What would you answer if you were to get this question? For myself I think I would say my bathroom, especially since we just redid it (promise will show before and after pictures). There is something zen with bathrooms. Especially nowadays when almost everything is possible. Why not sink down your bathtub in the floor? Beautiful mosaics can give it a luxury touch, n b the circular toilet. Double sink is a must if your more than 2 sharing a bathroom! Natural materials brings in the zen feeling. I like how they enhanced the window framing with the shiny mosaics. There’s no end to what you can use as a sink, here is petrified stone! If you’re bathroom is really small this could be a solution! As long as you don’t brush your teeth in wine I suppose this could work too!
