The existing pocket door for my master bathroom toilet compartment matched all of the other doors in the house. Not too exciting, so I wanted to swap it out with a frosted glass door to let in some natural light. I looked into options and found some nice doors that were inexpensive. Problem is they were designed for closets and were thinner than regular doors. More substantial doors that I liked were in the $300-$800 range.
I built this one using leftover 2x6s and 2x4s. My largest expense was $50 for the glass panels and I reused the existing hardware. A table saw is needed to cut the pieces to size and to cut grooves into the wood to hold the glass.
