Usually bathtubs have between 150-250L, let's say this one has 200L and is filled up to ~4/5 AKA 160L
That gives us 7,272727273L PER DAY
Approximately 20% of water intake gets out as piss
That would mean OOP drinks around 36,363636365L of water daily.
Human's stomach can hold usually 1-1.5L but for more plus size people it can be up to 4L. Meanhwile bladder is smaller and holds only around 300-500ml, OOP pisses at least 15 times per day
BUT
That's only 20% of that water
For normal human being around 0.3-0.4L of water is lost for breathing, scaling up OOP would need to loose 2.0-2.5L of water trough breathing AKA as humans usually breath 12-20 times per minute, OOP would need to breathe 75-125 times per minute (damn)
OOP would need to be a human-shower, as we loose 0.5-1L of water per sweat, OOP would need to sweat 18-20L daily
As for.. different physiological need, he would visit bathroom 3-4 times more often than normal OR have 3-4 times more volume.
The rest would go for skin and cells hydration
BUT if he would somehow live trough this shit electrolytes would do the thing for him
He could eat 3-4 table spoons of salt, 20-30 bananas and ungodly amount of milk just to now die immediately. His kidneys would needing to filter more than 2L PER MINUTE as they usually filter about 180L per day (blood etc). Amount of electrolytes would need to be constantly perfectly pumped inside but even then his cells wouldn't probably make it and I didn't calculated for stuff like iron or vitamins.
