Torn between sweating it out in a sauna or floating in a fizzing tub like a stress-free marshmallow?
Here’s the quick take: hot tubs win for everyday comfort, joint relief, and all-around bliss; especially if you go for an acrylic model, a rustic wooden tub, or a sturdy rotomoulded option.
But don’t count saunas out just yet. They’re dry, toasty powerhouses for heart health and detox.
Curious which suits your life best? Let’s dive into the details and help you make your dream home spa a reality.
A sauna is like stepping into a warm wooden cabin built just for your sweat glands.
Traditional saunas heat the air using electric heaters or hot stones. The temperature? A fiery 70 to 100°C.
Infrared saunas are a little different. Instead of blasting hot air, they use infrared panels to warm your body directly. That means less air heat but just as much sweat.
Both types kick your heart rate up and leave you drenched in a detoxifying glow.
Hot tubs are all about soaking your cares away.
Water is heated to around 37–40°C, then comes the magic, hydrotherapy jets. They massage your muscles while you’re gently suspended in water.
Whether you’re unwinding in a sleek acrylic spa, hopping into a rugged rotomoulded tub, or enjoying the charm of a classic wooden one, the experience is soothing, immersive, and deeply relaxing.
Saunas turn your body into a calorie-burning, circulation-boosting machine.
That deep, dry heat makes you sweat, hard. This isn’t just a detox trend; it mimics a cardio workout by raising your heart rate and increasing blood flow.
Studies even suggest regular sauna use can lower blood pressure and reduce the risk of heart disease.
It’s like going for a brisk walk, without leaving the room. Oh, and mentally? That quiet heat feels like a reset button.
If your muscles are aching, the hot tub's your best friend.
The water lifts your body, taking the pressure off joints. Add jets, and you’ve got a warm massage that melts away stiffness, whether it’s post-workout pain or arthritis flaring up.
Hot tubs also help you wind down before bed. A 20-minute soak can improve sleep quality, no sleep apps required.
Both options help you hit the brakes on stress.
They improve circulation, reduce cortisol levels (your stress hormone), and give your mind some breathing room.
In short, sauna or tub, you’ll come out feeling like you’ve just returned from holiday.
Saunas work from the inside out. They use dry heat to raise your core temperature and trigger a deep sweat. It’s intense, but powerful.
Hot tubs, meanwhile, soothe from the outside in. The warm water and buoyancy ease pressure on joints while jets physically work your muscles.
One’s like cardio for your organs, the other’s physical therapy for your body.
Imagine sitting in a log cabin with the heat steadily climbing, sweat pouring, and your thoughts slowly quieting. That’s a sauna. It’s hot. It’s dry. And oddly satisfying.
Now picture sliding into warm bubbling water. Muscles relax. Jets knead your back. You’re basically soup, happy, relaxed, human soup.
Hot tubs are the life of the party. Great for chats, drinks, and relaxing with friends.
Saunas? More like a group meditation. You sit, sweat, maybe whisper. Social, sure. But it’s the quiet kind.
So if you're planning hot tub wine nights vs solo sauna zen time, your choice is clear.
Saunas are hot, really hot. Most people stay in for 10 to 20 minutes at 70–100°C. That’s enough to sweat it out and feel refreshed.
Hot tubs are milder, staying around 37–40°C. You can comfortably soak for 15–30 minutes without turning into a raisin.
Hot tubs often win the ‘stay-and-linger’ game.
Saunas are surprisingly flexible. You can install one indoors or outdoors.
Infrared saunas plug into a standard socket, while traditional ones might need a dedicated circuit. Just make sure the space is dry and well-ventilated.
Sizes vary, some are small enough for a bathroom corner, others fit the whole family.
Hot tubs, especially the larger acrylic or rotomoulded types, need a bit more prep.
They’re usually installed outdoors on a level, sturdy surface like decking or concrete. You’ll need water access, proper drainage, and a dedicated power supply.
Wooden tubs may have simpler needs, but heating and water care still matter.
Saunas generally need less room, around 2–3 square metres.
Hot tubs require 4–6 square metres or more, plus clearance around them for maintenance.
If you’re tight on space, a sauna is your compact wellness retreat. If you've got the garden space, the hot tub's ready to shine.
Here’s a ballpark:
Hot tubs usually cost more upfront, especially high-spec acrylic models. Wooden tubs and rotomoulded options may offer more value for money depending on features.
Saunas heat quickly and only when in use. They’re cheaper to run, around £20–£40 a month.
Hot tubs keep water warm constantly, which uses more power. Expect £40–£80 monthly, depending on insulation and frequency of use.
Hot tubs need ongoing care. You’ll be changing the water, balancing chemicals, cleaning filters, and more.
Budget around £150–£300 annually for supplies.
Saunas skip all this, you just wipe them down now and then.
Saunas are low effort.
Wipe the benches after use. Check the heater now and then. That’s mostly it.
Infrared models are even easier, no stones, no water, just simple upkeep.
Hot tubs are more high-maintenance.
You’ll need to test water regularly, add chemicals, clean filters, and drain and refill every few months.
It takes more time, but the reward is bubbly perfection every time you soak.
