Here’s mine: Replace your shower curtain, and you’ll feel like you have a whole new bathroom.
If you're having guests over and you only have time to clean one room, make it the bathroom.
Almost everything in your bathroom comes in standard, boring colours. White toilet, black plunger, some beige kind of cabinet under the sink, towels that used to be some interesting colour before you ran them through the wash a hundred times. But your shower curtain can be anything you want.
A shelter from Fallout, a tasteful blue ombre, a decadent tassel curtain, Disney princesses, drawings of sea life, a sailing ship fighting the Kraken, or a map of the world. Alternatively literally any picture you have handy can be your new shower curtain, because CafePress does shower curtains for $US45 ($63).
All the curtains above cost $US70 ($98) or less. You can pay more if you want, but don’t. A shower curtain doesn’t really have to do anything. The liner is doing the work. All that matters is if it’s opaque or transparent (for privacy or light), and if it looks nice.
This is the bathroom equivalent to painting or papering one wall. Because it’s not every wall, you can choose a more dramatic or busy design. It doesn’t have to last forever, but do throw it in the wash when the edges get grimy.
While you’re at it, get some nice metal curtain rings and replace your moldy liner. Now give the bathroom a quick clean, throw out your expired medications, make the rest of the place live up to that curtain. And never do anything drastic like replacing the fixtures or painting the walls without testing that one little change: A fresh, clean shower curtain.
