- New space vs. conversion
- Building out the footprint adds foundation, framing and roofing; converting existing space avoids all three and is far cheaper per bathroom.
- Plumbing distance
- Tying into nearby supply and drain lines is cheap; running new lines across the house — or adding a stack — adds thousands.
- Fixture level
- A basic half bath is a fraction of a tiled full bath with a walk-in shower, glass and stone.
- Permits & inspection
- New plumbing and electrical trigger permits and inspections; venting and code compliance are non-negotiable line items.
