Shop bathroom

[Reit38]

Im getting ready for my shop bathroom. This is how I planned on running the plumbing other then the vent off the sink to the stink pipe. The toilet and sink will be within a few feet of each other. Also is it a good idea to add a clean out on the exterior of the shed before a septic tank. The tank will be set within 10ft of the shed.

that will work, but you could wet vent the toilet thru the sink and save some fittings & pipe. I'll draw up a picture a bit later if no one else beats me to it

Here we're supposed to have 2 cleanouts just outside. One sweeps in, one out.

 

[The Cobbler]

post 3 has it. just upsize to 2" from the lavatory T and the toilet ( wet vent )

I highly recommend plumbing a urinal in as well. It's pretty damn easy to do and they're much less hassle to keep clean.

Tempting. I will have room. I plan on making the bathroom 5x9 to have storage on the top of it

Urinals are really great for younger folks. However, for us older gents that take 10 - 15 minutes to pee we just sit down and read a magazine. Stream; dribble; stream; dribble; repeat until done. Even the prescribed pills don't let us pee a half gallon in 20 seconds like we used to do.

That said one vent for both (or all three) fixtures is all that's needed. What you posted originally will work just fine. Make it easy on yourself and do whatever you want. There're 37 ways to skin a cat.

I plumbed a shower in mine also. Just had concrete guy slope floor to the drain. I figured I could iuse area for storage if i did not finish shower install plus it gave me a floor drain if needed. If you really want to think ahead plumb in a w/d hookup. Rough in plumbing is mighty cheap.

I'm in the process of building mine this weekend. Toilet, sink, urinal and full size walk in shower on the inside. Utility sink and washer and dryer on the outside of the bathroom wall. Good luck with what you have planned.

 

[thammel]

If you can do it, add a shower. I didn't and I regret that. After yard work or messy greasy car work, a garage shower would be so nice!! One thing I did was put a nice garage utility sink right outside the shop powder room. I use that a LOT!!

 

[Reit38]

Bear with me? Not good withball thebfsncy pictured but this is how im thinking i want to run everything. Toilet on the left. Straight out and 45 to septic tank. Stink pipe inside the wall to the attic. 1.5 San tee just above the 3in back to bathroom sink and another san tee? Past that to another sinking the outside of the bathroom. Sink drains inside the wall. Cleanout will be outside shed before tank

 

[rooster59]

Not a plumber. I think your horizontal toilet pipe should connect to the vertical stack with a sanitary tee, not a straight tee. How do you access the clean out at the base of the vertical stack? Putting a bi-directional clean out just outside like Sumboodie said above might be better.

I edited after your post. I forgot to add there will be atleast one clean out before the tank.. more the likely right on the outside of the shed sweeping back to shed. Tank will be approximately 6ft from shed

Sorry to hijack the thread, are you putting an exhaust fan in? My barn bathroom/boiler is 12’x8’ only a sink and toilet. And I’m debating not putting in an exhaust fan. I’m getting tired or drilling holes in my new barn steel haha!

My shop is stick built with steel siding……and a bathroom fan….no windows in the bathroom, so a fan is a must, in my opinion.

 

[nadogail]

When my toilet was installed in my workshop, it sat in a corner with two additional walls making a closet. In one long wall a Pocket Door was installed to allow privacy. One short wall is 6" short of the ceiling.

The City Inspector told me i needed either a Window or an Exhaust Fan. i pointed to the 6"X 40" gap in the wall separating the toilet room from the rest of the shop and asked if that could be considered a window without glass. He nodded his head and said "I'll give you that."

I had considered a shower, but don't really have enough room. And, after reading some posts here and elsewhere, I learned that the inspectors tend to be a little more critical when there is a shower, thinking it might be rentable as living space.

I was also told there needs to be a fan or a window. I have a window.

Seems totally duplicative to me... If there is a shower or tree available. I 95% pee outside. Because I can.

The double down is an "outdoor" shower with no "gray water" calculation for septic.

But divorce is expensive. Do what works!

Local septic rules can be a thing. They don't consider trees.

 

[drmarkr]

We live out on the edge of Town on 5 acres and IP outside all the time. But people that come here to the shop as visitors don't always want to go outside and pee. And I like the fact that it's easy for them to hit the toilet when it's a urinal.... Seeing as how I'm the one that cleans it.

How big is the bathroom? You can easily fit a sink, toilet, and shower in a 5x8.

I'd take a shower over a urinal, no question

Agreed, Showering in a Urinal would be difficult; Urinating in a Shower is easy.

I’d have to measure, but I think it’s about 4.5 x 7. Plenty of room to do what you need, not really any extra.

Can’t extend beyond the toilet, as it goes under the stairs, that’s where the compressor lives.

I was also told there needs to be a fan or a window. I have a window.

I have a can of Fabreeze. No window or fart fan needed.

I'm curious - what is that software that you've used for the drainage design? I was looking for something similar recently, and ended up drawing (with a pencil) the drainage isometrics for my permit.

[ddurrett896]

I did the exact same setup except:
- no vent off toilet
- 2" PCV above sink drain went to roof as a vent

 

[75gmck25]

How about putting a floor drain in the room and using Kerdi or another product to make the entire room a "wet" area. In many Asian countries they also use this format to make part of the room into a minimum-sized shower.

You just pull a curtain on ceiling tracks around the shower area (tiled walls in that area, shower head is directly above, and controls are on the wall), and take a shower in the room. It takes up zero space if you are not using it as a shower, but gives you the option to quickly go into shower mode and clean up/off at your garage. Just a thought.

My last shop bath had vanity, toilet, urinal, shower, and a fan!

Was awesome.

Hard part was remembering to bring out a change of clothes before starting work.

I'd just walk back to the house naked enough times to embarrass my wife into stocking clothes for me out there

When I did my shop bathroom, I was in the same situation, didn't want to make another hole in the exterior wall. What I did instead was use a grower exhaust fan with a carbon filter and vented it to the shop space. Works like a champ.

Now that I’m back home, I went out and measured it.
4.5’ x 5.5’.

No wonder there’s no room for a shower.

That would be tight. Would have to make it a wet room

Local septic rules can be a thing. They don't consider trees.

Things wither quite rapidly when you pee outside at twenty below in blizzard conditions, and going outside in a driving rainstorm doesn’t help shop productivity.

Showers would be nice, but start pushing things towards the definition of an ADU, which brings about additional code requirements.

So now I plan on running my drain line in the wall cavity. Im thinking if doing 2 layers of 2in foam board at r10 a piece then 3.5 insulation within will my packed down a bit due to having 6.5in posts. Any issues any one sees with this?
