You may want to consider modifying the plan by switching the kitchen with the guest bathroom thereby creating an open space living area. Here are a few examples of open kitchen: Best of luck with the design! Feel free to write us if you have any questions.

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.

standard bathtubs take up space, look outdated and in today's busy life, rarely do we get time to use them. Better go for a high end steam shower with a bench seating if its within your budget. However, a free bathtub in a large bathroom however can be staggering. From my experience and the skill set available in our country better not attempt self made, it is quite demanding.
