Transform your bath into a spa-like retreat with the NuWhirl MB2G07500SCB Micro Bubble Pump. This Generation 2 replacement unit combines focused infusion technology with rugged reliability, delivering an ocean of tiny, oxygen-rich bubbles that elevate every soak in both walk-in and traditional tubs.

Infusion technology that truly matters

Billions of microbubbles saturate bathwater, delivering up to 80% more dissolved oxygen than plain tap water. The result is a buoyant, refreshing soak that feels lighter on muscles and skin, while still providing a gentle water massage. This is not just bubbles—it's a water-air partnership that enhances circulation and creates a distinct, spa-grade sensory experience.

• Additive-free rejuvenation: Pure microbubble action delivers a unique sensory experience without extra ingredients.
• Generation 2 reliability: Refined design ensures consistent performance across a range of tub configurations, from freestanding to built-in models.
• Broad compatibility: Widely adopted by tub manufacturers and suitable for walk-in, freestanding, vessel, and traditional bathtubs, making retrofits smoother and more dependable.
• Rugged, moisture-ready build: IP55-rated enclosure protects the motor and electronics in damp bathrooms for longer service life.

• Placement tips: Optimize bubble coverage by aligning the microbubble channels with the main soaking zone—consistent distribution enhances the buoyant lift and massage effect.
