Your decision depends on the style of your home. Does some type of wainscoting fit with the style? There are many type of wainscoting that could be used.

I think it's great you are trying to tie the spaces together.

Good morning,

yes, I think so? We live on a farm and going for a bit of a country feel. The second photo was about what I was thinking.

So, you think it should be in both the spaces and not only the bath, correct? Even if it’s not carried out anywhere throughout the house?

Thank you for the photos!

IMO there is no reason to add wainscoting to 2 rooms in a home where it is nowhere else. All the trim in the world will not make this a better layout so just keep the laundry room immaculate and maybe add some wall paper that runs through both spaces.I am not sure about your stlye but something like these that can transition from the laundry to the bathroom

Carefull on the height of the wainscoting. What works for the laundry room maybe a different height for the bathroom.

The second pic IMO is too formal a style for a country house. The other styles would work better and can be mounted at any height.

Well, perhaps I didn't express the style well. I didn't mean country as in cowboy.. More of a traditional country chic if that makes any more sense...

I'm evidently no designer but have an entire house to do and it's a bit overwhelming. We hired someone who ran away with her deposit, second woman who was going to do the kitchen layout/built ins/bathrooms and has her custom cabinet shop never showed up.

Only in the bathroom and laundry if the wainscoting is solid wood, some of that routed/styled MDF crap will just fall to pieces with the moisture otherwise.
