School washroom design and finishes keep evolving. Today, we see some of the most innovative design considerations in the education sector, with washrooms offering a wide range of safety, hygiene, and anti-vandal functionality. However, while new product design enables these leaps in usability, school washrooms must meet certain criteria.
How many toilets should a school have in the UK?
First, it depends on how many toilets your school needs. The answer depends on several factors, including the age of pupils, but also whether you’re in Scotland or the rest of the UK.
Toilet requirements for schools in England and Wales
Below are the number of toilets and washbasins required in schools across England and Wales:
- Pupils under 5 years of age: 1 toilet for every 10 pupils.
- Pupils over 5 years of age: 1 toilet for every 20 pupils.
- In special schools: 1 toilet for every 10 pupils, regardless of age.
- Where most pupils are under 11: as many basins as toilets.
- Where the majority of pupils are over 11: Washrooms with 1 toilet must contain at least 1 washbasin; Washrooms with 2 toilets must contain at least 2 washbasins; Washrooms with 3 or more toilets must have at least two-thirds the number of washbasins as there are toilets.
Other regulations to consider:
- Toilet areas for male and female pupils over the age of 8 must be separate.
- Toilets used by girls must not have urinals.
- Staff toilets, other than those designated for disabled access, must be separate from pupils’ toilets.


Toilet requirements for schools in Scotland
In Scotland, the regulations for school toilets are a little different:
- 2 toilets for every 15 pupils (up to 60 pupils).
- 2 toilets for every additional 30 pupils (up to 300 pupils).
- 2 toilets for every additional 60 pupils over 300 pupils.
- 4 wash hand basins for the first 30 pupils.
- 4 wash hand basins for the next 30 pupils.
- 2 wash hand basins for every additional 30 pupils up to a total of 300 pupils.
- 2 wash hand basins for every additional 60 pupils over 300 pupils.
In addition to the above criteria, sanitary bins are also needed in cubicles for the disposal of sanitary products for girls. Every toilet should be adjacent to a washbasin, and each toilet should have a locking cubicle to provide sufficient privacy.
Many primary schools also include reduced-height school toilets designed for young children; although this is not a legal requirement, it helps promote good toilet hygiene for younger children.
Are unisex toilets legal in schools?
In recent years, there’s been a move toward unisex washrooms. These have been shown to reduce bullying and help promote better hygiene. Same sex washrooms might sound unusual, but with full-height cubicles - meaning panels run floor to ceiling - privacy is maintained, leaving the communal hand wash area free from social gathering and misbehaviour. Often, the communal hand wash area forms part of a wider open-plan space and can be seen and monitored by all members of faculty staff easily. Unisex toilets are legal in the UK and are proving a popular choice for schools across primary, secondary, sixth form, and college campuses.

Advances in school washroom design
Alongside a move toward unisex washrooms, school washroom technology has also advanced. Following the coronavirus pandemic, schools are keen to improve their hygiene standards. As a result, materials like Altro Whiterock have become standard, providing easy-to-clean wall surfaces with antibacterial properties and a high fire rating. Vinyl anti-slip safety flooring is also widely used, with sensor activation from light switches to toilet and urinal flushes, taps, and hand dryers. This combination significantly reduces touch points in the washroom, delivering a huge benefit in hygiene. You can read our feature on How To Improve School Toilets here.
TMV3 valves
You will need to ensure thermostatic mixing valves are used on all hot feeds in your school washroom. These devices blend both hot and cold water feeds to deliver a temperature-controlled warm feed to taps. This protects users from scalding. While some sensor taps have a TMV3 built in, most schools fit them on the main hot feed to wash basins and changing room showers.

Modern Advances in School Toilet Blocks to mitigate Antisocial Behaviour
School Toilet Blocks always used to be forbidding places – a haunt of bullies with the waft of cigarette smoke and more recently a place where Mobile Phone Cameras are feared.
That has changed dramatically in recent years, and School toilet blocks are now designed to prevent Antisocial Behaviour, save water and discourage using the area as a hangout.
