My understanding: You didn't find any problem functionally, but you feel this looks old & need some brightness & change in this. My advise: 1). Remove towel rod, shift it next to tub or behind closet & have full length mirror, which will make your space double & reflect natural light as well thus makes the space more bright. 2). Get couple of plants (small plants or bush type or creepers which doesn't occupy much space on floor but grows vertically). 3). Get some artifacts made from bright colored glass, can flower vase or wall hangings or glass tiles etc, these can be of yellow or Bright Orange color these are to be hung on walls opp to mirror or pasted(3M tape both side glued) if you are using tiles. 4). Get a mat of same color as artifacts & place between tub & closet. these all are easily done by yourself. OR if you can afford to then replace only green tiles & floor tiles if you wish to OR all tiles.

Just a quick note to thank you all for sharing your thought, ideas, experience and time. I especially want to thank Bluenan and decoenthusiaste for being with me through the all process for the last 6 months or so..., just wanted to post few photos of the results (https://www.houzz.com/discussions/any-ideas-for-final-touches-to-this-living-dinning-room-dsvw-vd~569586) as I feel it is not only me who created this space but it is your creations as much as mine. It may not be perfect or according to the the "Rules", but it is Me and my family. Each and every piece was chosen by me in different parts of the world and each one of them has a unique story behind. I am very pleased with my space. I love it! I am very blessed. .... and so I am off to my new project now... Back to school.... that's really going to be hard ;) Thank you all, once again.

Great transformation! The Wall Hung Units are really popular at the moment. They really increase the floorspace.

Beautiful bathroom! Fabulous Freestanding tub!
