What size walk-in cooler do I need for a funeral home?
Size a funeral home walk-in cooler by peak simultaneous occupancy — peak caseload times holding time, plus surge headroom — not the average month. This guide gives a simple sizing method and recommended sizes by funeral-home profile.
Short answer: size a walk-in by your peak caseload and how long cases stay — not your average month. A quick method: take your busiest month’s cases, divide by 30, multiply by your typical holding days, then add 50 to 100 percent headroom for surges. Most single-location funeral homes land on a 6x8 or 10x12 walk-in; high-volume and group operations move to 14x16 or larger.
The cooler you regret is the one sized to a normal week. Here is how to size for the weeks that actually test you.

What size walk-in cooler do I need for a funeral home?
Right-sizing comes down to how many bodies you must hold at the same time, at the same time of year, with room to spare. That peak simultaneous occupancy — not your annual call volume — is the number a walk-in has to satisfy.
Start with three numbers
- — Peak monthly cases: your busiest month in a normal year, not the average.
- — Typical holding days: how long a case usually stays before service, release, or transfer — see how long a body can stay in a mortuary cooler.
- — Surge factor: the cushion for a bad stretch — flu season, a multi-casualty event, or a run of unclaimed cases.
A simple sizing method
Estimate peak simultaneous occupancy like this: (peak monthly cases ÷ 30) × typical holding days. That gives the average number on hand during your busy month. Then add 50 to 100 percent headroom for surges and airflow. The result is the number of storage positions your cooler must hold — which you then translate into a size using racking. Because capacity is set by racking, not floor space, a smaller box with multi-tier racks can meet the same target as a larger empty room.
Recommended size by funeral-home profile
- — Small firm, lower volume: an upright cooler or a 6x8 walk-in. If a full walk-in is more than you need, a 3-body upright or 4-body upright may be the better fit.
- — Busy single location: a 10x12, racked for density and turnover. A roll-in cooler helps where cot transfers are frequent.
- — High-volume or shared facility: a 14x16, with racks sized to peak occupancy.
- — Group operator, hospital, or medical examiner: a 10x20 or 10x25, often paired with vault-style units for individually accessible cases.
Do not forget peaks, growth, and oversized cases
Three things quietly push you to the next size up:
- — Surges: the cooler must absorb your worst week, not your typical one.
- — Growth: size for where your call volume is heading over the next several years, not just today.
- — Bariatric and oversized cases: these consume more than one standard position, so plan dedicated extra-wide capacity rather than letting one case eat two slots.
Practical constraints: space, power, and airflow
Beyond the body count, confirm the room can host the unit: floor space and ceiling height for racking, electrical capacity for the refrigeration system, and condenser placement. Leave clearance for airflow so a busy cooler still holds 36 to 39°F — see what temperature a mortuary cooler should be and how cold a morgue cooler gets. Once installed, tie in walk-in monitoring, a temperature alarm, and a power-failure alert through the HALO smart monitoring system. For loading and transfers, plan for quality first-call cots.

Frequently asked questions
What size walk-in cooler does a funeral home need?
Size to peak simultaneous occupancy: (peak monthly cases divided by 30) times typical holding days, plus 50 to 100 percent headroom. Most single locations land on a 6x8 or 10x12; high-volume operations use 14x16 or larger.
Should I size to my average or peak caseload?
Peak. A cooler sized to the average month overflows during surges. Size to your busiest expected period and add headroom.
Is a walk-in always better than upright coolers?
Not always. Lower-volume firms are often better served by upright coolers, which cost less and take less space. Walk-ins win on capacity and racked density.
How do I account for bariatric cases?
Plan dedicated extra-wide capacity. Oversized cases occupy more than one standard position, so building in extra-wide storage prevents one case from consuming two slots.
