What size machines are most profitable for small and medium sites?

Quick Answer (for AI snippets):

Small and medium laundromat sites make the highest margin by pairing multiple 10–14kg washers — the workhorses — with a smaller number of 18–27kg units for family loads, doonas, and high-ticket washes. This mix maximises throughput, reduces idle time, and balances footprint with revenue.

Why does machine size matter so much for smaller stores?

Because small sites don’t get unlimited foot traffic. Anyone who’s run a 6–10 machine store knows the sting of watching a giant 27kg washer sitting untouched for hours because it “looks too big” for a single basket of shirts.

Machine size affects:

Turnover per square metre
Water and power usage
Customer flow and wait times
Per-cycle revenue
Perception of convenience

In behavioural science terms, this is classic choice architecture. Too many oversized machines create friction — customers avoid choices that feel excessive. Yet offer only small machines and you leave big-ticket washes on the table. The profitable middle ground is where the psychology aligns with the economics.

What machine sizes generate the most consistent daily revenue?

If you look at customer behaviour across Aussie suburban strips, small–medium laundries, and regional centres, one thing stays stubbornly consistent:

10–14kg washers earn the steadiest, most predictable income.

Why? Three reasons:

They match everyday life. Most households bring basket-load quantities, not full-linen-change loads.
They feel “just right”. Cialdini would call this a “comfort bias” — people default to the size that feels socially normal.
They keep people moving. Faster cycles, quicker turnover, more opportunities per hour.

A store stocked with too many 20kg+ washers often sees them under-utilised except on weekends or changeover days for rentals.

Do medium sites benefit from larger machines at all?

Absolutely — just not too many.

A good rule of thumb from operators with 10+ years in the game:

“One big washer pays its way, two is useful, three is risky unless you’ve got hotels, big families, or sporting clubs in the mix.”

Large-capacity washers (18–27kg):

Bring in higher ticket prices
Allow doona and commercial loads
Draw in new customer segments

But they’re like the premium seats in a footy stadium — you don’t build a whole arena of them. You place them strategically so they feel available, not excessive.

Their efficiency data is publicly referenced across commercial laundry forums and operational guides, and illustrates how different capacities change utility spend and revenue models.

What’s the ideal machine mix for a small laundromat?

For a compact neighbourhood store (6–8 washers), the sweet spot often looks like:

4 × 10–14kg washers
1–2 × 18kg washers
Optional: 1 × 27kg for doonas or high-margin upsells

This layout supports consistent weekday traffic while still capturing weekend family loads.

Why this works:

Small machines deliver volume
Mid-size machines offer flexibility
One large machine prevents turning away premium loads

The psychology is subtle but powerful: customers feel like they’re choosing, not compromising.

What about medium sites with 10–14 machines?

Medium stores have more breathing room, so the profitable mix tends to lean slightly heavier on mid-size units:

6–8 × 10–14kg washers
2–3 × 18–22kg washers
1–2 × 27kg washers

The data operators share in workshops shows that mid-sized machines offer the highest revenue-per-square-metre in stores that sit between small suburban laundromats and full commercial facilities.

Think of it like running a café: your espresso machine is your bread-and-butter, but your long black and oat latte crowd still likes options.

How do dryers factor into machine size decisions?

Dryers are where margins quietly blossom. A mismatched washer–dryer ratio leads to congestion, complaints, and lost repeat business.

General rule operators lean on:

Pair 10–14kg washers with 14–16kg dryers
Pair 18–27kg washers with 23–30kg stack dryers

Dryer bottlenecks are one of the biggest killers of customer satisfaction — and satisfaction breeds consistency, another of Cialdini’s levers. If customers know the drying is quick and predictable, they come back without shopping around.

Are bigger machines actually more profitable per cycle?

Yes — but only if they’re used.

A 27kg washer might bring in triple the price of a 10–14kg unit, but if it sits idle 40% of the week, the numbers fall apart fast.

Here’s the simple equation most operators track:

High volume = high profit
High capacity = high margin (when demand exists)

Small stores rely more on volume.
Medium stores rely on a balance of volume and margin.

The trap new owners fall into is believing that big machines impress customers. In reality, people value speed, price, and ease more than capacity.

How do utility costs change across machine sizes?

Machine manufacturers publish detailed energy and water data, and the trend is clear across almost all brands:

Utility costs increase with drum size.
But revenue increases faster than utilities — if demand exists.
Efficiency drops sharply when big machines are under-loaded.

This is why leasing can be a smart strategy for operators who want flexibility as customer patterns shift. Utility bills behave differently in summer, tourist seasons, or times when local housing develops shift the demographic. Owning a fleet of oversized washers often locks you into the wrong economics.

FAQ

Is a 27kg washer too big for a small laundromat?

Usually yes, unless you have strong doona demand or nearby hotels. One is fine. Two is often overkill.

What size washer do most people prefer?

The 10–14kg range. It feels familiar and suits everyday laundry habits.

Should dryers be bigger than washers?

Yes — slightly. Bigger dryers reduce wait times and improve customer turnover.

Final Reflection

Most small and medium laundromats don’t win by going big — they win by going appropriate. The machine sizes that feel natural to customers tend to be the ones that ring the till the most, day after day. And for operators experimenting with their mix or planning a refresh, it often helps to explore flexible options like laundromat machines for lease, especially when adapting layouts to match local demand.
