The Top Plumbing Upgrades That Add Value to Your Home

When most homeowners think about boosting home value, they picture kitchen remodels, new flooring, or fresh paint. But one of the most overlooked—yet high-impact—improvements you can make is upgrading your plumbing system. Modern plumbing upgrades not only improve daily comfort and efficiency, but they also significantly enhance your home’s resale value.

For buyers, a home with updated plumbing represents safety, lower maintenance costs, and modern convenience. For homeowners, it means fewer breakdowns, better water quality, lower utility bills, and a higher market value.

Below are the top plumbing upgrades that offer the best return on investment (ROI) and elevate the long-term value of your home.

1. Install a Tankless Water Heater

Tankless (on-demand) water heaters are one of the most desirable plumbing upgrades among today’s buyers.

Why it adds value

• Endless hot water

• Up to 30–40% more energy-efficient than tank systems

• Saves space

• Lasts 20+ years

• Increases home energy rating

Homebuyers love tankless systems because they eliminate the annoyance of running out of hot water and help lower monthly energy bills.

Average cost: $2,500–$4,500

ROI: High

2. Replace Old Pipes With Modern Piping (PEX or Copper)

If your home is more than 30–40 years old, your plumbing pipes may be outdated. Galvanized steel, polybutylene, and old copper pipes can cause leaks, low water pressure, and water discoloration.

Benefits of repiping

• Eliminates hidden leaks

• Improves water pressure

• Protects from major water damage

• Boosts buyer confidence

• Enhances water quality

• Increases long-term property value

Best modern materials

• PEX: Flexible, durable, affordable

• Copper: Long-lasting, premium appearance

ROI: Very high—buyers strongly prefer homes with new pipes.

3. Install Water-Saving Fixtures

Eco-friendly upgrades are extremely appealing to today’s buyers. Water-efficient fixtures reduce waste, cut utility bills, and make the home feel more modern.

Top fixtures to upgrade

• Low-flow toilets (up to 20,000 gallons saved per year)

• Low-flow faucets

• High-efficiency shower heads

• Touchless faucets

These upgrades make a noticeable difference in monthly utility costs—and buyers recognize that value immediately.

4. Add a Whole-Home Water Filtration System

Clean, great-tasting water is a major selling point. A whole-home water filtration system will filter water at the source, providing healthier, clearer water throughout your home.

Benefits

• Removes chlorine, sediment, and contaminants

• Extends the life of appliances

• Reduces scale buildup

• Provides soft, high-quality water

• Increases home appeal and buyer confidence

ROI: Moderate to high

In areas with hard water, this upgrade is especially desirable.

5. Bathroom Plumbing Upgrades

Bathrooms sell houses. Modernizing the plumbing inside your bathrooms can dramatically enhance property value.

Top value-boosting upgrades

• New faucets and shower fixtures

• Dual-flush or low-flow toilets

• Rainfall or multi-stream shower systems

• Heated bidet seats

• Upgraded vanity plumbing

• Luxury finishes (matte black, brushed gold, stainless steel)

Buyers prioritize updated bathrooms, and these improvements make your home feel fresh and luxurious.

6. Kitchen Sink & Faucet Upgrades

A modern kitchen is a huge value add—and plumbing plays a major role.

High-value kitchen plumbing upgrades

• Deep stainless steel or granite composite sink

• Pull-down or touchless faucet

• Garbage disposal upgrade

• Water filtration at the sink

• Pot fillers for premium kitchens

These upgrades improve functionality and elevate the look and feel of your kitchen—one of the most important rooms for resale.

7. Add a Smart Leak Detection System

Smart home plumbing devices are increasingly popular. A whole-home leak detection system monitors water flow and automatically shuts off the supply to prevent flooding.

Why buyers love this

• Prevents thousands of dollars in damage

• Provides instant alerts via mobile app

• Protects appliances and flooring

• Reduces insurance risks

This small investment yields huge protection—and makes listing your home more competitive.

8. Install a Sump Pump or Upgrade an Old One

If your home has a basement, a sump pump is essential.

Benefits

• Prevents flooding

• Reduces mold and moisture problems

• Protects foundation integrity

• Boosts long-term home safety

Adding a battery backup system increases reliability—and value.

9. Upgrade Outdoor Plumbing

Outdoor plumbing is often overlooked, but it can boost your home’s functionality and appeal.

High-value outdoor upgrades

• Frost-proof hose bibbs

• Irrigation system improvements

• Outdoor kitchens or wet bars

• Tankless water heater for outdoor showers

• Drainage system upgrades

These upgrades add convenience and reduce maintenance for future homeowners.

10. Add a Water Softener System

Hard water can cause mineral buildup in pipes, shorten appliance lifespan, and leave stains on fixtures. Installing a water softener greatly improves water quality.

Benefits

• Extends plumbing system life

• Reduces scale buildup

• Improves efficiency of water heaters

• Enhances skin and hair comfort

• Improves appliance longevity

Homes with soft water systems often sell for more and attract more buyers.

Final Thoughts: Plumbing Upgrades Are a Smart Investment

Whether you plan to sell soon or just want to future-proof your home, plumbing upgrades offer some of the best ROI of any renovation. They improve safety, efficiency, comfort, and marketability—making your home more appealing to buyers and more enjoyable for your family.
