How to Choose the Best Indoor Sauna for Your Home

Choosing an indoor sauna is one of the best investments you can make in your health and wellbeing. But with so many options available—from portable units to custom-built installations—the decision can feel overwhelming. After helping hundreds of people select their perfect sauna over the past 15 years, I've developed a systematic approach that makes this process straightforward.

When making a comparison between different heating technologies, it's helpful to understand how various systems deliver therapeutic benefits. Many people find that comparing infrared versus traditional heating methods helps clarify which approach aligns better with their wellness objectives and tolerance for heat intensity.

In this guide, I'll walk you through every factor you need to consider, from space requirements to long-term costs, so you can make a confident, informed decision that you'll be happy with for years to come.

Step 1: Assess Your Space

Before falling in love with any particular sauna, you need to know what your space can accommodate. This is the foundation of your decision-making process.

Measure Your Available Space

Grab a tape measure and record the dimensions of your potential sauna location:

• Width: Measure the widest point
• Depth: Measure from front to back
• Height: Measure ceiling height
• Door clearance: Note which way doors can swing
• Obstacles: Identify windows, outlets, vents

Popular Sauna Locations

Based on my experience, here are the most common and practical locations for home saunas:

Master Bathroom

This is my top recommendation. You're already close to a shower, which is convenient for pre and post-sauna routines. The existing ventilation usually works well, and the flooring is already water-resistant.

Spare Bedroom

Perfect if you have an extra room. You can create a dedicated wellness space with room for towel storage, a small refrigerator for water, and even a meditation corner.

Basement

Great for temperature control and privacy. Just ensure proper ventilation and consider adding a dehumidifier to manage moisture levels.

Garage or Outbuilding

Works well if properly insulated and climate-controlled. However, this location requires more extensive electrical work and weatherproofing.

Step 2: Determine Your Budget

Let's talk real numbers. Understanding the full financial picture helps you make a sustainable choice.

Purchase Price Ranges

Installation and Setup Costs

Don't forget these additional expenses:

• Electrical work: $200-$1,500 depending on circuit requirements
• Flooring preparation: $100-$500 if needed
• Ventilation: $100-$400 for additional venting
• Delivery and assembly: $100-$500 depending on location
• Accessories: $50-$200 for thermometers, bucket, ladle, etc.

Operating Costs

Monthly expenses vary by sauna type:

• Infrared saunas: $10-$20/month (very efficient)
• Traditional electric: $20-$40/month
• Wood-burning: Variable, depends on wood prices

"Many people focus solely on purchase price and are surprised by installation costs. Budget for the complete project, not just the sauna itself. A $3,000 sauna might become a $4,500 project after electrical work and setup." - Industry best practice

Step 3: Choose Your Sauna Type

This is where personal preference meets practical considerations. Let's compare your main options.

Infrared Saunas

Best for: Heat-sensitive individuals, energy efficiency, low maintenance

Pros:

• Lower temperatures (120-140°F) feel gentler
• Faster heat-up time (15-20 minutes)
• Lower operating costs
• Simpler installation
• Deep-penetrating heat for muscle recovery

Cons:

• Less traditional sauna experience
• Can't add steam/water
• Some prefer higher heat of traditional saunas

Traditional Finnish Saunas

Best for: Authentic experience, higher heat lovers, customization

Pros:

• Authentic sauna experience
• Can pour water on hot rocks for steam (löyly)
• Higher temperatures (150-195°F)
• More customization options
• Classic aesthetic appeal

Cons:

• Longer heat-up time (30-45 minutes)

Steam Rooms

Best for: Humidity lovers, respiratory benefits, skin hydration

Pros:

• High humidity great for respiratory health
• Lower temperatures (110-120°F)
• Excellent for skin hydration

Cons:

• More complex installation
• Requires steam generator
• Higher maintenance needs
• Not as portable or flexible

Step 4: Select the Right Size

Size dramatically affects both your experience and your budget. Here's how to choose wisely:

One-Person Saunas (3x4 feet)

Ideal for:

• Solo use
• Limited space
• Tight budgets
• Quick heat-up needs

Considerations: While cost-effective and space-efficient, you won't be able to stretch out fully or share the experience. Some people feel claustrophobic in very small units.

Two-Person Saunas (4x5 feet)

Ideal for:

• Couples
• One person who wants more room
• Most homes
• Moderate budgets

Considerations: This is the "Goldilocks" size—not too big, not too small. It's the most popular choice for home installations. Check out our two-person sauna guide for more details.

Three to Four-Person Saunas (5x6+ feet)

Ideal for:

• Families
• Entertaining
• Those who want extra space
• Larger budgets

Considerations: These create a more social wellness experience but require significant space and higher operating costs. Make sure you'll actually use the extra capacity.

Step 5: Evaluate Essential Features

Not all features are created equal. Let's separate must-haves from nice-to-haves.

Must-Have Features

Quality Heaters

For infrared saunas, carbon heaters provide better heat distribution than ceramic. For traditional saunas, look for heaters with appropriate wattage for the cabin size (typically 6-8 kW for home units).

Solid Construction

Check wood thickness (at least 3/4 inch), quality of joints, and door sealing. Poor construction leads to heat loss and higher operating costs.

Reliable Controls

Digital controls with timer functions and temperature presets make operation easier and more consistent. Look for easy-to-read displays and intuitive interfaces.

Safety Certifications

Ensure your sauna has appropriate certifications (ETL, CE, or similar). This matters for insurance, resale value, and most importantly, your safety.

Nice-to-Have Features

• Chromotherapy lighting: Color therapy enhances relaxation
• Built-in sound systems: Bluetooth speakers for music or meditation
• Reading lights: Extra lighting for reading or journals
• Oxygen ionizers: Improved air quality
• App connectivity: Remote control and session tracking
• Ergonomic backrests: Enhanced comfort during longer sessions

Wood Selection

Wood choice affects durability, maintenance, and user experience:

Step 6: Consider Installation Requirements

Understanding installation requirements helps you budget accurately and avoid surprises.

Electrical Needs

According to the National Fire Protection Association, proper electrical installation is critical for safety:

• Small infrared saunas: Standard 120V, 15-20 amp circuit
• Larger infrared saunas: 240V, 20-30 amp dedicated circuit
• Traditional electric saunas: 240V, 30-60 amp dedicated circuit

Always hire a licensed electrician. DIY electrical work on saunas is dangerous and may void warranties.

Ventilation Requirements

Proper air circulation prevents moisture buildup and ensures comfort:

• Intake vent near floor (pulls in fresh air)
• Exhaust vent near ceiling (removes humid air)
• Gap under door for air circulation

Flooring Considerations

Your floor must be:

• Level and structurally sound
• Able to support 500-800 pounds
• Water-resistant (tile, vinyl, sealed concrete)
• Easy to clean

Step 7: Research Brands and Read Reviews

Not all sauna manufacturers are equal. Here's what to look for:

Red Flags to Avoid

• No safety certifications
• Extremely low prices that seem too good to be true
• Poor customer service or unresponsive support
• Limited warranty (should be at least 5 years for quality units)
• Thin wood construction (under 1/2 inch)
• No clear return policy

Green Flags to Look For

• Comprehensive warranties (5+ years on heating elements)
• Responsive customer support
• Detailed installation manuals and videos
• Replacement parts readily available
• Positive reviews from verified customers
• Company has been in business for several years

Questions to Ask Before Buying

1. What's included in the warranty and for how long?
2. Is installation included or can you recommend installers?
3. What are the exact electrical requirements?
4. Can I see specifications for wood thickness and quality?
5. What's your return policy if it doesn't fit or meet expectations?
6. Are replacement parts available and at what cost?
7. Do you offer any financing options?

Step 8: Think About Long-Term Use

Your sauna should fit your life not just today, but years from now.

Lifestyle Changes to Consider

• Family growth: Will you need more capacity in a few years?
• Health conditions: Are there medical factors that might change your needs?
• Moving plans: Is this sauna portable enough to take with you?
• Resale value: Does this increase your home's value?

Maintenance Commitment

Be realistic about maintenance:

• Low maintenance: Infrared saunas with minimal cleaning needs
• Moderate maintenance: Traditional electric saunas
• High maintenance: Wood-burning saunas, steam rooms

If you're not committed to regular cleaning and upkeep, choose a low-maintenance option. A neglected sauna becomes unsafe and unpleasant quickly.

Making Your Final Decision

You've done your research—now it's decision time. Here's my recommended process:

1. Narrow to 2-3 options that meet your space, budget, and feature requirements
2. Request detailed specs and talk to customer service for each
3. Check recent reviews from the last 6 months
4. Verify warranty terms and installation requirements
5. Calculate total project cost including all extras
6. Sleep on it for at least 24 hours before purchasing

Remember, the best sauna isn't always the most expensive or the one with the most features. It's the one that fits your space, meets your health goals, and fits comfortably in your budget while being something you'll actually use consistently.
