I'm sure I'm not alone when I say that a visit to the bathroom in a restaurant can make or break my whole experience. I have been to many a nice place, visited the room out the back and come back with the whole dining experience marred by my experience of an inadequate or dirty, or just plain horrid, washroom. Conversely, I've been to some less than desirable establishments and been pleasantly surprised with what they have to offer out back. A toilet trip can make or break an experience.
This is true in your home. Think about it. Which room in the house do you spend time sitting down with little distraction? You have several minutes to ponder, gain head space, look about you. Closely. You are a target audience in your own home. They don't advertise on the back of toilet doors without good reason! So the toilet or washroom might be the smallest room in the house, but it's the one that has most of your undivided attention. It should therefore be the one that's looked after and decorated nicely, not to mention clean. If not for you, for your guests.
As you sit there you have time to see the whole room. Cracks, cobwebs, holes, dirt, uneven lines, gaps, drabness, flaky paint.... Absolutely EVERYTHING!! So if you're feeling down about the state of your house, I suggest you start by sorting out the smallest room of the house first. As often the smallest room, it's very easy to finish a total room makeover with the least effort (if you don't have to alter any bathroom fittings). Simple renewing damaged or incomplete finishes and materials, applying fresh paint and a mirror to bounce around limited light (which is often the case) will make a huge difference to your room and your experience within it. Having clean lines where one surface meets another with no cracks or holes is also critical. Seamless beauty and calm. No nasty surprises, spiders creeping out from under your skirting. You get the picture.
Adding a bit of humor is good too. But not toilet humor. That would be too crass. Wouldn't it?
If you don't appreciate your new beautiful small space, your guests will.
