And it won't be any ordinary stag do as the pair are hoping to invite a handful of their female friends too - renaming the event their 'Sten Do'.
We like your style, boys!
Speaking to The Mirror recently, Tom revealed: "We're calling it a Sten do - as it's not going to be all-male as some of our girl mates will be coming and I don't think we'd want to do one separately - we have a lot of the same friends."
It's not only his stag do that Tom will be bucking tradition with, as he also revealed he won't be having a best man, but a commitee of best men and women instead.
Finding the task of choosing just one of his pals to stand alongside him on his big day, the GB diver has decided to have three friends instead.
He added: "I haven't got a best man - more like a committee: my best friend Sophie and my cousin Sam and pal Mike. I'm not sure how it will work."
The GB diver has even been considering who to choose for his best man, and finding the task a tad tricky, Tom admitted: "I haven't got a best man - more like a committee: my best friend Sophie and my cousin Sam and pal Mike. I'm not sure how it will work."
Tom's latest comments come after he recently revealed he and Dustin will tie the knot in the UK.
Despite Dustin and his family being American, the couple have chosen to host their nuptials here, but will hold two celebrations both in the UK and across the pond to mark the occasion.
Tom also shared his wish to have a "small wedding", insisting he would find it awkward saying 'I Do' in front of crowds of people.
The 21-year-old also opened up on his plans to have a family with his screen-writer beau. Tom gushed that Elton John was an "icon" to him for bringing up his two sons with his partner David Furnish in the public eye.
Tom told the paper: "There's lots of gay couples in the public eye who are bringing up children now and it sends that message that anyone can have a family."
"I've wanted to have a big family ever since I was a kid," he said.
Tom and Dustin first announced their engagement in October last year. He and Dustin have been dating since 2013.
