Cost of composting toilets

Many composting toilets use compost as a fertilizer which is great for your garden. The compost that collects in the toilet’s tank can be used as compost on your plants, or it can be stored and sold to other people who want to buy compost.

Composting toilets reduce water usage by up to 90% since they do not require flushing.

They are also more environmentally friendly than traditional toilets because they do not require chemicals or produce sewage sludge that needs to be pumped out of the house or sewage system – they only produce compost!

This blog post will discuss what you need to know about composting toilets before making a purchase, how much a composting toilet will cost and whether it’s worth it!

Why invest in a composting toilet?

If you already compost at home, chances are that composting toilets seems like a natural next step. And a great addition to the composting bin in your gardens or allotments where you already chuck your kitchen waste!

But composting toilets come with their own set of challenges and considerations.

Composting toilets have a lot of advantages: they use less water than traditional flush toilets, they’re better for the environment, and they don’t generate any sewage waste or smells from human waste.

However, composting toilet installation can be expensive (and sometimes not available), maintenance is more time-consuming (though not difficult), and there’s no guarantee your compost will produce enough fertilizer to grow all the plants in your garden! They still work out to be cheaper than alternatives like incinerator toilets.

Therefore, it is important to discuss and be aware of all the costs associated with switching to a composting toilet- although it can save money on water bills and utility costs, it typically requires more work than most people are willing to do.

Who should consider a composting toilet?

You are recommended to look into and consider switching compost toilets if you are keen on:

  • Saving money
  • Living more sustainably
  • Reducing water usage
  • Minimizing pollution and your environmental impact

Composting toilet systems to decide from:

Self-contained system:

The entire system is linked and, for all intents and purposes, operates as a single entity.

If you have a limited room or a multi-story residence, these solutions may be ideal for you.

Centralized system:

A big, centralized tank is built either under your home or outside, and all waste is flushed to the tank.

There are several types of centralized systems, each with its own method of flushing waste and a number of storage chambers.

Depending on your specific scenario, a centralized system, which is more comparable to a regular flush toilet, may give a better experience.

Compost toilet cost

Eco toilets typically range from around $500 to over $1500 depending on the brand and model you opt for.

However, you can DIY your own version for as little as $50.

When it comes to composting toilets, there are great products on the market now, with Nature’s head and Airhead probably being the market leaders.

Below is a list of composting toilet choices and their price and top features for you to decide from.
