If you own a hot tub you may have wondered to yourself: how on earth is this giant thing made? Well, we thought we'd show you the process. 

One of the most interesting parts is the shell itself. The acrylic sheet is heated up to extreme temperatures, making it extremely flexible. It is placed over the pre-built mould and then vacuum formed into the shape of your spa.

After this, the shell is left to cool and harden, then it's flipped upside down and sprayed with a thick, dense layer of insulation foam. This keeps the heat in and contributes towards lower running costs. This whole process is done by hand.

Then the spa joins a line going through a cooling and setting process, coming out on the other side ready for the fittings.

At the end of this conveyor system, the pipework and base are both added along with the strong, durable aluminium frame. The spa is then flipped the correct way round for the fitting of the jets, pumps, heater system and filtration system.

Once that's complete, the hot tub goes through a thorough and extremely strict quality control process. This includes filling the spa, checking for any leaks, and heating it up to temperature. The spa is then run on full power with all jets running to ensure quality and consistency.

Finally, the hot tub is turned upside down to drain out the last of the water in the pipework system, ready to be packed up.

The new, shiny hot tub is then packaged extremely carefully to ensure no damage in transit between the factory, our warehouse and eventually your garden.
