Bathroom Remodel Cost Boise: Guest vs Master Bath

Homeowners in Boise, Meridian, Eagle, Kuna, Star, Middleton, Nampa, and Caldwell ask us about bathroom remodel cost more than almost any other line item on a remodel budget. This article is part of our Boise Cabinet Cost Guide—the definitive hub for Treasure Valley remodeling costs.

Numbers below are planning ranges from design-build consultations, not advertisements. Your home, layout, and finish level will move you within or beyond these bands.

Use our project estimator for a rough range, then request an in-home visit for written scope.

Guest baths and powder rooms in Star, Middleton, and Kuna often land between $18,000 and $45,000 for a full refresh. Master suites with curbless showers, niches, and premium tile commonly reach $35,000–$85,000+.

Linear drains, large-format tile, and frameless glass increase labor. Waterproofing and flood testing are non-negotiable for inspectors in Ada and Canyon County.

Proper exhaust prevents mold in Idaho’s dry-but-steamy bath cycles. Radiant floor heat adds electrical load and thermostat zones—popular in Eagle and Boise Foothills master baths.

Relocating a toilet or expanding a footprint triggers plan review. Factor 2–6 weeks in Ada County depending on complexity.
