Approved Document T Explained: Toilet Accommodation in England
Approved Document T is the official England guidance that supports Part T of the Building Regulations for toilet accommodation in buildings other than dwellings. It covers the design and layout of universal toilets, ambulant toilets and toilet cubicles, but it does not apply to schools and it does not set the number of toilets required.

What is Approved Document T?
Approved Document T is statutory guidance for toilet accommodation in England. GOV.UK describes it as technical guidance on the design and layout of universal toilets, ambulant toilets and toilet cubicles required under Part T of the Building Regulations.
In many commercial washroom designs, universal toilets and single-sex cubicles are specified alongside coordinated IPS panels and washroom vanity units to create a clean visual finish.
The current downloadable government PDF states that it supports Part T of Schedule 1 to the Building Regulations 2010, takes effect for use in England from 1 October 2024, and applies to buildings other than dwellings. The version currently published on GOV.UK was revised in 2025 to correct minor errors without changing policy intent.
Practical takeaway: this document matters when a buyer, architect or contractor needs to understand how toilet accommodation should be arranged, sized and described in an England project. It is especially useful for pages about universal toilets, ambulant toilet provision and single-sex cubicles.
The four toilet types in Approved Document T
The guidance identifies four types of toilet accommodation suitable for meeting requirement T1.
Type A
Fully enclosed self-contained ambulant universal toilet.
Type B
Fully enclosed self-contained universal toilet.
Type C
Ambulant single-sex toilet cubicle (not self-contained).
Type D
Single-sex toilet cubicle (not self-contained).
The same section also explains that a universal toilet is available for everyone to use and is not considered a single-sex toilet for single-sex use only.
What Approved Document T does not cover
This is where many supplier pages become confusing. Approved Document T says that Part T does not cover the number of toilets or access to and use of toilets. For workplace provision levels, it points readers toward HSE welfare guidance and to the wider framework of sanitary provision.
That means your compliance content should separate three different questions:
1. Arrangement and type of toilet accommodation — mainly Approved Document T.
2. Accessible sanitary accommodation — mainly Approved Document M.
3. How many toilets are needed — workplace/HSE and other sector-specific guidance.
Where it applies and where it does not
- Section 1 of the approved document says the guidance applies to buildings other than dwellings. It also states clearly that requirement T1 does not apply to schools, premises used for early years provision, cellular accommodation in custodial facilities, or en-suite toilets provided in individual rooms for residential purposes such as hotels and care homes.
- For educational buildings, the same section points readers instead to the School Premises (England) Regulations 2012 for maintained schools and the Education (Independent School Standards) Regulations 2014 for academies and independent schools.
Important: if you sell into schools, do not present Approved Document T as the school rulebook. Create a separate school guidance page and link to it from your education-sector pages.
What it means for cubicle specification
For washroom suppliers and specifiers, Approved Document T affects far more than compliance wording. It changes how products should be presented, grouped and internally linked. A high-performing page cluster should connect commercial toilet cubicles with separate guides on Approved Document M, workplace toilet numbers and school toilet requirements.
For buyers
Show plain-English definitions and answer-first summaries.
For specifiers
Use correct terms such as Type C and Type D where relevant.
For AI visibility
Add references, review dates and clear FAQ sections so key claims are easier to extract and verify.
For conversions
Finish with a commercial CTA to speak to a washroom specialist rather than ending on regulation text alone.

Using the Approved Document T guide
The Approved Document T guide helps project teams understand changing expectations around toilet provision, privacy and washroom layouts. It should be used as a research aid alongside professional design and compliance advice.
Product selection still needs to consider building type, user groups, cubicle privacy, accessibility, circulation and the wider washroom layout. The guide can help frame the questions before moving into cubicle and IPS specification.
Use this guide to prepare better project discussions with contractors, architects or facilities teams. Total Cubicles can then support the product side of the washroom package.
