No federal or state law requires you to buy a burial vault. Burial vault requirements, when they apply, come from the cemetery where the burial takes place, not from any government. Most cemeteries do insist on some kind of outer burial container so the ground above the grave doesn’t sink, but you have real choices about what kind you use, where you buy it, and how much you spend.
What Federal Law Says
The Federal Trade Commission’s Funeral Rule, at 16 CFR Part 453, governs how funeral goods are sold in the United States. It does not require vaults. It requires the opposite: every funeral provider must disclose to you, in writing, that you are not legally obligated to buy an outer burial container.1eCFR. 16 CFR Part 453 – Funeral Industry Practices That disclosure appears on the Outer Burial Container Price List, or right next to vault prices if they’re listed on the General Price List.
The FTC’s own language, which funeral homes are required to print, states that in most areas of the country state and local law does not require an outer container, that many cemeteries do require one so the grave will not sink, and that either a grave liner or a burial vault will satisfy those requirements.2eCFR. 16 CFR Part 453 – Funeral Industry Practices – Section: 453.3 Misrepresentations If a funeral director tells you a vault is required by law, that is a federal violation.
The Requirement Actually Comes From the Cemetery
Cemeteries set their own outer container rules through interment agreements, which are contracts you sign before burial. The reason is practical. An unprotected casket eventually collapses under the weight of soil and grounds equipment, and a sunken grave is both a safety hazard and a maintenance expense the cemetery wants to avoid.
Most cemeteries accept either a grave liner or a burial vault. Some require a full vault. The written policy will spell out the minimum. Before you purchase anything, ask the cemetery for a copy of the interment agreement. If you don’t meet the container requirement, the cemetery can refuse to perform the burial, so confirming the rule up front saves both time and money.
Burial Vault Versus Grave Liner
The two terms often get used interchangeably, but they describe different products.
A grave liner covers the top and sides of the casket and leaves the bottom open. The casket rests directly on the earth. A liner keeps the ground from caving in but does not seal out water or soil. It is the least expensive option, and it satisfies cemeteries whose only concern is ground stability.
A burial vault fully encloses the casket on all six sides and uses a sealed lid to resist moisture. Vaults come in sealing designs that either use a gasketed lid-to-base joint or trap a pocket of air inside the container to keep water away from the casket. Reinforced concrete is the most common material, often with an inner liner of high-impact plastic, stainless steel, or copper for corrosion resistance. Metal vaults are typically steel. Polymer vaults are lighter and generally less expensive than lined concrete.
Typical Costs
Prices vary widely with material, construction, and whether the container is sealed. As a rough framework:
- Concrete grave liner, unsealed: $400 to $1,500
- Single-reinforced concrete vault: $600 to $2,000
- Double-reinforced concrete vault: $2,000 to $4,000
- Premium lined vault with copper, stainless steel, or bronze liner: $3,000 to $6,000 or more
- Polymer or plastic vault: $1,000 to $2,000
The vault itself is not the only charge. Most cemeteries add a setting fee for the labor of lowering and positioning the vault in the grave, typically a few hundred dollars. Delivery from the manufacturer or supplier can add another $100 to $400. Ask for itemized pricing from both the funeral home and the cemetery so you can see the markups line by line.
You Can Buy the Vault From Somewhere Else
Even when the cemetery requires an outer container, you do not have to buy it from the funeral home. The Funeral Rule prohibits funeral providers from penalizing you for buying a casket, vault, or other merchandise elsewhere. The FTC calls surcharges on outside purchases a “hidden penalty” and treats them the same as any other prohibited fee.3Federal Trade Commission. Complying with the Funeral Rule A funeral home cannot refuse to handle the burial because you brought your own vault, and it cannot add a handling fee to discourage the practice.
Independent vault companies, online retailers, and wholesale suppliers often sell the same products for less than funeral homes charge. If a funeral director resists an outside purchase, ask for the refusal in writing. That request generally ends the conversation.
Urn Vaults for Cremated Remains
If you’re burying cremated remains in a cemetery plot, many cemeteries require an urn vault for the same reason they require a container for a casket. An unprotected urn can shift or crush under soil pressure and leave the ground uneven. Urn vaults are much smaller and much less expensive than casket vaults, typically $100 to $400.
Accepted materials usually include concrete, metal, fiberglass, and reinforced polymers. Some cemeteries do not accept wood or biodegradable urns in their traditional sections. This is a cemetery policy, not a legal requirement. Church cemeteries, natural burial grounds, and some municipal cemeteries allow direct earth burial of an urn with no outer container. Check the specific rules before you buy.
Veterans Buried in a National Cemetery
Veterans buried in a VA national cemetery receive an outer burial receptacle at no cost as part of their burial benefits.4U.S. Department of Veterans Affairs. Burial and Memorial Benefits for Veterans The VA supplies a government-furnished grave liner for every casketed burial in those cemeteries, so the family does not need to purchase one.
For burials in VA grant-funded state or tribal veterans cemeteries, the VA pays a monetary allowance instead. The allowance for qualifying interments in calendar year 2026 is $387.5Federal Register. Monetary Allowance for Outer Burial Receptacles The amount is recalculated each year based on the VA’s average procurement cost. If the family bought the container, the allowance goes to the family. If the cemetery provided it at no charge, the allowance goes to the state or tribal cemetery.6U.S. Department of Veterans Affairs. VA Expands Outer Burial Receptacles Benefit
Green Burial and Religious Exceptions
Some burials are done specifically without vaults, and cemeteries that host them build their policies around that.
Certified green burial grounds prohibit vaults, vault lids, concrete boxes, slabs, and liners of any kind.7Green Burial Council. GBC Cemetery Standard Documents The purpose is to let the body return to the earth through natural decomposition. Burials use a biodegradable shroud or an untreated wood casket placed directly in the soil, and ground stability is managed through deeper graves and natural landscaping instead of concrete.8Green Burial Council. Basic Tenets for Green Burial Cemeteries
Jewish burial custom calls for the body to rest in direct contact with the earth. The traditional practice uses a casket with a removable or open bottom. Concrete or stone can be acceptable if the material suits religious burial, but the container is typically placed in the grave before the casket is lowered rather than encasing it from above. Many conventional cemeteries accommodate this with a bottomless grave liner that meets the ground-stability requirement while preserving the religious obligation.
Islamic tradition holds that only the body and its shroud should go in the grave. A casket is acceptable for transport but is not meant to be buried unless local law or cemetery policy requires it, and vaults or liners are avoided when possible. Families arranging a Muslim burial in a conventional cemetery often negotiate a modified container or seek out cemeteries with a designated Muslim section that has adjusted its policies.
For both Jewish and Islamic burials in conventional cemeteries, raise the issue early with cemetery staff. Accommodations are easier to work out when the family gives documentation of the religious basis and enough time to plan the logistics. Some cemeteries already have standard accommodation policies for these situations.
