Bathroom Plumbing Services in Oak Forest, IL
When remodeling a bathroom, the plumbing work hides behind the walls but plays a huge role in long-term performance. A poorly done rough-in can cause slow drains, leaks behind walls, or shower valves that don’t deliver consistent temperatures. Getting the plumbing right from the start is what keeps your bathroom running smoothly through all seasons here in Oak Forest, whether it’s the freezing cold snaps or humid summers.
If your remodel exposes water damage or mold behind walls, give us a call. Our leak detection services during the remodel help catch hidden issues before closing things up, saving you headaches later. When you reach out to us at 708-729-6139, here’s how we approach your project: a simple upgrade swapping out the faucet, toilet, and showerhead in their current spots typically takes a day. But if you’re shifting the layout — moving toilets, removing tubs for showers, adding sinks — that’s a more involved rough-in with drain and supply plumbing that will require permits and inspections, and we make that process easy for you.
I always advise homeowners to pick out their fixtures before we set any rough-in dimensions. Fixtures like toilets and shower valves have different installation depths and rough-in distances, and locking those down early avoids costly rework. Oak Forest homes, especially older ones, often have tighter spaces, so precise planning saves time and money.
Our Bathroom Plumbing Services
Showers & Tub Plumbing Installations
Installing shower valves is a key step. We set them to code at the right height and depth behind the finished wall, using appropriately sized supply lines to ensure steady water flow. We install pressure-balance valves, which Illinois plumbing code requires to prevent sudden scalding, plus thermostatic valves for better temperature control. For luxury setups, we handle multi-outlet valve systems that supply rain shower heads, body sprays, and hand-held showers.
Converting a tub to a shower involves cutting into floors for new drains, repositioning the shower pan drain with correct slope, raising the floor to fit waterproof liners, and running supply lines from the original tub filler location to the new valve. It’s a fairly big job, so we review the full details and timelines with you before starting. We also install freestanding tubs, setting up supply lines for floor or wall-mounted tub fillers.
Toilet Installation and Moving
Replacing a toilet in the same spot is usually straightforward — check out our fixture installation service for that. Moving a toilet to a new wall or spot takes more work: rerouting drain lines often means cutting into concrete or subfloor, fitting the new flange at the right height, extending or changing soil stack connections, and making sure vents are properly configured. Since this work requires permits and inspections, we take care of all that for you.
We fit all toilet types — from standard and comfort height (ADA) to wall-hung and dual-flush models. If your remodel adds a bathroom or upgrades fixtures, it’s a good time to check if your water heater can keep up with the extra hot water demand. If you’re adding accessibility features like grab bars or a curbless shower entry, we coordinate with your GC to install blocking before drywall goes up.
Vanity and Sink Plumbing
Whether you’re going from a single sink to a double, switching from a pedestal to a vanity, or moving your vanity entirely, we adjust all supply and drain connections. Adding a second sink means extending hot and cold lines and either sharing or splitting drains with separate P-traps depending on your setup. Changing the size of the vanity requires tweaking stub-out heights and drain locations to match the cabinetry.
We install faucets, drains, supply lines, and P-traps as part of vanity work. While the cabinet is open, we recommend upgrading old gate valves to modern quarter-turn ball valves to avoid future leaks. If drain locations are changing, we also handle drain line and P-trap connections to make sure everything flows smoothly.
Full Rough-In for New Bathrooms and Additions
Building a new bathroom in your Oak Forest home—like finishing a basement, half bath, or master suite—means a complete plumbing rough-in. We run supply lines from the closest main, connect drains to the existing stack or building drain, install vent pipes through the roof or tie into existing vents, and set floor flanges at proper height. This stage requires permits and inspections before closing walls. We coordinate inspections and timing with your GC to keep things moving smoothly.

Tips for a More Efficient Bathroom Remodel
- Choose fixtures before rough-in: Different fixtures like toilets and shower valves require specific rough-in dimensions — lock these in ahead of plumbing work
- Keep plumbing locations the same if possible: Moving fixtures adds labor and expense compared to replacing in place
- Upgrade shutoff valves now: Replacing old gate valves with quarter-turn ball valves while walls are open saves water damage trouble down the road
- Check your water heater size: If adding a soaking tub or extra shower, make sure your water heater can handle the load
- Plan permits early: Rough-in inspections can impact your timeline — involve your plumber early to schedule accordingly
