Installation Steps
Prepare the Outdoor Location
Select a level outdoor site with sufficient clearance around the sauna's 86-inch by 87-inch exterior footprint. A stable foundation capable of supporting the sauna's installed weight is essential for proper performance and longevity.
Unpack & Organize Components
Carefully unpack and inspect all wall elements, base components, corner posts, ceiling sections, bench parts, glass wall system, door components, lighting, mouldings, heater guard, floor grid, hardware, and included accessories.
Assemble the Base & Structural Frame
Install the base elements, corner posts, wall sections, side cladding, ceiling elements, and mouldings. Ensure all components remain level, square, and properly aligned throughout assembly.
Install the Glass Front System
Position the full tempered glass front wall, install the door frame, mount the 8mm tempered glass door, and secure the metal hinges and premium metal-wood handle according to manufacturer instructions.
Build the Bench System
Install the bench supports, upper and lower bench frames, bench grids, and footrest. The spacious 2-tier bench configuration allows bathers to choose their preferred heat level and seating position.
Install Lighting & Interior Details
Mount the LED backrest assembly, lightshade, heater guard, duckboard floor grid, and finishing mouldings. Verify all interior components are securely fastened and properly positioned.
Electrical Connection & Heater Installation
Connect the LED lighting and install the selected sauna heater according to manufacturer specifications. A licensed electrician should complete all heater wiring, controls, dedicated circuits, and final safety inspections in compliance with local electrical codes.
Final Inspection & First Heat Cycle
Verify glass alignment, door operation, bench stability, lighting functionality, heater guard placement, floor grid fitment, and trim installation. Perform an initial heat cycle before first use to condition the sauna interior and confirm proper operation.
Outdoor sauna power —
heater-ready, LED-integrated, and professionally installed
The Auroom Mira L is a large-capacity outdoor sauna designed for electric heater integration and requires careful electrical planning based on the selected heater model (Saunum AIR L 10, HUUM DROP 9, or Harvia Cilindro PC110E). Because of its 5-person volume and outdoor installation environment, proper circuit sizing, heater control setup, LED lighting connection, and weather-safe wiring are essential for safe and reliable operation.

Good luck getting
Costco on the phone.
Most premium sauna purchases come with a phone tree. Ours comes with a person. When something goes sideways — a lost shipment, a freight delay, a damaged panel, a question at 9 PM on a Wednesday — you text us. We text back. Same day, often the same hour. We call the manufacturer. We chase the freight company. We solve the problem while you go on with your life. That's what we mean by boutique concierge service. It's the difference between buying a sauna and being supported through one.
Lost in Transit
If your shipment goes missing, we're on the phone with the freight carrier before you even know there's a problem. You don't chase anyone. We do.
Shipping Delays
You hear about delays from us, before you wonder. We monitor every shipment, every day, until it's in your driveway.
Manufacturer Defect
If a panel arrives damaged or a heater malfunctions, we escalate directly to Leil, HUUM, or Harvia on your behalf. You don't make a single warranty call. We handle the back-and-forth.
A Question at 9 PM
Text us. Email us. Call us. You get a real answer from a real person — not a chatbot, not a ticket number, not a 48-hour response window.
We're not the cheapest box on the internet. We're the team that picks up the phone after the box is in your driveway. That's what we stand behind — every order, every customer, every day.
