For atypical washbasin orders the available space is to be measured.
When installing a plate washbasin in a niche dimensions of the niche at the rear and at the front on the front wash basin edge are to be stated.
Further angle brackets are to be measured on both sides. If the front dimension is smaller than the rear dimension, a large gap between the washbasin and the wall can be expected (the niche closes, the angle is less than 90 °).
Note. All the presented dimensions must be measured in the required counter top height.
Common height for washbasin counter top is 850 mm from the floor.
