Looking to make more of your garden? Steam & Oak offers products for creating a home wellness space, from outdoor saunas and wood-fired hot tubs to swim spas and heat pumps. The range includes compact designs for tighter spaces as well as larger options made for shared sessions.
Choosing the right setup is about more than appearance. You will need to think about available space, how you want to heat it, who will use it and what installation may involve. This guide explores the product types and examples listed in the supplied reference data, so you can compare the main features before deciding what to investigate further.
Steam & Oak’s listed range focuses on garden wellness and spa equipment. It includes outdoor sauna cabins and pods, electric and gas sauna heaters, wood-fired hot tubs, conventional hot tubs, swim spas and air source heat pumps. There are also sauna accessories, including a folding cedar bench and stone cages for compatible gas heaters.
Some listings are complete configurations with a heater, while others are cabin-only or shell-only options. That difference matters: a lower or higher listed price may reflect what is included, rather than a direct comparison between like-for-like products. Check the individual product details to understand the configuration.
The sauna selection spans several shapes and sizes. A compact cabin may suit a patio or a small garden, while a longer pod can make room for changing or cooling down as well as the heated area. Think of the layout as part of the session: a separate changing space can help keep the hot room from losing heat when people come and go.
The Ruutu 200 is described as a compact cube sauna with a footprint of 200 by 210 centimetres. It is built from 44mm thermowood, includes benches, seats four comfortably and arrives fully assembled. A tempered glass door is standard; a panoramic front is an optional configuration, with lightly tinted glass panels either side of the door.
Other compact examples come from Holl’s range. The Cocoon is a two-person outdoor steam sauna with a 130 by 130 centimetre footprint. The listing describes a heat-treated Canadian pine body, a tinted glass door, a rear window and a 4.5kW electric heater. The Hestia is a larger cube option, listed for three to four people, with double-height benches and a 6kW heater.
These examples show why it helps to measure the intended site before choosing a model. Allow for the cabin itself, access around it and any installation needs. A small footprint can be appealing, but the product still needs a suitable base and appropriate power arrangements where relevant.
The Kaari 195 is an oval pod designed to fit a two-room layout into a width of 1.95 metres. Its listing describes a heated room and a separate changing area, with a total length of 4.06 metres. Configurations include a 6kW or 8kW Harvia electric heater, as well as a cabin-only option.
For a different use of space, the Kaari 240 Terrace combines an enclosed hot room with a covered open terrace. The terrace sits under the same roof, providing a place to cool down between rounds without adding a separate structure. Listings show different heater configurations, including electric, gas and wood-fired options, as well as cabin-only versions.
The Kaari 300 extends the idea with a larger oval layout, a covered terrace and a changing room. The supplied product descriptions list several configurations, including gas and electric heater options. Compare each listing carefully: heater type, safety pack and included equipment can vary.
A sauna’s heater affects how it operates, what services it needs and the kind of experience it offers. The supplied listings include electric, wood-fired and gas options. There is no single best choice for every garden; the right one depends on your site, preferences and the product’s installation requirements.
Electric configurations are available on products such as the Ruutu 200 and Kaari pods. The listing for the Cocoon, for example, specifies a 4.5kW electric heater, while the Hestia listing specifies a 6kW unit. Electrical work should be checked against the precise product information and handled by a qualified professional where required.
Gas options appear in the Kaari Terrace and Kaari 300 listings, including configurations using FinSteam Botnia or Aurora heaters. A separate Botnia 81 heater listing describes an off-grid propane unit and notes requirements such as a propane bottle, regulator and installation specifications. Gas does not mean installation is automatically simple: check clearances, ventilation and the manufacturer’s directions.
Wood-fired heaters offer another route, and some Kaari configurations are listed with a Harvia M Series heater. They may appeal if you want a fire-led routine, but consider fuel handling and the practical needs of the site. As with any heater, read the product-specific guidance before making a decision.
Steam & Oak’s listed hot tubs include several wood-fired models and Platinum spas. Their formats differ, so start with the number of people you expect to use the tub and the space available. Then compare capacity, heater placement and the work involved in getting the water ready.
The Hehku range includes round and squared designs. The Hehku 800 is an oval 800-litre tub for two to three people, with an external wood stove. The Hehku 1150 is listed at 1,150 litres for four to five people, with an integrated stove. The larger Hehku 1650 XL is described as a 1,650-litre tub for six to seven people, also with an integrated stove.
Stove position changes the layout. An external stove sits outside the tub, while an integrated stove is built into the tub wall. The listings describe wood-fired models as operating without a pump, control panel or electricity for heating. They also make clear that heating time can be a trade-off: the larger tubs may take longer to heat from cold than smaller ones.
Before choosing a wood-fired model, consider how you will manage the fire and plan each session. If you prefer a tub that is ready on demand, compare the available spa and heat-pump options instead. Neither approach is automatically better; it is a question of which routine fits your household.
The Platinum 13 is listed as a five-person hot tub with two loungers and three additional seats. Its description includes 42 stainless-steel jets. The Platinum 14 is a seven-person model with 56 stainless-steel jets, according to its listing. Both are presented as social spa options, but the seating layout and footprint should be checked against your available space.
For people who want room for swimming-style exercise as well as relaxation, the Platinum Swim Elite is a single-zone swim spa with a Vortex 5kW swimming system and hydrotherapy seating. It combines a continuous swimming current with a separate seating area in one body of water. Compare the dimensions and site needs with those of a standard hot tub before deciding whether the extra swim space is useful to you.
Air source heat pumps are listed as accessories for hot tubs and swim spas. They transfer heat from outdoor air into the spa water, rather than generating heat directly in the same way as a standard element heater. The reference data includes products from iNHEAT SpaLine, Gecko, Inverboost and AQUARK, with different outputs and features.
Some listings describe inverter operation, which adjusts output to match heating demand. Product options also vary by model, output, operating conditions and controls. For example, the iNHEAT SpaLine listing describes heating and cooling, Wi-Fi control and operation down to -25°C. Other listings describe different operating ranges or optional Wi-Fi. These are product-specific details, so do not assume one model’s features apply to the whole range.
Check compatibility with your spa before buying. The supplied heat-pump listings note that installation is not included unless clearly stated, and that electrical connections, pipework and commissioning should be completed by a qualified professional. They also advise allowing suitable clearance, airflow and access for servicing.
Several outdoor sauna listings feature thermowood. The product descriptions explain that it is heat-treated timber, not timber treated with a chemical surface coating. Examples include the Ruutu 200, Kaari pods and Vanne barrel sauna. Other listed products use heat-treated Canadian pine, while some indoor sauna models use Canadian spruce or hemlock.
Look beyond the material name. Check wall thickness, glazing, bench layout, roof design and the dimensions of the complete product. For example, the Ruutu 200 has a rounded roof-to-wall form, while the Kaari models use oval shells and may add a changing area or terrace. These details can affect how the sauna fits your garden and how you move through a session.
Installation requirements vary by product. Some listings mention a firm, level base, assembly by two people or a dedicated outdoor-rated electrical supply. Others call for work by a qualified electrician or suitably qualified installer. Make sure the site is ready and the required services are available before placing an order.
The supplied listings include prices for individual products and configurations, but they do not provide a consistent comparison of every option. Prices can differ because one listing may include a heater while another is for a cabin or shell only. Some products also have multiple heater, finish or safety-pack choices.
For a useful comparison, match the details first: product size, stated capacity, heater type, included accessories and installation needs. Then check the current product page for the exact configuration and price. The reference data does not provide a general discount, so avoid assuming that a listed price represents a sale or that another configuration costs the same.
ZoneOffer is a comparison site, not the store itself. Its role is to help shoppers review offers and product information from retailers. If you use ZoneOffer to explore Steam & Oak products, confirm the latest details on the retailer’s product page before making a purchase.
Shipping information is not provided for the Steam & Oak range as a whole in the reference data. Some individual heat-pump listings mention free standard delivery, but that detail should not be treated as a store-wide policy. Check the relevant product page for delivery arrangements, installation, lead times and any site-access conditions.
Steam & Oak’s range may suit shoppers who want to compare several types of outdoor wellness equipment in one place. A small cabin, a two-room pod, a wood-fired tub and a swim spa solve different needs, so begin with the experience you want rather than the product name. Do you picture quiet sauna sessions, a shared soak, or regular swim training?
Next, measure your site and compare the practical requirements. Think about the number of regular users, the available power or fuel, the base, access for delivery and the time you are willing to spend preparing the equipment. A little planning now can help you avoid choosing a product that looks right online but does not suit your space.
Steam & Oak’s listed selection covers everything from compact outdoor saunas to larger pods, wood-fired hot tubs, Platinum spas and heat pumps. The best choice depends on your space, preferred heating method and how you plan to use it. Compare like-for-like configurations, check installation requirements and confirm current price and delivery details on the relevant product page before you buy.
