How many kilograms of laundry does a 100 room hotel generate?

Often 300 to 475 kg a day with 75 percent occupancy, though it varies by hotel category and facilities. Include banquet, spa and pool linen in the estimate, because these can push the daily figure toward the upper end.

What capacity washer extractor is best for a hotel?

Many hotels use 25 to 50 kg machines. A mix of sizes often works well. Check the manufacturer's rated capacity, since cotton towels, sheets and blankets weigh and wash differently.

How long does a washer extractor cycle take?

Typically 45 to 60 minutes for standard hotel loads, depending on the programme. Cycle time depends on wash temperature, soil level, load size and extraction speed.

Do I need a backup machine?

A second or third machine gives you backup if one is down for repair. A spare machine also gives you flexibility during maintenance and peak weekends, which is when breakdowns hurt most.

Can small hotels outsource instead?

Yes, but compare outside rates with in house cost per kilogram before deciding. Include staff, chemicals, utilities and linen replacement in your own cost per kilogram so the comparison is fair.

How Many Washer Extractors Does a 100-Room Hotel Need?

Written by Kuldeep Kamboj Oct 09, 2026

Short answer: Most 100 room hotels need two to three washer extractors, often a mix of a larger machine for sheets and towels and a smaller one for uniforms and delicates. The exact number depends on occupancy, linen weight per room, operating hours and whether the hotel has a restaurant, spa or banquet hall.

What is a washer extractor and how does it work in commercial laundry?

A washer extractor is a machine that washes and spins linen in one drum. During the wash it tumbles linen slowly in water and chemicals. At the end it spins fast to push out water. This single machine replaces separate washing and hydro extraction steps, saving handling time and space in hotel laundries.

The quick sizing formula

Use this simple calculation:

Occupied rooms = total rooms multiplied by average occupancy
Daily linen weight = occupied rooms multiplied by kilograms of linen per room
Add extras such as restaurant linen, spa towels, pool towels and uniforms
Divide by operating hours to get required kilograms per hour
Divide by machine output to find the number of machines

A worked example

Take a 100 room hotel at 75 percent occupancy.

Occupied rooms: 75
Linen per room: around 3 to 5 kg, depending on category
Room linen: roughly 225 to 375 kg a day
Add F&B, spa and staff uniforms: perhaps 75 to 100 kg more
Total: around 300 to 475 kg a day

Now think about machine output. A 25 to 30 kg extractor washing machine typically completes roughly one cycle in 45 to 60 minutes, so it processes around 25 to 30 kg an hour in practice. Over an 8 hour shift, that is about 200 to 240 kg.

So for 300 to 475 kg a day:

Two 30 kg machines can handle the lower end
Two larger machines, say 30 and 50 kg, or three machines, handle the upper end and give breathing room

Please treat these as planning figures. Actual cycle times depend on your wash programmes and linen.

A commercial laundry washer of 25 to 30 kg is the workhorse for most hotels of this size, with a second, larger or smaller unit added for balance. If your hotel also runs a spa, pool and banquet hall, add a 30 percent buffer to the estimate and talk to your supplier about a third machine. It is easier to start with space and utilities ready for it than to retrofit later.

Why a mix of sizes works better

One huge machine looks efficient, but it has a weakness. On a quiet day, you run it half empty and waste water and energy. Several machines of different sizes let you:

Run full loads more often
Keep working if one machine goes down
Separate towels, sheets, uniforms and delicates
Handle peaks by running more machines in parallel

Don't forget the dryers and finishing

A washer extractor is only half the story. Make sure you plan:

Dryers with enough drum volume, often around double the washer capacity
A flatwork ironer for sheets and table linen
Folding tables and storage
Utilities: water, drainage, steam or gas, and power

Pick commercial washing machine for hotels models that offer programmable controls and strong extraction, since drier linen saves time and fuel in the dryer.

Signs you picked too small

Linen is delivered late
Staff run extra shifts
Machines run nonstop
Par stock keeps rising

Signs you picked too big

Loads are consistently half full
Water and energy bills look high for the volume
Machines wait idle for long periods

Plan the room layout

Leave at least a metre of clear space around each machine for loading, trolleys and service access. Keep soiled linen entering on one side and clean linen leaving on the other. Place dryers close to washers to cut handling, and keep the ironer near the clean linen store. A well planned room often adds more capacity than another machine would.

Revisit the numbers after the first year of operation. Actual occupancy and linen weight often differ from the plan, and a quick review helps you tune programmes and shift patterns.
