I am going to drop in a new high efficiency toilet, because the existing one is big, old and leaky. Running into an issue with the rigid supply line -- I don’t know what is the best way to handle replacing it. I want to install an angle stop and a braided line, without damaging the wall too much or coming up through the floor/tile.

Here’s what I’m looking at:

What I'm thinking:
1. I'm able to chip away a little bit of wall paneling, get the rigid fitting off the wall, and replace with a compression fitting. Although, I'm worried I won't have enough purchase on the stub coming from the wall for the compression fitting to work.

2. Cut the rigid line and stick a compression fitting onto that -- then figure out away to add an angle stop so I can use a braided supply line.

Thoughts? Advice?

Thanks!
 
Should open the wall up and see exactly what you're dealing with and go from there.

Shut off your main and Use a 3/8 x 3/8” comp valve on the rigid line if you don’t want to open the wall
 
Use a multi-tool, cut a workable area vertically on the lines of the bead board, make another cut high up and the assess.

Looks like a poor job as they just slapped the bead board right over the valve.
 
I am a sorry excuse for a plumber; however, although now retired, I have handled literally thousands of property damage claims from water losses due to leaking pipes since '69, as an insurance adjuster. I would guess that the ratio of serious water leaks as a result of burst (there is a rubber hose encased in the stainless steel braid) flexible lines vs hard lines is probably around 50:1 or maybe even higher. People install flex lines because it is easier, but then they forget about them and eventually they leak (every time the toilet is flushed, the pressure causes imperceptible vibration and eventually the rubber hose gets worn and chafed at the bend in the line, and a weak spot is formed, and they burst) and if the leak occurs while you are away on a month long vacation, you return home to a flooded house with huge damages and MOLD. I humbly suggest that you stay with rigid, vs flexible, water lines; they last forever. Just a thought you may want to consider.
