Need ideas on fastening to interior walls

[Bozo]

I used a magnetic catch on my glass doors. I think somebody else on here pointed them out to me.

So, has any found an answer on where to fasten the hand towel and TP holders and using what? My wife wants me to mount these items ASAP on our new 340RL. The TP holder seems easy enough to mount on the plywood trim in the bath. But where do I hand the towel holder? The walls look and sound awfully thin and I'm afraid that anything that I mount could easily be ripped out.

I have a Delta 252RL, and I used command hooks for both. Hand towel on the wall, and toilet paper on the inside door of the bathroom sink cabinet, easily reached when sitting in the prime pooping position

For items not needing anchors like photos, I believe a lot of people recommend museum tape or museum putty. Doesn't leave marks and is tough.
