Bathroom Design

Principles to keep in mind when designing your next bathroom

Posted on Sep 22 2017 by Martin Holladay

Americans who grew up in the 1950s or early 60s (that includes me) remember living in a house with one bathroom. There was usually someone standing outside the door yelling, “Hurry up!”

These days, most Americans live in (or aspire to live in) a house with two or more bathrooms. My guess is that we’re never going to return to the bathroom standards of the 1950s; two-bathroom houses are probably here to stay.

Toilet Talk: Meeting One of the World’s Grand Challenges

Forty percent of the world’s population lacks access to decent sanitation facilities

Posted on Dec 9 2015 by Karl Linden

How is it possible that 2.4 billion people lack access to improved sanitation facilities in 2015?

While many westerners use their bathroom time as “me time,“ 40% of the world’s population may be pooping outdoors, in an unsanitary latrine, or in a plastic bag and launching flying toilets to dispose of their waste.

Collection and Use of Urine

Human urine collection and use provide a better way to recycle nutrients than the use of composting toilets

Posted on Apr 3 2014 by Alex Wilson

Just when you thought it was safe to enjoy this blog over your morning cup of coffee, here’s an article on… urine?


Let me explain.

Urine is a largely sterile, nutrient-rich resource that can be used in fertilizing plants. In fact, according to the Rich Earth Institute, the urine from one adult in a year can produce over 300 pounds of wheat — enough for nearly a loaf of bread per day.

Does a Composting Toilet Stink Up Your House?

After three years of living with one, I can tell you the answer

Posted on May 22 2013 by Allison A. Bailes III, PhD

Ten years ago I was building a green home. It had passive solar features, was built out of structural insulated panels, sent all the greywater out to the back yard to water fruit trees, and was going to be super energy efficient. One feature above all others, though, captured people’s attention when I described the house to them — the composting toilet.

Can Switching to a Dual-Flush Toilet Save Heat?

The water that sits in your toilet tank robs space heat from your home during the winter — but is it a little bit of heat or a lot of heat?

Posted on Oct 2 2012 by Erik North

First off, my wife just joked that I used a photo of a “male bathroom”: seat up and two rolls of toilet paper.

Regarding the heat savings mentioned in the headline, we'll see... I haven't done the math yet. But it is a minor claim occasionally made alongside the claim that these toilets save water.
