Thinking about a kitchen remodel but worried about hidden costs? One of the biggestโand often overlookedโexpenses is how much it costs to move plumbing in kitchen. Whether youโre shifting your sink, relocating the dishwasher, or redesigning your entire layout, plumbing changes can significantly impact your budget. Donโt worryโweโve got you covered with transparent, up-to-date pricing and expert-backed advice to help you plan smarter.
Why Does Moving Kitchen Plumbing Cost So Much?
Moving plumbing isnโt just about rerouting pipesโit involves labor, permits, potential wall or floor demolition, and compliance with local building codes. According to HomeAdvisorโs 2025 data, the average cost to relocate kitchen plumbing ranges from $700 to $3,500, depending on complexity.
Key cost drivers include:
Distance of the move (even a few inches can add expense if walls are involved)
Type of pipes (copper, PEX, or PVC)
Accessibility (finished walls vs. open-concept remodels)
Local labor rates (urban areas like NYC or San Francisco charge 20โ40% more)
๐ก โPlumbing reroutes often uncover outdated systems or code violations,โ says Michael Torres, a licensed master plumber with 18 years of experience in Chicago. โAlways budget 10โ15% extra for unexpected repairs.โ
How Much Does It Cost to Move Specific Kitchen Fixtures?
Not all plumbing moves are equal. Hereโs a breakdown by fixture:
Kitchen Sink
$800 โ $2,500
Most common move; includes drain, supply lines, and venting
Dishwasher
$600 โ $1,800
Requires hot/cold water lines + drain connection near sink
Refrigerator (with water line)
$300 โ $900
Simpler if near existing plumbing; costly if run across kitchen
โ ๏ธ Note: Moving a sink more than 3โ4 feet often requires a new vent stack, which can add $500โ$1,200 alone.
Factors That Affect Your Plumbing Move Cost
1. Distance & Layout Complexity
Moving plumbing within the same wall is far cheaper than crossing the room. Every foot beyond the original location increases labor and material needs.
2. Wall & Floor Access
Open walls during a full remodel? Greatโyouโll save 20โ30%. But if youโre working with finished surfaces, expect drywall repair, painting, and tile work on top of plumbing costs.
3. Pipe Material
PEX tubing: Flexible, cheaper ($0.50โ$2/ft), easy to install
Copper: Durable but expensive ($2โ$8/ft) and labor-intensive
PVC: Common for drains; affordable but not for hot water
Most U.S. municipalities require permits for plumbing alterations. Fees range from $50 to $300, but skipping them risks fines or failed home inspections later.
Step-by-Step: What Happens When You Move Kitchen Plumbing?
If youโre planning this project, hereโs what to expect:
Consultation & Quote A licensed plumber inspects your space, reviews blueprints, and provides a detailed estimate.
Shut Off Water & Drain Lines The main water supply is turned off, and pipes are drained to prevent leaks.
Demolition (If Needed) Cabinets, drywall, or flooring are carefully removed to access pipes.
Reroute Pipes New supply and drain lines are installed using appropriate materials (e.g., ยฝ-inch PEX for water lines, 1ยฝ-inch PVC for drains).
Install Fixtures & Test Sink, faucet, and dishwasher are reconnected. The system is pressure-tested for 15โ30 minutes to check for leaks.
Inspection & Restoration A city inspector may verify code compliance. Then, walls/floors are repaired and finished.
โ Pro Tip: Schedule plumbing work before new cabinets or countertops are installed to avoid costly rework.
DIY vs. Hiring a Pro: Is It Worth the Risk?
While YouTube makes plumbing look simple, kitchen plumbing involves pressurized water lines, drainage slopes, and venting rules that require expertise.
DIY Risks: Leaks, mold, failed inspections, voided home insurance
When DIY Might Work: Minor moves (<1 ft) with accessible pipes and PEX experience
According to the National Association of Home Builders (NAHB), 87% of plumbing-related insurance claims stem from DIY errors. Unless youโre certified, hire a licensed plumberโlook for one with:
State license & liability insurance
4.8+ rating on Angi or HomeAdvisor
At least 5 years of kitchen-specific experience
How to Save Money Without Sacrificing Quality
Keep Fixtures Close Stay within 2โ3 feet of original plumbing to avoid new vents or long pipe runs.
Bundle with Other Renovations Combine plumbing work with flooring or cabinet installs to reduce labor duplication.
Get Multiple Quotes Compare 3โ4 detailed estimates. Beware of bids that seem too lowโthey may omit permits or use subpar materials.
Choose PEX Over Copper Youโll save 30โ50% on materials without compromising performance.
FAQ: Your Top Questions Answered
Q1: How much does it cost to move a kitchen sink 2 feet?
A: Typically $900โ$1,800. This includes rerouting hot/cold lines, drain, and vent if needed. Costs rise if walls must be opened or floors cut.
Q2: Can I move plumbing to a kitchen island?
A: Yes, but itโs one of the most expensive moves ($2,500โ$5,000+). Islands often require new floor drains, supply lines, and ventingโsometimes involving subfloor work.
Q3: Does homeowners insurance cover plumbing relocation?
A: No. Insurance covers damage (e.g., burst pipes), not voluntary upgrades. However, proper permits protect your resale value.
Q4: How long does kitchen plumbing relocation take?
A: Simple moves: 1โ2 days. Full reroutes with wall work: 3โ5 days. Delays can occur if old pipes (e.g., galvanized steel) need full replacement.

A: Yes! Watch for:
Asbestos or lead paint abatement (in homes built before 1978)
Upgrading to code-compliant shutoff valves
Reconnecting garbage disposals or water filters
Q6: Can I move plumbing myself and just hire someone to inspect?
A: Technically yes in some areas, but most jurisdictions require licensed plumbers to pull permits. DIY work often fails inspection due to improper slope or venting.
