Well now, if you’re lookin’ to get one of them U-shaped drawer boxes made, you gotta know a thing or two about the size and dimensions, ’cause it’s not as simple as just cuttin’ out a hole. You need to figure out exactly how big to make that cut-out for the plumbing, or else you’re gonna end up with a drawer that don’t fit under the sink proper. So, let me walk ya through it, in my own way, so you don’t make no mistakes.

First off, the size of that U-shape is gonna depend a lot on the kind of pipes you got under your sink. Now, most folks’ kitchens and bathrooms have standard plumbing, but if you got something a bit more outta the ordinary, you might have to tweak the dimensions a little. Generally, you want that drawer cut-out to be big enough to accommodate whatever pipes are in the way, but not so big that you lose too much of the drawer space. You want to be able to pull the drawer in and out without hittin’ no pipes or causing trouble.
How big should the cut-out be?
Well, I’d say a good rule of thumb is to start with a cut-out about 6 to 8 inches wide for the pipe. But remember, you need to take into account the height of the sink plumbing too. Sometimes them pipes can sit real low or go up high, depending on how everything is installed. So, the height of your U-shaped notch should be enough to clear the pipes, but not too big, or you’re wastin’ space. A lot of people go with about 8 to 12 inches in height, but this can change based on your sink setup.
What else do you need to think about?
- Make sure there’s enough room for the plumbing to sit comfortably inside that U-shaped cut without crampin’ it too much.
- If you’ve got any special plumbing, like garbage disposals or water filters, make sure you account for that in your measurements too.
- And don’t forget about the width of the drawer itself. If you make your cut-out too wide, your drawer’s gonna be flimsy and might not slide right.
When you’re makin’ these cuts, it’s always a good idea to measure twice, and cut once. You don’t wanna end up with a drawer that don’t fit, or worse, one that looks all outta place. And if you can, get yourself some templates or guides to help line things up. That’ll save ya a lot of headaches, trust me!

What’s the best way to install the U-shaped drawer?
Once you got your dimensions all figured out, you’re gonna wanna make sure that drawer box is installed sturdy. You don’t want it wobblin’ around or droppin’ down after you put it in. You gotta secure it to the sides of the cabinet or the structure that’s holdin’ your sink, and make sure it stays level, so it opens and shuts nice and easy. If you’re doin’ custom work, you might need to tweak the frame a little to get it to fit just right.
Now, I know some folks get all fancy with their custom measurements, and that’s fine if you got the skills and the tools. But if you’re tryin’ to make things a little more standard, you can go with more regular sizes for the U-shaped cut-outs, so you don’t have to do as much messin’ around every time you build a drawer. It can save you a lot of time in the long run.
Do I need any special tools for this?
If you’re makin’ the cuts yourself, you’ll need a good saw, maybe a jigsaw or a circular saw to get that U-shape nice and clean. A drill for the pilot holes helps too, especially if you’re workin’ with a hard material like plywood or MDF. And don’t forget your measuring tape! Measure that hole out properly before you start cuttin’ or you might end up makin’ a mess of things.

Final thoughts:
Well, that’s about all I can tell ya on makin’ a U-shaped drawer box for plumbing. It’s all about gettin’ the right measurements, and not makin’ your cut-outs too big or too small. Once you got the right size for your sink plumbing, just make sure you’re installin’ that drawer nice and sturdy, and you should be good to go. And like I said, always measure twice, cut once! That’s the best way to avoid mistakes and make sure your drawer fits like a glove. Good luck, and happy buildin’!
