Tiny House Bathroom Design

As my tiny house construction progresses, I have new sections of it to tackle - both design-wise and self educating.  Some portions are easier than others; I was familiar with framing, so that was easy.  Insulation I'd done before (traditionally and on another tiny house) so that was easy.  

Metal roof design?  A greater learning curve but pretty manageable.  (I still keep waffling on color. Colonial Red?)

And the windows - that has been the biggest challenge to date.  Holy smokes who knew there was so much to learn?

Next came the front door.  Design, and hardware.  I've got those figured out for the most part.

And now I'm facing some portions that are more daunting to me: Plumbing and electrical.  Plumbing seems like the most difficult, specifically those pesky reservoir tanks.  Where do they go?  How large should they be?  How and why do you access them?  The actual running of pipes doesn't seem scary.  And then there is the water pump, and the filters, and the tankless water heater... those?  A wee bit more challenging.

But before I get to plumbing, I must address bathroom design.  The toilet I've mostly figured out; I wrote about the various options here and I've decided to go with the bucket and sawdust as written about in the Humanure Handbook.  I may or may not add a Separett Privy Kit  to the set up later. So that leaves a sink, some bathroom storage and the actual shower design.

I started looking at the standard bathroom design for the Gifford, and the shower area is 24" x 24".  I'm not sure that I can wash my hair in that much space without hitting my elbows on the walls, and I'm positive that I'd have to be a contortionist to shave my legs in that space!  To remedy that I've decided to make my bath a wet bath - you know, like on boats, where the whole room becomes the shower.  I'll need to figure out a way to cover the toilet and storage, and I'll have a curtain that pulls over the window to protect it from water.  The door may or may not be waterproof - depends what it is made out of.

Japanese Ofuro Tub (the more I look the less crazy it seems...)

I've started researching what materials I could use for the floors.  I like the look of galvanized metal, and I found one couple that built their own.  They wrote a step by step instruction of how they did it, and you can read that here.  I am less excited about having metal on the floor in the shower - doesn't it seem like it would be freezing on your feet in the winter?  But I could put down my teak bath mat and that would solve that issue.  And I do have a couple of friends who do commercial metal working, so I think a design could be within reach.

Then with a few Google searches I found some commercial options that aren't metal - they look like they are rubber (I've always suggested I may need to be in a rubber room... here is my chance, lol.)  Here is one: Altro Floors.  They do floors and walls, and it looks like they come in a variety of colors.  Hmmm

And here is another idea: DIY Wetroom.  This kit gives you the option of a tile floor (won't work for me - the tiles will probably crack as I travel) or a vinyl floor, both of which can get wet.

I haven't researched those in detail yet, but pretty soon I'll be digging into the details.  I have a feeling I am going to be in a RV supply store before it's all over.  Or maybe a nautical supply - that sounds more fun.
