What this is: a planning-range bathroom calculator informed by Kohler / Toto / Delta / Moen manufacturer pricing, HomeGuide, HomeAdvisor, Homewyse, and licensed cost-estimating references.
Size scaling: demo, paint, and floor-tile labor scale per square foot of bathroom area. Plumbing/electrical rough-in scale by layout type (powder/three-piece/master) and fixture relocation scope.
Labor is modeled from per-unit installed rates with a crew-rate sanity check ($75-$140/crew-hr loaded billing rate), informed by BLS OEWS 47-2152 (Plumbers / Pipefitters) and 47-2031 (Carpenters).
