New vanity position:
If installing a new or relocating an existing vanity basin grab 2 one foot long (300 mm) elbow stainless steel flexi hoses from the plumbers merchant shop and place them on the end of the tread hanging down from the basin taps underneath inside the cupboard or so on as the case maybe below if a pedestal set.
Measure from the floor to where the elbows are hanging and add 4-inches (100 mm) to this measurement. This is the height you will place your new timber noggin at to screw the new wingback elbows to.
Be careful to take note of the best position for these wingbacks in relation to the open cavity provided for this plumbing.
