Selecting the correct stainless steel wash trough size is critical when designing handwashing facilities for schools, workshops, and commercial buildings. Undersized troughs create congestion and hygiene issues, while poorly spaced tap layouts can reduce usability.
At Marko Stainless & Aluminium, we fabricate custom stainless wash troughs every day and understand how trough length and tap spacing directly affect performance in high-use environments. This guide explains the most common trough sizes used in Australia and how to choose the right configuration for your project.
Why Wash Trough Size and Tap Spacing Matter
Wash troughs are typically installed in areas where many users need access at the same time. Correct sizing and spacing ensures:
- Smooth flow during peak use
- Reduced queuing and crowding
- Improved hygiene outcomes
- Better long-term usability
In schools especially, troughs are often used by dozens of students at once, making length and tap spacing far more important than aesthetics alone.
Common Stainless Steel Wash Trough Sizes
1800mm Stainless Steel Wash Trough
The 1800mm wash trough is one of the most common sizes used in schools. It provides ample capacity while fitting comfortably within most wall layouts.
Typical applications include:
- Primary and secondary schools
- Outdoor handwashing areas
- Change rooms and sports facilities
In school settings, taps are commonly spaced at 400mm centres, allowing multiple students to wash hands simultaneously without crowding.
2400mm Stainless Steel Wash Trough
A 2400mm stainless steel wash trough is ideal for busier locations where higher throughput is required.
Common uses include:
- Large school campuses
- Shared student amenities
- High-traffic corridors
With 400mm tap spacing, a 2400mm trough comfortably supports multiple users at once and significantly reduces waiting times during recess and lunch breaks.
3000mm+ Stainless Steel Wash Troughs
In very busy environments, custom wash troughs over 3000mm long are often specified. These extended troughs are common in:
- Major education facilities
- Trade training centres
- Public amenities and recreation areas
Custom-length troughs allow designers to maximise wall space and accommodate large user groups efficiently.
Tap Spacing – Schools vs Commercial Applications
School Tap Spacing
In schools, 400mm tap centres are widely used. This spacing suits students of different ages and ensures efficient use during peak times.
This configuration is standard across many education projects and works well with 1800mm, 2400mm, and longer troughs.
Workshop and Commercial Tap Spacing
In workshops, factories, and commercial applications, tap spacing is often wider than 400mm. This allows for:
- Larger users
- Heavier handwashing tasks
- Reduced splash and interference between users
Custom tap spacing ensures the trough suits the specific use case rather than following a one-size-fits-all approach.
Custom Stainless Wash Trough Fabrication
One of the biggest advantages of stainless steel is its flexibility. Custom stainless wash troughs can be fabricated to suit:
- Exact wall lengths
- Required tap spacing
- Indoor or outdoor installations
- Integrated splashbacks and returns
At Marko Stainless & Aluminium, we regularly fabricate troughs to suit site-specific requirements rather than forcing projects to fit standard sizes.
Stainless Steel vs Alternative Materials
Plastic or composite troughs often lack the strength and longevity required in schools and workshops. Stainless steel wash troughs offer:
- Impact resistance
- Long service life
- Easy cleaning and hygiene
- Professional, vandal-resistant finish
For high-traffic environments, stainless steel remains the most reliable material choice.
