The Cost and Process of Moving Plumbing During a Remodel

Remodeling a kitchen, bathroom, or laundry room can completely transform the look and functionality of your home. While new tile, countertops, cabinets, and lighting are fun parts of the design process, one of the biggest decisions you will face is whether to move the plumbing. Relocating sinks, toilets, showers, or appliances changes the layout and flow of a room, but it also adds complexity, cost, and extra steps to the project.

Understanding the cost and process of moving plumbing during a remodel helps you plan realistically and avoid unexpected expenses. In this guide, you will learn why homeowners choose to move plumbing, what impacts cost, how the plumbing relocation process works, and when hiring professionals like Advanced Heat, AC, & Plumbing is essential.

Why Homeowners Choose to Move Plumbing

Moving plumbing is sometimes necessary to achieve the layout or function you want from a remodel. Here are the top reasons homeowners decide to relocate their plumbing:

1. A More Functional Layout

Older home layouts are often inefficient. Moving a sink or toilet to a better location can open up floor space, improve workflow, and create a modern design.

2. Adding New Fixtures

If you want a double vanity, a kitchen island sink, or a walk in shower, the plumbing must often be rerouted to support the new fixture locations.

3. Fixing or Replacing Old Plumbing

During renovations, homeowners often discover corroded pipes or outdated materials. Relocating fixtures gives plumbers easier access to replace or upgrade these lines through professional plumbing services.

4. Improving Accessibility

Relocating plumbing fixtures can provide the space needed for wider walkways, barrier free showers, or wheelchair accessibility.

5. Changing the Room’s Purpose

Turning a half bath into a full bath or converting a closed kitchen into an open layout may require plumbing relocation.

Factors That Influence the Cost of Moving Plumbing

The cost of moving plumbing varies depending on several important factors. Understanding these will help you budget for your remodel more accurately.

1. Type of Fixture Being Moved

Some fixtures are far easier to move than others.

• Sinks: Usually the least expensive to move.
• Showers and tubs: More complex due to drain size and waterproofing needs.
• Toilets: Typically the most expensive because they require large drains and precise installation.

2. Distance of the Move

A small shift of a few inches is simple. Moving a fixture several feet or to a new wall significantly increases labor and material costs.

3. Access to Existing Plumbing

Plumbing in crawl spaces or basements is easier to access. Plumbing inside concrete slabs or finished walls is more time consuming to relocate.

4. Structural Restrictions

If relocating plumbing requires cutting into load bearing walls or floors, that raises the cost.

5. Age and Condition of Existing Pipes

Old, rusty, or undersized pipes may need full replacement. Upgrading these components is smart but increases cost.

6. Local Codes and Permits

Your remodel must follow Tennessee plumbing codes. Permits add cost but ensure safety and compliance. Skilled plumbers through Advanced Heat, AC, & Plumbing handle these requirements.

7. Labor Costs

Labor depends on the complexity of the work, the level of expertise needed, and the time required to complete the project.

Cost Breakdown of Common Plumbing Moves

Costs vary, but here is a general idea of what to expect when relocating different fixtures.

1. Moving a Sink

Moving a sink is usually straightforward. It may involve adjusting supply lines, drain pipes, and venting. Sink relocations are common in kitchen remodels and often remain moderate in cost unless the home is on a concrete slab.

2. Moving a Toilet

Toilets are more expensive to move because the large drain line and vent stack must be adjusted. Toilets depend heavily on gravity, so their placement is precise. This is typically one of the higher cost plumbing moves.

3. Moving a Shower or Bathtub

Shower and tub moves involve:

• Rerouting hot and cold lines
• Installing or modifying a drain
• Ensuring waterproofing
• Adjusting framing

Many homeowners choose to add rainfall showerheads or body sprayers, which may require upgraded supply lines that can be handled through bathroom plumbing upgrades.

4. Moving Laundry Connections

Relocating a washer requires rerouting supply lines, venting the drain correctly, and adjusting the drain height. If the dryer is gas powered, the gas line may also need relocation.

The Step by Step Process of Moving Plumbing

Moving plumbing is precise work requiring professional skill. Here is how the process typically unfolds.

Step 1: Initial Consultation and System Inspection

A licensed plumber evaluates your current plumbing system, fixture placement, pipe materials, and overall remodel plan. This step determines feasibility, identifies hidden problems, and helps calculate costs.

Step 2: Creating a New Plumbing Layout

Once the inspection is complete, the plumber designs a new plumbing layout. This includes:

• Pipe routes
• Drain slopes
• Vent placements
• Shutoff valve locations
• Fixture measurements

This layout ensures your renovation meets local code requirements and functions efficiently.

Step 3: Securing Permits

Any work involving plumbing relocation requires permits. Your contractor or plumber secures the necessary permits before work begins to keep the remodel compliant and safe.

Step 4: Opening Walls, Floors, or Ceilings

Access is required to reroute pipes. This may involve removing sections of drywall, cutting floors, or opening ceiling areas. Professional plumbers work carefully to minimize damage and dust.

Step 5: Rerouting Water Supply and Drain Lines

This is the most technical step. Plumbers:

• Install new supply lines
• Reroute or extend drain pipes
• Adjust venting
• Replace damaged or outdated parts
• Install new shutoff valves

If hidden leaks or failing pipes are found, the plumber may recommend additional repairs for long term reliability.

Step 6: Testing and Inspection

After pipe installation, the system is pressure tested to check for leaks. Once it passes testing, a building inspector reviews the work to ensure code compliance.

Step 7: Closing the Walls or Floors

Once the plumbing passes inspection, contractors close the drywall, flooring, or ceiling. This stage prepares the room for tile, paint, cabinets, or fixtures.

Step 8: Fixture Installation and Final Testing

When the remodel is nearing completion, your plumber returns to install:

• Faucets
• Sinks
• Toilets
• Showers and tubs
• Valve trim
• Drain assemblies

A final test ensures proper pressure, drainage, and overall performance. If any future service is needed, emergency support is available through 24 hour plumbing repair.

When Moving Plumbing Is Worth the Investment

While plumbing relocation adds cost and complexity, it can offer major benefits.

Moving plumbing is worth it when:

• Your current layout is difficult to use
• You want an open kitchen design
• You are upgrading to a luxury shower system
• You need more space for accessibility
• You are replacing severely outdated plumbing
• The new layout significantly improves functionality

More functional spaces often improve daily comfort and raise property value.

Common Mistakes Homeowners Make When Moving Plumbing

Avoiding these mistakes can save you time, stress, and unexpected expenses.

1. Underestimating Costs

Many homeowners fail to account for structural changes, code requirements, and the time needed for plumbing rerouting.

2. Attempting DIY Plumbing Moves

Plumbing work requires experience and precision. Improper installation can lead to leaks, mold, and major repairs. Hiring trained technicians through professional plumbing services ensures safe and accurate work.

3. Ignoring Water Pressure Requirements

Modern fixtures such as rainfall showerheads or body sprays need adjusted or upgraded supply lines.

4. Poor Venting

Improper venting can cause gurgling drains, sewer odors, and slow water flow.

5. Forgetting Future Access

Always include access points for shutoff valves and maintenance.

6. Not Upgrading Old Pipes During the Remodel

If pipes are more than two decades old, it is cost effective to replace them during your renovation.

FAQs About Moving Plumbing During a Remodel

1. Is moving plumbing expensive?

Costs vary depending on fixture type, distance, and accessibility. Toilets and showers are the most expensive to move.

2. How long does plumbing relocation take?

3. Can I move plumbing myself?

No. Relocating plumbing requires permits, inspections, and licensed expertise.

4. Will my remodel require new pipes?

If your pipes are older, rusted, or undersized, it is smart to replace them during the remodel.

5. What if my home is built on a concrete slab?

Plumbing moves are more complex on slabs and may require concrete cutting.

Conclusion

Moving plumbing during a remodel can significantly improve layout, convenience, and the long term value of your home. While it adds cost and requires professional expertise, the transformation it brings to kitchens, bathrooms, and laundry rooms is often worth the investment.
