Sample insight
Mid-range full-gut bathroom remodels in Chicago typically run $26,000–$52,000 per bathroom in 2026, with suburbs and downstate IL commonly 10–25% below this range. Pre-1940 Chicago homes routinely absorb $3,000–$8,500 in unplanned cast-iron drain or galvanized supply remediation discovered after demo. (Estimate based on 2024–2025 Illinois permit and bid data.)
