Anybody built a Tiny House?

[etpm]

We converted my old office into a room for guests. This room is about 300 feet from our house so it will give any guests real privacy. The room is about 180 square feet. It is nice and we had our first guests stay in it for the last few days. They really liked it. The only drawback is no bathroom. Since the room is quite close to my shop guests can use my shop bathroom because there is a door to the outside from my shop bathroom. And even though the bathroom has a shower it is still a machine shop bathroom that has been used for twenty years.
Anyway, I want to add a bathroom. Since the room is quite close to a water supply and the septic tank it will be pretty easy to plumb the bathroom into the appropriate pipes. What I really need is some bathroom plans. I have been looking online and haven't really found plans. I have seen a couple but I was hoping there might be someone publishing a catalog of plans.
I am a retired machinist and though I can do a good job wiring and plumbing I know nothing about building. So some plans that are close enough to what I want that I can then modify if need be and show to a builder would be ideal. The amount of space that I have to work with is about 4 by 10 feet. This space restriction comes from the length of a wall and the proximity of the room to my shop.
I have seen pictures of bathrooms and read suggestions about designing a bathroom but what I would really like are some plans that I can manipulate some. I will be having someone build the bathroom because I don't know **** about building buildings and because of the fact that both of my wrists are bone on bone joints. But I do need to have plans of some sort to direct the people who end up building the bathroom.
Any help would be greatly appreciated.
Thanks,
Eric

Bathroom or washroom? Looking for just a sink and a toilet or trying to fit a shower or tub, too?

I designed our whole house with a home designer software. This is the company.

Our builder was able to just upload the file and make minor adjustments.

Shower, sink, toilet. I'm hoping to find some sample plans, I don't want to start from complete scratch. I really want plans that have been tested. I could draw up stuff with my Cad/Cam software but I don't want to. I need advice so that I can avoid mistakes that I would surely make. I am good at designing machine parts for novel situations and have more than once designed complete and complex products that are still sold today. But I need help for this.

Yes, we have and live in a 'tiny house' ....well, basically 2 of 'em put together like a doublewide. It's just under 600 sq ft.
Full eat-in kitchen, full laundry room, bedroom w/ walk in closet, living room, full bathroom.

The bathroom is 5' x 7' and is more than ample. Sink, full tub, real toilet (real plumbing to septic not a composter)

Tub across the 5' width, sink and toilet opposite 5' wall. Barn door in the middle.

I was trying to attach the drawing I have, if you want, I can retake a screenshot tomorrow.

That would be great. Thanks.

I'd like to know what a minimum use septic tank and field is required. As in 'Emergency Use' or maybe women coming here to buy hay or barn sale visitors who need privacy.
Bare minimu and with heat to prevent freezing in winter. I have water in the room I'd use, so what plumbing below the concrete floor?

Squeezed 3/4 bath in the upstairs off the master bedroom of a small 24x30 cape cod style cabin I built, used a smaller shower and small apt studio style sink/vanity used RV type nautilus brand retractable shower door, full size toilet. Very functional and it's our own bathroom when we have company. Unfortunately Pics, dimensions, and my drawings/plans are 500 miles away. I can say the retractable shower door and small vanity/ sink made it functional in such a limited space with a sloped ceiling and no dormers.

I've built several what might be considered "tiny" houses. Not sure of the exact definition of that. Anyway, 4x10 is plenty of room for a bathroom. I'd probably even be including a closet in that space. Unless the plans are just for your own satisfaction, you really don't need anything beyond a simple hand drawn diagram on a blank sheet of paper. I didn't even have that for most of the bathrooms I've built or remodeled. Usually it's just verbal. "Shower in this corner, toilet here, sink here" is about as complicated as it needs to be.

Standard sizes for depths of you have a 4' wide room is 30" for toilet and most big box store bathroom vanities have a depth of 20" or so shower sizes and styles are all over the place. If you go online you can find actual dimensions and make a plan. In my experiences building a tiny bathroom I used slightly smaller than the average sizes on sink, toilet, and shower. Me anyway, I'd make sure you know where the toilet is going for the mounting/ closet flange and shower which is a little more difficult to move your rough plumbing if you screw up and need to. Your going to need to vent shower, toilet, and sink also. Maybe consider hiring a plumber for roughing everything in if they'll work with you? If computers aren't your thing like for me you can get graph paper, a architects/ engineer rule and design template with all your bathrooms amenities to scale or that's what I did, and they are inexpensive.

Here is our 5' wide x 8' deep bathroom. The doorway is 28". Distance from vanity to wall is 36". Distance from toliet to wall is 30".

Working with a 4' wide space would make it tighter. Is there any way to stretch it to 5'?

 

[MattB4]

Really tight on width using just 4 ft (internal dimensions or ?). A shower stall on one end and a toilet on the other would be possible. In between on the back wall could be your sink/vanity. Not the best plumbing layout but sometimes you have to work with what you got.

 

[jjeff]

Wonder if the op would compromise on a toilet under 30" depth? I think that will stick out the farthest in that 4' wide room and you can run all the vent, and supply lines in one wall.

 

[Oaktree]

Have you checked local building codes? There may be specific requirements you'll need to follow.

300' is quite a run to use your house system (or city sewer tap) and septic systems can be expensive to install.

^good assessment. Standing in our 5x8, I wouldn't want it any narrower if it could be avoided.

Don't they go with a 5' width cuz most bath tubs are 5' long? Op said it's a guest bathroom in a converted office bedroom off main house don't want to make it to comfortable or guests may not leave lol. I think op wants functionality but not looking like it was backwoods cobbled together? From my experiences having everything on one wall makes it a lot easier to do a diy job. There are so many space saving but very functional things out there if you search the googler. Id also look into getting a exhaust fan if you don't have a window, might be code anyway. I ran mine in the wall out the gable end. Cuz I'm not the best at flashing metal roofs

 

[2manyrocks]

'5 tubs have a lot to do with it, but also you need some room in front of the vanity just to be comfortable.

Roofers just rely on silicone sealer and those silicone boots to seal vent pipes on metal roofs which IMO creates a maintenance problem later. I'd vent through the wall, too.

I built this bathroom for a client's pool house room. They wanted it as small as possible, but also to be functional for family to use when they stayed for a few days. They have a Murphy Bed on one of the walls, a TV on another wall, and a sofa in the middle of the room. We spent a year going over ideas on how to make it as small as possible, but also make it big enough to be usable and nice enough to make people happy that used it.

In the end, the final dimensions where 5x9 with a 32 inch door. ADA was a consideration because some of the people using it will be elderly. Zero lip shower so there wasn't anything to trip over. 36 inch vanity so there was some counter space. A pedestal sink would of taken up less room and allowed me to make it smaller, but there was zero storage under it, and nowhere to put "stuff" on the sink. A toilet needs 30 inches of width, and standing room in front of it to be practical, which is 5 feet. If you go less, you really can't stand in front of it comfortably. But I also needed 5 feet of depth for the zero entry shower without having to put a door on it. The shower is 3 feet wide and 5 feet deep. The handles for the shower are just inside the wall with the shower head at the far end of the shower. Your body blocks all the water, so nothing comes out of the opening. I installed an electric, on demand water heater above it with an access door that also allows for some storage up there.

^Awesome.

Don't put towel racks or anything protruding directly behind vanity if your under 5' width. in my tiny bathroom I use hooks on wall. Yep both bathroom exhaust fans are thru the gable. On opposite ends of cabin. Both Vent stacks and chimney are thru the roof with silicone, and boots/, though with an overkill of snow stops 1st winter after I got my occupancy permit sounded like a freight train sliding down a ten pitch roof took out a vent stack at sheeting level lol .if I could do it over id reconfigure the main living area and some of the first floor and run the chimney out the gable also.
