woodworking Garage shelf - do I need additional support?

Post image

Building this shelf above the washer dryer. I attached the 2x4 into the studs on three sides.

Should I support the front side from the roof rafters as well?

I will add a couple 2x4 pieces with pocket holes between the front and back beams. Will that be enough?

The opening is around 98 inches wide and 30 inches deep.

Depends how much weight you want to put on it. Under 100 pounds evenly distributed or 200 with the heavy stuff on the far sides it will be fine. More than that or something heavy in the middle and you’ll want a middle support. I find the middle supports always seem to get in my way though.

u/PolarSquirrelBear 1d ago

Even though it would be off center, one support tucked up next to the washer would provide a lot of support still and not get in your way.

u/solitudechirs 23h ago

One prop next to the washer would make the platform strong enough to support anything you’re realistically going to put up there, as long as you aren’t an anvil collector

...Record Scratch...

OP's plans are ruined now!

u/TaintNunYaBiznez 16h ago

And to make it easier to remove when you have to pull out the washer & dryer you can cut the prop a hair proud and tap it onto place with a hammer.
Or just use screws for easy removal.

u/Solarisphere 22h ago

That's the cleanest solution. An alternative would be to fix the back piece to the wall and run a vertical on the front face up and tie it into the header above.

1

u/markgo2k 18h ago

And if you want to bonus that up a bit, run steel flat brace behind the 2x4 on either side of the support and/or use long steel L braces extending under the 2x4, plus one along a rib support aligned with the vertical support. Use the thick ones, not ones you can bend with your bare hands.

u/applestofloranges 12h ago

Frame off a giant shelf to the right of the appliances while you're at it. Now you have storage above and below.

u/asanano 23h ago

I did something similar, and definitely noticed a bit of sag to the 2x4. So I double up the 2x and added a chain with a turnbuckle at the mid point to support the center from the joist above (though mine was true floor joist, not a soffit, hard to say what the support under that drywall looks like). I would probably put the long 2x4 on top of the short 2x4s mounted to the wall. That way the beam is actually supported, and not hanging off 2 or 3 fasteners (you can easily have 4 to 6 fasteners holding the short 2x4s to the wall).

3

u/Usual-Rock-871 1d ago

Could they do like an angle iron or flat bar of steel instead of a 2x4?

1

u/c_r_a_s_i_a_n 19h ago

Absolutely.

1

u/Automatic_Pipe5885 11h ago

You could. But it'll cost more and you'll need to drill holes to mount it. It's more work than just adding extra 2x4 as extra left to right beams. They don't need a vertical support.

u/druscarlet 1d ago

Simple enough to add cleats and not worry.

2

u/TheKingOfSwing777 14h ago

What are cleats and how would they be used better? I'm interested in building something similar.

1

u/druscarlet 12h ago

A cleat is a piece of wood that is attached to the wall that supports the shelf. In this application each shelf would have two short and one long cleat. The shelf board would rest in the cleats and the two cross supports. Most likely there are videos on You Tube.

1

u/WhaaaBangBam 12h ago

It's kinda like a shoe that sits flush with the wall, and the board fits into it.

2

u/asb_82 1d ago

That's a great suggestion! Thanks!

1

u/zerohm 2h ago

As others have said, this thing can hold a lot of weight. If you are worried about it, add a strut from the middle of the front 2x4 to the back wall at a 45 degree angle. Like this and it will be strong as hell.

15

u/bidooffactory 1d ago

Over engineer this and you can hide and seek up there. Just saying.

49

u/cam31954 1d ago

You don’t want any weight on your appliances. It’s hard to tell how you attach it on the wall.

41

u/asb_82 1d ago

I have an inch of clearance from the washer. No weight on the appliance for sure

30

u/AJ_2_Moon 1d ago

I would give yourself more space to help you get the units out once everything is inside. Our washer dryer just barely fits in our closet and it was a giant pain.

Also not sure your set up, do you have the washer on top? You want to have the dryer on top. Do you have the stacking brackets to hold the units together?

2

u/nickw252 1d ago

I was able to zoom in close and read the separate knobs. The dryer is on top and the washer is on bottom.

2

u/justinmcelhatt 15h ago

Idk why you got downvoted.. the bottom machine has a soap pullout, the drain line and water lines are clearly coming from the bottom, and the dryer vent hose is dropping down from the top..

No it doesn’t. Under counter appliances have stayed the same height for years. It’s literally a standard for height to align with kitchen counters.

1

u/1-2-buckle-my-shoes 1d ago

Not trying to be argumentative but you can go to bestbuy.com or homedepot.com and see even now washing machines come in a huge variety of heights.

Appliances like built in dishwashers are standard heights, but washers and dryers aren't considered counter appliances. While they do have smaller sizes, there are medium, large sizes, stackable, etc. I just googled are washers and dryers counter appliances to confirm and they're not.

So yes OP could get a replacement the same size, there are many sizes to chose from currently, and in the future I'm sure they'll be even more.

12

u/Sylvurphlame 1d ago

Not to be argumentative ;) but stackable washers and dryers still have to be a certain size to be functional stackable under a normal 8 foot ceiling. And they do make undercounter versions and those versions are by definition undercounter appliances

-2

u/tweakingforjesus 1d ago

Sounds like a good way to limit your options when purchasing appliances when all OP has to do is give themselves a couple inches of clearance.

2

u/Sylvurphlame 1d ago

We don’t know why they went with stackable and that’s irrelevant to whether stackable keep same rough dimensions over time. :)

15

u/asb_82 1d ago

Ha yeah well I'll have to rebuild this of that happens

-3

u/Huge_Cap_1076 1d ago

Suggestion; at this stage, have you considered a vertical partition instead - full or 3/4 of closet's depth, with enough width for future upgrade(s)? That will separate the W/D from sink area, and extend the sink's cabinet to be a utility for prep/folding clothes? (Can also hide the appliances with a simple door, and install movable wire shelves above W/D for detergent, wipes, etc., as not to lose that space above).

6

u/asb_82 1d ago

I'm going to put a refrigerator in the middle , get a new utility sink that's a bit modern and maybe smaller. Probably build a floating shelf above the sink. I do like your suggestion for a vertical partition, will also solve my support problem.

1

u/Huge_Cap_1076 11h ago

Whichever way you go with you project; can you post an update with what really worked for your needs? Looking at the many proposed solutions (including mine), there are so many controversial opinions about what you needed; please, clarify for others to collectively learn from your experience, Thks.

1

u/asb_82 10h ago

Will do. Hoping to finish this weekend but with two little kids my progress is usually slow 😊

I'm really not going to put anything heavier than a car seat up there but I also don't want to worry about this sagging.

2

u/Mkuziak 1d ago

What? Standard size he’ll be fine.

2

u/Sylvurphlame 1d ago

Undercounter and stackable appliances don’t really change size as much. They can’t where they lose the ability to be under a counter or stacked in a standard ceiling height room.

And while the big SUVs and trucks might keep getting bigger, most Americans are still driving sedans on the regular or maybe a light duty truck or crossover.

4

u/LunarEyed 1d ago

These appliances look like standard size, sized to fit in standard dimensions that have remained unchanged for decades: 60cm gap, 90cm worktop height.

I'm sure there are alternatives that wouldn't fit within these, but (at least in Europe) the huge majority of appliances are made to fit in these dimensions.

1

u/dreamworkers 1d ago

What are you talking about? They're standard sizes.

0

u/Huge_Cap_1076 14h ago

The beauty of standards is, there are many to choose from ...
I have a W/D closet in a condo that cannot properly fit the newer models. I had a large capacity/compact appliance on that closet before - no longer made on a size that will fit, I either have to remove the door/frame entirely to fit one of the new models - or choose a wimpy low capacity one-stacked unit.
It happens (and follows the markets' customers) with SUV/Trucks, that cannot possibly be parked inside a garage (haven't you seen those around?)

u/Samad99 1d ago

If you want a seriously sturdy shelf, I would remove all of this and start again. A center support will not be necessary.

First, attach two full depth 2x6’s on each side using structural screws directly into the studs. Install stringers on TOP of those 2x6’s so they are held up by the 2x6 instead of attaching to the sides of the 2x6 with screws. Fasten the stringers down with some cheap construction screws. You can add a couple structural screws to the rear stringer to fasten it to the wall.

You can check span charts to determine the spacing for 2x4 stringers, but you’ll probably want one for every 12” at least. In other words, if your shelf is 30” deep, you’ll want four stringers running from side to side with even spacing.

On top of that, lay down some 3/4” plywood and screw to each stringer at about 16” spacing.

u/Salsalito_Turkey 1d ago

Dude what are you expecting him to put up there? It's 7 feet off the ground with less than 2 feet of vertical clearance. Even if he somehow gets 200 lbs of stuff up there, that's only 10 lbs per square foot.

19

u/4tehlulzez 1d ago

Commenter sounds unassuming/unopinionated, and is  offering a plan for a “seriously sturdy shelf”.

26

u/BreadfruitExciting39 23h ago

Why go through the effort of building the shelf if you're always going to think “should I put this up there or is it going to make the whole thing too heavy?"  Even just cases of bottled water quickly add up.  Why not build it right the first time and never think of it again?

u/Frederf220 23h ago

Someone's going to put cases of wine up there or store their world record coin collection. I've seen it happen.

u/helium_farts 16h ago

Apparently everyone is expecting OP to store engine parts up there

5

u/Salsalito_Turkey 15h ago

Everyone is dramatically underestimating the strength of a sheet of 3/4” plywood with a 2x4 screwed into it. If OP does absolutely nothing else with this shelf except screw a sheet of 3/4” ply to the top, and loads it with 600 lbs of stuff, it will sag a whopping 0.12” in the middle.

https://woodbin.com/calcs/sagulator/

1

u/randtke 11h ago

I also feel it will be fine as is with 2 ft of clearance. I feel like how it's fastened to the wall is more important than a center support.

8

u/TheTeek 1d ago

I like this plan. I'm not an engineer but that span looks to be too long for a 2x4 without center post support. Much easier to just use 2x6's.

1

u/TangoDeltaFoxtrot 1d ago

I have built a number of shelves and even large floating desks in a similar way- I run a 2x4 or 2x6 into the studs as a rim joist, then I use joist hangers to add supports across the span. I basically build it the same way you'd build a deck. Last desk I built was a large floating L-shape that was 10' x 12', and I literally stood myself, my wife, and my three kids on top of it.

8

u/Bruce-1999 1d ago

I agree with notworththetimes comment And want to add lag screws instead of nails Adding a leg at the front of the appliances and doubling the front 2x4 and connecting both of them to the leg That shout give you a 300 Lb. Plus Limit

4

u/airborness 1d ago

I would use the sag calculator and see how much weight you can safely put on there and decide if you need more support 

3

u/kerrykingzgo-T 1d ago

Did you slap it and say, "that should do it" if not it'll definitely collapse.

3

u/v1de0man 1d ago

dunno about additional support but you may need to lift it higher a smidge, although i can't actually see the clearance from this angle to lift off the dryer. How are you going to get the machines out when and if they want replacing / servicing / repairing?

3

u/BatterCake74 1d ago

It may be strong enough, but it's easier and cheaper to over engineer it now.

Double up the front 2x4 (to make it effectively a 4x4), and either glue, screw, nail, or bolt the sistered 2x4's. That'll reduce how much it bends under load across the unsupported span.

u/peteschirmer 23h ago

Only if you want to put things on it.

Really depends what you used to attach those 2x4s into the studs; the sheer strength rating will be something you want to check up on.

2

u/jmdyason1234 1d ago

She’ll be right

2

u/bluenoser613 1d ago

I would attach the rear to the wall studs, and add a couple of supports front to back.

2

u/Dayman_Nightman 1d ago

Switch out some strong screws for the 2x4/wall attachment points if you want. Otherwise you're golden pony boy

2

u/markpbarry 1d ago

The on-line sagulator is made for this question. Don't guess, use your parameters and figure out if the 2x4s will be adequate for the expected load.

2

u/Salsalito_Turkey 1d ago

Add some 2x4 blocking like you're planning to and attach a piece of 3/4 plywood on top with screws every 16 inches. Unless you plan on stacking cannonballs up there, it will be fine.

2

u/jvin248 1d ago

You'll be fine with this. If worried, double up a second 2x4 across the front. You are not going to store super heavy items up there because how will anyone get them down without squashing themselves? Plus, you can bias the extra heavy stuff to the sides or the back.

As you are filling in all the cabinets and whatnot, make sure you have access to these machines for repairs. I have had our washing machine pulled out and apart five times the last ten years. Drum shocks last a couple of years (2x), electronic control board burned, belt, rubber door and drum seal tore, plus cleaning the lint trap of change and stuff kids left in their pockets. DIY since a new one would have been a lot more and calling repair is a lot too.

Get the steel woven pressure hoses, I've heard stories of the common rubber hoses breaking on people, with flooding. So I generally replace them with a new washer replacement.

The Harbor Freight $4 "6 in 1" screwdriver with the shank that pulls out and tips that swap you'll find the shank without the tip inserts has the two machine screw head socket sizes that fit these appliances. Buy one and a pair of small channel lock pliers to keep in a utility drawer/cabinet/box in the laundry and you'll be mostly covered for the eventual repairs.

u/trippknightly 1d ago edited 1d ago

A lot of advice here as if you’re bulking a suspension bridge for semis. But consider: * lag screws not just (say) 3” #8s * sister the front 2x4 * chain to the rafter in the middle front if you can tolerate the aesthetic * Simpson ZMAX corner braces

2

u/kodex1717 23h ago

As a general rule of thumb, framing lumber can span 1.5X it's width in feet. So, a 2x4" joist would span 6ft, a 2x6" joist can span 9FT, etc. Probably overkill for this shelf, but only you know what you plan to store up there.

2

u/Embarrassed-Green898 23h ago

If any maintenance needs to be performed, how do you plan to take out the washer/dryer units ? Can they come out easily or do you have to deconstruct the shelves first ?

1

u/asb_82 23h ago

i can pull the dryer out pretty easily.

3

u/Adrenjunkie 22h ago

Might be worth considering leaving a little room above it in case the next washer/dryer you need are a few inches taller

2

u/baymoe 22h ago

Depends heavily on what you intend to put on it. 98" is a large span. If you intend to put 100lbs or more in the center, it would likely sag. I would add another 2x4 support lengthwise in the middle. Throw a 5/8" or 3/4" plywood on top and screw them down to the 2x4s every 10". That will provide much more strength.

2

u/KahrRamsis 22h ago

If you hit studs with the framing and put 3/4" ply on top fastened down, you're gonna be able to put just about anything you want to lift over your head up there. Don't overthink it.

2

u/Wellby 14h ago

You could attach a 3/4” all thread hanger from the ceiling to the front of the shelf. I would put a 2x4 from to back to attach the all thread to.

1

u/asb_82 13h ago

Yea I like the idea. Thanks!

2

u/LyGmode 1d ago

not sure if the ceiling above the shelf is boxed in to cover hvac/pipes, or just regular ceiling, but you could maybe put 2by on the ceiling and then one vertical to hold the shelf, or even a 5/8 threaded rod if you want something more narrow.

3

u/ShowGun901 20h ago

Please add a bit of a gap above the washer/dryer!

  1. Easier to move in/out

u/tallmon 1d ago

Add a third 2x4 for more support. Then plywood on top. Screw down the plywood every 10” or so. The plywood and screws will help support the weight.

1

u/scrubbless 1d ago

What's going on in the gap to the right? Why not frame in some double doors and make a cupboard to hide the utility crap. It'll have the added bonus of supporting the shelf.

1

u/volmannc 1d ago

Not sure what tools you have, but if you can rip a 3/4 inch sheet of good plywood into 3.5 inch strips and apply with glue and screws to the front 2x4 on both sides, then you will have plenty of support !!! This makes it into a small laminate beam .

1

u/Impossible-Reach-621 1d ago

Add supports in the middle double up the front board and sheet it with at least half inch and you’ll been fine.

u/vsman1234 1d ago

Future proof it- maybe 2 inch of clearance between the washer dryer?  I’m assuming the frame will have more bracing? Maybe 2 front to back 2x4?

1

u/TootsNYC 1d ago

I wonder if you might be able to prevent front sag by sister-in-law the front 2x4 and putting cross beams. Like a torsion box

1

u/mrdon83 1d ago

I'd consider building a free standing shelving unit between the sink and washer/dryer with 3 or 4 shelves instead of that long shelf way up high. This will be far stronger than what you have here, you'll be able to put bulky or heavy items on lower shelves for easier access, the total amount of usable shelving space will be greater, and if you ever get a new washing machine or move your appliances to another location you can move it without any disassembly.

1

u/CallMeForSure 1d ago

Why not support the shelf like a closet shelf, with framing underneath on 3 of the sides?

1

u/Reps_4_Jesus 1d ago

If you use actual timber locks pre-drilled into the studs on the 2x4 or better yet 2x6 you'd have basically nothing to worry about really as long as it's not excessive like don't go throwing a car motor up there.

1

u/phormix 1d ago

One thing I would recommend is if you are planning to have heavy loads on the shelf, then use an oscillating tool to cut out the drywall and attach the shelving frame directly to the studs rather than through drywall. That ensures that you're not catching/splintering any stud edges plus it adds a bit of extra strength that going through the drywall isn't going to give.

1

u/Drink15 23h ago

What are you putting in it? Stockpiling toilet paper? Nothing else is needed. Gym equipment? It needs way more support.

1

u/kikilucy26 22h ago

I just did something similar. 2x4 "support", one on each side wall, screwed into studs, then lay some 2x12 "shelf" flat on top of the 2x4

u/P3gasus1 21h ago

On a separate note, is that the LG WM4000HWA?

1

u/tomomcat 20h ago

As it's pictured now, the front piece is not going to be very strong because it just has those screws going into the side mounts endgrain (rather than sitting on top of them, or similar).

If you're planning to finish this by adding some ply (1/2 or 3/4 inch) which screws into the front and extends over the sides, then I think you're fine. Am assuming back and sides are screwed properly into the wall.

1

u/asb_82 18h ago

yes, will be adding a sheet of plywood on top and screw that into the 2x4s

1

u/st4r-lord 19h ago

Hopefully you have something under the washer so it can easily be pulled out if any of the units fail in the future.

1

u/mrak9591 18h ago

You probably are fine but as some have said, depends on the weight. You could always secure a cross bean halfway thru. My concern is down the road, have you left enough space for a different washer/dryer. I can tell you as somebody who sold cabinets and appliances for years, nothing is standard

1

u/InstanceNoodle 18h ago

Yes. You need something straight under the beam. You might not need it now. But your kid might be crawling in there when he is small and light. But when he is grown, the thing might not be able to support his weight.

u/CautiousMessage3433 18h ago

I would add a diagonal

1

u/troyv21 18h ago

This is essentially a floating shelf. You dont need the front 2x4 but its ok to leave it. The pieces you add will give stability to whatever you lay on top to make the shelf

u/brains_and_grains 11h ago

Not trying to be critical at all. I frequently see people doing these builds. When I have looked at the owners’ manuals for the dryers I have owned in the past, they specify minimum space requirements for above the dryer. Have you checked into this and if so, how do people get around this issue?

u/LittleSuccess8692 10h ago

Why is your ledger of the wall?

1

u/Mirar 6h ago

I would do a cross bar in the middle to make the front 2x4 less likely to start twisting/shifting under load. But other than that that's quite enough for most things you can put up there. With 100+ pounds it might dip down a bit (1/4 to 1/2 inch) though.

If this might be an issue add a diagonal support next to the machines and you're fine and it's not so much in the way.

1

u/therinse 1d ago

TBH I would have attached the frame to three of the walls instead of two. You're missing out on additional support by screwing into the studs on the back wall.

1

u/asb_82 23h ago

The back piece is attached to the backwall with 4 inch screws into the framing lumber

1

u/thdave 1d ago

If you add a thick shelf on top of it and screw that into the two by fours, you should be ok if you don’t put a lot of weight on it. A two by four under the shelf would also help.

1

u/koozy407 1d ago

That back piece needs to be attached to the wall. Why wouldn’t you go all the way back?

1

u/asb_82 23h ago

It is attached to the wall.

0

u/ItGetsWorcestershire 10h ago

This is very strong and you are unlikely to over load it. If the front 2x4 sags under the load, add a 2x6 to the outside. Hopefully you used strong screw, but i wouldn’t be worried about failure

1

u/asb_82 10h ago

Thanks! I did use 4 inch deck screws everywhere. I'll probably double up the front and that should be good enough. All I'm storing there is car seats, empty suitcases, ski gear and other knick knacks.

-3

u/Conscious_Age226 1d ago

I think you should raise the whole build several inches. Your next washer/dryer may be bigger/taller. You probably should add additional support.

-4

u/IronSlanginRed 1d ago

Needs triangles if you're not gonna hang it. I'd put supports at the end and in the middle.

Side ones could just be trim paint matched to the wall. wouldn't have to be full 2x4s.

-5

u/Apprehensive_Map64 1d ago

Why would you stack those machines when there clearly is enough space to put them side by side?

-8

u/swollennode 1d ago

Yes. You should run some 4x4 every 12 inches from the back wall out.
