About

Full space for bathers, fire kept at a distance. Deluxe Tub External moves the wood burner outside the 180cm Thermowood tub, circulating heated water in rather than sharing internal space with a firebox. Easier to tend and refuel without reaching into the water. A safer distance for households with children using the tub alongside adults, with the full bathing volume kept clear for two or three.

Delivered flat-packed for self-assembly, with free UK mainland delivery on qualifying orders. The larger Cube format requires a little more assembly time than the smaller Icon models, so we recommend allowing a weekend and having a second person to help. A solid, level base and suitable delivery access are required. For a complete setup, select Professional Installation and choose your preferred date, allowing for the stated production lead time. We’ll then arrange the installation around your requirements, including any additional preparation or works needed to accommodate your sauna where possible.
Caring for this external burner wood fired hot tub means managing two separate elements: the tub itself and the external heater unit. After each session, let the firebox cool fully before clearing ash, and check the heater's connection point to the tub periodically for any signs of wear or leaking at the junction. Drain and refresh the bathing water regularly depending on usage frequency, and wipe down the full, uncompromised interior periodically, checking stave joints for leaks especially after the tub has sat empty for a period. Because the external burner sits outside the main structure, it's worth periodically checking its own mounting and stability, separate from the tub's general condition. Thermowood's natural weather resistance keeps exterior maintenance minimal for the tub itself. A light oil treatment every couple of years maintains the original colour if preferred, or allow natural weathering to a silvery grey, which requires no upkeep. Check the external heater for soot build-up periodically, since this affects heating efficiency regardless of its position relative to the tub.

Production takes 2-4 weeks, plus 1-2 weeks dispatch time for pallet haulage. This sauna is delivered flat packed unless otherwise stated. Free UK mainland shipping applies. If your order exceeds standard pallet limits due to length, weight, or quantity, additional pallet charges may apply and are quoted separately based on postcode.

Deliveries are kerbside and unloaded using the vehicle's tail lift, so no machinery or extra help is needed on your side. For properties with tight or restricted access, we can arrange delivery on a smaller vehicle with the goods handballed off instead — just let us know your access situation before ordering.

Please have a solid, level base and clear access ready before delivery. Pallet deliveries are kerbside only, and once unloaded you're responsible for moving the goods onto your property. Final positioning is not included unless you use our installation team. A comprehensive assembly manual is included, and self-assembly is straightforward with basic DIY skills.

Full bathing volume, fire kept outside

The Deluxe Tub External pairs the same 180 centimetre diameter and 93 centimetre depth as its internal burner sibling with an externally mounted stove instead, freeing up the full internal volume of the tub for bathers rather than sharing it with a firebox taking up valuable space. Heated water is circulated from the external burner into the tub, a configuration that keeps the inside of the tub completely clear and arguably more comfortable for the full two or three person capacity it is designed for.

Thermowood construction provides the same moisture resistant performance found across the range, suited to a tub that will be holding heated water outdoors continuously through every season the garden experiences. An external burner is generally easier to tend and refuel without needing to reach into the water itself, and it keeps the firebox at a safer distance from bathers, which some owners prefer over an internal arrangement, particularly where children might be using the tub alongside adults.

Deluxe Tub External suits anyone who wants the maximum usable internal space from their tub and does not mind the slightly larger overall footprint that comes with mounting the burner outside the main bathing area itself, a sensible trade for households who plan to use the tub regularly with more than one person at a time.
