Quantity of Applicances

In general, one urinal should be counted as equivalent to one WC when calculating the numbers of appliances required. The following refers only to the quantity of appliances within separate-sex facilities.

When calculating the number of appliances required in male facilities, every male toilet should have at least one WC, and at least one WC per 4 urinals or part thereof. [4]

To determine the number of WC’s and urinals required:

Total units required / 5 = WC’s required (round up to integer)

Total units - WC’s = Urinals required

It is recommended to provide one washbasin for every WC, however, where space is particularly constrained, it is acceptable to provide one washbasin for every two WC’s (Fig. 05). [5]

A minimum of one washbasin should be provided for every five urinals (Fig. 06).[5]

Where two or more washbasins are provided, at least one washbasin (and soap dispenser if separate) with its rim between 720 mm and 750 mm above finished floor level should be provided for use by children and people of short stature (Fig 05). [6] Additionally, a minimum of one urinal should be fitted at low level for children and people of short stature (Fig. 06). [7]

Where there are four or more WC cubicles in separate-sex toilet accommodation, one of these should be an enlarged cubicle (1200 mm minimum width) for use by people who need extra space (Fig 05). [8]

Requirements for cubicles, urinals and washbasins for wheelchair users and people with ambulant mobility impairments are described overleaf. Guidance on space planning for separate-sex cubicles, urinals and washbasins can be found in Section 3 of this document.

Separate-sex facilities should provide WC’s, urinals, and washbasins accessible to people with ambulant mobility impairments. Where applicable, male facilities should also provide urinals and washbasins accessible to wheelchair users.

Accessible WC compartments for people with ambulant mobility impairments, often referred to as ‘ambulant cubicles’, should make up 10% of cubicles, with a minimum of one (Fig. 07). [9] Example layouts for ambulant cubicles are provided in section ?? of this document.

Urinals accessible to wheelchair users and people with ambulant mobility impairments should have vertical grab rails fitted on either side of a urinal where stall privacy dividers are not fitted, in accordance with Fig. 47 of BS8300-2:2018. It is preferable to provide vertical grab rails in addition to stall privacy dividers as shown on page ?? of this document.

Separate-sex facilities should provide washbasins with various rim heights above finished floor level as follows:

Where it is impractical to provide washbasins at more than two heights, the lowest height required in that instance should be provided in addition to standard washbasins with rim 850mm above finished floor level (Fig. 08).
