Need Help

I have a seperate spa tub next to me stall shower. This tub was already here when I bought the home and have no idea what the make is. The spa tub has 3 seperate pieces on one side. The 2 handles and the water spout. I need to remove the water spout. There was a small button the the back I popped off and it looks like a tire vavle stem inside. I do not see any screws or nuts anywhere. What do I do?

Tub spouts generally are one of two types: those that push on and are locked with a set screw, those that are screwed onto a fitting. If what you can see can be turned with a wrench, screwdriver, or socket, it is probably a push-on variety.

spout

That is not a valves stem, it is an Allen screw that needs an Allen wrench to remove it.
