Screwing into shower wall?

I'm in the VHB school vs screws. I installed led strips under the coach 6 years ago with VHB. 50+K miles all around the country and still inplace. Get VHB rated for the weight you are considering and you'll be good.

The brackets that hold a shower head on the wall are screwed in place with an ordinary screw. So the walls are obviously thick enough to hold a screw.

Not sure I'd want to add a screw into a shower wall, but if you plan on the holder being there "forever" it should work. You could always add a dab of epoxy to the threads for extra holding power.

The bracket for our shower head was coming loose. I found that whoever put the screw in over-tightened it and stripped out the hole in the fiberglass. I simply drilled a new hole next to the original one and carefully tightened the screw back in. Gets very little water spray up that high and wasn't worried about using anything to help seal the penetration.

Another vote for the 3M command strips.

I mounted a couple of things in my shower. I just drilled small pilot holes and screwed the things to the wall. I "felt" the screws actually go into something solid (no, it wasn't wire or pipe either, lol) behind the plastic surround.

So, what is the difference between a screw that is siliconed vs. the plastic plugs they use at the factory that have no sealant on them at all?

I agree, less holes is better but for the record, I mounted a holder in mine with screws. I siliconed the hole and the screws to make sure its sealed. It also up high out of the spray zone. I also took out all of the factory plastic plugs, siliconed the holes and plugs before putting them back in. I don't see how those don't let water in.

Lol, LeClair!

Agree, use tape, velcro, suction cups. Leave the drill out of the equation.

I wouldn't screw into the shower housing. There is a reason this isn't done at the factory. It's very thin and provided you got into a stud, the flexible nature of the shower and the constant movement while travelling and expansion and contraction due to weather, it's bound to end up with a crack and/or a leak. And unfortunately, you'd probably never know when it starts to leak as it would be behind the wall.

Well, if nothing else, the thread title certainly set my mind wandering.

Cheers!

My soap holder is indeed attached with Scotch VHB tape, and remains in place after two years; also, the solar panels on my roof. Surface prep is important - be sure to eliminate any grease/oil.

I recommend double sided tape as well. Screwing into something in any RV is asking for trouble. Walls aren't that thick 1.5" maybe and internal framing is hit and miss.
