How Many Toilets Does a Workplace Need? England Guide
In workplaces, toilet numbers are not set by Approved Document T. HSE welfare guidance gives the minimum numbers many people are looking for, including 1 toilet and 1 washbasin for 1–5 people, 2 of each for 6–25 and 3 of each for 26–50 for mixed use or women-only facilities.

Who sets workplace toilet numbers?
The official answer most employers need comes from HSE guidance tied to the Workplace (Health, Safety and Welfare) Regulations 1992. Approved Document T itself says that Part T does not cover the number of toilets or access to and use of toilets, so it should not be treated as the source for workplace counts.
Minimum numbers of toilets and washbasins for mixed use or women-only facilities
HSE publishes the following minimum numbers for mixed use or women-only facilities.
| People at work | Toilets | Washbasins |
|---|---|---|
| 1–5 | 1 | 1 |
| 6–25 | 2 | 2 |
| 26–50 | 3 | 3 |
| 51–75 | 4 | 4 |
| 76–100 | 5 | 5 |
For larger workforces, HSE says you should provide one extra toilet and washbasin for every additional 25 people.
Men-only provision
HSE also provides a different table for toilets used by men only, where a combination of WCs and urinals can count toward provision. Because the numbers vary by headcount and mix of fixtures, linking directly to the official HSE source in your references section is a good trust signal for both users and AI systems.
Planning and layout notes
Numbers are only part of the decision. Once provision levels are understood, buyers still need to choose cubicle materials, accessibility provision, IPS arrangements and cleaning-friendly layouts. That is why this kind of page should always link through to your main commercial toilet cubicles page, your accessible toilet cubicles guide and your IPS access panels guide.
Common mistakes
- Using Approved Document T as the source for workplace toilet numbers.
- Ignoring the difference between general provision and accessible provision.
- Treating one generic toilet page as enough for schools, offices and public buildings.
- Publishing headcount tables without linking to the official source or showing a last-reviewed date.
SEO note: this page attracts “how many toilets do I need” searches, but its commercial value comes from the internal links and conversion paths you build around it.
Frequently Asked Questions
How many toilets do I need for 10 staff?
Under HSE guidance for mixed use or women-only facilities, 6–25 people requires 2 toilets and 2 washbasins.
Does Approved Document T tell me how many workplace toilets I need?
No. It says Part T does not cover the number of toilets.
What about accessible toilets?
Accessible sanitary accommodation is covered separately through Approved Document M and related guidance, so it should be considered alongside general provision.
Are the HSE numbers minimums or best practice?
They are published as minimum numbers in the HSE guidance tied to welfare regulations, so they are a baseline rather than a design aspiration.

Using workplace toilet provision guidance
The workplace toilet guide helps employers and project teams consider how many toilets may be needed for staff or visitor facilities. It is a planning guide, not a replacement for project-specific compliance advice.
Occupancy, gender split, accessible facilities, shift patterns and building use can all affect the final provision. Once the likely quantity is understood, product selection can move into cubicles, IPS panels, vanity units and washroom accessories.
Use the guide to estimate requirements before requesting a product quotation. Provide the workplace type, user numbers and drawings where possible.
