LEIL COMO 1-120
1-Person Indoor Sauna Kit
Personal sauna. Designed for daily use.
The Como 1-120 is built for those who want a true sauna experience without needing a large space. Designed as a single-person indoor unit, it fits comfortably into home wellness areas, bathrooms, or apartments while still delivering authentic Nordic heat and comfort.
Constructed from 40mm Thermowood with a smooth Aspen interior, it balances durability with a refined, ergonomic feel. The insulated ceiling helps retain heat efficiently, while the elevated base and adjustable ventilation ensure consistent airflow and comfort during every session. It’s a simple, intentional design — built for daily use, not occasional novelty.
A personal sauna, designed for everyday escape.
Minimal space. Maximum focus on you.
The Como 1-120 is built around a different idea of sauna use—not social, not oversized, but intentional and personal. Designed for one, it creates a quiet space where heat, stillness, and routine come together without distraction. It’s not about fitting more people in—it’s about making every session better.
Its clean Nordic design pairs a durable thermowood exterior with a soft, refined Aspen interior. Inside, every surface is shaped for comfort—from the ergonomic bench to the smooth backrest—while the insulated ceiling keeps heat consistent and efficient in a compact volume. The result is a sauna that heats faster, holds temperature better, and feels balanced throughout.
Built for indoor environments, it adapts easily to home wellness spaces, bathrooms, or apartments. Adjustable feet, integrated airflow design, and simple assembly make it practical—while the materials and craftsmanship keep it feeling premium. It’s not just a sauna you install—it’s one you build into your daily routine.
- Single-person layout designed for focused, private sauna sessions
- 40mm Thermowood structure for durability and heat efficiency
- Smooth Aspen interior with ergonomic seating and backrest
- Insulated ceiling and controlled airflow for consistent performance
Technical Specifications
Every measurement, every material, every rating — in full detail.
Which heater fits the Como 1-120 — Harvia or HUUM?
HUUM DROP 4.5 kW
Premium Option- Best for: Design-focused indoor setups and modern interiors
- Output: 4.5 kW — perfectly sized for ~2.7 m³ sauna volume
- Control: UKU controller (Wi-Fi optional for remote start)
- Style: Award-winning drop-shaped design with exposed stone basket
- Why it works: The DROP holds a large volume of stones relative to its size, producing a softer, more consistent löyly (steam). Ideal for a more traditional sauna feel in a compact indoor unit, with optional smart controls for convenience.
Harvia KIP45B (4.5 kW)
Simple & Reliable- Best for: Straightforward installations and everyday use
- Output: 4.5 kW — matched to the Como’s 95 ft³ (2.7 m³) volume
- Control: Built-in mechanical controls (no external controller required)
- Style: Classic wall-mounted stainless steel heater
- Why it works: A proven, no-frills option that’s easy to install and operate. Built-in controls reduce complexity, making it ideal for users who want dependable heat without app connectivity or additional components.

- Adjustable ceiling ventilation module (home ventilation compatible)
- Complete fastener set, seals, and step-by-step installation manual
Installation Steps
Prepare Indoor Space
Choose a flat indoor surface such as tile, sealed concrete, or reinforced flooring. Ensure adequate ceiling height clearance and allow space around the unit for ventilation and maintenance access.
Unpack & Organize Components
Carefully unpack all labeled parts and verify against the included checklist. Position panels in assembly order to streamline installation and avoid misalignment.
Assemble Base & Wall Structure
Install the base frame and adjustable feet first, then connect Thermowood® wall panels in sequence. Secure alignment before locking structural joints for stability.
Install Ceiling, Door & Bench System
Mount the insulated ceiling panels, install the tempered glass door system, and secure the Aspen bench and backrest inside the cabin.
Licensed Electrician Connects Heater
The sauna heater requires a dedicated electrical connection based on the selected unit (Harvia or HUUM 4.5 kW). A licensed electrician must complete wiring to ensure compliance with local electrical codes and safe operation.
Initial Heat Cycle & Wood Stabilization
Run an initial heating cycle with light ventilation to allow the wood to acclimate. A mild natural wood scent is normal and will fade after the first few sessions.
Yes, it runs on 240V —
and we make it simple.
The Como 1-120 uses a standard residential 240V hardwired sauna heater circuit, similar to an electric oven or dryer. With either the Harvia KIP45B or HUUM DROP 4.5 kW heater, the system typically requires a dedicated 20–30 amp breaker. Because of its compact 2.7 m³ volume, it heats quickly and efficiently without excessive power demand.

Good luck getting
Costco on the phone.
Most $8,000 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.
Call (605) 702-4868Not outdoor rated. Designed exclusively for indoor use.
The Leil Como 1-120 is engineered specifically as an indoor sauna and is not rated for outdoor installation. Its Thermowood and Aspen construction is designed to perform in controlled interior environments where it is protected from direct rain, snow, UV exposure, and long-term moisture saturation. When installed indoors, it delivers stable performance, efficient heat retention, and long-term material durability.
The 40mm Thermowood structure is moisture-stable and heat-resistant but is intended for interior climates only. It is not designed for direct weather exposure or continuous outdoor humidity cycles.
The tempered glass door and black hardware are engineered for indoor sauna environments, where temperature and humidity remain controlled and consistent.
The dual-layer insulated ceiling is optimized for heat retention in enclosed indoor spaces, not for external weather resistance or precipitation protection.
Adjustable feet and air-gap design are intended for indoor flooring conditions such as tile, concrete, or sealed surfaces, ensuring stability and even heat distribution.
Integrated ceiling ventilation is designed for indoor air exchange systems and passive airflow within enclosed rooms, not for outdoor wind or environmental exposure.
All materials, including Aspen benching and Thermowood panels, are optimized for consistent heat cycles in protected environments where temperature and humidity can be controlled.
Compact design. Premium interior comfort.
The Como 1-120 uses a carefully engineered dual-wood system designed specifically for indoor sauna performance. Thermowood® forms the structural shell, providing long-term stability and heat resistance, while Aspen is used for all interior contact surfaces to ensure a smooth, cool-touch, and comfortable sauna experience even at high temperatures.
Thermowood® — 40mm Structural Shell
The exterior walls and core structure are built from thermally modified softwood. This process permanently stabilizes the wood by reducing moisture absorption and improving resistance to warping under repeated heat cycles. It ensures long-term dimensional stability even in high-temperature indoor sauna environments.
Aspen — Interior Seating System
All seating, backrest, and interior touchpoints are made from kiln-dried Aspen, chosen for its low thermal conductivity and smooth, splinter-free grain. It stays cool to the touch during sauna sessions, making it ideal for direct skin contact and extended relaxation.
Indoor Climate Stability Design
The wood system is optimized for controlled indoor environments where temperature and humidity are stable. This allows the materials to perform consistently without exposure to rain, UV, or freeze-thaw cycles.
Heat Efficiency & Comfort Engineering
The combination of Thermowood® insulation properties and Aspen’s low heat retention ensures fast warm-up times while maintaining a comfortable interior surface temperature throughout the session.
Open the crate. Everything is pre-cut and ready for assembly.
