People now reselling Sydney Sweeney’s controversial product made from her bathwater after it sells out in seconds

Sydney Sweeney's new commercial venture to sell a product made from her bathwater has been an overwhelming success for the Euphoria actor.

The 27-year-old has controversially profited from soaking up the suds in a warm bubble bath, and rather unhygienically, she has managed to produce a cleaning agent out of it.

It is all thanks to her having became the poster girl for Dr. Squatch, a personal care production company, which The White Lotus star became an ambassador of after posing in a steamy tub for a provocative ad.

In the commercial, which aired on live TV, Sweeney says: "Hello you dirty little boys, are you interested in my body... wash?"

This short appearance paved the way for Sweeney to team up with Dr. Squatch to sell a limited 5,000 bars of 'Bathwater Bliss' soap made out of her own bath water - which sold out in the matter of seconds when it went to market on Friday (June 6).

"When your fans start asking for your bathwater, you can either ignore it, or turn it into a bar of Dr. Squatch soap," Sweeney said in a press release.

"It’s weird - in the best way, and I love that we created something that’s not just unforgettable, it actually smells incredible and delivers like every other Dr. Squatch product I love."

The soap went on sale for $8 at 12pm EST, and due to how in-demand the product was, the website subsequently crashed.

Taking to Instagram, Dr. Squatch posted: "Y’all crashed the site. The Sydney’s Bathwater Bliss launch has been insane! We seriously appreciate the Squatch-sized enthusiasm.

"We’re working hard behind the scenes to make sure the right folks – on a first come, first served basis – get their hands on the bricc. Thanks for your patience."

Bathwater Bliss has since been re-listed on eBay for as much as $2,000, with some bars fetching for $100.

While speaking with GQ, Sweeney, of Spokane, Washington, explained how the process went down.

"When we were at the [Dr. Squatch] shoot, they had a tub for me. And I actually got in there and I took some soap, and we had a nice little bath and they took the water. So it’s my real bath water," she confirmed.

"I wanted to have it lean towards my home roots, so there’s this really outdoorsy scent of, like, pine and earthy moss and fir. So it smells super manly. But then there’s some city bath water mixed in."

While in a press release for Dr. Squatch, Sweeney - who owns a sprawling $13.5 million estate in Florida, as well as a more modest $3 million home Bel Air, California - said how she could either ignore her fans 'asking for your bathwater' or 'turn it into a bar of Dr. Squatch soap'.

"It’s weird - in the best way, and I love that we created something that’s not just unforgettable, it actually smells incredible and delivers like every other Dr. Squatch product I love," she added.
