New Home Plumbing
Complete plumbing systems for new residential builds throughout St. George and Southern Utah.
- Supply and drain layout per approved plans
- Fixture locations coordinated with builder
- Hard-water-ready material selections
New home plumbing in St. George starts with a plan that matches your approved drawings and local code. MBR installs supply lines, drains, and vents sized for your home's layout and Southern Utah water conditions.
We coordinate fixture locations with your builder during framing so bathrooms, kitchens, laundry, and outdoor hose bibs are positioned correctly before drywall goes up.
Underground & Slab Plumbing
Foundation-stage plumbing that must be right the first time.
- Underground water and sewer lines
- Slab rough-in before pour
- Coordination with excavation and concrete crews
Underground plumbing is the first major plumbing phase on a new build. Supply lines, sewer connections, and slab penetrations must be placed precisely before concrete is poured. Mistakes here are costly to fix.
MBR works with your builder's schedule to complete underground and slab rough-in on time, whether your project connects to city sewer or requires a septic system on a rural lot.
Rough-In, Fixtures & Water Heaters
From framed walls to finished fixtures and hot water delivery.
- Wall and ceiling rough-in during framing
- Fixture and trim installation
- Tank and tankless water heater placement
After the slab, rough-in plumbing runs through walls and ceilings before insulation and drywall. This includes supply lines, drain/waste/vent (DWV) routing, and stub-outs for every fixture.
Finish work includes installing faucets, toilets, tubs, showers, and your water heater, sized and positioned for Southern Utah's hard water and your household's hot water demand.
Builder Coordination & Inspections
Keeping your new construction timeline on track.
- Schedule coordination with general contractors
- Inspection-ready installs at each phase
- Clear communication on scope and changes
The best new construction experiences come from a plumber who communicates timelines, shows up when scheduled, and passes inspections without rework. MBR coordinates with builders throughout St. George, Washington, and Hurricane on residential projects.
We stage our work to match your construction timeline: underground before slab, rough-in during framing, trim after drywall. We ensure each phase is ready for inspection before the next trade moves in.

When should a new construction plumber start on my build?
Plumbing begins underground before the slab pour, then rough-in during framing, and finish work after drywall. MBR coordinates timing with your builder at each phase.
Do you install water heaters on new construction?
Yes. Water heater installation, tank or tankless, is part of our new construction scope. We size units for your home and Southern Utah hard water.
