Water Cremation for Pets vs. Fire Cremation: What to Know

Pet Aquamation vs Fire Cremation: What Every Pet Parent Should Know

Water cremation for pets uses heated water and a small amount of alkali instead of fire. It takes most of a day, and with a private water cremation, your pet’s ashes come home to you, much as they would after flame cremation. Prices are often close to flame cremation, and at one provider we checked, it cost the same as its semi-private flame cremation. In some states, it’s allowed for pets even where it isn’t allowed for people.

Whether you’re planning ahead or making arrangements today, these are decisions about an animal you love. We checked prices at four providers in October 2026. Below are their prices and, where they list them, how long the ashes take and what comes home with them. Most lists of where water cremation is legal are about people, so we also sorted out what that means for pets. It’s part of our pet aftercare and memorial guides, which cover cremation, burial, and the ways families remember a pet afterward.

Key Takeaways

  • Water cremation, also called aquamation or alkaline hydrolysis, uses heated water and an alkali instead of flame. Private water cremation returns your pet’s ashes to you, and communal water cremation doesn’t.
  • The process takes about 18 to 20 hours, much longer than flame cremation.
  • Lap of Love says water cremation returns at least 20% more ashes than flame cremation, and the ashes are lighter in color. If you have an urn in mind, or already have one, the provider can tell you what size fits.
  • Water cremation with your pet’s ashes returned ran about $115 to $500 for a dog or cat at the providers we checked, depending on weight and location, and some include an urn. That’s often close to the cost of flame cremation.
  • Pet water cremation rules don’t always follow the rules for people. As of March 2026, neither New York nor Rhode Island allowed water cremation for people, but both allow it for pets, and a local provider can tell you what applies where you live.

What Is Water Cremation for Pets?

Water cremation is cremation with water instead of flame. It’s also known as alkaline hydrolysis, green cremation, flameless cremation, and bio-cremation. It’s been around since 1888, but it’s only recently become more common for pets, and it’s still hard to find in many areas.

You’ll often see it called aquamation. That name is a U.S. trademark registered in 2023 to one company, Bio-Response Solutions, for its equipment and for cremation services using an alkaline hydrolysis process. We use the general term. Some providers say aquamation in their business names and price lists, and it’s the same process.

Like flame cremation, it comes in two main forms. A private water cremation keeps your pet separate from other pets and returns their ashes to you. A communal water cremation cares for several pets together, and no ashes are returned.

Families choose it for different reasons. For some, water instead of flame feels right, and others choose it for the environment. You can usually arrange it through a vet who works with a provider, or by calling a provider yourself.

What Happens During Water Cremation for Pets, Step by Step

In water cremation, a pet rests in a vessel of heated water and a small amount of alkali for most of a day, roughly 18 to 20 hours. The provider then prepares the ashes, and with a private water cremation, they come home to you.

  1. In a private water cremation, each pet is kept separate from the others. In a communal one, pets share the process, and no ashes are returned. At Cornell University’s veterinary college, each pet in an individual water cremation is carefully identified throughout the process and is cremated in an individual vessel. If you’re choosing a provider now, ask how they track each pet.
  2. One provider describes its mix as 95% water and 5% alkali. The water is heated.
  3. In PetMD’s words, it takes 18-20 hours for aquamation. If the ashes are coming home to you, you can ask when to expect them.
  4. If the ashes come home to you, they may be buried or scattered in a special place as some families choose to do, or you can keep them in an urn.

Keepsakes, Collars, and Time Together

Some providers can make a paw print or save a fur clipping, and some have a quiet room for saying goodbye. Each one handles these a little differently, so if you’re still arranging water cremation, ask what’s offered and mention any collar or tag you’d like to keep.

Reflections Pet Aquamation in Kitchener, Ontario, offers an ink paw or nose print, and a fur clipping of your pet on request. At Peaceful Waters Aquamation in San Diego, the private package with memorial items includes a clay impression of your companion’s paw and a clipping of fur. If your pet has hooves or feathers, ask what the provider can do.

At Reflections, the comfort room offers a tranquil and private space to say a final goodbye. If your pet’s cremation is already done, some keepsake makers work with the ashes themselves.

How Long Does Pet Water Cremation Take?

The water cremation itself takes most of a day, roughly 18 to 20 hours, and the ashes take a few days or more after that. Flame cremation takes a few hours. With either option, the provider prepares the ashes afterward, and with a private service, they come home to you.

How long the ashes take depends mostly on the provider’s schedule. At Cornell’s veterinary college, water cremations are performed at least once per week on Thursdays, and more often as needed. For a pet in Cornell’s care by Thursday morning, Cornell usually prepares individual ashes by the following Tuesday, and large animals can take longer. If you’re planning a memorial for a particular day, a faster return can help. Peaceful Waters offers a 4-day return for an extra $125, though memorial items aren’t included with that option.

For a private flame cremation arranged through a vet, PetMD says it typically takes 1-2 weeks for your pet’s ashes to be returned. When you make arrangements, ask for a date range and whether the ashes will come to your home or to a vet’s office.

Water Cremation Ashes: How They Look and What to Expect

After a private water cremation, your pet’s ashes come home to you. Lap of Love says ashes from water cremation are softer and have a whiter color, and that at least 20% more come home, which matters if you’re choosing an urn.

If you already have an urn, or have one in mind, give the provider your pet’s weight and the urn’s size, and ask them to check the fit.

What comes home with the ashes varies. Cornell provides a Certificate of HydroCremation with ashes from each individual HydroCremation, and a wooden urn is available for $50 for animals up to 175 pounds. One North Carolina funeral home includes a carved wooden urn, a certificate, and an ink nose or paw print with every private water cremation. Packages differ from one provider to the next.

Some providers scatter communal ashes in a set place, such as at sea.

You can keep, scatter, or bury water cremation ashes the same way as any ashes. If you’re thinking about an outdoor location, our guide to where to scatter pet ashes covers the rules and some ideas for the day itself.

Water Cremation vs. Flame Cremation for Pets

The biggest differences are time and how easy each one is to find. Those are the main downsides, and both are practical. Water cremation takes much longer. Fewer providers offer it, too, so distance and travel costs decide it for some families. PetMD puts the difference at 18-20 hours for aquamation vs 1-3 hours for heat cremation. With a private service, what comes home is much the same: your pet’s ashes.

If both are offered near you, the simplest way to compare is to ask each provider the same three things: the total price for your pet’s weight, the date the ashes will come home, and what they’ll come home in.

How Much Does Pet Water Cremation Cost?

Water cremation with your pet’s ashes returned ranged from about $115 to $500 for a dog or cat at the four providers we checked in October 2026. Prices rise with weight and vary by location, and some include an urn. Here’s what each one charges:

  • At Cornell’s veterinary college in Ithaca, New York, an individual water cremation is $115 for pets up to 100 pounds and $200 for pets from 101 to 175 pounds (January 2026 rates). Ashes are not returned for Group HydroCremations, which cost $35 for pets up to 100 pounds.
  • In Shelby, North Carolina, Clay-Barnette charges $140 for pets up to 25 pounds, $150 up to 46, $160 up to 63, $180 up to 99, and up to $240 for pets up to 200 pounds. Its private pet aquamations include a carved wooden urn at those prices, and communal costs $50 or $70, with no ashes returned.
  • Pet Passages in Rochester, New York, starts at $120 for pets up to 20 pounds, then $150 for 21 to 65, $180 for 66 to 110, and $210 for 111 to 225. Those are the same prices as its semi-private flame cremation. Package prices do not include sales tax, as the price list notes.
  • Peaceful Waters in San Diego charges $220 for pets up to 2 pounds, $300 up to 49 pounds, $350 up to 100 pounds, and up to $500 for pets up to 180 pounds. For pets over 180 pounds, the price list says to call for the most accurate estimate of the cost rather than listing a price.

PetMD says some packages may start at less than $100. A 2024 news report put one Ohio provider at $90 to $380. PetMD also notes that travel to a far-off provider, along with a pet’s size, can raise the price considerably. Ask for one price that covers the cremation itself, travel, what the ashes come home in, and anything else you’ve chosen. If aftercare is one of several bills, our guide to end-of-life vet costs can help you plan for all of them.

Pet water cremation is offered in many places where water cremation for people isn’t allowed. The Cremation Association of North America says pet crematories are under different rules and have adopted the process widely, while states were slow to approve it for people.

Here’s where things stood when we checked in October 2026:

  • New York and Rhode Island allow it for pets but not for people. In a 2015 opinion, New York’s attorney general said a business offering it for pets can be licensed as a pet crematorium, and the Brown Daily Herald reported that pet aquamation is legal in Rhode Island, where a facility opened in 2025.
  • For people, water cremation is legal in 26 states as of March 2026, by CANA’s count: Alabama, Arizona, California, Colorado, Connecticut, Florida, Georgia, Hawaii, Idaho, Illinois, Kansas, Maine, Maryland, Minnesota, Missouri, Nevada, North Carolina, Oklahoma, Oregon, South Carolina, Tennessee, Utah, Vermont, Washington, West Virginia, and Wyoming. If your state isn’t on that list, that tells you about people, not pets, and our directory can show whether there’s a pet provider near you.
  • In Canada, CANA’s list of provinces and territories that allow it for people, as of September 2026, is short: Manitoba, Newfoundland/Labrador, Northwest Territories, Ontario, Quebec, and Saskatchewan. Pet rules there are set separately.
  • These rules change over time, so if you’re making arrangements now, a provider near you can tell you what applies.

Why the Rules for People and Pets Differ

For people, whether water cremation is allowed often comes down to state law. Many states have no rules specific to newer methods, and Montana’s law, for example, describes cremation as a process that uses heat. A January 2026 Montana legislative review lists the states where these methods are either expressly legal or legally acceptable for people, 28 in all for water cremation, two more than CANA’s count. The same review found two states that ban it outright for people: New Hampshire and Ohio.

Pet aftercare runs under different rules, as CANA notes, which is why pet water cremation is offered in many places that don’t allow it for people.

Finding a Pet Water Cremation Provider Near You

Our pet water cremation directory lists 22 providers across 14 states and provinces and Washington, DC, and a real person reviews each listing before it goes live. You can search by city or postal code and message a provider at no cost.

Vets are another good place to ask, since a vet may also have contact information for pet crematory or aquamation businesses they work with. If a vet doesn’t currently offer water cremation, Reflections says it’s happy to reach out to them to make arrangements. PetMD also suggests the IAOPCC’s website and the Better Business Bureau as places to search.

Even a long drive doesn’t always rule it out. Some providers can come to your home or a vet’s clinic for your pet, and some can return the ashes to your home afterward. Ask about any fee for that, since it can change the price.

Questions to Ask a Pet Water Cremation Provider

A few questions can help when you’re choosing a provider. Keep this list on your phone for the call:

  1. Is this private or communal, and in a private water cremation, how do you keep each pet separate?
  2. Where will my pet be cared for, and how do you keep track of them until the ashes come home?
  3. When will the ashes come home, and will they come to my home or to a vet’s office?
  4. What will the ashes come home in, and what size urn will they need?
  5. Can I spend time with my pet before the water cremation?
  6. Can you make a paw print or fur clipping, and can I take a collar or tag home?
  7. What does the price include, and are there fees for travel, after-hours care, or a faster return?
  8. Can you care for my pet’s size and species?

The same questions work for flame cremation, and our guide to choosing a pet crematory covers them in more detail. For a horse, our horse end-of-life resources cover euthanasia, aftercare, and grief.

Deciding on Water Cremation for Your Pet and Planning Ahead

For most families, water cremation for pets comes down to distance, timing, and what feels right. If a memorial is set for a certain day, you can ask each provider when the ashes will come home. Some families are drawn to water, and others prefer flame.

If you’re still choosing, you can call more than one provider with these questions. If you’d rather not keep ashes at home, communal water or flame cremation is an option too. A vet can also talk it through with you, including what your pet’s size means for price and timing.

For families planning ahead, writing down your choice and the provider’s number means it’s ready when you need it. Keep that note somewhere easy to find, or with someone you trust.

Frequently Asked Questions About Water Cremation for Pets

Is water cremation for pets the same as cremation?

Yes. It’s a form of cremation that uses water instead of flame. The Cremation Association of North America counts it as cremation and expanded its own definition to include it years ago. You’ll also see it called aquamation or flameless cremation on price lists and provider pages. Some providers use the word cremation for both methods on their paperwork, so it may say cremation either way. Both methods come in private and communal forms, and with a private water cremation, your pet’s ashes come home, as with a private flame cremation.

Does water cremation cost more than flame cremation?

Often it doesn’t, and where it does, distance can be part of the reason. Fewer providers offer water cremation, so the nearest one may be farther away, and travel can add a fee. Prices usually rise with weight, so a cat and a very large dog can differ by $100 or more at the same provider. Some prices include an urn, and some don’t, which can make two quotes hard to compare, so ask what each one covers. Communal water cremation costs the least, and no ashes are returned. If cost is a worry, ask about a payment plan, and you can ask for the quote in writing.

How long until my pet’s ashes come home after water cremation?

Expect days rather than hours, even though the water cremation itself runs most of a day. Some providers, like Cornell, hold water cremations on set days, and the ashes need to be prepared after the process ends. Large animals can take longer. When a vet arranges it, the ashes may go back to the clinic first, and the clinic can let you know when they’re there. A provider can give you a date range when you make the arrangements, and you can call them if it’s taking longer than they said.

Can a horse or a very small pet have a water cremation?

Often, yes. Cornell’s veterinary college says it has cared for animals as small as lizards and parakeets and as large as draft horses and bulls. For horses and other large animals, the price and the arrangements change, and Cornell lists $1,200 for an individual water cremation for a horse between 501 and 1,000 pounds. That takes planning, so ask how a provider can bring your horse into their care. Some providers list prices only up to a certain weight and ask families to call for a quote above it. If you’re choosing a provider for a bird, hamster, reptile, or other small pet, you can ask how they keep each pet’s ashes separate. You can also ask what the ashes will come home in, since a smaller urn may suit the ashes better.

What can I do with my pet’s ashes after water cremation?

You can do the same things you might with ashes from flame cremation. Families keep them in an urn at home, scatter them somewhere that mattered, bury them in a garden or a pet cemetery, or put some in a keepsake. Others hold back a little and scatter the rest, and some scatter everything in one place. If the ashes are being shared among family members, you can ask the provider whether they can divide them among smaller urns or keepsakes. For jewelry or other keepsakes made with ashes, ask the maker whether they work with ashes from water cremation. Some families keep the ashes at home for years, and some keep them for good.
