How student is to urinal ratio is calculated?

Means, for 100 students, how many urinals are required and what basis those are getting calculated?

This depends on the building-code of the country in question. But typically figures are similar and some general guidelines from UNICEF are available, but unless you are legally required to adhere to the building-code it is worth asking some additional questions like:

- Are students allowed to leave class or does it all concentrate on the short breaks?

- Do students go home for lunch break (or is it only half-day classes anyways)?

- How many regular toilets are there as substitutes (and are those gender separated and/or partially exclusive for teachers)?

- How many simultaneous students are to be expected (think about alternating morning / afternoon classes for age groups)?

- How many times a day does it get cleaned / maintained?

Thus all in all it is hard to give a clear answer to this other then what might or might not be required by the national building-code.

Thanks for these pointers, Kris. Very useful.

Umesh: in case you have overlooked it: this thread has two pages. You'll find some answers to your questions on Page 1 of this thread.

Hi all,

in case you have not see the WHO guideline: Water, Sanitation and Hygiene Standards for Schools in Low-cost Settings:
apps.who.int/iris/bitstream/handle/10665...quence=1&isAllowed=y

And for UDDT here is a code of practice for UDDT:

Here you find also some information on numbers of students per toilet which might be useful:
