Frequently Asked Questions
Can you install a sauna kit I already bought?
Yes. If you’ve purchased a pre-built or modular sauna, our installers can handle professional assembly, electrical connections, ventilation checks, and final testing to ensure everything operates safely and efficiently.
Are saunas energy efficient for Long Island homes?
Modern saunas are designed to be highly efficient. Infrared saunas use minimal electricity, while traditional saunas perform well when properly insulated and paired with modern controls. We help Long Island homeowners choose options that balance comfort, performance, and energy usage.
Do you work only on Long Island, or nearby areas as well?
We serve homeowners and businesses across Long Island, including Nassau County and Suffolk County. Our team regularly works in coastal communities, suburban neighborhoods, and estate properties throughout the region.
Do I need a lot of space to add a sauna to my home?
Not at all. Saunas can be designed for compact spaces such as bathrooms, spare rooms, or home gyms, as well as larger basements and outdoor areas. We help maximize comfort and functionality regardless of available square footage.
What types of saunas do you install on Long Island?
We design and install indoor saunas, outdoor saunas, infrared saunas, steam saunas, commercial saunas, and offer pre-built sauna installation services. Each sauna is planned with Long Island’s climate, humidity levels, and building conditions in mind.
What health benefits do homeowners get from regular sauna use?
Routine sauna use can support relaxation, muscle recovery, circulation, improved sleep, and stress relief. Infrared saunas are often chosen for joint and muscle comfort, while steam saunas are popular for skin care and respiratory support. Many Long Island clients incorporate sauna sessions into their weekly wellness routines.
What does a custom sauna typically cost on Long Island?
Pricing depends on sauna type, size, materials, and installation requirements. Compact indoor saunas often begin in the $6,000–$8,000 range, while outdoor or steam saunas commonly range from $10,000–$20,000+. Commercial projects are priced individually. We provide clear, detailed estimates before any work begins.
What sets you apart from other sauna contractors on Long Island?
We focus exclusively on sauna design and installation—this isn’t an add-on service. Our clients work directly with experienced specialists, receive custom-built solutions, and benefit from premium materials and ongoing support long after installation is complete.
Are saunas safe for children and older adults?
Yes, when used properly. Children should use saunas for shorter sessions at lower temperatures and always with supervision. Older adults often prefer infrared or lower-heat options. We include safety features such as timers, proper ventilation, comfortable bench heights, and easy-access doors.

Can a sauna be installed in a condo or apartment on Long Island?
In many cases, yes. Compact and infrared saunas are especially popular for condos and apartments. We verify electrical capacity, ventilation, and any HOA or building requirements before moving forward.
Is it safe to use a sauna every day?
Yes, daily sauna use is generally safe when practiced responsibly. Most users enjoy sessions lasting 15 to 30 minutes. During installation, we review proper usage guidelines to ensure comfort and safety for everyone in your household.
How long does a typical sauna installation take on Long Island?
Most residential sauna projects are completed within 1 to 3 weeks, depending on the design and site conditions. Pre-built sauna units can often be installed in a single day. Larger or commercial installations may require additional time for planning and coordination.
Will my home need electrical or ventilation upgrades?
Most saunas require a dedicated electrical circuit and proper airflow. We evaluate your existing setup and coordinate with licensed electricians when upgrades are necessary to ensure safe, code-compliant installation.
How much maintenance does a sauna require?
Sauna upkeep is straightforward. Regular cleaning of benches and walls, allowing airflow after use, and periodic sealing for outdoor saunas help keep everything in excellent condition. We provide detailed care instructions and ongoing support if needed.

Why choose an outdoor sauna for a Long Island property?
Outdoor saunas offer a unique, year-round relaxation experience—from cool autumn evenings to winter nights. When properly built, they withstand coastal weather conditions while adding character and functional outdoor wellness space.
Can adding a sauna increase my home’s value?
Yes. Wellness-focused features are increasingly desirable, and a professionally installed sauna can enhance both enjoyment and resale appeal—especially in competitive Long Island housing markets.
Are infrared saunas a popular option on Long Island?
Very much so. Infrared saunas are favored for their energy efficiency, gentle heat, and compact design, making them ideal for homes where space or electrical capacity is a consideration.
What materials and heaters are used in your saunas?
