I'm putting a piece of 2x4 on the wall and haveing trouble. I've used sqrew in anchors, and tougles, but still haveing trouble. Part of the problem is that it's an old apartment, and it's contained by the washroom so the drywall is brittle.

How matured is the washroom in years and are you the original owner? Some elder places have sheet rock over slat boards which can make it difficult to find 2x4s. Also some elder houses have boards spaced 14, and 16" apart due to pipes. Screw into the studs when you find them.

try finding a stud and screwing the 2x4 into the studs. they should be spaced every 16 inches

Possible cost of replacing kitchen ceiling?
if there's baseboard in the room, check to see if you can see nail in the board in a 16 inch or two foot cut-out. Thats one way to find a stud pattern. If not, guess 16 and 24 inches from both corners and make tiny pencil marks almost 4 feet off the floor and try driving a extraordinarily small nail at the marks to see if you find a stud. Good luck.

Go to your local lowes or home depot and go and get some anchors made by Cobra called walldrillers. They work great in frail or new drywall and plaster. Depending on what you are hanging is what size anchor to buy. In plaster, if the hole call for a 1/4 predrilled hole use a 5/16 bit for little larger hole so you do not destroy the anchor.

Answers:    don't you think you should buy it dinner first??
you need to drill into the studs. don't use dry wall anchors and screw with something heavy approaching a 2 x 4. get some long woods screws. 4" should be fine. next get a stud finder you can pick them up for around $10 at almost any retail/hardware store. follow the instructions, find the stud and drill through the 2 x 4 and into the stud.
