A commercial laundry does not really buy towels. It buys wash cycles: the number of times a towel can go through a hot wash, a hard tumble and a fold before it is thin, grey or frayed enough to pull from circulation. Every other line on the spec sheet matters only because it moves that number. A supplier who quotes on GSM and price alone is answering a question the laundry did not ask.
These are the six things a laundry should get in writing before it signs a towel supplier, and how to check each one when the goods arrive.
1. A wash-life floor, stated as a number
Ask for the number of industrial wash cycles the towel is built to survive, and put it in the contract. For general hospitality towelling the floor should be at least 50 industrial cycles with acceptable weight and appearance. Healthcare routes, which wash hotter and more often, should specify 200 cycles.
A supplier who will not commit to a figure is telling you something. "Durable" and "hotel quality" cannot be measured or claimed against.
2. GSM measured the way you will measure it
GSM (grams per square metre) is the most quoted spec and the most easily shaded. Agree how it is measured: on a conditioned sample, after the first wash, with a stated tolerance (commonly ±5%). Then cut a swatch from your first delivery and weigh it yourself. If the number is short, every kilo you buy is short with it.
Laundries that buy by the kilo should care even more. A towel that is 8% under its stated GSM costs 8% more per usable piece than the quote suggests.
3. The yarn, named in full
Two towels at the same GSM can last very differently, and the reason is the yarn. Ask for combed, ring-spun cotton on anything that has to survive a commercial route. Carded or open-end yarn costs less up front, then pills and sheds sooner, and the lint ends up in your dryer filters as well as in the replacement budget.
If the yarn is not named on the quote, assume it is the cheapest option and price it accordingly. Our yarn terms guide explains each term.
4. Dye and colourfastness for your wash chemistry
White towels need to stay white and coloured ones need to stay their colour. Ask for reactive dyes on coloured goods and for colourfastness results to washing (ISO 105-C06 is the common reference). If your route uses chlorine bleach, say so up front, because a shade that survives a domestic wash can strip fast in hypochlorite.
5. Construction details that fail first
Towels rarely fail in the middle. They fail at the edges. Specify:
- Hems: double-stitched, with a stated stitch density, so they do not open after a few cycles.
- Selvedges: tightly woven, so they do not fray in the tumble.
- Shrinkage: a stated maximum after the first wash, so sizes stay consistent across the stock.
6. Consistency across reorders
A laundry runs stock in circulation for years and tops it up constantly. If each reorder comes back a slightly different weight, size or shade of white, mixed stock looks tired even when it is new. Ask the supplier how it holds specs across reorders: a retained approved sample, the same mill, and the same yarn count each time.
The spec at a glance
| What to specify | Minimum to ask for | How to check on delivery |
|---|---|---|
| Wash life | 50 industrial cycles (200 for healthcare) | Written in the contract; supplier test data |
| GSM | Stated value, ±5% tolerance | Weigh a cut swatch |
| Yarn | Combed, ring-spun cotton | Named on the quote and the packing list |
| Dye | Reactive dyes; ISO 105-C06 results | Test report; a wash test on one piece |
| Hems and selvedges | Double-stitched hem, tight selvedge | Visual check across a carton |
| Shrinkage | Stated maximum after first wash | Measure before and after one wash |
| Reorder consistency | Retained approved sample | Compare each reorder against it |
Price per kilo, honestly
Most laundries compare suppliers on price per kilo, and that is a reasonable starting point. But price per kilo divided by wash life is the number that decides the budget. A towel that costs 10% more per kilo and survives half as many cycles again is the cheaper towel. Cheap towels feel economical on the purchase order and expensive in replacement spend.
What we run
We supply commercial laundry towelling on combed, ring-spun cotton as standard, with GSM, shrinkage and colourfastness specified on the quote rather than left implied. Our terry towel programmes are built to the wash-life floors above, and we hold an approved sample against every reorder.
Send us your route: wash temperature, chemistry and cycles per week. We will spec the towel to it before you commit to a sample.
Frequently asked
- How many washes should a commercial towel last?
- For general hospitality laundry, specify at least 50 industrial wash cycles with acceptable weight and appearance. Healthcare routes, which wash hotter and more often, should specify 200 cycles. Put the figure in the contract. Words like "durable" or "hotel quality" cannot be measured or claimed against.
- Should a laundry buy towels by GSM or by price per kilo?
- Use both, then go one step further: divide the price per kilo by the expected wash life. A slightly dearer towel that survives far more cycles costs less per use. GSM is still worth checking, because a towel under its stated weight raises your real cost per piece.
- How can a laundry check towel quality on delivery?
- Weigh a cut swatch to confirm GSM, check hems and selvedges across a carton, measure a piece before and after one wash for shrinkage, and compare the delivery against your retained approved sample. Those four checks catch most quality slippage before it goes into circulation.
