An essential part of any bathroom!
What is a water closet? It’s characteristically a room within a bathroom with a toilet where you can do your business in peace, closed-off from other’s who might be brushing their teeth or singing to their favorite tune in the shower.
In other words, a water closet is a godsend to anyone who’s forced to share a bathroom and dying to carve out a bit more privacy (because after all, doesn’t everyone deserve some alone time now and then?).
