Bath room next to Master Bed Room

Dear Master Lee:
I am living in a 5 room flat. We have two bath rooms in our house. One is
near the dinning hall & the other is in
our Master bed room. My queries are pertaining to the bath room near the
dinning hall.
1) The design is that this outside bath room has got two opening folding
doors which allow us to walk thru' from service balcony to the long corridor
leading to the master bed room & vis versa. Whenever we need to use this
bath room, we need to close both sides of the door. My question is: I've
heard from my relative that this two opening (folded door) will lead to a
hazard to our marriage life either led to divorce situation. Is this true?
If true, how to remedy it.
2) This bath room is also considering located at the center of the house.
I've read from your feng shui web site that it is a bad feng shui if bath
room/toilet is located in the center of one house. Any remedy?
3) We have to close one side of the folded door (the one nearer to the
dinning hall & leading to the corridor which led to my master bed room) in
order to cover the unsightly of the toilet bowl when ever we have our dinner
at the dinning table. What's the bad feng shui impact if the door is not
closed and we can see the toilet bowl?
4) We have been staying in this house for about 7 years already. So far
there isn't good money luck i.e. strike lottery or happy occasions since we
have moved in to this house. Wondering whether if this bath room causes the
bad feng shui, what is the most suitable remedy other than to seal up one of
the folded door.
5) My daughter is often sick. Wondering whether this has also got to do
with the bad feng shui of this bath room/toilet.
6) I notice that both my husband & myself have several quarrels too over
some minor things. Wonder this has also got to do with the bad feng shui.
7) Since I've moved in to this house, I've not been able to conceive through
3 - 4 years of attempts.
Your advice is appreciated.
