About this buildout.
HUUM built the Flow so more of the heat from the wood goes into the room and less up the chimney; its maker's test data gives a gross efficiency of 74.9 percent. It holds 330 lb of stones and takes firewood up to 16 inches long.
The HIVE Flow is fed from the front inside the sauna. The HIVE Flow LS adds a firebox extension that passes through the wall, so the fire is fed from the next room. The LS is deeper, 29.5 inches against 24.8, and a little heavier.
The flue connects at the top or the back. The stove ships with a metal grate, an ash grate, an ash drawer, two cleaning hatches, two metal fixing plates, splints and a heat resistant glove. A buildout adds ten boxes of HUUM Stones 24, rounded olivine diabase of 2 to 4 inches.

“David, the owner, worked with us to get a high quality sauna. David is very responsive, knowledgeable, honest and responsive. He will have your sauna delivered to your home. He will then assemble the sauna and remove all the packaging. I highly recommend purchasing a sauna from Sauna Friend.”
Dennis DonovanFort Collins, CORead it on Google (opens in a new tab) “Sauna Friends were exceptional! They fixed my sauna door, added flashing, and reinstalled my sauna roof. I looked for sauna-specific professionals to do these repairs so I could be confident they'd know what they're doing, and they did.”
Jessmine AndersonColoradoRead it on Google (opens in a new tab) “Worthy of 10 stars! Went above and beyond to ensure we had full understanding in everything: the sauna we purchased, the ordering, delivery, and setup. Absolutely love our sauna and worth every penny. David was incredibly knowledgeable and went out of his way to over-deliver. Highly recommend working with David!”
