I dont have access to the current inventory of slab thicknesses of Carrara White Marble in Italy. However, architectural and construction companies often offer Carrara White Marble slabs in the following thickness options:

- 2 cm (0.79 inches)
- 3 cm (1.18 inches)
- 4 cm (1.57 inches)

The thickness variation depends on the intended use of the marble, as well as the requirements of the project.
