Air Button, 1-3/8" Hole, Biscuit AB-03 Spa Tub Air Button

Introducing the NUWHIRL SYSTEMS Air Button AB-03 in Biscuit — a purpose-built, low-profile spa control designed to mount in a 1-3/8" hole and disappear into premium surfaces. Built for thick tubs—think marble or very thick acrylic shells backed by fiberglass—AB-03 delivers precise airflow control without disrupting the tub’s refined aesthetic. Its unobtrusive, seamless profile keeps the spa area looking pristine while providing reliable jet activation when you need it.

What makes AB-03 stand out is its installer-focused design and durable construction. The Biscuit finish blends naturally with common bathroom fixtures and tile work, ensuring a cohesive look in luxury baths, hotel spas, or clinical spaces where appearance and performance matter. A rugged build withstands humid environments and heavy use, while the included mounting nut ensures a secure, behind-the-surface attachment that won’t loosen or wobble over time.

• Exact fit for 1-3/8" holes: engineered for thick surfaces where standard buttons don’t align, ideal for premium tubs.
• Biscuit color with a low-profile, seamless appearance that minimizes visual disruption and matches common bathroom finishes.
• Moisture-ready construction: designed to endure frequent use and routine cleaning in both residential and commercial settings.
• Complete mounting hardware included: built-in nut enables quick, secure installation from behind the surface.
• Effortless, precise push-action: reliable actuation that controls spa airflow exactly when you want, enhancing jet comfort and relaxation.
• Easy integration: designed to work with existing spa controls, upgrading usability without altering the tub’s aesthetic.
