A single wall cup with a separate sleeve is almost always cheaper than a double wall cup, and almost always more work at the counter. That is the whole trade, and which side you land on depends on how many hot drinks you sell and how much you care about the cup being a brand surface.
Here is how the three hot cup constructions actually compare.
Quick answers
Single wall. One layer of poly-coated board. Cheapest. Too hot to hold above about 140F without a sleeve.
Single wall plus sleeve. The most common setup in North America. Two SKUs, two minimums, two artworks, lowest total cost at volume.
Double wall. Two bonded layers with an air gap. Holds comfortably with no sleeve. Costs more per cup, one SKU.
Ripple wall. A corrugated outer layer. Best insulation of the three, most texture, hardest surface to print fine detail on.
Single wall
A single wall cup is one layer of paperboard with a food-grade polyethylene coating on the inside. It is the baseline. Everything else is priced against it.
It is the cheapest cup you can print, it stacks tightest, and it takes the crispest print because the outside is smooth uncoated or lightly coated board.
The problem is heat. Filled with coffee at service temperature, a single wall cup is uncomfortable to hold within a few seconds. Customers double-cup, which costs you two cups and looks careless, or they take a sleeve.
Use it if: you serve a lot of hot drinks, you already buy sleeves, and you want the lowest cost per drink.
Single wall plus sleeve
This is what most cafes end up doing, and the reason is arithmetic rather than aesthetics.
A sleeve is a small piece of corrugated board. It costs a fraction of what the insulation built into a double wall cup costs. You also do not put a sleeve on every drink. Iced drinks never need one, and a customer taking a cup to a table two feet away will often wave it off. In practice a busy cafe uses sleeves on maybe 60 to 70 percent of hot drinks, so you are paying for insulation only when it is actually needed.
There is a branding argument too. A sleeve is a bigger, flatter, better print surface than the curved side of a cup. If you want a logo that reads across a room, the sleeve is a better place for it than the cup.
The costs are real though. It is a second SKU with its own minimum. Custom printed sleeves run at a minimum of 5,000, against 10,000 per size for cups, so the sleeve minimum is easier to hit. But it is still a separate order, separate artwork, and a separate thing to run out of on a Saturday.
Sleeves are printed with water-based inks, which matters because the sleeve is the part of the package a customer actually grips.
Use it if: volume is high enough that per-cup cost matters, or you want a large clean print surface.
Double wall
A double wall cup bonds a second layer of board around the outside, leaving a thin air gap. The air does the insulating.
One SKU, no sleeve to stock, nothing for a barista to remember, and a cup that feels more substantial in the hand. For a cafe positioned above the commodity end of the market, that hand-feel is most of the argument.
It costs more per cup than a single wall, and more than most single-wall-plus-sleeve combinations once you account for the fact that you do not sleeve every drink.
Two practical notes people miss. A double wall cup is wider than a single wall cup of the same volume, so check your cup dispensers before you switch. And double wall cups do not nest as tightly, so the same shelf holds fewer of them.
Use it if: you are a lower-volume, higher-ticket operation, or you have decided the cup is part of the brand and you want it clean.
Ripple wall
Ripple wall uses a corrugated outer layer instead of a smooth one. It is essentially a sleeve permanently bonded to the cup.
It insulates better than a standard double wall, and it has an obvious tactile quality that reads as "premium" to some customers and "disposable" to others.
The catch is print. The corrugation means the printed surface is not flat. Large bold marks work. Fine serif type, thin rules and small text do not reproduce cleanly. If your brand is a wordmark in a light weight, ripple will disappoint you.
Use it if: insulation is the priority and your logo is bold and simple.
What this costs you in practice
Run the numbers against your own volume rather than trusting a rule of thumb.
Take your hot drinks per week. Multiply by 52. That is your annual cup need per size. Custom printing runs at 10,000 per size minimum, so a cafe doing 200 hot drinks a week across one size is carrying nearly a year of stock on a single order. At that volume the per-cup difference between constructions is small in absolute dollars, and the operational simplicity of double wall probably wins.
A cafe doing 1,500 hot drinks a week is a different business. There, the gap between single-wall-plus-sleeve and double wall is real money, and the sleeve setup starts to pay for its own complexity.
Pricing on both comes back at two quantity breaks, so you can see what the next tier does before you decide. Quotes land in two business days.
Food contact and paperwork
All of these are food contact items. Paperboard and the poly coating on it fall under FDA 21 CFR 176 and 177. Ask for the documentation in writing before you place an order.

If you have not settled your size range yet, custom cup sizes explained covers what 8oz, 12oz and 16oz actually measure and why rim diameter matters more than ounces.
And if the 10,000 per size minimum is the thing standing in your way, how many custom cups a cafe actually needs works through whether the number makes sense for your volume.
