If you pee in the bath..
Discussion
..does it get deeper?
There will be more liquid in the bathtub - but will your body now displace less? I don't want to perform an experiment unless I absolutely have to, so please PH scientists, help put my mind at ease.
A less disgusting example might be phrased like this: A ship floating in a pond is carrying a cargo of water. If the ship dumps its cargo into the pond, does the water level rise?
I would say Yes. Your body does not lose volume only fluid your bladder decreases in size in your body. When you pee does your stomach suck in? So you will fill up the bath slightly more.
Edited to add: That is for the pee example, For the ship example you need to consider Boyancy, A ship will sit lower in the water if it is heavier whilst a person does not float.

My understanding would be your body volume wouldnt change, unless you have some weird protruding bladder...
So yes it would get deeper?
ETA: Boat isn't quite the same because as it gets lighter it has a smaller displacement, and so more of it would be out of the water (in your instance the cargo in the water would have an effect and you'd have to account cargo volume and weight)
To conclude: It depends on whether your object is the same size in volume. In the bath i'd assume yes, in the boat i'd assume no.

Less disgusting example - no, it's displacement will match the volume of water it's carrying (plus the displacement for the ship to float)
In a similar way, if a towering iceberg melts, the sea level won't rise.
So this Global warming thing is a load of rubbish then?......In a similar way, if a towering iceberg melts, the sea level won't rise.

When you go for a number 2 do you think you lose that quantity from your external volume?
The answer is no.
So the level would rise.
You definitely lose mass with a number 2. Surely I'm not the only person who's tared on the bathroom scales before and after The answer is no.
So the level would rise.
What I did say was volume. So your point is pretty useless.
