So, it's time for a restroom summary:
The bathroom is a little under 6' x 6'. Like the bedroom partition, the bathroom walls don't reach all the way to the ceiling. Though we needed privacy, we wanted the house to feel open and light.
Our shower has an off-the-shelf 27" x 54" pan. We covered the moisture-resistant green board in the shower area with galvanized, corrugated sheet metal attached by roofing screws with waterproof washers. We overlapped the sheets to prevent water from getting behind them and sealed the corners with silicone caulk. Our nice, big shower window lets in a lot of light, but we didn't realize it would get splashed this much when we shower. So we added extra-wide, painted trim around the window, and we wipe the wet sill after we shower. (So far, so good.) Our Delta shower head is a low-flow model, but still produces a good, solid spray. Rather than heating water all day, we flick on our 12-gallon water heater 30 minutes before shower time, and get a good six minutes of hot water. Not a long shower, but long enough! You'll find more on plumbing here.
Our tiny, wall-hung sink is deep enough to make hand washing and tooth brushing convenient without taking up much space in our compact bathroom. After a lengthy search, we found our pint-sized Barclay sink online at Home Depot. We went with a Delta faucet on the sink.
Our composting toilet may not be as convenient as a traditional flushing model, but we've adapted quickly with no real complaints. Nuts and bolts: The toilet seat is an Ecovita Privy 501 with a urine diverter, which means Number Two stays drier and therefore less smelly while Number One flows down a pipe through the floor to a gas can under the house. The diluted urine can be poured out anywhere and used as an effective fertilizer; we chose to pour it a distance from the house. Two 5-gallon buckets sit inside our DIY cabinet. One we line with BioBags, fully compostable liners that we will eventually be tossing into a yet-to-be-built "humanure" composter. (For now, the poop gets "wasted" by being tossed in the landfill. We need to get on this project!) Each time we make a deposit in the bucket, we scoop up some coco coir from second bucket to cover the poop. (We use coco coir, because it's considered more effective than sawdust and it's more sustainable than peat moss, the other "cover" options.) For more info on composting toilets, you can't do better than the Humanure Handbook. We also found the Gone with the Wynns website handy when figuring out our system.
Our door is a hanging barn-style DIY model scavenged from local demo sites. More here.
Our 9-inch-deep medicine cabinet is set into the utility closet behind the bathroom. A hinged mirror covers it. More here.
Our floor is the same tongue-and-grove pine we installed throughout the house. We used a waterproof stain and have a rug to sop up any shower drips.
The light is an outdoor fixture by Design House that seemed to fit our bathroom style better than traditional bathroom lighting options. (It was also cheaper!) Like the rest of our lighting, we're using an LED bulb. It should last around 20 years and uses very little power.
Our towel hooks, towels, soap dispenser, shower curtain, rod, rug and shower shelf are all from IKEA. They don't pay me to say this: IKEA showrooms are a great place to cruise for tiny house ideas and their products fit tiny budgets like ours.
What's not in our bathroom yet: a vent fan. We bought one, and it was so big and so ugly, we returned it. We'd like to figure out an affordable, compact way of bringing fresh air into the house and venting out any bathroom moisture and smells. Still in the works....
