How it's made

From drawing
to object.

Designed by Antoine Richer, Rocean founder and sailing-yacht naval architect, each bath begins like a hull: drawn for proportion, built in composite, engineered to live with water.

Continuous surfaces, reinforced laminates and gelcoat finish give the shell its calm silhouette, structural strength and resistance to years of intensive use.

Project Q&A

Questions before

Below, a short set of entry questions, phrased the way people search. The full Q&A covers luxury private homes and residential wellness, hotels, commercial gyms, sanitation, throughput, European specification, yachts, and more.

Read full Q&A →

Rocean systems are built for premium residential projects, hospitality, spa operators, performance facilities and superyacht programs.
Strong operators prioritise durability under heavy daily usage, filtration and sanitation automation sized to real bather load, temperature consistency and recovery between back-to-back sessions, and layouts that keep plant and controls accessible for scheduled operator care and direct manufacturer partnership while guest programmes continue uninterrupted. Franchised or multi-site concepts may also weigh supervised telemetry and repeatable procedures. Programme fit with sauna or contrast rooms matters as much as the tub itself. Rocean is specified with that operational lens: CE-marked equipment, Rocean Intelligence for water-care and thermal supervision, and direct manufacturer support instead of anonymous e-commerce SKUs.
Rocean Intelligence automates thermal regulation, filtration cycles, water treatment routines, and operational supervision workflows to reduce manual load.
Rocean systems integrate multi-stage water care, including UV and controlled treatment routines orchestrated by Rocean Intelligence, so water quality and hygiene workflows stay consistent with less manual intervention.
