No law requires you to buy a burial vault or grave liner, but many cemeteries require one so graves do not sink, according to the Federal Trade Commission funeral compliance guide. Grave liners typically run $500-$1,400 and burial vaults $900-$4,000, with a 2023 median vault charge of $1,695.
A burial vault is a lined and sealed outer box that holds the casket and resists water and soil pressure. A grave liner is an unlined concrete box that supports the soil above the casket but does not seal out water, according to Wilbert Burial Vault of Greenville citing National Concrete Burial Vault Association standards. Either type satisfies a cemetery rule against grave sinkage.

What is the difference?
A grave liner carries the weight of the soil after burial. It is simple concrete, without a lining or sealing cover. Its job is structural: keep the surface level. A burial vault adds a liner and a sealed cover.
It is built to resist water and soil intrusion around the casket. It costs more because of those materials and the seal. Neither option preserves the body. Neither vaults nor liners prevent eventual decomposition, according to the Funeral Consumers Alliance of Georgia. A seller may not claim a vault will keep water, dirt, or debris from reaching the casket.
Can a cemetery require one?
Yes. No state or local law forces families to buy an outer container, but cemeteries often set their own requirement. California regulators explain the same split: the law does not require vaults or liners, yet cemeteries may require them to keep ground from settling.
That rule applies to the grave, not to a brand. If the cemetery requires an outer container, a liner meets the sink-prevention need. You do not need a sealed vault unless you want one.

What do they cost?
The National Funeral Directors Association reported a $1,695 median vault charge in 2023, which raised a viewing-and-burial funeral median from $8,300 to $9,995 before cemetery plot and marker, according to NFDA data summarized in the Parting Stone funeral-cost analysis. That figure covers the vault alone, not the grave, opening and closing, or headstone.
Retail shopping shows a wide spread. Grave liners are commonly listed around $500-$1,400 and burial vaults around $900-$4,000, with Titan Casket estimating $1,400-$2,500 when billed through the cemetery or funeral home in its burial cost guide. Material, seal design, and who sells the container move the final bill.
How can you pay less?
Choose the liner when your only goal is meeting the cemetery rule. It provides the required ground support at the lower price.
Ask the cemetery for its container standards in writing, then compare liner and vault prices against those standards. Use your shopping rights before you look at models:.
- Get the outer-container price list before viewing containers.
- Compare the funeral home, cemetery, and outside sellers on the same size and material.
- Buy from the seller you prefer if the container meets cemetery standards; you need not buy from the cemetery itself, according to the Federal Trade Commission and California Cemetery and Funeral Bureau consumer purchase guide.
