Was validating some Google translations and came upon this question:
How do say toilet paper in Chinese? The more technical term for the commonly used toilet paper is 抽取式衛生紙, what about the Western toilet paper rolls?
In Hong Kong "Toilet paper" is simply called 廁紙.
Before the modern toilet paper, people were using 草紙(rough straw paper) for toilet paper.
As for a roll of toilet paper , it is still called " 廁紙 " ( with classifier if needed. For example 一卷廁紙 ) and the more technical term would be 卷裝廁紙
For tissues in a box, we call it 紙巾 (with classifier if needed. For example 一盒紙巾)and the more technical term would be 盒裝紙巾
*衛生紙 is another name for 廁紙 or 紙巾.
(sorry for reposting this answer, first time using the comment section and didn't like how the comment was formatted)
For those wanting to learn Chinese
I'll add in some other examples for those in taiwan
