Designing a sauna well is not only about choosing a structure that looks beautiful in a photograph. It is about creating a space that feels right in daily life. The best sauna projects are shaped by the way the room will actually be used: how it sits on the property, how it transitions into the rest of the home, what kind of heat experience you want, what material atmosphere you prefer, and which details will make the room easier and more enjoyable to return to over time.
That is why the strongest sauna projects usually begin with a design process rather than with one isolated product decision. A sauna may seem simple from the outside, but the finished experience is shaped by a series of smaller choices that work together: model, cladding, colour, wood species, flooring, heater, shower, accessories, and the overall rhythm of the space.
One of the most useful parts of the Theraluxe process is that much of this can now be visualized before the build begins by designing your Sauna in 3D. It lets you explore the sauna from multiple angles, compare materials, adjust key features, and place the design into your own setting so you can understand how it will look before committing. This is a way to explore exterior finishes, adjust materials, customize key features, rotate the model, and place it in your own space. That makes the design phase much more practical and much more grounded.
Start with the right sauna model
Before thinking about finishes, it helps to begin with the broader structure. Theraluxe’s outdoor sauna collection now includes Vana, Kotelo, Teplo, Solara, Solara X, and Oro.
That lineup matters because each model supports a slightly different kind of experience. Some are better suited to a more compact backyard footprint. Some create a brighter, more open glass-forward experience. Others support a more integrated ritual with covered transition space, showering, or a combined sauna-and-plunge layout.
In simple terms, the collection can be read like this:
- Vana for a smaller footprint and a more compact outdoor sauna experience
- Kotelo for a refined personal sauna with a strong architectural identity
- Teplo for a light-filled, glass-forward outdoor sauna
- Solara for a more transitional outdoor experience with a stronger entry rhythm
- Solara X for a larger version of that concept with more capacity and flexibility
- Oro for a complete sauna, shower, and plunge retreat in one fully integrated layout
Oro is especially important to mention because it moves beyond being a standalone sauna and becomes a full wellness environment. It is a dual-zone retreat with a winterized shower and automated plunge, which makes it a very different design proposition from a standard hot-room-only build.
Exterior colours and cladding set the first impression
Once the model is clear, the next major decision is how the sauna should read from the outside.
Once the model is chosen, the next decision is how the sauna should feel from the outside.
The exterior colour options include:
- Black
- Charcoal Grey
- Metro Brown
- Sage Green
- Sierra Tan
- Warm White
That choice does more than change the look of the sauna. It shapes how the structure sits within the property as a whole. A black exterior creates a stronger architectural presence. Sage Green feels softer and more connected to the landscape. Sierra Tan and Warm White lean quieter and more residential. Metro Brown and Charcoal Grey sit somewhere in between, offering a grounded, modern finish that works well across a range of settings.
This is why exterior colour should not be treated as a purely decorative decision. The right finish helps the sauna feel considered from the beginning, as though it belongs to the space around it rather than being added later. When the sauna is part of a wider landscape or architectural vision, colour can be just as important as the form itself.
The 3D configurator is a helpful way to begin exploring those possibilities, but it is only a starting point. Beyond the visualized options, Theraluxe can also work with more tailored directions when a project calls for something more specific.
Interior paneling shapes the atmosphere of the sauna
If the exterior introduces the sauna to the property, the interior paneling defines how the room feels once the heat comes on. It is one of the most important decisions in the entire design because it influences not only the look of the space, but also its warmth, softness, character, and long-term comfort.
The interior paneling options include:
- Thermally Modified Spruce
- Hemlock
- Thermally Modified Hemlock
- Black Waxed Thermo Spruce
- Thermally Modified Radiata Pine
- Thermally Modified Aspen
- Thermally Modified Magnolia
- Clear Cedar
- Mixed Species
Each one brings a different quality to the room. Thermally modified spruce offers a strong balance of warmth, stability, and a classic sauna feel. Hemlock feels cleaner and quieter, which makes it especially appealing in more minimal interiors. Thermally modified hemlock carries that same calm visual language with a more performance-driven edge. Thermally modified aspen feels especially soft and refined. Thermally modified magnolia brings a subtler, more elevated warmth. Black waxed thermo spruce adds mood and contrast. Clear cedar keeps the traditional aromatic sauna identity that many people still love. Mixed species opens the door to a more layered and bespoke material composition.
This is also where thermal modification becomes especially important. A broader review, Thermal Modification of Wood-A Review explains why thermally modified wood continues to gain traction in more demanding environments, noting improvements in dimensional stability, moisture behaviour, and biological durability. That matters directly in a sauna, where repeated heat and humidity cycles place constant pressure on the materials inside the room.

Flooring changes more than people expect
Flooring is often treated as a secondary choice, but in a sauna it shapes the room more than many people expect. It affects how the space feels underfoot, how warm or grounded it reads, and whether the interior feels visually continuous or more layered and architectural.
The flooring options include:
- Thermally Modified Spruce
- Ceramic Stone
- Clear Cedar
- Thermo Ash
- Ipe
Each one changes the experience in a different way. A wood floor keeps the room warmer and more unified in mood. Ceramic stone introduces a stronger contrast and a cooler tactile counterpoint to the wood around it. Thermo ash adds a darker, more polished material presence. Ipe brings density and a more architectural hardwood character. Clear cedar keeps the room within a more classic North American sauna language.
There is also a practical side to this decision. Flooring in a sauna has to handle heat, moisture, regular use, and cleaning over time. A U.S. Forest Service summary, Thermally Modified Wood: Field Performance and Testing notes improved dimensional stability and lower moisture uptake among the material’s key advantages, which helps explain why thermally modified flooring options are so well suited to sauna design.
Heater selection is one of the most defining choices
If wood shapes the atmosphere of the room, the heater shapes the heat experience itself. It influences how the sauna performs, how the steam feels, and how the room reads visually once everything is in place.
The heater options include:
- Homecraft Revive
- Homecraft Apex
- Harvia Virta
- HUUM Cliff
- HUUM Hive
These are not interchangeable in feel or presence. Each one brings a different visual character and a different way of experiencing the room.
Homecraft Revive introduces a strong tower-heater direction with a more sculptural vertical form. Homecraft presents Revive as a floor-standing tower heater with a substantial rock capacity, which helps create a fuller steam experience and a stronger focal point within the room.
Homecraft Apex moves in a similarly performance-oriented direction, but with a different visual and structural expression.
Harvia Virta brings a different kind of presence. Harvia positions Virta as a durable electric heater suitable for both home and commercial settings, with easier maintenance and a long-established reputation for reliable performance.
HUUM Cliff and HUUM Hive lean more fully into the modern Nordic heater aesthetic. HUUM is especially known for exposed stone, generous stone capacity, and a steam experience that feels softer and longer-lasting. HIVE, in particular, is especially compelling in larger rooms or more communal layouts because of the amount of stone it can hold and the stronger visual presence it brings.
In practice, the right heater choice usually comes down to a few things:
- room size
- desired humidity and steam feel
- visual preference
- whether the heater should recede or act as a centerpiece
- how the heater integrates with benches and circulation
Shower options shape the transition out of heat
A sauna experience is never only about the hot room itself. The transition after heat matters just as much. That is why the shower choice carries more weight than it may seem at first.
The shower options include:
- No Shower
- Self Winterized Shower
- Winterized Shower
Each one creates a different level of integration.
No shower keeps the project simpler and may be the right fit when the property already has another rinsing or cooling option nearby. A self-winterized shower adds much more daily convenience while still requiring some seasonal care. A fully winterized shower supports a more complete four-season ritual and creates a stronger connection between heat, rinse, and recovery.
This is one reason Oro stands apart within the broader Theraluxe lineup. Rather than treating the sauna, shower, and plunge as separate elements, it brings them together as one integrated wellness environment. If the goal is a more complete contrast-therapy setup rather than a sauna alone, becomes especially relevant.
Additional interior options complete the experience
The smaller elements in a sauna often determine whether the room feels merely finished or fully considered.
The additional interior options include:
- Bucket and Ladle
- Robe Wall Hook
- Towel Storage
- Heater Guard
- Fiber Optic Starlight Ceiling
These are the kinds of upgrades that often matter more in daily use than people expect.
A bucket and ladle set strengthens the ritual side of the sauna experience. Robe wall hooks make transitions easier and more intuitive. Towel storage keeps the room tidier and visually more resolved. A heater guard affects how safely and comfortably the sauna can be used, especially in more compact layouts. A fibre optic starlight ceiling changes the atmosphere entirely, giving the room a softer, more immersive evening mood that feels very different from a more functional lighting setup.
These are not essential in every project, but they are meaningful. They are often the details that shift a sauna from feeling simply built to feeling genuinely lived in.
There are custom options beyond what the visualizer shows
This is worth saying clearly: the 3D visualizer is a strong design tool, but it is not the outer limit of the design conversation.
The visible options provide an excellent framework for model selection, material comparison, and finish direction. But Theraluxe also works with projects that go beyond the on-screen menu. That can include more bespoke combinations of materials, project-specific site responses, custom colour coordination, residential integrations, and commercial requirements that need a more tailored approach.
This is where Theraluxe’s wider pathways matter.
Both Residential Saunas and Commercial Saunas pages make it clear that Theraluxe is not limited to freestanding outdoor models alone. The design work also extends into indoor home saunas and commercial wellness spaces, where the project often needs to respond to a wider range of technical, architectural, and experiential considerations.
Design in 3D before you commit
One of the most valuable parts of the process is being able to see your choices take shape before the build begins.
The configurator allows you to:
- compare models
- explore exterior colours
- test interior wood directions
- review flooring and heater combinations
- visualize shower and accessory upgrades
- rotate the sauna from different angles
- place it in your own space
That is what makes the tool so useful. It turns customization into something visible. Instead of trying to imagine how separate choices may come together, you can begin to understand the scale, proportion, mood, and overall fit of the sauna in a much more practical way.
Final thoughts
Custom sauna design matters because the best sauna is rarely the one with the most options on paper. It is the one whose choices work together well. The model, cladding, colour, interior paneling, flooring, heater, shower, accessories, and transition space all contribute to the final experience.
What makes the Theraluxe process especially compelling is the balance between structure and flexibility. The lineup is broad enough to support very different types of sauna projects. The option set is refined enough to create materially distinct results. And the 3D process makes those decisions easier to understand before build, which usually leads to stronger choices and a more confident outcome.
If you are beginning the process, the best place to start is not with one isolated material sample. It is with the kind of experience you want to create, then using the 3D design process to see how those decisions begin to come together in real space.
