Whether your project is a residential sauna going beneath a staircase or a large commercial sauna for a professional sports team, the basic questions remain the same:
When Custom Is The Best Choice
Custom saunas are perfect for MANY applications and can be done during new construction or renovations. Residences, hotels, corporate fitness centers, health clubs, apartment buildings, and more — wherever a sauna is wanted, we can help bring it to life. A special design or unique location doesn't mean you have to settle for less.
Your options are unlimited — innovative use of glass windows and doors, unusual angles, unique bench configurations, and so on. Your design, in partnership with our experience and quality craftsmanship, assures unmatched form and function. If you can design it, we can build it.
Start With Your Local Sauna Dealer
Bringing a custom sauna to life is a team effort. You'll start by enlisting the help of a local Finnleo dealer. They will help you (and/or your designer) navigate the custom sauna design process; by understanding your space, your vision, and our capabilities, they can layout your in-home sauna.
From there, we review, create a CAD drawing, confirm manufacturability, and occasionally offer suggestions for improvement. With your approval, we custom manufacture the sauna pieces to your specifications. A complete sauna kit is then delivered, ready for installation.
Your dealer's contracting team, or yours, takes over from here, installing the sauna onto your framed walls. When it's done, you'll have a custom built-in sauna made just for your home.
Designer Saunas
This series of saunas was designed to enhance the elegance of a standard Finnish sauna. As sauna enthusiasts add these into their home, many are looking for a beautiful, upscale design to complement or even enhance the beauty in their home.
With beauty in mind, we prioritized performance. Each Designer sauna features a proven sauna heater, with our state-of-the-art SaunaLogic2® control. Interior wall panels are hand-selected and built to last.
Designer Sauna Specifications
Each Designer sauna has its own unique features, but they all have the following in common:
Available as a standard layout, or a mirror image layout.
Custom Free-Standing Indoor Saunas
Our custom panel-built saunas, called Sisu, are a great solution when you're looking for a uniquely designed stand-alone sauna to set into your existing indoor space; maybe your gym, wellness center, spa, basement, spare room, or other.
Personalize with design options that complement and enhance your sauna's final destination. Wood selection, door design, window placement, electric heater, and more are design decisions you get to make.
This process begins with our local dealers, who guide you through the design, measurements, delivery, and installation. We manufacture the panels perfectly to your specifications, and deliver pre-built panels and components, ready for final assembly.
Sisu Sauna Kits
Every Sisu sauna design starts from a standard package, which you can build from to craft your preferred sauna experience. The final delivery will include the following, for easy assembly:
Finnleo Sauna Heaters
Designed and built in Finland, with performance and safety testing in North America, Finnleo sauna heaters power your sauna beautifully, reliably, and remotely. Whether wall-mounted or floor-standing, electric or wood-burning, there’s a Finnleo heater engineered for every sauna — from a small home retreat to a large commercial facility.
We put more rocks in direct contact with the heating elements to exceed even our own high performance standards, delivering the penetrating heat and soft steam that define an authentic Finnish sauna experience.
Custom Sauna Controls
The SL2 control is feature-rich giving sauna users flexibility to control their sauna easily, from anywhere. The glass touch screen provides a modern and easy to use interface to control time, temperature, RGBW lighting, and can even work with our Bluetooth sound system.
Within the app, you can adjust temperature, choose the light color (built-in RGBW light control with dimmer), turn Bluetooth on/off (for use with optional SL2 soundbar), set a delay time (up to 24 hours), use the 60-minute timer, create daily/weekly/monthly schedules, and more. The SaunaLogic2 mobile app is available for the iPhone and Android smartphones, iPads/tablets, and works with Google Home, Alexa and Siri. The Administrator of the app can create a “Family” and add as many users as they wish.
Custom Sauna Design
From interior wood species and bench configurations to backrest styles, door designs, lighting, and more — every detail of your custom sauna can be personalized to your taste and space. Explore the full range of options available for your Finnleo custom sauna.
