Can I move my toilet to the other side of the bathroom?

Usually yes, but the drain line and vent need rerouting — the cost depends on what is below (accessible crawl space versus concrete slab) and how far the vent must travel. A pro assesses it during the planning visit.

Do I need a permit for remodel plumbing?

In most jurisdictions, yes — any new, moved, or altered drain or supply work needs a permit and inspection. Like-for-like fixture swaps sometimes do not, but anything inside the wall almost always does.

Should I replace old pipes exposed during the remodel?

If demolition exposes galvanized, polybutylene, or corroded copper, replacing it while the walls are open is far cheaper than doing it later. Ask your plumber for an assessment while everything is visible.

How much does it cost to move plumbing in a Sacramento remodel?

Moving a fixture a few feet is a modest job; moving it across the room — especially drains through a slab or finished ceilings below — gets expensive fast. The honest answer comes from a pro looking at your specific layout, which is why the rough-in quote happens from plans, not guesses.

Should the plumber come before or after the general contractor?

The plumber IS one of the first trades in, right after demo — rough-in happens before insulation and drywall. But the plumber should see the plans before demo even starts, because layout changes are cheapest on paper.

Are remodel plumbing problems common in Sacramento?

New shower fixture installed during bathroom remodel

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.

Rough-in to trim-out — what's covered

The invisible work determines whether the visible work lasts. Expect the pro to cover both.

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.

Smart moves before rough-in

The cheapest plumbing change is the one made on paper. These planning steps save real money.

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

Remodel plumbing follows the construction sequence — and the plumber visits twice at minimum. Here is the order.

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.

The decision factors

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.

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.
