One time investment will give you years of joy and space :-)

just bring the service passage inside....make a bathroom and you can increase area of mater bedroom.

Splitting a common bathroom into two rooms can be a great idea if you need more privacy or functionality, but it really depends on your space and plumbing layout. Sometimes, expanding the master bedroom and keeping one larger bathroom feels more practical and less costly. Since you’re using the service area for modifications, check if it has enough space and proper drainage. From what I’ve seen with bathroom modification projects (like those done by Stair Ride Company), thoughtful planning around space and access makes all the difference, especially if you might want to add supportive features down the line. Definitely weigh both options with a layout pro before deciding!
