Remodeling Your Kitchen or Bath Requires Updated Plumbing
Residential Plumbing Remodels in New Braunfels and surrounding communities for homes replacing sinks, tubs, showers, or appliances
Night & Day Plumbing handles residential plumbing remodels that update your water lines, drain routing, and fixture connections during kitchen and bathroom renovations. When you tear out old cabinets or remove a bathtub, the plumbing underneath may no longer align with the new layout, or it may be outdated galvanized steel or corroded copper that needs replacement before you install modern fixtures.
This service includes relocating supply lines to match new sink or appliance positions, rerouting drain lines when a toilet or shower moves to a different wall, and installing shutoff valves and proper venting that meet current building codes. Older homes often have undersized pipes or configurations that cannot handle the flow demands of new rain showerheads or tankless water heaters, so upgrading during a remodel prevents pressure drops and drainage problems after construction is complete.
If you are planning a renovation and need plumbing updates mapped out before demolition begins, reach out to discuss the scope and timing of the plumbing portion of your project in New Braunfels, Schertz, Boerne, and surrounding areas.
What Happens During a Residential Plumbing Remodel
The work begins with an assessment of your current plumbing layout and the new fixture locations outlined in your remodel plans. You will see which existing pipes can remain, which sections must be capped or removed, and where new lines need to run through walls or floors to reach relocated sinks, dishwashers, or bathtubs.

After the plumbing is roughed in and inspected, you will notice that all water connections align precisely with the placement of your new cabinets and fixtures, drain lines slope correctly to prevent standing water, and shutoff valves are accessible behind or beneath each fixture so future repairs do not require cutting into finished walls. Night & Day Plumbing LLC coordinates with your contractor or directly with you to complete rough-in work before drywall goes up and finish work once cabinetry and tile are installed.
The scope does not include electrical work, tile setting, or cabinet installation, but it does cover pressure testing of new supply lines and verification that all drain connections are watertight and vented according to local plumbing code. If your remodel includes moving a gas line for a range or relocating a water heater, those changes are planned as part of the same project to avoid redundant wall openings.
Questions Homeowners Ask About Plumbing Remodels
Remodel projects raise specific questions about timing, compatibility with older systems, and what needs to be updated to support new fixtures.
What happens if the new sink is three feet from where the old one was?
The supply lines and drain are extended or rerouted through the wall or floor, and the old connections are capped and left in place or removed depending on access and code requirements.
How do you know if existing pipes need to be replaced during a remodel?
If the visible sections show corrosion, pinhole leaks, or are made of outdated materials like polybutylene or galvanized steel, replacement is recommended to avoid failures behind new finishes.
When does the plumber need to be on site during a renovation?
Rough-in work happens after demolition and framing but before insulation and drywall, and finish work occurs after tile and cabinets are set but before the final walkthrough.
Why does a bathroom remodel sometimes require a larger drain line?
Modern low-flow toilets and code updates may require a three-inch drain instead of older two-inch cast iron, and adding a second sink or a separate shower and tub can exceed the capacity of the original waste line.
What is included in the plumbing portion of a kitchen remodel in San Antonio and surrounding areas?
The work covers relocating or adding supply lines for the sink, dishwasher, refrigerator, and any pot filler or instant hot water dispenser, plus updating the drain and vent system to match the new layout and installing shutoff valves at each connection point.
If you are beginning a remodel and need a plumbing plan that accounts for fixture placement and code compliance, schedule a consultation with Night & Day Plumbing LLC to review your layout and establish a timeline that keeps the project moving without delays.
