Customers have to be over the age of 18 and must sign a liability waiver, although Mr Tan says there have been no serious injuries so far.
Many patrons agree it is a cathartic and therapeutic experience.
Entrepreneur Chris Chong, 28, says: "I'm not an angry person, but when you enter the room, you can release all the pent-up frustration.
"Singapore is a bit of a pressure cooker, so it's really good to just come here, let go and smash things up. You feel relaxed after."
Others such as Ms Sonia Teo, 30, were unsure about what to do in the room. "This is something we are never allowed to do in our daily lives, so that was holding me back," says the IT project manager.
Mental health professionals, on the other hand, believe that this might not be the best form of anger or stress therapy.
Clinical psychologist Jeanie Chu from The Resilienz Clinic believes that rage rooms reinforce the manifestation of anger. "The underlying message is that violence is an answer to one's rage. This conditions the self to be aggressive," she says.
Her colleague, consultant psychiatrist Thomas Lee, adds that the experience is a "quick cathartic relief of anger", but will not resolve the root of the problem.
Dr Lim Boon Leng, a psychiatrist at Gleneagles Hospital, recommends that those with anger management issues or psychiatric disorders seek treatment instead.
He suggests that rage-room operators put up signs or be trained to notice people who are excessive in their aggression and advise them on appropriate channels to seek help.
Still, Mr Tan believes that rage rooms offer the same release as, say, playing violent video games or engaging in martial arts.
"There are plenty of ways that could lead to aggression. This is a safe place for people to let loose."
He is well-aware that the hype might fade after some time and other rage rooms might open.
"There are people who just come for the thrill of it. We want people to make this a weekly session," he says.

Hurl and pound... and glad that I don't have to clean up the mess
Dressed in white coveralls and wearing a safety helmet and thick welding gloves, I look like I am about to enter a dangerous situation.
Holding a baseball bat, I enter a small room, where I see a crate of ceramic plates, cups, bowls, wine glasses and bottles in one corner.
There is a stand on which you can smash your desirables and a pile of debris sits against the wall. In the pile is a random car tyre.
I am at The Fragment Room, Singapore's first rage room, where utter annihilation is encouraged as a form of stress relief.
After a short safety briefing, where I am told not to hit myself and the furniture in the room, founder Royce Tan gives me just two words of instruction: "Go crazy."
It takes me a while to do so, though, as I consider myself a calm and non-violent person. You won't, for instance, catch me yelling vulgarities when a driver cuts into my lane on the expressway.
I gingerly prop a glass bottle on the stand and muster the courage to smash it to smithereens. I do so spectacularly. I laugh.
I realise I have always wanted to do that and it feels amazing.
Then I grab a glass and, despite all those years I've been told to be careful when handling glassware, hurl it with all my might at a wall.
All my pent-up frustration comes to the fore as I turn the room upside down. I think of the relatives who keep asking me when I will marry, as I obliterate a pile of glass again and again with the baseball bat.
To the taxi drivers who constantly ask me where I am from, to which I reply "same planet you are from", I get creative and stack up the remaining bowls before I throw all my weight into bashing them repeatedly into dust.
After a short 10 minutes, I am done with my crate of breakables, but I am nowhere near done smashing things.
I am energised even though I am breathing hard and beads of sweat have formed on my forehead.
It is as if a massive weight has been lifted off my shoulders from carrying a multitude of suppressed emotions of unhappiness and rage.
I spot the car tyre, pick it up and fling it at the wall.
I move on to the debris pile and start pounding what looks like the remnants of DSLR cameras, printers, laptops and kitchenware.
This goes on for another 15 minutes before I stop and look at the massive mess I have made. It looks like a war zone and I am glad I don't have to clean it up.
Perhaps I have an inner Hulk raging inside me after all. And now it looks like I have a safe space to let it all out every so often - and not get arrested for it.
