Aquamation Cost: What Alkaline Hydrolysis Actually Costs in 2026

Aquamation — formally called alkaline hydrolysis — costs between $2,000 and $4,500 in 2026. That puts it above direct cremation ($1,000 to $3,000) but well below traditional burial ($7,848 to $12,000+). The price gap exists because the equipment is expensive, the process takes longer, and fewer providers offer it.

Here is what drives the price and where the hidden costs sit.

What's Included in the Base Price

Most aquamation providers quote an all-inclusive package that covers:

• Transportation of the body to the facility
• The alkaline hydrolysis process itself (3 to 16 hours in a pressurized steel vessel using water and potassium hydroxide heated to 300°F)
• Processing of bone remains into fine white powder
• A basic container or temporary urn for the remains
• Required permits and paperwork

What's typically not included: a permanent urn, memorial service arrangements, obituary placement, and certified death certificates. These add $200 to $1,500 depending on your choices.

Why It Costs More Than Flame Cremation

Three factors explain the premium:

Equipment capital costs — A commercial alkaline hydrolysis unit costs $150,000 to $500,000, compared to $50,000 to $150,000 for a cremation retort. Fewer facilities have made this investment, which limits competition and keeps prices higher.

Processing time — Flame cremation takes 1.5 to 3 hours. Aquamation takes 3 to 16 hours depending on the system (high-temperature pressurized units are faster; atmospheric units at lower temperatures take longer). Longer processing means lower throughput per machine.

Limited availability — As of March 2026, the Cremation Association of North America lists alkaline hydrolysis as legal for human disposition in 26 states, but operational providers exist in far fewer locations. If no provider operates near you, body transportation costs ($1,000 to $3,000 for out-of-state transport) add to the total.

Cost Comparison by Disposition Type

What You Get Back

Aquamation produces about 32% more bone remains than flame cremation because the water-based process preserves more calcium phosphate. The remains are a fine, bright white powder — noticeably different from the coarser gray ash of flame cremation.

You'll need a slightly larger urn. Standard cremation urns hold 200 cubic inches; aquamation remains may need 250 to 280 cubic inches. Factor this into your urn purchase if you're buying separately.

The sterile liquid byproduct is discharged into the municipal wastewater system or, in some facilities, diverted for use as agricultural fertilizer. No tissue or DNA remains in the effluent.

How to Find a Provider

Start with your state's legal status. Alkaline hydrolysis is authorized in 26 states as of March 2026. New York's June 2026 disposition guidance says alkaline hydrolysis is not permitted for human remains in the state. Legal authorization doesn't mean a provider exists near you — some states have the law on the books with zero operational facilities.

Contact your local funeral home and ask directly. Many traditional funeral homes subcontract aquamation to a specialized facility, which adds a transport fee but keeps the process accessible through your existing provider relationship.

If your state hasn't legalized it yet, the nearest option may require body transportation across state lines, which adds $1,000 to $3,000 to your total.

Making the Decision

Aquamation makes financial sense if you want an environmentally lighter alternative to flame cremation and your state has an operational provider. It uses 90% less energy than flame cremation and has a very low environmental footprint.
