URSA Outdoor Sauna: 3 to 4 Person Garden Sauna

Delivery is available across the UK. Most mainland postcodes are included in the price; offshore and some remote postcodes carry an additional charge, and we confirm the figure for your address in writing before anything is dispatched.

The cabin arrives flat packed in one crate, 2.38m by 1.1m by 1.8m at 1,070kg plus the heater and stones, delivered by a lorry with its own rear mounted forklift that sets the crate down on a firm, level spot outside your property. The courier phones ahead to agree the day. From the kerb the panels move through the garden by hand, which is how a building of this weight reaches a spot no vehicle can. Once it has left the warehouse it is usually with you within three to eight working days.

Installation can be arranged where you would rather not build it yourself. Once you place your order we confirm the delivery and installation options for your location, and nothing is dispatched until you are happy with both.

Two years on the cabin from the date of delivery, under the manufacturer's published warranty. The heater, its controller and the lighting each carry their own maker's warranty, typically two to four years, and those terms are passed on to you in full with your order.

Thermally modified pine weathers to a soft grey under UV. That is the finish maturing rather than a fault, and no warranty anywhere covers the colour of timber standing outside.

Claims come to us. One email, and we deal with the manufacturer and the heater maker on your behalf rather than handing you a phone number.

This cabin is made to order in your choice of finish. Until the order is placed with the maker you can cancel and be refunded in full, with no reason needed.

After that, made to order goods are treated differently under the Consumer Contracts Regulations, and our returns policy sets out exactly where that leaves you. Check the crate on the day it arrives and tell us about any damage within 48 hours; anything that arrives damaged or faulty is ours to put right either way.

The URSA is the cabin in the middle of the range and the one most households end up with. Four people sit on two tiers along the back wall, the top bench 1.9 metres long and 625mm deep, and look out through a wall of darkened glass with a glass door in it. At 2,700 by 2,010mm it needs a real corner of the garden, and at 2,466mm tall it clears the 2.5 metre boundary cap by 34mm, which is close enough that the base decides the planning answer.

A wall of glass ought to be a heat problem, and in a thin walled cabin it is. The URSA gets away with it because the other three walls are 55mm cross laminated timber, layers of wood bonded crosswise so the panel stays stable and holds heat the way a solid log wall does. The floor is 60mm of the same, designed to balance moisture and resist mould. Outside is thermally modified pine, inside is knot free thermo aspen and alder, and a roof overhang on the side gives you somewhere to hang towels out of the rain.

Two heaters, and the decision is not how much heat you want. It is whether you would rather call an electrician once or sweep a flue twice a year. The electric option is the 10.5kW Huum Hive Mini with its glass fronted UKU WiFi controller and 150kg of stones; the stone mass is the point, because 150kg holds heat and gives soft, lasting steam rather than the sharp dry heat of a small heater working hard. It connects to 400V three phase at 3 × 16A, or to a dedicated single phase circuit of around 50 amps, and we confirm the right connection for your supply before you order. The wood option is the Huum Hive Flow Mini, supplied with a through the ceiling flue kit, protective bedding, a spill guard and stones. It needs no electrical supply at all, and the ritual starts earlier, with a fire.

Then one more choice: natural thermo pine, or the same cabin stained black. The black finish is a special order with a longer lead time, which we confirm before you commit. Everything else is already decided and already in the price.
