Shop bathroom design input

[tmshort]

I have (had, I guess) a bathroom in my 24x36 when I bought the place 10+ years ago. It was a disaster, very poorly done, and I gutted it about 4-5 years ago with the intent of redoing it. Still a bare space.

It sits in one corner of the downstairs, and is roughly 80x73”. I am redoing everything, including cutting the floor to move the toilet flange. The guy who built the place set it too close to the wall, and the toilet that was in here had a cutout in the drywall for the tank to fit up against the studs. So, I can plumb in whatever is needed for sink / toilet / etc.

I’m interested in opinions on best design and for do’s / don’ts for a shop bathroom.

My goals:
- huge sink
- crapper
- urinal
- some sort of hot water, I am not sure on the best option for this. All electric, and I am detached ~75’ from the house.

Here are a couple drawings I have made trying to think this through. I have in mind a 72” wide double bowl stainless restaurant type sink, with work areas to the side of the bowls. I am not an artist / architect, so excuse the crude drawings:




”T” is toilet, “U” urinal. The door is currently in that location but could be moved anywhere along the left or bottom wall (the other 2 are exterior walls). I am already down to studs in there so moving the door is not a huge additional project.

Thanks in advance for your thoughts and advice.

This is an example of the type of sink I’m considering:

Regency 72" Two Compartment Commercial Sink with Stainless Steel Legs, Cross Bracing, and Two 18" Drainboards

Outfit your facility with a long-lasting sink with this Regency 72" two compartment commercial sink. It's constructed from high-quality, 16 gauge, type 304 stainless steel, making it more corrosion-resistant and durable than other sinks made from thinner, 18 gauge material. This sink features...

I didn't think about this until we were doing some remod plans ourself, but knowing what I do now, I'd do tile walls and (slip resistant) floors with a center drain, and a setup to have a shower of some kind (even one of those handheld sprayer thing)... Because if you have a battery "pop" all over you, or get hosed with some chemical stuff, it's awful nice to have a shower to hose yourself off, or to double as an eyewash. You may not hardly ever use it, but if you need it, you'll be kinda sorta glad.

Put a separate stop/waste valve to drain all those fixtures in winter. I don’t have a pocture of my sink…but one of those restaurant type faucets with the high neck and reach over sink works great for sinks like that.

Agreed. Also it prevents unnecessary tracking of shop dirt into the house, you can be pseudo clean before heading in. I'd give up the urinal for a shower in a heartbeat. You can always pee in the crapper.

I'm with the folks recommending a shower instead of a urinal. If I have to just take a leak, most of the time I'll step outside anyway...shoot, that's what I do even when I'm in my house!

 

[K'ledgeBldr]

When there is anyway to avoid putting plumbing on an exterior wall- you do it!

I'm betting there is nothing wrong with the rough-in of the toilet- it just had the “wrong” toilet! Standard offset from the wall for a toilet is 12” (13” from studs). But toilets come in different off-sets; 10”, 12”, and 14”. So, before you destroy a perfectly good rough-in, check the measurement- get the right toilet!

I suspect you are putting in the large sink so that you have good cleanup for the shop. I would think having to do large clean up of greasy, filthy, or just plain large stuff in the bathroom would be less enjoyable then in a larger shop space. If you agree, how about moving the double sink to the shop side of the wall and either eliminating or using a smaller hand washing sink in the bathroom?

Doing this might allow you to also keep all plumbing on inside walls as well as allow you to use common drains and stacks.

 

[mike93lx]

I would do a single, large tub sink, a shower stall, toilet (look for a smaller rough in, as noted above), and maybe even a hookup for a compact stacked washer and dryer.

The washer in my new house is on the second floor, after walking halfway across the house and a bunch of carpet. I hate carrying filthy stuff all the way up to it and miss having one in the basement

Water heater can be a compact 6-10 gal unit. Your showers wouldn't be long, but with a shower head that has a shutoff and is low flow, it would work well enough for a clean up

Or use the toilet. I can't see a need for a separate pisser in a 1 man deep garage.

We just had a pisser and ******* at work, would have been nice to have 2 shitters instead.

Agree that a urinal for a one-man shop is a waste. That space could go toward a shower or even a stackable washer and dryer, two things I would find way more useful in a shop.

I purchased a tool box from a guy many years ago who had an interesting shop bathroom.

It had a concrete floor and a central floor drain. The walls as I recall were concrete backer with just Red Guard or Dryvit or something rolled on. A shower head just came out of the wall so there was no tile and no separate shower stall. The entire room was just one big shower stall.

I don't recall if he had baseboard or anything at the junction with the floor.

The sink area was a piece of leftover granite from his kitchen held up with some beefy but decorative metal brackets. No wood cabinet to get wet.

This guy could have afforded whatever he wanted but came up with a really attractive but inexpensive way to have a shop bathroom with a shower. If I were building a shop it's what I would do.

My previous detached garage I built I had a bathroom with sink, toilet, urinal, and shower. Then a slop sink in the shop space.

IMO -- it's better to have a nice small bathroom that does what you want it to do and a separate sink for cleanup outside of the bathroom. Basic good fixtures are not expensive. You can also get a small electric wall heater -- to bump up the temp. Nicer all around.

How many people will use this ? I toyed with a urial at one time -- but, I did not have enough usage going on.

There are many ways to do a clean up sink and this depends on what you are doing .... I did not need or want double sink . Mine is a deep single with a metal grid on the bottom ... top mount on a long counter

 

[NUTTSGT]

I'd take a shower over a urinal any day in my shop bathroom, even a small corner shower.

If you're going with a SS restaurant style sink, check Govdeals for a decent used on. If you go with that style, definitely put a sprayer attachment on it along with the facet.

One of life's many pleasures is taking a leak in the great outdoors. Most of the time, I'll save my visits to the toilet for taking a dump.

 

[evildky]

Generally speaking it's most efficient to put all the plumbing on one wall. If you want to use the giant sink that's obviously out. The top option wiht the utinal placed between toilet and the sink may allow you to have all the plumbing in one wall. If not it just around the corner as opposed to the opposite wall.

 

[The Bean]

Considering that you will probably use the sink more often than the toilet, I would make that the closest fixture to the door...

Don't forget a fart fan and a timer

Love the shower in the garage. Really handy when you get really filthy working on stuff to keep the mess out of the house. Just keep a clean change of clothes there and you’re all set.

 

[Ak Jim]

Here’s a couple of pictures of my garage bathroom. I wanted a big single basin sink for washing large items. I used a kitchen faucet with a pull out sprayer along with a utility faucet that you can hook a hose up to. That way I can hook up the hose to wash a car and still wash my hands or fill up a bucket. In the shower I went with a set up with a handheld sprayer. That way it’s super easy to clean things in the tub. The tub is big enough to hold really large items. It’s also great for washing of waders etc after a fishing trip. The shower rod is thick wall stainless steel rod held in place with metal brackets. All of the screws for the bracket and wood all go into blocking I put in the wall prior to drywall. The shower rod is easily strong enough to hold clothes or waders while the dry.

I always thought that if I ever built a big enough shop that included a bathroom, i would build a bathroom that looked more like a upscale home bathroom. Tile, nice walk in shower, urinal, nice mirror and finishes... Why you would i do that? The ladies that visit would love it!

 

[hans109h]

Not sure what your outside situation is, but I'd consider a exterior door directly outside. It can be handy to get right into the bathroom especially if there is a shower.

 

[mopar4u]

Go simple and cheap

 

[finn]

Close clearance toilet, comfort height. Skip the urinal, small sink, but a slop sink in the shop, add a shower, install a fan.

 

[pennsylvaniaboy]

I would do a stand up showerr urinal, small sink and toilet inside the bathroom...put the large wash/utility sink on the wall in the garage....

 

[cvairwerks]

One thing to think about is going with foot pedal valves for the sink. Makes it less of a cleanup hassle if you have nasty hands or get them splashed with dangerous chemicals. Step on the valve and instant water.

 

[Jim_No_Garage]

Stall shower if possible.
Toilet.
Sink.
Mirror/Medicine cabinet.
Heat/AC ducting.
Fart fan.
Magazine rack.
Good lighting.


I agree with having the slop sink outside the bathroom - you'll be happier that you don't need to be in the WC any longer than necessary the morning after Beer and Burrito night at the local Mexican restaurant.
