How Many Towels Does a Pilates Reformer Studio Need? How to Calculate Your Stock

It's one of the questions boutique studios ask us most: how many towels do you actually need to run smoothly? Almost everyone starts by buying “one per reformer” and, two weeks later, finds it doesn't work: some towels are in the wash, some are drying, one went home with a client by mistake, and the 7pm class is still waiting. In this guide we share a simple formula to calculate the real towel stock for your Reformer Pilates studio, with enough margin that you're never running on empty.

Why “one towel per reformer” is never enough

The miscalculation comes from thinking of the towel as a fixed part of the equipment, like the footbar or the springs. But a direct-contact towel is a rotating consumable: it leaves circulation the moment class ends and doesn't come back until it's washed and completely dry.

In a studio with 8 reformers and 6 classes a day, every space generates 6 used towels per day. With only 8 towels you'd be washing between classes, which is impossible to sustain. What you need to cover isn't one class: it's one full wash-and-dry cycle.

The formula: spaces × classes per day × cycle days + margin

Here's the calculation we recommend, step by step:

1. Spaces in the studio. The number of reformers in use at the same time.
2. Classes per day. Use your busiest day of the week, not the average. Stock is sized for the peak, not the mean.
3. Laundry cycle in days. How long it takes a towel to become available again: washing + drying + folding. If you wash daily and air-dry overnight, your cycle is 1 to 2 days. If you wash every other day, it's 2 to 3.
4. A safety margin of 20-30%. This covers the unexpected: a stained towel, a client who takes one home, a broken washing machine, an extra class, a towel that's due for replacement.

A worked example. A studio with 8 spaces, 6 classes on its busiest day and a 2-day laundry cycle: 8 × 6 × 2 = 96 towels; plus a 25% margin = 120 towels. If that same studio washes daily and dries quickly (a 1-day cycle), it drops to 8 × 6 × 1 = 48, plus margin = 60 towels.

The conclusion is clear: your washing and drying capacity shapes your stock as much as the number of spaces does. Sometimes it pays more to fix the laundry process than to buy twice as many towels.

The factor most people forget: drying time

The variable that throws the numbers off is almost always drying. A rubber-grip towel should be air-dried, never tumble-dried, so it keeps its properties. If you hang it folded, in a room with no ventilation or bunched up against other towels, the cycle stretches from overnight to a full day, and your required stock doubles without you deciding it.

It's worth setting up a drying rack with real spacing between towels and some air circulation. We cover it in detail in how to air-dry a Pilates towel, and the same logic scales up to a studio.

Three service models (and the stock each one needs)

• The studio provides a towel at every space. This feels the most premium and demands the most stock: apply the full formula. It's common in boutique studios with higher membership fees.
• Each client brings their own. This reduces studio stock to a courtesy pool (10 to 20 units for anyone who forgets or comes for a trial class). It works best if you sell the towel at reception, so clients use the same format the studio recommends. On why a personal towel makes sense, we go deeper here: why every client should bring their own towel.
• A mixed model. The studio covers trial classes and premium packages, and everyone else brings their own. Apply the formula only to the classes you cover, then add the courtesy pool.

Replacement: when it's time to renew part of your stock

Studio towels don't all wear out at once: they degrade in batches, according to how many washes they've had. Review the batch quarterly and set aside any units showing patchy grip loss, frayed edges, a smell that survives washing, or uneven fading.

A good practice is renewing 10-20% of your stock each year and always buying the same model, so the studio looks consistent and every client gets the same experience. This is where choosing a supplier with product continuity and single-unit reordering really shows; we cover it in how to choose an accessories supplier for your Pilates studio.

A quick checklist before you order

• Did you calculate using your busiest day rather than the average?
• Does your real laundry cycle include full drying, not just washing?
• Have you added a 20-30% margin?
• Have you planned a courtesy pool for trial classes?
• Does your chosen model grip on both sides, so nobody has to reposition it between exercises?
• Will you be able to reorder single units months from now without switching model?
