Elevate Your Wellness Regimen and Buy a 4-Person Sauna!

A four-person sauna gives you ample room for a partner, a few friends, or a couple of family members to sit comfortably inside the space and enjoy all that a sauna has to offer - without anyone feeling cramped. 

You also get a lot more options when you buy a 4-person sauna: two-tier seating, full glass fronts, and enough interior volume to do some stretching inside the unit while you work up a solid sweat.

You’ll find everything from traditional cabins with thermo-spruce exteriors to hybrids that combine infrared, steam and red light therapy in a single structure. Every unit at SaunaKits.com ships with a full warranty and comes with world-class customer service long after the sale.

Wood Species

Your sauna’s wood influences how it looks, smells, and performs over the years. It matters more for a 4-person outdoor sauna that will be subjected to harsh elements over the years, such as rain, snow, UV light, and insects. You should make sure the sauna has either cedar or thermally modified wood in these cases. 

You have more flexibility for an indoor sauna that won’t be subjected to weather or insects. You can save money by going with a more affordable wood species.

Barrel vs Cabin Saunas

A barrel sauna is the classic style. It’s mostly used outdoors, and it looks absolutely stunning on a property. But style aside, the shape of these saunas encourages more efficient heating since the warmth keeps circulating round and round. Moisture and leaves naturally shed off the roof.

A cabin-style sauna makes more sense for inside your home, and it can work just as well outdoors. These structures are taller and tend to have more compact footprints for a four-person sauna. 

Choosing the Right Heating Method

A 4-person traditional sauna is powered by an electric heater in most cases, or in rustic setups and off-grid installations, a wood-burning heater. This is the original form of sauna therapy, and one that allows you to pour water over hot stones to add steam to the experience. It’s a really hot, radiating type of warmth.

A 4-person infrared sauna uses carbon or ceramic panels to warm your body directly at lower ambient temperatures. It’s a deeper, more penetrating type of heat. These saunas feel a little more comfortable, and they tend to cost less upfront and over time.

There are also 4-person hybrid saunas if you don’t want to choose! These are the best of both worlds. You can run one heater at a time or use them simultaneously for a more layered experience. 

Installing Your New Sauna for 4 People

Our team is here to help you navigate every step of your sauna journey. Not just when you buy a 4-person sauna, but long after the fact. 

Level Installation

All of the 4-person saunas for sale need a flat, level base - ideally concrete. But pavers work too. Decomposed granite (DG) can work as well. 

Just know a sauna of this size can weigh up to 700 pounds when fully assembled, and there can be another 300-500 pounds inside it when you’re using it with loved ones. So, don’t install it somewhere that can’t support that weight.

We can’t emphasize the importance of flatness enough. Even just a slight slope can cause the door to hang crooked and create gaps in the seal, letting heat leak out. 

Electrical Work

Most four-person saunas need a 240V circuit. So, plan on hiring an electrician to help you assemble the sauna and ensure everything is wired correctly. Some infrared-only models might just plug into a 120V outlet.

Frequently Asked Questions

What does a 4-person sauna cost?

Prices start at $5,990 and can exceed $8,000 depending on the brand, wood, and other features. Many models don’t include the sauna heater in the price, so budget for that as well. We let you use HSA/FSA funds to buy your sauna, and we have hassle-free financing options as well. 

What is a good size sauna for 4 people?

You want at least 70 inches of width and 55 inches of depth. That’s enough room for four adults to sit across two bench tiers without being on top of one another. 

How much does it cost to run a 4-person sauna?

That depends more on the heater you pair with your four person sauna than anything else. Most of the models in this collection will pair with a 4.5 kW heater, and running that for an hour can translate to around $2. They’re quite energy efficient! 

Where can I install a four-person sauna?

Indoors or outdoors. The backyard, basement, garage, or potentially a spare bedroom in your home. There are many options, and our customer service team can help you make the right choice. 

How much space do I need to install a sauna for four people?

Plan for around 7 feet x 6 feet, with a few inches of clearance on all sides. Usually around 8 feet of head height. 

What size heater goes with a sauna for four people?

Anything between 4.5 kW to 8 kW. It depends on how much interior space your sauna actually has and how fast you want to heat the sauna. 

What type of wood do I need for an outdoor sauna?

Cedar or thermally modified wood. These are better equipped to cope with harsh outdoor elements like UV, rain, snow, and insects. 

Is a barrel or cabin-style sauna better?

Only you can decide that! Both have their pros and cons. We love the way a four-person barrel sauna looks outdoors, though. Get a personalized recommendation from our team and we’ll recommend one of our 4-person saunas for sale!
