The Product

What this is

Onyx is drawn as a rectangle with no visible radius: a matte black composite shell with a mitred rim and a concealed overflow channel. Against concrete or dark stone it disappears into the room until it is lit. The interior is a deeper charcoal so the water reads black, which owners consistently describe as the most calming part of the design. Chiller and filtration are housed in a matching low cabinet.

The Experience

How it feels

Questions

Frequently asked

How is the water kept clean?

Every plunge in the collection runs continuous filtration with ozone and UV sterilisation. Your team provides a simple weekly and monthly water-care routine at handover.

Does it need plumbing?

No permanent plumbing is required. The vessel is filled and drained periodically; a nearby floor drain makes maintenance easier but is not essential.

How much does it cost to run?

Running cost depends on your set temperature, ambient room temperature and local rates. Insulated covers materially reduce it.
