What's the Flaw with This Master Bathroom Idea?

Good Questions

Q: We have a small master bedroom, but would really like to add a master bath. To minimize the sacrifice of bedroom space, I had been thinking of a fully tiled small room with a toilet, sink and showerhead/drain. No shower door or curtain. The only downside I see to showering in this way is sharing the space with a toilet.

I could easily make a folding cover for the toilet out of vinyl with hard plastic inserts that would just cover the toilet fully during showers. The point of the plastic inserts would be so that you could just remove them and wash the cover periodically. When not in use, it would fold and stick/hang on the wall. Another downside might be lack of storage space, but a couple of classic shower corner shelves would be sufficient; we have another bathroom where accessories, etc. can easily be stored. Why don't I see this idea implemented anywhere? What's the fatal flaw that I am not seeing?
