Bathroom Plumbing Remodels in Robbins, IL
When remodeling a bathroom, the plumbing behind the scenes is what keeps everything running smoothly for years. If the water lines aren't correctly sized or the drain pipes aren’t correctly pitched during rough-in, you might notice slow drains, leaks hidden behind walls, or inconsistent shower temperatures down the road. Proper plumbing installation before drywall goes up is crucial to avoid headaches later. If you happen to uncover moisture damage in your existing walls during demo, give us a call — detecting leaks at this stage lets us fix problems before they cause bigger damage.
Calling 708-726-9658 to discuss your bathroom needs means getting a team that understands your project. A simple fixture update—installing a new faucet, toilet, and showerhead in the same spots—is a quick, one-day job we handle regularly. But if you’re rearranging the layout, moving the toilet, replacing a tub with a walk-in shower, or adding a double vanity, this requires rough-in plumbing changes that involve permits and inspections. We take care of all of it from start to finish.
I always advise homeowners to select their fixtures before the rough-in starts. Toilets, shower valves, and tub fillers each have specific rough-in measurements. Locking in your selections early helps us set pipe locations correctly the first time, avoiding costly adjustments later on.
Our Bathroom Plumbing Services
Shower & Tub Plumbing Installation
Installing shower valves is a key part of bathroom rough-in. We position your valve at the right height and depth so the trim fits perfectly and connect it with properly sized supply lines to maintain strong water flow. We install pressure-balance valves (which Illinois code requires for showers and tub/shower combos to prevent scalding), thermostatic valves for precise temperature control, and multi-function valve systems to handle rainheads or body sprays.
For conversions like swapping a tub for a walk-in shower, we core the floor to add a new drain line, set the shower pan correctly on a sloped floor, and reroute plumbing from the tub faucet to the shower valve. We’ll explain the scope and timeline so you know exactly what to expect. We also install plumbing for freestanding tubs, including supply piping for floor- or wall-mounted fillers.
Toilet Installation and Relocation
If you’re replacing a toilet in the same spot, that’s a quick fixture install (see our faucet and fixture installation service). Moving the toilet to a different wall or spot means rerouting drain lines, which may involve cutting into the concrete or floor joists, setting the flange at the right height, extending the soil stack vent, and ensuring proper venting for drainage. This work requires permits and inspections.
We handle installation of all types: standard height, comfort-height ADA models, wall-mounted toilets, and dual-flush systems. If you’re adding a bathroom or upgrading hot water needs, we can also advise on whether your water heater can handle extra demand. If your remodel includes accessibility upgrades like grab bars or curbless showers, coordinating plumbing and framing with your contractor early on makes the process smoother.
Vanity and Sink Plumbing
Whether you’re going from a single sink to a double, switching to a pedestal sink, or relocating a vanity, we adjust water supply lines and drain piping accordingly. Adding a second sink means splitting the drain into separate P-traps or a shared one depending on the setup, and extending hot and cold supply lines. If vanity dimensions change, we’ll move drain stub-outs and supply valve locations to match.
We install faucets, drains, supply hoses, and P-traps during vanity installation. While the cabinet’s open, we recommend upgrading any old gate valves to modern quarter-turn ball valves — it’s a common source of slow leaks under sinks. When changing drain locations, we also manage drain line and trap connections as part of rough-in.
Full Rough-In Plumbing for New Bathrooms & Additions
Building a new bathroom in your Robbins home—finishing a basement bath, adding a half bath, or putting in an en-suite—requires complete rough-in plumbing. We run supply lines from your nearest accessible main water line, connect drain lines into your existing stack or main building drain, install vent pipes that exit through the roof or tie into existing vents, and set floor flanges at the proper finished floor height. This phase includes permits and inspections before drywall goes up. We coordinate with your contractor and manage inspections so your project stays on track.

Tips for a Trouble-Free Bathroom Project
- Pick all fixtures before rough-in: Pipe locations depend on your exact toilet, tub, and valve models
- Keep fixtures in the same spot if possible: Moving pipes typically adds significant labor costs

- Confirm water heater size: Additional tubs or showers may require a larger unit—ask us for advice
- Plan for permits early: Permitting affects inspection scheduling and your contractor’s timeline
Common Questions About Bathroom Remodeling Plumbing
If you’re just replacing fixtures in the same location, you typically don’t need a permit. But any work that involves moving or adding drain or supply lines, or changing venting, usually requires a permit here in the Robbins area. We handle all permitting and inspections, so you can be confident everything is done by code and inspected properly. Skipping permits can cause issues with insurance and your home’s resale value.
Yes, we can relocate toilets or showers. This involves rerouting drain pipes—which often means cutting subfloor or concrete—extending vent pipes, and running new supply lines. It’s more labor-intensive than same-location replacements, but it lets you change your bathroom layout to fit your needs. We’ll provide a detailed quote for the plumbing work so you can plan accordingly.
The sooner the better—ideally before walls come down or are closed back up. Early involvement means we can help you understand exact rough-in measurements for your fixtures, what’s possible with your existing drain and vent stack, and how permitting will factor into the schedule. Waiting until after demolition can cause scheduling conflicts and rushed plumbing decisions.
