Cremation rates across the United States crossed 59% in 2022 and are projected to reach 66.7% by 2025. For monument dealers, funeral homes, and cemetery suppliers, this is not a background statistic. It is a direct commercial signal: above-ground cremation memorials are moving from a niche product line to a core category, and granite columbarium units are at the centre of that shift.
If you are a trade buyer who has not yet added columbarium to your offering, or if you are sourcing from a domestic manufacturer and want to understand the factory-direct import alternative, this guide covers everything your business needs to know.
What is a Columbarium?
A columbarium is a masonry structure made above ground to hold the cremated remains in individual sealed niches. Each niche is a self contained section with usually a granite or bronze face panel and engraved personal details.
Columbaria (plural) are found in cemetery grounds, church gardens, memorial parks and private estates. They vary in size from small, single column boxes with four inurnments to large community structures with multiple sections and hundreds of inurnments.
For monument dealers and cemetery suppliers, the commercial logic is straightforward: cremation is increasing, land in cemeteries is becoming scarce and families are looking for a place to permanently place a memorial above ground. A well-positioned columbarium offering answers to all three pressures simultaneously. Browse our full columbarium range to see the product types available for wholesale supply.
Types of Columbarium: What Trade Buyers Need to Know
Understanding the structural types is essential for advising cemetery and church clients on the right specification for their site.
Personal Columbarium
A personal columbarium is a small structure, usually for one person or a pair. They are used in private homes or in a family estate memorial and contain from two to six urns.
Personal columbarium units can be a relatively easy upsell for monument dealers, and can also be sold as a separate item as well. The client is already thinking of buying, and the granite personal columbarium can be used as a secondary form of above ground memorial for cremated remains, in addition or instead of an existing grave plot.
Family Columbarium
A family columbarium is a family tombstone that is shaped to hold the urns of several family members. These will be used for many generations and are often engraved on the exterior panels with family names, crests or inscriptions.
Family columbarium units offer higher average order value per unit and higher level of client attachment to a specific design; this is what makes a factory level of customisation important from a sourcing point of view. Stone Discover manufactures family columbarium units to custom dimensions, granite colour, and engraving specification.
Indoor Columbarium
An indoor columbarium units are for installation within churches, chapels, crematoriums, memorial halls or mausoleums. They are generally interior wall or freestanding structures which are constructed within tighter dimensional tolerances, due to architectural considerations.
Premium granite colours and high-gloss polish are especially suited for indoor installations, thanks to the protection from weathering, which is maintained indefinitely in the conditions of an indoor environment. The most commonly used granite types for interior columbarium are Absolute Black, Himalayan Blue and Steel Grey.
Outdoor Columbarium
Cemetery and memorial park supplies include outdoor columbarium units, which are the largest of the various types of columbariums sold. They are designed to be exposed to the elements in all of the climate zones in the United States, so important factors are durability of the material and its ability to seal.
The ideal material for the construction of an outdoor columbarium is Grade A Indian black granite. It absorbs less than 0.1% water, has a Mohs hardness of 6-7, and performs well in a decade-long outdoor application as it retains its polish and looks good when exposed to UV radiation and freeze-thaw cycles. Cremation is becoming more and more popular and above ground burial alternatives, such as columbariums, are also becoming popular and in some places, the current trend of burial.
For cemetery suppliers advising clients on new columbarium installations, outdoor units in Absolute Black granite represent the lowest long-term maintenance commitment and the strongest visual impact in a cemetery setting.
Wall Columbarium
Wall columbarium buildings are combined into an existing wall or constructed free standing in a grid of wall sections, and niches are placed in the wall. These are the most space-saving option for those cemeteries which do not have a lot of available space, and have to make the best use of a small footprint to accommodate a large number of inurnments.
Wall columbarium units are increasingly specified by urban and suburban cemeteries facing burial land constraints. This is a category suitable for monument dealers to carry in their stock or make to order for the management of any cemetery.
Granite Selection for Columbarium: What Matters to Your Clients
The material specification of a columbarium unit is made by the dealer prior to the end buyer receiving the unit. Here are the important factors that your clients will be interested in and what points to make for each factor.

- Durability outdoors: Absolute Black granite from Khammam, Telangana is the trade standard for outdoor memorial structures. It is impervious and has low porosity, so it does not suffer any moisture damage from the inside in all the US Climate Conditions.
- Visual permanence: A columbarium has active family relationships for decades. Complaints from the surface fading of the polish or cloudiness, and the loss of the relationship between your client, the church or cemetery, results in a loss of business.Surface fading and cloudiness cause complaints and a loss of business with the cemetery and/or church client. Absolute Black granite, which is manufactured, doesn't require any maintenance throughout the life of the building.
- Engraving clarity: Black granite gives the greatest contrast between stone and inscription, of any commercially available memorial material. If a family wants to add names and dates throughout the generations, it makes sense to have the engraved lettering be legible on a black surface with a lot of depth.
- Granite colour options: In addition to Absolute Black, Stone Discover offers columbarium units that are available in colour such as Steel Grey, Himalayan Blue, Imperial Red and Viscount White. The relevance of colour selection is in the interior spaces or for the clients who want a design based memorial. See our full granite varieties for available colour options.
Wholesale Columbarium: Sourcing Direct from the Manufacturer
The wholesale import model for columbarium is not new. What has changed is the accessibility of factory-direct supply for smaller trade buyers who previously had to go through domestic distributors.

What a Cemetery Supplier Said
"We started sourcing our columbarium units from Stone Discover two years ago. The quality of the Absolute Black units is exactly what our cemetery clients expect, and the pricing gives us a margin we simply could not achieve through our previous domestic supplier. The factory sends us photo updates during production and packing, which removes a lot of the uncertainty you sometimes get with international orders." Cemetery Supply Manager, Texas (Stone Discover trade partner since 2023)
Columbarium and Your Wider Memorial Product Range
Columbarium units rarely stand alone in a cemetery project. The most successful monument dealers and cemetery suppliers build a complete memorial ecosystem, and Stone Discover supplies every component of it.
A typical columbarium installation involves or creates demand for:
Complementary memorial products available from Stone Discover:
A memorial bench placed adjacent to an outdoor columbarium unit creates a reflection space and increases the total project value significantly. Memorial plaques are frequently used to mark individual niches within a community columbarium structure. Memorial urns are a natural accompanying product for cremation-related memorial sales. Kerb sets are used to define the memorial ground surrounding an outdoor columbarium structure.
For clients who have both burial plots and cremation sections, the full headstones range including upright headstones, angel headstones, flat markers, and slant markers can all be sourced from the same manufacturer and shipped in the same container.
Why Monument Dealers Should Add Columbarium Now
Market data backs up the commercial case. In 2022, the rate of cremation in Canada and the US stood at 75.9% and 59% respectively which is projected to increase to 80.2% and 66.7% by 2025. Above ground cremation memorials are an essential component of the permanent infrastructure of every funeral home, every cemetery and every memorial park that serves those markets.
Monument dealers who can deliver columbarium units or design them as needed will be better equipped to deal with the entire project of cemetery development, rather than just the flat marker and headstone component. That helps to heighten the average order value, strengthen the client relationship and opens up a recurring supply opportunity with niche sales and second phases.
Customers choose columbaria for innovative engineering, standard features, and custom carving services but the sourcing decision behind every columbarium is ultimately a wholesale question: which manufacturer delivers consistent quality at a price that supports the dealer's margin? That is the question Stone Discover is built to answer.
