Short answers to the questions that decide a sauna kit, each from the maker’s own documents or the store listing.
An indoor kit stands in a room you already have. Check the ceiling against the kit’s outside height: about 82 in for the Auroom Cala Glass, 86 in for the Kohler C1. Kohler also asks for a floor rated for at least 58.9 lb per sq ft under the C1.
An outdoor kit needs its own level, dry base, a roof that sheds the weather and power run out to it. Thermory prefers concrete, pavers or crushed stone under its barrels.

They run from one person in the Cala Glass Mini, about 38 by 37 in outside, to six in the Thermory No. 62 and No. 63 barrels, the Square No. 40 and No. 41 and the Kohler C2 6-person.
Footprints are outside length by width, with porches and roof overhangs where the maker includes them. Leave room around an outdoor kit to build it and to reach the door.

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.

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.

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 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 card opens the kit’s SaunaDesignPro page, where you can turn the model around and look inside. For a sauna of your own design, the designer builds it in 3D as you go.
