As per the ancient vedic vastushastra, which I practice, the toilet, has no place in our house. But, This concept is unimaginable and would be laughable considering today's lifestyle. So, we have to give a proper thought to the placement and vastu of toilet.
A toilet placed in a wrong position in a house gives a rise to many sufferings and problems in life. The best position of toilet is in direction from West to North-West. If the toilet is in. the N to E direction then the dosha, gives rise to Financial, Health and Educational delays and problems. If the toilet is in. the SE to SW direction then the dosha, gives rise to Arguments, Fights, Accidents specially due to fire, Robberies, Financial and all types of instabilities in life. Having a toilet in master bed room is also a dosha which needs to be gives serious consideration and proper remedies.
Toilet should not be towards N, NE, E SE, S SW OR In the Brahmasthan (ie. Center)
The slope in the toilet should be towards NE or N.
Tap should be preferably towards E.
Outlet should be towards W or NW.
Person should face E or N while passing stool.
Toilet cleaning items must be kept on the NW.
Te color of the tiles etc. in the toilet should be in shades of Blue.
Considering all the above it is essential that Toilet is created a major dosha in the vastu and proper care should be given to its placement during the planning and designing of the house. If the house is ready purchased then, proper rectification of this dosha using proper remedies must be essentially don.
