We strongly suggest portable fountains be stored INDOORS during winter. Do not allow fountains that must remain outside during freezing winter weather to collect or retain moisture: drain bowl or shell thoroughly; remove statue and pump, storing inside if possible; fill bowl or shell with absorbent material, such as a blanket or towels (small bowls/shells may instead be inverted); cover entire fountain with a fountain cover or heavy-duty plastic sheeting, and secure tightly.
