Guest bathroom planning (3.9m²) - What arrangement?

Shower (for guests, dog, possibly a "dirt airlock" for children; so not used daily!)

Often, there are unrealistic expectations of what a small guest WC can handle. The pantry is bigger? It may not be daily use of the shower, but the toilet and sink are used several times a day?! You have to enter, turn around, elbows shouldn’t rub against the wall, head shouldn’t hit the washbasin edge, and when showering rarely, you also somehow want to undress, get dressed, maybe blow-dry your hair in the bathroom? The only good thing: the dog can’t run far away. There aren’t many options. Also, these are shell dimensions; plaster and tiles will still be added. My suggestion with a narrowed door by 12 cm [ATTACH alt="IMG_1499.jpeg"]90313[/ATTACH] Oh yes: The washbasin can do without a stud wall if water is installed in the partition wall.
