Typical bathroom remodel plumbing scope
The plumbing trade on a bathroom remodel usually handles:
Demolition and removal. Disconnect and remove existing toilet, vanity, sink, shower or tub. Cap supply and drain lines for safety during demo. On full gut projects, sometimes also remove existing supply and drain lines back to a clean starting point.
Drain relocation. If the new layout moves any fixture, drain plumbing has to follow. Most-relocated: toilets (each drain location moved means breaking floor or cutting joists), showers (especially in tub-to-shower conversions), vanity sinks (often moved as part of vanity size or layout changes). Coordinate with framing to ensure new drain runs have adequate slope and joist clearance.
Supply line relocation. New fixture locations need supply lines. We run PEX-A from the existing main lines or manifold to each new location, with shutoffs at every fixture.
Vent extensions. Plumbing fixtures need venting to function correctly (without venting, drain flow creates negative pressure that pulls water out of P-traps). Relocated fixtures often need vent extensions or new wet-vent configurations.
Multi-fixture installs. Double vanity sinks, master baths with multiple shower heads, freestanding tubs with floor or wall fillers. Each adds complexity to the rough-in and to the trim install.
Trim and final install. Faucets, toilets, shower trim, drain covers all installed after tile and drywall finish. Pressure and flow testing, fixture adjustments, leak check before sign-off.
Permits, code, and inspection coordination
Bathroom remodels that move plumbing need permits. Fulton County needs plumbing permits for any work that relocates drains, supplies, or vents. Permits aren't a hassle, they're a feature, because the resulting code inspection confirms the work meets safety and durability standards.
What we permit: anything moving drain, supply, or vent locations. What usually doesn't need permits: fixture-in-place swaps (replacing a toilet in the same location, swapping a vanity for one of the same configuration, replacing a shower trim kit). Borderline cases go through the permit office for clarification before work starts.
Inspection coordination: rough-in inspection happens before tile and drywall close up the walls. Final inspection happens after trim is installed. Both inspections need to pass for the permit to close. We coordinate timing with the inspector and the other trades on your project so neither step delays the overall schedule.
Coordinating with other trades on a remodel
Bathroom remodels involve multiple trades. The order of operations usually goes:
1. Demolition. Remove existing finishes, fixtures, and (sometimes) framing back to a clean starting point.
2. Framing changes. Carpenter handles wall additions, niches, blocking for fixtures and grab bars.
3. Plumbing rough-in. Our scope. Drains, supplies, vents, valve bodies all in place. Inspected before walls close.
4. Electrical rough-in. Electrician's scope. Outlets, switches, lighting circuits, exhaust fan, in-floor heat.
5. Insulation and drywall. Walls close. Mud and finish.
6. Tile. Floor tile, wall tile, shower surround. Coordination with plumbing on penetrations through waterproofing.
7. Finish carpentry and paint. Trim, doors, paint.
8. Plumbing trim. Our return visit. Toilet, vanity faucet, shower trim, drain covers all installed. Final testing and adjustment.
9. Final inspections. Permit close-out.
For homeowners managing the project directly (without a GC), keeping this order on track is the main challenge. For projects with a GC, our scope coordinates through them. Either way, our pieces are clearly defined and we communicate timing proactively.
Slab vs crawl space and remodel cost reality
The biggest cost driver in Alpharetta bathroom remodels, beyond fixture choices, is whether your home is slab-on-grade or crawl space. Drain relocation in slab homes needs breaking concrete; in crawl space homes the same work happens from below at lower cost.
Layout decisions for slab homes should consider this. Keeping toilet locations roughly where they are, even when changing vanity and shower locations, saves big cost. Conversely, moving a toilet six feet across the room means a concrete-breaking job under the floor.
For multi-bath projects we sometimes recommend doing the slab work for multiple bathrooms simultaneously, once we're set up to break and patch concrete, doing two baths together is more efficient than two separate projects.
Cost of this service in Alpharetta
Bathroom remodel plumbing scopes vary widely. The plumbing portion is usually 15–30% of total remodel cost. Pricing depends on whether fixtures move (drain and supply relocation) or stay in place (replacement only).
| Typical scope | Price range | Notes |
|---|---|---|
| Fixture-replacement-only plumbing scope | $1,450–$4,500 | no rough-in changes |
| Light remodel (one fixture moves) | $3,500–$8,500 | supply and drain relocation |
| Full remodel (multiple fixtures move) | $7,500–$18,500 | manifold and venting changes |
| Master bath remodel + addition | $12,500–$28,500 | new rough-in, often new venting |
What moves your project within the range:
- Whether fixtures move. Each relocation needs drain, supply, and sometimes venting work.
- Number of fixtures. Standard bath has 4 (toilet, sink, tub/shower, vent). Master bath often has 6+.
- Coordination with other trades. Tile, electrical, drywall all need to interlock with plumbing.
- Permit fees and inspections. Pulled at cost; typical residential bathroom remodel triggers 1–2 plumbing inspections.

Frequently asked
Do I need a permit for a bathroom remodel?
If you're relocating drains, supplies, or vents, yes. Fixture-in-place swaps usually don't need permits. We pull permits when scope needs and coordinate inspections.
How long does a bathroom remodel take?
Full gut renovation: usually 3–6 weeks elapsed time including all trades. Smaller scope (fixture upgrade, surround replacement): 1–2 weeks. Our plumbing portion is spread across the schedule, rough-in early, trim near the end.
Can I save money by reusing existing plumbing locations?
Yes, a lot. Especially in slab homes, keeping drain locations where they are avoids concrete work that can be a major cost driver. Smart layout decisions before demo can save a lot without limiting the design.
Do you work with my contractor or do I need to hire you separately?
Either works. On projects with a GC we coordinate scope and scheduling through the GC. On direct-homeowner projects we communicate directly with you and coordinate with other trades you've engaged.
Will inspections delay my project?
Usually no, we schedule inspections proactively to fit between trade phases. Rough-in inspection happens before walls close so it doesn't gate downstream work. Final inspection happens at the end and is usually same-day or next-day.
