The S1 by Klafs: Sauna with Zoom


No rule is irrefutable – if you're willing to be bold and throw everything you've ever seen so far overboard. When it came to saunas there was always one drawback: anyone who's ever dreamed of having their own private sauna, needs sufficient space for it. And that space can then no longer be used for other purposes once the sauna is installed. 


In our times of increasingly scarce living space, this drawback quickly becomes an obstacle and causes many sauna enthusiasts to put their dreams of having a sauna on a back burner or even to just shelve the idea altogether. The designers at Klafs did not let this challenge go unresolved - and began a whole new, radically different sauna design. 


The designers' vision: the really ingenious solution to this challenge was a sauna, which is very small when not being used – and really large if you want to relax in your own sauna. It is also designed as a completely self-contained, mobile system and can be moved just like a closet if you move out. 


After about three years of intensive development work and a whole range of technological developments, the result of this completely new approach is ready for the market: the new S1 from Klafs.  

In its fully retracted state the S1 is a mere 60 centimeters deep, just like the average closet. 

By pressing a button on the front panel controls, the Klafs S1 extends in just 20 seconds into a ready-to-use sauna which is nearly three times as deep. 

The S1 has a sophisticated, multi-level security concept The sensor automatically stops the cabin from extending or retracting if something gets in the way. The cabin can only be retracted once the heater has cooled down and the heater can only be started once the cabin has been fully extended. Important for parents: the controls can be secured with a password. 

The S1 consists of three elements which fit into each other completely. And thanks to the patentpending eMove technology, almost silently and synchronously. 

The key highlight of this sauna is its minimal space requirements. In its fully retracted position, the S1 is only 60 centimeters deep, just like the average closet. Yet the S1 is a really stylish designed sauna down to the last detail and with room for the whole family. By pressing a button on the new, extremely compact and slim controls on the front panel, the S1 extends into a ready-to-use sauna in just 20 seconds and is nearly three times as deep. That's because it consists of three elements which can be completely fitted into each other. And all that virtually silently and synchronously, thanks to the patent-pending eMove technology.  


So the new S1 is moving, in the true sense of the word, as well as different. And the basic idea of a flexible construction has also kept the design team at Klafs moving. However, all the meticulous development work was certainly worth it. Because now, for example, after undergoing rigorous endurance testing, eMove technology stands out with details, such as durable guides with self-lubricating components, high-quality industrial ball bearings, an automatic shut-off on contact with an obstacle, as well as flexible connection technology between the individual elements. This flexibility also ensures that the S1 easily overcomes any small floor irregularities and can therefore put a wide variety of floor coverings to the test with its skills. 


But the designers at Klafs also had to overcome some technical obstacles for the S1. The completely new design of the cabin with three interlocking moving elements would have been unthinkable with the usually used wall construction. So, in a project supported by the Federal Ministry of Economics with the scientists at the Institute of Wood Technology (IHD) in Dresden, KLAFS developed the frame stability construction for the S1 - an extremely robust wooden sandwich wall construction, which is 40 percent lighter than the one used in a conventional sauna. In addition, the amount of valuable wood used is reduced by about two thirds compared to the previous design. 


The S1 is available in three sizes (small, medium and large), with five different exterior trims (white, white satin, Swiss pine, walnut and oak) and four different front panels (fully glazed with clear safety glass, fully glazed with bronze safety glass or fully glazed with mirrored safety glass, closed with a side window). For the interior trims we offer naturally grown, knot-free eastern hemlock or waxed walnut wood as well as the wood of the lively patterned Swiss pine on request. The side panels, front and ceiling are all equipped with the same surfaces and are available on request with side windows. This gives the sauna S1 an all-round harmonious appearance - no matter what combination customers choose.  


Even the heater, the heart of every sauna, had to be completely redesigned for this flexible construction. The new, compact yet powerful Varius heater features an elegant flock finish on the outer shell, which makes the usual safety guard unnecessary. Thanks to its Drive Home System, the heater automatically moves out of its “garage” under the bench when the sauna is opening. All the connection technology of the heater is out of sight, housed in the multi-function channel.  


The innovative control concept of the S1 is available in two models: ML 028 with a color display and five soft keys or ML 033 with color touch screen, intuitive menu navigation and optional Wi-Fi interface for controlling the sauna remotely with the sauna app.  


Another technical highlight is closely linked to the heater but stays visually very discreetly in the background: the optional exhaust air module SCC (Safe Clean Condensat). Using its intelligent air circulation principle, it ensures that the S1 effectively utilizes the hot temperatures of the exhaust air, thereby saving up to 30 percent energy. In addition, the SCC cleans the supply and exhaust air and dehumidifies the air. 


It works like this: the SCC removes the stale and humid air along with odors from inside the cabin, the air is then cleaned and dehumidified by the coconut carbon filter with activated carbon carbonate. At the same time, the SCC draws in fresh outside air which is heated by the hot exhaust air passing by, and purified of pollen, house dust, ozone and pollutants through a filter. By collecting the condensate, no unwanted moisture gets into the surrounding area.  


When it comes to the sauna experience, Klafs has also developed interesting options for the S1. Inside you can bathe in your favorite colored light with the optional Bellasensa flush-mounted into the ceiling. Six fascinating natural spectacles are programmed here. The colors can also be set individually.  


Even your individual music tastes can be on request in the sauna - thanks to the RelaxAudio system. Listen to your favorite music here from your smartphone or tablet via Bluetooth, the entire rear wall of the sauna is transformed into a loudspeaker membrane – for a true sound experience.
