Short answers to the questions that decide a barrel, each from the maker’s own guide or the store listing.
A barrel is about as tall inside as it is wide, and only down the middle. The ceiling curves down toward the benches, so the inside diameter is the number to read.
Over six feet tall? Look at the 7 ft 3 in barrels: the Thermory 60 series and the SaunaLife EE6G. The Ergo is 6 ft 5 in across, the Thermory Cozy 6 ft 1 in, and the Finnmark stands 5 ft 11 in inside.
Sources: Thermory barrel brochure · SaunaLife EE6G listing · SaunaLife E6 dimensions · Finnmark FD-7 listingA porch gives you a dry spot for towels and shoes, out of the rain. Of the barrels here, only the Thermory line has one.
It comes out of the same 7 ft 4 in length. A 60 series room with the porch holds 212 cu ft; the same barrel without it holds 265 cu ft and seats six.
Sources: Thermory barrel brochure · Thermory 60 series listingA rear window lights the far end of the room. Thermory’s is a half-moon, 7 ft wide on the 60 series. SaunaLife’s Ergo W models add one too.
A glass front opens the door wall to the yard: the EE6G, the EE8G, the Ergo G models and the Finnmark. Want the back private? Choose a solid back, such as the Thermory No. 61 or 63 or the Ergo E6, E7 or E8.

Heater makers count glass as a cold surface, so a glass front adds to the room the heater sees. The EE6G’s 189 cu ft room is listed at 348 cu ft adjusted.
Each listing offers heater packages picked for that barrel: 8 kW for the EE6G, 8 to 10 kW or a wood stove for the EE8G. Thermory’s brochure puts it plainly: an electric heater needs a 240 volt line and an electrician.

Thermory prefers concrete, pavers or crushed stone, on a site free of standing water after rain. On grass, Finnmark puts pavers or flagstone under the cradles.
Level matters for the door: Thermory and SaunaLife both warn that an uneven base keeps it from closing right. The kit comes by freight truck with a liftgate, and the driver sets the crate down where the truck can reach. An EE6G crate weighs about 1,500 lb.

Thermory’s staves and cradles arrive cut to size. The one cut you make is the door opening in the front wall, with the hand saw in the kit. Book the electrician for the heater, and have the pad level before the crate comes.

Thermory prefers concrete, pavers or crushed stone, and its 2026 guide asks for the base frame to sit above the ground on a water-resistant layer such as bitumen strips. Finnmark also accepts wood decking, and on grass it puts pavers or flagstone under the cradles.

The SaunaLife EE8G listing offers a Harvia M3 or a HUUM HIVE wood stove with its chimney, floor plate and clearance kit, and the Ergo listing’s floor kit is the one to add with a wood stove. The Thermory listings offer electric packages.
