A Guide to Commercial Kitchen Sink Requirements, Regulations, and Smart Choices
Commercial sinks are a hardworking and essential part of any professional kitchen. If you’re setting up a new space or upgrading, knowing the right number and types of commercial kitchen sinks is essential for keeping your operation efficient and compliant.
Let’s break down the latest regulations, practical tips, and smart buying options—like buying commercial sinks second hand—to help you make the best choice for your business.
Why Commercial Sinks Matter in Every Kitchen
Having the right commercial sinks in place ensures that your kitchen is compliant and makes it safer, cleaner, and easier to run. Australian standards (like AS 4674) require commercial kitchen sinks that are durable, easy to clean, and correctly placed to prevent cross-contamination. Choosing high-quality stainless steel, such as 304 grade, ensures your sinks withstand heavy use and meet hygiene expectations.
Types of Sinks Required in a Commercial Kitchen
To meet commercial kitchen sink requirements and pass inspections, most kitchens need:
-
Handwashing Sinks:
Must meet strict handwashing sink standards, which means they need to be dedicated, hands-free, and supplied with hot and cold water. These are essential for commercial kitchen hygiene compliance and must be within 5 metres of food prep areas. -
Food Prep Sinks:
Required when your menu involves frequent washing of produce. Food prep sink guidelines say these must be separate from dishwashing areas and supplied with both hot and cold water. -
Cleaning Sinks (Dishwashing):
Double- or triple-bowl commercial kitchen sinks are standard for washing, rinsing, and sanitising pots, pans, and utensils. Industrial kitchen sinks are ideal for high-volume operations.
How Many Sinks Are Required in a Commercial Kitchen Setup?
The number of sinks in a commercial kitchen depends on:
- Kitchen size and layout: Larger kitchens or those with multiple prep areas need more sinks to keep up with demand and maintain workflow.
- Menu complexity: More complex menus or high-volume service may require additional food prep or cleaning sinks.
- Staff numbers: More staff means more handwashing stations to prevent bottlenecks and maintain hygiene.
- Regulatory requirements: Local councils may have specific commercial kitchen sink regulations. Always check before finalising your design.
At a minimum, most commercial kitchens in Australia require:
- 1 handwashing sink per food prep area.
- 1 food prep sink (if produce washing is frequent).
- 1 double or triple bowl cleaning sink.
Designing a Commercial Kitchen with Proper Sink Placement
Proper placement of commercial sinks is crucial for smooth operations and compliance. Sinks should be:
- Easily accessible for staff.
- Clearly separated by function (handwashing, food prep, cleaning).
- Installed with splashbacks and draining areas to prevent water damage and contamination.
Choosing the Right Materials and Considering Second Hand Commercial Sinks
-
304 Stainless Steel:
The industry standard for commercial kitchen sinks, 304 stainless steel, is highly resistant to corrosion and easy to clean. -
Second Hand Commercial Sinks:
A budget-friendly option, but always ensure they meet current commercial kitchen sink regulations and are in good condition.
Key Takeaways for Commercial Kitchen Hygiene Compliance
- Always follow handwashing sink standards and food prep sink guidelines to avoid fines and keep your kitchen safe.
- Use only non-porous, corrosion-resistant materials for all commercial sinks.
- Plan your kitchen layout to optimise workflow and meet all commercial kitchen sink requirements.
- Consider second hand commercial sinks for cost savings, but never compromise on compliance or quality.
Don’t Neglect Your Commercial Kitchen Sink Requirements
Choosing the right sink types for commercial kitchens is essential for efficiency, safety and compliance. Always follow commercial kitchen sink requirements and regulations, use high-quality materials like 304 stainless steel, and consider second hand commercial sinks if they meet hygiene standards.
