Bathroom Remodeling Plumbing Services in Pontiac, IL
You never see bathroom plumbing when it’s done right — but you sure notice it when it’s wrong. Issues like slow drains, hidden leaks behind tile, or inconsistent shower temperatures show up weeks or months after a remodel if the plumbing wasn’t properly installed. We focus on getting the rough-in plumbing perfectly laid out before walls close, guaranteeing your bathroom will function flawlessly for years. If you uncover damp spots or suspect leaks during demo, call us right away — leak detection and repair during remodeling is critical to avoid costly damage later.
When you reach out at 779-217-8849 for bathroom plumbing, we adapt to your project. Simple fixture upgrades like swapping a faucet, toilet, and showerhead in the same spots are quick jobs, often done in a day. If you’re redesigning the layout — relocating the toilet, swapping a tub for a walk-in shower, or adding a double vanity — that requires rough-in plumbing adjustments with new drain and vent lines that need permits and inspections. We manage those steps from start to finish.
I always advise homeowners planning a bathroom remodel to lock in fixture choices before we set rough-in measurements. Toilets, shower valves, and tub fillers vary in rough-in requirements. Finalizing fixtures early helps avoid costly rework if measurements don’t line up with the products you chose.
Our Bathroom Plumbing Services
Shower and Tub Plumbing
Installing shower valves is one of the key plumbing tasks in any bathroom remodel. We position valves at the correct height and depth to match finished walls and connect them to properly sized supply lines for optimal water flow. We install pressure-balance valves, which Illinois code requires in showers and tub-shower combos to prevent scalding, as well as thermostatic valves for precise temperature control and multi-outlet systems for rain showerheads, body sprays, and handheld units.
Tub-to-shower conversions require cutting through the floor for new drains, rerouting or installing shower pan drains with correct slope, building up the shower base for waterproofing, and moving supply lines from the tub filler to the new shower valve location. We’ll clearly explain the scope and timeline before starting. We also install freestanding tubs with supply rough-in for floor- or wall-mounted fillers.
Toilet Installation & Relocation
Replacing a toilet in the same spot is straightforward — see our fixture installation service. Moving a toilet to a new location involves rerouting the drain pipe, which may require cutting concrete or subflooring, installing a flange at the right height for your finished floor, and adjusting the soil stack vent connection. This plumbing work is inspected and permitted to ensure code compliance.
We install standard height, comfort height (ADA compliant), wall-mounted, and dual-flush toilets. If you’re adding a new bathroom or upgrading your existing one, we’ll also check if your water heater can handle increased demand. Planning accessibility features like grab-bar blocking or curbless shower entries is best done early, so we can coordinate with your contractor for proper wall reinforcement.
Vanity & Sink Plumbing
Whether you’re upgrading from a single sink to a double, switching from a pedestal sink to a vanity, or relocating your vanity entirely, we handle the water supply and drain line adjustments. Adding a second sink involves extending hot and cold lines and configuring drains with either shared or separate P-traps, depending on your layout. Changing vanity size often means modifying stub-out heights and drain locations to fit the cabinet.
We handle faucet installation, supply line connections, drain assembly, and P-trap setup as part of vanity work. While the cabinet is open, we recommend swapping out old gate-style shutoff valves for modern quarter-turn ball valves—this upgrade can prevent costly leaks under your sink. If your remodel changes drain locations, we handle all related drain and P-trap adjustments during the rough-in phase.
Complete Rough-In Plumbing for New Bathrooms and Additions
When adding a new bathroom—whether finishing a basement, adding a half bath, or building an en suite—we install all the rough-in plumbing. This includes running hot and cold supply lines from the nearest connection, tying drain lines into the existing stack or building drain, venting through the roof or connecting to existing vents, and setting floor flanges to finished floor height. These steps require permits and inspections before walls close. We work with your general contractor and manage inspection scheduling to keep your project on track.

Tips for a Smoother Bathroom Renovation
- Pick fixtures first: Rough-in plumbing depends on the specific details of fixtures like toilets and shower valves, so decide beforehand.
- Keep plumbing layouts consistent when possible: Moving drains and supply lines adds significant labor and cost.
- Upgrade shutoffs while walls are open: Replacing old gate valves with ball valves now is much cheaper than fixing leaks later.
- Check your water heater size: Larger tubs or adding a second shower might mean you need a more powerful water heater.
- Schedule permits early: Plumbing inspections affect your contractor’s timeline—plan with us from the start.
Bathroom Remodeling Questions Answered
If you’re just swapping fixtures in the same location, usually no permit is needed. But if you’re changing drain lines, moving supply pipes, or reconfiguring the layout, permits are required in the Pontiac area. We handle all the paperwork and inspections so you don’t have to worry. Skipping permits on plumbing rough-in can cause headaches with insurance or resale later.
Yes. Moving a toilet or shower means rerouting drain pipes – often cutting through the concrete slab or subfloor – relocating vent pipe connections, and extending supply lines. It costs more than replacing in the same spot but allows you to customize your layout completely. We’ll provide a detailed quote so you know what to expect.
Best to call us as early as possible — ideally before you open up your walls. Early involvement helps ensure rough-in plumbing is planned correctly for your new fixtures and layout, and we can advise on permit timelines. Waiting until demolition starts can lead to rushed decisions and scheduling issues.
Absolutely. We collaborate closely with general contractors, designers, and homeowners. We handle all the plumbing rough-in work and coordinate inspections to fit your project timeline. Give us a call at 779-217-8849 to discuss how we can support your remodel.
