There is no hot water in the shower.
'Doccia' — stress the first syllable: 'DOC-cia'. The CC + I makes a 'ch' sound, similar to 'church'.
Use to report a plumbing problem. State it as a fact rather than a complaint — this prompts faster action.
'Non c'è acqua calda' = 'there is no hot water'. 'C'è' (there is) negated becomes 'non c'è' (there is not). 'Acqua calda' = hot water; 'acqua fredda' = cold water. 'Nella doccia' = in the shower.
L'acqua non si scalda — è sempre fredda.
The water does not heat up — it is always cold.
Adds emphasis
Il rubinetto perde.
The tap is leaking.
Reports a dripping tap
Il water è intasato.
The toilet is blocked.
More serious plumbing problem — 'water' is the Italian word for toilet bowl
Italian hotel plumbing in older buildings can be temperamental. Sometimes the hot water boiler (scaldabagno) simply needs time to heat. Running the tap for 2–3 minutes before concluding there is no hot water is worth trying. If the problem persists, Italian hotel staff respond quickly to direct, calm reports.
