Striking a balance between function, shelter, amenity and accessibility, the Tahunanui Beach toilet block is grounded by the functional aspect of the two banks of toilet blocks, which provide shelter for those escaping the prevailing breeze.

Replacing public facilities previously on the site, the building provides public (including accessible) toilets, unisex and family changing rooms, external showers, a drinking fountain with bottle filler and a well-drained foot wash to clean sandy feet.
