Mrudool, Changing to sliding window on the exterior may not work as it will be difficult to operate because of the grill. Or do you want to dismantle existing window completely and have a sliding one inside the grill ? That will be better for air circulation. Existing one seems bad on ventilation. Thanks, Nitin Cornerstone Designs, Bangalore.

nowdays so many design in upvc window with exhaust fan hole

Hi Farooq, you should go for wall paneling on that wall with a concealed door. The wardrobe can be a part of the unit in front.

I have the same kind of bathroom and saw the same video. I used an angle grinder to remove one of the walls. You have to have hearing, breathing, and eye protection. I don't think there is any way to avoid the dust. I'm going to direct a fan to an open window in the bathroom. My sinks are top mount so there was no problem removing it. I replaced the faucet only for now. I also changed out the drain and stopper. The old one was rusted to the sink. I had to bang on it with my loader from my tractor with the sink upside down to get it off, lol. I have put off removing the rest of the wall and the cabinet because it is such an ordeal. You might check with Daltile to see if they still make the tile. Maybe try cutting away the cabinet while keeping the counterop supported and then dropping it so that the joint gets more exposed? I'll be interested to know if you get to this before me but I'm doing an entire gut job.
