Blowing your nose or answering the call of nature could be the next thing to get expensive.
The world's number-two maker of tissues says big price rises are on the way.
Swedish firm Essity competes with the likes of Procter & Gamble and Kimberly-Clark.
It says it faces record-high prices for raw materials, energy and distribution.
On Wednesday (January 26) it reported profits down by over a third, even as sales rose by 11%.
And the company says there's no sign that costs will come down any time soon.
That all makes price hikes unavoidable.
Exactly how much a trip to the toilet will cost, depends where you are.
Essity says the timing and size of price rises will be decided locally.
And it all leaves consumers with a problem.
Switching to a cheaper brand of toilet paper might be possible, but reducing consumption altogether... that could be a challenge.
