Hi, the depth to the wall is about half an inch. About 2 1/2 to the roller. It doesn't hold mega rolls but it looks beautiful. I took a picture, hopefully that helps you out.
The ARISTA Recessed Toilet Paper Holder has a depth of 1.97" inside wall with a total depth of 3.6" from roller to back plate.
It is made of plastic, have had for over a year with no problems.
yes- I have a mega roll in their now.
3 1/2 by 3 1/2....inches
I installed mine a couple years ago, so I can't give a measurement. What I did find was it to be same depth as the one it replaced and the overall opening needed to be cut larger. Good quality and holding up well. If it's too deep for your wall, you could shim it out with a handmade custom frame to seat it on. That might look cool. It's also returnable. Good luck.
The closest we have to a brushed nickel finish is the Satin Nickel finish found here https://www.homedepot.com/p/ARISTA-Recessed-Toilet-Paper-Holder-with-Mounting-Plate-in-Satin-Nickel-RTPH-P-SN/205155858
From the cabinet side to outer edge of roller holder is 1 3/4".
