Hi everyone,

I'm trying to disassemble my shower column to replace/install a new hand shower rail wall mount, but I'm completely stuck trying to separate the bottom wall-mounting bracket from the vertical riser pipe.

The Setup:

• Unbranded / generic dual-head rigid riser shower system mounted on bathroom tile.

The Issue & What I've Tried:

• The outer chrome collar/sleeve is completely seized onto the internal core/wall anchor (the solid piece inside the pipe opening).
• I have already inspected the outside collar for hidden set/grub screws (none visible).
• I've attempted pulling, twisting, and leveraging it off using pliers wrapped in a cloth to protect the chrome, but it won't budge at all—it feels locked solid, likely due to internal limescale/mineral buildup or a tight friction fit.

My Question: Has anyone dealt with this specific type of generic riser bracket? Is there a hidden locking mechanism inside this inner core that releases the pipe, or does it strictly require descaling/forcing the sleeve off to reach the wall screw underneath?

Any advice on how to free this without damaging the surrounding tiles would be greatly appreciated!
