Hard disagree. The only benefit I can think of from having the shitter and the shower in different rooms would be if you live with many different people and have bad time management.
A wetroom gives you much more open space, and it also has basically everything many people do in the morning: toilet stuff, brush your teeth, take a shower. An added bonus is that it's much easier to clean.
A classic situation... LEO had lots of this information originally (as well as people contributing to it - taking pictures of hotels/Airbnbs/etc), for being able to help pinpointing child abusers... but as usual, they can't stop moving the goalposts.
