Plumbing for Bathroom Remodels in Markham, IL
Bathroom plumbing is the backbone of a successful remodel — it operates behind the walls, out of sight, but if done poorly, issues like slow drains, hidden leaks, or inconsistent shower temperatures can surface weeks or months later. Proper rough-in plumbing sets the foundation for a bathroom that performs reliably for decades. If you uncover signs of moisture damage behind walls during your remodel, give us a call — spotting leaks early with our leak detection services can save you from expensive repairs down the line.
When you reach out at 708-729-6560 for your bathroom update, here’s how we approach the job: if it’s a basic refresh—like swapping out faucets, toilets, or showerheads in their current spots—that’s usually a quick, one-day install. But if you’re rearranging the layout — moving the toilet, swapping a tub for a walk-in shower, or adding another sink — that requires careful planning for rough-in plumbing including drains, vents, and supply lines, plus permits and inspections. We manage all of it.
One tip I always share: lock in your fixtures before we start rough-in. Toilets, shower valves, and tub fillers all have different rough-in specifications. Picking them early keeps us from having to redo plumbing work later because your fixtures don’t match the rough-in dimensions.
Our Bathroom Plumbing Services
Shower and Tub Plumbing
Installing shower valves is a crucial part of any bathroom remodel. Valves must be positioned at the correct height and depth to work with your finished walls and meet Illinois plumbing codes, including installing pressure-balance valves to protect against scalding. We also install thermostatic valves for consistent temperature control and multi-outlet valves for rain showers, body sprays, or handheld units.
Converting a tub to a shower involves new drain installation with proper floor pitching, creating a waterproof shower base, and rerouting water supply from the tub faucet to the new shower valve. We go over the full plan and schedule before starting. We also plumb freestanding tubs with floor or wall-mounted fillers.
Toilet Installation and Relocation
Replacing a toilet in the same spot is straightforward and included in our fixture installation services. Moving a toilet requires rerouting drain pipes, cutting into floors or concrete as needed, fitting new flanges at the right height, extending the soil stack, and adjusting venting. This work is permitted and inspected to ensure everything’s up to code.
We install all types—standard, comfort height, wall-hung, and dual-flush models. If you’re adding a new bathroom or upgrading, it’s a good time to check if your water heater can handle extra hot water demand. Planning accessibility features? We can coordinate grab bar blocking and curbless showers with your GC before drywall goes up.
Vanity and Sink Plumbing
Whether you’re shifting from one sink to two, switching from a pedestal to a vanity, or moving your vanity entirely, we handle all supply line and drain modifications. Adding a second sink often means running new supply lines and configuring drains with shared or separate P-traps depending on your setup. Changing vanity dimensions can require adjusting plumbing stub-out heights and drain locations.
We install faucets, drain assemblies, supply valves, and P-traps as part of your vanity setup. While cabinets are open, we recommend swapping out old gate valves for modern quarter-turn ball valves to prevent future leaks—it’s a simple upgrade that prevents costly water damage.
If your remodel shifts drain locations, we’re equipped to manage drain and P-trap connections during rough-in.
Full Rough-In for New Bathrooms and Additions
Installing a new bathroom in your Markham home—whether it’s a basement finish, half bath, or en-suite—means full rough-in plumbing work. That includes running supply lines from the closest main, tying drain lines into existing stacks or building drains, installing vent stacks through the roof or connecting to existing venting, and placing floor flanges at the proper height. This phase requires permits and inspections before walls close, and we coordinate with your general contractor to keep the project on track.

Tips for a Trouble-Free Bathroom Remodel
- Choose your fixtures before rough-in: Each fixture has specific rough-in requirements. Confirm selections early to avoid costly changes.
- Keep plumbing layouts stable when possible: Moving pipes raises labor costs—stay put if you can.
- Upgrade shutoff valves while walls are open: Old valves fail more often and cause leaks—replace them now.
- Check your water heater’s capability: Extra fixtures, like soaking tubs or additional showers, may require a larger heater (learn more).
- Plan for permits early: Permits and inspections affect timing—include your plumber in the schedule from day one.
Bathroom Remodeling FAQs
For simple fixture swaps in the same spot, most municipalities around Markham don’t require a permit. But any work that alters drain lines, vent pipes, or adds new supply lines generally needs a permit. We handle all the paperwork and inspections so you don’t have to worry about it. Skipping permits can cause headaches down the line, especially when you sell your home.
Yes, but it’s a bigger job. Moving a toilet or shower means rerouting drain and vent pipes, which can involve cutting into concrete or subflooring. It costs more than replacing fixtures in place but allows you to customize your bathroom layout. We’ll give you an accurate quote based on what you want to do.
As soon as possible—ideally before demolition so we can advise on rough-in requirements, what’s possible with existing plumbing, and help keep your timeline on track. Calling a plumber last minute after demo often leads to delays and compromises on pipe placement.
