Favorite room in the house to design or decorate?

I like big and comfy bathrooms. I'm very bad at building and decorating and I rather don't do those things myself, but bathrooms are the only rooms I do like to get creative with.

Sometimes when my Sims live in a tiny cheap house the bathroom is the biggest room with good quality items and flowers and candles in it. I like to pamper my Sims with soak baths in candle light.
