She can hang in the penthouse and the poop-house. 

A 25-year-old traveling nurse invites TikTokers to “take a s–t” with her in the bathrooms of high-end locales — and rates them based on ambiance, toilet comfortability and TP quality. 

And she actually goes No. 2 in the process. 

“It helps when you’ve had a full meal at the restaurant,” Abbey Whalen told The Post. 

At Nobu in Palo Alto, Calif., Whalen was pleased to find that the Toto-brand throne had heat controls — “the warmest welcome I’ve had in a long time,” she told her TikTok audience from inside the bathroom.

But the rest of her review was crappy.

Whalen gave the elite eatery’s powder room a 4.1 out of 10, griping that the “nasty ass urinal” distracted from the “stunning” vanity; the bathroom lacked a hook for her purse, “which feels kind of sexist”; and the paper towels were “as thin as your ex’s ass.”

Although the aspiring TikTok star’s reviews may seem harsh, they began as a way for her to take a load off.

Earlier this month, Whalen felt out of place while dining with her boyfriend’s family at the famed French Laundry, the three-Michelin-star eatery in Yountville, CA.

“I never grew up with money… It can be a little bit uncomfortable sitting in places like that if you’re not used to that environment,” Whalen said. 

Her boyfriend, Aaron Mandler, came up with the concept for the “Come take a s–t with me’’ series at the dinner table. 

“My boyfriend said to me, ‘I have an idea that’s going to do really well on TikTok, but it has to be you that does it, not me,’” Whalen said. 

The couple wanted “to show that polarity between taking a s–t, but also being a woman that likes to dress up and go out,” said Whalen, who makes it a point to show off her outfit in every video. 

At the end of her TikTok at The French Laundry, her first bathroom review, Whalen felt “five pounds lighter.” 

“I thought it was a funny way to make the space inviting for everybody,” Whalen said. 

Whalen, whose three TikToks so far have amassed over 2.5 million views, plans to continue inviting people to the restroom with her — but only in porcelain palaces.

“I definitely want to stay in the luxury space,” she said. “Luxury stores are the next place I want to expand to.”
