    Well-designed workplace toilets are not only a necessity for hygiene and comfort, but are also essential for the safety and accessibility of all employees, visitors and customers. To ensure everyone can use the facilities comfortably, different types of toilet cubicles are designed to cater to the needs of different individuals. Here, we’ll delve into the world of workplace toilet cubicles, covering the standard toilet cubicle sizing, as well as ambulant disabled, enlarged, and wheelchair accessible options.

    Standard Toilet Cubicles

    The go-to toilet cubicle for most workplaces is the classic standard cubicle. These cubicles aim to offer a practical and accessible space for employees to utilise. As standard, with a width of 800mm and depth of 1500mm. 

    The door is designed to open inward, with a width of roughly 665mm. Despite these being the standard dimensions, many organisations opt for larger sizes to enhance both the look and functionality of the space. To make sure everyone can comfortably use the cubicle, it is essential to have a manoeuvring area with a diameter of 450mm.

    Enlarged Toilet Cubicles

    Every workplace that provides multiple toilet cubicles has a responsibility to ensure that at least one of them is suitable for those who require more space. The enlarged cubicle offers comfort and convenience, featuring dimensions of at least 1200mm in width and 1500mm in depth, with a minimum width of 1200mm between surfaces. 

    The door opens outwardly, and for added safety, horizontal and vertical grab rails are installed around the toilet pan. These cubicles can also provide a solution for those with young children, offering baby changing facilities. An enlarged cubicle with baby changing facilities should be made available in both the men's and women's bathroom facilities.

    Ambulant Toilet Cubicles

    In any workplace, accessibility is crucial and this extends to the restroom as well. To cater to the needs of those with mobility limitations, it is important for every bathroom to have a designated toilet cubicle. If there's only one cubicle in the washroom, it must be equipped to serve individuals who are ambulant disabled. 

    To comply with the toilet cubicle specifications, the door should open outwards and there should be sturdy grab rails on the sides to offer stability. With a minimum width of 800mm and a minimum depth of 1500mm, the cubicle provides ample room for comfortable use, and with a minimum width of 800mm between surfaces, there's plenty of space to manoeuvre.

    Wheelchair Accessible Cubicles

    Workplaces must prioritise the needs of those with mobility challenges by offering wheelchair-accessible toilets. These restrooms are designed to provide ample space for manoeuvring and to make accessing the facilities as effortless as possible. The doors must open to a minimum of 900mm and the room itself must be at least 2200mm long. 

    To ensure compliance with building regulations, it is important to incorporate the necessary features, such as a toilet pack that meets Document-M requirements, and to make sure there are clear instructions for locating all the necessary elements within the room. Additionally, when concealing the disabled toilet cistern with IPS panel systems, it's crucial to prioritise the required dimensions of 2200mm x 1500mm to provide the most accessible experience for users.
