Thank you for contacting Bio Bidet support!
The wash (posterior wash) is a more direct spray that focuses on the rear.
The bidet wash (feminine wash) is a wider spray that focuses more towards the front position - generally for women.
The sitz bath function is to mimic a gentle soaking feeling like a sitz bath.
