Michael Weldon, in his "Psychotronic Encyclopedia of Film", called "Blood Bath" “a confusing but interesting horror film with an even more confusing history. Phil Hardy’s "The Aurum Film Encyclopedia: Horror" noted, “Cheap and crude, with echoes of a dozen movies ranging from "Mystery of the Wax Museum" (1933) to "A Bucket of Blood" (1959), this film isn’t unenjoyable." Cavett Binion of AllMovie wrote, "As one might imagine, this is pretty difficult to follow, but there are some good performances — particularly from William Campbell as the haunted shutterbug — and some fairly suspenseful scenes."
