WHAT IS A SAUNA?
A sauna is a small cabin with four walls and a ceiling or roof. They are usually made from wood paneling and can be placed outdoors or indoors. The most popular types of sauna are traditional and infrared saunas. Saunas use a heater to raise the temperature inside the cabin to a very high level.
Traditional saunas typically run at 158°F to 212°F (70°C to 100°C) while infrared saunas are a little cooler at 110-130°F (45°C to 55°C). This intense heat has a therapeutic effect on the body and many people find the experience deeply relaxing. Saunas typically accommodate 1-6 people depending on cabin size. They can be enjoyed solo or in the company of friends.
WHAT IS A HOT TUB?
A hot tub is a large tub that looks a bit like a bath. The tub is filled with warm water with a temperature of 98°F to 104°F (37°C to 40°C). Water jets are used to create streams of water that massage the body while you relax in the warm water. Hot tubs can be placed indoors or outdoors but are usually used outdoors.
THE KEY DIFFERENCES
Let’s take a closer look at the key differences of a hot tub vs sauna.
TYPE OF HEAT
The main difference between a hot tub and a sauna is the type of heat used. A sauna uses a dry intense heat to warm the body and trigger an intense sweat. A hot tub uses wet heat. Warm water at a much lower temperature is used for heating effect.
MASSAGE
Hot tubs massage the body using powerful water jets. These water streams knead the body and help soothe sore muscles and relieve tension. Saunas do not have a massage capability. Unless you get a friend to rub you down while you bask in the intense heat.
INTENSE SWEAT
Saunas generate intense heat. Traditional saunas run at temperatures in the region of 158°F to 212°F and trigger a profound sweat. This has a cleansing effect on the skin and helps detox the body by flushing out toxins. Hot tubs run at a much lower 98°F to 104°F.
SOCIAL EXPERIENCE
Saunas and hot tubs are both great for sharing a social experience. Sharing a sauna or hot tub with friends or family is a great way to unwind, bond, and spend time together. Saunas have been used for centuries to bring communities together and promote physical and mental wellness.
MAINTENANCE
While both a sauna and hot tub require ongoing TLC, the maintenance requirements of a hot tub are much greater compared to a sauna. An outdoor sauna will require occasional inspection and wood treatment to ensure it stands up to the elements. They’re very easy to care for. Hot tubs on the other hand require frequent monitoring and cleaning.
The water should be periodically changed and the tub scrubbed down according to the manufacturer’s guidelines. Additionally, the water must be monitored for cleanliness, the water filters checked, cleaned, and replaced according to guidelines, and the tub should be covered when not in use.

INSTALLATION
What about installation? Saunas and hot tubs come with some basic installation considerations that need to be taken care of. Most saunas require an electrical connection. However, if you plan to use a wood-burning stove instead of an electrical heater – then you can forget about an electrical connection.
Hot tubs on the other hand require both an electrical and plumbing connection. Hot tubs are electrically powered and require water to operate. While some argue that you can use a hose pipe to fill a hot tub, it’s a lot easier if you get the device properly plugged into your home water system. Not only is it a breeze to fill it but you can drain it without any complications when it comes time to change the water.

PARTY TIME
When comes to enjoying some party time, a hot tub edges it over a sauna. If you’re enjoying a party with some friends and suggest everyone jumps in the hot tub you’re going to get high fives all around. If you suggest everyone jumps in the sauna for a quick sweat session you’re going to get some funny looks. Although they are both great for a shared social experience, a hot tub is a clear winner as party entertainment.
RELAXATION
Both sauna and hot tubs are excellent devices for relaxation. There’s very little to separate them in terms of relaxation. They are both incredibly effective at relieving stress and relaxing the mind. In fact, they are effective ways of relaxing both the mind AND body. Which is better? It comes down to personal preference. Do you prefer relaxing in a dry, hot environment, on a wooden bench? Or, in a tub surrounded by warm gushing water?
PRICE
There’s very little difference in price between a sauna and a hot tub. Both devices are available in a range of sizes and price points. A small, budget sauna will be much cheaper than a large deluxe hot tub and vice versa. There’s a sauna and hot tub out there to meet all budgets.
HEALTH BENEFITS OF SAUNA vs HOT TUB
The health benefits of sauna and hot tub largely overlap. They both heat the body and relax the mind. This has a therapeutic effect on the body and leads to several potential health benefits. Below we cover the key health benefits of sauna vs hot tub.
Health Benefits of Sauna

Health Benefits of Hot Tub
- Relaxation
Like a sauna, spending time in a hot tub is deeply relaxing. This is the single greatest health benefit for most people. Chilling out in a hot tub is a great way to unwind after a long stressful day. Even better, the experience can be shared with others.
- Boost Mental Health
Many people find spending time in a hot tub can help boost their mental health. The combined effects of relaxation and some quality ‘me time’ can really help improve mood and even lead to a better night’s sleep.
- Soothes Sore Muscles
Hot tubs are often used to massage and warm sore muscles. This may have the effect of reducing pain and loosening tight muscles.
- Relieves Joint Pain
Another potential health benefit of a hot tub is its ability to temporarily relieve joint pain. The combined effects of warm water and gushing jets may help reduce pain and inflammation.

ADVANTAGES OF SAUNA
What are the advantages of a sauna vs hot tub? If you’re still in two minds and can’t decide which is better for you – we’ve summed up the advantages of a sauna below.
Dry Heat
Saunas heat the body using dry heat. If you want a device with low humidity and don’t want to get wet – a sauna could be just what you’re looking for.
Greater Heat
Saunas get much hotter than hot tubs – especially traditional saunas. A traditional sauna runs at 158°F to 212°F while the water in a hot tub is heated to just 98°F to 104°F.
Intense Sweat
If it’s an intense sweat session you’re after, a sauna is what you need. A sauna will trigger a much more intense sweat thanks to the high-temperature environment.
Easy Maintenance
A sauna is easier to maintain. All you have to look after is the timber frame and the heating unit. In most cases, an annual check-up will be all the unit needs. On the other hand, a hot tub demands regular monitoring of the water, cleaning and replacing of filters, and periodic water changes.
Energy Efficiency
Saunas are more energy efficient than hot tubs – especially infrared saunas. Hot tubs consume more electricity to heat a large tub of water and keep it warm.
Year Round Use
Saunas can be used all year round and in all weather conditions – they have four walls and a roof. Hot tubs are weather dependent and can only be enjoyed during good weather.
Versatility
A sauna offers excellent versatility above and beyond a hot tub. While both can be sat in and used to relax and unwind – a sauna allows you to stand up, perform stretches, and even do yoga if the mood takes you.
ADVANTAGES OF HOT TUB
What are the advantages of a hot tub over a sauna? Need some more information? Below we run through the key benefits of a hot tub.
Warm Water
Hot tubs allow you to soak and unwind in a big bathtub. If you’re a fan of water and enjoy nothing better than relaxing in a wet humid environment – then a hot tub is a clear winner over the dry heat of a sauna.
Massage
Most hot tubs are equipped with water jets that create powerful streams that massage the body. This feels great on tired or sore muscles and takes your soak session to a whole other level. Saunas have nothing to offer in terms of massage – unless you bring a friend.
Moderate Heat
Hot tubs run at a much gentler level of heat compared to a sauna. If you are heat sensitive and dislike the oppressive heat of a sauna, then a hot tub may be just what you’re looking for. With a water temperature of just 98°F to 104° you can relax and unwind in a gentle comforting warmth.
Party Entertainment
Hot tubs are great for parties. ‘Hey, let’s jump in the hot tub’ sounds a lot better than ‘Hey, why don’t we all move into the sauna’. If you’re planning on having some friends over – the chances are they’re more likely to jump into a hot tub than a sauna.
