Sauna Room 101: Types, Materials, and Smart Features to Know Before You Buy

A sauna room is a dedicated enclosed space designed for heat therapy, typically built from wood and equipped with either a traditional stove or infrared heating system. If you are exploring saunas for the first time — whether for a home, hotel, spa, or commercial wellness project — this guide explains the core concepts you need to understand before making a purchase decision.

What Is a Sauna Room?

A sauna room is a wood-built enclosure that generates dry or low-humidity heat for therapeutic sweating, muscle relaxation, improved blood circulation, stress relief, and temperature therapy. Sauna rooms are used in private residences, commercial clubs, wellness clubs, leisure facilities, hotels, and boutique guesthouses.

Most modern sauna rooms fall into two heating categories: traditional saunas, which use a stove (often with sauna stones) to heat the air, and infrared saunas, which use far infrared heating plates to warm the body directly. Some models combine both approaches.

The Global Sauna Market: Why Awareness Is Growing

The global sauna market was valued at USD 954.3 million in 2025 and is projected to reach USD 1,556.8 million by 2033 (Grand View Research). The United States alone generated USD 250.8 million in sauna revenue in 2024, representing about 21.8% of the global total (Topture / Technavio).

Two trends help explain this growth. First, the residential segment dominated the market with a 58.92% share in 2025, driven by home-based wellness trends (Grand View Research). Second, while traditional saunas still hold the largest product share at 42.79%, infrared saunas are the fastest-growing segment with a 7.5% CAGR (Grand View Research).

For buyers, this means demand is no longer limited to hotels and spas. Homeowners, guesthouse operators, and commercial wellness clubs are all active buyers — and their needs differ significantly.

Traditional vs. Infrared vs. Hybrid Sauna Rooms

Understanding the heating method is the most important first step in choosing a sauna room. Each approach changes the installation requirements, power consumption, user experience, and price range.

Traditional Finnish Sauna Room

Traditional saunas use a stove — often a Harvia stove — to heat air and sauna stones. Users pour water over the stones to create steam and higher humidity. These saunas are well-suited for users who want the classic Finnish experience.

OCEAN FUTURE offers traditional-style indoor sauna rooms with Harvia stoves. For example, model OFS05-1 uses an 8kW Harvia stove (BC80E) with a total power of 8000W, while model OFS05-2 uses a 3.5kW Harvia stove (BC35E). Model OFS07-2 combines a Harvia 6kW stove (BC60E) with a far infrared heating box, reaching a total power of 8000W + 800W.

Infrared Sauna Room

Infrared saunas use far infrared heating plates or panels to heat the body directly rather than heating the surrounding air. They typically operate at lower air temperatures, warm up faster, and often include entertainment features such as speakers, Bluetooth, and colorful lighting.

OCEAN FUTURE produces a broad infrared sauna room series — models OFS06A-1, OFS06A-4, OFS06A-5, OFS06B-1, OFS06B-2, OFS06B-3-1, OFS06B-3-2, and OFS06B-4 — with total power ranging from 1200W to 3000W. These models are built from hemlock, aspen, and red cedar, and typically feature an AV1 control system, painted surfaces, tempered glass, wood handles, speakers, and FM/Bluetooth/USB connectivity.

Hybrid Infrared and Traditional Sauna Room

Hybrid sauna rooms combine a traditional stove with infrared heating panels or boxes. This gives users the option of a classic steam experience or a gentler infrared session in the same unit.

OCEAN FUTURE's model OFS07-2 is an example: it pairs a Harvia 6kW stove (BC60E) with a far infrared heating box, controlled by an MXD2022 system. It includes two speakers, a colorful lamp under the seat, a 4000K lamp, and accessories such as a wooden bucket, spoon, sandglass, hygrothermograph, and one set of sauna stones.

Indoor vs. Outdoor Sauna Rooms

Where you install the sauna room is the second major decision. Indoor and outdoor units serve different project requirements and come with different structural features.

Indoor Sauna Rooms

Indoor sauna rooms are designed for installation inside a building — in a basement, bathroom, home gym, hotel suite, or spa area. They typically require a flat, dry, ventilated space and access to the appropriate power supply.

OCEAN FUTURE's indoor models include OFS01-1, OFS01-2, OFS01-3, OFS02-1, OFS02-2, OFS02-3, OFS03-1, OFS03-2, OFS03-3, OFS05-1, OFS05-2, OFS05-3, OFS07-1, OFS07-2, and OFS08-1. Most are constructed from hemlock, aspen, and red cedar, and feature tempered glass doors, wood handles, lighting systems, and FM/Bluetooth/USB or WiFi connectivity. For example, model OFS03-1 uses far infrared heating plates, an MXD2022 control system, and features a square colorful lamp, colorful light belt, and door eaves lighting. Model OFS08-1 is a smart indoor sauna room with WiFi and Bluetooth, rated at 220V/50Hz.

Outdoor Sauna Rooms and Cabins

Outdoor sauna rooms are built to withstand variable climate conditions, including sun exposure, rain, and low temperatures. They are often installed in private backyards, hotel gardens, guesthouse grounds, or resort areas. Key structural features include a weatherproof roof (often called a pentroof) and corrosion-resistant materials.

OCEAN FUTURE's outdoor models include OFS06A-3-1, OFS06A-3-2, OFS06A-5, OFS06B-5, OFS06C-1, OFS06C-2, OFS06C-3-1, OFS06C-3-2, OFS06C-4, OFS06C-5, OFS12-2-T, and OFS05-3-T. The OFS06C series is designed with an outdoor pentroof, tempered glass, wood handle, lamp and colorful light, two speakers, FM/Bluetooth/USB connectivity, and far infrared heating plates and box. Total power ranges from 1800W to 4150W depending on the model. Model OFS12-2-T is an outdoor sauna room with a Harvia 6kW stove (BC60E), the MXD2022 control system, and a 4000K lamp. Model OFS05-3-T adds a waterproof roof, Aluminum Plastic Panel exterior, and a Harvia 8kW stove (BC80E).

Wood Materials: Hemlock, Aspen, and Red Cedar

The wood species used in a sauna room affects the look, durability, and price. OCEAN FUTURE builds its sauna rooms from three main woods: hemlock, aspen, and red cedar.

• Hemlock: a strong, straight-grained softwood that is commonly used in sauna construction because it resists warping and has a clean, light appearance.
• Aspen: a light, smooth wood with low resin content, which helps it stay cool to the touch and resist splintering — an important safety feature for benches and seating.
• Red cedar: a naturally moisture-resistant wood with a distinctive warm color and aroma, often used for both interior paneling and exterior cladding.

Many OCEAN FUTURE units also feature a painted surface, which adds a finished look and helps protect the wood in humid environments. Structural components typically include tempered glass doors, wooden handles, and — on stove-equipped models — a wooden stove frame.

Smart Sauna Room Features and Connectivity

Modern sauna rooms are no longer just heated wooden boxes. Many buyers now expect integrated entertainment, lighting, and smart controls. Understanding these features helps you evaluate whether a product fits your users' expectations.

• Control systems: OCEAN FUTURE uses two main control systems — AV1 and MXD2022. AV1 is common on infrared models; MXD2022 is used on many traditional, hybrid, and smart indoor models.
• FM/Bluetooth/USB/WiFi: Most models include FM radio and Bluetooth. Smart indoor models such as OFS08-1 add WiFi connectivity; models with MXD2022 control typically support WiFi as well.
• Speakers: Most OCEAN FUTURE sauna rooms include one or two speakers for audio output.
• Lighting: Common lighting features include square colorful lamps, colorful light belts on the back rest or ceiling, door eaves lighting, 4000K lamps, and colorful lamps under the seat.
• Accessories: Stove-equipped models often come with a wooden bucket, spoon, sandglass, hygrothermograph, and one set of sauna stones.

Typical Applications and Use Cases

Sauna rooms are installed in a wide range of settings. The most common application scenarios for OCEAN FUTURE products are the hotel & hospitality industry, guesthouses, wellness & commercial clubs, and spa facilities. These units are also used in residential home saunas, private backyard saunas, and club wellness projects.

Residential Home Sauna Room

Homeowners typically prefer compact indoor infrared models or small outdoor cabins. A residential sauna room may be used daily for stress relief and muscle relaxation. Smart features such as WiFi, Bluetooth speakers, and colorful lighting are popular in this segment.

Hotel and Boutique Guesthouse Sauna Rooms

Hospitality operators need sauna rooms that are durable, easy to maintain, and visually appealing. Hotels and guesthouses often install both indoor sauna rooms near spa areas and outdoor sauna cabins in garden or pool areas. Because guests expect a premium experience, lighting, audio, and temperature control matter as much as core heating performance.

Commercial Club and Wellness Facilities

Wellness clubs, commercial clubs, and leisure facilities typically need larger or multiple sauna units. They may choose traditional stoves for the authentic Finnish experience, infrared models for quicker sessions, or hybrid models to satisfy both preferences. Commercial operators also need reliable compatibility with control panels and safety thermometers.

Outdoor and Backyard Installations

Outdoor sauna rooms must handle sun exposure, rain, and low temperatures. A weatherproof pentroof, tempered glass, and corrosion-resistant construction are essential. Outdoor models are popular in Australia, Canada, Germany, Spain, France, Mexico, and the United States, with strong demand across European and North American markets.
