Bathroom Plumbing Services for Remodels in Mount Prospect, IL
Good bathroom plumbing is invisible when done right — but if something’s off, it shows up in slow drains, water leaks behind walls, or inconsistent shower temps. That’s why we focus on proper pipe layout, venting, and valve placement before the drywall goes up. If you uncover moisture spots during demolition, our team can handle leak detection and repairs to stop hidden issues from causing bigger problems down the road.
When you reach out at 224-524-1247 for a bathroom project, we tailor our approach to your needs. A simple fixture swap — replacing a faucet, toilet, or showerhead in place — is usually done within a day. But if you want to rearrange the room, add sinks, or convert a tub to a shower, that means rerouting drains, vents, and supply lines, which requires permits and inspections. We manage all aspects so the plumbing passes muster.
I always advise homeowners to finalize their fixture picks before we set rough-in measurements. Toilets, valves, and tubs come with different spacing requirements, and locking those in early saves headaches and extra expenses later on.
Our Bathroom Plumbing Services
Showers & Tub Plumbing
Installing shower valves is one of the most important parts of bathroom rough-in. We position valves at the proper height and depth and connect them using appropriately sized hot and cold lines to ensure steady water flow. We work with pressure-balance valves — required by Illinois code to prevent scalding — thermostatic valves for temperature precision, and multi-outlet valve systems for features like rain heads and body sprays.
Converting a tub to a shower means cutting into the floor for a new drain, adjusting slopes for proper drainage, prepping for waterproof liners, and rerouting supply lines from the tub filler to the shower valve. It’s a big job, and we’ll go over every step and timing with you before starting. We also set up supply lines for freestanding tubs, whether the tub filler is floor-mounted or wall-mounted.
Toilet Installation & Relocation
If you're swapping out your toilet in the same spot, that’s a quick job covered under our fixture installation service. Moving a toilet means rerouting drain piping, cutting into concrete or subfloor as needed, installing a new flange at the right height for your floor finish, extending soil stacks, and making sure venting meets code. This plumbing work requires permitting and inspection before closing walls.
We fit standard models, comfort-height toilets, wall-hung designs, and dual-flush options. If you’re adding a bathroom or upgrading, it’s a good time to check if your water heater can handle the extra demand. Planning accessibility features like grab bars or curbless showers? We coordinate with your contractor to add wall blocking before drywall goes up.
Vanity & Sink Plumbing
Whether you’re upgrading from a pedestal sink to a vanity, switching from one-sink to two-sink vanity, or relocating the whole setup, we modify supply and drain lines accordingly. Adding a second sink means extending hot and cold lines and configuring P-traps correctly—sometimes shared, sometimes separate depending on the design. When changing vanity sizes, we'll adjust drain and supply heights to fit the new cabinetry.
We install faucets, drains, P-traps, and supply tubing as part of the install. While the cabinet is open, we recommend swapping out any old gate valves for modern quarter-turn ball valves to prevent leaks — a common source of under-sink water damage. Moving drains? We handle drain and P-trap connections as part of the rough-in work.
Complete Plumbing Rough-In for New Bathrooms & Additions
Building a new bathroom in your Mount Prospect home — whether finishing the basement, adding a half bath, or creating a master en-suite — requires full plumbing rough-in. That means tying into existing water mains, connecting drain lines to the building sewer, running vent pipes through the roof or joining existing vents, and installing floor flanges at the correct level. We handle permits, inspections, and work closely with your builder to keep the project on track.

Advice for a Hassle-Free Bathroom Remodel
- Pick fixtures before rough-in: Different models have varied rough-in specs, so lock those before pipes go in.
- Stick with existing layouts if possible: Moving drains or supply lines ups labor and material costs considerably.
- Upgrade valves while walls are open: Old shutoffs are prone to failure—replace them during the remodel to avoid leaks.
- Evaluate your water heater: Extra sinks, showers, or tubs may require a larger or more efficient water heater.
- Plan for permits early: Plumbing inspections impact project scheduling—include your plumber early to avoid last-minute issues.
Bathroom Remodeling Frequently Asked Questions
If you are just replacing fixtures in the same spots, generally no permit is required.
