Bathroom Plumbing Renovations in Glen Ellyn, IL
The plumbing behind your bathroom remodel might be out of sight, but if it’s not done right, you’ll notice the problems down the line — slow drains, leaks hidden behind walls, or shower valves that fail to hold temperature. Doing the plumbing correctly before the drywall goes up is key to avoiding costly headaches later. If you spot any dampness or water stains when opening the walls during your remodel, give us a call — leak detection during this stage is crucial to uncover hidden damage and fix it before sealing it off.
When you call us at 331-267-7498 for your bathroom project, here’s our approach: if you’re simply swapping out fixtures like a new faucet, toilet, or showerhead in the same spots, that’s a quick install we can often complete in a single day. If you’re altering the layout — moving the toilet, converting a tub to a walk-in shower, or adding sinks — that requires more extensive rough-in work with drain and supply line adjustments, permits, and inspections. We handle both types efficiently.
My advice to anyone remodeling a bathroom is to pick your fixtures before we set the rough-in measurements. Toilets, shower valves, and tub fillers all have different rough-in specs. Finalizing your fixtures ahead of time avoids costly rework if rough-ins don’t line up with your selections.
Our Bathroom Plumbing Services
Shower & Tub Plumbing
Installing shower valves properly is one of the most important parts of remodeling. The valve must be installed at the right height and depth behind the finished wall, and supplied with correctly sized pipes to ensure strong water flow. We install pressure-balance valves (required by Illinois code to prevent scalding), thermostatic valves for steady temps, and multi-port valve setups for rain showers, body sprays, and handhelds.
Turning a tub into a shower involves cutting a new drain hole in the floor, repositioning drains at correct slopes, building up the shower base for waterproofing, and rerouting supply lines from the tub filler to the shower valve. This is a bigger job — we’ll review the entire plan and timeline with you before starting. We also install freestanding tubs and run supply lines for both floor and wall-mounted fillers.
Toilet Installation & Relocation
Replacing a toilet in the same spot? Check out our fixture installation service for a quick swap. Moving the toilet to a new wall or position takes more work — we cut through concrete or subfloor, install a new flange at the right height, reroute the drain and soil stack connections, and make sure venting meets code. This is inspected and permitted work before walls and floors close up.
We fit standard, comfort-height (ADA-compliant), wall-mounted, and dual-flush toilets. If you’re adding a bathroom or upgrading, it’s a good time to double-check if your water heater can keep up with your hot water needs. Planning accessibility features like grab bars or curbless showers? Let’s coordinate early on so your GC can add wall blocking before drywall installation.
Vanity & Sink Plumbing
Whether you’re upgrading from a single to double sink, switching from pedestal to vanity, or relocating your vanity entirely, we adjust supply and drain lines accordingly. Adding a second sink means extending hot and cold water lines and configuring drain traps properly. Changing vanity sizes might require moving stub-out heights and drain locations to fit the new cabinetry.
We handle faucet installs, drain assemblies, supply connections, and P-traps as part of vanity setup. While the cabinet is open, we recommend swapping old gate valves for newer quarter-turn ball valves to prevent leaks. If your new layout shifts drain positions, we take care of drain piping and P-trap adjustments during rough-in.
Complete Rough-In for New Bathrooms & Additions
Adding a new bathroom in your Glen Ellyn home — whether finishing a basement, adding a half bath, or an en-suite — means full rough-in plumbing. We run supply lines from the nearest main, connect drain pipes to your existing stack or building drain, install vent pipes through the roof or connect to current vents, and set floor flanges exactly at finished floor height. This work requires permits and inspections before walls go up. We coordinate with your GC and schedule inspections efficiently to keep your project on track.

- Plan permits early: Rough-in inspections affect scheduling—get your plumber involved early.
Bathroom Remodeling Frequently Asked Questions
For simple fixture swaps in the same location, permits generally aren’t needed. But if you’re relocating or adding drain or supply lines, or changing vent piping, permits are usually required in Glen Ellyn. We take care of securing permits and arranging inspections so you don’t have to worry. Skipping permits can cause headaches down the road with insurance or if you sell your home.

The sooner the better—ideally, before the walls are opened. Getting us involved early helps us guide you on rough-in dimensions, what plumbing changes are feasible, and the permit timeline. Last-minute calls after demolition often cause scheduling conflicts and rushed decisions that cost more.
