The Blumenberg automatic refill system for sauna plunge pools with plastic insert ensures controlled, hygienic fresh water refilling after each use. The system is designed for professional sauna use and supports a consistently high water standard – efficiently, unobtrusively, and with minimal maintenance.
Function & use – Blumenberg automatic refill system for sauna plunge pools with plastic insert
After each immersion bath, a defined amount of fresh water is automatically refilled. The run-on time can be individually adjusted, allowing precise adaptation to the frequency of use and pool volume. The water level sensor reliably monitors the fill level, while the solenoid valve precisely controls the amount of water.
The ball valve on the drain replaces the classic plug and makes emptying and maintenance easier. The technology is housed in a wall connection cover that is open at the back, allowing easy access to all components.
The system is controlled via a 230 V connection with a residual current device and a separate circuit breaker. The water connection is professionally routed directly to the solenoid valve via a pipe breaker (backflow preventer) and a shut-off valve. The system is specially designed for plunge pools with plastic inserts.

Customization & genuine flexibility
Every tub, every vat, and every accessory is manufactured to order.
Dimensions, height, wood type, technology, fixtures, and cladding are customized to suit individual requirements.
No compromises on standardization—just tailor-made solutions for real spaces.
Solid wood construction throughout (no cladding necessary)
The tubs and vats are made entirely of solid wood, with the same high quality inside and out. No plastic aprons, no additional cladding. Can be placed anywhere in the room, maximum design freedom, a real piece of furniture instead of a sanitary product.
High-quality hygienic sealing for underwater applications
The specially developed hygiene sealant is: physiologically harmless, highly moisture-resistant, elastic (works with the wood), chemical- and temperature-resistant, hygienically tested according to DIN 25415 ("very good"). In practice, it is comparable to or better than sanitary acrylic, but with the warmth and feel of wood.
Retreadable steel belted tires (a true quality factor)
Unlike many inexpensive or imported products, the steel band tires can be retensioned. This is crucial, as wood expands and shrinks. Permanent tightness, even with fluctuations in humidity.
Over 125 years of cooperage experience (since 1896)
Blumenberg has been manufacturing solid wood vessels for permanent contact with water for generations. This long-standing experience avoids typical beginner's mistakes with wooden bathtubs and immersion tubs and ensures proven durable, leak-proof constructions.

Kleine Sauna, grosses Glück!
Wir haben die AWT E1103B Hemlock Sauna in unserem neuen Anbau im Chalet Baumfuchs im Wallis installiert – und sind begeistert! Die Lieferung erfolgte punktgenau am vereinbarten Tag. Den Aufbau habe ich (weiblich, 40 Jahre) gemeinsam mit meiner 12-jährigen Tochter problemlos geschafft. Lediglich beim Einsetzen der schweren Rückwand brauchten wir kurz Unterstützung von kräftigeren Armen.
Die elektrische Installation wurde von einem lokalen Elektriker vorgenommen. Insgesamt wäre der gesamte Aufbau aber niemals so reibungslos verlaufen, wenn wir nicht den großartigen Support über WhatsApp durch Franz vom FinAWellness store erhalten hätten. An dieser Stelle nochmals ein herzliches Dankeschön. Das ist noch wahrer Kundenservice!
Wir lieben unsere kleine, aber feine Sauna. Nach einem Ski- oder Wandertag die wohlige Wärme zu genießen und dabei die wunderschöne Aussicht zu bewundern – einfach perfekt. Klare Empfehlung!
Kleiner Tipp: Wir haben uns noch einen Hocker dazu gekauft um die Beine etwas erhöht abzulegen.

Bin sehr zufrieden mit meiner Dampfdusche von AWT
Hallo, mit dem Umbau des Bades haben wir uns diese Dampfdusche eingebaut. Auch im Vergleich zu anderen Anbietern, hat die AWT Dampfdusche hinsichtlich Design und Ausführung das Rennen gemacht. Die Beratung war gut und auch die Lieferung auf das gewünschte Datum hat tadellos funktioniert. Beim Einbau hat mir ein Installateur vor Ort geholfen. Auch wenn ich handwerklich nicht ungeschickt bin, wäre es schon eine kleine Herausforderung gewesen! Handbrause und Regendusche funktionieren einwandfrei, aber auch das Herz der Dampfdusche, der Dampfgenerator, tut seine Dienste. Das Aufheizen auf meine eingestellten 40° dauert ca. 15 Minuten. Die Kabine ist dicht, die Lichteffekte funktionieren und auch die Verbindung mit Bluetooth Geräten funktioniert einwandfrei. Nach jetzt ca. einem halben der Inbetriebnahme könnte ich keine Mängel feststellen und wir sind sehr zufrieden.

Sauna 1111XL
Sauna 1111XL gekauft und pünktlich geliefert bekommen. Die Sauna wird in mehreren großen Paketen angeliefert, da sind ein paar Helfer beim entladen und vertragen der Elemente gut zu gebrauchen, Der Aufbau der Sauna ist logisch aber die Anleitung ist eher rudimentär, dafür ist jedoch der Support von FinA sehr gut, besonders durch die kompetente Frau Annemarie, Sie findet immer eine Lösung und ist ausgesprochen freundlich und hilfsbereit. Jederzeit gerne wieder! Die Sauna selbst ist wirklich schön die Zuschnitte der Baugruppen passen saugend und funktioniert wie erwartet, wir haben eine große Freude damit.
Das es das noch gibt !!!
Bei der zur Zeit herrschenden Wetterlage ist meine Wärmepumpe vom Spa komplett eingefroren und glich mehr einem Eisblock als einer Wärmepumpe. Obwohl nicht bei diese Firma gekauft ( großer Fehler ) wurde ich kompl betreut und dank Support sofort weitergeholfen! Besonders möchte ich hier den Einsatz von Frau Annemarie hervorheben der wirklich in der heutigen Zeit seines gleichen sucht ! Vielen Dank !! In Zukunft weiß ich wo man Sauna und Spa kaufen muß !!!

Die Holzwanne entspricht voll meinen Erwartungen. Während des Bestellvorgangs wurde ich super betreut - so wurden alle meine gewünschten Anpassungen ausgeführt. Leider entstand bei der Lieferung ein kleiner Transportschaden. Dieser konnte.aber unkompliziert und zur vollsten Zufriedenheit behoben werden - Top Service - besten Dank
