Looking to add a bathroom before winter. Have had a porta john for a week and it has been a godsend. Want real bathroom before winter. Freestanding building will need a small septic. Water is nearby to bring in the building, dig up near the yard hydrant to find it.

Want toilet, sink, shower, and additional sink outside it. Plan to frame up a room along 1 exterior wall or possibly in the corner. Square or rectangle and how to lay it out? Building got full quick so want to keep it small but not too small.

Will also run water a few other places for hose hookups.

This is the standard.. 5 x about 7’ - 8’ depending on sink and shower width; you could get down to 6.5’ but feels crowded.IMG_2880.jpeg

My shop toilet room, just a closet with a toilet in it, has a Pocket Door, hand washing is done at a repurposed Kitchen Sink in the main room. The pocket door does not need floor space to swing.

Showers are done in the house, not the shop.

Nix shower, put sink across from toilet, rotate so door hits side of sink. Could do a "shower" by making the whole floor a drain pan and putting a shower head in the corner, but maybe think of it more as an emergency rinse if needed. Can hang a 5gal hot water tank in the corner ceiling. Rectangle better than square.

If you take the diagram to the left above, and move the door and sink to the center and the toilet to the left, that would be the layout I designed for my shop.

Inside dimensions are 47" by 88".

I say ditch the shower. It doesn’t seem to get used much. I did an outdoor shower (I’m in SoCal) and it rarely gets used much other than for the dog or a pool shower. I put a 3 bay stainless sink outside, near the shower. It gets used a lot.

As far as a septic tank I buried a Liberty sewage grinder pump tank setup and it pumps to the house septic tank 100 feet away through a 2” pvc pipe. I have been very satisfied with it.

Swing the door out, it saves some space

I have a corner shower in the garage bathroom - I use it as a floor sink / mop sink most of the time
and I do take showers in it occasionally

My vote is toilet and shower only in the WC and sink on the shop side of the wall and an outswing door.
That's how I did mine. That way the sink can be used as a shop sink.

The challenge OP will be the septic. It can be DIY with a barrel or two for the holding tank(s) and some perforated pipe. Plenty of "how to's" online.
Not sure about the legality of it though and may be dependent on your location.

But they do work just like a real septic.

How many of you saying to nix the shower have fire extinguishers in your shop? Are they used often? A shower in the shop is like a fire extinguisher - it is a safety feature that may not get used much but will be essential when you get a bad chemical on you and need to get it off quickly - without taking the time to go to a separate building and wade through areas you would prefer to not drip chemicals on.

Shower has a few reasons.

Available for use during future house bathroom remodel.
Available for relative that cannot get into the tub very well.
Available for me whenever I want it.

I would like to redo my main bathroom in the house. It was a small half bath in the corner of the open dining room/kitchen that was bumped out into the garage to add a shower before we bought the place. Inswing door with poor layout. The door from the house to the garage is right next to the bathroom wall so the door has to move to make the bathroom bigger. On the other side of the house to garage door on the garage side is actually the laundry room. So if the bathroom grows the laundry shrinks. Since this will not be a 1 day project the shop shower will be nice.

Quick house bathroom sketch not to exact scale. Plan is to make room for a bigger shower and be able to walk back out without your leg rubbing the toilet while the doorknob hits you in the side.

Relative with declining health. Did not think they would be here for last Christmas. Temporary option for them.


For me. I work in the shop late 2 nights a week usually and when I go to the hose the dogs get up and all excited if I do not get into bed quick enough. Between me taking a shower and them running back and forth from the bedroom to bathroom door the wife gets woken up and pissed off. Quick shower in the shop then straight to bed once walking in the house. no barking dogs and pissed off wife at 2 am. Also would be good to use before hopping in the pool on the weekends instead of going down to the house.

A car and RV guy found a self-contained unit that was use in a large RV. Built platform, secured unit to wall and pluming. Was done in a day!!

I made a single barrel tank setup for my previous shop and it was still performing well after 40 years. This time I went with the Liberty unit because I am in a more public area.

It’s your shop, do what you want.

So much easier to clean up in your shop and keep the noise down in the house.

Easier to put it in now than later.

Keep the shower. I would use the plan on the right with the door swinging against an unused wall.
Make the bath vanity or cabinet as large as possible to allow storage of cleaning supplies that are used in other places in the shop besides the bathroom

I went without the shower. Room is just a touch under 5x5. Main reason for no shower is that I had heard that if there is a shower, the inspector will look more critically at other stuff, thinking it might be a habitable area, possibly for renting out. Secondary reason (might actually be the primary one) is that I simply did not have any extra room to spare.

Here is looking in the door. Past the wall that is across from the door is the compressor closet, which is under the stairs.
On the wall above the toilet is the water heater. No need to be large, it only does two sinks, virtually never both at the same time.

On the other side of the right wall is the shop sink, so plumbing is easy, it's all in one wall.
Short counter top over my rag bins, and the small parts washer.
Also a cabinet scavenged from a hospital (no longer permitted, courtesy of HIPAA) and a whiteboard.
The door beyond the whiteboard opens to the compressor closet under the stairs.

Maybe mentioned above, but make sure room for wheelchair access.

will come in handy for walker, cane, after hip replacement, etc.

and studs for safety bars.

I have a full bath in my shop (exterior dimensions = 8' x 8'): toilet, sink, and shower.
I hadn't used the shower stall even once in the 5 years I've been fussing in my shop -- -- until the boiler died in my house and it took three days to source and install its replacement. THEN I was V-E-R-Y GLAD to have a shower in my shop.

On the other side of wall on which the bathroom sink is installed, I have a 2'x3' janitor's sink:

That looks nice !
I like the Yellow ! I’m a big fan of yellow - nice and bright, fun color

A couple of questions for you -
1-
Did you make the sink shelf/ drain board ?
Great idea and practical

2-
What Brand is that Red Toolbox ?
I’ve been looking for a set up like that for a parts / nut & bolt cabinet

You can't really tell from that photo, but there is more to that yellow stripe.
I sheathed all the walls with green metal sheets to protect the OSB from dings and water splatter; accented with yellow stripe.

Nope - I bought it on-line.
It was either through https://www.globalindustrial.com or Nexel Industries back in 2021.
I did a quick search of both sites but couldn't find a similar offering. Good luck in your search.
Closest I could find BUT 24" X 24" and no drain board

It is not a tool box but is a Map Cabinet I repurposed for hardware. It is also called a Flat File Cabinet.
Found it on Craig'sList. Also check MarketPlace.

I pulled all the drawers and hammered out dents and lubed the runners, wire brushed/sanded the cabinet, polished the drawer pulls and the label holders, and sprayed painted the whole thing RED.

Ten years ago, we completed a whole-house renovation. The wife was in-favor of a bathroom outside of the garage, still a part of the attached 2-car garage. The design placed a central hall from the kitchen to the garage. On one side is a 9 ft x 6 ft full bathroom w/shower. The Rinnai exterior water heater is just outside of the exterior door to the side of the house, so the demand is met immediately when you twist the sink hot handle, or the shower hot handle.

Opposite the bathroom is the laundry/pantry, which holds a lot of food, clothing, dishware, and other things, lots of cabinet space both on the floor and in an 'L' configuration, chest-high. The pantry is 71 in. X 90 in. Both the bathroom and the laundry/pantry are 106 in. high. I like the extra headroom. I'm not needing the extra height, but when we did the layout, that's what we had, using the existing building footprint.

I use the shower to get cleaned-up w/o tracking my dirty clothes through the house. I drop off the dirty clothes into a hamper. across the hall, or sometimes I'll just put them into a wash cycle immediately. When needed I have a 'really dirty clothes' hamper which pleases my wife, so her clothes don't get washed with my work clothes.

I keep thinking about what to hang on the walls, I have pictures of famous GP drivers of the 1960's, when I was going to Watkins Glen that I think would be good to display, also my race tickets to Watkins Glen, Sebring, the Montreal GP, Monaco, and the Indy Car race in Detroit. I also have a picture of a Ford GT racing, the same one you see in the movie Ford vs Ferrari. The picture was taken at Sebring, but not by me. Anyway, I have lots of other auto/motorcycle pictures I could hang-up too.

We have the full bathroom laid-out so you can enter the bathroom from the hall leading to the house, or from the hall to the attached garage, or from outside the house, on a path to the pool. It's convenient, it serves the pool usage, and my trips from the garage to get cleaned-up.

From the hall into the bathroom:

A linen closet to the right.

Above, the exterior door opens onto the path to the pool.

20260612_161457.jpg

Above, standing at the exterior door, facing the door to the hall, and beyond that across the hall is the laundry/pantry.

The sink and toilet:

20260612_161349.jpg

Last, the shower, which has an overhead 'rain forest' showerhead and the wall mount hand-held showerhead:

20260612_161512.jpg

I like the 'rainforest' wide showerhead after getting cleaned-up, it's very soothing. You can also see it in the mirror of the 3rd picture.

I also have a playing field and the scoring 'tombstone' glass from an old pinball machine which I always thought would be a good addition to the walls, but that has to get approval from SWMBO.

I'm in-favor of the idea of a near-by shower in the event of exposure to some caustic chemical. Also, there was the reminder about fire extinguishers, have two 5 lb. ABC where you can reach them in a hurry, 10 lb ABC is better, as you're likely going to extinguish an incipient fire with that much protection.
