Plumbing – Trying to replace a toilet’s water supply line

plumbingtoilet

I'm investigating replacing my toilet's water supply line/the possibility of installing a bidet.

This is what my current supply line looks like

From what I can tell, there's no easy way to replace this type of hose without replacing the water shut off line, but I'm a bit scared to attempt that as I have no idea how difficult it is, nor do I particularly want to do it if I don't need to.

Is there a way to replace this style supply line easily, or am I going to need to replace the line + the shutoff valve?

As was mentioned, the gray hose is connected with a compression fitting at the bottom, and maybe a pre-crimped fitting at the top. In any case, they thread right off.

I'd go buy a stainless mesh-wrapped hose in the next length up from what you need and with the correct end fittings (standard for a toilet). These will have integrated seals, so just snug them up slightly.

Put a slight corkscrew twist in it to take up the slack. It'll look great.

Optionally replace the valve with a nice clean new one and shorten the supply pipe to get it closer to the wall. This will require a compression fitting, but they're not difficult if you start with a clean pipe. Be sure to use two wrenches, one on the valve body and one on the connection nut, so as not to strain the pipe.
