Frequent questions...

Do you deliver the Athena in my area?

We deliver our swim spas 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 Neptune?

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.
