We began the design process by picking a color and material pallet that matched the descriptions and worked well within the parameters of that which already existed.
Early on in the design process we took into consideration the small size of the bathroom. While the room is of modest size and maybe smaller than some contemporary bathrooms, the main issue is not to make it bigger, but to maximize the space for greater efficiency resulting in a perceived larger space.
We noticed the amount of walls breaking the small space up, making it feel even smaller than it actually is. We looked into which walls were necessary and which could be taken advantage of to open the space up.
A modernistic style would serve this room well as a style with more decoration/ornamentation (fancy trimmings) would clutter the eye easily and add to a perceived smaller space. The inherent minimalism in modernism would add to the freeing up of the space.
In the existing pictures we can see that the bathroom does support a large amount of storage. To minimize the effect of the storage on the feeling of the space, we decided to inset as much of the storage objects as possible.
A material and color pallet was chosen based on the project description. The black slate tile was selected to provide a raw, cave-like, natural feel to the bathing area. The wood was selected to compliment this natural feel and add an organic/softer feature. For furnishings we recommend allmodern.com.
