Installing a freestanding tub in a dog grooming salon

My wife is opening a grooming salon and we are trying to get it done as cheaply as possible. We are at the point where we need to install the freestanding bathtub. What I expected to be a simple task I am now not so certain of. As a nmatter of fact I can even figure out where to turn the water off at on this commercial space. I do expect to manage shutting off the water in short order but am not sure about the plumbing connections.

I was told this space was used as a small restaurant, and that the pipes coming out of the wall were a mixture of gas and water/drain pipes.

I am under the belief that what I am looking at is hot and cold water outlet with a 2" drain pipe directly under, I have this setup times two. If I am correct that this is a drain pipe is it reasonable to expect there must be a vent in the wall for this drain? Can I expect to be able to just attach to this drain without any issue? If I remove the caps from what I expect are water outlets can I expect them to be threaded or will it be bare copper pipe?

Please excuse my ignorance in this matter, I am appreciative of any insight anyone can provide. I will be sure to respond with updates!

Would have been nice if they had taped off the pipes before they sprayed texture and painted. I personally don't know of any gas pipes that come in hot and cold varieties. They usually are a stand alone pipe. Therefore, logic points to water supply and drain. The caps on the supplies are soldered not threaded.

I am curious why one "drain" is so much lower than the other. If you have access to the roof, you should see where the vent pipe(s) exit the roof. The relative location should be in close proximity to where these rough-ins are located. You can remove the cap and talk into the pipe and listen for the sound to come out the vent on the roof to verify connection. If you flush a toilet and hear noise in the drain pipe then you can verify connection to a sewer.

Gas would most likely be associated with or near a hood vent that would have been above the cooking area. If there is evidence of ceiling work that may help. I'm not a gas expert but usually end connections would be at a shut off valve and most likely iron pipe and not copper.

The reason the drains are at different heights is to match the drain connections that were on the removed equipment.
If you were going to solder onto those short stubs you would be advised to remove a small area of wallboard surrounding the pipes to make soldering easier and safer.

If this space was a restaurant you would do well to check to see if there is a grease trap installed in the building's drain and clean it if there is.

You also would do well to better seal the baseboard area near the sink as you will soon destroy the wall with spilled water and check the clearance of the receptacle as it may require a GFCI plug.
