Bathroom plumbing services route hot and cold supply lines to toilets, sinks, showers, and bathtub fixtures, connect drain-waste-vent piping, and correct low-pressure or slow-draining conditions that compromise daily use. Bonded Plumbworks’ licensed plumbers work with Uponor AquaPEX supply lines, Charlotte Pipe Schedule 40 PVC drain systems, and Delta MultiChoice or Moen Posi-Temp pressure-balancing valves on every shower and tub installation.
What Is Bathroom Plumbing
Bathroom plumbing is the branch of residential plumbing that supplies water to and removes wastewater from bathroom fixtures including toilets, sinks, bathtubs, showers, and bidets. A properly designed bathroom plumbing system includes hot and cold water supply lines sized for adequate flow, individual fixture shut-off valves, a drain-waste-vent system that prevents sewer gas from entering the home, and trap assemblies beneath each fixture. The applicable state building codes Plumbing section and the International Plumbing Code (IPC) govern minimum pipe sizes, vent requirements, and fixture spacing for bathroom installations.

- Your bathroom remodel requires relocating the toilet, vanity, or shower drain
- The toilet rocks on the floor, indicating a broken flange or deteriorated wax ring
- You need to add a bathroom to your home for a growing family or aging-in-place needs

Our Bathroom Plumbing Process
Step 1 — Bathroom Plumbing Assessment and Design
Our licensed plumber evaluates the existing bathroom plumbing infrastructure, including supply line sizes, drain pipe routing, vent stack connections, and fixture locations. For remodels and additions, we create a plumbing layout that meets applicable state building codes fixture spacing requirements and coordinates with your contractor’s floor plan. We identify whether existing supply and drain lines can support the new layout or require modification. Bathroom plumbing inspection gives you a live view of the problem before any work starts. You review the findings and approve the quote before any repair begins.
Step 2 — Rough-In Plumbing Installation
Rough-in work installs all supply lines, drain pipes, and vent connections behind walls and under floors before finish materials are applied. We install PEX-B or copper supply lines with dedicated shut-off valves for each fixture, Schedule 40 PVC or ABS drain piping at the required slopes, and wet-vent or individual-vent configurations per the IPC. A curbless shower drain requires a linear channel set flush with the finished floor, sloping the entire shower floor in one plane toward the drain rather than using a traditional center-point configuration. For wet-area wall surfaces, antimicrobial wet wall panels provide a grout-free, waterproof alternative to tile that eliminates mold-prone grout joints in bathroom plumbing installations. All rough-in work is pressure-tested at 80 PSI for supply lines and air-tested for DWV before the building inspector arrives.
Step 3 — Pressure Testing and Code Inspection
Before walls are closed, our plumber conducts pressure testing on all supply lines using a Reed or Wheeler hydrostatic test pump. Drain lines are tested with a 5 PSI air test and monitored for 15 minutes. We coordinate scheduling of the rough-in plumbing inspection with the local building department to ensure the work passes before the general contractor proceeds with drywall.
Step 4 — Fixture Installation and Trim-Out
After walls, floors, and tile work are complete, we return for the finish phase. This includes setting the toilet on a new wax ring or Danco HydroSeat gasket, installing the vanity faucet and P-trap assembly, connecting the shower valve trim kit, and mounting accessories. A comfort height toilet with a 16.5- to 18-inch rim height reduces strain on knees and hips, making it the standard specification for bathroom plumbing projects serving adults over 55. ADA sink installation positions the basin rim at 34 inches maximum with knee clearance beneath, connecting to the same supply and drain lines used in standard bathroom plumbing layouts. A bidet lift attaches to the existing toilet supply line and seat mounting points, adding personal hygiene functionality without requiring additional bathroom plumbing rough-in. Every fixture is tested for proper operation, leak-free connections, and adequate hot water delivery.
Step 5 — Final Testing and Warranty Walk-Through
We test every fixture for water pressure, drainage speed, and hot water temperature at the point of use. Anti-scald protection is verified on all shower and tub valves per state building code requirements. Comfort height toilet installation includes verifying the flange condition, setting the correct wax ring thickness for the flange height, and torquing brass anchor bolts to prevent rocking — a process that applies to every toilet set during bathroom plumbing trim-out. A curbless zero-threshold shower eliminates all entry barriers by sloping the entire bathroom floor plane toward a linear drain, requiring precise coordination between the shower pan and the surrounding bathroom plumbing floor system. We walk you through the completed bathroom plumbing, demonstrate shut-off valve locations, and provide warranty documentation.
