I know some people are under the impression that it’s necessary to shower every day. And for some, it may be. But whenever we can, we space showers out to once every 2-3 days (or sometimes more in my case, though not intentionally–being Mommy and all lol). We also use a water-saving shower head. Did you know most shower heads put out around three gallons per minute?! Ours lowers it to about half that. There are also shower heads on which you can actually shut off the flow while you’re soaping up (not losing your heat setting or anything else), then flip back on when you’re ready to rinse off. We don’t have one of those, but I’m sure we could save even more water if we did. Furthermore, we take quick showers. A “long” luxurious shower for me is about 10 minutes–usually I keep it to more like 6-7.
When we bathe the kids (again, usually about every three days, unless they’ve done something extra dirty), we fill the tub just high enough to cover the oldest one’s kneecaps while sitting–probably about 4-5 inches–and we either plop them all in together (which works at this point since they’re still pretty young), or bathe them one by one in the same water–in relatively quick succession so as to not lose too much heat. We’ve also done a similar thing with showers, one right after the other with the water running for about 15-20 minutes total (depending on how interested or uninterested each one is in being bathed that day). We have a corded shower head, which makes this even easier.
We only run the dishwasher when it is full. Same with the [clothes] washing machine. And we have a large capacity HE washer that holds the equivalent of two normal size loads, so that helps a lot too (especially with the amount of laundry we already do around here!). It can also cut down on power usage if you do a cold wash only most of the time—hot, or even warm washes, take a lot more power, and making your own detergent saves even more.
Now this is going to sound a bit extreme, I warn you–and up until previously, we only did this at night after the kids were in bed for noise purposes, since the bathroom is right between the bedrooms. But we now go with the bathroom rule so eloquently described in Meet the Parents (yes, this makes me chuckle every time lol): “If it’s yellow, let it mellow–if it’s brown, flush it down.” And no, we don’t do this when company is over. But when you figure each flush uses 3-5 gallons of water (depending on your toilet), that’s saving quite a bit! You may ask, won’t it get smelly? Not if you keep the lid down when not in use. And we just clean the toilet a little more frequently to avoid any rings or residual smell, and keep a make-it-yourself air freshener handy. :)
