Custom Outdoor Sauna with Shower and Multi-Use Space

Modern custom outdoor saunas are no longer limited to a simple wood sauna cabin. For residential backyards, hotels, resorts, and wellness projects, customers are increasingly looking for complete outdoor wellness spaces that combine sauna, shower, changing, lounging, and other functions within a limited footprint.

Custom Outdoor Sauna with Three Integrated Functional Areas

Alphasauna’s ALP-260609C is a custom outdoor sauna designed for multi-functional outdoor wellness spaces. Measuring approximately 3600 mm Width × 1800 mm Depth × 2100 mm Height, the unit is divided from left to right into a sauna room, an open shower area, and a customizable multi-purpose space.
The structure is built with Thermo Pine and finished with a modern black exterior coating. Large panoramic glass panels, integrated LED lighting, and a waterproof roofing system complete the design.
More importantly, this is not a fixed-function standard sauna cabin. Alphasauna can customize the dimensions, wood species, exterior finish, glazing, interior layout, and functional configuration according to each project.
For Alphasauna, this product represents more than an outdoor sauna. It combines our capabilities in wood processing, sauna manufacturing, space planning, and OEM/ODM customization to create a multi-functional outdoor wellness unit.
Compared with a traditional single-purpose outdoor sauna, this layout provides more functions within the same footprint. Instead of building separate structures for a sauna, shower, and changing or lounge area, customers can integrate multiple functions into one outdoor structure, making better use of available space while maintaining design flexibility.
The clean rectangular form also gives the outdoor sauna a contemporary architectural appearance, allowing it to fit naturally into modern residential backyards, hotels, resorts, and wellness projects.

Sauna, Shower, and Customizable Multi-Purpose Space

Each of the three areas serves a different purpose.
The sauna occupies the left section and features two-tier sauna benches, a wooden backrest, and integrated LED lighting.
The center section is an open shower area. Waterproof materials are used in areas exposed to water and moisture, allowing users to shower directly after their sauna session.
The right section is intentionally left open for customization rather than being assigned to a fixed function.
Depending on the project or end-user requirements, it can be configured as:
● A private bathroom
● A changing room
● A lounge area
● A relaxation space
● A storage area
The same base structure can be adapted into different custom sauna configurations for different markets and projects.

A Natural Flow from Sauna to Shower

The three areas are not simply placed next to one another. They are arranged to create a practical and natural user flow.
Users can enter the sauna first, move directly into the center shower area after the session, and then use the right-side space for changing, relaxing, or other customized functions.
For residential backyards, this layout creates a more complete home wellness experience.
For hotels, resorts, and spa projects, the right-side area can be further customized according to the project concept, turning the outdoor sauna unit into a more complete and connected wellness space.

Custom Outdoor Sauna Materials and Architectural Design

A modern custom outdoor sauna needs to address more than sauna performance. Space planning, materials, lighting, weather protection, and overall architectural style all need to work together.
This sauna combines the sauna room, open shower area, and multi-purpose space within one structure, using natural wood, a black exterior finish, large glass panels, and a waterproof roofing system to balance functionality, aesthetics, and outdoor durability.

Sauna Interior Designed Around the User Experience

The sauna interior features two-tier sauna benches, a wooden backrest, and concealed LED lighting.
The two-tier bench design makes efficient use of vertical space while providing different seating levels. The bench, backrest, and lighting positions are planned as part of the overall sauna structure and can be adjusted according to the sauna dimensions and interior layout.
The wooden backrest matches the natural wood interior while also providing a concealed location for the LED strip. The lighting is hidden behind the backrest, with additional lighting beneath the benches. Light is softly diffused through the wood structure and gaps, reducing the visual distraction of exposed LED points and creating a layered indirect lighting effect.
The LED system can be configured with colored lighting or warm white lighting and adjusted using a remote control, adding flexibility to the overall wellness atmosphere.
For OEM and ODM projects, the bench layout, backrest design, lighting position, lighting color, and control system can all be customized according to the product specification.

Integrated Open Shower Area

After a sauna session, users can move directly into the adjacent open shower area for rinsing.
The shower area uses waterproof materials such as aluminum composite panels to better withstand moisture and direct water exposure. Unlike the sauna area, where natural wood is the primary material, the shower area uses materials selected specifically for a wet environment.
Shower fixtures, installation methods, drainage, and other functional details can also be customized according to the project requirements.
For projects that need to combine sauna functionality with an indoor bathroom, Alphasauna can also develop bathroom sauna concepts based on the available space and layout.

Multi-Purpose Customizable Space

The right-side area uses a flexible multi-purpose layout and can be configured as a lounge, changing area, storage space, or private bathroom depending on the project requirements.
The interior can be divided into different functional zones, while frosted glass doors provide additional privacy without compromising the clean and open appearance of the overall design.
The specific layout, door style, and interior configuration can all be customized for different projects.

Large Glass Panels

Large glass panels make the sauna interior feel more open and visually connected to the surrounding environment.
Natural light can enter the space during the day, while the wood interior and LED lighting remain visible from outside. From inside the sauna, users can also enjoy views of the surrounding outdoor environment.
Glass dimensions, placement, and privacy options can be adjusted according to the project. For applications requiring greater privacy, options such as frosted or tinted glass can be considered.

Black Exterior Finish and Waterproof Roofing

The sauna structure is built with thermo pine. Natural wood is retained throughout the interior to create a warm sauna environment, while the exterior is finished in black.
The dark exterior provides an additional protective finish while giving the structure a clean, contemporary architectural appearance. The contrast between the black exterior and warm natural wood interior creates a combination of modern design and natural character.
Waterproof roofing: The roof uses a combination of a waterproof membrane and asphalt shingles. The waterproof membrane provides a base layer of protection, while the asphalt shingles create an additional exterior barrier against rain and changing outdoor weather conditions.

Alphasauna Custom Outdoor Sauna Combinations

Alphasauna offers multiple multi-zone sauna configurations that can combine a sauna with a cold plunge, shower, changing room, or lounge area.

Sauna + Cold Plunge

A combined hot and cold wellness layout with a dedicated area for cold plunge equipment and an integrated bench for relaxation. Users can move between the sauna and cold plunge within the same outdoor wellness setup.

Sauna + Shower

A two-zone configuration with a sauna on one side and a semi-open shower area on the other.
The shower area uses moisture-resistant, waterproof materials, while the shower fixtures and drainage layout can be customized according to the project requirements. The sauna can support both wood-burning and electric heating configurations, with a black exterior finish and panoramic glass.

Sauna + Changing Room or Lounge

A compact integrated sauna with the sauna cabin positioned at the front and a more private lounge or changing area at the rear. The rear section can include built-in seating and a tabletop for changing, relaxing, or other functions.
The curved barrel-style structure is designed to retain heat efficiently while eliminating the need for a separate auxiliary building. Wood species, cabin length, and other structural details can be customized according to the project.
