"Вибачте, де туалет?"

Or 'Pardon, where is the toilet?' BTW For speakers of British English a 'bathroom' is a room with a bath in it, and a 'toilet' is a room with a toilet in it...

Why are bathroom and washroom not accepted?

The english here is incorrect, we do not call bathrooms "toilet", the actual fixture is the toilet.

Typically, you would say, "Excuse me, where is the restroom (bathroom)?" We don't use "toilet" in this scenario.

I don't understand why this is translated as Where is "this" toilet? Wouldn't it need to be "де цей туалет"?

I don't understand why "де туалет" translated where is "this" toilet. Wouldn't it be "де цей туалет?"

Should say 'THE toilet' (bathroom) not 'THIS bathroom'!

We used the word 'лизничка' for the 'washroom/bathroom'. I've always thought it was disrespectful to ask 'where the toilet is'. I've always been uncomfortable using the word 'туалет'....in the 'old'days they used to call it an 'оборна' (outhouse), because indoor toilets didn't exist then.

and what is wrong with "I'm sorry..." :)|

In Canada it is called "washroom"

Could "туалет" also mean bathroom? Not sure there's a difference, but that's why I asked, lol.

I often use this when I was in Ukraine. Very useful phrase.

Before I answer you, what are you going to do in the toilet?

I have to know what your purpose for going to the toilet is.
