I probably would hang some fabric panels from the ceiling by the half wall that could block the light, but could also slide all the way to the wall to close the whole area. They could be left open/stacked by the half wall when you don't need the light blocked. Maybe slide them into position at bedtime, so in the morning they are ready to block the light. Ikea has great systems - very affordable. These might not be opaque enough but I'm sure they have some that would work.

I agree- building the wall wont make the room feel smaller- it will just make it more functional and less awkward. i don’t think you need to remove the door to the shower area either. keeping it gives you additional functionality.

That wall is begging to be built.

-You can build a wall with a pocket door or that swings inward

-if you tear down the other wall you can turn the vanity around so the back of the vanity is against new wall and you may be able to recess the wall so you gain space but it might be awkward looking

You could out bed on another wall why don't you tell us the dimensions of the room not including vanity area so we can better advise

It's 10' 6" by 13'ish

First I would flip the bed. The head is even with the lighting so ya it's going to 'be blinding'. Meanwhile start saving money. That entire space, bathroom/closets/bedroom needs to be gutted and reworked.

Test out your thought. Take a sheet or paper and tack it to the ceiling. See how you feel about it. Try putting the bed on the other walls ( although not sure if it would work ) and see how you feel.

You could also try just closing up the half wall. It may help with the light.

I do really like Olychick's idea a lot too

Personally, I would close the wall. Bedrooms are cozy spaces anyway.

Looking at your pics again, is there room for a small sink opposite the toilet, inside that room? Just big enough to brush your teeth, etc. when someone else is still sleeping.

Build the wall that set up as is will always make you crazy. If you post an actul to scale floor plan of the whole space here on graph paper you might get some real help. Post here showing every window , doorway and measurement clearly marked that in cludes the bathroom . Post in jpeg format in a comment here DO NOT start another post.

If you need a small-budget solution at the moment, install a sturdy ceiling rod for floor length heavy blackout curtains that would run from door frame to wall. You may need an extra valence board to block light leakage at the ceiling.

Also, It may be possible to install a dimmer switch (under $30) for the vanity lights. There are LED bulbs that are dimmable and those that aren't, so take a look.

You need the wall. I wouldn’t hang anything. As Patricia points out, give us the floor plan with measurements.

Once we come up with an adequate plan, you can show your husband.

Sometimes it is hard to visualize.

The first person getting up should use the guest bathroom.

If you build the wall, would you also consider changing the vanity itself? and the mirror and lighting? You need accessible storage there. A vanity with drawers, and a recessed medicine cabinet. Maybe two, one on either side of the vanity.

That is a small bedroom. We had 11x13 with an ensuite, and I definitely would not have wanted the sink in the bedroom. Make a proper ensuite out of that, really. Who wants to see bath towels in the bedroom?

Re-orient your bed, close off the wall where the sink is and add a door. Then demo the wall/door between the sink and the toilet/shower and make it one large bathroom.

Is your house on a slab or a basement? I would build the wall, move the vanity to the opposite wall, and put the door where the vanity is now, to minimize the walkway needed to get to the bathroom.

Though Olychick might have the best solution - put a small sink/vanity in the toilet/shower space, and turn the existing vanity area into closets. One doesn't need a ton of vanity space if there is a nice closet right outside the door.

The blue is new walls. Remove the yellow X walls. On the left, where the towel bar is, add storage, whether a linen closet or, even better, lower drawers, then a bit of countertop, and cabinets or shelves above. New vanity on the right with drawers, although, you could forgo that for now. new lighting. Medicine cabinets.

Now you have more room in the bedroom for nice pictures on the walls, and you can store more stuff in the bathroom. and it feels less like a motel.
