Windows! And finished trim.
The front door is being built, so there’s a blank plywood insert to seal off the inside for now.
The windows in the master bath are glass block, which is why they look odd (they have a protective sheet on them for now). Glass block is nice in a bathroom – you get lots of light (the big one is about 4 foot square), you don’t need blinds for privacy, and it insulates as well or better than a normal window.
All the insulation is in; next step is drywall, probably tomorrow.
