Pipe Costs by Material
Updated February 24, 2026
Pipe material is one of the biggest cost variables in any plumbing project. PEX can run a whole house for under $500 in materials. Copper for the same house might cost $2,000-$3,000. But material cost is only part of the equation -- labor, fittings, longevity, and code requirements all factor into the real cost of each option.

Pipe material is one of the biggest cost variables in any plumbing project. PEX can run a whole house for under $500 in materials. Copper for the same house might cost $2,000-$3,000. But material cost is only part of the equation -- labor, fittings, longevity, and code requirements all factor into the real cost of each option.
Cost Breakdown
PEX (Cross-Linked Polyethylene)
Material cost: $0.50-$1.50 per foot for 1/2 inch, $1.00-$2.50 for 3/4 inch. PEX is the most cost-effective option for residential supply lines. It's flexible (fewer fittings needed), fast to install (crimp or push-fit connections), and freeze-resistant. Fittings run $0.50-$3 each. Total material cost for a typical home: $300-$800.
Copper
Material cost: $3-$8 per foot for 1/2 inch, $5-$12 for 3/4 inch. Type M (thin wall, residential): $3-$6/ft. Type L (medium wall, commercial): $5-$10/ft. Copper is durable (50+ year lifespan), recyclable, and has a long track record. But it's expensive, requires soldering or press fittings, and is susceptible to theft. Total material cost for a typical home: $1,500-$4,000.
CPVC (Chlorinated PVC)
- Material cost: $0.50-$1.50 per foot.
- CPVC handles hot water (unlike regular PVC) and is approved for supply lines in most areas.
- Solvent-welded connections are permanent and reliable.
- Cheaper than copper but more brittle and not as flexible as PEX.
- Falling out of favor in new construction as PEX gains market share.
PVC / ABS (Drain Lines)
PVC: $0.50-$3 per foot depending on diameter. ABS: similar pricing. These are used for drain, waste, and vent (DWV) lines only -- not supply. Schedule 40 PVC is the residential standard. Fittings are cheap ($0.50-$5 each). Total DWV material cost for a typical bathroom addition: $100-$300.
Cast Iron (Drain Lines)
Cast iron: $5-$15 per foot. Heavy, durable, and extremely quiet (absorbs sound from water flow). Required by code in some multi-story buildings. Used primarily for main drain stacks and horizontal runs where noise reduction matters. More expensive to buy and much more expensive to install than PVC.
Safety Warnings
- Using PVC for hot water supply lines. PVC is for drain lines only -- CPVC or PEX handles hot water.
Pro Tips
- PEX is the clear winner for cost and ease of installation in most residential applications.
- Copper's main advantage is longevity -- 50+ years vs 25-40 for PEX. If you're staying in the home long-term, copper may justify the premium.
- Check local codes before choosing pipe material. Some municipalities restrict PEX or require copper in certain applications.
- Buy pipe in rolls (PEX) or in bulk lengths to save 10-20% over individual sticks.
Mistakes to Avoid
- Using copper for a DIY project when PEX would work and costs 60-80% less.
- Choosing CPVC over PEX in new construction -- PEX is faster to install and more flexible.
- Using PVC for hot water supply lines. PVC is for drain lines only -- CPVC or PEX handles hot water.
- Ignoring fitting costs. Copper fittings and solder add up; PEX push-fit fittings are cheap and fast.
When to Call a Pro
Any work on the main water line, sewer line, or gas line requires a licensed plumber in most jurisdictions. Soldering copper requires skill and a torch -- hire a pro if you're not experienced.
Bottom Line
PEX: $0.50-$2.50/ft -- best value for supply lines. Copper: $3-$12/ft -- premium durability. PVC: $0.50-$3/ft -- standard for drains. Material choice depends on application, code, budget, and how long you plan to stay.
