Options for Draining

For tiny houses on wheels, you have to have someone be that yourself or other family members who is willing to empty the waste. This procedure can be either draining the waste outside or the waste can be taken to the compost pile as well. But above all the willingness to empty the waste is the main requirement.

However, if you do not have a volunteer to do this cleaning then you should go for a traditional person choosing a traditional flushing toilet and making proper plans for plumbing and sewer hookups should be considered as an equally good choice.

Tiny Home Toilet 

To use the washroom in your tiny house you have to have water connection in your house. There are different ways to reach water into the tiny home toilet. Let’s take a look at a few of those. 

Collecting Water to Avoid Plumbing 

One of the easiest options of having water in your tiny home toilet is not having any plumbing system in your house at all. This won’t mean that there won’t be any water in the house. Rather the system will be devoid of automation that’s all. All you have to do is carry the water that you want to use at your tiny house toilet if you select no plumbing option.

If you are comfortable with carrying water to everywhere you need in your tiny house, then you will be saved from a lot of hassle that you had to do for plumbing. In that case store some water near the sink, store buckets full with water in your tiny home toilets.

To carry the water you can use buckets, jugs, or bottles. For all these you have to part your tiny house on wheels somewhere that is close to a water supply, such as a neighbor’s kitchen, backyard or even on a campsite. You can also save some water use by taking shower at your workplace, gym or school if you have that option available.

However, If you have no option to park your tiny house anywhere near a water supply, you should probably bulk buy water and select a place to store it. You have to keep in mind that one thing is very seriously precious in tiny houses and that is saving up space. So the option of storing water should never be inside the tiny house.

Certainly, the first and foremost benefit of the option is avoiding the hassles of dealing with any of the procedures that come along with plumbing. Also if you can avoid plumbing for your tiny home toilet then your tiny house might even cost a lot less than most of the tiny houses. However, it is entirely up to the owners or the dwellers whether the benefits of plumbing are more important than collecting water.

Tank and Pump

The possible most practical option for reaching water to the toilets of the tiny house on wheels is to put a tank into the tiny house and use a pump for circulating and pressurizing the water. Though this option is quite difficult for tiny house on wheels if the dwellers want to move quite frequently, this is yet the most effective option as this provides the functionality of a traditional house and also the advantage to have a tiny house shower, while still allowing the freedom of living off-grid.

However this option comes with some downsides too, but they’re definitely easily tolerable as well. The pumps can make a disturbance with their noise while they’re in use and the tanks take quite a fair bit of space. Also, the decision-making regarding the tank size can also turn out to be an issue as well.

The bigger the tank is it can contain more water but the size can also be space-consuming for the tiny house on wheels. Although a big water tank in your tiny house can look very absurd but you can hide it under kitchen cabinets or beneath the stairs. 

Keeping everything aside, the biggest negative side to having a water tank is that it needs to be filled continuously. If you want to flush the tiny house toilet, a tank might just not be able to hold quite enough water.
