Advanced Spacewall™ Lavatory

Mid-cabin Spacewall™ lavatory exterior

Providing up to seven additional inches of cabin space, the Advanced Spacewall lavatory, combined with slight cabin modifications, facilitates additional pitch, passenger count or the introduction of a premium economy cabin without sacrificing seat count. This lavatory is ergonomically designed from the ground up to ensure an optimized use of space while providing a welcoming environment for passengers.

Advanced Flat Wall Lavatory

Mid-cabin Flatwall lavatory interior

In-lieu of optimizing the cabin, the Flat Wall lavatory enlarges the available interior space. Taking advantage of the alternate lavatory layout, customers can choose the layout best suited for their onboard experience. This lavatory type offers a more spacious interior with added amenities, including a larger sink, added countertop and over counter task lighting. Alternatively, you can opt for the interior ergonomic benefits of the Spacewall™ lavatory or of the Flat Wall with an added readily accessible emergency storage drawer on the exterior of the lavatory.

Pax Plus Aft Lavatory Galley Complex

Pax Plus lavatory complex

Through our Pax Plus complete, airlines can free cabin space while accommodating passengers’ special needs. The Pax Plus complex incorporates a Collins Aerospace designed galley and two lavatories. This complex reduces overall galley storage and preparation space, reducing the overall galley capacity to accommodate two lavatories. The Pax Plus has optional DOT-compliance, with a foldable partition between the two lavatories, providing extra room for Passengers with Reduced Mobility (PRM).
