There are a lot of misconceptions about the bathrooms in tiny homes. People are always surprised when they walk into our show model and see a full washroom. There are four main options for the toilet in a tiny home: composting, RV style, house style, or sawdust bucket. We've listed the pros and cons of each below, in order of most expensive to least expensive.
There are many options for where to buy a composting toilet, and they range from $1000-$2500+. They vary in the frequency with which they need to be emptied, their physical size, and the separation method of solids and liquids. There are even options which incinerate the waste for super easy disposal.
Pros: easy to use, resembles actual toilet, comfortable, minimal effort, no smell, compost for the garden, no footprint, no power
Cons: expensive, kind of big and clunky
2. Holding tank (like an RV - a toilet connected to an external tank)
Pros: actual toilet, comfortable, don't need any sewer hookups, can still be on or off the grid
Cons: uses some power, have to empty the tank in a proper disposal area, needs plumbing, holding tanks can be expensive, holding tanks add weight
3. Sewage hookup (just like a house toilet)
Pros: no maintenance or emptying tanks, just like a regular toilet, inexpensive
Cons: need to be hooked up to sewage line, required plumbing
4. Bucket of sawdust
Pros: virtually free, no hookups or power, takes up next to no space
Cons: requires frequent emptying, might cause some guests to be uncomfortable
