Buying hotel textiles: towel weight, sheet fabric and how many sets you need

Buy hotel textiles by specification, not by price: fabric and blend, weight in grams per square meter (GSM), finished size after washing, shrinkage and color-fastness limits, marking, and a wash test on a sample. Set counts follow from par stock. Industry practice commonly puts par stock for bedroom and bath textiles at around 3 to 4 sets per room; confirm the figure against your own laundry cycle and storage.

The invoice says 600 GSM and 300 thread count, the samples feel right in the supplier's showroom, and eight weeks later the towels come out of your own dryers stiff, short and two shades lighter. The order was never the problem; the missing document was a specification. This article shows you how to write one, what hotel towel GSM actually tells you, how to choose sheet fabric, how many sets to order, and how to run a wash test before you sign a large order.

What belongs in a hotel textile specification?#

A specification is a short written document that states what the item must be, how it will be measured, and what counts as a failure. A price request without one lets each supplier answer a different question.

Write the item, the fiber and blend as percentages, the construction (terry, percale, sateen, plain weave), the mass per unit area in GSM, and the finished dimensions before and after a defined number of washes. State acceptance limits, not adjectives: maximum shrinkage percentage after a set number of washes, minimum color-fastness grade, and the test method that will prove each one. Name the marking: a woven or printed hotel label, a color code per size or per floor, and where it sits so housekeeping can sort without reading.

Say how the goods will be packed and counted per carton, and who pays for the wash test sample. Keep a signed, sealed reference sample from the approved supplier; the delivered lot is compared against it, not against memory. Tie the specification to your purchasing paperwork so the receiving team checks the same lines the buyer wrote, in the same way as a full hotel purchasing and receiving procedure from order to storeroom.

Specification versus price request#

A price request asks "how much for 500 bath towels". A specification asks "how much for 500 bath towels, 100% cotton, 500 GSM measured per EN 12127, 70 by 140 centimeters after five washes, maximum shrinkage 4% per EN ISO 5077, color fastness to laundering at grade 4 minimum per EN ISO 105-C06, woven label, folded and packed twenty per carton". Suppliers can still compete on price, but they compete on the same item.

Expect suppliers to push back on test clauses. Some will say the tests are unnecessary, or that their cloth is well known. A supplier who cannot answer a shrinkage question in writing is telling you something useful, before you have paid for the lesson.

Who signs the specification#

The executive housekeeper signs the technical lines, because they will live with the result. Purchasing owns the commercial lines: packing, count, lead time, and the reference sample procedure. The general manager signs the total, not the cloth. One document, three signatures, no ambiguity about who decided what.

What does hotel towel GSM tell you, and what does it hide?#

GSM is the mass of one square meter of the cloth in grams, measured on a small sample under EN 12127. It tells you how much fiber sits in the fabric; it does not tell you how the towel absorbs, how fast it dries in your dryers, or how it will feel after fifty washes.

Weight and density are different things. A heavy towel with a loose pile can dry more slowly and shed more lint than a lighter, denser one. Drying time is a laundry question, not a textile question: a heavier towel lowers the load your dryers can turn per hour, so the same room count needs more drying capacity. This is one of the reasons to plan hotel laundry capacity before, not after, the textile order.

Size matters as much as weight. A large towel at a moderate GSM can weigh more per piece than a small towel at a high GSM, and piece weight is what your laundry and your cost per wash see. Ask for the piece weight in grams as well as the GSM, and ask what size that weight refers to.

Why hotel towels are soft, and why yours may not be#

Pile height and yarn type drive the hand feel. Softness after washing also depends on water hardness, detergent and softener program, and on how the item is dried and finished. A towel that felt luxurious in the showroom can feel like cardboard in a hard-water laundry with a flat dryer cycle. The showroom tells you about the cloth; only your laundry tells you about the towel.

For a bath towel, a hand towel and a face towel, write three separate specification lines. One line copied across three sizes is how mismatched sets happen. Pool and spa towels are a different purchase, not a cheaper version of the bath towel.

Weight, size and dryer capacity together#

Work the arithmetic per piece, not per square meter. For example, a 70 by 140 centimeter bath towel at 500 GSM has a piece weight of about 490 grams before finishing; a 100 by 180 centimeter sheet-bath towel at 400 GSM weighs about 720 grams. The lighter GSM item is the heavier wash. Multiply piece weight by pieces per room per day and you have dryer load per occupied room, which is the number that decides whether your laundry keeps up with your occupancy.

What linen do hotels use for sheets and duvet covers?#

The two common choices are 100% cotton or a cotton-polyester blend, in a plain percale or a smoother sateen weave. Whichever you pick, specify weight, shrinkage and color fastness rather than relying on thread count.

Cotton breathes and takes heat disinfection well but shrinks and creases. A polyester blend holds size and color longer and costs less per wash, at the cost of hand feel. For a property with heavy laundry throughput and price-sensitive guests, a blend is a rational choice; for a comfort-led property, cotton usually is. The decision is commercial, not technical: both can be specified well or badly.

Thread count in plain words#

Thread count means threads per square inch of fabric. It is a weak buying signal: multi-ply yarns can be counted more than once, so two suppliers can print different numbers for comparable cloth. Ask for fabric weight in GSM and for the yarn construction instead of a thread count headline. A 300 thread count sheet made of two-ply yarn and a 150 thread count sheet of the same single-ply yarn can be the same cloth with different labels.

Cotton against polycotton#

Shrinkage is the number that breaks a budget. A sheet that shrinks past the mattress depth is a write-off before it wears out, so specify residual shrinkage after a defined number of washes per EN ISO 5077. Duvet covers need a size that fits your duvet after washing, plus a closure that survives industrial handling; buttons and cheap zips fail before the fabric does.

Pillowcases take the most soiling and the most washing per guest night; specify them separately from sheets even when they come in one set. Color matters operationally: white shows stains and can be bleached, colored items hide stains but fade, and mixing the two in one wash load ruins both.

Why are pool and spa textiles a separate purchase?#

Pool, beach and spa textiles meet chlorine, sunscreen and sand, are washed in a different cycle, and are counted against a different par. Buying them on the bedroom order saves paperwork and costs money.

Chlorine and sunscreen attack cotton. Pool textiles are often specified in a blend or a heavier, more color-stable construction, and they are usually colored for a reason: the color hides the staining that pool chemicals cause. They are washed separately, often at a different temperature and with a different program, so they cannot share a wash classification with room linen.

They also leave the building. Beach towels walk to the pool and sometimes to the airport, so their loss rate is not the bedroom loss rate and their par is set higher. Mark pool textiles with a distinct color code so they never re-enter the bedroom circulation. Bathrobes and slippers sit in a third category: bathrobes are laundered per stay and wear out on a different curve from towels.

If you outsource laundry, confirm the pool textiles are inside the contract and priced separately. The same logic applies to the broader make-or-buy decision covered in in-house or outsourced laundry.

How many sets of linen does a hotel need?#

Multiply the pieces one occupied room needs by your par stock, then add a replacement allowance for yearly renewal and loss. TÜROB's August 2026 sector report gives both inputs as estimates you can start from.

Par stock is the number of complete sets you own per room: one on the bed, one in the wash or in transit, one on the shelf. The more sets, the more capital and the more storage. Common practice is around 3 to 4 sets per room for bedroom and bath textiles, and 4 to 5 sets for restaurant table linen. For example, a hotel with 100 rooms at 3.5 sets holds 350 bedroom sets; at 4 sets it holds 400. The right number depends on your laundry turnaround, your storage and how much capital you want tied up in linen.

These are sector estimates, not norms. A resort with a long season, an outside laundry and a beach club will run higher; a city hotel with fast turnaround may run lower.

Par stock in one paragraph#

Par is the multiplier between one room and your total order. A par of 3.5 means you own three and a half sets per room position: enough for one in use, one in the laundry pipeline, one on the shelf and a half set absorbing losses between orders. Higher par buys resilience against laundry delays and supplier lead times; lower par buys lower capital tied up in cloth. The right number depends on your laundry turnaround, your season length and your storage, which is the same logic explained in detail in hotel linen management: par levels, laundry flow and losses.

Turning the estimate into your own order#

For example, a 120-room hotel with two beds per room and a par of 3.5 needs 120 x 2 x 3.5 = 840 sheet positions before any replacement allowance. Apply the 30% yearly renewal estimate and the same hotel plans to replace roughly 250 sheets a year. The arithmetic is yours; the estimate only gives you a starting par.

Recount your own discards for three months before the next order. The real number is in your linen room, not in a report.

How do you run a wash test before a large order?#

Wash the sample the way your laundry will wash it, at least ten times, measuring the same properties before and after, against limits you wrote down before the first wash.

Ask every shortlisted supplier for the same item in the same size, and code each sample so the results cannot be mixed up. Measure and record before washing: length and width in centimeters, piece weight in grams, GSM if you can, color against a reference, and a photograph under fixed light. Wash in your own machine with your own program, detergent and water, not in a laboratory. EN ISO 6330 describes the domestic washing and drying procedures used for textile testing, and it is useful as a common reference, not as a copy of your laundry. EN ISO 15797, the industrial washing procedure used for workwear testing, is a laboratory method and does not tell an industrial launderer how to run its own process.

After ten washes, re-measure and compare against your limits: dimensional change per EN ISO 5077, color change and staining per EN ISO 105-C06, plus pilling, hand feel, edge wear and seam condition. Record the result on one sheet per sample and keep the washed sample; the washed piece is the only honest showroom. If a supplier cannot supply a sample or refuses a wash test, that is an answer.

What to measure and when#

Measure twice: once before the first wash, once after the tenth. Everything between is a wash log, not a measurement. The standards themselves are published by national standards bodies; the titles and scopes cited here follow the Estonian Centre for Standardisation and Accreditation catalogue (7 November 2026) (opens in a new tab), which lists the European adoptions of EN ISO 6330, EN ISO 5077, EN ISO 105-C06, EN 12127 and EN ISO 15797.

Setting the pass limit before you look at the result#

Write the pass limits on the specification before the first wash, and have them signed. If you write limits after seeing the results, you will write the results you got. A limit set in advance is a decision; a limit set afterwards is a description.

What should happen at delivery, marking and first wash?#

Count it, check it against the sealed sample and the specification, mark it, wash it once before it reaches a room, and record what you accepted.

Count cartons and pieces against the delivery note before signing, and open at least one carton per size to check the item against the reference sample. Check the label: fiber percentages, size, and the supplier's own reference, so a later reorder matches this lot. Mark before the first wash, while the goods are still clean and flat, using your color code per size and per area.

Wash the first batch before issuing it. New textiles can shrink, bleed color and shed lint, and it is better to discover that in the laundry than on a bed. Quarantine anything that fails the specification and record the rejection with photographs; a rejection that is not written down becomes a discount on the next order. Enter the accepted quantity into your stock records so the par calculation and the next order start from real numbers.

Plan the first order against your opening date with lead time for the wash test and for delivery, not only for production. Textile lead times belong in the same pre-opening timeline as every other cost line; see the pre-opening budget for a hotel.

What to do next#

Write the specification sheet first, with the test methods and the pass limits on it, then run a ten-wash test on samples from two or three suppliers before you place the order. The set count comes after that: take the TÜROB August 2026 estimate as a starting par, correct it with your own discard records, and let the wash test decide which cloth you are willing to own for the next three years.
