Cost of adding a bathroom — San Francisco, CA

Last updated: September 24, 2026

What affects the price

Remodeling costs vary based on your specific goals. Choosing high-end materials like natural stone or premium fixtures will shift your budget higher, while selecting standard options helps keep things affordable. The biggest price factor is the scope of work; a simple tub-to-shower conversion costs significantly less than a total gut renovation that moves plumbing lines or electrical outlets. Structural repairs found behind old walls can also influence the bottom line. We provide exact pricing confirmed free on the call.
