New Bathroom Plumbing Rough-In and Sewage System Installation in Tampa, FL 33611
Adding a new bathroom is one of the best upgrades you can make to a home, but it only pays off if the plumbing is designed and installed the right way. For a homeowner in Tampa, FL 33611, we were called in to handle a complete plumbing rough-in and new sewage and water supply installation for a new bathroom space. Our job was to make sure every pipe, drain, and vent was laid out correctly, connected safely, and ready to pass inspection and perform reliably for years to come.
On this project, we installed new PEX water lines, PVC drains and vent piping, a sewage grinder pump system, and all of the plumbing connections for the tub, shower, toilet, vanity, water heater, and roof vent termination. We also handled the concrete cutting, trenching, and patching related to the plumbing work, leaving the system ready for rough-in and final inspections by the general contractor and the permitting authority.
Below is a walkthrough of what the homeowner needed, how we approached the installation, and what other homeowners in Tampa Bay can learn if they’re planning a similar project.

Customer Problem: Building a New Bathroom the Right Way
The homeowner in Tampa, FL 33611 was adding a new bathroom and needed a licensed plumbing team to design and install the full system from start to finish. The existing plumbing layout wasn’t set up to simply “tie in” a new bathroom. That meant:
- New hot and cold water lines had to be run to the new fixtures.
- New drains and vent piping had to be installed for proper flow and sewer gas control.
- A sewage grinder pump was needed to move waste from the new bathroom to the existing sewer line.
- The work had to be done through an existing slab, which meant careful concrete cutting and patching.
The homeowner supplied the sewage grinder pump, fixtures (tub, toilet, vanity, shower trim, water heater), and in coordination with a licensed electrician for the pump’s electrical connection. Our responsibility was the plumbing design and installation: everything from the underground rough-in to the final hook-ups, all within an agreed plumbing scope and price.
They also wanted clear expectations: what we would cover, what would be handled by their roofer and electrician, and what kind of warranty and support they could expect from us after the job was complete.
Inspection and Diagnosis: Planning the New Bathroom Plumbing Layout
With new construction or an addition like this in Tampa, FL 33611, the most important “diagnosis” happens at the planning stage. We spent our time up front confirming the layout and how everything would tie into the home’s existing system. That included:
- Fixture locations: Confirming the exact location of the tub, shower, toilet, vanity, and water heater so we could lay out drains and water lines precisely.
- Sewage pump placement: Identifying the best spot for the pump basin to receive waste from the bathroom and discharge to the existing sewer.
- Drain and vent routes: Planning how PVC drain and vent piping would run under the slab and up through the walls and roof.
- Tie-in points: Establishing where the new pump discharge would connect to the existing sewer line and where water supplies would tie into the home’s main system.
- Concrete access: Marking precise slab cuts for drains, the pump basin, and trenching routes so we removed only what was necessary.
We also walked through expectations with the homeowner, including:
- That we would use PEX A for the water lines and PVC for the sewage system.
- That our concrete finish would be functional (ready for flooring and finishes later), not decorative.
- That any roofing work around the vent penetration would be handled by their roofer after we ran the vent through the roof.
- That an independent general contractor would perform rough-in and final checks before the official codes inspection.
This kind of upfront planning helps avoid surprises once the concrete is cut and pipes are in the ground.
Repair and Service Process: Step-by-Step Rough-In and Installation
Once the layout and scope were confirmed, we moved into the actual installation. For this Tampa, FL 33611 project, our process followed a clear sequence to keep things clean, safe, and code-compliant.
1. Concrete Cutting, Trenching, and Access
Because this was a slab-on-grade home, we needed to access the space below the concrete for drains and the sewage pump. We:
- Marked all slab penetration points for the toilet, tub/shower, vanity drain, and pump basin.
- Cut the concrete at those locations and along the paths where trenches were required.
- Trenched to allow proper slope on the drain lines and to run the grinder pump discharge line.
The homeowner assisted by handling the dirt trenching around the outside of the house where needed for sewer line routing, which helped keep the project efficient and within the agreed plumbing scope.
2. Installing PVC Drains, Vents, and Sewage Grinder Pump System
With access open, we installed the PVC waste and vent system and the sewage grinder pump components. This included:
- Setting the pump basin at the correct depth and location.
- Connecting the owner-supplied sewage grinder pump inside the basin.
- Running PVC discharge piping from the pump to the existing sewer line.
- Installing a check valve and required pump-side plumbing components to prevent backflow into the basin.
- Running PVC drain lines from the toilet, tub/shower, vanity, and other fixtures to the basin or main drain as designed.
- Installing vent piping and running it up through the structure to the roof for proper air movement in the system.
We handled all plumbing-side venting and roof penetration. The roofer’s responsibility was to flash and seal around that vent penetration afterward to maintain a watertight roof.
3. Running New PEX Water Supply Lines
Next, we installed the hot and cold PEX A water supply lines for the new bathroom. This step covered:
- Running dedicated PEX lines from the home’s main supply to each new fixture location.
- Installing new angle stops, valves, and ball valves where needed for shutoff and serviceability.
- Adding new faucet connectors and hose bibs within the agreed scope.
We designed the water system layout as part of the job so the homeowner would have balanced pressure, good flow, and future service access to key components.
4. Shower Liner and Bathroom Fixture Prep
For the shower, we installed the shower liner and prepared the drain setup according to the homeowner’s choice of drain:
- If a standard drain was used, we tied in the standard drain assembly provided by the homeowner.
- If a linear drain was selected, we connected the owner-supplied linear drain to our PVC system.
We also roughed in:
- The tub drain and water lines.
- The shower valve, riser, and showerhead location.
- The toilet flange location and drain.
- The vanity drain, water lines, and shutoffs.
- The water heater connections.
5. Backfilling, Concrete Pour-Back, and Cleanup
After all plumbing rough-in lines and the sewage grinder pump system were installed and checked, we:
- Backfilled trenches around the drain and discharge piping.
- Poured back concrete over the cut and trenched areas to restore the slab with a functional finish.
- Left the floor ready for the next trades (flooring, framing adjustments, etc.).
Our concrete patch is meant to be strong and serviceable, not decorative. Final floor finishes are handled by the appropriate trades afterward.
6. Final Fixture Connections and Inspection Readiness
Once the space was ready for finish work and the homeowner’s fixtures were on site, we returned to complete final connections for:
- Tub and tub trim.
- Shower valve, showerhead, and trim.
- Toilet connection.
- Pre-assembled vanity, faucet, and drain.
- Water heater connections.
- Sewage grinder pump plumbing connections and vent terminations.
The electrical connection for the grinder pump was completed separately by the homeowner’s licensed electrician, as electrical work is outside the plumbing scope.
We tested the plumbing system for leaks and proper flow and confirmed that the layout and installation were ready for the independent GC’s rough-in and final checks, followed by the official codes inspection.
Why This Plumbing Design and Grinder Pump Setup Works
For homes in Tampa, FL 33611, especially when adding a bathroom where traditional gravity drainage isn’t ideal, a properly installed sewage grinder pump system can make the project possible without major structural changes.
Here’s why this setup is effective and reliable when done correctly:
- Grinder pump function: The grinder pump macerates waste and pumps it under pressure through smaller-diameter discharge piping to tie into the existing sewer line, even if the new bathroom is lower than the main sewer connection.
- PVC drainage and venting: Correctly sloped PVC drain lines and properly sized and placed vent piping allow waste and water to move freely and prevent sewer gases from entering the home.
- PEX A water distribution: PEX is durable, flexible, and well-suited for new construction and remodels. Properly supported and connected, it gives stable water pressure and helps resist corrosion issues common in older piping materials.
- Check valve protection: The check valve on the pump discharge prevents sewage from flowing back into the basin, protecting the pump and the bathroom.
- Accessible shutoffs: New angle stops and ball valves give the homeowner and future technicians easy control during maintenance and repairs.
Taken together, this design supports good drainage, consistent water pressure, and long-term reliability, as long as the system is used properly and maintained when needed.
Pro Tips for Homeowners in Tampa Planning a New Bathroom
If you’re in Tampa, FL 33611 or nearby Tampa Bay communities and considering a new bathroom or major plumbing upgrade, a few practical steps can make the process smoother:
- Plan fixture locations early. Locking in your tub, shower, toilet, vanity, and water heater locations before we start cutting concrete helps avoid changes mid-project and keeps costs under control.
- Coordinate trades ahead of time. For projects like this, you’ll typically need a plumber, electrician, GC, and possibly a roofer and flooring contractor. Having everyone loosely aligned on timing makes the whole job move faster.
- Protect your home before work starts. We work cleanly and do our best to shield critical areas, but it’s smart to cover furniture, electronics, baby items, clothes, and food, and to move items away from vents and work areas.
- Expect some wall and ceiling openings. To run vent piping, water lines, or access tight areas, we sometimes have to open walls or ceilings. We keep openings as small as we reasonably can, but drywall and paint repair is usually handled by others after plumbing is complete.
- Ask about warranties and materials. For example, on this project, we used PEX A and PVC and provided a defined labor warranty on our work. Knowing exactly what’s installed in your home and what’s covered gives peace of mind.
- Consider future service access. When possible, we place valves and key components where they can be reached later. It’s worth a quick conversation during planning so you know where things are and how to turn them off if needed.

FAQ: New Bathroom Plumbing and Grinder Pump Installations
Do I need a sewage grinder pump for every new bathroom?
Not always. A grinder pump is usually recommended when the new bathroom is below or far from the main sewer connection and gravity alone can’t move waste effectively. In this Tampa, FL 33611 project, the layout made a grinder pump the practical solution. During a site visit, we’ll look at your existing plumbing and elevation to see what makes the most sense.
Who handles the electrical work for the grinder pump?
The plumbing scope covers the pump basin, plumbing connections, and discharge piping. A licensed electrician handles the electrical supply, wiring, and breaker configuration for the grinder pump. On this project, the homeowner’s electrician completed that portion after we finished the plumbing work.
What happens if my existing fixtures or valves can’t be reused?
Sometimes older showers, faucets, or valves are corroded, incompatible, or simply not in good condition. If we find that something can’t be connected safely or reliably, we’ll explain the issue on the spot and recommend replacement options. We won’t force a bad connection just to make something “fit.”
Will you repair drywall or paint after running new lines?
Our focus is on the plumbing itself. We do our best to keep openings as small and neat as possible, but we do not perform drywall or finish repairs. After inspections are complete, a drywall or general contractor can patch and finish the walls and ceilings as needed.
How clean will my home be during and after the project?
Plumbing work—especially through a slab—can be dusty and involve concrete cutting and trenching. We shield critical areas as best we can and clean up our work areas at the end of each day. We still recommend that you cover furniture and belongings and keep clear of the work area so our technicians can focus and stay safe.
Is there a warranty on this type of plumbing installation?
For this project, we provided a defined labor warranty on the plumbing scope, including the new piping and fixture connections. The specific terms can vary by project, but we’re always clear about what is covered before we start. Manufacturer warranties on fixtures and pumps are typically handled through the product manufacturers.
