A bathroom remodel is exciting. New tile, a new vanity, a better shower, and updated fixtures can completely change the look and feel of your home.

But before you start picking out finishes, don’t forget about what’s behind the walls.

Your bathroom’s plumbing plays a major role in determining what you can change, where new fixtures can go, and whether your remodel will work the way you expect. Planning for the plumbing early can help prevent unexpected problems, delays, and additional costs later.

Here are six things every homeowner should know before remodeling a bathroom.

1. Understand Your Existing Plumbing Layout

Before moving a toilet, sink, shower, or tub, it’s important to understand where your existing plumbing is located.

Your plumber may need to consider:

• Water supply lines
• Drain lines
• Plumbing vents
• The location of the toilet drain
• Existing pipe materials and condition

Some fixture locations are much easier to change than others. Understanding the existing layout before demolition can help you determine what is realistic for your remodel.

2. Check for Leaks and Plumbing Problems First

A bathroom remodel is not the time to discover that you have a leaking pipe or deteriorated plumbing behind the wall.

Before closing up walls or installing new finishes, have your plumbing inspected for issues such as:

• Leaking pipes
• Corrosion
• Damaged supply lines
• Drain problems
• Outdated or deteriorated plumbing

Taking care of these problems early can help protect your new flooring, walls, cabinets, and fixtures.

3. Plan Your New Fixtures With Plumbing in Mind

Choosing a new toilet, shower, tub, or sink isn’t just about appearance.

Each fixture has specific plumbing requirements.

For example, if you’re installing a new shower, your plumber may need to consider water supply connections, the shower valve, drain location, and available water pressure.

Planning these details before purchasing fixtures can help prevent the frustrating situation of buying something that doesn’t work with your existing plumbing.

4. Think Carefully Before Moving Fixtures

Moving a sink is one thing. Moving a toilet can be much more involved.

Relocating plumbing fixtures may require changes to water lines, drain lines, and venting. Depending on the layout of your bathroom and the location of the existing plumbing, moving a fixture can significantly increase the scope and cost of the remodel.

If you’re considering changing the location of your toilet, shower, or sink, talk to a plumber before construction begins.

It may be possible, but knowing what’s involved ahead of time can help you plan your budget and timeline.

5. Don’t Forget About Plumbing Vents

Venting is an important part of your bathroom’s plumbing system.

Properly installed plumbing vents help maintain the pressure within your drainage system and protect the water seals in your traps. Without proper venting, you can experience slow drains, unpleasant odors, or other drainage problems.

If you’re changing the location of a fixture, your existing venting may need to be evaluated or modified.

6. Check Permit and Code Requirements

Depending on the scope of your bathroom remodel and where you live, plumbing work may require permits and inspections.

Requirements can vary based on the project and local jurisdiction, so it’s important to understand what applies before work begins.

A professional plumber can help you understand when plumbing work may require additional planning or permitting.
