Bathroom Plumbing Remodeling Services in Elmhurst, IL
The plumbing hidden behind your bathroom walls is what keeps everything flowing smoothly for years. If the work isn’t done right, you might not notice until you get slow drains, water damage behind tile, or inconsistent shower temperatures. Doing the plumbing correctly before closing the walls makes all the difference for trouble-free use. If you uncover damp spots or mold while opening up walls, call us immediately — our leak detection expertise can find and address hidden leaks before they cause bigger headaches.
When you call us at 331-704-1094, here’s how we handle your bathroom update: simple fixture replacements like swapping out a faucet, toilet, or showerhead in the same spots are generally quick installs we can finish in a day. But moving fixtures around — relocating the toilet, turning a tub into a walk-in shower, adding a sink — involves reworking drain, vent, and supply lines and requires permits and inspections. We take care of both small and complex jobs.
I always advise homeowners to pick out their fixtures before we set rough-in measurements. Each model has specific dimensions, so finalizing your selections first avoids having to redo plumbing rough-ins later, saving time and money.
Our Bathroom Plumbing Services
Shower & Tub Plumbing
Installing shower valves is critical — the valve must be positioned at the correct height and depth to meet both code and comfort standards. We use pressure-balance valves, which Illinois code requires to prevent scalding, thermostatic valves for steady temperature control, and multi-outlet systems for rain showers, body sprays, and hand showers.
Converting a tub to a shower means drilling a new drain hole, setting the drain with proper slope, raising the floor for waterproofing, and moving supply lines. It’s a bigger job, and we’ll review the full details and timing before we begin. We also handle supply line rough-in for freestanding tubs with floor- or wall-mounted fillers.
Toilet Installation & Relocation
Replacing a toilet in the same spot is straightforward — see our fixture installation page for details. Moving a toilet requires moving the drain line by cutting into the floor or slab, installing the correct flange height for your finished floor, adjusting the soil stack vent connection, and ensuring proper venting. It’s all permitted and inspected work.
We install all styles including standard height, comfort height (ADA compliant), wall-mounted, and dual-flush models. If you’re adding a bathroom or updating an existing one, it’s a good idea to check if your water heater has enough capacity for any new fixtures. Accessibility upgrades like grab bar blocking or curbless showers are best planned early so we can coordinate with your contractor on framing before drywall goes up.
Vanity & Sink Plumbing
Whether you’re adding a second sink, switching from pedestal to vanity, or relocating a vanity, we adjust hot and cold supply lines and drain connections as needed. Sometimes that means splitting the drains with separate P-traps or combining into one based on your setup. Changing vanity size may mean adjusting stub-out heights and drain positions to fit perfectly.
We handle faucet, drain, supply line connections, and P-trap installations as part of vanity setup. While we’re under the sink, we often swap out old gate valves for quarter-turn ball valves—they’re way more reliable and prevent leaks. If drain locations change, we also take care of rerouting drains and P-traps as part of the project.
Complete Rough-In For New Bathrooms & Additions
Building a new bathroom in your Elmhurst home—whether a basement bath, half bath, or master suite—requires full plumbing rough-in. This means running supply lines from your home’s main water source, installing drain lines connected to the stack or building drain, running vent pipes through the roof or tying into existing vents, and setting floor flanges at the finished floor height. This work needs permits and inspections before walls close. We work closely with your contractor to schedule inspections and keep your project on track.

Bathroom Remodel Tips
- Choose fixtures early: Different models require specific rough-in measurements—decide before plumbing starts.
- Stick to existing layouts if possible: Moving plumbing adds labor and cost.
- Upgrade shutoff valves during remodel: It’s easier and prevents future leaks.
- Check your water heater size: Large tubs or added showers may need more hot water capacity; we can help assess.
- Start permit process early: Plumbing inspections can affect your contractor's schedule—plan ahead.
Bathroom Remodeling Plumbing FAQ
If you’re just swapping fixtures in the same spots, a permit usually isn't needed. But anytime you move drains, vents, or supply pipes, permits are required in most Elmhurst jurisdictions. We take care of the permit paperwork and schedule inspections so everything is done by the book. Skipping permits can cause trouble with insurance and selling your home later.
Yes, we can relocate toilets, showers, or tubs, but it involves rerouting drainage lines (which might mean cutting into the floor or slab), adjusting venting, and extending supply plumbing. This adds cost compared to replacing fixtures in the same location but gives you full freedom to reconfigure your bathroom. We’ll provide detailed pricing so you can decide what works best.
It’s best to get us involved early—before walls are removed or framing is finished. Early input helps us ensure your fixture rough-in dimensions match your choices and that your existing drain and vent setup can support your design. Last-minute calls after demolition often create rushed layouts and scheduling headaches.
Absolutely. We collaborate with GCs, designers, and homeowners alike. We manage the plumbing scope as a subcontractor and coordinate rough-in inspections to fit your project timeline. Give us a call at 331-704-1094 to discuss your plans.
