This switchplate is so pretty! It would add beauty to any room! It is ready to install. I used stained glass pieces, beads and tumbled sea glass. Orange, yellow, blues, greens and purples make it just a pretty as it can be. The switchplate is a one toggle unit. You will notice that this piece shows the wooden edge of the switchplate. I really liked the way the wood grain looked with the glass and black grout.. so I left it! The switchplate is 5" x 3" normal size of a single light switch.
