Another hopefully quick one.
Part of the reno i am doing has a 2-3 cm lower floor for some reason (the old toilet area). I could tile it at the height it is but i thought it would look better to raise this level to match the rest of the tiled area. It is only around 1 sq/m.
there is nothing in the room at the moment (no toilet).
Self levelling compound or something else? As cost effective as possible.
Plans attached for reference.
