ChineseWe Design Complete Wellness Environments
From a Single Sauna to a Complete Wellness Environment
Celsium designs and builds bespoke wellness spaces — from an individual sauna to private spas, hospitality wellness areas, architectural wellness buildings and glamping retreats.
Every project begins with a conversation about your space, your goals and the experience you want to create.
From concept to commissioning, our team manages the entire process with architectural precision, controlled manufacturing and meticulous attention to detail.
BEYOND THE SAUNA
Your Wellness Environment, Designed as One
A bespoke sauna is often where a Celsium project begins. For many clients, it becomes the foundation for something larger — a private spa, a hospitality wellness area, or a complete architectural retreat.
Celsium designs and builds each project as a single, coherent wellness environment, rather than a collection of separate rooms and equipment.
WHAT WE BUILD
Four Ways We Work With You
Private Wellness
A bespoke sauna, hot and cold experience, or a complete private spa built into your home or garden.
Hospitality & Spa
Wellness areas for hotels, resorts and spas, designed to perform under daily guest use.
Wellness Architecture
Purpose-built wellness buildings, developed as architecture in their own right.
Glamping & Retreats
Freestanding wellness pods and cabins for retreats, campsites and nature destinations.
THE CELSIUM ECOSYSTEM
A Complete Wellness Ecosystem
Every Celsium project can draw from the same set of wellness elements, combined to fit the space and the experience.
Heat
Traditional sauna, infrared, steam.
Hot & Cold
Cold plunge, ice bath, contrast therapy.
Recovery
Relaxation areas, red light therapy, experience showers.
Atmosphere
Integrated lighting, sound, materials and finishes.
Control
Smart controls and system integration.
FOR ARCHITECTS & DESIGNERS
Working With Architects
Celsium partners with architects, interior designers and developers as a technical and manufacturing partner for wellness spaces.
We work from early concept through technical development, engineering and manufacturing, adapting to the architectural language of each project.
Our No.5 architectural system and interior wellness solutions can be specified and integrated into project drawings from an early stage.
PROJECT SCALE
From a Single Room to a Complete Retreat
Celsium projects range widely in scale and complexity.
A single bespoke sauna or cold plunge.
A private spa combining several wellness elements.
A hospitality wellness area for a hotel or resort.
An architectural wellness building developed as its own structure.
A multi-unit glamping or retreat development.
Each project is approached with the same level of design and manufacturing discipline, scaled to fit its purpose.
MATERIALS
Built From Considered Materials
Every Celsium project is built using carefully selected woods, glass and architectural materials, chosen for durability, atmosphere and long-term performance in wellness environments.
Material choices are adapted to each project’s architecture, climate and interior character.
MADE IN EUROPE
Designed and Manufactured in Europe
Celsium designs and manufactures every project in Europe, under controlled production conditions, with the same attention to detail from the first prototype to full-scale delivery.
Since 1994, this approach has shaped wellness spaces delivered worldwide.
