HEKLA SAUNAS · POSH SPAS GUIDE

How to choose the right home sauna.

Start with location and heat type. Once those two choices are clear, the correct size, heater and installation requirements become much easier to decide.

1. Indoor or outdoor?

An indoor sauna suits a spare room, large bathroom, garage, basement or wellness room. It avoids garden groundwork and keeps the sauna close to the rest of the home. HEKLA’s indoor range includes both full-spectrum infrared and traditional stove-heated cabins.

Outdoor saunas create a separate destination in the garden. HEKLA Cube, Barrel and Cabin models are designed for this environment, but they need a suitable permanent base, delivery access and advance planning for heating/electrics.

2. Infrared or traditional?

Infrared Traditional
Typical temperature 45–60°C 70–90°C
Warm-up About 10–15 min About 30–45 min
Heat Direct radiant warmth Heated air + stones
Steam/löyly No Yes
Electrical 13A plug on current HEKLA infrared models Dedicated circuit for electric heater

3. Choose the heater

Harvia The Wall

A slim wall-mounted heater used for indoor traditional cabins and selected cabin configurations. The HEKLA range uses 6–9 kW outputs depending on the room.

Harvia Cilindro

A floor-standing column heater for outdoor models. Its large stone surface creates an even, enveloping traditional heat. Current HEKLA options include 6.8 and 9 kW.

Harvia Linear 18

A 14.3 kW wood-burning alternative for compatible outdoor Cube and Barrel models. It trades one-touch convenience for the fire, aroma and tending ritual of wood heat.

4. Pick the right size

Choose for how the sauna will usually be used. A couple who occasionally has friends over may still be happier with a smaller, faster-heating sauna than a large cabin used half-empty most of the time. Think about whether lying down on a bench matters to you as much as stated seating capacity.

5. Plan the controls

Digital and Wi-Fi controls are worth considering if you want scheduled heating or remote start. Compatible HEKLA/Harvia setups can use the Fenix touchscreen and MyHarvia app for temperature control, scheduling and monitoring.

6. Prepare the site

Outdoor saunas require a flat, solid permanent base. Concrete is ideal; correctly prepared reinforced paving can also work. Grass, loose gravel and soft ground are unsuitable. Allow a clear delivery route and working space around the footprint.

Posh Spas tip: talk to us before arranging electrical or groundwork. We can confirm the chosen model’s footprint, heater and access requirements first.
