The Role of Plumbing in Home Renovations: What You Need to Know
Home renovations can breathe new life into your property, but beneath the surface of beautiful finishes and modern layouts lies one of the most critical components of your remodel: the plumbing. Whether you’re upgrading a bathroom, expanding your kitchen, or adding a new laundry room, plumbing in home renovations is an essential consideration. In fact, plumbing systems often dictate what’s possible with your new layout, timelines, and budget. Poor planning or outdated piping can delay projects or lead to costly code violations. Here’s how to do it right—especially if you’re remodeling in Los Angeles, where permit rules and water conservation policies are strict.
Plumbing is the hidden backbone of any home renovation involving water usage. It affects more than just where your sink or shower goes. It influences the structural layout, water pressure, hot water delivery time, and your long-term maintenance costs.
Structural Impact: Relocating fixtures may require rerouting pipes through studs, joists, or concrete slabs.
Permits and Codes: Los Angeles requires permits for all major plumbing modifications to ensure they meet safety and efficiency standards.
Long-Term Savings: Upgrading old or corroded pipes during a remodel can help avoid costly repairs later and improve water quality.
For example, in older Los Angeles homes with galvanized steel pipes, corrosion and reduced flow are common. Renovation is the perfect time to replace these with modern copper or PEX piping.
2025 Plumbing Trends for Home Remodels
In 2025, more homeowners are opting for plumbing upgrades that are both functional and sustainable. Water conservation, smart technology, and design integration are leading the way:
Wall-Mounted Toilets & Vanities: Sleek, modern, and space-saving—perfect for urban homes and minimalist bathrooms.
Tankless Water Heaters: Highly energy-efficient and offer unlimited hot water while saving space.
Touchless Faucets & Smart Showers: Increase hygiene and reduce water waste with customizable settings.
Leak Detection Systems: Connected to your smartphone, these devices automatically shut off water when leaks are detected.
These innovations aren’t just about comfort—they can qualify for rebates through programs like EPA WaterSense or LADWP’s conservation incentives.
What’s Typically Included in Plumbing for Renovations
The scope of plumbing work depends on the nature of your project. Here’s what most remodels include:
Rough-in plumbing: Installing or adjusting supply and drain lines before walls are finished.
Fixture relocation: Moving sinks, toilets, tubs, or appliances often requires new water and drain lines.
New pipe installation: Especially in room additions, ADUs, or when replacing outdated pipes.
Water heater or pressure upgrades: If your current system can’t support added demand.
Final fixture installation and testing: Connecting, sealing, and testing all new fixtures post-inspection.
All of these require precision, knowledge of local codes, and close coordination with contractors and inspectors.

Do I need a permit to move plumbing in Los Angeles?
Yes, any major change to water supply, waste lines, or venting typically requires a plumbing permit in Los Angeles. Unpermitted work can result in failed inspections or fines during resale.
Can I keep existing pipes during a renovation?
If they’re in good condition and up to code, yes—but older homes with galvanized pipes should strongly consider an upgrade to copper or PEX to improve flow and reliability.
What’s the biggest mistake people make during a remodel?
Not involving a licensed plumber early. Plumbers can identify layout conflicts and suggest efficient solutions that save time and rework.
How long does plumbing take during a kitchen or bathroom remodel?
It varies, but rough-in work typically takes 1–3 days, with final installations adding another 1–2 days depending on fixture complexity.
Will my water be shut off during renovation?
Yes, temporarily. We always give advanced notice and aim to restore service same-day whenever possible.
Can I move a toilet or sink to a new location?
Yes, but it requires careful planning and often floor or wall modifications. Drain slope and venting are key considerations.
Should I upgrade my water heater during a remodel?
If it’s more than 10 years old or doesn’t meet your new needs, upgrading to a tankless or high-efficiency model makes financial and environmental sense.
Can I add a second bathroom or laundry room?
Yes, but first a plumber must evaluate whether your main line and venting can handle the additional fixtures without risking backups.
Are there rebates for plumbing upgrades in Los Angeles?
Absolutely. Zenon Plumbing helps homeowners access rebates through LADWP and SoCalGas for high-efficiency toilets, water heaters, and smart irrigation systems.
What’s included in a plumbing inspection for a remodel?
Inspectors check for correct pipe sizing, slope, venting, pressure tests, and backflow prevention. All work must be up to California Plumbing Code.
