Designed with sensitivity towards less able users, Stak is a stackable portable toilet for events that promises to maximize the space on trucks allowing 16 toilets to be transported at once which greatly reduces the cost and also improves user comfort and hygiene. Created by Darmayanti Adisusanto, a student at the University of Technology Sydney, the concept seeks to capitalize on the space inside the toilet by improving the design of toilet seat, incorporating sanitation with better hygiene, and light.
Using Rotational molding (High Density Polyethylene with UV stabilized color fastness) for the main parts (wall, door, waste tank, and roof) the structure is able to achieve maximum strength, toughness, and durability, whilst reducing the tooling cost.
The design of the parts themselves also reduces assembly cost and allow parts to be replaceable improving maintenance. An entrant at the Australian Design Award, Stak seeks to provide innovation and improvement to the current portable toilet for events and that too at a reasonable price.
