I agree with divadeva. More lights. If you can add pot lights do it. If they're already there add task lighting and up the wattage on the bulbs on the pot lights (replace with LED and you can make them brighter because the wattage on LED is lower for brighter light). If you have all of that add decorative lighting. If ventilation is an issue find a way to move the air around or add air filtration. Maybe the HVAC is deficient. Maybe you can add a HEPA filter instead of the standard one that comes with the unit. Call an HVAC specialist to see if there is a way to boost air flow in the room.

Thanks a lot for your comment. I wouldn't exactly call it a walk in-closet. As you can see from the drawing, Its space provided for two single wardrobe (one on each side). Maximum width can be around 3.5 ft. The humidity point is quite relevant. The question is would it be possible to include a wet room in the space i.e. 6ft x 8.6ft. - considering I don't remove the dress wall. Wanted to get a sense on the possible layout. Thanks and look forward to your advise.

Ok thanks. After SE extention 1. NE was cut 2. SW was cut 3. water tank above toilet in center of east. 1. NE cut - Just make a shed/pargola of same height as bathroom... put 4 poles beside staircase and put up a tin shed. 2. SW cut... build a store room with 4 poles, tin shed, wall of plywood or/else any material you can afford. Door from east work area. Or door preferably from inside the bedroom. This is the bedroom in SW corner which head of the family or bread earner should occupy. 3. Water tank and toilet is not causing much problem due to height. However; I am not sure if thats exact center of your whole plot. Doesnt seem so. If anyone living there facing litigations, financial troubles or unnecessary authority problems... Just pay 500rs to a known good vastu consultant and amend accordingly. Its not practical to advise seeing pictures only, there are many things to consider. Thanks

I disagree with the advice above, the bathroom door that is in the passage should be closed. The reason for this is that you already have a bedroom without an attached bathroom. If you go by the advice above you will then have two bedrooms without an attached bathroom. Its not ideal. Also, you havent told us for which uses are the other two bedrooms. Are there going to be old parents in the bedroom with the bathroom or kids or are you going to use this as a guest bedroom? If you close the door in the passage you can have a bigger vanity by moving the WC behind the door that is from the bedroom side. This is also good because you should never have a bathroom door with a view of the WC. The WC is a very private spot and there shouldnt be a direct view of it from the room. Also we tend to spend more time sitting on the potty than washing hands, looking at ourselves or taking a bath. Once you move the WC you can have the vanity extending till the wall and will be 2.5x bigger than what you currently have.
