Once upon a time I shared a peek at my frugal shower, and I wanted to share other aspects to my frugal/green bathroom.
I've got a crowded toilet tank--Adding items to your toilet tank displaces water when your toilet fills, resulting in less water used per flush. We already have a low flow toilet, but I have added a 1 liter bottle, a brick, & a hang it & save pouch my mom gave me from Scott toilet paper. Even if you only tried one of these items, you would be saving water & money, while getting the same necessary flush.
I don't buy air freshener--I know a lot of uber green people suggest not using air freshener at all, but it's better for my marriage if some smells are covered up. ;) Instead of buying aerosol cans of air freshener or matches, I've begun using my unused body splash. It only requires one spritz, so it last a long time, & I'm using up stuff that has just been sitting around. Win, win.
I've minimized the cost of paper products--I've started using my Swagbucks to purchase toilet paper made from recycled paper. It's great for the environment & because I'm using my swagbucks, it's a help to our budget. Additionally, I use hankies when I'm at home instead of Kleenex & have cut my consumption entirely. I've had that little sample box of kleenex in my bathroom for months & I've yet to use a single tissue. I still have to keep some on hand because JC uses at least a box per cold, but at least I've cut down on my usage.
I'm always trying to find more ways to cut down on our budget & footprint, & I'm finding the more I think about it the more ideas I come up with. I just don't know that I'll be buying a composting toilet any time soon...
