Learn Spanish (Latin America): Me afeito en el baño.

The verb here is afeitarse (to shave oneself), which is a reflexive verb. In Spanish, when you perform an action on yourself, you must use a reflexive pronoun. Me is the pronoun for "myself," so me afeito literally translates to "I shave myself."

Why isn't the word "yo" (I) included in this sentence?

In Spanish, the ending of the verb tells you who is doing the action. The -o ending in afeito already means "I shave." You could perfectly say Yo me afeito en el baño, but native speakers usually drop the yo because it is already clear from the verb.

If "me afeito" means "I shave myself," why does the English translation just say "I shave"?

In English, we usually drop words like "myself" for daily routines like shaving or dressing because it is assumed. However, in Spanish, you must include the reflexive pronoun (me) to make it clear that you are doing the action to yourself and not shaving someone else.

Does "baño" mean "bath" or "bathroom"?

Baño is used for both the physical bathroom (the room itself) and the bathtub or the act of taking a bath. In the context of this sentence, en el baño means "in the bathroom."
