What temperature range does the Rocean Bath reach?

The Rocean Bath and Box both reach temperatures from 3°C to 40°C — functioning as a cold plunge, cold bath, or hot bath. Cooling rate is approximately −4°C per hour.

Is the Rocean bath suitable for hotels and spas?

Yes. Rocean products are specifically designed for professional environments requiring zero daily staff input. Rocean OS autonomously manages water chemistry, filtration, UV treatment, and temperature. Deployed in five-star hotels, premium gyms, superyachts, and UHNW residences worldwide.

What is a contrast bath?

A contrast bath alternates immersion between hot water (up to 40°C) and cold water (as low as 3°C). The thermal contrast stimulates circulation, accelerates muscle recovery, and has measurable effects on HRV and sleep quality. Rocean designs autonomous contrast bath systems for professional and residential use.

Can Rocean supply a system only for a custom basin?

Yes. Rocean supplies its intelligent technology — thermal unit, Rocean OS, filtration system — as a standalone system for architects and spa builders who design their own basin. Available for bespoke projects worldwide.

Where is Rocean manufactured?

All Rocean products are designed, engineered, and assembled in Bordeaux, France, and at a European shipyard using naval composite techniques. No rebadged industrial components — every system is built in-house.
