After hinting at a walk-out for weeks, The Block’s controversial ‘villain couple’ finally made it happen.

While promos for an upcoming episode suggest their return, on Sunday night it seemed like Sara and Hayden were done with the renovation show for good.

They were devastated after receiving harsh feedback for their master ensuite bathroom, and received the lowest score out of the five couples for the third week in a row.

“We’re just being made to look like absolute fools,” an emotional Sara told cameras after filming.

“That bathroom did not deserve to be last … you know what? I’m f**king walking. I don’t want to do this.”

Trying to revive themselves after the past two room challenges, Hayden and Sara tried to lock in a positive reaction from the judges with a $75,000 luxurious and expensive ensuite bathroom fit-out that made The Block history.

"We have put everything into the bathroom, all our cards are on the table, we're showing everyone what we're actually made of," said Sara.

In their arsenal was a feature marble wall, herringbone tiling and an $11,000 brass bathtub. And while the judges loved the tub, this alone is where their positive feedback stopped.

Instead, Shaynna Blaze, Neale Whitaker and guest judge and real estate specialist, John McGrath, criticised the master ensuite for its poor layout and overall design.

"I don't think it belongs in this bathroom," said Neil

"The rest of the bathroom doesn't feel like it goes."

Relaying the feedback, host Scott Cam had these final words.

"In summary your bathroom this week is a mix of triumph and disaster and your judges are very concerned about the lack of direction in your apartment design," he said, with Shaynna even offering a private mentoring session with the couple - something they apprehensively accepted.

Although they kept their composure during the group judging, the pair were clearly disappointed at receiving the lowest score out the five couples, with Sara storming off the set.

Speaking to a producer, she launched into a expletive-heavy rant.

“We put our heart and soul into that. F**k ’em. I don’t want to do this any more. I’m over it. Ah, f**k this," Sara said.

“This was the biggest mistake of my entire life. We don’t want to be here any more. I’m done. It’s embarrassing. You don’t f**king get it. It’s f**king embarrassing.”

And although they will continue to compete, the chances of them being the first contestants to ever walk out of The Block mid-season are clearly high.

Reacting to the drama, there was a mixed response from fans on social media. Some criticised Sara for her tantrum, while others didn't think the couple deserved the harsh feedback.

This is what they had to say.

The thing with Sara is... losing 3 weeks in a row isn’t embarrassing. Her behavior is. She’s taking the judge’s comments personally, and not constructively. She continues to think she knows best, and blows $75K on an ensuing bathroom. #9TheBlock

Geez people come on give Sara on #9TheBlock just a small break! Have some #empathy and see that she is legit not coping, and looks very close to the edge of a #breakdown.
We are better than this peeps!

#9TheBlock Has Sara never heard of Chantelle and Steve? They only won one room and walked away winners! I hope she does walk & they get someone grateful for the opportunity @TheBlock

I don’t like Sara and her carry on but their bathroom was better than Norm & Jess’s, whom I like, I think the other contestants may also say that their bathroom was not as bad as the judges say it was. But that’s The Block you’ve got to roll with the punches! #9TheBlock

#9TheBlock I actually like the bath in Sara & Hayden's ensuite too, but I'm not a huge fan of the tiles on the wall behind it. Not a fan of Sara's tantrum throwing either, but hey. ????☕

Why do the judges hate Hayden and Sara so much? I think they are killing it but they legit keep getting killed! #9TheBlock
