ELECTRICAL SPECS
Overview
This sauna requires a dedicated 240V, 50-amp circuit run from your main breaker panel (6 AWG copper wire).
Factory Pre-Wiring
The heater, temperature sensor (if applicable), control unit, and lighting are factory pre-wired into an integrated 50-amp subpanel with disconnect.
Installation Requirements
- Dedicated 240V, 50-amp breaker
- 6 AWG copper wire
- Licensed electrician required for final connection
Labor Savings
Unlike traditional sauna kits, internal electrical work is completed at the factory. This typically reduces installation time by 8-hours, removes all technical complexity compared to field-wired systems, and saves on average $1,000 in installation costs.
*Commercial Installations
Three-phase or 208V systems require specialized heaters and compatible control units. Please contact us directly for commercial specifications, engineering review, and pricing.
SHIPPING & DELIVERY
WHITE-GLOVE DETAILS
Your sauna is delivered fully assembled by a professional team experienced in transporting and placing large structures. We utilize commercial-grade equipment including F-550 trucks with 32′ trailers and semi-trucks with 40′–48′ trailers, depending on your model and location. Every delivery is handled with the same level of care and precision used during construction.
Upon arrival, your sauna is carefully offloaded and placed directly onto your prepared foundation. Included with all deliveries, we use specialized Mule equipment to navigate tight spaces and ensure accurate placement exactly where you want it.
SHIPPING COVERAGE
Shipping is included for qualifying sauna models within a 1,000-mile radius of ZIP code 21740.
For locations beyond this range, delivery is quoted based on distance and typically runs at approximately $3 per mile beyond the included radius. Please reach out to our team for a precise quote based on your location and structure.
Custom-sized units may not qualify for free shipping. Our team will always work to optimize delivery logistics and minimize cost wherever possible.
SITE ACCESS & PLACEMENT
A smooth delivery depends on proper site preparation and accessibility. Your site must be fully ready prior to arrival, including:
- A completed and level foundation
- Clear access for truck, trailer, and placement equipment
- Adequate space for maneuvering and offloading
Properties with limited access, tight entry points, or steep elevations may require crane assistance for final placement. Crane services are not included in standard free white-glove delivery.
Send us a video walk through of your property's access and we'd be happy to review it to determine the best delivery approach.
