Frequently asked questions
Drying Rooms
What is a drying room and why is it important on construction sites?
A drying room (also known as a dry room or change room) is a heated space where workers can dry wet PPE and change clothing in comfort. It helps improve site hygiene, reduce downtime, and support worker welfare, making drying room unit hire essential for most construction and infrastructure projects.
Do you offer drying room hire for building sites?
Yes, we provide flexible site drying room hire options across the south of the UK. Our drying room cabins are fully insulated, secure, and ready to use – ideal for short-term or long-term site setups. Whether you need a standalone drying room or want to combine it with a canteen or office, we can help.
What is included with your drying room cabin hire?
Our standard drying room cabin hire includes fitted benches, coat hooks, heaters, ventilation and anti-vandal features. Each dry room is a plug-and-play solution designed for fast setup and daily use.
Do drying room cabins include plug sockets?
No. As standard, we seal off plug sockets in our drying room units for safety reasons. Although the ventilation helps control humidity levels, it is not recommended to plug in any electrics due to the humid environment.
How much does drying room hire cost?
Drying room hire costs vary depending on unit size, hire duration, and any optional extras. For an accurate quote, get in touch with our team – our prices are competitive, with no hidden charges.
What size drying room containers do you offer?
At Storage on Site, we offer a range of drying room sizes for your construction site. From 8ft drying rooms to 32ft drying rooms, our units suit a variety of site scopes and can also be combined with other functionalities to make the most out of your cabin hire.
Some of the unit combinations we offer include canteen/drying room, office/drying room, or meeting room/drying room. Our container cabins are also suitable for stacking, and our 16ft drying rooms and 20ft drying room units are particularly popular for this purpose.
What’s the difference between a drying room and a portable changing room?
A drying room is heated and ventilated to dry clothing, while a portable changing room or changing room cubicle is focused more on privacy and space for workers to change. Our modular drying rooms can combine both features in one secure, stackable cabin.
Can I hire portable dressing rooms with drying space?
Absolutely. We supply portable changing rooms with built-in heating and hanging space for wet gear. Whether you need a small changing room or a larger modular changing room, we’ll tailor the layout to your team’s needs.
What changing room size do I need for my site?
The right changing room size depends on your team size and site layout. We offer a wide range of sizes, from 8ft to 32ft to comfortably serve any workforce.
You can find out more detailed information about our changing room dimensions on our individual drying room pages. Alternatively, give us a call on 023 8033 2266 and one of our friendly team would be happy to provide this information.
Are modular changing rooms suitable for stacking?
Yes. Our modular changing rooms and drying room cabins are container-based and designed to be stackable, saving valuable space on compact sites.
Can you deliver portable changing rooms to remote locations?
Yes. We deliver all portable changing rooms, drying rooms, and fitting rooms across the south of the UK using our own fleet of trucks. Our team handles tricky access points and ensures smooth delivery to both urban and rural sites.
Is it a legal requirement to have a drying room on site?
While there isn’t always a specific legal requirement to provide a drying room, UK Health & Safety Executive (HSE) welfare regulations do require suitable changing facilities for workers who need to change into specialist clothing. This includes access to a portable changing room, changing cubicle, or modular changing room that is secure, ventilated, and heated if necessary.
In practice, a drying room cabin helps sites meet these expectations – particularly in wet or cold working environments. Site drying room hire is a simple way to remain compliant and improve worker comfort.
What colours are your drying rooms available in?
Our drying room cabins are available in our standard RAL colours – 6007 (dark green) and 5013 (dark blue). Customisation options are available in any RAL colour and finish – just mention this to our team when placing your order.
Our drying room hire includes hooks, benches and heaters, providing a private and secure changing room for your workforce.
