The right dimensions for your hot tub: what you should pay attention to

Choosing a hot tub is fun. Until you see the list of dimensions. Suddenly, it feels like you're no longer focused on relaxing bubbles, but on math. What does "diameter 180 cm" actually mean in practice? How many people can fit in there without elbowing? And how do you know that round wooden tub won't take over your entire patio?

Choosing a hot tub is a matter of heart, but choosing the right size is a matter of mind. Fortunately, you don't have to puzzle it out on your own. In this blog post, we'll walk you through all the questions you might have – and answer them in plain language. So you'll soon know exactly which size hot tub is right for your garden, your plans, and your relaxation style.

Why the size of your hot tub is so important

A hot tub isn't a piece of furniture you move around every season. It's an investment in comfort and relaxation. And to get the most out of it (oops, we'll avoid that word!), the dimensions must be just right. Not just for your body, but also for your garden, your family, your friends—and for how you envision relaxation.

Too small means crammed in, elbows pressed together, and little space to relax. Too big means longer heating, more wood, more water—and you might just be sitting in that giant pool by default.

What determines the right size for your hot tub?

1. The number of people who regularly use the hot tub

How many people will be in it at the same time on average? Consider daily use, but also weekends. Are you usually just the two of you, or do you enjoy inviting neighbors, friends, or in-laws?
A compact hot tub for 2 to 4 people is ideal for couples or small households. A larger model (5 to 8 people) offers comfort for families or those who enjoy sharing. And then there are the true community hot tubs – for when you'd like to invite half the street party.

2. The available space in your garden or on your patio

• Grab your measuring tape, because measuring is knowing. Keep in mind:
  sufficient space around the tub (at least 60 cm, preferably more)
  
• access to the bath for cleaning and maintenance
  
• a flat surface that can support the weight (a full hot tub can weigh over 1000 kilos)
  

Tip: Use a garden hose or ribbon to mark out the size in your garden. This will give you an immediate sense of scale.

3. Your body size and comfort preferences

You're not sitting in a bucket—you want to be able to lean, stretch, and float. Are you a bit taller? Then a deeper tub is more comfortable. Do you have back problems? Then a comfortable seat depth is important. And also: do you want to sit with your legs stretched out, or snugly facing each other?

Pay particular attention to the seat depth (not just the tub's height!) and the shape of the seats. Also ask about benches or raised platforms for children or smaller users.

The most popular hot tub sizes (and why)

• Ø 150 cm (2–3 people): Compact, ideal for small gardens or couples. Heats quickly and requires little maintenance.
  
• Ø 180 cm (4–5 persons): Space for the family or a few guests, without the bath becoming too bulky.
  
• Ø 200–220 cm (6–8 people): For those who truly enjoy being together. Imagine long evenings with friends or family.
  
• Custom: Yes, that's possible. If you have specific requests, we're happy to discuss them with you.
  

A bigger hot tub = more work?

Not necessarily. A larger hot tub means more water, that's true. And therefore a longer heat-up time and more volume to keep clean. But with the right accessories (like a lid, filter system, and proper maintenance), it's all perfectly manageable.

In fact, many people find the larger size even more comfortable. More room to move around, stretch your legs, or simply avoid being cramped on hot days.

So it mainly comes down to what you find important: speed and compactness, or comfort and space.

Which shape suits your needs?

Round is the classic. But there are also oval or extra-deep versions. The shape influences the sense of space. Round feels cozy and intimate. Oval often offers a bit more legroom or a more luxurious look. And deep... well, that's just wonderful for those who truly want to immerse themselves.

Take a good look at your garden: where will the tub be placed? How will the space flow? And how will you view the arrangement from your patio or kitchen window?

Practical considerations when choosing dimensions

Consider the following:

• Is there room for steps? Don't forget to factor in the stairs or step.
  
• Where will the stove go? On the side? There needs to be room for that too.
  
• Do you want lighting or accessories? That can also influence the placement.
  
• What about privacy? Is there a screen or hedge around it?
  

You see: it's not just about diameter and depth. It's about the experience surrounding it.

Extra comfort: seats, backrests and depth

A comfortable hot tub isn't just about size; it's also about the design of the seating. A flat bench isn't necessarily comfortable. Gently curved backrests, a raised seat, or a footrest can make all the difference.

Do you have children? Then a shallower seating area is ideal. Do you want to sink to your shoulders? Then choose a deeper tub. Get advice on this – and perhaps test a model in the showroom.

Choice of material also influences the size

A wooden hot tub often has thicker walls than plastic versions. This means the outside dimensions are larger than the seat dimensions. This difference is important when measuring the space. So always ask about the net seating area.

If you choose insulation, keep that in mind when choosing your dimensions.

Does it also suit your style?

Big is beautiful. But too big can sometimes look out of place. A hot tub should complement the rest of your garden: the ambiance, the plants, the patio.

Sometimes a smaller model integrates better and creates a harmonious whole. A large bath with a wooden surround, on the other hand, can be a real eye-catcher. So, don't just think practical, but also aesthetic.
