Why Is a Hand Sink For Food Truck Required by Law?
A hand sink for food truck is legally required because handwashing is the single most effective way to prevent the spread of bacteria and foodborne illnesses. According to public health data, proper handwashing can reduce contamination risks by over 50% in food handling environments.
Food safety regulations in the U.S. are guided by agencies such as the FDA and local health departments. They follow guidelines from institutions like the Food Code, which emphasizes that employees must have convenient access to a designated handwashing station at all times.
For background on the importance of hand hygiene in food service, see this authoritative source on Wikipedia:

Most health departments will immediately fail a food truck inspection if:
- There is no dedicated hand sink
- The sink is blocked or used for dishes
- Hot water is not available
- No soap or paper towels are present
A hand sink is not optional — it is essential.
What Are the Requirements for a Hand Sink For Food Truck?
Although specific rules vary by state and county, most U.S. health departments require the following:
✅ Hot and cold running water
✅ A mixing faucet
✅ Soap dispenser
✅ Paper towel holder (not cloth)
✅ A wastewater tank
✅ Separate from dishwashing sinks
Basic Size Requirements (Typical Range)
| Component | Standard Minimum |
|---|---|
| Sink bowl width | 9–12 inches |
| Sink depth | 5–6 inches |
| Fresh water tank | 20–40 gallons |
| Wastewater tank | 30–50 gallons |
| Water temperature | Minimum 100°F (38°C) |
These standards ensure that food handlers can wash hands properly for at least 20 seconds per wash, which is the CDC recommendation.
💡 Pro Tip: Some counties require a separate sink for dishes and utensils, so never try to combine them.
Where Should a Hand Sink Be Installed in a Food Truck?
Placement is just as important as the sink itself.
The hand sink for food truck must be:
- Easily accessible to employees
- Located in a food preparation zone
- Unobstructed at all times
- Away from raw food contact surfaces
Best Placement Ideas
✔ Near the food prep counter
✔ Next to the service window
✔ At the entrance of the prep area
🚫 Under storage
🚫 Behind equipment
🚫 Inside cabinets
If staff have to walk far to wash hands, inspectors may consider it non-compliant.
Optimal placement improves workflow and increases hygiene compliance.
How Much Does a Hand Sink For Food Truck Cost?
Pricing depends on materials, size, and features. Here’s a realistic breakdown:
| Type | Average Cost |
|---|---|
| Basic stainless steel | $150–$300 |
| With foot pedal | $300–$550 |
| NSF certified | $400–$900 |
| Custom-built | $1,000+ |
Additional costs to consider:
- Plumbing: $150–$400
- Water tank setup: $100–$300
- Installation labor: $200–$500
💵 Total average investment: $500 – $1,500 depending on your setup.
While this may seem high, it is minor compared to:
- Fines for non-compliance
- Losing your license
- Shutting down your truck
A functional hand sink is an investment in long-term success.

What Type of Sink Is Best: Foot Pedal or Hand Faucet?
Many food truck owners ask this exact question.
Here’s a simple comparison:

|---|---|---|
| Hygiene | Excellent | Good |
| Cost | Higher | Lower |
| Ease of use | Very Easy | Easy |

Foot pedal systems are strongly preferred because they maintain hands-free operation — reducing contamination risk.
