My workshop was a spare room that the last owner had converted into a laundry room, then into an office just before she sold the house. It was a MESS to get cleaned up, her handyman was clearly not very handy (horrid wall patches, and we've no idea what he used to adhere the carpet and linoleum, something sticky and waxy). But we gutted it, painted it a pretty light, but bright, aqua, added in some kitchen cupboards and a bar sink and lots of storage! I even have a door to the backyard with a tiny 4 X 4 deck for a chair where I can sit and read while my lye water cools!

Means less room for storage though LOL, same with the 2 windows.
I'll be doing a video tour of it soon, I hope. Still trying to get my husband to cut the last 2 4" pieces of baseboard, hang the last blind, and cut the last 4 1" tiles for my backsplash. But I've been waiting, uh, almost a year now I think. Soon I HOPE!
