In most homes today, yes. The cross layered core is far more stable over concrete slabs and under floor heating, and the surface is the same timber.
Can engineered hardwood be refinished?+
It depends on the veneer thickness. A thicker wear layer takes one or two sandings; a thin one should be treated as a finished surface and replaced rather than refinished.
Can it go in a bathroom?+
No. It is still wood at the surface, and standing water and steam are what ruin wood floors. Use a porcelain plank or a vinyl plank there instead.
Does it work with underfloor heating?+
Most engineered boards do, within the temperature limits the manufacturer sets. Check the product page and keep the floor temperature steady rather than cycling it hard.
Engineered Hardwood Flooring
Real wood on top, a cross layered core underneath. The veneer gives the grain and the colour of solid timber; the core is what keeps the board from cupping when humidity swings.
That construction is why engineered hardwood can go over concrete and in rooms where solid wood is a risk. It is still wood, so it belongs in living areas and bedrooms rather than bathrooms or laundries.
The wear layer decides how many times a floor can be refinished. A thicker veneer can be sanded back once or twice; a thin one is a single lifetime floor. Acclimatise the boxes in the room before laying, whatever the thickness.
