AS above, I’d go with a kitchen or bathroom paint. Probably a bathroom as they are designed for humid atmospheres.
I’m biased* but I’ve done the bathrooms and high traffic areas of my house with Dulux Trade diamond. It has been good for nearly 4 years now. I’ve been suprised by how tough it has been when scrubbing marks off in the utility room. They do a standard retail product as well, I can’t remember the branding.
*I work for Akzonobel so get it cheap, opinions are my own. If you want professional advice then try the Dulux decorating centres as deco is not my area.
