Bathroom Plumbing Remodeling Services in Spring Valley, IL
Underneath that new tile or fresh paint, your bathroom’s plumbing does the heavy lifting. If it’s not installed correctly, you might not notice until slow drains, hidden leaks behind walls, or inconsistent water temperatures throw a wrench in your routine. The difference between a bathroom that runs trouble-free for decades and one that gives you headaches starts with proper plumbing before the walls go up. If you find water damage when tearing out walls during your remodel, give us a call — leak detection and repair during this phase prevents costly surprises down the road.
When you reach out at 779-217-8459 for your bathroom project, we approach it like this: For straightforward updates like replacing faucets, toilets, or showerheads in the same spots, we can usually finish the plumbing in a day. But if you’re changing the layout — moving your toilet, swapping a tub for a walk-in shower, or adding a double vanity — this means rough-in work with new drain, vent, and supply lines that needs proper permits and inspections. We take care of all that.
I always advise homeowners: pick your fixtures before we set rough-in dimensions. Toilets, shower valves, and tub fillers all have different spacing needs. Deciding early prevents the hassle and expense of adjusting plumbing after the fact because a fixture won’t fit where it was planned.
Our Bathroom Plumbing Services
Shower & Tub Plumbing
Installing shower valves is a key part of bathroom rough-in. The valve must be set at the correct height and depth, with supply lines sized properly for steady pressure. We install pressure-balancing valves as required by Illinois code to prevent temperature spikes, thermostatic valves for consistent water temperature, and multi-port valve systems for rain showers, body sprays, and handhelds.
Tub-to-shower conversions are more involved: cutting the floor for a new drain, relocating or installing the shower pan drain with correct slope, prepping the floor for waterproofing, and rerouting supply lines from the tub filler to the new valve location. We’ll walk you through the full process and timeline before starting. We also handle freestanding tub setups, including supply rough-in for floor- or wall-mounted fillers.
Toilet Installation & Relocation
If you’re replacing a toilet in the same spot, that’s a simpler job we cover under our fixture installation services. Moving a toilet to a new wall or location involves rerouting the drain line, which may include cutting concrete or subfloor, installing the new flange level with the finished floor, extending or rerouting the soil stack, and ensuring proper venting. This requires permits and inspections before finishing the floor and walls.
We install all types of toilets: standard height, comfort or ADA height, wall-mounted, and dual-flush models. If you’re adding a new bathroom or upgrading, it’s also a good chance to check if your water heater can handle the extra hot water demand. Planning accessibility upgrades like grab bar blocking or curbless showers? Let us coordinate with your contractor early to install necessary wall blocking.
Vanity & Sink Plumbing
Whether you’re switching from a pedestal sink to a vanity, adding a second sink, or moving your vanity entirely, we handle the necessary drain and supply adjustments. Adding a sink means extending hot and cold lines and splitting the drain into shared or individual traps depending on your design. Changing vanity size usually requires adjusting stub-out heights and drain locations to fit the cabinet.
We install faucets, drain assemblies, supply lines, and P-traps as part of the job. While the cabinet is open, we recommend upgrading old gate valves to modern quarter-turn ball valves to prevent future leaks. We also take care of drain cleaning and P-trap tweaks as needed during rough-in.
Full Rough-In Plumbing for New Bathrooms & Additions
Adding a new bathroom—like finishing a basement, installing a half bath, or building an en-suite—involves complete plumbing rough-in work. This includes running supply lines from the closest main, connecting drains to the existing stack or building drain, installing vent pipes through the roof or tying into existing vents, and setting floor flanges at the finished floor height. All of this requires permits and inspections before walls and floors are closed. We work closely with your GC and manage inspection scheduling to keep your project on track.

- Upgrade old valves now: Replace worn shutoffs while walls and cabinets are open to prevent leaks later.
