For me, it's:
- emptying the contents of the small food waste bin into the large one outside. Fiddly and messy. Why do the caddy liner bags never fit properly and split so easily?!
- cleaning our pokey shower cubicle with it's annoying bi-fold door, mosaic tiles and miles of white (or it should be white!) grout! It was here when we moved in I should add!!
Am I overlooking something far more hideous but as commonplace though?!
