Your guide to premium outdoor heated hot tubs
  • How to Select the Perfect Outdoor Hot Tub for Your Deck or Country House?
1 Size and Shape of the Tub
First, decide how many people will use the tub at the same time:
A compact round tub is perfect for 2 people
For families or groups — choose a 4–6 person model with wide seats
It's important to consider the size of your patio, terrace, or garden: the tub should fit naturally into the space without overwhelming it.
2 Bowl and Finish Material
Quality materials = durability and insulation.
• Acrylic and ABS plastic — for premium models
• Thermowood — for a Scandinavian or eco-style look
• Composite materials — for a balance between price and design
Make sure the inner bowl is UV-resistant, non-slip, and scratch-resistant.
3 Heating Type
You’ll need heating in winter. Available options:
• Electric — easy to connect but consumes more power
• Wood-fired — offers atmosphere and autonomy
• Hybrid — combines both for optimal control
4 Hydromassage and Air Massage
Look for models with multiple massage modes:
Water jets for back and legs
Air massage — gentle and relaxing
• Integrated lighting system — for a cozy evening ambiance
5 Installation and Maintenance
Make sure that:
Installation is possible on your site (flat surface, access to water and electricity)
The package includes filters, drain, and protective cover
Warranty and post-warranty service are available

  • 5 mistakes when buying an outdoor heated hot tub
1 No thermal insulation
Many people choose a cheaper model but forget to check if it has an insulated shell and cover.
Without insulation, the tub loses heat too quickly — and you'll spend twice as much on heating.
2 No filtration or disinfection system
If there's no filter or cleaning system, the water will go bad fast.
The tub turns into a hassle — you'll need to drain and clean it often by hand
3 Wrong size
1600 liters is the ideal volume for a family or group of up to 4 people.
Smaller = cramped, larger = overpaying for water and heating. The wrong size can ruin the experience.
4 Weak heating system
Electric heaters under 3 kW can’t handle cold evenings or winter.
You’ll be waiting for hours or unable to use the tub at all when it’s chilly
5 No air massage or lighting
Seems minor? Actually, massage and soft lighting create that true spa effect.
Without them, it’s just a big plastic bucket with warm water.
  • Installation and Maintenance
1 Installation:
You’ll need a level, solid base (concrete, wooden platform, or frame)
There must be access to electricity and water nearby

2 The package should include:
Drain and fill system
Water filtration system
Protective cover or thermal cover

3 Service:
Check if the manufacturer has service partners in Europe
Is there a warranty for the shell, electronics, and cladding?
Can replacement parts be ordered in case of damage?
This is where attention to detail can really save you hours down the line.
