Bathroom Plumbing Services in Warrenville, IL
Bathroom plumbing is the backbone of any remodel, though it’s hidden from sight when the job’s done. Faulty plumbing can lead to slow drains, leaks behind tile, or inconsistent shower temperatures down the line. Getting the piping, rough-ins, and valves installed correctly before walls go up is crucial for long-lasting performance. If you happen to spot any signs of water damage inside walls during a remodel, give us a call. We offer leak detection services that catch hidden issues before they cause costly damage.
When you reach out to us at 331-244-1542 for your bathroom project, we tailor our approach to your needs. Simple replacements of faucets, toilets, and showerheads in existing locations are quick jobs we usually finish in one day. For more involved projects like relocating the toilet, switching a tub for a walk-in shower, or adding extra sinks, we handle all the rough-in plumbing including drainage, venting, and supply lines—all with proper permitting and inspection.
A tip I always share with homeowners: finalize your fixture choices before the rough-in phase. Toilets, shower valves, and tub fillers all have specific rough-in measurements. Deciding early avoids surprises where the rough-in pipes don’t match your new fixtures, saving you mess and expense later on.
Our Bathroom Plumbing Work Includes
Shower & Tub Plumbing
Installing a shower valve properly is key to solid bathroom plumbing. We set valves at code-compliant heights and depths, and connect them with correctly sized pipes to ensure good water pressure. We install pressure-balance valves, which Illinois code requires to prevent scalding, as well as thermostatic valves for precise temperature control and multi-outlet setups for rain showerheads, body sprays, and hand showers.
For tub-to-shower conversions, the job involves coring the floor for a new drain, adjusting or installing the shower drain with the right slope, building up the floor for waterproofing, and rerouting supply lines from the tub filler spot to the shower valve. It’s a detailed rough-in process that we outline clearly before we start. We also handle freestanding tub installs, managing floor- or wall-mounted filler supply rough-ins.
Toilet Installation & Moving
Replacing a toilet in the same spot is usually a straightforward fixture swap—check out our fixture installation service for details. If you want to move the toilet to a new wall or location, we reroute the drain line—this could mean cutting concrete or subfloor—install a new flange at the correct height for your finished floor, extend the soil stack connection, and ensure proper venting. This requires a permit and inspection before closing walls and floors.
We install a variety of toilets including standard, comfort-height (ADA compliant), wall-mounted, and dual-flush models. If adding a new bathroom or upgrading, it’s a good time to review your water heater capacity to handle extra demand. For bathrooms designed for accessibility, we also coordinate adding grab bar blocking and curbless shower entries in partnership with your GC.
Vanity & Sink Plumbing
Whether adding a second sink, switching from pedestal to vanity, or relocating your vanity, we manage the supply and drain piping changes. Adding extra sinks means extending hot and cold lines and adjusting the drains to share a P-trap or use separate traps based on the setup. Changing vanity size or position often requires adjusting stub-out heights and drain locations to fit the new cabinet.
We install faucets, drains, supply lines, and P-traps as part of vanity setups. While the cabinet is open, we recommend replacing old gate-valve shutoffs with durable quarter-turn ball valves to prevent leaks. If your remodel changes drain positions, we include drain and P-trap connections as part of the rough-in work.
Full Rough-In for New Bathrooms & Additions
Building a new bathroom in your Warrenville home—whether adding a basement bath, half bath, or master suite—requires full plumbing rough-in. We run supply lines from the closest main, install drain lines connected to existing stacks or the building drain, set up vent pipes through the roof or tie into existing vents, and position floor flanges at finished floor height. This work needs permits and inspections before walls are closed. We’ll coordinate timing with your GC and handle all inspection scheduling.

Tips for a Smooth Bathroom Plumbing Project
- Pick fixtures before rough-in: Fixture rough-in dimensions vary—lock in your models early so rough-in pipes match perfectly.
- Stick to existing layouts when possible: Moving plumbing adds significant labor and costs compared to fixture replacements in place.
- Upgrade shutoff valves while walls are open: Swap out old gate valves for reliable quarter-turn ball valves—it saves headaches down the road.
- Check your water heater’s capacity: Larger showers or soaking tubs might require a bigger water heater.
- Schedule permits early: Rough-in inspections impact your contractor’s timeline. Get your plumber involved early to avoid delays.
Frequently Asked Questions
For simple fixture swaps in the same spot, you usually won’t need a permit. But if your project involves moving pipes, adding new supply or drain lines, or changing the bathroom layout, a permit is required in most Warrenville jurisdictions. We take care of securing permits and scheduling inspections so your project stays compliant. Skipping permits on plumbing rough-ins can cause headaches with insurance and resale later on.
Yes, we can relocate toilets or showers, but it means rerouting drains, vents, and supply lines — sometimes cutting into the floor slab or subfloor. It costs more than swapping fixtures in place, but it allows you to redesign your bathroom layout to fit your needs. We’ll provide a detailed quote after evaluating your proposed changes so you can decide if it fits your budget.
It’s best to involve us as soon as possible—ideally before demo begins. Early involvement lets us help with fixture rough-in dimensions, check what’s possible with your existing plumbing stacks and vents, and plan for permits and inspections. Waiting until after demolition can create scheduling conflicts and rushed plumbing decisions that affect your project.
Absolutely, we collaborate directly with GCs, designers, and homeowners. We handle the plumbing scope as a subcontractor and work with your GC to schedule rough-in inspections on time. Give us a call at 331-244-1542 to coordinate your project timeline.
