Short answer
Bathroom costs move with tile labor, waterproofing, fixture level, plumbing relocation, ventilation, and whether you are adding a bath instead of remodeling one.
Cost drivers
What moves the number.
Waterproofing is not where to get cute
A cheap shower assembly can become the most expensive part of the remodel later.
Tiny rooms still need every trade
Demo, framing, plumbing, electrical, tile, glass, ventilation, and finish carpentry all show up.
Adding a bath changes the math
New plumbing runs, structural work, and permit review often matter more than square footage.
Planning ranges

| Added bath | $75k-$180k+ | New plumbing, framing, venting, and permit complexity. |
FAQ
Fast 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.
