What is a large hot tub?  

In the UK, a large hot tub generally refers to a tub that has space for six or more people to sit in. These large tubs are ideal for larger families or groups of friends who want to enjoy a relaxing soak together. They can range in size from around 228cm in length and width, and more than 1 metre in height.  


Large hot tubs and extra large hot tubs, especially quality options, are usually equipped with powerful jets that can help ease sore muscles and promote relaxation. They may also come with additional features such as LED lighting, built-in sound systems, and Bluetooth® connectivity.  


When choosing a large hot tub, it's important to consider factors such as   

-Space availability  

-Installation requirements  

-and maintenance needs  

As an example, many models require a solid and level foundation, access to an electrical outlet, and regular water treatment and replacement.  


Ultimately, a large tub can allow you to unwind and socialise with loved ones in the comfort of your own property.
