Acadia Bay Sauna

Acadia Bay Sauna is a premier custom sauna design and build company based in Sullivan, Maine — serving all of New England from its Downeast Maine base with bespoke, handcrafted sauna installations for residential and commercial clients. Founded by a builder with over 20 years of construction experience and extensive collaboration with leading architects and designers across the Northeast, Acadia Bay Sauna creates made-to-order sauna experiences tailored to each client’s space, aesthetic vision, and wellness goals. The company works with internationally respected sauna brands including Harvia, Saunum, and Humm for heaters and technology, while sourcing cedar, hemlock, and spruce exclusively from locally based lumber mills throughout the Northeast. The result is a sauna that is both technically excellent and deeply rooted in the natural materials of the Maine and New England landscape. Residential installs can be built within any existing footprint — converting spare rooms, basements, garage spaces, or outbuildings into stunning sauna sanctuaries. Commercial installations are available for wellness centers, hotels, spas, and athletic facilities looking to captivate clients with a signature sauna experience. Optional interior enhancements include Himalayan salt accent walls, integrated tile and stone work, water features, and custom lighting. Located in Sullivan with easy access to Acadia National Park and the Blue Hill Peninsula, Acadia Bay Sauna is deeply connected to the natural landscape that inspires the finest sauna traditions.
