So for this to work, you need to go back through my question and make sure you have answered all of them the best you can. Is the electrical outlet for the counter space going to be right next to the switch, or is it that blurred spot that I see in the picture, . If your walls are Travertine marble, and there are not already electrical boxes in the exact location the lights go, we are going to have a hard time. If a 30" vanity goes in the corner, and you leave 5" on each side for the lights, that leaves a 20" mirror with one light jammed tight into the corner. So if we leave another inch on both sides, for clearance, that leaves 18" mirror. If you put a 3" frame around the mirror mirror, that only allows for 12" of actual mirror. I don't think that is enough mirror. Your bath is too narrow for a mirrored cabinet with built in lights unless it is recessed into th wall. The plumbing is probably in the way for that. Give me your thoughts on what I have just said, and then go back and answer all my questions. Then we can take it from there with a narrower down and focused search.

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-?

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.

I suggest you follow the step-by-step guide for creating storage cabinets under the bathroom sink. Take proper measurements - Measure the available available space in height, width and height. Cut Plywood to size - With a circular saw and framing square, cut all the required pieces out. You can use a sliding compound saw as an alternative. Attach the base and sides - Start assembling the sink cabinets by placing the bottom piece of plywood sheet on a flat surface. Attach the back and top boards - Place the plywood sheet for the top part of the cabinet and attach wood screws to connect it to both the sides. Turn the back faces of the cabinet upwards. Keep the back piece over the structure and fix it into place with wood screws. Attach shelves - Place the cabinet in an upright position to install the shelves. Slide a shelf into the structure so it is flush against the back. Attach door - Keep both hinges of the door on the same side of the plywood sheet. Drill them using wood screws into place. Now keep the door over the cabinet structure, extend the hinges to one of the side panels and fix them to make them secure. Fix a hasp closure on the other side of the door, placing it in the center of the hinges.
