When a pet passes away, most families are given two aftercare options: flame cremation or aquamation (also called water cremation or alkaline hydrolysis). Both return your pet's remains to you in a similar form but the process, cost, and environmental impact differ. Here's what actually separates the two, so you can make the choice that feels right for your family.
The short version: flame cremation uses high heat, is widely available, and is typically the more affordable option. Aquamation uses a gentle water-based process, is considered more environmentally friendly, and generally costs somewhat more mainly because fewer providers offer it.
How Flame Cremation Works
Flame cremation uses intense heat to reduce your pet's remains to bone fragments, which are then processed into what most people know as ashes. The process usually takes one to three hours, depending on your pet's size.
There are two forms of cremation: private, where your pet is cremated alone and you receive only their remains, and communal, where multiple pets are cremated together and remains generally aren't returned to individual owners. Private cremation is the more common choice for families who want to keep their pet's ashes.
How Aquamation Works
Aquamation, also called alkaline hydrolysis or water cremation, achieves a similar outcome through a different process. Your pet is placed in a stainless steel vessel with a solution of mostly water and a small amount of alkali. The solution is gently warmed and circulated for several hours, which breaks down soft tissue and leaves the bones behind. Those bones are then processed into a fine powder that looks much like traditional cremated ashes.
Because there's no flame involved, many families find the process feels gentler and it comes with a meaningfully smaller environmental footprint.
Aquamation vs. Cremation: Quick Comparison
Process. Flame cremation uses high-heat incineration. Aquamation uses a water-and-alkali solution.
Example private pricing. Flame cremation runs $190–$435 by pet weight, based on published pricing from Pet Angel Memorial Center in Georgia. Aquamation runs $375–$920 depending on privacy level and pet size, based on published pricing from Resting Waters in Seattle.
Environmental impact. Flame cremation has higher energy use and emissions. Aquamation has significantly lower energy use and emissions.
Availability. Flame cremation is widely available nationwide. Aquamation is available in most states, but with far fewer providers.
What you receive. Flame cremation returns cremated remains (ashes). Aquamation returns processed bone remains, similar in appearance to ashes.
What Does Each Option Cost?
Pricing for both options varies significantly by location, provider, and your pet's size, so it's worth getting a direct quote from a local provider. To ground this in real numbers rather than a national estimate, here are two published price lists from actual providers:
Flame cremation: Pet Angel Memorial Center, an IAOPCC-accredited pet crematory operating across Georgia and several nearby states, prices private cremation by pet weight from $190 for pets under 2 lbs up to $435 for pets over 150 lbs (transportation billed separately).
Aquamation: Resting Waters, a dedicated pet aquamation provider in Seattle, prices individual aquamation with remains returned at $375 for pets under 15 lbs and $459 for pets 15 lbs and over. Their fully private aquamation service, where no other pets are present during the process, runs $750–$920 depending on size.
Comparing those two data points directly, aquamation runs meaningfully higher than flame cremation for a similarly sized pet more than the "10–30% more" range sometimes quoted online. That said, these are two regional examples, not national averages, so actual pricing in your area may look quite different. Always confirm directly with a local provider.
Which Option Is Better for the Environment?
Aquamation is generally considered the more eco-friendly choice. Research has found that the process uses only a fraction of the energy required for flame cremation and produces substantially fewer greenhouse gas emissions. The wastewater created during the process is sterile and safe to be released through standard sewage treatment.
Flame cremation, by contrast, uses more energy and produces more emissions though it remains a widely accessible, well-established option in nearly every part of the country.
Is Aquamation Legal for Pets?
Yes, in effect, almost everywhere. It's easy to find confusing "state legality" maps online, but those typically refer to aquamation for human remains, which is regulated under separate funeral law and varies state by state. Pet aftercare is regulated differently, and aquamation providers for pets operate legally across the vast majority of U.S. states. The real limiting factor usually isn't legality it's simply whether a provider offering the service exists near you.
Frequently Asked Questions
What's the main difference between aquamation and cremation for pets? Flame cremation uses high heat to reduce remains to bone fragments. Aquamation uses a water-based alkaline solution to achieve a similar result. Aquamation is generally considered gentler and more environmentally friendly, but it isn't as widely available.
Is aquamation more expensive than cremation? Usually, yes. As one real-world comparison, Pet Angel Memorial Center (Georgia) prices private flame cremation from $190 to $435 by pet weight, while Resting Waters (Seattle), a dedicated aquamation provider, prices individual aquamation with remains returned at $375–$459, and fully private aquamation at $750–$920. These are two regional examples rather than national averages, so pricing near you may differ check with local providers directly.
Is aquamation legal where I live? For pets, aquamation is legal in the vast majority of U.S. states. The legality maps that suggest otherwise almost always refer to human aquamation, which is regulated separately. Availability of a local provider is usually the bigger factor than legality.
Which option should I choose for my pet? It comes down to your priorities. If environmental impact matters most to you and a provider is available nearby, aquamation may be the better fit. If cost or availability matter more, flame cremation remains the more accessible option in most areas. There's no wrong choice both allow you to keep your pet's remains close.
After the Process, a Place to Keep Them Close
Whether you choose cremation or aquamation, most families want the same thing afterward: a meaningful, lasting place to keep their pet's remains. That's where a well-made urn matters — something that feels as unique as they were, not just a container.
