Answer: In Season 9, Episode 20 of "Mythbusters," Adam and Jamie tested whether a person could survive a "toilet bomb" (recreating a Lethal Weapon 2 scene) by jumping into a cast iron bathtub and being covered with a bomb blanket. They used 1 kg of C-4 explosives that created a blast with a peak lethal pressure of 180 psi outside the tub. The pressure inside the tub was recorded as a survivable 8 psi, though with probable hearing damage. From what I read, a grenade has a much lesser psi force than what the C-4 explosion produced. Depending on the circumstances, it seems plausible that a person could survive the force and shrapnel while inside the tub.
