By the Ruibit engineering team, which has manufactured and exported commercial seafood display and holding tanks to fish markets, supermarkets, restaurants, and distributors across 20+ countries since 2015.
Abstract:
A commercial seafood tank costs $2,150–4,500 FOB for a 500–1,000 L unit and $7,400–11,100 for a 4,000 L market bank, split into three blocks: structure (40–55%), cooling (25–35%), and delivery packaging (10–15%). The quote you compare should separate those three lines — a lump-sum price hides which part of the tank is driving your number.
Three Cost Blocks, Three Different Rules
A seafood tank is not one product but three purchases bolted together:
- Structure — the stainless steel or glass body that holds water and lives with saltwater. Price is set by material grade, glass type, and fabrication.
- Cooling — the chiller that keeps live product at 16–20°C. Price is set by capacity, heat-exchanger material, and tropical headroom.
- Delivery — export crating, freight, and installation. Price is set by distance, access, and who does the hook-up.
Each block moves on its own logic, which is why two "same-size" quotes from different factories rarely line up: one may build in 316 stainless, another in 304, and a third in coated steel with a "marine" label.
The Breakdown by Tank Size
The figures below are FOB factory with export packing, industry-typical for a commercial market display in standard 304 stainless with low-iron viewing glass and a titanium heat-exchanger chiller. Actual numbers move with grade, market, and climate.
| Tank size (L) | Structure | Cooling | Delivery packaging | FOB total range |
|---|---|---|---|---|
| 500 | $1,200–1,700 | $700–1,000 | $250–400 | $2,150–3,100 |
| 1,000 | $1,800–2,600 | $900–1,400 | $300–500 | $3,000–4,500 |
| 2,000 | $2,800–4,000 | $1,400–2,200 | $450–700 | $4,650–6,900 |
| 4,000 | $4,500–6,500 | $2,200–3,500 | $700–1,100 | $7,400–11,100 |
Two things stand out. Structure is the biggest single line in every tier, and cooling grows faster than structure as tanks get bigger — because heat gain scales with surface and load, not just volume. A 4,000 L tropical market bank can spend a third of its budget on chilling.
What Moves Each Block
Each block has its own cost amplifiers, and knowing them stops a $500 surprise.
| Cost amplifier | Effect on the block |
|---|---|
| 316 vs 304 stainless | Structure +15–25% |
| Low-iron glass vs float | Structure +20–30% |
| Extra bracing or double-wall build | Structure +10–20% |
| Chiller upsized for 32°C ambient | Cooling +40–60% |
| Titanium vs copper heat exchanger | Cooling +15–25% |
| Remote installation, crane, water hook-up | Delivery +30–60% |
The cheapest way to control the total is to specify grade and climate in the RFQ. A tank "built for tropical markets" with no chiller headroom is a cooling re-quote waiting to happen.
A Worked Example
A wholesale fish market priced a 1,000 L display three ways (hypothetical, for budgeting):
| Option | Structure | Cooling | Delivery | FOB total |
|---|---|---|---|---|
| Standard 304, float glass, 1,000 W chiller | $1,950 | $950 | $380 | $3,280 |
| 304 + low-iron glass, 1,500 W chiller | $2,300 | $1,250 | $380 | $3,930 |
| 316 + low-iron, 2,000 W tropical chiller | $2,750 | $1,650 | $420 | $4,820 |
The market chose the middle option — low-iron glass for the customer-facing view and a 1,500 W chiller for 30°C summers — paying $650 over the baseline but avoiding the $900 re-quote that a too-small chiller would have triggered within the first hot month.
How to Buy on a Comparable Breakdown
Three habits keep seafood tank quotes honest:
- Ask for the three blocks as separate lines: structure, cooling, delivery. Reject a single lump sum.
- Specify grade, glass, and ambient temperature in the enquiry — "304 stainless, low-iron glass, 30°C ambient" prices a different tank than "marine-grade, 25°C."
- Separate purchase cost from running cost. The chiller that is cheapest to buy is rarely cheapest to run; ask for input power and an annual energy estimate alongside the price.
Ruibit quotes commercial seafood tanks on exactly these three lines — structure, cooling, and delivery — with the chiller input power and a monthly energy estimate attached, so the CAPEX and the OPEX are both known before the PO.
Send the tank size, species load, ambient temperature range, and delivery destination, and we will return a three-line breakdown with chiller sizing and running-cost estimate.

FAQs
How much does a commercial seafood tank cost?
FOB factory: $2,150–3,100 for 500 L, $3,000–4,500 for 1,000 L, $4,650–6,900 for 2,000 L, and $7,400–11,100 for 4,000 L, including export packing.
Why do quotes for the same-size tank differ?
Scope and grade. Structure is 40–55% of price, cooling 25–35%, delivery 10–15%. 316 stainless, low-iron glass, and tropical chiller headroom each add 15–30% to their block.
What makes the cooling line grow fastest?
Heat gain scales with surface and load. A 4,000 L tropical market bank can spend a third of its budget on chilling, and upsizing for 32°C ambient adds 40–60% to the chiller block.
How should a seafood tank quote be structured?
As three separate lines: structure, cooling, delivery. Reject a lump sum, and state grade, glass, and ambient temperature in the enquiry so the quote is comparable.
Should I compare running cost too?
Yes. The cheapest chiller to buy is rarely the cheapest to run. Ask for input power and an annual energy estimate alongside the price, then compare total cost, not just FOB.
