Frequent questions...

Do you deliver the 500 Series (13A Plug & Play) in my area?

We deliver our hot tubs all over the UK mainland... so if you live in England, Scotland or Wales then yes, we do!

Can you deliver with a crane?

We don't have a crane ourselves, but we can help you to source a crane for delivery over the top of your property or to an upper level.

Should I use chlorine or bromine?

This is entirely personal choice. Chlorine is the most common chemical for a hot tub and for maintaining clean water, but bromine can be suitable for those with chlorine sensitivity. Speak to our team to learn more.

What ground work do I need for the 500 Series (13A Plug & Play)?

We recommend a hard, flat ground with a poured concrete base that has been levelled off.

You can then add gravel, bark or anything else around this to create a decorative effect.

We can also install on patios (as long as they're flat) and decking if it it reinforced.

Speak to our friendly spa specialists if you're not sure.
