Aquabrass INABOX 3-Way Shared Shower System 14″ x 8″ Rainhead INABOX03

A coordinated combination of overhead, handheld, and body spray outlets makes the Aquabrass INABOX03 a versatile choice for contemporary shower installations. This 3-way shared system brings together a 14″ x 8″ oversized rectangular rainhead, a three-function handshower, and three round body jets, providing several ways to direct water within one shower area.

The overhead component uses a 14″ x 8″ rectangular ABS rainhead for broad overhead water delivery. An 18″ round shower arm with matching round flange is included for wall installation. A separate 4″ round ceiling arm is also supplied, providing an alternative arrangement when the rainhead is intended for ceiling positioning. These included options allow the overhead outlet to be planned according to the bathroom’s shower layout.

For more directed water delivery, the INABOX03 includes a push-button handshower with three selectable functions: rain, mist, and jet. The push-button control makes it possible to switch between spray types directly from the handshower. A 28″ overall shower rail provides the mounting structure, while the included handshower hook offers a dedicated place to position the handshower when it is not being used.

Three round body jets add further water outlets to the system. Their placement can provide additional showering options beyond the rainhead and handshower, making the configuration suitable for bathrooms where several water delivery points are required. The adjustable round waterway also supports practical positioning of the components during installation and helps coordinate the outlets with the finished shower layout.

Installation is supported by an easy clip-on fastening system with hidden adjustment. This arrangement is designed to accommodate different wall thicknesses while keeping the visible trim components coordinated. The system uses a 3-way shared configuration, so the required Aquabrass T12123 thermostatic valve must be planned separately, as it is not included with the INABOX03.

The combination of multiple outlets, adjustable installation features, and selectable handshower functions gives this system flexibility for a range of contemporary bathroom layouts. Its coordinated components provide a complete shower outlet arrangement while allowing the overhead, handheld, and body jet functions to work within the same installation.
