This will depend on a number of factors: whether you want engineered or solid flooring, which species of wood you prefer, whether you want the floor to be floated or glued, and whether the strips are to be laid straight, diagonally or otherwise.
Other criteria will also come into play:
- The lighting of the room, and the colours of the walls and furniture. If the room is fairly light, use a dark floor – and vice versa.
- How much the room is used. A bedroom will get much less traffic than a hallway leading to the front door. Depending on how much the flooring will be used, you will want to choose between European or exotic timber species of varying degrees of hardness.
- If you live in an apartment, building-specific rules applying to owners.
- The characteristics of the subfloor.
