The last bathroom remodels ideas for small house are separated-chamber bathroom. The basic concept of this idea is combination water closet / toilet and bathroom in one room. You don’t need to build wall as divider, instead of applying cubicle with door for bathroom or shower, and put the sitting or crouching closet outside. The ratio or comparison of the cubicle and the room outside (with closet) must be at least 2:1, because everyone knows that people need more space for bathing than sit and throwing some shit out. For the alternative, you can implement curtain instead of door on the cubicle as open and close access.
