What drives a bathroom remodel cost up or down?
Layout, surfaces, waterproofing and surprises all move the number. Layout: moving plumbing is real work, and one Scottsdale luxury renovation guide prices each relocation at $3,000 to $8,000 (2026). Size and surfaces: tile price per square foot and glass can take a large share of the budget. Waterproofing: a curbless shower and a walk-in shower are built differently under the surface, and that labor is invisible but not cheap. Surprises: an IBHS study cited by the Connecticut Insurance Department found that homes 30 years old were 3 times as likely to have a plumbing supply or drainage problem (Connecticut Insurance Department (opens in a new tab)), so older bathrooms sometimes reveal work that has to be fixed while the walls are open. Permits add their own line: one Phoenix-area remodeling firm puts a bathroom remodel permit at $150 to $400 in most Phoenix metro cities (2026).
