This simple water urn will make any water burial ceremony dignified and memorable. Made of sand and a plant-based gel. Designed to float for few minutes, sink and dissolve completely in water, releasing the ashes into the water.

The ashes go into a specifically designed dissolvable bag, that is then placed inside the urn. For the ceremony, place the in the water. The urn will float, then as water starts to fill the urn through small holes at the base. Note – the urn may sink quickly or straight away if there is a large amount of ashes.

Then the combined weight of the water, the urn and the ashes causes the urn to sink slowly under the waves. The urn will breakdown under natural processes, the length of time is variable over a several hours, the exact time will depend on the temperature and the movement and current of the water. The higher the temperature and the greater the movement in water the faster the urn will dissolve.

Water Ceremony

Water burials are a very dignified way to conduct an ashes ceremony. You can cast petals, put last words on our promises notelets. While the simple water urn floats, you will have enough time to say some final words, prayers or thoughts. Many clients find that the simple presence of a body of water after the ceremony can help them to remember that person.

We consider these urns more suitable for deeper water below the low tide line. Please see our page on general guidance for ceremonies or river or the sea.

Finally, it is sensible idea to record where you conducted the ceremony for future generations, if you are on a boat the skipper will be able to tell you your coordinates.
