I would first consider whether these two events might be related. Young male cats commonly get a condition known as Feline Interstitial Cystitis (FIC) which causes extreme pain on urination and subsequently urinating outside the box. To Mr. Whiskas, it may hurt to pee in the box, so he looks for somewhere else to pee and finds the bathtub - it still hurts, but it seems like a solution to him in his kitty brain. You'll need to get Mr. Whiskas to a vet to get a urinalysis done, so that this condition can be considered. If you can pick up an oral medication syringe at the drugstore, you can potentially collect some urine yourself the next time he goes in the bathtub, and take that with you on your appointment - it may prove helpful on diagnosis. Identifying this condition early is extremely important, because these cats can experience complete blockage of the urethra, which is a medical emergency. And it's worth mentioning that painful cats are often aggressive, so this might explain his biting as well.
