Small Houseboat Bathrooms - need head space for toilets on house boats?

Houseboat Bathrooms - so small and tiny.

Houseboat Bathrooms - so small and tiny.

When it comes to small houseboat bathrooms, we really need more space for a head, or a toilet on house boats. I am thinking of knocking out a wall and transform it to a larger bigger bathroom. I'm looking for any construction tips or ideas?

I am 2nd year owner of a 1984 Crest houseboat and love the boat. My only disappointment is the bathroom is so tiny and small. I have a storage closet that has a common wall with the bathroom, and thought about removing the wall to enlarge it.

I was wondering if there are any other Crest owners that have attempted this, or if anybody has any ideas to get a man's sized bathroom.

Thank you all, Tim, Des Moines, Iowa

Well Tim, welcome to the houseboat forums, and sorry to hear, and see your small bathroom. I see the size, and hope you're not a big guy...

I have often wondered if the houseboat manufacturers of smaller sized boats, actually hire engineers and designers, that during the prototype stages leave their desks, and take the time to really "test" their bathrooms. If they do, they must pee standing up :)

I remember on one houseboat that had such a tiny bathroom, my left shoulder would be squished against the wall, and my right foot had to be "in" the bathtub. Good thing my wife never took a photo of that.

But joking aside Tim, you should definitely take the time to investigate the layout and design. You could easily change the space and size, especially since you say that the storage closet is on the other side. You should first have a look to see if the closet wall is a structural support wall for the ceiling and roof.

Lastly, hopefully some of our readers will share and post comments about their construction tips, enlarging houseboat bathroom experiences. Feel free to use the "Click here to post comments." link found near the bottom of this page.

Thanks again for sharing, IAN from all-about-houseboats

Question about bathroom?
by: Anonymous

I am renovating a 20' x 16' shed into a 'guest cottage' and am thinking about designing a bathroom with shower head like on boats that when the door is closed you can use the shower head in the room without the water leaving that room. Any suggestions about where I should look to get started??

Houseboat Bathroom Inserts - where to find fiberglass insert
by: Anonymous

My question is this, can anyone tell me where I can find a new fiberglass insert with the molded sink for the head for a 1980 Crest Houseboat.

Enlarging 1981 Crest Houseboat Bath
by: Doug in Virginia

I saw your question and have no idea when you wrote it but I have a 1981 Crest houseboat with the same bath and I am in the middle of tearing our the closet wall and making the whole space (a huge 5'x 3' compared to the original 3'x3').

One thing for sure is the Crest people put this thing together to stay - have spent almost 2 days tearing out the metal propane area (no longer use propane on the boat), the walls, and the fiberglass bath (built to withstand an atomic bomb, BTW).

Since my house boat is old, I have spent more time repairing rotting walls and floor pieces than rebuilding the bath at this point. I am about ready to put a new floor down and will wait for warm water as I am moving the toilet to the center of the space against the rear wall.

However, even torn up, the space feels much bigger and I am anticipating being very pleased I did all this work. Tear out definitely calls for reciprocating saw and respirator and lots of time and effort. I will write later if you are interested and maybe submit a before and after.

Dry composting toilets for houseboats

Dry composting toilets have come a long way, no flush water, no black water, and minimal space requirements. Grey water is all you have to deal with, much easier than all that sewage.

Ideas for a Bathroom Remodel.
by: Anonymous

Plans for our remodel include installation of a shallow vanity with closed storage below and our second bathroom is being converted into a food storage pantry with stacking washer and dryer. As future liveaboards with 2 growing boys, both are necessities.

A word of Caution.
by: Old Houseboater

A too small bathroom or head is certainly a PITA (pain in the a**). However a couple of comments before you start.

1. you are going to sell the boat someday. Prospective buyers tend to like a boat with the stock factory look. If you enlarge the head can you do it so that it will look factory?

2. Your boat doesn't have that much cabinet storage, can you afford to give up any? Can you use half the storage width?

3. You have lived with it for 2 years. How much longer before you move up?

With all that being said, I spent $1500 in materials to put a tub in my KingsCraft because I don't like showers.

Let us know what you did, and be sure to send us before and after pictures. GO FOR IT

It's a great and inexpensive addition to any bathroom, and it also makes it much easier to clean is the Bathroom Bidet Sprayer (

You can shower, clean yourself, the toilet, the tile, even diapers if you have any. This is a must have for any modern bathroom, and it helps the environment by cutting down the use of toilet paper.
