Where is the shower?
doh-VEH la DOH-chah.
When you want to rinse off sand and salt after swimming. Italian lidos have outdoor showers, typically near the shoreline and near the exit.
Dov'è means where is. La doccia is the shower. At Italian beaches, outdoor showers are called 'docce' (plural). They are cold water, typically activated by a button or foot pump. This phrase works everywhere.
La doccia è acqua calda o fredda?
Is the shower hot or cold water?
Beach showers are almost always cold.
Posso fare la doccia prima di andare?
Can I shower before leaving?
Asking permission to use the shower at the end of the day.
Dove posso sciacquarmi i piedi?
Where can I rinse my feet?
For a quick foot rinse rather than a full shower.
At Italian lidos, using the shower before leaving is considered good etiquette — taking sand into your car or hotel is preventable. Many lidos have a foot shower (lavapedi) near the exit specifically for rinsing sandy feet before putting on shoes. This is a standard feature of the Italian beach experience.
