Bathroom Plumbing Services in Northbrook, IL
The hidden complexity of bathroom plumbing often goes unnoticed—until slow drains, hidden leaks behind tiles, or inconsistent shower temps show up weeks later. Proper plumbing setup before walls are sealed ensures your bathroom performs flawlessly for years. If during your remodel you stumble upon damp spots or water damage behind walls, give us a call. Our expertise in leak detection can spot and fix problems before they become costly headaches.
When you reach out to us at 224-524-1068 about your bathroom upgrade, here’s our approach: simple swaps like replacing faucets, toilets, or showerheads in the same spots are quick installs, usually done within a day. But if your plans include moving fixtures, converting tubs to showers, or adding sinks, that involves more complex rough-in work requiring permits and inspections. We handle all aspects, no matter the scale.
A pro tip: finalize your fixture choices before rough-in plumbing begins. Toilets, shower valves, and tub fillers each have specific rough-in dimensions. Locking in your selections early avoids costly adjustments after framing is done, saving you frustration and extra expense.
Our Bathroom Plumbing Services
Shower & Tub Plumbing
Installing a shower valve is a critical part of any bathroom remodel. We position valves at exact heights and depths to fit your tile and finish work and size supply lines for steady water flow. We install pressure-balancing valves, as required by Illinois code to prevent scalding, thermostatic valves for precise temp control, and multi-port valves for rain showers, body sprays, and hand showers.
Converting a tub into a walk-in shower involves cutting a new drain access, setting proper slopes, preparing the floor for waterproof membranes, and rerouting water supply lines. We’ll review all these steps with you before starting. We also do supply rough-ins for freestanding tubs, whether floor-mounted or wall-mounted fillers are part of the setup.
Toilet Installation & Relocation
Replacing a toilet in its existing spot is a quick project—check out our fixture installation service for details. Moving the toilet means rerouting drain pipes—this often requires cutting into the slab or subfloor—and installing a new flange at the proper height. We’ll also extend or reroute the vent stack to meet code and ensure proper airflow. All this is done with the required permits and inspections.
We install all types: standard, comfort height (ADA compliant), wall-mounted, and dual-flush models. If you’re adding a bathroom or upgrading an existing one, it’s a great time to review your water heater capacity to meet increased hot water demand, especially if adding a soak tub or second shower. Planning for grab bar blocking or curbless showers? We coordinate with your GC to prep walls before drywall goes up.
Vanity & Sink Plumbing
Whether you’re converting from one sink to double sinks, switching from a pedestal to a vanity, or moving your vanity to a different wall, we manage all the necessary pipe adjustments. Adding a second sink means extending hot and cold lines and adapting or adding P-traps. Size changes to your vanity cabinet require adjustments to supply and drain stub-outs.
We install faucets, drains, supply lines, and P-traps during vanity setup. While cabinets are open, we recommend replacing outdated gate valves with modern quarter-turn ball valves to prevent leaks and water damage under your sink. If your remodel changes drain locations, we also handle drain lines and trap connections as part of the rough-in.
Full Rough-In Plumbing for New Bathrooms & Additions
Installing a new bathroom in your Northbrook home means running supply lines from the closest main, tying drain lines into existing stacks or the building drain, and installing vent pipes that extend to the roof or join existing vents. Flanges and fixtures are set to finished floor height. This kind of work requires permits and inspections at the rough-in phase. We work closely with your GC to coordinate scheduling and pass all inspections for a smooth build.

- Upgrade shutoff valves now: Swap old gate valves for ball valves while walls and cabinets are accessible to avoid future leaks.

- Plan permits early: Plumbing rough-in inspections can impact your contractor’s timeline, so involve us early in the planning phase.
Common Questions About Bathroom Remodeling Plumbing
If you're only replacing fixtures in the same spots, usually no permit is required. But if you’re adjusting drain lines, vent pipes, or supply rough-in locations, a permit is required by most municipalities around Northbrook. We take care of securing permits and scheduling inspections so your project meets all local requirements. Skipping permits can cause problems with insurance claims and future home sales.
Yes, but it involves rerouting the drain line—which may require cutting into the subfloor or concrete slab—moving the vent connection, and extending supply lines. This adds to the cost compared to replacing fixtures in place, but it lets you redesign the space. We’ll provide a detailed quote so you can decide what fits your budget.
It’s best to get us involved before walls are opened. Early consultation helps you understand fixture rough-in requirements, verify what existing drain and vent stacks can accommodate, and plan permit timing.
