How much does the electrical installation of a sauna cost? The guide to the costs to expect

A premium outdoor sauna is not just a cabin to place in the garden: it is also a full electrical installation in its own right. At Ørigin, we make this step as simple as possible for you, but it is still useful to know exactly what it involves, both for the installation and for the electricity bill as the sessions add up. Here is everything to plan for.

Before you start

For reference only. The rates and procedures below are indicative (2026 tariffs, France). Every home is different: check with your electrician and your electricity supplier to confirm the exact cost before committing.

1. Is your electricity contract big enough?

In France, the power you subscribe to with your supplier is measured in kVA, usually between 6 and 12 kVA for a house. A sauna heater draws almost its full rated power during the warm-up phase: added to what your home is already using at the same time (water heater, induction hob, EV charger, electric heating…), it can trip your installation if your contract is too small.

Subscribed powerAnnual standing charge
6 kVA187,80 €
9 kVA234,72 €
12 kVA279,84 €

EDF regulated Tarif Bleu, Base option, indicative (2026).

Our advice: have your available power checked before the installation. Our advisors can estimate with you whether your current contract is enough or whether an upgrade is needed, and depending on the heater you choose, the required tier may differ.

2. How much does a power upgrade cost?

30 → 36 kVA517,20 €595,32 €+78,12 €/year

The Enedis fees for making the change

The fee for changing power is set by Enedis, the French grid operator, whichever supplier you use. It appears on your next bill, but is passed on in full to Enedis.

Type of meter / servicePrice incl. VAT
Linky smart meter: remote change4,28 €
Linky or standard meter + circuit breaker adjustment (up to 36 kVA)43,96 €
Power change + circuit breaker replacement65,45 €
Power change + switch from single-phase to three-phase184,84 €
Standard (non-smart) meter: technician visit required43,96 €
Linky smart electricity meter, green casing

Point to watch: depending on the heater you choose, a switch from single-phase to three-phase may be necessary (more often the case with a more powerful heater such as the Core 11 kW than with a Hive Mini 9 kW, depending on your home’s existing installation). In that case the cost of the change rises to 184,84 € instead of the 4,28 € of a simple remote change. An Ørigin advisor can help you anticipate this point before the quotation.

3. How much electricity does a sauna session cost?

The heater does not run at full power for the whole session: it heats hard at the start (warm-up), then cycles on and off to hold the temperature. Here is a realistic estimate for two of the most popular Huum heaters in the Ørigin range.

ModelWarm-upHoldingEnergy / sessionCost / session
Huum Hive Mini 9 kW30 min at full power30 min at ~50 %≈ 6,75 kWh≈ 1,35 €
Huum Core 11 kW40 min at full power40 min at ~50 %≈ 11 kWh≈ 2,20 €

Based on 0,2001 €/kWh (EDF Tarif Bleu, Base option, indicative). These figures vary with the cabin’s insulation, the outside temperature and the actual length of your session.

4. Examples of monthly cost by how often you use it

Sessions / weekHuum Hive Mini 9 kWHuum Core 11 kW
1×5,85 € / month9,53 € / month
2×11,70 € / month19,06 € / month
3×17,55 € / month28,60 € / month
5×29,25 € / month47,66 € / month

Even at 3 sessions a week, the budget stays close to a streaming subscription. The sauna remains one of the most economical wellbeing appliances to run day to day, especially compared with a spa or a hot tub.

6. Who does what? What the Ørigin package includes

Ørigin Saunas dedicated mini consumer unit with its circuit breakers and a service-request QR code

The electrical installation of a sauna involves up to three separate jobs. Here is how they are shared out:

Included in the Ørigin package

  • ✓Complete assembly of the sauna
  • ✓Connection of a second mini consumer unit, dedicated to the sauna
  • ✓Fitting the circuit breaker in that mini unit for the sauna and the appliances sold by Ørigin

Not included: your electrician’s responsibility

Adding the dedicated power, circuit breaker and cable in your existing main consumer unit, to feed the Ørigin mini unit. This work must be carried out by your own qualified electrician, and priced by them according to your installation.

Not included: to be priced in the quotation

Trenching or cable concealment, if there is some distance between the sauna’s location and your consumer unit. Ørigin can take care of it, but this item must be priced at quotation stage, case by case.

Not included: your electricity supplier’s responsibility

Upgrading your electricity contract, if its current power is not enough for the sauna (see sections 1 and 2).
