In my (small) bathroom I have manky old lino over an uneven set of
floorboards which are not really floorboards - more like like
irregularly-shaped MDF offcuts - a real botch job it looks too. I thought I
would get rid of both of these and the lino in one go by replacing them both
with tongue-and-groove pukka wood flooring (not laminate).

Is this feasible in a bathroom, what with all the steam and dripping etc? If
so, is there any particular type of wood or varnish I should go for to suit
the warm and wet environment?

Thanks for any advice.
