Washroom Supplies: Jumbo vs Conventional vs Interleaved
Washroom systems: jumbo, conventional or interleaved
Choosing toilet paper for a workplace looks like choosing toilet paper. It isn't. You are choosing a dispenser system, and the dispenser will still be on the wall in five years dictating what you are allowed to buy. Getting this decision right once is worth more than any amount of shopping around afterwards.
The short answer. Compare on sheets per roll, never roll count — a “48 roll” carton can hold less paper than a “36 roll” one. And decide the dispenser first, because the dispenser locks in the roll format for as long as it stays on the wall.
The three formats
| Format | What it is | Best for |
|---|---|---|
| Conventional | The household-size roll. Fits standard holders and most home-style dispensers. | Small offices, guest washrooms, anywhere the look matters |
| Jumbo / mini jumbo | A much larger-diameter roll needing its own dispenser. | High-traffic sites — fewer refills, less running out |
| Interleaved | Flat folded sheets in a stack, dispensed one at a time. | Controlling usage; sites where roll theft is an issue |
They are not interchangeable. A jumbo roll will not fit a conventional holder and interleaved sheets need a completely different dispenser again. Whichever you pick, you are picking for the life of the fittings.
Sheets per roll, not roll count
This is where washroom buying goes wrong most often. Cartons are advertised on roll count because it is the bigger, friendlier number — but rolls vary enormously in sheets. A carton of 48 short rolls can contain less usable paper than a carton of 36 long ones, at a higher price.
The comparison that works:
- Find sheets per roll on the pack (it is always stated, sometimes in small print).
- Multiply by rolls per carton to get sheets per carton.
- Divide the carton price by that number.
You now have a cost per sheet, which is the only figure that compares like with like across brands, ply counts and roll formats. Do this once for the two or three products you are choosing between and the decision usually makes itself.
The same logic applies to hand towels: compare on sheets or metres per carton, not on pack count.
Choosing the ply
- 1 ply — highest sheet counts and lowest cost per sheet. Suits very high-traffic sites where volume beats feel. The catch: people compensate by pulling more, which erodes some of the saving.
- 2 ply — the commercial default, and the right answer for most workplaces.
- 3 ply — reads as premium. Worth it in client-facing and guest washrooms; hard to justify on a factory floor.
Ply is genuinely about perception as much as performance. In a washroom your customers use, it is part of how they judge the business — which is a legitimate reason to spend more there and less elsewhere.
The dispenser is the real decision
Two things follow from putting a dispenser on a wall.
You have chosen a format for years. Changing from jumbo to conventional later means replacing every dispenser in the building, not just changing an order line. Which is why it is worth deliberately deciding rather than inheriting whatever the previous tenant left.
Some systems are proprietary and some are not. Certain manufacturers supply dispensers on the understanding that you buy their consumables — sometimes free or heavily discounted up front, which is a real saving as long as you are comfortable with the lock-in. Generic dispensers cost more initially and let you buy anyone's stock. Neither is wrong; going in without knowing which one you have chosen is.
Ask before you fit: can this dispenser take other brands' refills, and what does a replacement dispenser cost if it breaks?
Practical fitting notes
- Fit a second dispenser or a spare-roll holder in each cubicle. Running out mid-use is the complaint that generates facilities tickets.
- Lockable dispensers pay for themselves anywhere the public has access.
- Match the dispenser to the traffic, not the room size. A small but constantly-used washroom needs jumbo more than a large quiet one does.
Hand towels — the same logic again
The formats mirror the toilet paper decision:
| Format | How it works | Notes |
|---|---|---|
| Interleaved / slimfold | Flat folded, one sheet at a time | Most controlled usage; best hygiene since only the taken sheet is touched |
| Roll towel | Continuous roll, hand or auto-cut | Fewer refills; auto-cut units control length |
| Centrefeed | Pulled from the middle of the roll | Versatile — also used in kitchens and workshops |
Interleaved wins on hygiene and on controlling consumption. Roll systems win on refill frequency. In a washroom with heavy peak traffic — a school, a stadium, a busy office at lunchtime — refill frequency is usually the thing that actually causes problems.
Soap: cartridge or bulk fill
The same lock-in question in a different form. Cartridge systems seal the soap in a sealed pack with its own pump — more hygienic, no topping-up contamination, and a fresh pump each refill — but tied to that manufacturer's dispenser. Bulk-fill dispensers take any soap from a drum and cost less per litre, at the price of a pump that eventually clogs and a refilling job someone has to do properly.
For food handling, healthcare and childcare, cartridge systems are generally the safer specification. For a general office, bulk fill is usually the cheaper sensible option.
Working out what you actually need
A rough method that beats guessing: take your headcount, multiply by the number of days a week the site operates, and track one month's actual consumption before committing to a standing order. Real usage varies enormously with the type of site — a warehouse and a call centre with the same headcount consume very differently — and no rule of thumb beats a month of your own data.
Then set the order slightly above that, because the cost of running out is a facilities complaint and the cost of over-ordering is a shelf.
This guide covers commercial washroom formats and purchasing method. Sheet counts, roll dimensions and dispenser compatibility vary by manufacturer — check the specification for the specific product and dispenser before committing to a system. General information for buying purposes only.
