Draft proofing and partial internal insulation
The next project was to do with the bathroom. It was cold and draughty. Some of the tiles above the bath had popped and allowed water from the shower to flow where it was not wanted. A temporary repair had been done, but it was not ideal. Also, David is tall, and the roof is sloping. Time for a change. Reduce the drafts, insulate, and move the bath shower into the room to increase the height.
