toilet / loo
A colloquial word for the toilet or restroom.
Entschuldigung, ich muss mal schnell aufs Klo.
Excuse me, I need to quickly go to the toilet.
'Klo' (toilet/loo) is the most common word for a toilet in everyday speech. It is used among friends and family, but in very formal or business situations, 'Toilette' (toilet) or 'WC' (restroom/WC) are often more appropriate.
Wo ist hier denn das Klo, bitte?
Where's the toilet here, please?
A very common and important phrase is 'aufs Klo gehen' (to go to the toilet) or 'aufs Klo müssen' (to need to go to the toilet). Note the preposition 'auf' with the accusative to express movement toward it.
Die Kinder müssen vor der langen Autofahrt noch mal aufs Klo.
The children need to go to the toilet once more before the long car ride.
'Klo' is a shortened form of the word 'Klosett' (closet/toilet). The word 'Klosett' itself was borrowed from English ('closet'), but today it is hardly used in German anymore.
Früher stand auf den Türen oft „Klosett“.
In the past, the doors often said 'Klosett'.
toilet / restroom
Toilette and Klo can refer to the same room or restroom. The key difference is register: “Toilette” is neutral and also polite, while “Klo” sounds distinctly more colloquial. In formal situations, “Toilette” is therefore more appropriate; among friends, “Klo” is common.

Warte bitte kurz auf mich, ich muss noch aufs Klo.
Please wait for me a moment; I need to use the restroom.
Entschuldigen Sie, können Sie mir sagen, wo die Toilette ist?
Excuse me, could you tell me where the restroom is?
