When you are grieving, the hardest part is often that everything feels urgent and unfamiliar at the same time. Cremation can be a gentle, practical choice, but families still deserve to understand what actually happens, what is required, and what choices are truly yours. Cremation is also increasingly common in the United States. According to the National Funeral Directors Association, the U.S. cremation rate is projected to be 63.4% in 2025, which means millions of families are learning these same details and asking the same questions.
This guide walks through the cremation process step by step, using clear language with a few helpful technical details, so you can feel steadier. We will cover the paperwork and identification checks, what a cremation chamber retort is, how long does cremation take, what happens during cooling and processing, and what it is like to be handed the cremated remains. We will also spend real time on something families often do not realize they can choose: the cremation container requirements, including the difference between a cardboard cremation container, a wooden container, a cremation casket, and a cremation casket vs rental casket setup for a viewing or service.
Along the way, you will see where your decisions connect to the next steps of funeral planning, like selecting cremation urns, cremation urns for ashes, small cremation urns, keepsake urns, and cremation jewelry such as cremation necklaces. If you are also caring for a beloved animal companion, we will briefly point you to options for pet urns, pet urns for ashes, and pet cremation urns, because many families find themselves walking both paths at different times.
Crematory vs crematorium, and what a “retort” actually means
Families often hear three words that sound interchangeable: crematory, crematorium, and retort. In everyday conversation, crematorium vs crematory is usually not a meaningful distinction. The Cremation Association of North America (CANA) explains that a crematory or crematorium is the building that houses the cremation chamber or chambers. The cremation chamber itself is the enclosed space where the cremation happens, and many people also call that chamber a retort.
It can help to picture it this way: the crematory is the facility, the retort is the chamber, and the crematory operator is the person trained and authorized to operate the equipment. Once you have that vocabulary, it becomes easier to ask questions that feel specific and reassuring, such as “What identification checks do you use before the retort is loaded?” or “Do you require a rigid cremation container?”
Step one: Authorization, timing, and identification
The first step in the U.S. process is not heat or equipment. It is permission and identity. Cremation requires authorization, and the funeral home or crematory will gather the required paperwork before anything is scheduled. There may also be a waiting period set by state or local rules. CANA notes that, in practice, cremation typically occurs at least 48 hours after death, in part because families need time to finalize paperwork and plans and because logistics and scheduling vary by provider.
While paperwork can feel impersonal, it exists for a reason: cremation is irreversible. Most reputable providers focus on a chain of custody and repeated identity checks. CANA describes a system in which the facility assigns an identification number and records it in a cremation log, often stamping it onto a stainless steel disc (or using a barcode-based system). That identification stays with the person through the process and is checked multiple times, including before and after the cremation.
If you are anxious about mistakes, it is reasonable to ask, in plain language, how identification is handled at each stage. You do not need to be confrontational to be thorough. A simple question like “Can you walk me through your identification steps from arrival to return?” is a normal part of careful funeral planning.
Step two: The cremation container, and what choices you really have
Most families are surprised to learn that a container is required even for direct cremation. The body must be placed in a cremation container before entering the cremation chamber. According to CANA, the minimum requirement is that the container be completely enclosed, rigid, leak resistant, and combustible. CANA also notes that families may choose a cardboard or particle board container, a rental casket, a wooden casket, or other combustible options, while metal caskets generally cannot be cremated.
This is where cost and ceremony intersect. If you are choosing direct cremation, you are often choosing simplicity and affordability, and a basic alternative container may be the most appropriate fit. If you are having a viewing or a traditional service before cremation, your family might want the appearance of a casket for the ceremony, but not the cost of purchasing a full casket that will be cremated. That is where rental caskets come in.
At a practical level, you can think of container options in terms of what the day needs to hold. A sturdy fiberboard or cardboard alternative container may be enough for a private goodbye. A wooden cremation container may feel more substantial if there will be a brief family gathering. A rental casket can provide the visual and ceremonial presence for a service, while the inner container meets the crematory’s requirements.
It also helps to know your consumer rights. The Federal Trade Commission explains in its Funeral Rule guidance that, for direct cremation, consumers can use an alternative container, and the guidance describes alternative containers as enclosures made from materials like fiberboard or composition materials. The FTC guidance also addresses required disclosures and pricing transparency, which can be especially important when you are comparing providers or trying to understand why two quotes differ so much.
If you want a clear, family-friendly explanation of casket and rental options, Funeral.com’s guide Casket Choices Explained: Materials, Features, Rental Options, and Saving on Costs can help you connect these decisions to real-life budgets and service plans without making it feel like you are “shopping” in the middle of grief.
Step three: What happens in the cremation chamber (retort)
Once paperwork is complete and the cremation is scheduled, the facility confirms identity again and prepares the container for the chamber. CANA describes a process where staff confirm the identity against paperwork and the identification disc, then place the container into the primary chamber. The cremation is then monitored carefully until completed.
Families often ask, “What happens to the body during cremation?” It can be comforting to understand the process without graphic detail. Cremation is essentially controlled combustion that reduces soft tissue and leaves bone fragments that are later processed. CANA describes cremation as a conversion of solid material to gas through heat and combustion. It also explains that the combustion process proceeds in stages, with primary combustion in the main chamber and gases moving to a secondary chamber where combustion continues, while bone fragments remain in the primary chamber.
In terms of temperature, CANA notes that laws vary by state, but the cremation process usually occurs between 1400 and 1600 degrees Fahrenheit. Timelines vary too. CANA describes the cremation itself taking anywhere from about 30 minutes in certain cases to over two hours depending on body size and stored heat in the chamber. In everyday terms, many adult cremations take a couple of hours, but the best way to know what to expect is to ask your provider about their typical scheduling and turnaround time in your situation.
If your family wants more context for timing, Funeral.com’s article How Long Does Cremation Take and What Families Can Expect Next walks through common reasons timelines vary, including paperwork, facility scheduling, and whether a service is happening before or after the cremation.
Step four: Cooling, processing, and what “ashes” really are
When the cremation is complete, the remains must cool before they can be processed. CANA describes the bone fragments being carefully removed into a cooling tray, allowed to cool, and then taken to a processor. The processor reduces the fragments to a more uniform, sand-like consistency. That final texture is what most people think of when they picture ashes, but it is more accurate to think of cremated remains as processed bone fragments.
Families also wonder about the amount. CANA notes that the average weight of adult cremated remains is between four and six pounds, which can feel surprising if you expected a small amount or, conversely, something much heavier. Color and texture vary based on bone density, the container materials, and the specifics of the cremation cycle, so it is normal for one family’s remains to look a bit different from another’s.
During processing, facilities also remove non-organic materials. CANA explains that metal may be present due to surgical implants or dental work, and that metal is separated from the cremated remains before processing. The identification disc remains with the person and is typically placed in the container with the cremated remains at the end, so the chain of identity continues through return.
Step five: Picking up cremated remains, and what you can expect to receive
“Picking up ashes” is a phrase people say casually, but the moment can land heavily. Many families feel protective, tender, or suddenly unsure they are doing it right. In most cases, you receive cremated remains in a sealed bag placed inside a temporary container unless you have already selected a permanent urn. You also receive paperwork, and often a certificate or document associated with the cremation, depending on the provider and state requirements.
If you would like a gentle walkthrough of what comes home with you and how to store it safely while you decide next steps, Funeral.com’s article What to Expect When You Receive Cremation Ashes: Handling, Storage, and Next Steps is designed for that exact moment. It also connects naturally to the next question that usually follows: what to do with ashes.
There is no requirement that you choose a final urn immediately. It is common to keep the remains in the temporary container for a period of time while the family decides whether they are keeping ashes at home, planning burial or inurnment in a cemetery or columbarium, scattering, sharing among relatives, or using a portion for keepsakes. If you want guidance on home storage and household safety, Funeral.com’s guide Keeping Ashes at Home: How to Do It Safely, Respectfully, and Legally is a practical place to start.
Choosing the right urn and memorial options, based on your real plan
Once you know the process, the next decisions become less overwhelming because they are no longer abstract. Instead of thinking, “Which urn is nicest?” you can think, “What do we actually need our urn to do?” A home memorial might call for a stable, display-friendly option. A cemetery might have requirements for burial urns or for placement in a niche. Scattering plans might call for a scattering tube or a biodegradable option, and travel plans may influence the kind of closure or container you want.
If you are ready to browse, Funeral.com’s collection of cremation urns for ashes is the broadest starting point, because it includes many styles and sizes in one place. If you already know you want something smaller for a portion of remains, or you are planning to share, you may feel calmer starting with small cremation urns or keepsake urns, which are designed specifically for smaller portions and multiple-family memorials.
Sometimes the most comforting option is something you can carry. Cremation jewelry is designed to hold a very small amount of cremated remains (or another tiny keepsake). If that idea feels supportive, you can explore Funeral.com’s cremation jewelry collection, including cremation necklaces, when you are ready. Many families choose a combination: one primary urn for the home or cemetery, paired with a keepsake urn or jewelry for one or more relatives.
And if your grief includes an animal companion, you are not alone. Pet cremation is a parallel world with its own sizes and styles, and it can help to know that beautiful options exist. Funeral.com’s collections for pet urns for ashes, pet cremation urns in figurine styles, and pet keepsake cremation urns can be a gentle resource if and when you need it.
If you want a scenario-based guide that starts with your plan rather than product categories, Funeral.com’s article How to Choose a Cremation Urn That Actually Fits Your Plans (Home, Burial, Scattering, Travel) is written to help families match an urn to the reality of where the remains will go and what the family hopes the memorial will feel like over time.
What to do with ashes: keeping, scattering, and water burial
When families say they want “scattering,” they usually mean one of two things: scattering a portion in a meaningful place, or scattering all of the remains and keeping only a small amount in a keepsake. Either way, it helps to think about wind, privacy, and local rules. If your plan includes a cemetery, ask about any container requirements for inurnment or burial, because rules can vary by cemetery and by whether the urn goes into the ground, a niche, or a family grave space.
If you are drawn to water burial, it is important to separate the poetic phrase from the legal requirements. In U.S. ocean waters, the U.S. Environmental Protection Agency describes a general permit under the Marine Protection, Research and Sanctuaries Act that authorizes burial at sea of human remains, including the release of cremated remains, under specific conditions. The EPA explains, for example, that placement of human remains in ocean waters within three nautical miles from shore is not allowed under the general permit, and it also provides guidance about materials that should not be placed in the ocean environment. If a water ceremony is meaningful to your family, Funeral.com’s guide Understanding What Happens During a Water Burial Ceremony can help you think through the practical details with care.
How much does cremation cost, and how to compare providers clearly
The cost question is not just financial. It is often about protecting your future self from regret. Families want to know they made a respectful decision without being pressured into unnecessary expenses. Costs vary widely by region and by the type of service, but it can help to anchor your expectations with reputable benchmarks. On its statistics page, the National Funeral Directors Association reports that the national median cost of a funeral with cremation was $6,280 in 2023 (and the median cost of a funeral with viewing and burial was $8,300). Many families spend less than the median when choosing direct cremation, and others spend more when combining cremation with a viewing, ceremony, or additional memorial elements.
If you are comparing providers, remember that the “cremation price” can include different bundles. Transportation, sheltering or storage, required paperwork, the crematory fee, the cremation container requirements, and the return container may be included or itemized separately. The best way to protect yourself is to ask for the General Price List. The Federal Trade Commission explains that the Funeral Rule requires providers to give a General Price List to anyone who asks and includes required disclosures related to direct cremation and alternative containers. That one document can help you compare “apples to apples” instead of comparing a low headline number to a more complete package elsewhere.

Purchase-focused tips: choosing a container and urn that match your budget and service
If you are planning direct cremation, the simplest path is usually an alternative container that meets the crematory’s requirements, paired with a temporary container for return. You can bring the remains home and choose a permanent urn later, when your mind is clearer. When you are ready, browse cremation urns for ashes and let your plan guide the material: display at home, burial, inurnment, or scattering.
If you are planning a viewing or a formal service before cremation, ask about a cremation casket vs rental casket approach. Many families want the comfort of a traditional ceremony without the cost of purchasing a full casket that will be cremated. A rental casket can provide the ceremonial presence, while the inner container meets cremation requirements.
If your plan includes a cemetery, ask the cemetery first about their rules, then buy accordingly. Some cemeteries require an urn vault or a certain kind of urn for burial. Others are flexible. Knowing those rules early can prevent you from buying something beautiful that later needs to be replaced or supplemented.
If your plan includes sharing, build that into the purchase from the beginning. One main urn plus several smaller keepsakes often feels more peaceful than trying to divide ashes later in a rushed moment. Funeral.com’s keepsake urns and small cremation urns collections are designed for exactly this kind of family reality, and adding cremation necklaces can be a meaningful option when someone wants a private, wearable form of remembrance.
Finally, if you are still unsure, give yourself permission to make the next decision only. You can choose a provider and a container first, then choose an urn later. You can keep ashes in a temporary container while you decide. You can plan a memorial service after cremation if that is what your family needs. The goal is not to rush toward a “perfect” answer. The goal is to move through the process with enough understanding that your choices feel like care.
