When to bring in the pro
The rule is simple: anything behind the wall or under the floor is pro work. Here is the checklist.
- You are moving any fixture — toilet, sink, tub, or shower — from its current location.
- Converting a tub to a shower or adding a second sink.
- Galvanized or polybutylene supply lines exposed during demolition.
- An older home where the existing plumbing predates current code.
- Adding a bathroom or wet bar where no plumbing exists yet.
What remodel plumbing includes
From first layout to final fixture, this is what the plumbing phase includes.
- Rough-in plumbing: supply and drain lines run to the new fixture locations.
- Drain, waste, and vent layout verified for proper slope and venting.
- Fixture installation: toilets, sinks, faucets, showers, tubs, and dishwashers.
- Gas line work for relocated ranges, dryers, or fire features, where needed.
- Coordination with your general contractor on sequencing and inspections.
- Final trim-out, leak checks, and pressure testing before handoff.
Before the walls open
A little planning prevents the most expensive words in remodeling: 'while the wall is open anyway.'
Safe to do now
- Finalize your fixture layout before the plumber starts — changes mid-rough-in are expensive.
- Choose and purchase fixtures early so rough-in dimensions match.
- Photograph the open walls showing new pipe runs before drywall goes up.
- Keep a clear path and workspace for the plumbing crew during rough-in.
Stop — call a pro
- Do not close walls before the plumbing rough-in is inspected.
- Moving drain lines yourself — slope and venting rules are unforgiving.
- Setting a toilet or connecting a shower valve without checking the rough-in dimensions.
- Skipping permits on plumbing changes — it complicates future sales and insurance.
The process, step by step
Rough-in, inspection, close-up, trim-out: the rhythm of the job. The phases explained.
Plan review: the pro reviews your layout and flags what the plumbing will require — moves, venting, and code upgrades.
Rough-in: new drain, supply, and vent lines are run and left ready for inspection before walls close.
Inspection: the rough-in is pressure-tested and inspected per local code.
Finish: after walls and tile, fixtures get set, connected, sealed, and tested.
Where the money goes
Second-floor baths, slab foundations, and long drain runs are the big levers. Understand them before you finalize plans.
- How far fixtures move — across the room costs far more than a like-for-like swap.
- Whether drain lines need rerouting under a slab versus through accessible framing.
- Bringing old work up to current code — venting, shutoffs, and anti-scald valves.
- Fixture count and complexity — body sprays, pot fillers, and double vanities add rough-in work.
- Permit and inspection fees for the plumbing scope.
