Samantha Varga's only role and nude scene as of Jan. 2023. Ron Bonk said Varga, who played Betsy, answered one of the casting calls for the movie saying she had a minor interest in acting. Even after he told her the role required an extended full frontal nude scene, she was all for it, so he cast her. He said she was a lot of fun to work with. She hasn't appeared in another role since and it's unknown if she hasn't auditioned anywhere or if she just hasn't been cast by anyone.

Writer and director Ron Bonk stated that the film was conceived as a result of both a desire to make "a shark movie" and an incident in which Bonk experienced ice cracking on the roof of his home. In an interview with PopMatters, he said "It was unseasonably cold even for mid-winter in Central NY, and I made a joke about it being zombies on my roof. And that was the movie title, Zombies on an Ice Roof, or something along those lines. Then I thought what if it was a zombie apocalypse but only inside people's homes... then thinking I didn't want to do zombies, I thought what if it was a shark?"
The special effects in House Shark were created by Marcus Koch and Matthew Ash. Over the course of about three weeks, Koch constructed a 14-foot shark costume out of foam latex. Several people performed as suit actors inside the shark costume, including Koch and Michael Merchant, the latter of whom also played the character Zachary in the film. In an interview with The Hollywood Reporter, Bonk disclosed that the costume has since been disassembled.
House Shark premiered at the Nightmares Film Festival in Columbus, Ohio on October 21, 2017, where it won the award for "Best Horror Comedy."
