Our pick

1. Harvia Variant View Corner

Corner indoor cabin, glass front

9.0/10

Harvia sells its Variant View in two corner versions, and the smaller is the one most homes will fit: 1,635mm square and 2,016mm tall, spruce inside and out, aspen benches and large glass walls on the front. Pool and Spa Centre's £5,581.72 includes a 6kW Harvia The Wall heater, and the Corner Large at 2,060mm by 2,033mm comes with 8kW for £6,688.79.

Oddly, the corner version costs £891.84 less than the straight Variant View Small, which is almost the same size. Harvia's product page doesn't show where the door sits, so ask Pool and Spa Centre for the plan drawing and check the door swing against your walls before you order. It ships as a package about 2.1m long, weighs 345kg packed and was on back order on 21 October.

Buy it if

  • A corner with about 1.7m clear each way
  • You want a Harvia heater in the price
  • You want glass on the front

Skip it if

  • Your corner is under 1.65m each way
  • You need it delivered soon

2. CenturaHeat 6-8 Person Indoor Corner Sauna

Hemlock corner cabin, electric

8.4/10

CenturaHeat's corner cabin is made to fill a corner: Pro-Line lists it at 2,000mm deep and 2,000mm tall with two 1,170mm faces, Canadian hemlock throughout and L-shaped seating for 6 to 8 adults. The 8kW stove comes with stones, and the whole cabin is £4,583.

It needs a 40A hard-wired supply. The control panel runs the lights and entertainment while the heater has its own control, and the extras include FM radio, Bluetooth speakers, LED belt lights and colour star lights. The warranty is 2 years on the timber and 1 year on the electrics, and the listing gives no wall thickness. At £573 to £764 a seat, it's the cheapest way here to seat six or more, if you have the people to fill it.

Buy it if

  • Six or more regular users
  • A free corner of about 2m by 2m
  • The most seats for under £5,000

Skip it if

  • Your consumer unit can't take 40A
  • You don't want a radio and lights in a sauna
  • Two or three people, where 8kW is wasted

Best built-in

3. Oceanic Domestic Sauna Kit

DIY kit: heater, glass door and fittings

8.2/10

A corner is the cheapest place to build a sauna from scratch, because the room supplies two of the four walls. Oceanic's £1,035 kit brings the heater with built-in controls, a 615mm by 1,895mm glass door with its frame, a heater guard, a vent kit, two spotlights and the accessories; you frame the two new walls, insulate and line all four, and fit the benches.

Built in, the sauna fits corners no standard cabin does, and you choose exactly where the door goes and which way it swings. The cost is the work: insulation, a taped foil vapour barrier and cladding on every wall and the ceiling, and an electrician for the heater. Oceanic ships door and kit orders in about 2 weeks.

Buy it if

  • Your corner is an awkward size
  • You can frame, insulate and clad
  • You want the door exactly where it suits

Skip it if

  • You rent, or may take the sauna with you
  • You want benches in the box
  • You'd rather not handle the vapour barrier

4. CenturaHeat 4-5 Person Infrared Diamond Corner Sauna

Infrared corner cabin

7.6/10

If gentler heat suits you, this CenturaHeat cabin puts 3,000W of carbon infrared panels into a diamond-shaped hemlock corner unit, 1,630mm deep and 1,900mm tall with faces of 1,010mm and 880mm. Pro-Line lists it for 4 to 5 people at £2,742.

It tops out at 65°C, so it isn't a Finnish sauna and there are no stones to pour water on. It still needs a 16A hard-wired supply, costs about 79p an hour at full power, and the price includes a radio, Bluetooth speakers and an ionizer you may not want. It's the cheapest corner cabin here and needs the smallest circuit.

Buy it if

  • You prefer lower temperatures
  • Your budget is under £3,000
  • A 16A circuit is easier than 32A or 40A

Skip it if

  • You want to pour water on hot stones
  • You want 80°C and above
  • You don't want a radio in your sauna

Using a dead corner for a sauna

A corner is often the one part of a room with nothing else to do, and a sauna there leaves the middle of the room free. There are two ways to use it: a freestanding corner cabin, which keeps its own four walls and needs a small gap from yours, or a built-in sauna that borrows the room's two walls and needs only two new ones.

Oceanic kit, built inYour cornerOceanic wall heater£1,035 plus timber

Freestanding cabins want air around them: Oceanic asks for a 25mm gap on every side of its cabins and Harvia's Fenix installation manual 5cm from the walls, so measure the corner from the skirting, not the plaster, and allow for any radiator. A built-in sauna avoids that gap, but the room's walls become sauna walls and need insulation and a foil vapour barrier, which the DIY sauna kits leave to you.

Five-sided layouts and L-shaped benches

A five-sided corner cabin cuts the front corner off at an angle, so the door sits on the diagonal and the benches run along the two back walls in an L. The L gives a long run of bench for the floor it takes, and the angled front stops the cabin pushing a square block out into the room. CenturaHeat's 6 to 8 person cabin, listed with two 1,170mm faces and L-shaped seating, fits this pattern.

A square corner cabin such as Harvia's 1,635mm Variant View Corner fills the corner fully and keeps a simple square plan. Its glass is on the front, so it suits a corner that faces into the room, and the door position is worth checking on the plan before it arrives.

Infrared cabins come in corner shapes too, running at 65°C or less, and the difference between infrared and traditional heat matters more than the shape. If lower heat appeals, the best infrared saunas include straight cabins as well as corner ones.

Door swing and getting the cabin in

Sauna doors open outwards: Oceanic asks for space for its cabin doors to swing out from a left or right hinge, and CenturaHeat specifies an outward-opening door on its compact cabins. In a corner that swing has to clear the side wall, any radiator and the door into the room. The doors here are about 600mm wide, 615mm on Oceanic's kit and 600mm on Harvia's Fenix, so keep a clear arc at least that deep in front of the cabin.

Measure the route as well as the corner: every doorway, stair turn and landing between the van and the room. If no corner in the house works, the best indoor saunas include straight cabins from 1.15m square.

Questions buyers ask

What is a corner sauna?

A corner sauna is a cabin shaped to stand in the corner of a room, either square against two walls or five-sided with an angled front and an L-shaped bench. A built-in corner sauna uses the room's own two walls instead of a cabin.

How much space does a corner sauna need?

From about 1.65m each way for Harvia's Variant View Corner to 2m each way for a 6 to 8 person cabin. Add the air gap the maker asks for and room for the door to swing out.

Which way should a sauna door open?

Outwards. Makers such as Oceanic and CenturaHeat specify an outward-opening door, so plan a clear arc in front of the cabin about as wide as the door, usually around 600mm.

Are corner saunas more expensive than straight ones?

Not always. Pool and Spa Centre sells Harvia's Variant View Corner at £5,581.72, which is £891.84 less than the straight Variant View Small at almost the same size.
