bathroom floor question

[brett71]

morning all

i am thinking about laying a karndean vinyl in the bathroom but apparently this needs to be laid onto plyboard, now this isn't an issue as to me the current chipboard feels like its given and not level, so my question is should i just replace the chipboard with a thick plyborad or will overboarding the chipboard do a job? sorry if this sounds like an obvious thing but its all new to me

If the current board is ridged & in good condition & you can live with any increase in height, cant see why it needs to be lifted.
