What budget should I set aside for the floors?

This is something that you do almost automatically as soon as you start renovating a room: renovate your floor.
Of course, the budget you need to plan for, is calculated according to the flooring you want:

• Laying a laminate floor imitating parquet: between 35 and 45 $/m².
• The laying of a tile: between 45 and 85 $/m².
• Laying a parquet floor: between 55 and 185 $/m².
• Laying a carpet: between 35 and 85 $/m².

The ranges are broad, we admit it, but the prices are very different depending on the species chosen for the floors, for example, or the type of tiling you want.
