Instructions state that I should not fit a WC pan on top of the waterproof laminate I am about to lay in a 2.5 x 1.7m bathroom. I do not foresee expansion problems. Is there any other reason not to do so? Also, is it acceptable to lay the laminate direct onto a level hardboard layer, which is on a suspended wood floor, or should I add another underlay?
TIA
