Water Urns Explained: Designed for Scattering at Sea

A water urn is designed to be placed gently on the surface of water, where it floats briefly before dissolving completely, releasing the ashes in a slow, graceful, and dignified way. They're purpose-built for sea, lake, or river scattering ceremonies and are typically made from water-soluble paper, salt, or other biodegradable materials.

How a water urn ceremony typically works

  1. The urn is gently lowered or placed onto the water's surface, either from a boat, jetty, or shoreline.
  2. It floats for a period — often several minutes — allowing family and friends a quiet moment to watch, reflect, or say a few words.
  3. The urn gradually dissolves, releasing the ashes naturally into the water.

Materials used

Water urns are commonly made from water-soluble paper, natural salt compounds, or a biodegradable gelatin-based material — all specifically designed to dissolve fully within minutes to a couple of hours, leaving no lasting trace.

Why families choose a water urn ceremony

  • It offers a gentle, visual moment of release, rather than simply pouring ashes directly into the water.
  • It's environmentally conscious, using fully biodegradable materials.
  • It suits a planned, ceremonial moment — often accompanied by flowers or a small reading.

Where to hold the ceremony

Most families choose the sea, but water urns work equally well on a lake or river. See our guide on scattering ashes at sea in Australia for guidance on choosing a location respectfully.
