Wiring, permits, the pad.
How much does it cost to wire a sauna?
A dedicated 240 V circuit near the panel typically runs $250–$900. A detached outdoor sauna adds trenching and underground wire, about $600–$2,100; a full panel upgrade, if needed, is usually $1,300–$3,000 (a subpanel is often cheaper). Local labor rates move all of these.
Do you need a permit for a backyard sauna?
Usually for the wiring, often for the building. Many cities exempt small sheds (under 200 ft² in Minneapolis and Denver, 120 ft² in Seattle and New York City, 150 ft² in Chicago), but the 240 V circuit typically still needs an electrical permit. Pick your metro in the calculator for the published fees.
