My space is strongly themed around a natural cave or watering hole. With this in mind, as the space transitions from day to night, I have kept the lighting very minimal.
There is a light in the entrance for bathers to find their way into the space and in the evenings a light under the refreshments area will come on allowing enough light for bathers to find the pool.

Bathhouse During the Day 
Bathhouse in the Evening
The soundscape of my bathhouse will be very organic. The open windows will allow birdsong, wind in the trees and the chatter of insects to be heard from the pool as well as the movement of water as bathers move at all times of day.
In exploring the effect time has on a space I went for a walk on Orewa beach at sunset. I observed that the dark brings quiet and rest to the beach. Even the birds and insects seem to go to bed. I found the quiet very peaceful and having such vast stillness in an open space was very calming. I will try and emulate this effect in my design by keeping the sounds that are heard organic, created by the bathers and the forest. I will keep the temperatures organic allowing the water in the main pool to be temperature controlled by the sun. I will also leave the windows open at all times to allow bathers to feel any wind that comes into the space and I will keep the lighting as natural as possible to allow the natural rhythms of the earth to play out within the space.
