A full bathroom with shower/tub costs roughly twice what a half bath (toilet and sink only) costs due to additional plumbing, tile, and fixtures.
Adding a bathroom near existing plumbing (above or adjacent to a kitchen or other bathroom) significantly reduces pipe routing costs.
Tile floors in bathrooms cost more to install than vinyl or laminate but offer better water resistance and durability in wet areas.
Basic fixtures (toilet, vanity, tub) start around $500 total while mid-range sets run $1,500–$3,000 and high-end can exceed $5,000.
Building code requires exhaust ventilation in all bathrooms — adding a vent fan with ductwork to the exterior costs $200–$500.
Western states, especially California, have among the highest labor rates in the country. Strict energy codes add requirements but also incentivize efficiency upgrades that save money long-term.
Budget $300–$1200 for permits and inspections. Your contractor typically handles the permit process, but confirm this upfront.
Standard materials work well without extreme weather considerations. Focus budget on quality fixtures and efficient systems rather than climate-specific protections.

Yes — adding a full bathroom typically increases home value by $20,000–$40,000, with a return on investment of 50–60%. A half bath addition returns even more per dollar spent since it costs less. Homes with one bathroom benefit the most from adding a second.
