How much deposit can a bathroom remodel contractor ask for in Wisconsin?

Wisconsin law caps bathroom remodel deposits at 25% of the contract. On a typical $30,875 bathroom remodel, the maximum legal deposit is $7,719. The statute is Wisconsin Admin. Code ATCP 110. Any contractor demanding more is in violation of state law — refuse and report to the state contractor licensing board.

Industry standard for bathroom remodel: 15%. Mid-size job. Industry standard: 10–15% deposit covers fixture ordering. Resist any request above 25%. Most legitimate Wisconsin contractors will follow this norm regardless of whether the state has a statutory cap.

Yes — anything above 25% is illegal in Wisconsin under Wisconsin Admin. Code ATCP 110. File a complaint with the state contractor licensing board, share the written request, and consider it a permanent red flag against that contractor. Reputable contractors know the law.

Best practice in Wisconsin: 15% deposit at contract signing → milestone-based progress payments tied to inspectable phases (rough-in, mid-build, substantial completion) → 5–10% retention held until punchlist + final inspection sign-off. Never pay materials in full upfront; if your contractor goes under, the materials supplier owns those goods, not you. Pay via check or credit card — never wire transfer to a personal account.
