Product Description
A sauna and a hot tub in one Hobbiton building
The TimberIN Nordic Hobbiton™ Combo combines a rounded, Hobbit-style Thermowood sauna and an open hot tub with a 1,800 mm inner diameter in one factory-assembled building of about 4,600 × 2,400 mm. The sauna cabin seats 2–4 people and the hot tub 4–6. Choose the hot tub heating (integrated wood-fired stove, electric or hybrid) and, separately, the sauna heater: a Harvia 20 SL wood-burning stove or a Harvia Cilindro PC90 electric heater. Compare it with our other sauna and hot tub combinations.
The building and the delivery are shared, but the two zones keep their own heating. The electrical, water and maintenance requirements are planned for the complete unit.

Choose the heating
Choose the hot tub heating and the sauna heater independently: a wood-fired sauna heater is a Harvia 20 SL, an electric one a Harvia Cilindro PC90. The wood-fired and the electric hot tub cost the same; the electric sauna heater costs £880 less than the wood-fired one.
| Hot tub heating | Sauna heater | Price |
|---|---|---|
| Integrated AISI 316 wood-fired stove | Wood-fired: Harvia 20 SL with chimney | £14,990 |
| Integrated AISI 316 wood-fired stove | Electric: Harvia Cilindro PC90 9 kW | £14,110 |
| Electric heater 6 kW (WiFi-ready – WiFi module available as an add-on) | Wood-fired: Harvia 20 SL with chimney | £14,990 |
| Electric heater 6 kW (WiFi-ready – WiFi module available as an add-on) | Electric: Harvia Cilindro PC90 9 kW | £14,110 |
| Hybrid: Electric heater 6 kW (WiFi-ready – WiFi module available as an add-on) + integrated wood-fired stove | Wood-fired: Harvia 20 SL with chimney | £15,680 |
| Hybrid: Electric heater 6 kW (WiFi-ready – WiFi module available as an add-on) + integrated wood-fired stove | Electric: Harvia Cilindro PC90 9 kW | £14,800 |
Wood-fired hot tub
The hot tub has an integrated AISI 316 stove that you load from outside. Follow the exact manuals, the approved plan and the site requirements for protection, flue installation and clearances.
Electric or hybrid hot tub
The electric version has a 6 kW electric heater (WiFi-ready – WiFi module available as an add-on); the hybrid adds it to the integrated wood-fired stove. A more powerful tub heater (9, 12 or 15 kW, three-phase) is available as an option.
Sauna heater
Wood-fired: a Harvia 20 SL, nominally 24.1 kW, with chimney and wood loading from outside. Electric: a Harvia Cilindro PC90 9 kW. Give the full equipment specification to a qualified electrician before the supply is designed.
Options
Hydro massage (£690); smart kits (Wi-Fi) for the air massage (£160), the sand filter (£160) and, with an electric heater, the electric heater (£190); the electric connection type and a more powerful electric heater (9 kW £190, 12 kW £290, 15 kW £390); and a braked two-axle road trailer (£4,450). Shipping takes one choice; hydro massage, Smart SPA and the trailer take several or “None”; the electric connection appears only with an electric heater.
The wood-fired version also needs electricity
The LED lighting, air massage, sand filter and UV filter need suitable outdoor electrical supplies even when both zones are heated with wood. The circuits require appropriate protection and earthing for the supplied equipment.
Plan the complete electric installation
With an electric tub heater and an electric sauna heater there are two heaters with separate requirements, plus the auxiliary equipment. The 6 kW tub heater runs on 220 V single-phase (26 A) or 380 V three-phase (14 A); the Harvia Cilindro PC90 is listed for 400 V three-phase (3 × 16 A) or 230 V single-phase (1 × 40 A). Air massage needs 220 V 4 A, hydro massage 220 V 5 A and the sand filter 220 V 2 A.
A qualified electrician must determine the cables, earthing, protection and isolation for the UK site from the equipment plates, the exact manuals and the total installed load.
Included filtration, UV and air massage
Every version includes the sand and UV filters, air massage and tub LEDs. Allow an accessible technical area and the required electrical connections, so that the equipment can be inspected and maintained without moving the building.
Use the exact component manuals for water treatment, filter operation, cleaning, winterisation and maintenance intervals. No generic schedule replaces the supplied instructions.
Prepare the base, access and services
The base must be level and designed for the full operating load: the unit, a full hot tub, people and equipment. A foundation designed for a hot tub alone must not be assumed suitable for the combined building.
Plan water filling and drainage, heater clearances, filtration access and service positions from the approved drawing. Confirm ground capacity, gates, turns, overhead restrictions and truck manoeuvring space before production.
Factory-assembled delivery
The Hobbiton Combo is delivered factory assembled; it is not offered as a flat-pack. Delivery is quoted separately from the postcode and requires unloading machinery (crane or forklift) on site. The customer arranges unloading from the truck and movement to the final base.
If suitable machinery is unavailable, delivery to a local provider with a crane truck can be discussed. That provider may separately quote the final journey, unloading and placement. Such an arrangement must be agreed and priced beforehand; it is not automatically included.
Why choose the Nordic Hobbiton Combo?
This model suits a project that wants a 1.8 m hot tub and a sauna for 2–4 people in one rounded Thermowood building, with three hot tub heatings, a wood-fired or electric sauna heater and factory-assembled delivery. Separate products give more freedom in positioning; for a two-room sauna without a hot tub, see the Nordic Hobbiton™ Glass, or compare all sauna and hot tub combos.
