Remodel plumbing triggers

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 the pro does on a remodel

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.

Planning steps

Finalize the layout before the first pipe is cut — moving drains after rough-in is where budgets die. Do this first.

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.

How remodel plumbing works

From your floor plan to the first shower in the new bathroom — how it progresses.

  1. Plan review: the pro reviews your layout and flags what the plumbing will require — moves, venting, and code upgrades.

  2. Rough-in: new drain, supply, and vent lines are run and left ready for inspection before walls close.

  3. Inspection: the rough-in is pressure-tested and inspected per local code.

  4. Finish: after walls and tile, fixtures get set, connected, sealed, and tested.

Where the money goes

Moving fixtures costs far more than replacing them in place — distance is money. These factors set the budget.

  • 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.

Questions, answered

Twice, minimum: once for rough-in (after demolition, before drywall) and once for finish (after tile and walls are done, to set fixtures). Complex remodels may need a planning visit even earlier.
