How To Connect Garden Hose To Bath Tub Faucet

I'm trying to find an adapter for either my sink faucet or my tub so I can connect a garden hose to one of them. I have a large 7'x18' shower/tub "wet room" and would like to be able to use hot water to hose the wet room down while cleaning it.
The sink faucet is a Delta Victorian wide handle. The spout is 3/4" diameter has a male threaded end that is 3/4"-27 thread.

The tub faucet is a Delta Victorian Roman Tub wide handle. The spout has a male threaded end but the thread size is not documented anywhere. I even called Delta and they couldn't tell me the thread size. The spout is right at 1" diameter so I imagine it has a 1" thread of some sort.

Here are some of the adapters I have looked at.

Not sure if the 3/4" FNPT would fit the sink faucet, but this would be perfect if it fit......

With a 9/16" ID rubber fitting, I think I might could squeeze this over the 3/4" sink spout. Might be a tight fit though. Would be great if I could find one of these that would fit over the 1" tub spout. With this adapter I wouldn't have to worry about doping up the threads on the faucet.

Another option I am considering is to tap into the existing PVC and just put in a hose bib, maybe under the sink. I have seen several PVC hose bibs. This would be a little less convenient and quite a bit more expensive.

Any suggestions would be appreciated.

Most faucet aerators are not pipe threads, they're a straight thread with a gasket to seal them. I had a waterbed a long time ago, and it came with an adapter that fit many faucets to convert to a hose so you could fill the bed with it. You may need to stack adapters...find a straight thread that fits a faucet to a pipe thread, then the fitting you already found. Keep in mind, a typical vanity faucet is flow restricted, and your hose would not get a lot of volume and therefore spray pressure. Better to use the tub valve, which, in most instances, is not flow restricted.
Take the aerator off the lavatory faucet to a decent hardware store and they will have an adapter to hose thread that will work, almost certainly. You should even be able to set it up with a quick disconnect. Finding an adapter for the tub spout I doubt will happen.
As tom says take off the sink faucet aerator and take it with you to the hardware store. There will be a thread guide for you to screw your aerator onto, then you will know what size you have so you can get the right size aerator or in your case an adaptor for a hose.

You may need to stack two adapters to connect a hose.
