When the hubster and I moved into our new-to-us house, there was only a bathtub in the bathroom. The bathroom is designed such that short of major redesign and renovation, putting in a shower is impossible. There is a wooden storage cabinet right above the bathtub faucet.
However, there was also a shower in the basement. It had no shower enclosure and only an extremely moldy shower curtain. The cement flower is sloped so that the water drains into a pipe that goes outside. It is the same pipe that is used by the sump pump. First, we got rid of the moldy shower curtain. Then, we had to buy a new curtain. There were already rings. Well, when we finally got it all put together, it was not how I would usually take a shower, but it does work. I feel pretty confident that because I take pretty short showers (about 7 minutes or so), that we will use substantially less water and gas that we were with taking tub baths.
I feel great about this. Any "extras" that I see we would have normally paid towards our water bill I will put towards our challenge.

Just to be clear, we don't plan on keeping it this way forever, but we need to pay off some other debts first and fix some other things on the house before we begin to remodel the bathroom. After we replace the ceiling fan/light, we will start saving up to replace the four windows on the back side of the house.
