Portable Toilet Block Solutions for Every Site

With current health and safety requirements, construction sites and events need accessible welfare facilities, including portable toilet blocks. Willbox has long been a trusted provider of anti-vandal shipping container toilet blocks across the UK, known for quality and durability. Each unit connects to mains waste or pairs with an effluent tank, offering an adaptable setup. Effluent tanks can be emptied as needed, either by Willbox or a vetted liquid waste collection partner. Built from steel, our portable toilet blocks are secure, durable, and easy to maneuver with a forklift or crane.

Our Portable Toilet Block Range

Single WC (Uniloo) 5’

A popular choice for small construction sites, the Single Uniloo provides a sturdy alternative to standard portable chemical toilets. This steel unit is insulated, featuring lighting, heaters, air vents, a toilet, and a sink. It can connect to mains waste or be used with an effluent tank, offering flexibility in compact form.

2+1 Toilet Block (12’ x 9’)

Our 2+1 shipping container toilet block is a versatile unit designed for double stacking and optimal site efficiency. Equipped with jacklegs, lighting, and heating, this insulated unit resists condensation and maintains a comfortable interior. The 2+1 layout includes a double gents section with two urinals, two sinks, and two toilets, plus a separate ladies section with one toilet and sink.

3+1 Toilet Block (20’ x 9’)

Our 3+1 anti-vandal toilet block, converted from a 20’ ISO shipping container, is highly durable and integrates seamlessly with other site units. It includes ISO corners and forklift pockets for easy transportation and can be stacked with effluent tanks or placed at ground level. This 3+1 shipping container toilet block features a gents section with three urinals, three toilets, and sinks, while the single section serves as a private or ladies toilet.

1+1 Toilet and Shower Block (10’ x 8’)

Our 1+1 toilet and shower block is a compact combination unit providing both toilet and shower facilities within a single 10’ x 8’ unit. Split into two separate sections, one side features a private toilet and sink, while the other provides a separate shower area. Ideal for construction sites and temporary accommodation, this practical unit provides essential welfare facilities while helping to maximise available site space.
