Should You Replace Old Plumbing During a Remodel?

August 7, 2026

A kitchen or bathroom remodel is an exciting opportunity to update your home's style, improve functionality, and increase its value.

But while you're choosing cabinets, countertops, tile, and fixtures, there's one important question many homeowners overlook:

Should you replace your old plumbing while everything is already opened up?

In many cases, the answer is yes.

A remodel provides rare access to the plumbing behind your walls. Replacing aging pipes, outdated fixtures, or worn plumbing components during construction can help prevent expensive repairs after your project is complete.

At TLH Plumbing, we work with homeowners and contractors throughout Middle Tennessee to ensure remodeling projects are built on reliable plumbing systems that will last for years to come. Whether you're updating a single bathroom or completely renovating your kitchen, our experienced plumbers can help you make smart decisions before the walls are closed back up.

TLH Plumbing provides remodel plumbing services that include relocating water and drain lines, upgrading shower valves, installing fixtures, adjusting venting, and replacing water heaters when needed.

When Should You Replace Old Plumbing?

Not every remodel requires a full repipe, but several signs indicate it may be time to upgrade your plumbing.

Consider replacing your plumbing if:

Your home is several decades old.
You've experienced recurring leaks.
Water pressure has gradually declined.
Pipes show signs of corrosion or rust.
You're already opening walls during the remodel.
You're changing the layout of your kitchen or bathroom.

Replacing plumbing while walls are already exposed is typically much more cost-effective than opening finished walls a few years later to repair a hidden leak.

Remodeling Is the Perfect Time to Upgrade

Many remodeling projects involve more than cosmetic improvements.

You may be:

Moving a kitchen sink to a new island
Installing a larger shower
Relocating a bathtub
Adding a double vanity
Installing a utility sink
Upgrading appliances

Each of these changes often requires adjustments to water supply lines, drain lines, venting, or shut-off valves.

TLH Plumbing works alongside homeowners and contractors to ensure every plumbing connection is installed correctly before the finishing work begins. Their remodel services include moving supply and drain lines, dishwasher and refrigerator water line hookups, shower and tub valve upgrades, vanity and toilet installation, laundry relocations, and drain rework as needed.

Hidden Plumbing Problems Are Easier to Fix During a Remodel

One of the biggest advantages of remodeling is discovering issues you couldn't see before.

Once walls or floors are opened, plumbers often find:

Small leaks
Corroded pipes
Aging shut-off valves
Improper drain slopes
Outdated plumbing materials
Slow or partially clogged drain lines

Addressing these problems now helps avoid future water damage and protects your investment in new flooring, cabinets, drywall, and tile.

Should You Replace Your Water Heater Too?

If your water heater is nearing the end of its lifespan, remodeling is an excellent time to consider replacing it.

Many homeowners upgrading their bathrooms choose larger showers, soaking tubs, or multiple shower heads that place greater demand on their hot water system.

TLH Plumbing installs and services electric, natural gas, and tankless water heaters throughout Middle Tennessee. If your current unit is leaking, experiencing repeated issues, or no longer keeping up with your family's hot water needs, their team can recommend the best replacement while your remodel is underway.

Benefits of Replacing Plumbing During a Remodel

Upgrading older plumbing while remodeling offers several long-term benefits:

Reduce the risk of future leaks
Improve water pressure
Increase plumbing efficiency
Meet current plumbing codes
Support new fixtures and appliances
Protect your remodeling investment
Gain peace of mind knowing everything behind the walls is in excellent condition

Although replacing plumbing adds to the initial project cost, it often saves homeowners significant money by preventing unexpected repairs after the remodel is finished.
