California rules that affect the cost
- Water-efficiency standards: new toilets must use no more than 1.28 gallons per flush, showerheads are limited to 1.8 gallons per minute, and bathroom faucets to 1.2 gallons per minute. Compliant fixtures are widely available, but check before buying online.
- Energy code (Title 24): new lighting generally must be high-efficacy LED, and bathrooms often need vacancy sensors or similar controls.
- Exhaust fans: bathrooms need mechanical ventilation, and many jurisdictions require humidity-controlled fans.
- Permits and inspections: most remodels that touch plumbing or electrical need a city or county permit.
- Older homes: remodels in older homes can uncover outdated wiring, galvanized pipes, or asbestos-containing materials that need professional handling.
Ways to save
- Keep the layout to avoid moving drains and supply lines.
- Get at least three bids, since prices vary widely between contractors.
- Shop for fixtures that already meet California standards to avoid returns.
- Consider a tub refinish or liner instead of full replacement.
