Bathroom Plumbing Remodeling in Oak Brook, IL
Plumbing hidden behind walls makes or breaks a bathroom remodel. Mistakes here can lead to slow drains, leaks behind tiles, or unpredictable shower temperatures down the line. Getting the plumbing right before closing up the walls ensures your bathroom works properly for years to come. If you find signs of water damage while tearing into walls, give us a call — leak detection during remodels is the best time to catch and fix trouble before it causes bigger headaches.
When you call us at 331-202-1402 about your bathroom remodel, here’s the deal: simple fixture swaps (like replacing faucets, toilets, or showerheads in the same spots) are usually quick, often done in a day. If you’re shifting the toilet, switching from a tub to a shower, or adding sinks, that requires rerouting supply, drain, and vent pipes and pulling permits for inspections. We handle both smaller installs and full rough-in plumbing with professionalism.
I always advise homeowners to pick their fixtures before rough-in begins. Different toilets, shower valves, and tub spouts mean different pipe placement and dimensions. Settling on your fixtures first avoids costly rework if rough-in measurements don’t match what you ordered.
Our Bathroom Plumbing Services
Shower & Tub Plumbing
Installing shower valves requires precision. They must be set at the correct height and depth from the finished wall, with supply lines sized right to maintain water flow. We install pressure-balance valves per Illinois code to prevent scalding, thermostatic valves for exact temp control, and multi-outlet valves for rain showers, body sprays, and hand sprays.
Converting a tub to a shower means coring floors for drains, relocating shower pans at proper slopes, building up floors for waterproof liners, and redirecting supply lines. It’s a detailed job — we’ll clearly explain your project’s full scope and timeline before starting. We also supply and install plumbing rough-ins for freestanding tubs, floor-mount or wall-mount filler valves included.
Toilet Installation & Moving
Replacing a toilet in its current location is straightforward — check out our fixture installation for details. Moving a toilet means re-routing the drain line, which can involve cutting concrete or subfloor, installing a new flange at the right finished floor height, extending soil stack connections, and ensuring proper venting. This is permit-required and needs inspection before sealing walls and floors.
We install all types: standard, comfort-height (ADA), wall-hung, and dual-flush toilets. Adding or renovating a bath is a good time to check if your water heater can handle extra demand. Accessibility upgrades like grab bar blocking or curbless showers should be planned with us early so we can work with your GC on wall blocking before drywall goes up.
Vanity & Sink Plumbing
Whether converting a single sink vanity to double sinks, switching from pedestal to vanity, or relocating the vanity completely, we handle all supply and drain changes. Adding a sink means extending hot and cold lines and adjusting drains, either joining a shared P-trap or installing individual traps, depending on your setup. Changing vanity dimensions usually requires moving stub-outs to fit.
We install faucets, drain assemblies, supply lines, and P-traps as part of vanity setup. While cabinets are open, we recommend replacing old gate valves with modern ball valves to reduce future leaks — these shutdowns often fail and cause under-sink water damage. If your remodel shifts drains, we take care of all drain and P-trap connections during rough-in.
Full Rough-In Plumbing for New Bathrooms & Additions
Adding a bathroom in your Oak Brook home, whether it’s a basement bath, half bath, or en-suite, calls for full plumbing rough-in. This includes running supply lines from the closest main shutoff, connecting drain lines to the existing stack or main drain, vent pipes routed through the roof or joined to existing vents, and setting floor flanges at finished floor height. This work requires permits and inspections during the rough-in stage before walls close. We coordinate closely with your GC and schedule inspections on time to keep your project on track.

Bathroom Remodeling FAQs
If you’re just swapping out fixtures like toilets or faucets in the same spot, usually no permit is needed. But any work that moves drains, supply lines, or vents almost always requires a permit in the Oak Brook area. We handle all permitting and inspections to keep your project up to code. Skipping permits can cause trouble later with insurance and resale.
Yes, but it involves cutting into the subfloor or concrete to reroute drains and vents, plus extending supply lines. This adds cost but gives you flexibility to redesign your space. We provide a detailed estimate for layout changes so you can decide if it fits your budget.
Ideally, get us involved before demo starts. Early input helps ensure fixture rough-in dimensions fit your chosen products, existing vent and drain layouts can accommodate changes, and permits are arranged on time. Calling last minute can cause scheduling headaches and rushed decisions.
