates the freight gap for SA, VIC and parts of NSW.
How long does a cool room take to build?
Panel install is typically 1–3 days for a standard commercial cool room. Refrigeration plant commissioning adds another 1–2 days. Plan for 5–10 working days from panel delivery to first cool-down for a turnkey build.
Do cool rooms need council approval in Australia?
Internal cool rooms inside an existing building usually don’t require DA. Free-standing cool rooms or builds in commercial food premises typically do. Check with your local council before committing — DA cost is $300–1,500 typically.
Can I expand a cool room later?
Yes — Z-lock EPS panels are modular, so adding a wall or extending the footprint is mechanically straightforward. Refrigeration plant capacity may need uprating to match the larger volume, so plan ahead if expansion is likely.
Is EPS suitable for Australian conditions?
Yes. EPS Z-lock panels are the standard choice for Australian commercial cool rooms in chiller applications. For freezers and applications running 24/7, step up to PIR or 75mm+ EPS for better energy economics over the long term.
