2 Trough urinals: generally made from stainless steel and installed where the
risk of vandalism is high – for example, in public conveniences. The trough
is available in different lengths according to the number of people that are
expected to use it. The trough has a waste connection and the trough floor
has a built-in slight fall to allow the urinal to be installed level.
3 Slab urinals: manufactured from fireclay and assembled on-site. The channel
in the base of the urinal is laid to a slight fall and the waste connection is
made directly to the drain via the channel into a trapped gulley.
