Saunum AIR 5
Balanced Climate System- Best for: Bathers seeking balanced temperatures, softer steam, and improved air circulation
- Type: Floor-standing electric sauna heater with integrated air-blending technology
- Power: Approximately 4.8 kW heating output
- Controls: Requires a compatible external Saunum control system
- Why it works: The AIR 5 combines traditional stone heating with Saunum’s climate-equalizing technology to circulate warmth throughout the Baia’s compact two-person interior. It helps reduce temperature differences between upper and lower areas while delivering softer steam, smoother airflow, and greater comfort during longer sauna sessions.
HUUM DROP 4.5
Compact Designer Heater- Best for: Design-focused users who want soft steam and efficient use of limited interior space
- Type: Wall-mounted electric sauna heater
- Power: 4.5 kW heating output
- Controls: Requires a compatible external HUUM control system
- Why it works: The DROP 4.5 combines a sculptural water-drop profile with a generous exposed stone surface, creating a contemporary focal point inside the Baia. Its compact wall-mounted installation preserves valuable floor space while producing gentle, stone-generated steam that complements the cabin’s warm Thermo-Aspen interior.
Harvia Cilindro PC60E
Stone-Rich Tower Heater- Best for: Users seeking traditional heating, generous stone capacity, and adjustable steam intensity
- Type: Floor-standing electric tower heater
- Power: 6.0 kW heating output
- Controls: Requires a compatible external Harvia control system
- Why it works: The Cilindro PC60E delivers reliable heating through its tall, exposed stone column while adding a classic Finnish element to the Baia’s Thermo-Aspen interior. Water can be poured over the top stones for a stronger burst of steam or along the sides for a softer atmosphere, allowing bathers to personalize the heat and humidity of each session.

Installation Steps
Prepare the Indoor Space
Select a dry, level indoor location with enough clearance for the 64.25-inch square footprint. Confirm ceiling height, floor support, ventilation, electrical access, and the desired door-opening direction.
Unpack and Organize Components
Lay out the wall elements, base pieces, ceiling panels, corner posts, bench components, glass, hardware, lighting, and trim. Verify all components before beginning assembly.
Assemble the Base and Walls
Position the base elements, then install the preassembled wall panels, corner posts, cladding, and corner mouldings while keeping the cabin square and level.
Install the Ceiling
Fit and secure the ceiling elements after confirming that all wall panels are properly aligned and stable.
Choose and Install the Door Direction
Configure the reversible door frame for left- or right-hand opening, then install the tempered glass, metal hinges, and metal-wood handle.
Install the Bench System
Fit the bench supports, upper bench frame, contoured ergonomic bench, bench grids, and movable stepping bench for easier access.
Add Lighting and Interior Details
Install the backrest mounting blocks, LED backrest, lightshade, floor grid, heater guard, and finishing mouldings.
Complete Electrical Connections
A licensed electrician should connect the selected sauna heater, control system, sensors, and LED lighting according to local code and manufacturer requirements.
Run the Initial Heat Cycle
Inspect the glass door, benches, lighting, heater guard, and trim before operating the sauna. Complete an initial heat cycle to condition the interior and confirm proper performance.
Compact sauna power —

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.
