Saturday and Sunday we put in a lot more work on the bathroom. Saturday was mostly filled with chopping off more tiles / cement and getting building materials. We were pretty lucky with the tiles (cheap!). Getting the copper work and piping did take a long time though 
It felt like we waisted half a day, but that’s silly of course: that stuff has to be bought.
We wanted to stop at 1300 on Sunday. The plan was to get the new 110mm pipe up. That required (a) getting rid of some old pipes, (b) digging up the sewer pipe in front of the house and (c) making a large hole into our basement to connect the two. The last step was damn hard. It took us most of the Sunday (until 1400!). We’ll do the rest of the breaking next week I suppose. Stay tuned…
