I was proposing this simple bathroom for small family in Solo, Indonesia. They just love to have full sunshine on their bathroom.
Slideable roof is an option, weather they feel free to have un-roof while taking a bath naked...whoolaa.. :)
Also to have more space feel, single theme wall and floor may help.
By the way if you saw the lavatory there it was suppose to be hand made. Yea we have team to made it happen, as they were commonly produce stone artefact near Borobudur temple.
I'm planning to have this post continues as building those bathroom will be in progress as soon as possible. So, see you around.
So here is it....
First steps:
Normally it will takes 3 days to replace old structure as it was two separate room, that is kitchen and bathroom.
