Outdoor WC substructure cladding

Hello community,

I am currently building an outdoor toilet in our garage (a walled-off area in the garage that is accessible from outside). I am wondering which drywall panel I can use to clad the [UK]?

It won’t get wet in the toilet, but possibly a slightly higher humidity.

Can someone give me advice? Is it better to use cement-based panels?

Thank you in advance

Unfortunately, I cannot give you an answer to your question. Just a note from my side that this results in a change of use (requiring approval) and if the garage has a boundary construction, there may be problems.

Thank you for your note. The WC has been approved in the course of the new construction.

Use green moisture-resistant boards, then you are on the safe side...
