Have materials cut at a home improvement store and consider using style of door casings in home as inspiration for the look of the mirror frame.
Putting a frame around an existing mirror.
You can use this method to put a frame around a mirror that is already attached to a wall or to frame a mirror before hanging it.
Cut the corners on the frame square if using plinth blocks or at a 45 angle if mitered.
If the mirror is attached to the wall with screw clips either notch out the frame to accommodate the clips or remove the clips and attach the mirror to the wall with construction.
I have been wanting to frame my bathroom mirrors since well forever.
I didn t have clips on my mirror but did have a countertop on the bottom to work around i decided to make my boards overlap on top of the mirrror a good bit.
Use measurements to cut lengths of primed mdf baseboard.
Since even before the powder room remodel it seems like such an easy diy that practically anyone could do and makes such a dramatic difference.
Measure the outside dimensions of the frame so it overlaps the mirror.
These types of mirrors are also known as floating mirrors or construction ready mirrors.
This method works for framing basic mirrors that don t have any kind of rim or frames around them already.
Since this frame is floating on not attached to an existing mirror already mounted to the wall a margin of overlap is left to conceal the edge of the mirror.
