ELECTRICAL SPECS

Overview

This garden room is delivered fully pre-wired and requires a single 120/240V, 100-amp feeder connection from your main electrical panel.

Power is supplied via a 100A double-pole breaker using #3 copper conductors (or equivalent) run to the integrated subpanel.

Factory Pre-Wiring

All internal electrical components are completed at the factory and consolidated into a central subpanel, including:

  • Interior lighting
  • Electrical outlets
  • Switches and controls
  • Dedicated circuits for heater and optional equipment

Each unit includes a factory-installed 100-amp subpanel, allowing for a clean, single-point electrical connection on-site.

Installation Requirements
  • Dedicated 120/240V, 100-amp breaker in main panel
  • #3 copper wire (or equivalent), 4-conductor feeder (2 hots, neutral, ground)
  • Conduit run from main panel to structure (underground or exterior)
  • Connection to the integrated subpanel by a licensed electrician
Labor Savings

Unlike other garden room or sauna kits, internal electrical work is completed at the factory. This typically reduces installation time by 8-hours+, removes all technical complexity, and saves on average $1,000 or more 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 structure is delivered fully assembled by a professional team experienced in transporting and placing large buildings. 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 structure 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

Free shipping is included for qualifying garden room models within a 1,000-mile radius of ZIP code 21740.

For locations beyond this range, delivery is quoted based on distance and size and typically runs at approximately $5-$10 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.

NEED HELP?

We’re here to make delivery seamless. If you have questions around site prep, access, custom sizing, or shipping costs, reach out anytime. Our team will guide you through the process and ensure everything is set up for a successful install.
