Introduction

This guide is designed specifically for UK homeowners weighing up their options between our indoor infrared saunas and outdoor garden saunas. Whether you have a spare room crying out for a wellness upgrade or a garden ready for a dedicated retreat, the right sauna depends on your space, lifestyle and budget.

• We offer two main categories: indoor infrared home saunas (ranging from compact 1-person cabins to spacious 4-person models) and outdoor garden saunas built as weather-resistant structures for year-round UK use. Each type has different space requirements, power needs and installation complexity.

• Infrared saunas heat faster and cost less to run because they warm your body directly at lower temperatures (around 45–60°C), rather than heating the entire air volume like a traditional sauna.

• Garden saunas create a more immersive retreat experience, functioning as a dedicated sauna building in your own garden that can become a genuine outdoor feature alongside patios, hot tubs or seating areas.

• Check out our downloadable brochures and professional installation services before buying to confirm exact dimensions, electrical requirements and realistic running costs for your chosen model.

The rest of this article walks through type, size, location, budget and installation step-by-step so you can confidently pick the right Insignia sauna for your home.

1. Decide What You Want From a Home Sauna

Before you start comparing cabin sizes or browsing product pages, it pays to step back and think about why you actually want a sauna in the first place. Your goals and lifestyle will determine whether a compact infrared unit tucked into a bathroom corner makes sense, or whether a larger garden sauna is worth the investment. Getting this right upfront saves you from buying something that gathers dust after the initial novelty wears off.

Common goals for home sauna owners

• Relaxation after work: A quick 20-minute sauna session can become a ritual to decompress from the day, offering deep relaxation without leaving the house.

• Recovery after training: Athletes and fitness enthusiasts use heat to support muscle recovery, improve circulation and reduce stiffness after exercise.

• Supporting cardiovascular health: Regular sauna bathing has been associated with improved blood flow and relaxation responses, though those with existing conditions should consult a doctor first.

• Family wellness: Some households want a shared space where partners or family members can enjoy sauna time together.

• Adding property value: A dedicated wellness space can increase the appeal of a modern UK property, particularly for buyers who prefer spa-like features at home.

How often will you realistically use it?

Be honest with yourself here. If you plan to use a sauna two to three times per week as part of a regular routine, investing in a permanent cabin makes sense. If you’re thinking occasional weekend use, a smaller 1-person infrared model might be more practical than committing to a large garden structure.

Who will use it most?

• Single user: A compact 1-person infrared sauna is usually sufficient and the most cost-effective choice.

• Couple: A 2-person cabin gives enough room to relax together without feeling cramped.

• Family of 3–4: Larger 3–4 person Insignia models or a garden sauna with generous bench space works better for social use.

Indoor spa corner or garden retreat?

Think about where this sauna fits into your home life. An indoor installation works well if you want quick access from your bathroom, bedroom or home gym. You step out of the shower, walk three metres, and you’re in your sauna. A garden sauna, on the other hand, creates separation from the house, a dedicated retreat where you can enjoy fresh air between sessions, perhaps paired with outdoor seating or a cold plunge.

At this stage, it’s worth browsing our brochures to find inspiration, dimension diagrams and lifestyle photography that can help you visualise both options.

2. Choose Between Infrared and Traditional-Style Garden Saunas

We focus on two main product types: advanced infrared saunas designed for indoor installation, and purpose-built garden saunas for outdoor use. These feel quite different in practice, so understanding the distinction helps you choose the right experience for your household.

How infrared saunas work

Insignia infrared saunas use modern infrared heaters, typically carbon panels integrated into the walls and backrests, to warm your body directly rather than superheating the air around you. This means the cabin reaches a comfortable temperature of around 45–60°C, significantly lower than the 70–85°C typical of a traditional sauna. The infrared heat penetrates superficial tissues, raising your body temperature and triggering heavy sweating without the intense “wall of heat” that some people find overwhelming.

How garden saunas differ

Outdoor garden saunas from Insignia are designed as dedicated sauna buildings with insulated walls, weather-resistant cladding and substantial glazing. They offer a more immersive experience, stepping outside, walking to your garden retreat, and settling into a spacious cabin with room to stretch out. Many models include options for traditional-style electric heaters, allowing higher temperatures and the option for a more classic sauna experience.

Comparing the two types

Heat-up time: Infrared cabins typically reach a usable temperature in 10–15 minutes. Garden saunas with traditional electric heaters may need 30–45 minutes to warm up fully, depending on size and insulation.

Temperature range: Infrared operates at 45–60°C; traditional-style garden saunas can reach 70–85°C for those who prefer more intense heat.

Energy usage: Infrared panels draw less power (often 1.5–3 kW total) and run for shorter preheat periods, making them cheaper per session. Larger garden saunas with 6–9 kW heaters consume more electricity.

Installation complexity: Indoor infrared cabins are modular, often connecting to a standard 13A socket. Garden saunas require site preparation (a solid base), armoured electrical cable run by a qualified electrician, and potentially more planning consideration.

Best location: Infrared suits spare rooms, bathrooms, garages or home gym corners. Garden saunas work best in established gardens with space for a base and electrical supply.

Which suits your home?

Many UK households in terraced houses, semi-detached properties or flats naturally lean toward indoor infrared cabins because of space constraints and simpler installation. Detached homes with moderate to large gardens might prefer the dedicated outdoor sauna experience, especially if there’s already a patio, decking or hot tub area that could become a complete wellness zone.

Some people simply prefer intense heat and the ritual of higher temperatures, while others find the gentler, deep-warming feel of infrared more comfortable for longer 20–30 minute sessions. Both are valid, it comes down to personal preference.

3. Indoor Infrared Saunas: Are They Right for Your Space?

Insignia’s indoor infrared saunas are designed with UK homes in mind. They’re engineered to fit into spare rooms, large bathrooms, converted garages or dedicated wellness corners without requiring major structural changes. If you don’t have outdoor space or simply prefer the convenience of stepping into a sauna without leaving the house, this is likely your best option.

Size range and power requirements

Typical Insignia infrared models range from compact 1-person cabins (suitable for tight spaces) up to family-friendly 3–4 person units with multiple bench positions. Smaller cabins usually require only a standard 13A electrical connection, the same plug you’d use for a kettle or a washing machine. Larger models may need a dedicated circuit, so it’s worth having an electrician confirm your consumer unit can handle the load before you order.

Measuring your space

Before you fall in love with a particular model, measure your target room carefully. Note the length, width and ceiling height, then compare these figures with the dimensions listed on the infrared sauna product pages. Remember to allow extra clearance for:

• The door swing (most cabins have outward-opening glass doors)

• Ventilation gaps recommended by the manufacturer

• Comfortable access to step in and out

Floor and surface considerations

Indoor saunas work best on moisture-resistant, level surfaces. Suitable floors include:

• Ceramic or porcelain tiles

• Vinyl or laminate flooring rated for moisture

• Concrete garage floors (with a protective mat if desired)

Avoid placing a sauna directly on deep-pile carpet. If carpet is your only option, consider laying a plywood base underneath to create a stable platform.

Common installation locations

• Master bedroom corner: Creates a private spa experience accessible from your ensuite

• Converted dressing room or box room: Ideal for unused space that’s otherwise wasted

• Home gym corner: Perfect for post-workout recovery, step off the treadmill and straight into the sauna

• Large family bathroom: Integrates wellness into your existing routine

• Garage: Plenty of floor space, and concrete floors handle heat and moisture well

Before making a final decision, download the specific brochures from our brochure page to review technical specs, wood types, heater layouts and control panel options for your shortlisted models.

Key Features to Look For in an Insignia Infrared Sauna

Not all infrared cabins are created equal. Even among similar-sized models, differences in heater quality, construction and features can significantly affect your sauna experience. Insignia includes premium features across its range, but it’s worth understanding what to look for.

Heater placement and coverage: Quality infrared saunas distribute carbon panels across multiple surfaces, walls, backrests, sometimes floor or calf areas, to ensure even heat coverage. Check how many panels are included and where they’re positioned.

Interior bench space vs exterior footprint: A cabin that measures 120cm wide externally won’t give you 120cm of internal bench space. Review internal dimensions to ensure there’s enough room to sit comfortably or recline without feeling cramped.

Glass door design: Clear tempered safety glass doors are standard on Insignia models, giving the cabin a modern, open feel. Consider whether you prefer clear glass or would opt for tinted/frosted options if available, particularly for bathroom installations.

Interior timber: Insignia typically uses light-coloured softwoods like hemlock, which stay cool to the touch at sauna temperatures and brighten the interior. Quality timber should be smooth, free of rough edges and properly sealed at joints.

Modern comfort features commonly found in Insignia saunas include:

• Interior LED lighting with brightness control

• Chromotherapy (colour-changing) lighting for mood setting

• Digital control panels for temperature and timer

• Bluetooth audio integration for music or podcasts

• Ergonomic backrests and headrests

Safety and compliance: Look for CE-marked components, overheat protection on heaters, and proper ventilation grills. The manual should include maximum recommended session lengths, typically 20–30 minutes for most users.

One of the major advantages of infrared is that Insignia designs its range to plug into UK homes without complex flues, chimney systems or heavy structural changes. There’s no wood burning, no steam generator plumbing and no specialist ventilation beyond the built-in grills.

4. Outdoor Garden Saunas: Turning Your Garden Into a Retreat

If you have the outdoor space and want more than just a cabin in the corner of a room, Insignia’s garden saunas offer something genuinely special. These are built as weather-resistant outdoor structures designed for year-round use in the UK climate, rain, frost and all.

Unlike indoor infrared models, garden saunas function as dedicated sauna buildings. They become a destination in your backyard: step outside, walk across the lawn or decking, and enter a self-contained wellness space. Many homeowners install them alongside hot tubs, outdoor seating areas or garden offices to create a complete outdoor living zone.

Planning and site considerations

Before ordering, check local planning rules. In England, Scotland, Wales and Northern Ireland, many small garden buildings fall under “permitted development” rights, meaning you don’t need formal planning permission. However, rules around height, distance from boundaries and total outbuildings coverage can apply. If your property is listed, in a conservation area or subject to restrictive covenants, additional checks are essential.

Site preparation

Garden saunas need a solid, level base capable of supporting several hundred kilograms (the structure plus occupants). Common options include:

• Concrete pad (poured specifically for the sauna)

• Paving slabs on a compacted base

• Composite decking rated for the weight

Drainage is important too, ensure rainwater flows away from the sauna base rather than pooling around it. Poor drainage leads to damp, rot and shortened lifespan.

Insulation and weather resistance

Insignia’s garden saunas are designed with insulated walls and roofs to handle UK weather conditions. Thicker wall construction, weather-resistant cladding and properly sealed doors and windows keep heat in and moisture out. This means the sauna performs well even in winter, maintaining internal temperatures without excessive energy loss.

Choosing the Best Size and Layout for Your Garden Sauna

Garden sauna footprints vary considerably, from compact 2-person cabins suited to smaller gardens up to larger 4–6 person social spaces that can host friends and family. Size affects not only the atmosphere and comfort but also cost, electrical requirements and foundation size.

For narrow terraced gardens: A compact 2-person cabin with a modest footprint (around 1.5m x 1.5m externally) can fit into surprisingly tight spaces. Position it at the end of the garden against a fence or wall.

For mid-sized lawns: A 3–4 person model gives more space for comfortable benches without overwhelming the garden. You’ll have room for an L-shaped bench layout or straight benches on opposite walls.

For larger rural plots: Consider a 4–6 person lodge-style sauna with a small porch or relaxation area. These become genuine outdoor rooms and work well for entertaining.

Layout considerations

• L-shaped benches vs straight benches: L-shaped layouts maximise seating in corner positions; straight benches offer simpler designs and easier cleaning.

• Full-height glazing vs smaller windows: Large panoramic windows create a bright, open feel and let you enjoy garden views. Smaller windows offer more privacy if neighbours overlook your garden.

• Orientation: If possible, position the panoramic window away from direct street view and towards the most attractive part of your garden, a flower bed, water feature or tree line.

5. Power, Installation and Using Insignia’s Professional Services

Even though many Insignia saunas are designed for straightforward installation, getting the power supply and assembly right is non-negotiable. A poorly installed sauna can be inefficient, uncomfortable or even unsafe.

Understanding power requirements

Smaller indoor infrared cabins (1–2 person) often run on 1.5–2.5 kW and can connect to a standard 13A household socket. This makes them genuine plug-and-play options for many UK homes.

Larger indoor infrared models and garden saunas may require a dedicated electrical circuit. This typically means a separate run from your consumer unit, correctly fused and protected by an RCD. For outdoor installations, an armoured (SWA) cable is usually required, run underground or along protective conduit to the garden structure.

Always have electrical work for 230–240V high-load appliances checked by a qualified electrician. You’ll find the specific kW rating, fuse size and wiring requirements in our product specifications and brochures.

Insignia’s professional installation services

If the idea of assembling a large glass-and-timber structure feels daunting, Insignia offers dedicated sauna installation services covering:

• Delivery to your property

• Carrying components to the installation location (indoors or garden)

• Full assembly of panels, doors and benches

• Connection of electrical components (in coordination with your electrician, where required)

• Functional testing and guidance on first use

• Removal of packaging materials

Advantages of professional installation

• Correct fitting: Installers familiar with Insignia’s modular systems ensure panels align properly, doors seal correctly and no gaps let heat escape.

• Faster completion: What might take a DIY novice a full weekend can be completed in half a day by experienced installers.

• Compliance confidence: Professional teams understand safe wiring practices, ventilation requirements and UK regulations.

• Aftercare guidance: Installers can walk you through the first heat-up cycle, control settings and basic maintenance.

Realistic timelines

From order to delivery, expect timelines to vary based on stock availability and your location. Installation itself typically completes within a day for indoor infrared cabins. Larger garden structures may take slightly longer, particularly if site preparation (base, electrical run) needs to happen first.

Where to Find Technical Details and Planning Information

Don’t guess about technical requirements. Insignia provides comprehensive documentation that answers most questions before you buy.

Official brochures: The brochures page includes downloadable PDFs with exploded diagrams, wiring notes and detailed dimensions in millimetres for most current sauna models. These documents are your primary source for technical accuracy.

Checking access routes: Before ordering, cross-check the sauna’s external dimensions (when flat-packed in delivery boxes or as assembled panels) against your doorways, stairs and corridors. There’s no point ordering a beautiful 4-person cabin if the panels won’t fit through your front door or up your staircase.

Personalised advice: If you’re unsure about siting, power requirements or whether a particular model fits your space, contact Insignia customer support. Sending photos and measurements often helps their team provide tailored recommendations before you commit.

6. Budget, Running Costs and Long-Term Value

A home sauna is an investment, but it’s one that can pay for itself over time, particularly if you’re currently spending money on gym memberships, spa days or wellness retreats.

Price guidance

• Compact 1–2 person indoor infrared cabins: Entry-level investment, lowest upfront and running costs

• Larger 3–4 person indoor infrared models: Mid-range, higher capacity, but still reasonable energy use

• Garden saunas: Higher investment due to construction, insulation and weatherproofing, plus potential groundworks

7. Design, Comfort and Extra Features to Consider

Once you’ve decided on type, size and budget, the aesthetics and comfort features make the difference between a sauna that’s merely functional and one that feels genuinely luxurious.

Interior timber choices

We typically use pale softwoods like hemlock for interior panelling and benches. Light-coloured timber keeps the cabin bright, reflects LED lighting effectively and remains comfortable to sit on at higher temperatures. Quality timber should be smooth to the touch, properly jointed and free of splinters or rough edges.

Glass, light and ambience

• Glass doors: Clear tempered safety glass is standard, creating an open, modern aesthetic. Tinted options provide more privacy.

• Side windows (garden saunas): Large panoramic windows let in natural light and garden views; smaller windows suit more private setups.

• LED lighting: Integrated ceiling or wall-mounted LEDs with dimmer control allow you to set the mood, bright for reading, dimmed for relaxation.

• Chromotherapy: Colour-changing lighting cycles through different hues, often marketed for mood enhancement. Whether you believe in colour therapy or just enjoy the visual variety, it adds a touch of luxury.

Comfort extras

• Headrests and backrests (often ergonomically curved)

• Smooth bench edges that don’t dig into legs

• Towel hooks and small shelving for water bottles

• Aromatherapy dishes for essential oils (check model compatibility)

Entertainment and controls

Many Insignia saunas include:

• Bluetooth speakers: Stream music, podcasts or meditation tracks from your phone

• FM radio: Built into the control unit

• Digital control panels: Set exact temperature and session timer from inside the cabin

• Remote or app control: Some newer models allow preheating from your phone (check specific product specs)

For visual inspiration, browse the lifestyle photography in our brochures and product pages. Seeing how other installations look can help you visualise the sauna alongside your existing bathroom or garden décor.

8. Safety, Maintenance and Daily Use Tips

Correct use and simple maintenance keep an Insignia sauna safe, hygienic and pleasant for years. Most of this is common sense, but it’s worth reviewing the basics before your first session.

Basic safety practices

• Start with shorter sessions: Limit yourself to 15–20 minutes initially, especially if you’re new to sauna bathing. Increase duration gradually as your body adapts.

• Stay hydrated: Drink water before, during and after your session. Sweating heavily depletes fluids.

• Exit if you feel unwell: Dizziness, nausea or an unusually rapid heartbeat are signals to leave immediately. Cool down gradually.

• Avoid alcohol: Using a sauna while intoxicated increases the risk of dehydration, fainting and accidents.

Who should consult a doctor first

Certain people should get medical advice before starting regular sauna use:

• Those with uncontrolled high blood pressure or unstable heart conditions

• People with implanted medical devices (pacemakers, insulin pumps)

• Pregnant women (especially in early pregnancy)

• Anyone taking medications that affect sweating or heart rate

Simple maintenance routines

• Wipe benches and backrests after each use: A simple towel wipe removes sweat and prevents staining.

• Leave the door open after sessions: This allows the interior to air dry and prevents musty smells.

• Clean glass and controls periodically: Use non-abrasive products and a soft cloth.

• Check ventilation grills: Ensure they’re not blocked by towels or debris.

• Follow manual guidance: Insignia manuals include specific maintenance instructions for each model.

Long-term care for garden saunas

Outdoor structures face more wear from weather exposure:

• Inspect exterior panels, roof coverings and seals annually

• Reapply protective timber treatments as recommended (usually every 1–2 years)

• Check that drainage around the base is working and water isn’t pooling

• Clear leaves and debris from the roof and guttering

Integrating sauna into your routine

The most successful home sauna owners build it into regular habits:

• Post-workout ritual: Use the sauna after evening exercise for recovery

• End-of-day wind-down: A 20-minute session before bed supports relaxation

• Weekend family time: Create a Sunday “spa hour” tradition with the household

• Pair with contrast therapy: Follow your sauna session with a cool shower for an invigorating finish

Frequently Asked Questions

Can I put an Insignia infrared sauna in a flat or apartment?

Yes, many compact infrared models are suitable for flats, provided you have adequate floor space and electrical capacity. Check that your circuit can handle the load (most 1–2 person units run on a standard 13A socket). Ventilation is important, use the sauna in a room with some airflow or open a window afterwards to manage humidity. If you’re a leaseholder, confirm with your freeholder or management company that installing a sauna doesn’t breach your lease terms.

How long does an Insignia sauna typically last?

With regular cleaning and proper maintenance, a well-built infrared or garden sauna should last 10–15 years or more. The heating elements have finite lifespans (often rated for thousands of hours), but replacement parts are usually available. Garden saunas may require more exterior maintenance, timber treatments, seal checks and roof inspections to achieve maximum lifespan in the UK climate.

Can I move my sauna if I relocate?

Indoor infrared cabins are modular by design, so disassembly and reassembly are feasible if you’re moving house. Keep the original assembly instructions and hardware. Garden saunas are more challenging to relocate due to their size, weight and the need for a new prepared base at your destination. If you’re likely to move within a few years, factor this into your decision, a portable indoor model may be the safer choice.

Where can I see detailed specifications before I buy?

Visit our saunas page to browse current models, then download the relevant PDFs from the brochures section for full technical specifications, dimensions, wiring requirements and feature lists. These documents are updated for current model years and provide the most accurate information for planning your purchase.
