Plumbing for Bathroom Remodeling in Winnetka, IL
Behind every great bathroom remodel is solid plumbing that you don’t notice—until something goes wrong. Faulty rough-ins can cause long-term problems like slow draining, leaks behind walls, or erratic water temperature control. Making sure the plumbing is set right before closing walls keeps your bathroom functioning smoothly for years. If you tear into walls during renovations and see damp spots or mold, give us a call. Spotting hidden leaks early with our leak detection service can save you headaches down the road.
When you reach out at 847-307-7041 for bathroom plumbing help, we tailor our work to your project. Simple upgrades that replace faucets, toilets, or showerheads in the same spot are straightforward and usually done within a day. But if you’re shifting plumbing—like moving the toilet, swapping a tub for a walk-in shower, or adding an extra sink—that means rough-in piping changes, permits, and inspections. We manage all parts of the job.
I always advise homeowners to pick their fixtures early in the process. Toilets, shower valves, and tub fillers all have specific rough-in requirements. Finalizing fixtures before we set pipe rough-ins avoids costly mistakes like framing for the wrong rough-in measurements, which can lead to delays and rework.
Our Bathroom Plumbing Services
Shower & Tub Plumbing
Installing shower valves properly is a cornerstone of bathroom plumbing. We set valves at code-compliant heights and depths, using correctly sized supply lines to deliver steady water flow. Illinois plumbing code requires pressure-balance valves in showers and tub/shower combos to prevent scalding; we also install thermostatic valves for precise temperature control and multi-outlet valves for rain showers, body sprays, and hand-held units.
Tub-to-shower conversions are more involved — holes cut in the floor for new drains, shower pan installation with proper slope, and rerouting supply lines from the tub filler to the new shower valve. We’ll walk you through the timeline and scope before any work begins. If you’re installing a freestanding tub, we can rough-in supplies for floor-mounted or wall-mounted fillers too.
Toilet Installation & Relocation
Replacing a toilet where it currently sits is a quick job you can find under our fixture installation services. Moving a toilet to a different wall or location is more complex — we cut through concrete or subfloor as needed, install the flange at the proper height, extend or reroute the waste stack, and ensure vents are connected correctly. This work requires permits and inspections before closing floors and walls.
We install all types: standard height, comfort height (ADA compliant), wall hung, and dual-flush models. Upgrading your bathroom or adding accessibility features? It’s a good time to discuss whether your water heater can handle extra demand and if grab bar blocking or curbless entry needs coordination with your contractor before drywall goes up.
Vanity & Sink Plumbing
Whether you’re converting a single sink to double, swapping a pedestal for a vanity, or relocating the vanity entirely, we manage the plumbing changes. Adding a second sink involves extending both hot and cold supply lines and configuring drains with shared or individual P-traps depending on the layout. Adjustments to drain stub-out heights and locations are part of our service when cabinet sizes change.
We handle faucet hookup, drain assembly, supply connections, and install P-traps. While the cabinet is open, we recommend upgrading old gate-style shutoff valves to modern quarter-turn ball valves—much more reliable and a big help in preventing under-sink leaks. If your new layout moves drains, we also provide drain and P-trap connection services during rough-in.
Full Bathroom Rough-In for Additions & New Builds
Building a new bathroom in your Winnetka home—whether it’s a basement bath, half bath, or master suite addition—means full rough-in plumbing. That includes running supply lines from the closest main, tying drain lines into the existing stack or building drain, installing vent pipes through the roof or connecting to vents, and setting floor flanges precisely at finished floor height. This phase requires permits and inspections before walls get closed. We work closely with your GC and schedule everything so the plumbing inspections fit your project timeline.

Tips to Simplify Your Bathroom Remodel
- Choose fixtures before rough-in: Rough-in measurements vary by fixture model—finalize selections early to avoid costly adjustments.
- Keep plumbing layouts where possible: Shifting fixtures means more labor and expense than replacing in place.
- Upgrade shutoffs while walls are open: Switching old valves now can prevent future leaks and damage.
- Check hot water system capacity: Adding tubs or extra showers may require a larger water heater.
- Plan permits early: Plumbing inspections affect your timeline—loop the plumber in before demolition.
Frequently Asked Questions About Bathroom Remodeling Plumbing
If you’re swapping fixtures in the same place, usually no permit is needed.
