If you want some natural light you could run some transom windows across the top of the bedroom wall but there are lots of bathrooms that have no natural light and are lovely.

Sir, we would advise you NOT to go with this. Even suggest to re-think about black and grey theme for the bedroom. It may look good in pictures but they are inherently gloomy and not considered very good for residents. Thanks, Nitin Cornerstone Designs Bangalore

You should broadly follow Vaastu as long as it doesn't upset the entire rhythm of a living space. There is no point in following all the diktats of Vaastu and finding it impractical when you are actually living in the space. It will be a constant source of irritation and THAT negative energy is far worse to live with. In my career I have found Vaastu consultants who also disagree with each other

Client loved wood as their primary material. We created this room with teak wood flooring and earthy tones on wall with space divider which also works as an extra seating space.
