Reclaim stillness in the KC-4 Serenity Spa Plus – a serene hydrotherapy haven designed for spacious relaxation. With 7 seats arranged for communal connection or individual restoration, this elegant spa invites you to slow down, soak deeply, and reconnect with your natural rhythm.

The KC-4 is more than a spa — it’s a daily ritual. Powered by two quiet-yet-powerful 2HP pumps, it features 59 carefully placed jets for immersive massage therapy. A 3kW heater maintains the perfect warmth while the 0.35HP circulation pump ensures constant clarity. Every session becomes a sanctuary of peace, movement, and mood.

Wrapped in Sterling Silver acrylic and encased in contemporary grey side panels, the KC-4’s design blends into natural landscapes and refined terraces alike. LED perimeter and corner lighting create atmosphere for every occasion, from restorative morning rituals to celebratory evenings.
