Several local factors push Chicago bathroom remodel pricing above or below the national baseline:
Why is Chicago plumbing licensing stricter than other cities?
Chicago maintains its own plumbing license separate from the state of Illinois, and city code requires most plumbing work to be performed by a Chicago-licensed plumber. The Department of Buildings verifies the license on every plumbing permit.
Does Chicago follow the IRC?
Chicago uses the Chicago Construction Codes, which are based on the IBC/IRC 2021 cycle with extensive Chicago-specific amendments. The city historically diverged significantly from the model codes, and the current version is the closest alignment in decades.
Chicago Department of Buildings handles bathroom remodel permits in Chicago. Fees, inspection schedules, and code amendments vary by project scope.

You will be without this bathroom for the entire project — plan accordingly. See our Illinois permit guide for specifics.
Walk-in showers ($5,000-$10,000) are the most popular choice for primary bathrooms in 2026. Tub/shower combos ($2,500-$4,000) are better for families with small children. Keep at least one tub in the house for resale.
For cosmetic changes: no. For any plumbing modifications, electrical changes, or structural work: yes. Most mid-range and major bathroom remodels require permits.
Yes. Demo (removing old tile, vanity, toilet) is easy DIY that saves $500-$1,500. Painting is another easy save. Leave plumbing, electrical, tile setting, and waterproofing to professionals.
