Wingbacks for a laundry tub and washing machine:
Firstly if at all possible position your laundry tub in the corner of the room. This always ensures enough space for any size of washing machine that may come along. Once you have it positioned place your tub wingbacks timber noggin about 4-inches (100 mm) above the height of the laundry tub top most lip itself and center of its width.
Then locate the center of the washing machine and place the timber in at 4-feet (1200 mm) above the floor height wise. These female wingbacks are to be placed flush with the outer finished wall ready to take two tiny washing machine tap valves.
If you prefer you can also place these washing machine wingbacks and taps lower out of sight behind the washing machine itself.
