Kitchen and bath remodel plumbing

Remodel plumbing covers rough-in (moving or adding supply and drain lines before walls close) and finish work (setting fixtures). Moving a toilet or shower drain is the biggest variable, especially on a slab.

Layout review

Most remodel delays come from plumbing surprises: a drain that can't slope where the new layout needs it, a venting problem, or old pipe discovered when the wall opens.

The plumber works with you or your contractor from layout to final inspection — confirming what's possible before tile is ordered, pulling the permit, and setting fixtures at the end.

Kitchen & Bath Remodel Plumbing: common questions

Can you move a toilet or shower drain?

Usually yes. On a crawl space it's straightforward; on a slab the concrete must be cut and patched, which adds cost.

Do I need a permit for bathroom remodel plumbing?

Moving or adding fixtures, drains or supply lines typically requires a plumbing permit and inspection. Replacing a fixture in the same place usually doesn't.

What is plumbing rough-in?

Rough-in is the stage where new supply, drain and vent pipes are run inside open walls and floors, before drywall and tile. It's inspected before walls are closed; fixtures are set later in the finish stage.

Does remodel plumbing need a permit?

When piping is added, moved or replaced, yes, with a rough-in inspection before walls close and a final inspection after.

Should I replace old pipe during a remodel?

If it's galvanized, polybutylene or original to an older home, yes. Open walls make it the cheapest time.
