Many people are now opting to purchase a front-loading washing machine. The benefit of a front-loader is that a bench top can be installed over the top of the machine to provide additional bench space. Your laundry basin can be cut into the bench top to achieve a seamless finish.
If your laundry space is limited, consider having a built-in laundry installed, wherein the appliances and laundry tub are installed behind cupboard doors. This option is great for maximising the use of small laundry spaces.
