lino on floorboards

[PChurch]

Hi,

I am planning on putting some lino down on my toilet floor. The floorboards were quite warped but now I have sanded them down they are nice and flat.
I was thinking about putting down some hardboard and then laying the lino on that but should I use plywood instead? If, so how thick? Does it need screwing down? I think not because then the countersink holes will show through the lino. Maybe just glue it around the edges instead?

Any advice is very much appreciated

Thin ply is better, use copper pins to secure

Always use annular ring nails.
