I tried to change as little of the actual shell as possible. I didn't touch your walls, I swear. Just added a few. Boy, this was hard. I'm not a builder nor a designer - just a girl who's desperate for a nice spa. I included your roof tree becuase it happened to work. :) This is my hubs account, so you can find me @MeddlesomeWench on Discord and Twitter. #Plumhella
