How long does it take to do the initial setup?

Our delivery team will have the spa in position within 30 minutes. Once filled with water, which on average takes around 1 hour, they will then take you through the full operation of the spa including how to maintain the water quality. We do not set a time frame on the handover to you, we spend as much time with you as needed and do not leave site until you are happy.

How come your spas look different than the spas I’ve seen elsewhere?

Rotospas are UK manufacturer Roto moulded spas. The spas you may have seen elsewhere are likely to be acrylic spas. Rotospas are specifically designed to be portable and energy efficient. They can be easily moved around which means we nearly never have to use a crane to deliver them. They have built in insulation which means there is no need for any nasty expanding foam or suchlike and are super eco friendly. 

Our spas unique moulding process means that our spas do not feature a separate shell and cabinet. Our monocoque structure is the strongest available on the market and we stand by this with our lifetime shell warranty, our shells will never rot, crack or de laminate. All our spas are designed with limited access in mind, hence the lower profile, however this does not mean that our spas are smaller. Our defined seating positions utilise the internal space and ensure our spas can comfortably accommodate up to 6 adults.

How long is the warranty?

Lifetime warranty on our unique, tough, one piece shell and cabinet structure, 2 years parts 1-year labour. Being British made, you can buy with confidence and know you will have many years relaxation and peace of mind.

What access do you need to get the hot tub in my garden?

Limited access? No problem! We have a RotoSpa model to fit your needs. That’s the pathway we need to set up your hot tub oasis.

What power supply is required?

A standard 240V 13 amp ‘plug & play. 

How much does it cost to run the hot tub?

Between $3 and $5 for a warm embrace. Inflatables? They’re a bit thirstier, guzzling up to $20.

How much power does the spa consume in summer?

With the higher ambient temperatures experienced in summer, you can expect to be amazed at how economical it is to run a Rotospa. If you are energy conscious, we offer an upgrade allowing you to heat your spa using an air source heat pump, THE most efficient way to heat your spa water cutting your total running costs by up to 75%!

How long does it take to heat up?

Just 12 hours to warm paradise! Inflatable spas? They’re more of the ‘slow-cook’ variety, taking 1 to 2 days.
