I see by your spelling of the word "colour" that you are probably not from the USA. If you like the towels I selected, you might be able to purchase them online. A person from France mentioned that gray and mauve were a popular color combination for bathrooms in that country at the moment.

Something like this may work. Note the changed door positions so that anyone in the bedrooms can visit the bathroom without disturbing anyone else in the lounge !

Sorry but I don't understand your pictures. You are talking about 2 bathrooms but we see only one floor plan. Is the 1.52M x 2.24M the 5 x 8 bathroom in your dilemma title. If so, can we see the floor plan of the 5 x 9 bathroom? Is the space with a small rectangle in the middle the extra 5.5 x 4.9 ft space you mentioned in your dilemma? Also 1.52M x 2.24M is in reality 5'0" x 7'4". This is 8 in. less. It can make a big difference on how to place fixtures in a bathroom.
