Short answers to what decides an outdoor kit, each from the maker’s own documents or the store listing.
Kits come by freight. The CL5G arrives curbside on a liftgate truck, and the Kohler C2 comes in one or two large pallets whose sections carry through doorways. Plan the route from the curb to the site.
Outdoors, the base comes first: Thermory prefers concrete, pavers or crushed stone that stay dry, kept level so the door closes right.

Each listing names its kit’s roof and what comes with it.

Kohler’s C2 plugs into a NEMA 14-50 receptacle on a 50 A circuit with a Class A GFCI, and Thermory’s brochure puts it plainly: an electric heater needs a 240 V line and an electrician.
A wood stove needs no heater circuit, but it needs a chimney and the clearances its manual sets. The SaunaLife G2 offers one.

Auroom puts the Cala Glass at about 4 to 6 hours for two people. Thermory’s guides call for two people on every barrel, and SaunaLife rates the G2 at two days for two.
Kohler recommends a professional installer for the C2, and the Kohler C1 and C2 listings offer white-glove delivery and assembly as an option.

Glass also takes heat out, so heater makers count it as extra room: Harvia adds 3.94 cu ft for every square foot of glass, HUUM 3.3. The heater catalog adds it for you.

The others offer heater packages chosen for that sauna on the listing: a Harvia KIP, Spirit or HUUM DROP for the CL5G, a Harvia KIP or Saunum Air Perfect for the Cala Glass.
For wood heat, the SaunaLife G2 listing offers a Harvia M3 or HUUM HIVE Flow stove. Size any heater on the room plus the maker’s allowance for glass; the heater catalog does the sum.

Thermory prefers concrete, pavers or crushed stone under its barrels, and asks for the base frame to sit above the ground. Each kit’s manual gives its own base.
