Reuse an old tree to make a log pathway in your garden. Good use of "yard" trees and other wood that can't be milled; works much better in climates without termites. Good drainage under the log rounds will make the path last longer.
Tub in shower - kids can splash and swim as much as they want! Brilliant idea for adults too. Take a bubble bath and shower off at the end. Just step out of the tub and shower off! Great idea for future house! Master bath in bedroom.
