A young lady recently asked me for some ideas on how to layout her bathroom. It was a long room and it was divided in half with a wall right down the middle that divided the bathroom. The other section of the room was just used as storage and was not utilised properly. She also wanted to intigrate her laundry area in there as well. It was an ugainly room with her shower located in another section of her house and she had no actual laundry to speak of. I suggested removing the middle wall and build a new one closer to the toilet. That wall is actualy just to support a two sided shower and house the plumbing utilities. Placed a few cabinets to house the washing machine and placed the shower next to it. The room now has good flow all the way to the vanity. All the space is used and is located in that one area. She was very happy with my suggestions and is making good progress in her renovation.

I strongly suggested to place a heavy duty ceiling extractor fan to get rid of moisture build up.
Actual location of toilet.
The shower wall need not be so high. It allows ambient light to pass at the top.
See how well the toilet is hidden by the shower wall.
