IIArchitectural
Integration.

For projects where the basin is designed with the architecture, not installed inside it.

ROCEAN’s design office works directly with architects, designers, and project teams to integrate cold and plunge systems — in composite or stainless steel — into residential, hospitality, wellness, and superyacht environments.

Pre-assembled. Pre-plumbed. Pressure-tested.

A ready-to-connect autonomous system that brings Rocean technology to existing or custom basins — concrete, stainless steel, composite, tiled, stone, or masonry.

Installed in hours, not days. Managed automatically by Rocean OS.
