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.

Based on the dimensions you have given and the religious aspects you mention you are very restricted in what the layout can be. The best solution I see means you have to move the door towards the south by 36". I suggest you make it a pocket door retracting towards the south wall. This leaves 36" x 60" of space on the north wall for either a shower or tub. The vanity would be on the west wall ( across from the door) spaced away from the tub or shower around 12". Make sure the vanity cabinet is shallow, no more than 21" deep. The vanity should be able to be about 48" wide. The toilet will go on the South wall with the right side of it close to the East wall. Code calls for approx. 33" of width for the toilet overall. If budget allows you could continue the vanity cabinets into the corner of the south wall however keep in mind that most of that area that will be next to the toilet and not easily accessible. But it would provide extra storage or counter space. The sink will have to be centered in the 48" part of the vanity. You could also frame out the southwest corner to capture the side of the vanity instead of a longer vanity. Hope this helps.

Cabinets by Design LLC if there is no room there, where would you consider placing the refrigerator? I would need some dry area (counter top) as well to keep my mixer/blender etc. also some space in the bottom for cabinets to keep all those big vessels for cooking. How to make use of the corner portion well? side - d? I have to think about the possibility Sativa Jaeger Designs LLC mentuioned , about moving the kitchen opening up further north. I also don't want want the kitchen door to be just opposite to toilet door . the kitchen door should start at the point where toilet door ends. I know this is a huge challenge, as it is really small and thats the only drawback of this house which we had to compromise considering all other aspects.

sorry to say but your plan is not showing in your post. Anyways please upload your plan and the main outlets of the bathroom, so that it will be easy for the perfect planning.
