Reliable Bathroom Plumbing in Downers Grove, IL
Bathroom plumbing is mostly hidden once finished, which means mistakes often go unnoticed until leaks or drainage problems pop up later. Properly installed plumbing during your remodel ensures your bathroom functions well for years, avoiding messy and costly repairs. If you uncover signs of water damage when opening walls, give us a call — performing leak detection during a remodel is smart, so hidden leaks don’t cause problems down the road.
When you reach out at 331-260-0956 for your bathroom project, we’ll discuss your plans. Simple fixture updates—like replacing faucets, toilets, or showerheads without moving them—can often be done in a day. But if you’re reshaping your bathroom’s layout by moving fixtures, converting tubs to showers, or adding sinks, that involves permits, rough-in plumbing, and more extensive work that we handle from start to finish.
I always advise homeowners to pick their fixtures before we set any rough-in measurements. Toilets, shower valves, and tub fillers have specific rough-in specs. Finalizing your selections first helps avoid redoing plumbing if the dimensions don’t match your products, saving frustration and expense.
Our Bathroom Plumbing Services
Shower & Tub Plumbing
Installing shower valves is a key step requiring precise placement and correct depth from the finished wall. We work with pressure-balance valves — which Illinois code mandates to avoid scalding — as well as thermostatic valves for steady temperature control. We also handle multi-outlet systems for rain showerheads, body sprays, and hand showers.
Converting a tub to a shower means coring the slab for a new drain, adjusting slopes for proper drainage, preparing the shower floor for waterproof liners, and rerouting supply lines from the tub faucet to the shower valve. This is one of the more involved plumbing tasks, so we take time to review the full plan and timeline with you. We also do supply rough-ins for freestanding tubs with floor- or wall-mounted fillers.
Toilet Installation & Relocation
Replacing a toilet in the same spot is straightforward and included in our fixture installation service. Moving a toilet requires rerouting drain lines, which could mean cutting through concrete or floors, placing the flange at the correct finished floor height, extending the soil stack connection, and ensuring proper venting. This work needs permits and inspections, which we manage for you.
We install a range of toilets: standard height, comfort-height ADA, wall-mounted, and dual-flush models. If you’re adding or remodeling a bathroom, it's a good opportunity to check your water heater capacity to handle the extra hot water demand. Accessibility upgrades, like grab bar blocking or curbless showers, are best planned with us early so we can coordinate with your contractor before drywall goes up.
Vanity & Sink Plumbing
Whether you’re going from a single to double sink, switching from a pedestal to vanity, or moving a vanity across the room, we handle supply and drain adjustments. Adding a second sink means extending supply lines and deciding on shared or individual P-traps depending on your setup. Changing vanity size often requires repositioning drain stub-outs and supply valves.
We install faucets, drains, supply lines, and P-traps as part of vanity setup, and swap out old gate-style shutoff valves with modern quarter-turn ball valves while the cabinet is accessible — an upgrade that prevents future leaks and water damage. We also manage drain and P-trap connections if the remodel changes pipe layouts.
Full Rough-In for New Bathrooms & Additions
Building a new bathroom, whether it’s a basement finish, half bath, or master suite addition, involves complete rough-in plumbing. That means running supply lines from the nearest water main, tying drains into your home’s existing stack or building drain, installing vent pipes to code, and setting floor flanges at finished floor level. Permits and inspections are part of this process, and we work closely with your general contractor to keep everything on schedule.

Key Tips for a Smooth Bathroom Plumbing Remodel
- Pick fixtures before plumbing rough-in: Pipes need to match the exact dimensions of toilets, tubs, and valves you choose.
- Keep fixture placement when possible: Relocating plumbing can add significant labor costs.
- Upgrade shutoff valves while walls are open: It’s cheaper and prevents leaks later.
- Check your water heater: Big tubs or extra showers might require a larger heater to keep you comfortable.
- Plan for permits early: Scheduling inspections affects your contractor’s timeline, so involve your plumber early.
Bathroom Remodeling FAQs
If you’re just swapping out fixtures in the same spot, usually no permit is needed. But if you move or add any drain lines, vents, or supply piping, permits are required by most local codes in Downers Grove. We’ll take care of obtaining permits and scheduling inspections to keep your project compliant. Skipping permits can cause serious issues down the line with insurance or home sales.
Yes, moving fixtures is possible but includes rerouting drain lines, vent pipes, and supply lines. This often means cutting concrete or floor joists to access pipes.

As soon as you start planning, especially before walls come down or go up.
