Is there a standard height for toilets?

According to DIN 1387 and 1388, free standing toilets must have a height of 390 mm +/- 10 mm. There is no standard height for wall-mounted toilets. However, the above-mentioned standards are used as a basis. The recommended height, and standard height specified in the catalogue, is thus 400 mm, measured from the floor to the top edge of the toilet.
