THE LEIL® EXPERIENCE
A more intentional way to sauna
Rooted in Estonia, Leil® Saunas brings together Nordic craftsmanship, thoughtful design, and the simple ritual of heat and stillness.
Each sauna is designed to feel as considered as the space around it — with clean architectural lines, carefully selected materials, and a focus on creating an environment where you can slow down, reset, and return to what matters.
Leil® believes a sauna should be more than another piece of wellness equipment. It should become a lasting part of the home and a ritual you look forward to returning to for years to come.
Designed with purpose. Built to belong.
Leil® Saunas are created with a clear, modern design language that feels equally at home in a dedicated wellness room, modern residence, mountain retreat, or thoughtfully designed outdoor space.
Rather than overcomplicating the sauna experience, Leil® focuses on premium materials, refined proportions, and functional details that support comfort, durability, and everyday use.
Select models can also be personalized with lighting, heater options, windows, and other upgrades, allowing you to create a sauna experience that fits both your space and the way you want to use it.
LEIL® SAUNAS · CELTO COLLECTION
Bring the warmth of traditional sauna bathing into your everyday life. The Leil® Saunas Celto Collection combines generous glass, natural wood interiors, and clean architectural lines to create an inviting outdoor retreat.
Available in two sizes, Celto offers a practical way to make sauna part of your home. Its compact design fits smaller outdoor spaces, while bronze glazing creates an open interior that feels connected to the landscape around you.
ROOTED IN ESTONIA
Rooted in Estonia, Leil® Saunas brings traditional sauna culture together with modern design and craftsmanship.
The name leil describes the warmth and steam released when water meets hot sauna stones. At its heart is a simple ritual: taking time to pause, enjoy the heat, and reconnect.
Celto brings that spirit home with a design that feels welcoming, purposeful, and easy to make your own.
LIGHT & CONNECTION
Generous tempered bronze-glass windows welcome natural light and preserve a connection to your surroundings. Whether your sauna overlooks a garden, a wooded backyard, or a quiet patio, the glazing helps the interior feel open and inviting.
A matching bronze-glass door, premium handle, and black hinges complete the understated design.
STRUCTURE & CRAFT
Celto’s walls, ceiling, and floor are built with 60 mm CLT panels. These cross-laminated timber panels form the structure of the cabin and are central to the collection’s efficient assembly system.
An EPDM roof covering helps protect against moisture, while a treated timber base frame supports the structure. Together, these components create a practical foundation for your outdoor sauna retreat.
NATURAL COMFORT
Inside, two-level aspen benches and a wide, single-board backrest create a comfortable place to settle in.
The tiered layout brings a familiar element of traditional sauna design into a compact cabin, while the wood’s natural character gives the interior a warm, understated finish.
Four ventilation openings support airflow through the sauna.
THOUGHTFULLY ENGINEERED
Celto arrives as an unassembled DIY kit with a detailed assembly manual. Its panel-based construction is designed to make on-site assembly straightforward.
Leil® Saunas estimates approximately 4–6 hours for cabin assembly. Actual timing depends on experience, crew size, and site readiness; allow additional time for site preparation, exterior finishing, and heater installation.
Some components are heavy and require two or more people for safe handling.
