Find the Sauna Kit That Fits Your Vibe

Each sauna kit includes the components needed to assemble the sauna structure, such as the walls, roof, benches, door, hardware, and other model-specific parts. Depending on the sauna you choose, the heater, controls, sauna stones, lighting, and accessories may also be included or available as optional upgrades.

Because every sauna model is different, we recommend reviewing the "What's Included" section on the individual product page before ordering.

Site preparation, foundations, electrical work, permits, assembly labor, and any special equipment needed to move or place the sauna are not included unless specifically stated.

Not sure what you'll need? Contact NW Immersion before ordering and we'll help you understand exactly what is included and what you should plan for before delivery.

Before your sauna arrives, make sure you have a level, stable installation area, adequate delivery access, and a plan for any required electrical work.

Site requirements vary by sauna model, so review the product-specific installation instructions before preparing a foundation or base. Depending on the sauna, this may include a concrete pad, paver base, deck, or another properly supported and level surface.

You should also confirm that there is enough clearance around the sauna, that the delivery path is accessible, and that your electrician has the heater specifications if electrical work is required.

We recommend checking local building, electrical, and HOA requirements before installation, as permits and code requirements vary by location.

If you're unsure whether your site is ready, contact NW Immersion before delivery and we'll help you review the requirements for your specific sauna.

The required surface depends on whether your sauna is installed indoors or outdoors, as well as the specific sauna model.

For outdoor saunas, the sauna should be installed on a stable, level, properly supported base. Depending on the model and site, this may be a concrete pad, paver base, deck, or another suitable foundation that can support the sauna and keep it level.

Most indoor sauna kits include their own floor and can be installed over many common finished flooring surfaces, provided the floor is level, stable, and appropriate for the space.

Some indoor sauna models do not include a built-in floor. For example, Leil Como indoor saunas are designed to sit directly on the existing floor and should be installed on a waterproof surface such as tile or another suitable moisture-resistant flooring.

Because foundation and flooring requirements vary by model, always review the installation requirements for the specific sauna you are purchasing before preparing the space. If you're unsure, contact NW Immersion and we'll help you determine the best setup for your sauna.

Electrical requirements vary based on the sauna heater, sauna size, and installation location. Most traditional electric sauna heaters require a dedicated 240V circuit, but the required amperage, breaker size, wire size, and control setup depend on the specific heater model.

Before any electrical work begins, provide your electrician with the heater's installation manual and electrical specifications so they can plan the correct circuit and installation. These are located in the Resources & Guides section of the product page.

Indoor and outdoor installations may also have different code requirements, including requirements for conduit, disconnects, GFCI protection, and equipment placement. All electrical work should be completed by a qualified electrician in accordance with the heater manufacturer's instructions and applicable local electrical codes.

We recommend selecting your sauna and heater before scheduling electrical work so your electrician has the exact specifications needed for your installation.

We recommend choosing your sauna and heater first, reviewing the electrical specifications, and discussing the project with your electrician before installation. Final heater installation is typically completed after the sauna structure is assembled and ready for the heater.

Do not schedule the final electrical installation until you have received and verified all heater-related components.

Many sauna kits are designed so they can be assembled by a homeowner with basic tools and general construction experience. However, the difficulty and time required vary depending on the sauna model, size, and design.

Some smaller modular saunas are relatively straightforward to assemble, while larger cabin-style saunas or models with more complex roofing, glazing, or interior components may be better suited for a carpenter, contractor, or experienced handyman.

We recommend having at least two people available for assembly and reviewing the installation manual before delivery so you understand the tools, site requirements, and steps involved.

If you would prefer to hire someone for assembly and don't already have a local contractor, Thumbtack.com can be a helpful resource for finding experienced handymen, carpenters, and assembly professionals in your area. We recommend sharing the sauna installation manual with any potential installer ahead of time so they can review the project and provide an accurate estimate.

Electrical work, including final heater wiring and connection, should be completed by a qualified electrician in accordance with the heater manufacturer's instructions and applicable local electrical codes.

If you're unsure whether a particular sauna is a good DIY project, contact NW Immersion and we'll help you understand the installation requirements before you order. For a simpler DIY-friendly starting point, you can also explore Golden Designs saunas.

Assembly time varies depending on the sauna model, size, site conditions, and the experience level of the person doing the installation.

Smaller modular sauna kits may be assembled in several hours, while larger cabin-style saunas or models with more complex roofing, glazing, or interior components may take a full day or longer. Site preparation, weather, access, and the number of people helping can also affect the overall installation time.

We recommend reviewing the installation manual before your sauna arrives and having at least two people available for assembly. If you are hiring a contractor, carpenter, or handyman, share the installation manual with them in advance so they can better estimate the time and labor required.

Electrical installation is typically completed separately by a qualified electrician after the sauna structure and heater location are ready.

Most sauna kits are delivered by freight carrier and arrive crated or palletized as curbside delivery.

Before delivery, make sure the delivery location is accessible for a large freight truck and that you have a plan for moving the sauna components from the delivery point to the installation area. Depending on the size and weight of the shipment, you may need additional people, a pallet jack, forklift, or other equipment to move the sauna safely.

When your sauna arrives, inspect the shipment before assembly. Take photos of the packaging and note any visible freight damage. We also recommend checking the components against the packing list as soon as possible so any missing or damaged parts can be identified before installation begins.

Whenever possible, verify all heater-related components, controls, stones, hardware, and accessories before scheduling your final electrical installation.

If anything appears damaged or missing, contact support@nwimmersion.com as soon as possible with photos and your order information. We'll work with you and the manufacturer to help resolve the issue and keep your installation moving forward.

Permit requirements vary depending on your location, whether the sauna is installed indoors or outdoors, and the type of work involved.

Some jurisdictions may require a building permit for an outdoor sauna or for modifications to an existing structure. Electrical work for a sauna heater may also require a separate electrical permit and inspection. Local building and electrical codes are enforced by the authority having jurisdiction, so requirements can differ from one city or county to another.

Before preparing your site or beginning installation, we recommend checking with your local building department and, if applicable, your HOA to confirm any permit, setback, zoning, or electrical requirements for your property.

Your electrician or contractor can also help determine which permits are required for their portion of the installation.

Because requirements vary by location, NW Immersion cannot determine permitting requirements for every property, but sauna dimensions, heater specifications, installation manuals, and other product information you may need for the permitting process are available on each product page.

If your sauna shipment arrives with visible damage or you discover that a part is missing, contact NW Immersion as soon as possible so we can help get the issue resolved.

Please take clear photos of any visible freight damage, the packaging, shipping labels, and the affected components. If a part is missing, let us know which item is missing and include photos of the parts you did receive whenever possible. Email the details to support@nwimmersion.com, along with your name and order information. Our team will work with you and the manufacturer to identify what is needed and coordinate replacement parts or the appropriate next steps.

We recommend inspecting your shipment and inventorying the components against the packing list before beginning assembly or scheduling final electrical work. Identifying an issue early helps us resolve it as quickly as possible and minimize delays to your installation.

Our goal is to make the process as smooth as possible and help keep your sauna project moving forward.
