I had to cut a hole in my bathroom wall to repair a leak. Now I have to repair this hole I cut in my wall. The hole I cut was 21" x 27". The problem is, to get to the stud I have to cut out 7 more inches and that will take me behind a pedestal sink and I don't want to do that. My question is, do I have to cut over to the next stud to do a proper repair? I have a stud running up one side and across the bottom but that's it. Any ideas or suggestions?

If you have the room you can take a piece of 1x4 and use that as a floating stud.

Liquid nail half of the 1by and slip in behind wall, lay it flat against the inside wall so half is still showing and half is not. Screw it tight to old drywall. Let it set. Now you have a nailer to screw new section of drywall patch in.

txmnt - #1 - you can do it without cutting out any more sheetrock, get you four pcs of 2x4s and cut two sides longer then the other two , screw them around the hole you already have cut out < holding them tight against the sheetrock while screwing them to the sheetrock that is still on the wall< ::#2- now cut you a pcs of sheetrock to fit as tight as you can for the hole :: screw that pcs to the wall{ the 2x4s } put in enough screwse p #3- now mudand tape the wall at least three times<sanding between each layer of mud, smooth msake the next coat wider then the last and as smooth as you can
#4_ prime the wall and the second coat will be the ciolor you want note -you may<more then likely have to paint the whole wall use reg sheetrock mud to mud with < if you use dap you will be able to see every spot you mudded
i hope this has helped you with your problem <if i have helped you please rate my answer using the rate orange box below ;; let mud dry good between each coat ::good luck and have a better day tomorrow :: f.b.e.

I agree with boat. A floating stud will work fine.

Good luck

Works fine in all our plaster to drywall patching in re hap. Too many years of ripping out plater walls to get to plumbing and the carpentry end of doing remodel in floors of old buildings. Just needs a stiff nailer its not a floor.

You can screw a piece of wood to the existing sheetrock and screw the new or old piece of rock in the hole
