If you’ve just bought a new refrigerator with an ice maker or water dispenser—or you’re upgrading your kitchen—you’re probably asking: “How much does it cost to plumb a water line for a refrigerator?” You’re not alone. Many homeowners face this exact question, balancing the desire for convenience against budget concerns. Whether you’re considering a DIY approach or hiring a pro, understanding the true how to plumb a water line for a refrigerator cost can save you time, stress, and hundreds of dollars.
How Much Does It Cost to Plumb a Water Line for a Refrigerator?
The average cost to install a refrigerator water line in the U.S. ranges from $70 to $250, depending on labor rates, materials, and distance from the nearest water source. According to HomeAdvisor’s 2025 data, most homeowners pay around $150 for a standard installation by a licensed plumber.
But costs can vary widely:
- DIY kits: $20–$50 (plus your time)
- Professional installation: $100–$250
- Complex setups (e.g., running lines through walls or floors): up to $500+
💡 Pro Tip: If your fridge is within 6 feet of an existing cold water line (like under the sink), installation is usually straightforward and affordable.
What Factors Affect the Cost?
Several variables influence your total expense:
1. Distance from Water Source
The closer your fridge is to a cold water supply (typically under the kitchen sink), the lower the cost. Every extra foot of tubing adds material and labor.
2. Type of Tubing Used
- Plastic (PEX or polyethylene): $0.20–$0.50/ft — flexible, easy to install, common for DIY.
- Copper: $1–$3/ft — durable but requires soldering; best left to pros.
- Braided stainless steel: $10–$20 per 25-ft coil — kink-resistant and long-lasting.
3. Wall or Floor Obstructions
Running lines through cabinets is simple. But if you need to drill through drywall, tile, or flooring, expect higher labor fees.
4. Local Labor Rates
Plumbers in urban areas like New York or San Francisco may charge $100+/hour, while rural areas average $50–$75/hour.
DIY vs. Hiring a Professional: Which Is Better?
Let’s break it down:
| Factor | DIY | Professional |
|---|---|---|
| Cost | $20–$50 | $100–$250+ |
| Time | 1–3 hours | 30–90 minutes |
| Skill Required | Basic plumbing knowledge | Licensed expertise |
| Risk | Leaks, voided warranty | Guaranteed work, code-compliant |
| Best For | Handy homeowners near water source | Complex installs or no experience |
⚠️ Warning: Some refrigerator warranties are voided if installed incorrectly. Always check your manual first.
According to the U.S. Department of Energy, improper water line connections are a leading cause of kitchen water damage—accounting for nearly 10% of household insurance claims related to appliances.

Step-by-Step: How to Install a Refrigerator Water Line (DIY)
Only attempt this if your fridge is near an existing cold water shutoff valve (usually under the sink).
Tools & Materials Needed:
- 1/4-inch plastic or copper tubing (25 ft recommended)
- Saddle valve or push-fit tee connector (avoid saddle valves—they’re outdated and prone to leaks)
- Adjustable wrench
- Tube cutter
- Teflon tape
- Refrigerator water line kit (often includes fittings)
Steps:
- Turn off the main water supply and open the nearest faucet to relieve pressure.
- Locate the cold water line under the sink (usually a 3/8″ or 1/2″ pipe).
- Install a push-fit tee connector (e.g., SharkBite) onto the cold line. Do not use piercing saddle valves—they violate modern plumbing codes in many states.
- Cut the tubing to length (measure from tee to fridge inlet, adding 2 extra feet for flexibility).
- Attach one end to the tee, the other to the fridge’s water inlet (usually at the back bottom).
- Turn water back on, check for leaks, and flush the line by dispensing 2–3 gallons of water to remove debris.
- Plug in the fridge and test the ice maker/water dispenser.
✅ Safety Note: Use only tubing rated for potable (drinkable) water. Never use garden hose or non-approved plastic.
Common Mistakes to Avoid
- Using a saddle valve: These puncture the main line and often leak over time. Modern codes discourage them.
- Skipping the shut-off valve: Always install an inline shut-off near the fridge for easy maintenance.
- Kinking the tubing: Leave slack and avoid sharp bends—especially with plastic lines.
- Ignoring local codes: Some municipalities require permits or inspections for new plumbing lines.
How to Save Money Without Sacrificing Safety
- Buy a quality kit: Brands like GE, Whirlpool, or SharkBite offer reliable DIY kits (~$30).
- Use PEX tubing: It’s cheaper than copper and doesn’t require soldering.
- Watch tutorial videos: YouTube channels like Home RenoVision DIY offer clear, code-compliant guides.
- Ask your appliance retailer: Some stores (e.g., Best Buy, Lowe’s) include basic water line hookups with delivery for $50–$99.
FAQ Section
Q1: Can I install a fridge water line myself?
A: Yes—if your fridge is near an existing cold water line and you’re comfortable with basic tools. Avoid complex runs through walls unless experienced.
