Kitchen walls, living room floor corners and walls , and in closets and sinks and around the toilet bowls .

I've attached pictures of the current setup, my plumber wants to put them in the middle bedroom's closet (the one with the foggy window) but they would be sticking out a bit and I also plan on renting this house by the room so that could be a problem to have the laundry in one of the rooms.

Last year on a 1125 sq ft flip I added a 1/2 bath by expanding a useless 2nd story closet between the 2 upper bedrooms.

Also, tip I learned the hard way: when you install the digital keypad on the deadbolt above, consider replacing the doorknob below with a closet/passage knob--I kept the normal keyed knob at first, and twice guests locked it from inside and exited--keypad will work the deadbolt above fine, but doesn't do much good if the doorknob is locked! 

On the main floor there is a closet that has "sunk". 

How are the closets and room sizes?

A friend of mine who does kitchen/bath/closet remodels got me in touch with his stone guy and I got a new 3cm granite counter installed and the old one carted away for under 1k.

I'll try to enlarge closets and upgrade laundry areas and such.  

Cant buy a closet here for under 200K. 

I use the pax systems in the closets too.
