My roommate put a scale in our shared bathroom and now I cannot ignore it

My roommate bought a bathroom scale and placed it between the sink and the shower. It is a sleek glass square with a bright display and, apparently, the gravitational pull of a small planet.

Before it arrived, I did not own a scale. That was deliberate but not dramatic. I prefer not to turn an ordinary morning into a data point. At medical appointments I answer whatever is needed, then continue with my day. At home, I want the bathroom to be where I brush my teeth.

Now the number is available every time I step out of the shower. I used it once out of curiosity, then again the next day to see whether the first number was unusual. Within a week, I had created a routine I never wanted. Nothing about my clothes, energy or plans had changed. The room had changed, and my attention followed.

My roommate uses the scale and has every right to own it. The bathroom is shared because our apartment has nowhere else practical to put it. Asking her to hide it might sound as if I am making her responsible for my choices. Saying nothing means the object continues to recruit me each morning.

I tried turning it sideways against the wall, but she thought I was tidying and placed it back. I considered keeping it in a cabinet, though the cabinet is full and the scale is awkward to move. A basket or towel over it would look pointed and become another thing to manage.

The conversation I want is simple: I am finding the visible scale distracting. Could we store it under your bed or agree that it lives in the bathroom only when you use it? I do not need to explain my body or ask her to stop tracking her own information. I need to negotiate where a shared-space object lives.

Is that a reasonable household request? How do you set a boundary around a wellness tool when the tool belongs to someone else but the visual space belongs to both of you?
