No. If you’re tiling a floor, you probably want the cutter beside you on the floor anyway – it will be a nuisance to keep getting up and down. For walls, the opposite is true, and it’s tempting to use any old table to place it on. That’s fine, as long as it’s sturdy. It needs to support your weight as you score the tile. If it wobbles, it will affect your accuracy and lead to more waste. A folding workbench is a convenient and very versatile solution.
