No. This WTPlus cabin is between doors 1&2. There is a toilet for the WTP passengers within this cabin at the back, just in front of door 2 left. Then after door 2, is the Club World cabin with toilets for the club passengers. The WTP passengers are far more likely to use the First toilets, as these are just in front of their seats. A closed curtain and some polite advice is given to save these toilets for the First passengers.
