because I also don’t want to be surrounded by three tiled walls when showering. I

we also looked at glass solutions for the shower/sauna,
super modern and very stylish,
completely open.
Just take some time to see how different options feel for you.

but I like the color May green, it always cheers me up. ;-)

True. A very refreshing color. About 10 years ago, I used it as Kiwi green in the kitchen, my mother had Apple green.

Since we will have light “wood-effect” tiles on the floors everywhere, free walls for nice pictures and space for large plants, and a self-built wooden washstand, I think it will be fine. We will decide on the color scheme for the non-tiled walls after moving in.

If it feels “fine” to you, then go ahead with it. The bathroom you want should be refreshing and invigorating, at least that’s my impression, based on the example picture you shared.
I think, at least in my case, a bathroom with an integrated sauna is more for winding down, so more relaxation than invigoration—and that is rarely achieved with white plus spaciousness; rather more like what @Nida35a has. Also, many accessories, pictures, and busy plants with small leaves tend to be lively and don’t provide coziness. Many elements need a “frame,” which usually is a fully uniform background color, not tiles here and there, picture frames or corners mixed with wallpaper—this usually appears restless rather than grounding. White/light walls open up the space (which is why small rooms are often advised to have white walls). The darker or more uniform the tone, the more relaxing and harmonious the atmosphere.
While many here seek a grounding connection to the bathroom, you are different. You focus differently, so the bathroom will also be “fine” for you—probably much more 😉 You will love it.

However, it is sensible to familiarize yourself with colors and spatial effects, textures, and surfaces—because often you live in a room yet constantly feel a kind of discomfort at the back of your mind—and then it is very likely that the design, without realizing it, is the cause. (Less likely is the man with the knife behind the shower curtain 😉 )
