Location of guest WC - entrance area?

Hello,
I have looked at a lot of floor plans by now ... and it is noticeable that the guest toilet is almost always located right by the front door. That means in most floor plans you have to go through the dirty area to get to the toilet.

I imagine it is better when the hallway/vestibule and wardrobe are directly next to each other and the guest toilet/bathroom comes only afterwards (towards the living area).

Are there good reasons for this ... why is the guest toilet/bathroom mostly located in the entrance area/dirty area?

Thanks & regards

Firstly, it is not dirty there. Why? Do you walk with rubber boots from the stable into the house? There is a back entrance in the utility room for that. And then, the wastewater must go away, so a toilet is best located on the exterior wall.

I think it is the easiest way for normally sized houses to run the wastewater under the slab as little as possible and to have daylight in the WC. If the WC is moved further into the interior of the house, both become more complicated.

We planned it next to the living area, so deliberately not next to the entrance. Exactly for the reasons you mentioned... The typical route is from the living room towards the toilet. Why it is done differently has already been said... It’s simply the easiest and often the cheapest, but otherwise makes little sense.

And yes, the entrance area of a busy house (especially with children) is always a bit dirty. At least we don’t take off our shoes at the door, nor do we let guests take off their shoes at the door and stand in the cold at first . And letting guests use the back entrance is also not really our thing...

The best place is directly at the front door. Discreet, easily accessible, usually the entrance is not in the south. Nothing is dirty there.

- practical and well placed from a planning perspective (e.g. drain, window, behind the toilet there is often the staircase, which otherwise fits poorly elsewhere) - inexpensive - how dirty is it really? - is a three-meter distance really problematic? - do not want to access my toilet from the living room or kitchen

Many reasons in favor of "next to the front door".
