How it's made

Engineered like a yacht.

Built by Rocean.

Antoine Richer, founder and naval architect, leads the design of every Rocean model. Ergonomics, lines, materials: each element has its place and purpose.

01

Form, proportions, immersion posture. Each bath is the result of our in-house design studio - engineered for the body, drawn for the eye.

02

Laminated composite, reinforced structure, gelcoat finish. The same standard as sailboat hulls - resistant to UV and time.

03

Thermal unit, hydraulics, filtration, custom components, fully assembled by our teams, piece by piece. Designed for uncompromising performance.

by design.

You operate a premium contrast bathing experience. Daily technical oversight should not be part of your team's workload.
Rocean OS continuously manages water quality, compliance and system health - so your team can stay focused on the guest experience.

Operational load reduced
8 h / week 1.5 h
Up to 81% reduction of weekly maintenance time

Water renewal, chemical dosing, filter backwash, hardware diagnostics and UV disinfection: one autonomous, automated operating system. It predicts anomalies, self-corrects, and holds every threshold without daily intervention - zero unplanned downtime.

The Digital Compliance Log timestamps every cycle, every dose, every check. Your records stay audit-ready at all times: zero compliance risk.
