When it comes to the weight and size of a hot tub, it goes without saying that even a small 3-person hot tub model is going to be heavy – and that’s including when you remove all the litres of water held inside. And if you’re the proud owner of a swim spa, then its overall weight is going to be even higher.

So, with that in mind, if you’re having a new hot tub installed or you plan on moving your current one to a different location, then you’re going to need to account for the weight associated with it to ensure safe transit from point A to point B, as well as calculating whether or not its new base will be strong enough to support it.

But it’s important to note that there are a variety of factors to consider when it comes to weight and hot tub placement, so we’ve pulled together a guide filled with all the necessary insights you need to account for your hot tub’s weight before you move it.

How much does a hot tub weigh?

As you’ve probably already guessed, the weight of a hot tub varies depending on its size, shape, and capacity. In general, a small two or three-person hot tub weighs between 400-700 pounds when empty, and around 3000 pounds when full. And if you have a larger five-person hot tub, this can weigh anywhere between 750-1000 pounds when empty, and 5000-6000 pounds at its heaviest.

Various factors contribute to a hot tub’s overall weight, including its frame, cabinet, and materials used for insulation. There are additional features to bear in mind too, like hydrotherapy and sound systems, as well as LED lighting—all heavy extras.

If you opt for a tub with a hydrotherapy jet system, this will require additional plumbing, pumps, and structural support. Equally, if you integrate extensive lighting, this can add extra weight too. So, to answer the question, ‘How heavy is a hot tub?’, they are substantially heavy, meaning their installation and placement requires careful consideration.

Why is understanding hot tub weight so important?

Understanding just how heavy hot tubs can be is key to ensuring your own safety and the safety of your tub when you move and install it. Placing such a heavy object on a fragile or unstable surface could lead to health and safety issues, as well as irreparable hot tub damage.

But by equipping yourself with the necessary knowledge about hot tub weight, you’ll be able to ensure a safe and enjoyable experience time and time again,

Where should I put my hot tub?

Effective hot tub placement is key to ensuring your safety. So, you’ll need to install it on a stable surface that is both durable and level, with the below being some of the most popular options:

1. A concrete slab

A perfectly level concrete slab is generally considered the best option for supporting hot tubs. It’s reliable and durable, easily taking the weight of even the heaviest of tubs.

However, one drawback of concrete is that it is more permanent than other options, meaning you’ll need to commit to your hot tub placement for the long run. Equally, issues can arise with thinner slabs, so they must be evenly laid and stand at no less than 10.16 cm.

2. Spa pads

Next up we have the option of a spa pad—a stable surface that is made up of interlocking plastic squares. Spa pads are great if you’re looking for something less permanent, as they can be easily disassembled and moved around as you wish. Another benefit is that they are easy to install, providing you with a reliably level hot tub surface in no time at all.

3. Decking

Decking can be a beautiful addition to your garden, and it’s also a fantastic surface on which to stand your hot tub. It does, however, need to be professionally installed and reinforced, ensuring it’s fully capable of supporting your tub’s weight.

Decking makes a great alternative to placing a hot tub directly onto grass. But if soil is your only option, its composition must be assessed by a professional to confirm its suitability.
