I sketched the relationship between the functional spaces and the windows. I was based on the need to link the windows to the bathroom space and the emphasis on connectivity. A fourth option was finally chosen as an extension of the design.

The first point of the design is the extension of the windows, which are L-shaped to give more views and let in more natural sunlight. So the window design creates a connection with the outside world and allows the raw material from the outside world to have a relationship with the bathroom space through the glass material; this design is a connection and an exchange.

The second design point is about the arrangement of the functional spaces inside. This is because some functional areas need privacy, and others can be kept open. The functional areas I wanted to include were the shower area, bathing area, toilet area, vanity unit, storage, and greenery area.

An exciting aspect of the design is the positioning and the connection between the windows and the functional areas. For example, in the shower area, depending on the function of the shower area, a window is located on the left side of the shower area, and a partition is used on the right side to distinguish the shower area from the other regions. The shower area is arranged in a corner without windows above and to the side, so privacy is important, but also glass and steel materials are used to connect the shower area to the bathing area. The toilet, for example, is positioned on the other side. To the left of this is a place with plants, which not only provide an effective partition between the toilet and the shower but also give the bathroom a little more life. The window design brings natural light and exciting shadows into the space and provides the plants with plenty of sunlight.
