Mirrors should not touch the floor and should be fixed two feet above it. Does this apply to house mirrors too?
Yes, whether the mirror is in the house, the temple or anywhere else.

Can a mirror be fitted on a wardrobe in the S, SSW, SW, WSW or West?
No. Wardrobe mirrors also belong on the North or East wall. Some say the North-West is also allowed because the mirror represents the water element and the Moon.
Can mirror films be used instead of mirrors?
No. The darpan is considered auspicious and is used even in pooja; do not replace it with plastic films.
For a cut, should the mirror be fixed on the inside or the outside of the wall?
Fix it on the inside of the wall of the part you want to extend; seen from inside, that portion looks bigger and is extended. Fixing it on the outer side makes that part look smaller, so the outer side is used only when a part must be reduced.
For depth at an entrance in the North, is one big mirror better, or will design pieces do?
Use one whole mirror on the North wall. Do not join small pieces of mirror for a design; that turns mangal (auspicious) into amangal.
If the dressing room is in the SSW, can a mirror not be used there?
A dressing room has four walls, so fix the mirror on its North or East wall. If the wash basin is already in the South and its mirror must be there, fix a mirror of the same size on the North wall; the pit made in the South is matched by one opposite and the effect evens out.
Our mandir is in the Brahmasthan and Lord Shiva faces West; is that a problem?
Do not worry about Lord Shankar facing West; worry only about the South, and even Hanuman ji may face South. If a deity ever faces a wrong direction, fix a mirror directly in front of the deity.
