Outdoor Cube Saunas

Are cube saunas good?

A cube sauna is an outdoor sauna with straight walls and a flat floor on a square or rectangular footprint, so the room inside is box-shaped with upright walls behind the benches. A barrel sauna gives up some shoulder room under its round walls, and a pod curves its walls up into an arched roof. Barrel and square saunas compared weighs the two shapes for a backyard.

Outdoor cube sauna sizes compared

Outdoor cube saunas by household:

• Two or three people: the SaunaLife CL3G, the smallest of the six, or the CL4G for a third seat.
• Four people: the SaunaLife CL5G for a full-height glass front, or the Dundalk Luna for cedar with freight included within the contiguous United States.
• Six to eight people: the SaunaLife CL7G seats six, the CL12GCP eight plus a dressing room and porch.

SaunaLife cube sauna materials

SaunaLife builds the walls of its Cube Series saunas from full-length Thermo-Spruce wall staves, spruce that has been thermally modified, which SaunaLife describes as stronger and more dimensionally stable and naturally resistant to decay and pests. The benches and backrests are Thermo-Aspen, which SaunaLife says gives a cool-to-the-touch seating surface, and the glass is 0.31-inch (8 mm) tempered bronze glass under a shingled roof.

Heater packages for outdoor cube saunas

Each outdoor cube sauna's product page offers electric heater packages sized for that model, with one marked Recommended: a HUUM DROP on the three smaller SaunaLife cubes, a 6 kW DROP on the Dundalk Luna, the size Dundalk LeisureCraft recommends, and a Saunum Air L on the CL7G and CL12GCP. Harvia KIP packages are also offered on the four smaller cubes, HUUM HIVE Mini or Harvia Cilindro packages on the two largest. No wood-burning package is offered for any cube; the saunas that take a wood stove are in outdoor wood fired saunas. Each electric heater needs its own dedicated circuit, and your licensed electrician sizes the breaker and wire from the manual that ships with the heater and your local code.

Outdoor cube sauna delivery and assembly

SaunaLife ships each of its cubes as a kit on a wooden pallet, at SaunaLife's own freight charge whatever the order value; the CL12GCP comes on a flatbed truck and needs a forklift or crane to unload. The Dundalk Luna ships as a kit in a 1,526-pound crate; the carrier does not unload the crate, so plan the offload before delivery, and Dundalk LeisureCraft's assembly instructions recommend two people. Each cube travels by freight to a curbside delivery booked by appointment and is assembled on site on a level foundation, so raise site-access questions before you order.

Topture is an authorized SaunaLife dealer, listed in SaunaLife's dealer directory, and an authorized Dundalk LeisureCraft retailer; each cube ships under Topture's full-value freight protection, and buying any backyard sauna from Topture is covered on the outdoor saunas page.
