1. Which Onyx Spa is right for me?

The best model depends on how many people will use the spa, the space you have available, and the type of seating you prefer.

If you enjoy sitting together and talking, a round or all-seat model may be a great choice. If you prefer to stretch out and fully relax, consider one of our lounger models.

Onyx offers a variety of layouts for 5 to 8 people. If you’re unsure, contact us and we’ll help you choose based on your space, lifestyle and budget.

2. How many people can an Onyx Spa accommodate?

Capacity varies by model.

The current Onyx range includes 5-person, 6-person and 8-person spas, with round seating, all-seat layouts, single loungers and double loungers available.

We recommend considering not only maximum capacity, but also how many people will normally use the spa and the seating style you find most comfortable.

3. What do the hydrotherapy jets do?

Onyx Spa jets are positioned to deliver soothing water massage to different areas of the back and body, helping you relax and unwind.

Different seats provide different massage experiences, allowing you to choose the position that feels best for you. The X5R, for example, is specifically designed around targeted hydrotherapy.

4. Can an Onyx Spa be installed outdoors?

Yes.

Onyx Spas are ideal for backyards, patios and other private outdoor spaces, creating a relaxing place to enjoy throughout the seasons.

The installation area should be level, stable and capable of supporting the full weight of the filled spa, with suitable access to electrical service, drainage and maintenance areas.

5. What should I prepare before delivery?

Before your spa arrives, we recommend preparing:

  • A level and structurally suitable base
  • Clear access for delivery
  • The required electrical connection
  • Suitable drainage
  • Enough space around the spa for servicing and maintenance

Requirements vary by model, so always refer to the specifications and installation instructions for your chosen spa.

6. What electrical supply does my spa require?

Electrical requirements vary by model.

Please refer to the specifications for your selected spa and have all electrical work completed by a qualified electrician in accordance with local electrical codes.

If you’re unsure whether your existing electrical supply is suitable, contact us before ordering and we’ll help confirm the requirements for your model.

7. How often does the spa water need to be changed?

This depends on how frequently the spa is used, how many people use it and how well the water is maintained.

Regular water testing, proper filtration and correct sanitizer levels help keep the water clean and comfortable for longer.

Always follow the recommended water-care instructions supplied with your spa.

8. Is an Onyx Spa difficult to maintain?

Routine maintenance is straightforward, but it should be done regularly.

Typical care includes checking water chemistry, cleaning the filters, maintaining the correct water level, cleaning the spa surfaces and periodically checking the equipment.

Good maintenance helps protect both water quality and the life of your spa.

9. Can I use my spa during winter?

Yes.

For many owners, cold weather is one of the best times to enjoy a hot spa — warmth, whatever the weather.

In freezing climates, the spa should remain powered and operating normally. If it will be shut down for an extended period, proper winterization procedures should be followed.

10. Does my Onyx Spa come with a warranty?

Yes. Every Onyx Spa comes with a 1-Year Warranty.

Specific coverage, parts and warranty conditions should be confirmed in the Warranty Policy supplied with your spa.

If you require support, please contact us with your spa model, serial number and a description of the issue.

11. Can I return my spa?
