Precise Plumbing for Bathroom Remodels in Oak Park, IL
The secret to a bathroom that functions perfectly for years lies beneath the surface — the plumbing. If the pipes, valves, or vents aren’t installed correctly during your remodel, issues like slow draining, leaks behind walls, or fluctuating shower temps can surface weeks or months later. Proper plumbing rough-in before closing walls ensures your new bathroom runs smoothly for decades. If demolition uncovers moisture damage or leaks, contact us — we specialize in leak detection that can catch hidden problems before repairs are covered up again.
When you reach out at 708-742-7564 to discuss your bathroom update, here’s how we approach it: For simple fixture upgrades (like installing a new toilet, faucet, or showerhead in the current locations), it’s usually a quick job done in a day. But if you want to change the layout — move the toilet, switch a tub to a walk-in shower, or add a double vanity — that means new rough-in plumbing with drains, vents, and supply lines requiring permits and inspections. We handle both small and complex jobs with care.
Here’s a tip I always share: finalize your fixture choices before we install the rough-in pipes. Different brands and models of toilets, shower valves, and tub spouts have varying rough-in specs. Locking in your fixtures early stops costly rework of plumbing rough-in that happens when dimensions don’t match the hardware.
Our Bathroom Plumbing Services
Shower & Tub Plumbing Setup
Installing shower valves correctly is crucial — they have to be placed at precise heights and depths aligned with finished walls, plus connected with pipes sized to provide proper water pressure. We install pressure-balance valves (required by Illinois code to prevent scalding), thermostatic valves for stable temperature control, and advanced valve systems for multi-function showers including rain heads and body sprays.
When converting a tub to a shower, we core through concrete floors for new drains, set shower pan drains with the proper pitch, build up the subfloor for waterproof liners, and reroute supply pipes from tub fillers to shower valves. It’s a big job, so we’ll discuss the full process and timeline upfront. We also do plumbing rough-ins for freestanding tubs and supply lines for floor or wall-mounted fillers.
Toilet Installation & Relocation
Replacing a toilet in the same spot is a straightforward task — see our fixture installation services for this. Moving a toilet to a new wall or position calls for rerouting the drain line, cutting into the subfloor or concrete slab as needed, installing the flange at the right height for your finished floor, extending or connecting to the soil stack, and ensuring proper venting. This work is inspected and permitted.
We install all types—standard, comfort height (ADA compliant), wall-mounted, and dual-flush toilets. Adding a new bathroom or upgrading an existing one? That’s also a good time to check if your water heater can handle more hot water demand. If your remodel includes accessibility features like grab bars or curbless showers, we coordinate with your GC to prep wall blocking before drywall goes up.
Vanity & Sink Plumbing
Whether you’re switching from a pedestal sink to a vanity, adding a second sink, or relocating the vanity entirely, we adjust supply lines and drains accordingly. Adding a second sink means extending hot and cold water pipes and configuring the drain with either a shared or separate P-traps, depending on the setup. Adjusting vanity size often calls for moving stub-outs and drains to fit the new cabinet.
We handle faucet installation, drain assemblies, supply valves, and P-traps during vanity setup. While cabinets are open, we recommend upgrading old gate valves to modern quarter-turn ball valves to prevent leaks — we see a lot of water damage from failing shutoffs. If your remodel changes drain locations, we take care of the drain and P-trap connections as part of the rough-in work.
Full Rough-In for New Bathrooms & Additions
Adding a new bathroom in your Oak Park home—like a basement bath, half bath, or master suite—means running fresh supply lines from the main water source, installing drain pipes connected to existing stacks or main drains, setting up vent pipes through the roof or to existing vents, and fitting floor flanges at the right height. This scope requires permits and inspections during rough-in before walls close. We coordinate with your contractor and inspections to keep things on track—this is routine for us.

- Pick your fixtures before rough-in: Pipes must align with your chosen toilet, tub, or shower valve—finalizing early avoids surprises
- Keep plumbing layouts consistent when possible: Moving plumbing lines adds labor and costs
- Upgrade shutoff valves while walls are open: Old gate valves often fail and cause leaks later
- Check your water heater’s capacity: Additional or larger fixtures might require a bigger heater; see our water heater services
- Plan for permits ahead of time: Rough-in inspections can affect your contractor’s schedule, so involve your plumber early
Bathroom Remodeling FAQs
If you’re just swapping out fixtures in the same spot, permits generally aren’t required. But if you’re moving or adding drains, vents, or supply lines, a permit is necessary in most Oak Park localities. We manage the permit applications and inspections so that your plumbing work is fully compliant. Skipping permits can cause problems with insurance and future home sales.
