Pankaj, I just realized that initially you told us that the bathroom area was 12'-0" x 9'-0" and later you mentioned that it was 11'-8" x 8'-0". In the last floor plan, I forgot to change the bathroom with the new dimensions. Below is the floor plan with the correct dimensions for the bathroom. The bedroom is ok, I drew it 19'-2" x 12'-6". The new layout does not change the way things are placed. Everything still fit. The only difference is that the vanity is now 4'-4" long instead of 4'-8". and the toilet is closer to the shower by 1'-0". Can you give me the lengths of the walls K and L. They are the walls between the vanity and the shower area. I will send you the new layout once you give me the length of these 2 walls.

It's a bit hard to tell, it looks like some of the proportions are not correct. Given what you have drawn it looks like entering and exiting your shower is going to be awkward. I'm not certain that you'll be able to open the door all the way because of the placement of the tub and vanity. Here are a few suggestions: Ditch the corner tub, and use a rectangular one that is installed with the long end on the wall opposite the vanity and shower and install the toilet next to the tub. Slide the door to the right, and you'll be able to have a larger vanity and/or shower. If you can use a pocket door or something of the like you'll gain wall space like sandpat mentioned. I don't see any storage planned. Have you thought about where you'll keep towels, toiletries, etc-?

I'm not against colorful homes. There's bright, and then there's too bright. I wouldn't go with persimmon for the whole house. The photo you provided has lots of white trim which offsets the orange, but your house doesn't have that much trim (unless you were planning on adding some, which I think would look good no matter what color you ultimately choose, but even so, I wouldn't go with persimmon for the whole house, as it's still too bright). To repeat what @nwduck said, the other homes in the neighborhood don't appear to all be done in the bright colors, and so yours would stand out too too much. I like @deco's idea of the bright door, if you really love a bright color. For the rest of the house, any more subdued color would be fine, along with additional trim around the windows, and assuming that your siding color coordinates with your roofing color.

Some pics of the pieces would be good.30” tall is a bit low for a vanity so you will need to use vessel sinks for sure.
