When folks ask us what was the most challenging aspect of building a tiny house we will chorus in unison: BATHROOM. Several factors made this the most difficult part of construction.
Firstly, this is the room we spend the least amount of time. For Cedric, this meant that finding inspiration to work on the bathroom was not easy. It was more interesting for us to design and build the kitchen where we spend the majority of our time. Secondly, designing a bathroom on wheels is challenging in and of itself. We love tile but the fact that the motion of moving the house would likely cause cracking and/or breakage threw that option out the window. We tried buying a shower pan but nothing fit our tiny space. We looked to RV and boat design but we wanted as little plastic as possible and much of those use plastic to create a waterproof space. We considered using a hardwood such as teak since it was available through the warehouse where we constructed, but we feared it would be too heavy. Our bathroom is on the tongue side of the trailer and we didn’t want to weight it down. That was another reason for throwing out the tile idea-too heavy.
Finally, we decided on corrugated tin which was light and attractive. Before installing the outer materials the walls and floor were painted with reclaimed, heavy duty marine paint that’s used on ships to prevent water damage. For the flooring we decided to make a stainless steel shower pan. Cedric found the material at a junkyard. It was previously a kitchen counter but Cedric shaped, cut and welded it to fit our bathroom space. This is where our community came to our aid because we did not have the equipment to reconstruct the stainless steel counter top. We wouldn’t have been able to accomplish it without the help of our friend Bill who has a machine shop. It was not a cheap option and it took a lot of work to get right but we don’t regret the time or the money spent. Our bathroom will probably outlast the rest of the house!
Once we had installed the tin and pan we noticed we had issues with standing water. We fixed this by banging the shower pan in around the drain allowing for better drainage. We built in a box on one side with a hinged lid where our bucket composting toilet is located. We heat our water with an on-demand hot water heater that’s propane powered. It works like a charm although we did have trouble keeping the flame lit on a very windy night!
The bathroom, or the wet room as we call it, is still not quite finished with one window left to trim but other than that it has turned out to be a great space. We created a drainage field based on a gray water system we had used while working on an organic farm. It allows us to water our plants while showering which our banana and pineapple plants love! We are careful with the products we put down our drains using biodegradable soaps and shampoos that won’t harm the soil or plants. If comments on our garden are any measure of success than we hit the nail on the head. Of all the gardens I’ve had in Charleston, this one received the most praise from neighbors. I definitely think the extra watering had something to do with that! Ultimately, we’d like to build an outdoor shower for summer months as well as a possible outdoor kitchen but we still have a few months to consider those options!
