Sauna Kit: A Prefab Backyard Sauna, Ready to Install
Unlike sauna kits DIY buyers piece together themselves, our sauna kit is a factory-built structure — we help with the sale, the permit process, and the installation in your backyard.
Sauna Kits
What Is a Sauna Kit — and How Is It Different from a Sauna Tent or Pod?
A sauna kit is a factory-built structure. When you buy through HomeWiP, we handle the sale, the permit process, and the installation — it isn't a self-assembly box, and it isn't a from-scratch build you piece together on your own.
That also sets it apart from a fold-up infrared pod or a fabric sauna tent. An outdoor sauna kit is permanent — it stays on the property, holds true sauna heat, and is built to the same standard as any other backyard accessory structure.
Outdoor Living
Why an Outdoor Sauna?
HomeWiP's sauna line is outdoor-only. Indoor sauna conversions exist elsewhere, but a standalone backyard unit has real advantages.
No Moisture in Your Home
A standalone outdoor sauna keeps steam and humidity out of your house entirely — no moisture migration into living space.
Wood-Fired Heat, If You Want It
Being outdoors opens up the wood-fired heater option (pending city permits), which isn't practical for most indoor installs.
A True Retreat
Stepping outside to a separate structure makes the sauna feel like an actual retreat, not just another room.
Backyard Wellness features
Cute Sauna Spaces with Easy Installation, No Crane Required
Perfect for small backyards, patios, or cabins while offering fast heat-up times and authentic Scandinavian performance.
Mini Sauna
A small premium sauna designed for terraces, patios, and tiny outdoor spaces—delivering authentic sauna heat in a very compact form. Thermo spruce construction for excellent heat distribution. Black diamond shingles for durability.
Barrel Sauna
Constructed from thick thermo spruce staves, this sauna offers excellent insulation, moisture resistance, and decades of durability. Its traditional round shape reduces warm-up time and ensures even heat distribution, creating a powerful and relaxing sauna environment.
Tube Sauna with Terrace
A stylish 4-person outdoor sauna featuring a front terrace for cooling off between sessions - it combines modern aesthetics with excellent heat performance. The small terrace adds comfort and visual appeal while creating a relaxing outdoor experience.
Tube Sauna with Front Room
This sauna with built-in changing/first room provides exceptional comfort with a two-room layout that enhances usability and heat retention during cold months. Its sleek tube profile offers a modern appearance while maintaining efficient thermal performance.

Full Service
What's Included When You Buy a Modular Sauna From HomeWiP?
This is the core of what makes HomeWiP different. We manage the full cycle: the sale, the permitting, and the installation — sourced from the US-based factory partner behind HomeWiP's other accessory modular structures.
Compare that to a fully custom build: sourcing lumber, sizing a heater, framing, insulating, benching, and filing sauna plans and permits entirely on your own. A sauna is a backyard accessory structure HomeWiP already knows how to permit and install. You just Bara Badu Bastu.
Sizes
Which Sauna Kit Size Is Right for You?
All four modular models come from the same Sweaty Yeti line — pick the size that matches your household and how you plan to use it.
Sauna
The most compact modular footprint in the line at 48 sq ft (8′ × 9′) — a 6-person sauna well suited to a couple or small family.
Fit Plus
A 116 sq ft (8′ × 17′) fitness studio add-on for households that want a workout space alongside their sauna.
Sauna Fit
A 116 sq ft (8′ × 17′) sauna room paired with a dedicated workout room — sauna plus fitness in one structure.
Sauna Plus
The largest capacity in the line at 116 sq ft (8′ × 17′) — a 12-person sauna built for entertaining.
Heater Options
What Heater Options Are Available?
Every sauna ships with a heater choice — pick the one that matches how you plan to use it. Wood-fired for ritual and off-grid independence. Electric for convenience and consistency. Infrared for gentler everyday heat.
Wood-Fired
The traditional, off-grid option — authentic ritual and radiant heat, independent of electrical capacity. A sauna wood stove is the classic backyard-sauna experience; the trade-off is chimney planning and wood storage.
Electric
Push-button convenience with fast, consistent heat and the lowest day-to-day effort. A sauna electric heater needs its own dedicated electrical circuit, which is the main trade-off.
Infrared
Gentler heat at lower ambient temperatures — often the most comfortable choice for longer or more frequent sessions. It's a different, lower-humidity experience than a traditional dry or wood-fired sauna.
Permits
Do You Need a Permit for a Backyard Sauna?
In most jurisdictions, a sauna this size is a permitted accessory structure — the same category as any accessory structure (think garage or a bigger shed).
HomeWiP handles that process directly as part of the full-service purchase, rather than leaving you to navigate it alone.

A sauna kit is a permanent, factory-built modular structure that stays on your property and holds true sauna heat. A sauna pod or fabric sauna tent is a fold-up, temporary unit — a different category of product.
Wood-fired suits buyers who want ritual and off-grid independence. We will need to check with your city or County if they allow wood-burning options. Electric is the most convenient and consistent for regular use. Infrared offers gentler heat that's comfortable for longer sessions.
