Expert Bathroom Plumbing Services in Grayslake, IL
The plumbing work behind your bathroom remodel is invisible once finished, but its quality determines if problems like slow drains, hidden leaks, or unreliable shower temperatures pop up months or years later. Precise plumbing rough-in before walls go up is crucial for a trouble-free bathroom that functions well for decades. If you’re peeling back old walls and notice signs of moisture damage, give us a call — leak detection at this stage lets us catch hidden leaks before they become costly headaches.
When you reach out at 224-814-5106 to discuss your bathroom remodel, we tailor our approach based on your needs. For simple upgrades where fixtures stay put (like installing a new faucet, toilet, or showerhead), we often complete the job in a single visit. Changing room layouts—such as moving a toilet, turning a tub into a walk-in shower, or adding a double vanity—requires comprehensive rough-in work with supply, drain, and vent adjustments. This work needs permits and inspections, and we manage that process end-to-end.
I always advise homeowners to finalize fixture choices before rough-in begins. Toilets, shower valves, and tub fillers each have specific dimensions for proper rough-in placement. If you wait to decide, you risk costly rework to adjust pipe locations to fit your fixtures.
Our Bathroom Plumbing Services
Shower & Tub Plumbing
Installing shower valves correctly is vital. We set valves at the right height and depth from the finished wall, using properly sized supply lines to ensure steady water flow. We fit pressure-balancing valves required by Illinois code to prevent scalding, thermostatic valves for consistent temperature control, and multi-outlet valves for setups with rainheads, body sprays, and hand showers.
For tub-to-shower conversions, we core the floor for new drains, rework shower pan drains at proper slopes, prep floors for waterproof membranes, and reroute supply lines from tub fillers to shower valves. These are complex rough-in tasks we’ll explain fully before we get started. We also install freestanding tubs, including necessary rough-in for floor- or wall-mounted fillers.
Toilet Installation & Relocation
Replacing a toilet in the same spot is a straightforward job covered by our fixture installation service. But moving a toilet means cutting into concrete or subfloor, rerouting drain lines, placing new flanges at finished floor height, and adjusting soil stacks and vents. This work is inspected and permitted to meet local codes.
We install standard, comfort-height (ADA compliant), wall-hung, and dual-flush toilets. When you’re adding or upgrading bathrooms, we recommend checking if your water heater can keep up with any increased hot water demand. Planning accessibility features like grab bar blocking or curbless showers is easier when we coordinate early with your general contractor.
Vanity & Sink Plumbing
Whether you’re converting a single sink to a double, switching from a pedestal sink to a vanity, or relocating a vanity altogether, we adjust supply and drain lines accordingly. Adding a second sink means extending hot and cold water lines and managing drain connections with either shared or separate traps, depending on your setup. Changes may require repositioning stub-outs to fit new cabinetry.
Our team installs faucets, drain assemblies, supply lines, and P-traps during vanity setup. While cabinets are open, we replace old gate valves with modern quarter-turn ball valves to reduce the risk of leak-related damage. If your layout changes drain locations, we also handle drain and P-trap hookups as part of the rough-in.
Full Rough-In Plumbing for New Bathrooms & Additions
Adding a new bathroom in your Grayslake home—whether finishing a basement, building a half bath, or creating an en-suite—calls for complete rough-in plumbing. We run supply lines from the nearest accessible source, tie drain lines into existing stacks or the building sewer, install vent pipes through the roof or connect to existing vents, and set floor flanges precisely at finished floor height. These steps require permits and inspections, and we coordinate closely with your general contractor to keep the project on track.

Helpful Tips for Your Bathroom Remodel
- Pick fixtures before rough-in: Each toilet, tub, or shower valve has unique rough-in measurements—finalize selections early to avoid costly errors.
- Stick to existing layouts when possible: Moving plumbing drains and vents increases labor and material costs significantly.
- Upgrade shutoff valves while walls are open: Replacing old gate valves now saves you from leaks and damage later on.
- Verify your water heater’s capacity: Larger tubs or additional showers may require a bigger or more efficient unit—see our water heater services.
- Start permits early: Scheduling inspections impacts your contractor’s timeline, so involve plumbing early to keep everything running smoothly.

If you’re just swapping out fixtures where they already sit, usually no permit is needed. But for any rerouting of drains, vents, or supply lines, or changing the layout, permits are required in Grayslake.
