Image too small to see and we would need more information about your wants and needs.

Can you put the toilet in a water closet? Looks like u have a ton of space.

Are you willing to move any plumbing? Can you us the layout of the adjacent rooms?

Do you have a larger image? I can't really make out what the layout is. I see some LED lights and exhaust fans I think but the rest is very hard to see. Keep in mind that the exhaust fans require ducting that goes to the outside. It can't be tied in to the ductwork for the air conditioning as it will contaminate the air with moisture. You also need to make sure that the plumbing drains and vents have somewhere to go. I wish I could see the image better to give more info. I think your toilet is in a small separate room? It will need to be at least 36" wide from wall to wall and the toilet will need to be a minimum of 15" from center to finished wall or wall-mounted obstacle. So if you have a tp holder on the side that sticks out, you will want to move the toilet over a little to have room. Are the measurements in cm?

magic of cropping

It may help you to google line-drawings of various fixtures (like toilets) and such to paste in to images to help give a better 2d visual of the floor plan. Or you can use MS paint and use the curved corner rectangle for the tank and an oval (circle tool) for the bowl. I'm having a hard time visualizing it like this, but then I'm better with photos than with blueprints.
