General design guidelines: 

  • The bathroom should be ideally located on the north of the house.
  • The ideal layout should make the most of the available natural light and natural ventilation.
  • In multi-storey buildings, bathrooms should be located one above the other. By this, the cost of plumbing system is considerably redused. 
  • Adjoining bathrooms, but of different appartments, should not share the same plumbing and the same ventilation system.
  • A bathroom is a humid and wet place. Thus, all surfaces should be cleaned easily and prevent mold growth.
  • Floor surfaces should not be slippery.
  • The bathroom should have at least one schuko socket.
Apart from the basic fixtures, bathrooms also have furniture, like: 
  • Cabinets and drawers for towels
  • Cabinets for laundry
  • Mirrors
  • Shelves, drawers and cabinets for personal care products
  • Radiator
  • Other accesories

Typical bathroom layouts 

Half bath / powder room

A powder room is a small bathroom with a small vanity or sink, mirror and toilet and is designed to accomodate guests as well as family members.  This type requires the minimum space for the essentials, though is suitable for restaurants, cafeterias, shopping malls, etc. In many homes, the closet or space under the stairway is drafted as a powder room so visitors don't have to go upstairs to visit the main bathroom.

 Before renovating any room, including bathrooms, kitchens, living rooms etc., you have to measure the dimensions of the room. Then you have to make a draft sketch of the floorplan.

A great tool to use is certainly the ruler and the graph paper. In the market you can even find a specialized graph paper notebook, ready to use for any technical drawing at 1:50 scale in metric unit system.

Graph Paper (1:50 scale / metric system): for Architects, Engineers & Designers is certainly one of the smartest and most practical tools for architecture and design drawing. It is a grid paper where you can draw directly, even without using a ruler, any floorplan at 1:50 scale.
