In pursuit of the perfect sand castle, we’ve been known to scout real estate the night before a beach day.

But a prime location isn’t worth much without a well-equipped contractor.

Set your little architect on a path to success with Haba’s new collapsible water bucket. The lightweight nylon bag has a valve that lets you control the flow of water. When your sand seems too dry, give the nozzle a turn to release only what you need — no worries about washing away your building materials or turning a tunnel into a moat.

The bucket also packs flat, taking up less space in your beach tote than a traditional plastic bucket. And with sunblock, towels, sippies, and snacks, we know how valuable that real estate is.
