One word decides whether a sauna is an appliance or a building project: dedicated. It means the unit needs its own circuit run back to your panel — an electrician, a permit in most places, and a cost nobody puts in the product price. Of the 10 products whose electrical specifications we could read, 8 require one.
Most buyers read voltage as the tell. 240V means an electrician; 120V is the voltage of every socket in the house, so it sounds like something you unbox and plug in. That inference is wrong for 2 of the products here.
The Peak Saunas Everest is the clearest case. Its own product page states “Dedicated 120V, 20A Outlet” in the specification. Further down the same page sits a customer review saying it “runs on a standard 120V outlet, so there was no need for special electrical work.” Both sentences are on the page a buyer reads before spending $7,950. Only one of them is the specification.
We also found that same review text displayed on the Peak Denali and Patagonia pages, which are 240V products.
The Dynamic Saunas Barcelona lists “Electrical service: 120V/15amp” and never uses the word dedicated. But its heaters are rated 1.8 kW, and 1,800 W at 120 V is 15 A — the entire rating of a 15 A circuit, with nothing left over for anything else on it.
Whether that is acceptable on a shared circuit, and what the rules require for a load that runs for an hour at a time, is a question for a licensed electrician looking at your actual panel. We are not answering it. We are pointing out that the number the seller published and the number the heaters draw are the same number, and that this is worth raising before you order rather than after.

4 products in our set have no electrical specification on the product page at all — in some cases a running-cost figure in kWh, but no voltage, no amperage, no circuit requirement. That is a gap the buyer discovers after delivery.

Before you order anything here, get the answer to one question in writing: “Does this require a dedicated circuit, and at what voltage and amperage?” Then put that answer into our electrical checker to see what it means for your panel, and into the true-cost calculator before you compare it against anything else. A seller who will not answer in writing has told you something.
This is what sellers publish, not what your installation needs. We record the manufacturer’s stated requirement on the date shown. Your actual installation depends on your panel, your existing circuits, the run length and your local code — all of which require a licensed electrician. Nothing here is electrical advice and none of it substitutes for the installation manual or a qualified inspection.
Limits. 6 products in our database have no electrical record yet and are not counted in any figure above. Specifications change without notice. Where a seller states a requirement for a base configuration, heater upgrades can raise it — the Redwood cabin ships with a 6 kW heater and offers 8 kW and 9 kW options that do not carry the same requirement. “Not stated as dedicated” in the table above means exactly that: the seller did not say so. It is not our finding that a shared circuit is adequate.
