Saunum Air 7 Sauna Heater Package Air Series, 7kW Sauna Heater Package Model AIR 7 CSB PKG
The Saunum Air 7 CSB Package is the complete, ready-to-install 7kW Saunum Air package in black steel with a closed stone basket - the Air 7 CSB heater, AirIQ WiFi control, 110 lbs of sauna stones, and Himalayan salt spheres, all in one purchase. It covers the same room range as the Air 7 SSB Package (177 to 318 cubic feet) and uses the same 40A / 8 AWG electrical installation, but differs in two ways: the finish is black steel rather than polished stainless, and the stone basket is closed rather than open. The closed stone basket (CSB) encloses the stones within the heater body rather than presenting them in an open visible basket - a design difference that affects both the visual character of the heater in the room and the character of the loyly steam it produces. The AirIQ WiFi control, Himalayan salt spheres, and all six sauna bathing styles are identical between the CSB and SSB packages.
CSB vs SSB - closed basket vs open basket
The two Air 7 packages available at this output level differ in basket design and finish. The SSB (open stone basket, stainless steel) presents the stones in a visible open basket and carries 130 lbs of stones - the larger stone load that the open basket format accommodates. The CSB (closed stone basket, black steel) encloses the stones within the heater body and carries 110 lbs. In an open basket heater the stones are visible and the heat radiates from all exposed stone surfaces simultaneously; in a closed basket heater the heat concentrates and builds within the enclosed stone chamber before being released, producing a different quality of loyly steam - often described as more concentrated and sharp when it arrives. Neither is objectively better; the preference is personal and relates to the sauna experience the bather is seeking. The closed basket also produces a cleaner, more contained visual profile in the sauna room - a compact black unit rather than an open stone column.
Black steel - the compact enclosed Saunum Air
The CSB package is finished in black steel with a compact, enclosed exterior. Where the SSB open basket in stainless reads as a stone feature in the sauna room, the CSB reads as a contained black appliance that recedes visually into dark cedar or contemporary sauna interiors. The black steel finish suits dark material palettes - dark cedar, charcoal tile, black hardware, and thermally modified wood - where the enclosed heater integrates into the room rather than standing as a visual centrepiece. All Saunum Air technology is unchanged: the patented climate equalizer fan runs identically in both basket formats, the Himalayan salt reservoir sits within the airstream in the same position, and the AirIQ WiFi control operates both models in exactly the same way.
Complete package - AirIQ WiFi, 110 lbs stones, and salt spheres included
The Air 7 CSB Package is complete: the heater, AirIQ WiFi control, 110 lbs of sauna stones (4 boxes), and Himalayan salt spheres arrive together with no separate sourcing required. The AirIQ control enables all six sauna bathing styles, remote preheat via the Saunum app, and up to 3 saved preset configurations. The 110-lb stone load is the correct specification for the black closed basket Air 7 model. Electrician required for the 240V/1-phase wall connection: 40A breaker, 8 AWG wire.

Why the Saunum Air 7 CSB Package stands out
Closed basket - concentrated steam, compact profile
The enclosed stone chamber concentrates heat within the basket before release, producing a different loyly quality than the open basket SSB - often more focused and sharp when it arrives. The closed exterior creates a compact, contained black profile in the sauna room rather than a visible stone mass, suiting sauna designs where the heater should integrate quietly into the space.
Complete package - nothing else needed
Heater, AirIQ WiFi control, 110 lbs stones, and Himalayan salt spheres included. No separate control purchase, no stone order. Everything for a fully operational 7kW Saunum Air installation arrives together. Only the electrical connection by a licensed electrician remains.
Same patented air mixing as SSB
The climate equalizer fan operates identically in both basket formats. The patented air mixing system draws ceiling air, blends with floor air, and distributes the mixed airstream throughout the room - reducing floor-to-ceiling temperature variance by more than 60%. The basket design affects steam character, not the air mixing performance.
Black steel - suits dark and contemporary interiors
The black steel finish integrates into dark cedar, charcoal tile, black-framed glass, and thermally modified wood sauna interiors. Where the stainless SSB model stands as a reflective metallic element, the black CSB recedes into darker palettes as a contained, utilitarian form.
AirIQ WiFi - 6 bathing styles, remote preheat
Included AirIQ WiFi control with full Saunum app connectivity - same as the SSB package. Russian Banya, Finnish, Estonian, Yoga, Salt, and Aroma sauna styles. Preheat remotely before arriving. Save up to 3 preset configurations for one-tap starts.
40A / 8 AWG - same as Air 7 SSB
Identical electrical requirement to the Air 7 SSB Package: 240V/1-phase, 40A two-pole breaker, 8 AWG wire. The basket design choice does not change the electrical installation. Standard 2-pole only - no GFI/GFCI. A licensed electrician is required for all connections.

CSB vs SSB - the basket choice
Air 7 CSB Package vs Air 7 SSB Package - basket and finish are the only differences
Both packages cover 177-318 cu ft, require 40A / 8 AWG, include the AirIQ WiFi control and Himalayan salt spheres, and deliver all six Saunum sauna bathing styles. The differences are basket type, finish, and stone capacity. CSB: closed basket, black steel, 110 lbs stones - compact black profile, concentrated enclosed steam character. SSB: open basket, polished stainless steel, 130 lbs stones - visible stone mass, open radiating steam from all stone surfaces. Both are valid and complete choices; the decision is based on sauna interior design and steam experience preference.
A standard 2-pole 40A breaker and 8 AWG wire are required for both. Do not connect to a GFI or GFCI breaker. A licensed electrician is required for all connections.
