Bathroom Plumbing Services Built to Last in Northlake, IL
Behind every solid bathroom remodel is reliable plumbing hidden inside the walls. Mistakes here don’t show immediately but lead to slow drains, hidden leaks, or inconsistent shower temperatures months down the line. The key is getting plumbing rough-in done precisely before drywall goes up so your bathroom operates flawlessly for years. If you open up existing walls and spot signs of moisture or mold, call us for expert leak detection—addressing problems now prevents costly damage later.
When you call us at 708-773-5709 to discuss your bathroom update, we’ll tailor our approach to fit your needs. For simple updates replacing faucets, toilets, or showerheads in the same spots, we can usually finish plumbing work within a day. Changing the bathroom layout, such as moving a toilet, converting a tub to a shower, or adding a double vanity, involves more complex rough-in work with drains, vents, and water lines—all requiring permits and inspections, which we handle for you.
My advice to every homeowner planning a remodel: finalize your fixture choices before rough-in begins. Toilets, shower valves, and tubs all have different rough-in specs. Locking in your selections early helps avoid costly rework if rough-in dimensions don’t match the fixtures you want later.
Our Bathroom Plumbing Services
Shower & Tub Plumbing Installation
Installing shower valves correctly is crucial. They must be placed at the proper height and depth behind the finished wall, with supply lines sized for steady flow. We fit pressure-balance valves (required here in Illinois to avoid scalding), thermostatic valves for constant temperature, and multi-outlet valves for rain showers, body sprays, and handhelds.
Tub-to-shower conversions involve drilling a new drain hole, relocating or installing a shower pan drain with correct slope, building up the floor for waterproofing, and rerouting water supply. This work is detailed and requires careful planning; we’ll review everything and provide a timeline before we begin. We also handle supply rough-ins for freestanding tubs with floor or wall-mounted fillers.
Toilet Installation & Relocation Services
Replacing a toilet in the same spot is straightforward and covered under our fixture installation service. Moving a toilet means rerouting the drain lines, often cutting concrete or subfloor, installing a new flange at the correct finished floor height, extending or adjusting vent stacks, and ensuring code-compliant venting. This work requires permits and inspection before walls and floors are sealed up.
We install all types—standard, comfort height, wall-hung, and dual-flush units. Adding a new bathroom or upgrading fixtures is also a great time to assess if your water heater can handle extra demand—especially with more showers or tubs. Planning accessibility features such as grab bars or curbless showers? Let us coordinate with your GC early for blocking installation before drywall goes up.
Vanity & Sink Plumbing
Whether you’re switching from a pedestal sink to a vanity, adding a second sink, or relocating a vanity, we adjust supply and drain lines accordingly. Adding sinks requires extending hot and cold water lines and configuring drains with shared or individual P-traps based on layout. Changing vanity size may mean adjusting stub-out locations as well.
We handle faucet installation, drain and supply hookups, and P-trap setup as part of the job. While the vanity cabinet is open, we recommend upgrading old gate valves to modern quarter-turn ball valves to reduce future leak risks. For layout changes that move drains, we'll also manage drain and P-trap connections during rough-in.

Building a new bathroom in your Northlake home—whether finishing a basement, adding a half bath, or creating an en-suite—needs complete rough-in plumbing. This includes running supply lines from the nearest main, connecting drains to existing stacks or the building drain, installing vent pipes through the roof or tapping into vents, and setting floor flanges at the finished floor height. Permits and inspections are required for this phase, and we handle scheduling and coordination with your GC as part of our process.
