Collection of Isometric line drawings for bathrooms

I need a collection of isometric drawings that will reproduce well in on simple black and white printers. So no color or shading. There will be 3 room layout drawings that should be from an angle above that will show the detail of the 3 types of bathroom configurations: 1/2 bath, 3/4 bath and full bath. (In case you did not know, a 1/2 bath has a toilet and sink only, a 3/4 bath is a toilet, sink and shower. A full bath has a tub. (some full baths have a separate shower - instead of the tub/shower combo.) Then, I want generic isometric drawings for all of the fixtures in the bathroom. Toilet, tub, shower, sink, counter, cabinet, mirror, towel bar, towel hook, toilet paper holder, etc. Each of these drawings will be used as representative for the "category" of product. They should be as generic as possible. No obvious manufacturers represented and nothing too modern/contemporary looking. What is important is that all of the drawings have the same look and feel. (Style). If they are all printed and laid side by side, they should look like the same person drew each one. I have attached a collection of 2D images and photos that represent these "typicals". I do NOT require these to be 3D, just 1 static view. BUT, if the software you use allows them to be easily converted to 3d, please let me know what this additional cost would be.
