Forget the frameless shower door trend and try this cozy idea

Arched entryways offer a very unique look as the size and smoothness of the curves easily create a cozy atmosphere. An arched shower entryway is a great way to have a focal point, define the area and make it a little private while the glass cladding maintains an open feel. You can incorporate this design by getting doors with built-in arches or an arched wall if you have a walk-in shower. Fortunately, you can DIY an arch with foam if the existing wall is already there.

With this concept, use color and texture to create as much definition as you want. One way to highlight the arch is to create a dark wall on the exterior paired with a light wall inside the shower area, or have a light wall on the exterior paired with a statement backsplash inside. Having an outline on glass doors can also add more definition. You can even make a statement with the interior side of the arch by adding an interesting tile as well.
