Cost GuideUpdated June 17, 2026
Kitchens in Niles see decades of daily use, and many homeowners want upgrades that make life easier. Pot fillers above the stove or a second sink for prep and cleanup are practical additions, but older plumbing setups can complicate these projects. If your home is like most in the north suburbs, built in the 1950s to 1970s, you're likely dealing with tough clay soil outside, and sometimes outdated supply lines or hidden pipes inside. That changes how we approach each job, and how much it can cost.
How a Pot Filler or Second Sink Impacts Your Plumbing
Adding either of these features means more than mounting a fixture or cutting a hole in the counter. A pot filler needs a dedicated cold water line run up the wall behind your stove, usually with shutoff valves both in the basement and behind the faucet. A second sink calls for both hot and cold supply lines, plus a new drain line that must tie into your existing kitchen drain, sometimes a challenge in older houses with thick walls or limited space in cabinets.
Many Niles homes still have galvanized steel pipes, especially if the plumbing hasn't been updated since the house was built. These old pipes corrode from the inside out and often can't be tapped for new lines without risking leaks or a full replacement. Homes with copper supply lines or PEX upgrades are usually easier, and cheaper, to modify. The layout and access to plumbing behind kitchen walls can add labor, especially if you have original plaster or tile, which takes extra work to remove and patch. If the water line run is long or crosses over finished rooms, expect costs to go up.
Main Cost Factors for Niles Kitchens
The price to add a pot filler or prep sink in your kitchen will depend on a mix of plumbing, finish work, and fixture quality. These are the main drivers:
- Supply line material and location (galvanized, copper, PEX, access from basement or crawlspace)
- Length of water line run (the farther from existing supply, the more wall, floor, and ceiling work)
- Drain tie-in for second sinks (difficulty depends on cabinet layout, walls, and pipe age)
- Type and quality of the faucet or pot filler (basic chrome vs. high-end finishes)
- Wall patching and finish work (tile, drywall, paint restoration)
- Permits and inspections (required in Cook County for most projects)
Some kitchen layouts make it straightforward to get at plumbing from the basement or unfinished space. Others involve fishing new supply lines through tight joists or around ductwork, this takes more time and labor. Waste lines for a second sink can also be a sticking point, especially if your home has old cast iron or undersized drains. In those cases, we might recommend upgrading nearby pipe sections during the project, especially if there's a history of slow drains. Our pipe repair and repiping team sees this in a lot of mid-century houses in the area.
Warning Signs Your Kitchen Plumbing Needs Extra Attention
Before planning an upgrade, it's smart to take stock of your current system. Some warning signs mean more work (and cost) could be involved:
- Old galvanized pipes (dull gray color, threaded joints)
- Low water pressure at the sink or throughout the house
- Musty odors or signs of water damage in base cabinets
- Frequent slow draining or backups in the kitchen
- Visible corrosion, rust, or flaking on shutoff valves
- Staining around seams or old couplings
If any of these come up, consider having us assess for leaks, supply issues, or the condition of your drain lines. You can learn more about early leak detection and repair on our site. Addressing these problems up front can prevent flooded floors or water damage after the new features are installed.
Typical Steps in the Installation Process
We start by evaluating your current kitchen plumbing, especially the supply and drain lines under the sink, in the basement, or in adjacent walls. For a pot filler, we map a cold line route to the stove area, usually through the basement ceiling or up an interior wall (exterior walls risk freezing in winter, especially during Chicago's cold snaps). For a second sink, both hot and cold lines plus a new vented drain are needed. Tie-ins must pitch properly and connect with the right fittings. Permits are secured before work begins, and we handle restoration of any opened walls or finished surfaces when the plumbing is done.
In many cases, homeowners also consider upgrading their kitchen faucet or adding a garbage disposal at the same time. It's common for us to coordinate fixture installation or include garbage disposal work during these remodels. Keeping related projects together often saves time and avoids duplicate labor costs.
How Hard Water and Old Pipes Affect Kitchen Projects
Niles gets municipal water sourced from Lake Michigan, which is moderately hard. This means mineral buildup can shorten the life of new fixtures if you're connecting to old galvanized or scale-prone copper pipes. We sometimes recommend a flush or cleaning before tying in new faucets, or even a partial repipe in the worst cases. If you're upgrading kitchen fixtures in a house that's 50-70 years old, consider an evaluation of your water heater as well. Our water heater services can help prevent future supply or pressure issues at your new pot filler or prep sink.
Basement and crawlspace access is another local concern, thanks to Niles' flat terrain and moderate water table. Plumbing runs here are usually straightforward, but we do check for any signs of basement seepage or previous sump pump work which might affect the safe location of new water lines. Learn about sump pump services if you're experiencing wet basement conditions during kitchen remodeling.
Budgeting Tips for Your Remodel
The biggest thing you control is the scope of finish work and the type of fixtures you pick. Tiling or wall patching costs add up quickly if we have to open finished surfaces. Choosing accessible routes for new lines and planning upgrades with nearby projects can keep your budget in check. Be aware that permit requirements in Cook County are strict, and all new supply lines must be properly supported and inspected. If your home has had multiple remodels over the years, we may find a mix of pipe materials or patchwork repairs behind the walls, every discovery can change the plan and the cost.
