Expert Bathroom Plumbing Remodels in Winthrop Harbor, IL
The hidden plumbing behind your bathroom walls is what keeps everything running smoothly, but if not done right, issues like slow drains, hidden leaks behind tile, or inconsistent shower temperatures can creep up weeks after the job’s done. Properly installed plumbing before your walls close is key to avoiding headaches down the road. If your remodel uncovers moisture damage or signs of leaks, give us a call — spot-on leak detection during remodeling can catch hidden problems before they cause bigger damage.
When you reach out to us at 224-524-1683 for your bathroom remodel, here’s our approach: if you’re only swapping out fixtures like faucets, toilets, or showerheads in the existing spots, we’ll take care of the installation quickly—usually within a day. But if your plan involves layout changes like moving the toilet, converting a tub to a walk-in shower, or adding a double vanity, that calls for rough-in plumbing work including pipe rerouting and vent adjustments that require permits and inspections. We handle both types of projects with equal care.
One piece of advice I always give: finalize your fixture choices before we set rough-in measurements. Toilets, shower valves, and tub fillers all have unique rough-in needs. Getting those details locked down early means you avoid costly rework due to mismatched pipe locations after framing.
Our Bathroom Plumbing Services
Shower & Tub Plumbing Installation
Installing shower valves accurately is critical to your bathroom’s function. We carefully position valves at the correct height and depth relative to your finished wall for smooth operation, using properly sized supply lines to maintain flow. Illinois code requires pressure-balance valves in showers and tub/shower combos to protect against scalding; we install those as well as thermostatic valves for consistent temperatures and multi-function valve systems for rain heads, body sprays, and handheld showers.
For tub-to-shower conversions, we core the floor to place the new drain correctly, ensure proper sloping for drainage, build up the floor for waterproof liners, and reroute supply lines from the tub filler to the new valve location. This is a detailed plumbing rough-in job—we’ll review every step with you before we begin. We also set up freestanding tubs, handling supply rough-ins for floor- or wall-mounted tub fillers.
Toilet Setup & Relocation
Toilets replaced in the same spot are a simple job—check out our fixture installation services for details. Moving a toilet to a new wall or different area takes more work: we cut through concrete or subfloor as needed, install a new flange at the right height, reroute or extend soil stacks, and make sure the venting system meets code. This work requires permits and inspections before you close walls and floors.
We install a variety of toilets including standard, comfort-height (ADA-compliant), wall-hung, and dual-flush models. If you’re adding a bathroom or upgrading, it’s a good time to check if your water heater can handle the additional demand. If accessibility is a priority, like adding grab bars or curbless showers, we coordinate with your contractor to make sure blocking is installed before drywall goes up.
Vanity & Sink Plumbing
Whether you’re upgrading from single to double sinks, swapping a pedestal sink for a vanity, or moving the vanity to a new location, we adjust supply and drain lines accordingly. Adding a second sink means extending hot and cold supply lines and managing drain connections with either shared or separate P-traps depending on your setup. Changing the vanity size often requires repositioning stub-outs and drain locations to align with cabinetry.
We install faucets, drains, supply lines, and P-traps as part of vanity setup. While the cabinet is open, we recommend upgrading old gate valves to modern quarter-turn ball valves to reduce the risk of leaks. If your remodel shifts drain locations, we also handle drain and P-trap connections as part of the rough-in.
Full Plumbing Rough-In for New Bathrooms & Additions
Building a new bathroom in your Winthrop Harbor home—whether a basement finish, half bath, or en-suite—means full rough-in plumbing. This includes running supply lines from the closest main supply, installing drain lines connected to existing stacks or the building drain, setting up vent pipes through the roof or tying into existing vents, and installing floor flanges at the correct finished floor height. We manage permits, inspections, and coordinate with your contractor to keep your project on track.

Bathroom Remodel FAQ
If you’re just replacing fixtures where they currently sit, permits usually aren’t necessary. But anytime you move or add plumbing lines, vents, or reshuffle pipe rough-ins, permits are required in Winthrop Harbor. We take care of getting those permits and making sure inspections happen on schedule. Skipping permits can cause trouble down the line with insurance claims or selling your home.
