The Block’s Sharon Johal and husband Ankur Dogra face another blow as they fail letterbox challenge

The Block’s Sharon Johal and Ankur Dogra suffered another blow during Tuesday’s episode of the show.

The couple were the only contestants who failed to complete the challenge, which consisted of each team making their own letterbox for their house.

‘We don’t know what we’re doing,’ Sharon said as her husband screwed holes into the letterbox.

‘I don’t know how to do it,’ Ankur informed her.

‘It’s crap, it’s crap – but what can you do?’ Sharon responded.

Despite failing to complete the challenge, the couple still decided to present their letterbox to the judges.

‘This one’s, uh, minimalistic,’ host Scott Cam told judge Shaynna Blaze.

‘I was going to say, is it a disappearing one?’ she asked.

It comes after Sharon admitted she was ready to leave the show, as she struggled to complete her guest bedroom ahead of her second room reveal on Sunday.

‘I’m really not enjoying it, and I haven’t enjoyed it. This whole thing is so hectic,’ she said.

‘And then all I can see is my future, of 10, 11 more weeks of this. I used to be a really bubbly, happy person, and then a week ago I came on The Block.’

‘I want to leave! No hot showers, there is no heating, mud … I do hate it here,’ Sharon told her husband Ankur.

‘We’re going to have to figure it out. I think we leave,’ Ankur responded.
