Planning the Layout

Keep the new bathroom as close to existing plumbing as possible to minimize pipe runs and cost. Back-to-back bathrooms sharing a wet wall is the most economical layout.

Code Considerations

Every fixture needs a properly sized trap and vent. The toilet requires a 3-inch drain minimum. Supply lines must have accessible shut-off valves.
