Minimum Heights in New build WC

[holboob]

Hi there

We are currently building a new-build 2 bed house that requires a ground floor WC under the new Pat M regs. This is to be located under the stairs and so I was wondering whether there is a minimum head height requirement at the back of the WC, or overall in the room as the ceiling will be sloped?

Any help of further infromation would be much appreciated as I cannot find anything in the regs stating any requirements.

Thanks

i'm not completely sure, but a ceiling only needs to be at a height that is practical.

There is no minimum height
