The recommendations for this product are presented below.

The recommended interior space is 1,100 mm × 900 mm.

In no case may an increase in length compensate for an inconvenient or insufficient width. An area of 1100 × 800 mm, although it is 9% larger than an area of 900 × 900 mm, seems inadequate as a comfortable space for showering. If a space of 900 mm width cannot be provided, it is important to recognize that the system will inevitably be less spacious than a shower space of size 900 × 900 mm where the user can be positioned diagonally.
