How to prepare for a conversation like this

Memorizing the lines is not enough: the other person will say their own thing, not what is written. What helps more is catching the key words by ear and keeping three rescue phrases ready: “I don't understand”, “repeat, please”, “slower”.

And one more thing phrasebooks do not mention: awkwardness gets in the way more than not knowing the words.

Frequently asked

How do you start a conversation in Spanish in this situation?

“A ojo, para el baño hacen falta unas cien piezas.” — Roughly speaking, the bathroom needs about a hundred tiles.. The first line in such a conversation is almost always the same, and that is the one worth learning: the other person will carry it from there.

What if you did not understand the reply?

Say “I don't understand” and “repeat, please” — both are in the rescue set. Admitting your language is still shaky almost always makes the other person more patient.

Should you memorize the dialogue?

No. It is more useful to catch the key words by ear: the other person will say their own thing, and a memorized line will not always fit their reply.
