Designing an aged care laundry is about much more than buying a few commercial washers and dryers. It is a clinical environment that must control infection risk, meet Australian standards and keep operating costs predictable over the long term.
Why laundry design matters
Aged care residents are highly vulnerable to infections, and linen can carry pathogens such as influenza and gastroenteritis if it is not handled, washed and stored correctly. A well‑designed laundry supports safe workflows, protects staff, and helps providers demonstrate compliance during audits and accreditation.
Key standards and regulations
The core reference for healthcare and aged care laundries is AS/NZS 4146:2000 Laundry Practice, which outlines requirements for handling, processing and disinfecting linen. In addition, the strengthened Aged Care Quality Standards include infection prevention and control obligations that extend to how linen is managed from collection through to storage.
Providers must ensure that both on‑premise laundries and any external laundry contractors can meet AS/NZS 4146 requirements, including documented validation of disinfection cycles. Policies, procedures and staff training need to align with these standards, not just in theory but in day‑to‑day practice.
Choosing the right machine types
Aged care laundries will need a mix of sluice washer‑extractors and industrial dryers sized to meet the capacity required for the number of beds and linen changes per day.
When selecting washers, look for models with built‑in heating and programmable disinfection cycles that can reliably maintain required temperatures and hold times. Dryers should offer precise temperature control and large lint filtration to reduce fire risk and support rapid turnaround of bedding and towels.
Thermal disinfection and cycle design
AS/NZS 4146 sets expectations for thermal disinfection, such as maintaining wash temperatures of at least around the mid‑60s degrees Celsius for a sustained period, or higher temperatures for a shorter hold time. Machines must be capable of achieving and documenting these conditions, often via dedicated healthcare or “thermal disinfection” programs.
Cycle design should match soil levels and risk: heavily soiled incontinence linen may require pre‑wash stages, higher temperatures, and appropriate detergents, while personal clothing may use gentler cycles that still meet disinfection requirements. Facilities should regularly verify that wash processes deliver the required microbial reduction, using temperature logs or external validation where necessary.
Infection control and workflows
Good laundry design separates clean and soiled workflows to minimise cross‑contamination risk. This typically includes distinct zones or rooms for receiving soiled linen, processing, finishing and storing clean items, with hand hygiene stations and personal protective equipment readily available.
Staff procedures are just as important as equipment. Linen should be bagged at the point of use, transported in designated trolleys, and never sorted or rinsed in resident care areas. Clean linen must be stored in a clean, dry space away from moisture, dust and aerosols, and always separated from used items.
Water and energy efficiency
Modern industrial washers can significantly reduce water consumption per kilogram of linen through optimised drum design, smart controls and accurate load sensing. Selecting machines with high G‑force extraction reduces residual moisture, which in turn cuts dryer run times and energy use.
Heat‑recovery systems, gas‑heated dryers and well‑insulated hot‑water systems can further lower operating costs and emissions over the life of the laundry. When specifying equipment, consider total cost of ownership, including water, electricity, gas, chemicals, servicing and expected machine lifespan, rather than purchase price alone.
Example layouts for aged care laundries
A typical on‑premise aged care laundry might be planned around a “dirty‑to‑clean” flow, with separate entry points for soiled and clean items. Soiled linen enters a receiving and sorting area, moves into the wash and drying zone, then passes to a clean finishing and storage area before distribution back to resident areas.
Larger facilities or those with higher acuity residents may choose barrier washers installed between the dirty and clean rooms so linen never travels back through soiled spaces once processed. For smaller homes, partnering with a compliant external laundry for flats (sheets, towels) and keeping personal laundry on‑site can be a practical compromise, provided both operations follow AS/NZS 4146 and aged care quality requirements.
Building a compliant, future‑ready laundry
To design or upgrade an aged care laundry, start with a clear understanding of resident numbers, case mix and linen types, then map these against AS/NZS 4146, infection control obligations and audit expectations. From there, work with a specialist laundry partner to size equipment correctly, configure compliant disinfection cycles, and plan a layout that keeps soiled and clean workflows separate while optimising efficiency.
Ongoing staff training, documented procedures and regular validation of laundry processes will help ensure that the facility not only passes accreditation but consistently delivers safe, hygienic linen care for residents.
