Short answer
The cheapest bathroom number is usually missing something. Waterproofing, tile labor, ventilation, permits, and plumbing changes deserve a real allowance.
Bay Area variables
What changes the budget here.
Tile labor is real money
Large format tile, niches, curbless showers, and custom details increase labor time fast.
Plumbing relocation changes the project
Moving drains, vents, and supply lines pushes the scope beyond finish replacement.
Added baths need permits
New bathrooms can require framing, plumbing, venting, electrical, structural, and city review.

FAQ
Bay Area answers.
Is this a contractor bid?
No. It is a planning estimate that helps you understand the likely budget range before drawings, engineering, city review, and contractor pricing.
Why is the range wide?
Early construction budgets should be ranges because site conditions, structural scope, utility work, finishes, permits, and contractor availability can move the number fast.
