Expert Bathroom Plumbing in Naperville, IL
Bath plumbing might be hidden behind walls, but if it’s installed wrong, problems surface later — slow drains, leaks behind tile, or inconsistent shower temperatures. Getting everything perfect during rough-in is crucial to avoid headaches down the road. If you uncover signs of water damage behind walls, call us right away — leak detection during your remodel can catch issues before they're permanently concealed.
When you reach out to us at 331-226-1543 for your remodel, here’s the process: if you're just swapping out fixtures like a faucet, toilet, and shower head in their current spots, we can often finish that in a day. If you’re switching things around—moving the toilet, upgrading a tub to walk-in shower, adding a vanity sink—that calls for plumbing rough-in including drain, supply, and vent changes which require permits and inspections. We cover both types of projects .
I always advise my customers to pick their fixtures before we set any rough-in dimensions. Every toilet model, shower valve, and tub filler demands specific measurements. Finalizing your choices early on prevents costly adjustments later if the rough-in doesn’t match the fixture’s specs.
Our Bathroom Plumbing Services
Shower & Tub Plumbing
Installing shower valves is a delicate job. We position the valve at the exact height and depth so it aligns perfectly with your tile or wall finish. Illinois code requires pressure-balance valves in showers and tub/shower combos to prevent sudden temperature changes, and we also install thermostatic valves for consistent temperature control, plus multi-outlet systems for rain heads, body sprays, and handhelds.
When converting a tub to a shower, the process includes coring the floor for the new drain, making sure drain slopes are precise, prepping the shower floor for waterproof liners, and rerouting water supply lines from the tub filler to the new valve location. It’s a sizable project, and we’ll review the timeline and details with you upfront. We also take care of freestanding tubs by running supply lines for floor- or wall-mounted fillers.
Toilet Installation & Relocation
Replacing a toilet in the same spot is straightforward—check out our fixture installation service. Moving a toilet means rerouting drain pipes, cutting into the floor or concrete slab as needed, placing a new flange at the correct height, rerouting vent pipes, and extending the soil stack connection. This work requires permits and inspections before closing walls or floors.
We install all types: standard, comfort-height (ADA compliant), wall-hung, and dual-flush toilets. Adding a bathroom or upgrading your existing system? It’s a good time to check if your water heater can meet the extra hot water need. If accessibility is part of your remodel — like grab bars or barrier-free showers — we’ll coordinate with your GC to arrange blocking in the walls before drywall goes up.
Vanity & Sink Plumbing
Whether you’re switching from a single to double sink, swapping a pedestal for a vanity, or moving the vanity entirely, we handle the plumbing adjustments. Adding a second sink means running extra hot and cold lines and adjusting drain connections to one or two P-traps depending on your setup. Changing vanity size usually means repositioning supply stub-outs and drain lines to fit.
As part of vanity installation, we connect faucets, drains, supply lines, and P-traps. We also upgrade old gate-style shutoff valves to modern quarter-turn ball valves while the cabinet is open — a smart move since failing shutoffs are a common source of under-sink leaks. If your remodel changes drain locations, we also manage drain and P-trap hookups as part of the rough-in.
Complete Rough-In for New Bathrooms & Additions
Adding a new bathroom — whether it’s a basement finish, half bath, or master suite — requires full plumbing rough-in: running supply lines from the nearest main, tying drain lines into the existing sewer or building drain, installing vents through the roof or connecting to existing vents, and setting floor flanges at the finished floor height. This stage requires permits and inspections before walls are closed. We work closely with your GC and set inspection appointments to keep your project on track.
