I agree the creamy color needs to be changed. I would do a dark grayish/brown. Maybe you can use that same dark color on other areas too. A color close to the brown in the groves, as long as it is not too chocolate brown. Here are some ideas

You don't have to give up your beloved pink. Pink, brown and grey are doable. I googled pink and grey living room and saw some great pictures. Maybe get a large carpet that pulls out the pink (must match the same shade of pink). Then place your beautiful little pink and cream Kashmir(?) carpet over it. Also pull that same pink into sofa pillows. And a similar pink and brown Tablecloth for the dining table will pull the colours together. Just need to make sure all the pinks are the same shade with small accents/border of the same brown and grey from the sofa. Solid colours or subtle designs will be easier to coordinate than bold dramatic prints. These 2 are not the right shade of pink but you get the idea, I hope. Carpets with tone on tone pattern. A dusty rose on one wall would be nice too.

wodden pillar was extra thing ..might create hindrance ..jhoola is itself a divider.

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.
