“Ok Norma. In my bathroom, I had a towel bar hanging just below my window. Painters came to repair some humidity issues and repaint, and they took down the towel bar. I wanted to put it back up, obviously not in the same place. 
So I measured etc. and started drilling with a drill bit for plaster and BOOM… I hit metal. Now I didn’t want to go and put 
in the metal drill bit since there is a structural problem 
around the window. I figured if I start fiddling with metal, I may lose a 
window! So I tried a little further down, and although I didn’t hit metal there, I’m 
running up again something. So how do I do this without making my wall look like Swiss cheese???” – WYSK Reader Jen

NV: My dear Jen, I definitely want to help you avoid your bathroom wall becoming a hole-ly mess!

So let’s get right to it… how to install a towel bar! It’s best to go through a stud, at least on one side, for more secure mounting – it’s not necessary, but preferred. Finding a stud is usually easy. Your situation is a little special for a couple of reasons: (1) you’re mounting through a plaster wall and (2) placement is under a window.

lathFirst, some Plaster Wall 101. Typically, a wall is framed out with studs, 16″ apart (on center). Wooden lath is nailed to the studs, and then plaster is shmeared on to the studs in a few applications. The end result is a smooth finish.

On the opposite side of the lath, however, there are bulging plaster irregularities. So who cares how it looks inside the wall, right? Sure… except when you’re trying to use a common stud finder!

A stud finder works by testing density, so when you slide the finder over the part of a drywall wall with a stud behind it, ding ding ding, it knows you’re over a stud (where it’s more dense). On plaster walls, with all the various thicknesses, it can’t tell what’s what!

Here’s the other challenge for you… under a window, there are more “studs” framed in for support, called cripples. So the 16″ distance rule between studs doesn’t apply.

THE GOOD NEWS:

On plaster walls, you can use a metal scanner to locate studs! The wood lath will be nailed to the studs, and the scanner will pick up the metal nails. With studs located, you can screw through the plaster directly into the stud!

In the event you can’t locate the stud, or it just isn’t at the right placement for the towel bar hardware, you can use a toggle bolt. This fastener will require drilling a hole through the lath and plaster that’s large enough to accommodate the bolt – the drill bit size will be indicated on the toggle package. For more info on toggles, check out my “Anchors Aweigh! How To Put Anchors Into Walls” Fix-It Friday column.

Plaster Wall Drilling Tip: To avoid the plaster from crumbling out or cracking, apply masking tape on the wall over the drill point.

THE BAD NEWS:

Ok, so you’re hitting metal and not sure what else. Ugh! Because you say there was a humidity and structural issue with this window, I’m afraid they may have installed something beneath it, perhaps an oversized metal sill, and that may be jamming you up.

WHAT I WOULD DO:

I’d contact whoever did the window/wall repair and ask them exactly what’s behind the wall beneath that window now. Then I’d ask them what they suggest is the best method to reinstall the towel bar. (I’d also ask them why the devil they didn’t reinstall the towel bar they removed in the first place?! Arrrrrrr…)


Listen hon, I know you just want the damn towel bar up, who blames you, but sometimes a little thing like this can turn out to be a hole-ly pain in the ass-umed it would be easy – it’s just the nature of the home repair beast! That said, I’m confident that with this information, plus your smarts and determination, you’ll get a new towel bar up, one way or another!

Best of luck, Jen!

    I am putting together a LP gas fire pit table for the patio. The legs (metal) attached to the tabletop (metal) with hex screws. One of the screws will not tighten in its hole. It just keeps turning endlessly. I tried to back it out by unscrewing it but I cannot get it to back out either, again it just. turns and turns. Have I stripped it? How do I get the screw out to use a different screw.

    Frustrated in SoCal,

    Sue

      HI Susan! Sounds like the screw is the wrong screw size (or hole size from the factory), or one of the two have bad threads.To back the screw out, wedge a flat tip screw driver behind the head of the screw as you’re unscrewing. Give it pressure, forcing in the outward direction while you’re unscrewing it out. You’re basically assisting it out with the pressure of the flat tip behind the screw head. Does that make sense? Good luck!
