Design and build your perfect sauna with guidance from our Finnish sauna expert. Every custom sauna is individually designed and project-managed by our Finnish craftsman, ensuring authentic construction methods and attention to detail that meet traditional Finnish standards.
Whether you’re working with a compact urban space, designing a luxury resort amenity, or creating a backyard wellness retreat, we’ll craft a sauna that fits your exact specifications. Our custom sauna service gives you complete control over dimensions, timber selection, layout, heating capacity, window placement, door styles, and interior configuration.
All custom saunas are built with robust galvanised steel frames and your choice of premium timber. Select pine for its traditional Nordic character and affordability, or upgrade to Grade A+ teak for superior durability in Thailand’s tropical climate. Alternatively, choose pine with a shou sugi ban finish for a striking contemporary aesthetic that offers enhanced weather resistance.
Our Finnish project manager works closely with you from the initial consultation through to the final installation. With decades of experience building saunas in both Nordic and tropical climates, he understands the specific engineering requirements for Thailand’s unique climate, including its heat and humidity. Every design incorporates proper ventilation, appropriate insulation, and timber treatments that ensure your sauna performs beautifully year-round.
Custom saunas are ideal for:
Each custom build includes professional installation across Thailand, from site preparation and base construction through electrical connection and final testing. Our installation team ensures proper assembly, optimal placement, and full functionality before handover.
Your custom sauna includes everything needed for immediate use: an electric heater sized appropriately for your dimensions, a bucket and ladle for water application, a wall-mounted thermometer, a traditional sand timer, integrated lighting, and sauna rocks for steam generation.
Custom builds typically require 3-4 weeks from design approval to delivery, with installation completed within 1-2 days. Rush orders may be accommodated depending on the current production schedule – contact us to discuss your timeline requirements.
We stand behind our craftsmanship with a comprehensive 3-year structural warranty and 1-year coverage on timber and electrical components. This is significantly longer than standard pre-made sauna warranties, reflecting the superior quality of Finnish-designed custom construction.
Perfect for discerning clients throughout Bangkok, Phuket, Pattaya, Chiang Mai, Samui, and all regions of Thailand who want a sauna explicitly designed for their needs.

We deliver and install throughout Thailand:
Please ensure the following before our installation team arrives:
A: Custom sauna pricing varies based on size, timber selection, and features. As a general guide: small custom saunas (up to 120cm) start around THB 200,000, medium saunas (150-190cm) range from THB 250,000-350,000, and large custom builds (210cm+) typically cost THB 400,000+. The configurator on this page provides real-time pricing as you select options. Contact us for a customised quote tailored to your specific requirements.
A: From initial consultation to delivery: typically 4-6 weeks total. This includes 3-5 days for initial design, 1 week for revisions and approval, 2-3 weeks for construction, and 3-7 days for delivery and installation, depending on your location.
A: Absolutely. Our Finnish designer collaborates closely with you to ensure the sauna complements the aesthetic of your property. We can match existing timber finishes, incorporate specific architectural elements, or design contemporary features that integrate seamlessly with modern spaces.
A: Our custom service accommodates virtually any size. The most petite, practical, and custom-built sauna is approximately 100cm x 100cm (a compact sauna for one person). The largest recent project was a 300cm x 400cm commercial sauna for a resort (accommodates 12+ people). If you have specific space constraints or capacity requirements, we can design accordingly.
A: Custom saunas require dedicated electrical circuits. Exact requirements depend on heater size, which is determined by your sauna’s dimensions. Small saunas typically need 220V/15-20A circuits, while larger custom builds may require 220V/30-40A circuits. Our designer will specify the exact electrical requirements during the design phase. We coordinate with your electrician or can arrange a professional electrical installation.
A: Yes, with proper engineering assessment. Our Finnish designer has experience with challenging installations, including rooftops, elevated decks, sloped terrain, and limited-access locations. We’ll evaluate structural requirements, access logistics, and any special foundations needed during the consultation phase.
A: Pine offers traditional Nordic character at the most accessible price point and is ideal for covered or indoor installations. Grade A+ teak offers superior durability and natural weather resistance, making it an ideal choice for fully exposed outdoor locations in tropical climates. Shou sugi ban pine combines affordability with enhanced weather protection and striking contemporary aesthetics. Your choice depends on budget, exposure level, and desired appearance – our designer will recommend the best option for your specific situation.
A: Yes! View the gallery of past custom projects on this page showing various sizes, configurations, and timber options. We’re happy to provide additional photos and details of builds similar to what you’re considering. Some clients also permit site visits to completed installations.
A: Minor modifications can often be accommodated during the build phase. Significant design changes may affect the timeline and pricing. We’ll discuss any requested changes promptly and provide updated timelines/costs before proceeding. Our goal is to deliver precisely what you envision.
A: Absolutely. The configurator covers standard options, but we can incorporate virtually any custom feature: specialty lighting, built-in sound systems, custom benching arrangements, attached changing rooms, exterior storage, unique door designs, panoramic window walls, and more. Discuss your ideas during the consultation.
A: Finnish sauna design emphasises proper heat circulation, optimal bench positioning, appropriate ventilation, and traditional construction methods refined over centuries. Our Finnish designer ensures authentic proportions, correct heating capacity calculations, and construction techniques that create the ideal sauna experience. The difference is noticeable in how evenly the space heats, how comfortable the benches feel, and how long the sauna lasts.
A: The structural warranty covers frame, walls, roof, flooring, door assemblies, and all structural joints against defects in materials or workmanship. One-year coverage includes electrical components, heater elements, controls, hardware, and timber (with required maintenance). See complete warranty details above.
A: Yes. We provide complete maintenance instructions at handover and offer phone/video support for any questions during your sauna’s lifetime. Optional annual maintenance service packages are available, including professional inspection, cleaning, and preventive treatments.
