Reliable Bathroom Plumbing Remodeling in Ottawa, IL
Behind the scenes of any bathroom renovation lies the plumbing — unseen yet critical. If that’s not installed correctly, issues like slow drains, hidden leaks, or inconsistent shower temperature can emerge long after the job is done. Quality plumbing before drywall and tile go in is what guarantees your bathroom functions smoothly for decades. If you ever peel back walls and spot signs of water damage, reach out — catching leaks early with our leak detection saves you headaches down the road.
Give us a call at 815-324-1310 with your bathroom remodel plans. For simple fixture upgrades — swapping faucets, toilets, and showerheads in their existing spots — we usually finish in one day. But if you’re reconfiguring layouts, like moving the toilet, switching a tub to a walk-in shower, or adding a second sink, that involves rough-in plumbing with supply, drain, and vent line work that requires permits and inspection. We handle all aspects smoothly.
I always advise homeowners: lock in your fixtures before we start any rough-in plumbing. Different toilets and shower valves need specific rough-in spacing. Picking your fixtures early prevents costly adjustments if the rough-ins don’t match the new equipment’s specs.
Our Bathroom Plumbing Services
Shower & Tub Plumbing Installation
Shower valve placement is a key part of the rough-in process. It must be hung at the right height and depth behind the finished wall, connected to supply lines sized properly to keep good flow. We install pressure-balance valves—required in Illinois—to protect against scalding, thermostatic valves for exact temperature control, and multi-outlet setups for rain heads, body sprays, and handheld showers.
Converting a tub into a shower involves drilling through the floor for a new drain, repositioning or setting up a shower pan drain with correct slope, building up the shower base for waterproof membrane, and rerouting water supply from the tub filler to the shower valve. This is a bigger job; we’ll explain the full scope and timeline before starting. We also install supplies for freestanding tubs, whether floor-mount or wall-mount.
Toilet Installation and Moving
Replacing a toilet in its current spot? We offer quick fixture installation through our fixture services. Moving a toilet means rerouting the drain pipe—cutting into concrete or subfloor as needed—setting a new flange at the proper height for finished flooring, extending or rearranging the soil stack connection, and ensuring venting meets code. Permits and inspections are part of this work.
We install all types: standard, comfort height, wall-mounted, and dual-flush toilets. Adding or upgrading bathrooms? We can check if your water heating system has the capacity to handle increased demand. Accessibility upgrades like grab bar blocking or curbless showers? Let’s plan that early so we coordinate with your GC on wall blocking before drywall goes up.
Vanity and Sink Plumbing
Whether converting a single sink to double, switching from pedestal to vanity, or relocating the vanity, we take care of supply line extensions and drain modifications. Adding a second sink usually means splitting the drain into shared or individual P-traps and extending hot and cold water lines. Adjusting vanity size might also require repositioning pipe stub-outs to fit the new cabinetry.
We handle faucet installation, drain assemblies, supply connections, and P-trap setup. While cabinet areas are open, we recommend replacing old gate-style shutoff valves with modern quarter-turn ball valves to avoid future leaks. If the remodel changes drain locations, we cover drain and P-trap connections as part of the rough-in work.
Complete Rough-In Plumbing for New Bathrooms or Additions
Installing a new bathroom in your Ottawa home—whether finishing a basement half bath, adding a guest bath, or creating an en-suite—means full plumbing rough-in: running supply lines from the nearest main, tying drain lines into the existing stack or main building drain, installing vent pipes through the roof or connecting to current venting, and setting floor flanges at the right height. These steps require permits and inspections before drywall installation. We work closely with your GC and handle scheduling inspections as part of our standard process.

Tips for a Successful Bathroom Remodel
- Finalize your fixtures first: Exact rough-in dimensions depend on the fixtures chosen—lock these in ahead of plumbing
- Stick to existing layouts if possible: Moving plumbing lines adds significant labor and cost
- Consider valve upgrades now: Replace aging shutoffs while walls are open to prevent leaks later
- Evaluate your water heater size: Extra showers or large tubs may need bigger or more efficient water heaters (water heater services)
- Plan permits early: Plumbing inspections affect your contractor’s schedule, so involve us early
Bathroom Remodeling Questions
If you’re just swapping out faucets or toilets in the same spots, you usually don’t need a permit. But any move, addition, or modification of drain, vent, or supply lines will require a permit in Ottawa. We take care of all the paperwork and inspections, so you don’t have to worry about getting flagged later. It’s important for insurance and resale value that plumbing work is permitted.
Yes, that’s possible, though it requires rerouting drain pipes—cutting concrete or subfloor if needed—relocating vent pipe connections, and extending supply lines. This adds cost compared to keeping fixtures where they are, but it gives you full control over your bathroom layout. We’ll provide a detailed quote so you can decide if it fits your budget.
As soon as you’re planning the remodel, ideally before demo or opening walls. That way, we can advise on rough-in dimensions based on your fixture choices, evaluate existing drain and vent stack locations, and coordinate permits and inspections with your general contractor. Waiting until last minute often leads to scheduling conflicts or rushed decisions on pipe placement.
