"Tini goes to toilet."
Translation:Tini pergi ke toilet.
The English sentence should be "Tini goes / is going to the bathroom / restroom / washroom." Native English speakers mostly avoid explicit use of the word "toilet" in everyday conversation, except to refer specifically to the receptacle that receives human urine and feces.
We find many, many ways to avoid using the (nearly taboo) word "toilet" except as above, and for toilet-training very young children.
