The Block is back – and so are the tears and tantrums.

On Monday night, Sonny and Alicia hit a snag with their bathroom renovation thanks to an undersized shower door.

The pair were warned by Foreman Dan that having an opening that is just 650mm wide was not likely to go over well with the judges.

It was all too much for Alicia to bear, and she broke down in tears of frustration.

‘I just don’t want to fail,’ she sobbed to her husband, Sonny.

Despite only being a few days into renovations, Alicia was feeling the pressure of having to make difficult decisions quickly.

The couple opted to ditch the screen around their shower to avoid the issue, but the process left Alicia rattled.

On Sunday, the show kicked off with high emotion, unexpected confessions and more tears than tiles.

This year’s season, filmed in Daylesford, Victoria, is already shaping up to be one of the most heartfelt yet, with several cast members breaking down as they opened up about their pasts, personal battles and the pressure of national television.

WA contestant Can, who is competing alongside her partner Hannah, was visibly emotional as she spoke about her journey with her sexuality – revealing this was the first time she’s come out publicly.

‘For a lot of my teenage years I felt a lot of shame and insecurity around my sexuality,’ Can said through tears in the show’s premier episode on Sunday night.

‘I have not professed that I have a girlfriend or that I am gay and I still hide it from certain people and in certain instances. So, to come on national TV is a big thing.’

Fellow contestant Mat, a South Australian hairdresser who is competing with his best mate Robby, also got choked up as he opened up about growing up gay in a strict environment.

There were tears on Sunday too when WA contestant Can, who is competing alongside her partner Hannah, broke down (both pictured)

‘High school was probably the toughest time of my life because I was a figure skating, gay boy at a private Catholic school with lesbians for parents,’ he revealed.

‘So it wasn’t f**king easy in the late ’90s.’

Tears continued when Han and Can missed out on their dream home after coming fourth in the ChillOut Festival float challenge, which determined house selections.

They were devastated to be stuck with a flat-roofed house they didn’t want.

Han was so emotional she had a long cry in the bath while Can tried to cheer herself up by Googling design inspiration.

‘I hate it. It’s like letting go of my child,’ Han moaned.
