It is recommended that you have a draining board for sinks in your kitchen since it has many benefits:
First, having a drainboard saves your countertop space. You can put your washing vegetables or dishes on the drainboard. And if the space is not enough, you can even lay a chopping board over the drainboard, enlarging your working space to a large extent.
Second, having a drainboard helps keep the countertop dry. After washing the dishes, they may still be wet. If they are placed directly on the countertop, you’ll end up getting a wet surface and have to wipe the countertop manually, which is clearly a nuisance.
So as we can see, having a drainboard in your kitchen is certainly beneficial and convenient, which is why you should consider making the upgrade.
