Lighting
The Harmony hot tub includes LED mood lighting in the base of the spa as well as waterline lighting, backlit waterfall and cabinet lighting. With a full range of colours, you set the mood. Whether you want a relaxing deep blue or a romantic red, there are colours for every occasion.

Bluetooth Music
The Harmony hot tub comes as standard with a quality Bluetooth sound system. Simply connect your phone up to the hot tub’s built-in Bluetooth system, click on your favourite song, and away you go!

Massage
Utilising a range of jet configurations in each seat, the Harmony has been designed to provide the user with a unique and tailored massage experience.
This hot tub has been equipped with a range of high-end jets that target key muscle groups in the back area. If you’re someone who would benefit from a top-class hydro-massage, then the Harmony could be the perfect hot tub for you.
What we love about this hot tub is that each seat has a different arrangement of jets, with various jet types (such as directional and rotational) and jet sizes. This ensures that each seat offers a different type of massage to the rest.
Rotational jets offer a deep tissue massage, right where you need it most.
To reap the maximum amount of benefits from this hot tub, we recommend spending around 5 minutes in each seat.

Water Purification
Clarity of water is important; that’s why the Harmony hot tub utilises the very latest in Ozone technology. But what does Ozone do? When used in conjunction with your regular hot tub sanitiser (e.g., chlorine or bromine), ozone will help to kill pathogenic bacteria, viruses and germs. This means that you’ll in turn need less sanitiser, helping to reduce the amount you spend on chemicals whilst keeping your spa water cleaner and clearer.

Eco-HeatLock™ Insulation
Insulation is a vital feature of any hot tub. It plays a huge part in your water’s heat retention, therefore meaning that the level and quality of your hot tub’s insulation directly affects your day-to-day running costs.
The Harmony hot tub comes as standard with Eco-HeatLock™ insulation, a high-density polyurethane foam that has been applied all the way around the spa’s perimeter and floor. The Harmony also contains insulation under the shell, giving this hot tub a two-step method of keeping your running costs down.
Your Harmony hot tub will also come with a thick, insulated cover included in the price.

Control Panel
The Harmony hot tub comes as standard with a K500 Gecko control panel. It’s easy to use, top quality and designed to last.

Frequently asked questions
What’s the difference between 13 amp and 32 amp hot tubs?
To keep it simple – it’s all about power.
13 amp hot tubs are ideal for places with limited power access, like lodges or holiday homes. One of the big plus points is that they can run off a standard 3-pin, IP-rated outdoor socket (though we always recommend hardwiring them to a rotary isolator switch for safety).
Because they use less power, 13 amp models usually have just one pump. That means slightly gentler massage performance, and the heater can’t run at the same time as the jets – so if you’re soaking for a while with the jets on full blast, you might notice the temperature dip a bit. Once the jets are off, the heater kicks back in.
32 amp hot tubs, on the other hand, need a dedicated power supply from your mains consumer unit. This setup is straightforward for a qualified electrician and gives you more oomph all round – stronger massage jets, and the heater can stay on while you’re using the tub. If you’re after a more powerful, consistent soak (especially for regular use or hydrotherapy), a 32 amp model is usually the way to go.
How are your hot tubs delivered?
Most AquaSolus hot tubs are delivered by a two-person team, using a tried-and-tested method.
We stand the spa up on its side, secure it onto a sled (we call it the “ski”), and carefully move it into place. We’ll use decking boards or similar to protect patios, lawns, or gravel as we go.
In some cases, a specialist delivery may be needed – for example, if we need to lift the spa over a wall, use a crane, or build ramps. These types of deliveries do come with extra cost, but we’ll always advise upfront.
Can you get the hot tub up steps?
Sometimes, yes – but it depends on how many, how steep they are, and what kind of access we’re working with. If you’re unsure, just contact us. A member of the team will talk through your access and help determine whether your space is suitable.
What should I consider before my hot tub is delivered?
There are a few key things to think about before delivery day – from access and electrics to your base and how you’ll fill the tub. Here’s a quick checklist to help you get prepared:
1. Access
Hot tubs are delivered standing on their side, using a specialist trolley (the “ski”). This means:
-
You’ll need a clear route that’s at least as wide as the height of your hot tub + 5cm for packaging – usually over 1 metre.
-
Measure the narrowest point carefully and watch for tight spots like gate posts, drainpipes or window ledges.
-
If there are steps, contact us first – we can often manage them, but it depends on height, steepness and how many there are.
-
Crane or Hiab lifts may be required for tight access – we’ll advise if that’s needed. Additional charges apply for specialist equipment or extra team members.
2. Electrics
-
Most hot tubs need a 32 amp power supply and an IP65 rotary isolator switch, installed at least 2 metres from the tub.
-
This must be connected to your mains consumer unit – we recommend using 6mm armoured cable.
-
Always use a qualified electrician. We’re happy to recommend trusted local contractors.
-
If you’re installing a 13 amp hot tub, we recommend using a 16 amp isolator switch for added protection.
3. The Base
Your hot tub needs to sit on a solid, level surface that can handle its full weight when filled:
-
A concrete base (at least 4 inches thick and ideally reinforced) is best.
-
Decking or paving slabs can work too – as long as they’re properly supported with a suitable sub-base.
-
Avoid sinking your hot tub into the ground or decking – it can lead to drainage problems and make servicing harder.
-
If recessing into decking, make sure to leave removable access panels for maintenance.
4. Water Feed
-
No plumbing is required – just fill your hot tub with a hose.
-
Always fill through the filter housing to prevent air locks.
5. Other Considerations
-
Cover lifters need around 18 inches of clearance at the back.
-
Think about future access for servicing and maintenance – don’t box the spa in completely.

How do I maintain my AquaSolus hot tub?
Looking after your AquaSolus hot tub is straightforward – just follow a few key routines to keep it performing at its best:
Water Changes
-
Home use: Change the water every 1–3 months
-
Holiday lets or commercial use: Change the water between guests
Filter Care
-
Home use: Clean filters every 1–2 weeks, replace every 6 months
-
Commercial use: Clean between guests, replace every 3 months
Ozone System Maintenance
-
If your hot tub has an ozone system, the unit should be replaced every 2 years
Annual Service
-
We recommend booking a yearly service with one of our qualified engineers
-
This includes a full check-up, a biofilm flush to deep-clean the pipework, and a full health report on your spa
Water Chemistry
-
Keep your water balanced with regular testing
-
Unbalanced water can shorten the life of the water itself – and in rare cases, damage your spa over time
Follow these simple steps and your Aqua Solus hot tub will stay in great condition – clean, safe, and ready to enjoy.

Delivery is usually around 2 weeks from the time you order.
