Hi Zihui, just my 2 cents, I think your HTB has a point there. Even halfway through watching TV, running upstairs for the toilet seems a hassle to me. The kitchen looks big enough, and if your dryer and washing machine can be stacked on each other, it will take up only a small space. Place it beside the toilet, put up a wall made of board (forgot what it's called) to make nice nice. Cheaper than hacking the sanitary wares and making good again. haha
