Cost GuideUpdated June 29, 2026
Modern kitchen remodels in Romeoville often focus on function as much as style. For practical cooks and busy families, a pot filler above the stove or an extra prep sink can make life easier. Adding either of these features takes more than picking a fixture at the store. The job involves new water lines, careful planning, and the right permits. Understanding what's required helps you budget and avoid surprises.
Why Adding New Fixtures Requires Professional Plumbing
Running a new water line to a spot where there wasn't one before is never as simple as drilling a hole and hooking it up. In our part of Illinois, most kitchens are designed with the main supply lines and drains concentrated on one side of the room. Bringing water to a stove or island usually means opening up walls or cabinets, sometimes working around existing gas lines or electrical.
We see this a lot in Romeoville's mix of homes, from newer subdivisions to older houses that were built before open concept kitchens became common. Newer builds often have PEX or copper lines, while older ones might still rely on CPVC or mixed materials. Each comes with its own challenges for tapping in or extending lines.
What Goes Into Adding a Pot Filler
A pot filler installs above your stove, letting you fill pans without lugging water from the sink. That sounds simple, but a few pieces need to line up for a safe, code-compliant result:
- Water source: A cold water line is routed from your main supply, sometimes through finished walls or floors.
- Valve placement: Check local code for backflow prevention. Many fixtures come with built-in check valves, but installation still needs to prevent contamination.
- Pipe material: Copper or PEX are both common in Romeoville homes. We check accessibility and how it ties into your existing system.
- Access for repairs: Concealed lines should have shut-offs in an accessible spot. We avoid burying connections where a leak could go unnoticed.
The most substantial cost drivers are how far we need to run pipe and whether demolition is needed. If your kitchen is on a slab or has minimal basement access, costs go up since concrete may need to be cut. Where homes are built on crawlspaces or basements, the job is faster and less invasive.
Adding a Second Sink at an Island or Prep Station
Many kitchens in the southwest suburbs are getting larger islands, and a second sink for prep or bar service is more popular than ever. Unlike a pot filler, a second sink needs both hot and cold water lines and a drain.
This means tying into your existing water lines and extending a new branch for waste water. Depending on your home's plumbing layout, we might run new P-traps and vent lines, especially in homes where the original plumbing didn't plan for island or peninsula sinks. If the kitchen is above a finished basement, we plan carefully to protect ceilings and finishes. Foundation type also matters, Romeoville's clay soils and moderate water table make slab work more involved.
Permits are required in most cases. We also test for leaks and proper drainage before closing anything up. Sometimes, an undersized or aging drain needs to be upgraded to handle the extra sink, so we'll check that too. For homes with older pipes or frequent clogs, we might suggest drain cleaning or even pipe repair and repiping before moving forward.
Steps for a Safe and Reliable Installation
- Plan fixture placement and height to match your needs (pot fillers typically go 12-18 inches above burners).
- Map water line paths and confirm pipe material compatibility with current system.
- Shut off the main water supply and protect nearby finishes before starting any wall cuts.
- Install new shut-off valves near the new fixture for easy future maintenance.
- Pressure test all connections before restoring water and closing up walls or cabinets.
- For sinks, check venting and tie drain lines into the main branch at the right slope to prevent backups.
We often coordinate with your general contractor or cabinet installer to keep the project moving. If your project also involves new appliances, garbage disposal, or a water heater, we can handle those connections too.

Common Issues That Affect Cost in Romeoville
Romeoville's housing stock varies in age and building style. In older neighborhoods, it's common to find a mix of copper, galvanized, and sometimes CPVC supply lines. Tying in new work means confirming the condition and code of the original pipes. Sometimes, we find pipes that are corroded, undersized, or even partially clogged from years of mineral buildup due to our hard water. This affects both how we connect new lines and the recommended fixture types.
Homes built slab-on-grade without a crawlspace or basement may need more extensive work, since all pipes run through concrete. In those cases, labor and repair to flooring or cabinetry makes up a notable part of the project cost. Lastly, if your remodel plans trigger new code requirements, like pressure balancing or upgraded shut-offs, that can add to the estimate.
Romeoville's cold winters are another concern. Any lines running along exterior walls need insulation to prevent freezing. We also consider freeze-thaw cycles when sealing wall or floor penetrations. If you have a history of basement seepage or backups, now might be the time for sump pump upgrades or leak detection before expanding water lines.
What to Budget for Kitchen Water Line Upgrades
It's common for Romeoville homeowners to ask for a rough price over the phone, but real costs depend on how your kitchen is built and what's behind the walls. Adding a pot filler is usually less costly than a second sink, since there's no need for drainage or hot water. If the water source is close by and walls are open, labor is lower. When wall or floor demolition is needed, or lines run a long distance, expect higher costs.
Second sinks require both supply and drain lines, as well as venting, which adds to the project scope. If your remodel includes other plumbing improvements or addresses existing issues, we can bundle work to save time and disruption. Checking for proper venting, confirming pipe compatibility, and making sure all connections meet code are steps we never skip.
