Bathroom Remodeling Plumbing in Forest Park, IL
Plumbing work in a bathroom remodel mostly happens behind the scenes, but if it’s not done right, problems like slow drainage, hidden leaks, or inconsistent shower temperatures can surface weeks or months after. Proper rough-in plumbing before drywall goes up is key to a bathroom that functions trouble-free for decades. If you uncover damp spots or water stains during demolition, give us a call for leak detection — catching hidden leaks during remodeling saves headaches later.
When you reach out at 708-834-6233 for bathroom plumbing, our process is straightforward. For a basic fixture update like installing a new toilet, faucet, or showerhead in the existing spots, we can usually complete the work within a day. But if you’re planning on shifting plumbing locations—such as moving the toilet, switching from tub to shower, or adding a second vanity sink—that involves detailed pipe rerouting, permits, and inspections. We manage all of it so you don’t have to.
One tip I always share with clients: finalize your fixture selections before we set the rough-in plumbing. Toilets, shower valves, and tub spouts all have specific rough-in measurements. Locking these down early helps avoid costly adjustments after pipes are installed.
Our Bathroom Plumbing Services
Shower & Tub Plumbing Installations
Installing shower valves is one of the most important plumbing steps during a remodel. We position valves precisely for height and depth to match tile and wall finishes, and connect supply lines sized to provide consistent water flow. We install pressure-balance valves as required by Illinois code to prevent scalding, thermostatic valves for fine temperature control, and multi-function valve setups for rain heads and body sprays.
Converting a bathtub to a shower includes coring the floor for a new drain, relocating or setting up a shower pan drain with correct slope, building up the shower base for waterproofing, and redirecting supply lines from the tub faucet to the new shower valve. These are complex rough-in tasks—we’ll review the full plan and timeline with you before starting. We also set plumbing for freestanding tubs, including floor- or wall-mounted fillers.
Toilet Installation and Moving
Replacing a toilet in the same spot is a simple fixture swap—see our fixture installation for this service. When relocating a toilet, we reroute drain lines by cutting concrete or subfloor as needed, install a new flange at the right height, and extend soil stack and vent piping to maintain code compliance. This job requires permits and inspections before closing walls.
We install standard, comfort-height (ADA compliant), wall-mounted, and dual-flush toilets. If you’re expanding or adding a bathroom, it’s also a good moment to assess your water heater’s capacity for increased hot water use. Planning accessibility upgrades such as grab bars or walk-in showers is best done early so we can coordinate plumbing and blocking work with your contractor.
Vanity and Sink Plumbing
Whether you’re upgrading from a pedestal sink to a vanity, adding a second sink, or relocating your vanity, we adjust supply and drain lines accordingly. Adding a second sink means extending hot and cold water lines and configuring drains with either a shared P-trap or separate traps based on your vanity’s layout. Changing the vanity size may require moving supply stub-outs and drain locations to fit perfectly.
We handle faucet installs, drain assemblies, supply hookups, and P-traps. We also replace outdated globe or gate shutoff valves with modern quarter-turn ball valves while the cabinetry is open, which helps avoid common under-sink leaks. If your remodel changes drain positions, we handle the necessary drain and trap connections during rough-in.
Full Rough-In Plumbing for New Baths & Additions
Building a new bathroom in your Forest Park home, whether a basement bath, half-bath, or master suite, requires a full plumbing rough-in: water supply runs from the nearest main line, drain lines connect to the existing stack or building drain, vents extend through the roof or join into existing vent pipes, and floor flanges are set to finished floor height. These plumbing steps need permits and inspections before walls are closed. We coordinate with your general contractor and handle scheduling inspections as part of our service.

Bathroom Remodeling FAQ
If you’re just swapping out fixtures in the same spot, generally no permit is needed. However, if you plan to alter drain, vent, or supply piping, a permit is required in most municipalities around Forest Park. We take care of securing the permit and scheduling inspections so your project complies with code. Skipping permits can cause issues with insurance or home resale down the line.
