A contestant on The Block has furiously clashed with Foreman Dan during Tuesday’s episode.

Han, one half of the Perth duo with her partner Can, blew up at the builder, accusing him of playing up the drama for the cameras.

They came to blows over changes to Han and Can’s bathroom, that left a concrete slab sitting in a doorway – and Dan did not approve.

Han argued that she’d gotten the go-ahead from the on-site plumber, but Dan insisted that wasn’t good enough.

‘He’s just a plumber, he doesn’t design anything,’ Dan argued with the frustrated Blockhead.

‘You’re not cutting any structural slab, no way,’ he added.

Han admitted she was ‘angry and frustrated,’ adding, ‘From where I’m standing, I’ve done everything right.’

She then blew up at the unsuspecting foreman.

‘I’m sorry, but this is absolute horses**t. This is all for the camera, this is absolute bulls**t,’ she ranted.

‘It’s an absolute stitch-up Dan. I’m trying to do my best job and really go by the process,’ she continued, raging.

‘It’s like pick on the good guy, pick on the person that’s doing it by the book. And I’m sick of it.’

Her words were not enough to change Dan’s mind, who continued to insist the team go by the book.

Things were not any better for Han and Can during Monday’s episode.

Han’s phone went flat and she slept through her alarm – missing the mandatory pre-start meeting.

As punishment, Foreman Dan shut down their site for two hours.

Earlier in the season, the frustrated tradie came to blows with the West Australian couple when the pair decided to take matters into their own hands and waterproof their bathroom.

Dan made it clear the team needed to wait for a waterproofer to do the job professionally, but they defied his orders and got started on the task.

Upon discovering that the pair had ignored his demands, Dan exploded.

‘What are you doing? You can’t be waterproofing,’ he told Han.

‘I just asked you, like, five minutes ago: You’re not allowed to waterproof. If I give you an instruction, you can’t disobey it.’

Dan raged that he has ‘lost trust’ in the pair after they sneakily applied a second coat of waterproofing agent despite his advice.

A furious Dan immediately reported the infraction to the site manager, leaving Han in tears.
