Rental Caskets are caskets that are intended to be displayed at a funeral, but, in many cases, are not ultimately buried. Rental caskets, sometimes referred to as "cremation caskets" are common when a person is to be cremated but the family wants to conduct a full ("traditional") funeral service in which the body is displayed in a casket before the cremation.
The "alternative container" that funeral homes offer can also be used for a viewing and funeral service before cremation. Similar to the more ornate rental casket, after the service, the alternative container, which is often made of cardboard, will be transferred to the crematory to be cremated. Alternative containers can range from $25+ depending on the funeral home.
As with many funeral options, the choice of using a rental casket is completely personal. If you think a rental casket would be appropriate, be sure to discuss the renting or buying options with your funeral director to find the one that best fits your financial and situational needs.
