3 oz Wax-Coated Cups vs 5 oz Cold Cups: Med Cart or Hydration?
3 oz wax-coated cups vs 5 oz plastic cold cups: graduated med-cart cup vs bulk hydration cup, per-cup cost, case packs, and which to stock where.
If you stock disposable cups for both a med cart and a hydration station, sooner or later your purchasing lead lands on the 3 oz wax-coated cups vs 5 oz cold cups question — not "which cup is better," but which of these two everyday SKUs belongs at which station, in what case quantity, at what cost per cup. Both are single-use, both ship by the case, and on a shelf they can look interchangeable. They aren't. One is a rigid wax-coated paper cup built for the med pass, the other a clear plastic cup built for bulk cold hydration, and they diverge on material, capacity, case pack, and per-cup cost in ways that decide where each one goes. This guide compares the two SKUs we keep stocked and how facilities typically split them.
This is a procurement comparison, not a clinical guide. Nothing here is about medication itself — these are the cups, not the contents. The question we answer is the inventory question: which disposable cup goes on which station, in what case size, at what cost per cup.
What the two SKUs actually are
The material and capacity gap is what drives every downstream stocking decision. Both are disposable, single-use cups sold by the case. After that they answer different questions.
The 3 oz Wax-Coated Cup (CUP-3OZ-WAX) is a rigid, graduated white paper cup with a wax-coated interior, built for medication dispensing, pill-taking, and the water-to-swallow-with that goes alongside it on a med cart. The wax coating is the procurement-relevant feature: it gives the paper wall structural rigidity so the cup holds its shape and resists leaking during a cold pour, and the cup is sized at 3 oz — enough water to take pills without overfilling. It ships 5,000 to a case, organized as 50 sleeves of 100 for easy med-cart restocking, and carries SFI, CMA, and green-product certifications for facilities that track that on the paper side. This is the cup for the med pass, pill rounds, and any cart where you want a sturdy paper cup rather than plastic.
The 5 oz Translucent Plastic Cold Cup (CUP-5OZ-COLD) is a clear, flat-bottom plastic cup for cold beverages. The flat bottom and clear body are the features that matter: it stands on a tray, can be carried back to a chair or bed, and lets staff read fill level at a glance. It ships 2,500 to a case at a 5 oz capacity, and it's built for water service, juice, and patient hydration rather than the cart. This is the cup for cafeteria beverage stations, tray service, and hallway hydration points where a drink leaves the dispenser and travels.
So on the floor they answer different questions. The wax cup is the med-cart, take-your-pills cup. The cold cup is the carry-it-with-me hydration cup.
Per-cup price, side by side
Because the two ship in different case quantities, the only honest comparison is cost per cup, not cost per case. Pulled from our live catalog as of this week:
| Spec | 3 oz Wax-Coated Cup | 5 oz Plastic Cold Cup |
|---|---|---|
| SKU | CUP-3OZ-WAX | CUP-5OZ-COLD |
| Material | Wax-coated paper | Plastic (translucent) |
| Capacity | 3 oz | 5 oz |
| Design | Graduated, rigid wall | Flat-bottom, clear |
| Case pack | 5,000 / case | 2,500 / case |
| Case price | $375.00 | $85.00 |
| Per-cup cost | ~$0.075 (7.5¢) | ~$0.034 (3.4¢) |
| Primary use | Med pass, pill rounds | Cold hydration, tray service |
| Best for | Med carts | Cafeteria, hydration stations |
The two are not priced to compete for the same job. The 5 oz cold cup lands at about 3.4¢ per cup, roughly 55% cheaper per pour than the 3 oz wax cup at 7.5¢, and it holds more. If you read only the per-cup line, the cold cup wins outright. But the price gap is the point, not a problem: the wax cup costs more because it's a rigid, graduated paper cup spec'd for the med cart, and the cold cup is cheaper because it's a plain plastic hydration cup. Standardizing on the cheaper cup for med pass trades the wrong way — you'd be putting a 5 oz plastic hydration cup on a cart that wants a 3 oz graduated paper cup.
Why the wax cup costs more — and when that's worth it
Three things put the 3 oz wax cup above the cold cup on price per unit. It's a graduated medical-style cup rather than a generic beverage cup, it's wax-coated paper rather than commodity plastic, and it carries SFI/CMA/green certifications that the plain cold cup doesn't. For a med cart, those are the features you're buying: a sturdy paper cup that holds its shape under a cold pour, a graduated profile suited to the pass, and a paper rather than plastic footprint where facilities prefer it.
For a hydration station, none of those features earns its keep. Residents filling a cup at a water cooler don't need graduation marks or a certified paper wall — they need a cheap, larger cup that stands on a table. That's exactly where the 5 oz cold cup's lower cost and bigger capacity pay off, and where paying 7.5¢ for a med-grade wax cup would be overspending on the wrong station.
How volume splits between the two SKUs
A typical 60-bed facility running scheduled med passes plus all-day hydration will burn cold cups far faster than wax cups. Med-pass pulls are bounded by census and pass count — a fixed number of residents, a fixed number of rounds a day — while hydration runs continuously across residents, staff, and visitors.
A rough split we see at the facility level for a 60-bed site:
| Use | Monthly volume (est.) | SKU |
|---|---|---|
| Scheduled med passes (water-with-pills) | 3,000–6,000 cups | CUP-3OZ-WAX |
| PRN / between-pass medication water | 1,000–2,000 cups | CUP-3OZ-WAX |
| Cafeteria + tray-service beverages | 4,000–8,000 cups | CUP-5OZ-COLD |
| Hallway + bedside hydration | 4,000–9,000 cups | CUP-5OZ-COLD |
The implication for reorder cadence: the wax cup is the steady, census-driven cart line, and the cold cup is the high-volume hydration line. Most facilities at 60-bed scale hold one to two cases of each, with the cold cup reordered more often because hydration burn outpaces the pass.
Stocking math: how many cases per quarter
The math below is a starting point for sizing a standing order. Adjust for your own census, number of daily passes, and how much hydration runs outside meals, but it gets most sites within one case of right on the first reorder.
| Census | Wax cups / month | Wax cases / quarter | Cold cups / month | Cold cases / quarter |
|---|---|---|---|---|
| 30 residents | ~2,500 | ~2 cases | ~4,000 | ~5 cases |
| 60 residents | ~5,000 | ~3 cases | ~8,000 | ~10 cases |
| 120 residents | ~10,000 | ~6 cases | ~16,000 | ~20 cases |
| 200+ (corrections) | ~18,000+ | ~11+ cases | ~28,000+ | ~34+ cases |
Two things move these numbers. Wax-cup burn tracks census and pass count almost linearly — more residents and more rounds, more cups — so it's the predictable line to forecast. Cold-cup burn swings with season and service model: summer pushes hydration up, and facilities that lean on pitcher-and-glass tray service instead of disposable cups push the cold-cup line down. Because the cold cup ships in the smaller 2,500 case, the same monthly volume turns into more cases per quarter than the wax cup's 5,000-count case.
3 oz wax-coated cups vs 5 oz cold cups: which to default to
There's no single default cup here; there's a default per station.
Standardize on the 3 oz wax-coated cup (CUP-3OZ-WAX) for the med cart and pill rounds. The graduated profile, rigid wax-coated paper wall, and 50-sleeve case packing are built for the pass, and the 5,000-count case keeps cart restock simple. This is the cup to buy for medication water, not the cheapest cup on the catalog.
Standardize on the 5 oz plastic cold cup (CUP-5OZ-COLD) for cold hydration that leaves the dispenser — cafeteria beverage service, meal trays, bedside and hallway water. The flat base, clear body, larger capacity, and lower cost per cup are exactly what high-volume hydration wants, and none of the med-cart features you'd pay extra for apply there.
If your purchasing lead wants to collapse both into one SKU to simplify ordering, neither substitution works cleanly: the 5 oz cold cup is the wrong cup for the cart (plastic, ungraduated, larger than a pill pour needs), and the 3 oz wax cup is the expensive choice for bulk hydration (more cost per cup, smaller pour). Stocking both, matched to station, is cheaper and cleaner than forcing one cup to do both jobs.

FAQ
Why is the 3 oz wax cup more expensive per cup than the 5 oz cold cup? Different product class. The wax cup is a graduated, wax-coated paper med-cart cup with SFI/CMA/green certifications, shipping 5,000 to a case at $375 (about 7.5¢ each). The cold cup is a plain translucent plastic hydration cup shipping 2,500 to a case at $85 (about 3.4¢ each). You're paying for the med-grade build on the wax cup, not a quality downgrade on the cold cup.
Can the 5 oz cold cup replace the wax cup on a med cart? Not ideally. It's plastic rather than paper, ungraduated, and larger than a pill-water pour needs. Facilities that want a graduated paper cup on the cart should stock the 3 oz wax cup for that role and keep the cold cup for hydration.
Is 3 oz enough water for a med pass? For taking pills, yes — 3 oz is a standard pill-water pour, enough to swallow medication without overfilling a cup that sits on a crowded cart. If a resident needs a fuller drink at the bedside, that's a hydration cup job, where the 5 oz cold cup fits.
How long does one case last at a 60-bed facility? At roughly 5,000 wax cups a month for a 60-bed site, a 5,000-count case covers about a month, putting wax-cup reorder near three cases a quarter. Cold-cup burn is higher and ships in a smaller 2,500-count case, so it's typically reordered more often — closer to ten cases a quarter at the same census.
Are these the same as the souffle cups used for the medication itself? No. The 3 oz wax cup is the water cup that goes with the pills; the smaller 0.75 oz souffle and portion cups hold the medication. They're separate SKUs with different sizes and case packs.
