Hi folks,

I'm new here and was hoping to get some help as I'm designing a wet bar that will be housed inside a former coat closet. Due to the fact that I'm repurposing a former closet, I don't have a ton of space so I have to design this carefully and need to make sure I'm not violating any electrical rules.

I have about 21" of width and 2' of depth. I plan to have a counter top with a small wet-bar sink. Below the counter I plan to have a under counter refrigerator/ice machine combo unit. I have enough room for the sink and S-trap due to my counter height, but would like to make sure there isn't any rule against having the refrigerator directly below the sink (instead of off-to-the-side).

Here is an image I found which is 'similar' to my project, except that this bar doesn't have a sink (or clearance). Can I have a fridge directly below the bar sink?

For the vent on the trap you may be able to use an air admittance valve. Most codes allow, check with AHJ

The base IPC code allows AAVs, the base UPC code does not, so that's the distinction, absent local amendment. I seem to recall AZ has different plumbing codes in different jurisdictions within the state. WA, CA, and OR all use the UPC.

Thanks everyone for the help. I’m glad the placement of the refrigerator is not a concern (with proper GFCI outlet).

Appreciate the correction on the P-trap. I’m looking to run the drain pipe through the wall (about 2 feet) to connect to the drain pipe for an existing bathroom sink. Is there any issues with simply connecting this wet bar drainpipe into the bathroom sink drain pipe under the bathroom vanity (post p-trap)?
 
Edit: If it’s only 2 feet maybe I can lose the p-trap on the wet bar sink and tie into the bathroom sink drainpipe above the p-trap.
 
Sounds like a good question for terrylove.com.

That said, every trap arm needs to be vented before (dry vent) or as (wet vent) it connects to another drain. The one exception is that the IPC allows common venting, where two trap arms join before hitting a single dry vent takeoff.

So you need to figure out the details of your existing configuration and which plumbing code you are under.

Cheers, Wayne

If there is a drain pipe already in the wall and it services a bathroom sink on the other side of the wall, then yes, you should be able to change that drain pipe in the wall to accept two trap arms (that's what they call the arm that comes out of the wall). That will also give you a P-trap on the wet bar side. Inside the wall, there is probably a single tee fitting and that gets changed to a double tee. Now, if the other side is a fancy bathroom with multiple sinks, for example, it may be more complicated.
 
All I'm going to say is you must have a very shallow sink or a pretty short fridge to make this work, or maybe route plumbing through the fridge:unsure:
 
Another consideration. If the two areas with sinks are sharing the trap, I would think the rim elevation of the sinks should be at same level. I have seen where an obstruction occurs in the drain trap and it will back up into the other sink, (two sink bath) but issue was immediately visible. But the suggested installations being in seperate rooms the only indication that a higher sink is not just draining slowly is maybe hearing the overflow or someone screaming about the overflow happening. Bathroom vanities are usually lower than the kitchen cabinet heights that would allow for mini-fridge to be install under cabinet. Also not sure of plumbing code and need for plumbing access space if the mini-fridge is under the sink. Only mini-fridge I've installed was a fixed unit that had secure-in straps similar to a dishwasher so it was "perminantly fixed in place" that would restrict access, not sure of other mfg.

I've seen rather small "dormitory refrigerators" but all the glass door "wine coolers" I ever seen usually are too tall to even consider a sink above them (for a 36" high counter top level anyway)

Haha. You’re right. The sink is a special shallow bar sink about 5” deep. The refrigerator is also more wide than tall. Was the only way to fit the sink, plumbing, and refrigerator.

Guessing you still maybe need to elbow the drain immediately and put trap in or at least close to the wall though instead of conventional trap directly below the sink.

This is the fridge which is only 28.5” tall. The counter will be 42” which gives me about a foot for the shallow sink and drain.

Thanks. I posted a picture of where I’d like to route the plumbing through the wall to tie in with the bathroom sink. The sinks are however at different heights. I guess I have some reading to do.
