Traditional Cremation vs. Aquamation: What’s the Difference for Your Pet?
When you are planning your pet’s aftercare, you will likely be offered two methods: traditional cremation and aquamation. Most families have never heard the second word before, and it arrives at a moment when you have very little capacity for research.
The short answer is this: traditional cremation uses heat and flame, while aquamation uses warm water and an alkaline solution to accomplish the same thing more gently. Both are respectful. Both return your pet’s ashes to you. The differences come down to the process itself, the environmental footprint, how much ash you receive, and how long it takes.
At Heartstrings Pet Hospice, we offer both, and we do not push families toward either one. Here is what you need to know to choose with confidence.
What Is Traditional Cremation?
Traditional cremation — also called flame cremation — is the method most people picture when they hear the word. Your pet is placed in a cremation chamber and exposed to intense heat, typically in the range of 1,400 to 1,800 degrees Fahrenheit, until only bone minerals remain. Those minerals are then processed into the fine ash returned to your family.
The process usually takes a few hours, depending on your pet’s size. It has been the standard for decades, it is widely available, and it is what most veterinary practices have partnered with for years.
What Is Aquamation (Water Cremation)?
Aquamation — known technically as alkaline hydrolysis, and sometimes as water cremation — uses gentle water circulation, controlled temperature, and alkalinity to accelerate the same natural process that occurs in soil. There is no flame at any point.
How the Aquamation Process Works
Your pet is placed in a stainless steel vessel with a solution of water and alkali. Over a period of hours, the combination of warm water, gentle movement, and alkalinity breaks down the body’s soft tissue, leaving the bone minerals behind — exactly as flame cremation does, only without combustion.
Those minerals are then dried and processed into ash and returned to your family. Because the remains are never exposed to fire, there is no carbon discoloration, so aquamation ashes come back a light sage or soft white rather than the gray of flame cremation.

| Emissions | Combustion byproducts released | No direct greenhouse gas or mercury emissions |
| Ash color | Gray | Light sage to soft white |
| Amount of ash returned | Standard | Approximately 20% more |
| Timeline | Standard turnaround | Add a day or two for drying |
| Available privately or communally? | Yes | Yes |

The Five Differences That Actually Matter
1. There Is No Flame
This is the difference families react to most. For some, the mental image of fire is genuinely difficult, and knowing their pet was cared for in warm water instead brings real relief. For others, flame cremation carries the weight of tradition and feels more familiar. Neither reaction is wrong, and it is a perfectly valid reason to choose one over the other.
2. The Environmental Footprint
Aquamation uses over 90% less energy than flame-based cremation and burns no fossil fuels. It produces no direct emissions of greenhouse gases or mercury. If sustainability shaped how you lived with your pet — the food you bought, the products you chose — aquamation often feels like a natural extension of those values.
3. You Receive More Ash, and It Looks Different
Aquamation returns roughly 20% more ash than flame cremation. The ashes are also finer and lighter in color, a soft white or light sage rather than gray, because the bone minerals are never scorched.
This matters more than families expect. If you plan to divide ashes among family members, fill more than one keepsake, or use a portion in memorial jewelry or glass art, the additional volume gives you room to do it.
4. The Timeline Is Slightly Longer
Aquamation requires an additional day or two, because the remains must be thoroughly dried before they can be processed and returned. If you are hoping to have your pet’s ashes home by a specific date — a family gathering, a memorial, a child returning from school — mention it when you book, and we will tell you honestly whether it is achievable.
5. Availability
Flame cremation is offered nearly everywhere. Aquamation is still less common, and it is not available in every region. If it matters to you, ask early rather than assuming it will be an option.
Does Cost Differ Between Cremation and Aquamation?
At Heartstrings Pet Hospice, private cremation and private aquamation are priced identically, and communal options are priced identically to each other. Pricing is based on your pet’s weight rather than the method you choose.
That is deliberate. We did not want families choosing the process that felt wrong to them simply because it cost less. You can see current pricing on our cremation and aftercare page, and financing is available if you need it.
Both Methods Can Be Private or Communal
One point that often gets tangled: traditional cremation and aquamation are methods, not service levels. Either one can be performed privately, where your pet is handled alone and their ashes are returned to you, or communally, where pets are handled together and ashes are not returned.
So you are really making two decisions: which method feels right, and whether you want your pet’s ashes back. Our private services include your choice of urn, an engraved nameplate, and a certificate, with optional private in-home delivery of your pet’s ashes.
Frequently Asked Questions
Is aquamation better than cremation? Neither is objectively better. Aquamation is gentler and substantially more environmentally friendly, and it returns more ash. Traditional cremation is more widely available and more familiar to most families. The right answer depends on your values, not on any ranking.
Is aquamation legal? Aquamation is legal and well established for pets, and it is offered through licensed facilities. Availability varies by region, so ask us what is offered in your area.
Do you get ashes back from aquamation? Yes, with private aquamation you receive your pet’s ashes and no one else’s — approximately 20% more than flame cremation would return. Communal aquamation, like communal cremation, does not return ashes.
What do aquamation ashes look like? They are fine and powdery, in a light sage or soft white shade rather than the gray produced by flame cremation, because the bone minerals are never exposed to fire.
How long does aquamation take compared to cremation? Aquamation typically adds a day or two to the overall timeline, since the remains need time to dry fully before being returned.
Can I choose aquamation for in-home euthanasia? Yes. Our in-home euthanasia service includes aftercare guidance, and you can select aquamation or traditional cremation, private or communal, as part of that visit.
Honoring Your Pet, Whichever You Choose
There is no wrong answer here. Some families choose aquamation because the gentleness of it brings comfort. Others choose traditional cremation because it is what their family has always done, and that continuity matters. Both are handled with the same dignity, and both give you a way to keep your pet close.
