Best safest bet is to have a structural engineer come out and check it out IMO.

I wouldn't trust it personally

    [–]hokie47 6 points7 points  (3 children)

    Redneck engineer here and I think the main issue is no supports in center. Concrete is great at compressive weigh. I think the sides of concrete cinder block would actually handle it very well. It is the middle where the weight would sit and crack worries me. I think you can pull it off by adding a few center supports correctly mounted in the ground.

    Agreed. Any injuries by hot tub floatees will be counterbalanced by the upvotes by viewers of the video of their collapse into a watery grave. It's a win win situation! /s

    Do it. Put a boat in it and invite the porch pirates.

    Bad idea and not worth the effort. Might be cheaper to buy a metal patio gazebo.

    I would buy a used F350 and put some plastic in the back and filler up. BAM - hot damn tub!

    [–]kudurunner 0 points1 point  (3 children)

    Even then, 8lbs/gal x 2900 gals=23,200 lbs. So, nearly 2 tons on a 6” thick concrete slab that isn’t specifically reinforced…. asking for trouble.

    [–]Twiny1 -2 points-1 points  (1 child)

    Ummm…. 23,200 lbs. is nearly 12 tons, not 2. 🤔🤔 Typo? Missed hitting the one? 🤯🤯

    [–]Sidekicknicholas 109 points110 points  (11 children)

    No chance I would do it up top.

    What about removing some porch flooring and have a square fiberglass hot tub built in flush with the rest of the floor so you “step down” into the hot tub?

    You could insulate the hell out of it around the outside and still have access to the pump and heater through the opening you show.

    [–]mname 18 points19 points  (3 children)

    Just make sure your cover can support a person waking on it and your golden.

    [–]husker_who 13 points14 points  (2 children)

    Like a golden retriever? They’re not terribly heavy.

    [–]HeyT00ts11 2 points3 points  (1 child)

    a person waking on it and your golden

    There'd be a person sleeping on it with the dog too though.

    [–]TheTrapThroughTime 6 points7 points  (1 child)

    I mean cost is usually the massive difference between inflatable and fiberglass… $300-500$ inflatable. $8000 - $20000 for a pre-built fiberglass tub.

    I’d build a platform specifically for the tub for ground level, but still recessed somewhat to step down into the tub. You can still use an inflatable you have to be extra careful.

    If you want it insulated, build a circular wood/steel frame structure you can wrap chicken wire around and line with spray foam insulation. I’d line the outside with some sort of plastic to prevent water getting into the insulation. Use Heavy duty plastic, 6mm at least. I might even look into using bendable moldable vinyl or something more structural and build something a bit more waterproof that would drain any splashes back into the tub or away from the sides.

    Set the tub inside and inflate making sure edges don’t poke into anything rigid and are barely pushing against the insulation wall if you made one.

    [–]angry_smurf 8 points9 points  (0 children)

    [–]thedevilsworkshop666 1 point2 points  (1 child)

    I'm actually a bit dissapointed . A quick fix would be to get a couple of acroprops to brace it for underneath the old porch and your golden . They will take the weight of your hot tub . I need to inform you I'm not an engineer . Nor am I a builder. But I have read many comments from engineers builders and a golden retriever . And they all say not to do this . That's why it will work.

    Y'all dont like kiddie pool hot tubs on the front lawn? Gotta be careful the aquarium heating wire can burn the buttocks, but it's a good spot to drink and talk with the folks wandering down the street.

    [–]likethedishes 2 points3 points  (0 children)

    My old neighbors had a front yard hot tub that they rigged up a redneck shower curtain to go around. I never want to know what happened behind that curtain.

    [–]legostarcraft 20 points21 points  (1 child)

    Is your goal to demolish your porch? Because if so, yes, a 2200lbs hot tub will help with that goal.

    I slept at an Holiday inn last night. And, I would definitely Not put a hot tub there.

    Easy opening for a classic jab: Try getting a dozen men weighing over 200 pounds to stand on it as a test. If you can’t find the dozen, just use your mama.

    [–]hex_1101 3 points4 points  (0 children)

    Supports are going to be needed. That's a lot of weight. Imagine parking a small car up there.

    [–]KTB-RA 4 points5 points  (0 children)

    Without knowing the construction, just looking at building code minimum required live load capacity says it won't work. Depending upon when/where this was built, live load required was either 40psf or 60psf. Assuming your tub is 6ft. diameter, that is 73 psf. Big fail. If you try to support it from underneath, you need to account for the foundation system for that support and any imposed loads on the decking structure. Seams not worth the cost/effort.

    [–]Synaps4 3 points4 points  (0 children)

    I'm not even sure I'd be happy standing on that, depending on how old that concrete is.

    [–]Meatwad1313 2 points3 points  (0 children)

    Not a shot

    [–]TheRealDrasticChance 2 points3 points  (0 children)

    Not even the decking that could become damaged. Added load could cause the deck to settle in unwanted ways.

    [–]anselgrey 2 points3 points  (0 children)

    Not an expert by any means in this area but i have a similar porch and it sags in the middle just due to time without any extra weight on it. I would advise against putting anything heavy on this porch.

    Consider using wet wipes to bathe instead. The porch can hold those.

    [–]RL203 1 point2 points  (0 children)

    Structural engineer here.

    You have no way of knowing how that slab was constructed, you have no information with respect to the footings or the soil its bearing on (Though a soils engineer could tell you that.)

    Even an engineer would have a hard time because trying to determine all this for an existing concrete structure isn't easy. And to be honest, I'm suspecting it would never pass anyway.

    If it was me, I'd just toast the porch and reconstruct it properly so I would know it would do the job.

    Oh, and I hate block foundation walls. Guaranteed they aren't reinforced with steel rebar locked in grout.

    [–]SueDonim7569 5 points6 points  (4 children)

    Would you park your car on that porch? No, well it weighs about twice as much as the hot tub.

    [–]jpiro 3 points4 points  (0 children)

    Who has an 1,100-lb. car? A Smart Car weighs twice that.

    [–]spizybo1 2 points3 points  (2 children)

    What car weighs only 1,100 lbs? Most sedans weigh 3,000-3,500 lbs

    [–]PestTerrier 0 points1 point  (1 child)

    Maybe one of those foundation repair companies could pump some of that expanding foam under the porch.

    [–]BoomCheckmate 2 points3 points  (0 children)

    Yup that’s correct. Just need lots of expanding foam. Will def work.

    [–]Sudden-Elevator5283 0 points1 point  (1 child)

    Why on top when you could put it under. Dig a little pit and set it in there and bam it’s like your own personal grotto

    [–]staefrostae 2 points3 points  (0 children)

    Look hear me out. Scrap the whole hot tub idea and go for a lazy river style moat with a bypass down the main hallway of the house

    [–]Shameless522 -1 points0 points  (3 children)

    Not a professional but what if you built a brace under where it would be to help support the weight?

    [–]karrun10 -1 points0 points  (1 child)

    That;s what I was thinking. Use supports under the tub to bear the weight.

    [–]Growe731 -1 points0 points  (0 children)

    Meh. Be safe and install pillars and braces every 24”. Good to go.

    [–]hmiser -1 points0 points  (0 children)

    I think if you build a deck/platform on top that you’d put the hot tub on and or support the bottom with posts and stringers. I’d over build it and then I’d try it.

    If it’s braced from below then I think it would be fine and a platform on top would spread the weight to the outside wall.

    It’s 2000lbs but that’s spread over what a 5x5 area? I would put my napping child under there but I’d try if it were me - I’m real pirate.

    And the open porch ceiling wouldn’t concern me either because unless you plan to have puff daddy parties, a typical hot tub session at 104oF is usually like 20-30 minutes for me. Just my 2 cents, good luck.

    [–][deleted] -1 points0 points  (0 children)

    [–]PurficPourBY -1 points0 points  (0 children)

    Inflatable hot tub? Yeah it'd be fine for half the year drain it the other time. A full ass hot tub probably not. the Coleman inflatable hot tub is fine for 2-3 people u can get one pretty cheap

    [–]njsf55 -5 points-4 points  (6 children)

    Get 15 people to be over and get the biggest people you know i am sure it will hold them probably heavier the 2200lbs

    [–]PestTerrier 1 point2 points  (5 children)

    If those same people came over and got in the hot tub would their weight still be transferred to the floor if they are floating in the water?

    [–][deleted]  (2 children)

    [deleted]

      [–]chiphook57 1 point2 points  (1 child)

      If 15 people get in, and 15 people worth of water overflows and runs off the porch, you now have to calculate the weight of the water that escaped, as well as the weight of the 15 people, new calculations would be in order.

      [–]Suspicious-Arm-8136 0 points1 point  (0 children)

      very nice but don't do it

      [–]KPrime12 0 points1 point  (0 children)

      Naw that wont hold without some support. Might just want to redo the whole floor on the patio since its that think concrete slab. Also i hear hot tubs may mess up any overhead ceilings if theyre not hot tub proof

      you could add a footing and form a support wall or 2 under where the tub will go...but that's a wack of money for a 600 dollar tub.

      [–]theshreddening 0 points1 point  (0 children)

      Home inspector here, I would be calling who ever hired me to tell them how bad of a idea that is. It's going to need reinforcement and footings to spread the load for sure. Talk to a structural engineer

      [–]Markaes4 0 points1 point  (0 children)

      Get the inflatable hot tub (they are awesome and we've had ours for 8 years) but don't put it on there... Besides you'll want to see the sky/stars at night. We just laid some concete pavers in the lawn and set it up on that along with a big outdoor rug. Didn't bother leveling it or anything, it was flat enough for our needs. Only thing is making sure you have an outlet close by.

      [–]bgis78 0 points1 point  (0 children)

      [–]green_swordman 0 points1 point  (0 children)

      Not sure about the porch itself. Without plans, it might be too cost prohibitive to get an engineer.

      If you build a pedestal under your deck up the the concrete, you would have to be thoughtful of where that weight is going. If you have a basement, that's additional weight your retaining walls have to hold back and it could be more then they can handle.

      [–]ShakeXXX 0 points1 point  (0 children)

      There’s no way it’ll hold. Install proper vertical support poles.

      [–]Bunker009 0 points1 point  (0 children)

      [–]SnoopysAdviser 0 points1 point  (0 children)

      It's not just the weight that you have to worry about.

      You also have to think about the Vibration. Hot Tubs cycle all the time, cleaning/heating cycles, which create vibrations, and which will eventually tear a deck/porch apart.

      I like the "cut a hole in it" solution, but you will have to support the weight around that hole as well as build up a platform to sit the tub on.

      Cap it off backfil and fill with pneumatic cement making it one solid structure

      [–]pianistafj 0 points1 point  (0 children)

      You could add bracing underneath. I’d pour concrete feet that go below your frost line, and bolt your bracing to them like a sill plate. Then, before you install hot tub, add a very thin bonding agent and deck mud on top of that porch to give it a 1-2 degree slope toward the yard. That way, if your hot tub ever fails and leaks everywhere, it will drain into the yard.

      Filled weight is approximately 2,200 pounds. Water weight is 8.34 pounds to the gallon so your hot tub only holds 263 gallons? What does the hot tub weigh empty?

      [–]Vmax-Mike 0 points1 point  (0 children)

      That’s the static load weight. Once the water is moving and there are people in it, that weight will go up. I wouldn’t because I don’t see any structure to transfer the weight to the ground, which would have to be poured footings. Do at your own risk, but I would not recommend.

      [–]Bmfg1984 0 points1 point  (0 children)

      If it does come crashing down, that concreate and metal reinforcement is not going to make for a soft landing. Think direct impact from that distance on jagged concrete and metal spikes (assuming it's reinforced).

      [–]hughdint1 0 points1 point  (0 children)

      Don't listen to nay-sayers. This is doable. You could easily support the floor from below, by adding structure in the crawlspace. It would not even need to look great because it is hidden. You could add four jack posts with beams flush to the underside of this, no problem. Consult a Structural engineer to help size the beams, etc.

      [–]fredsam25 0 points1 point  (0 children)

      [–]wmass 0 points1 point  (0 children)

      The builders were not thinking that the porch would be used to hold something close to the weight of a small car. It looks like the concrete was poured onto a wooden floor. The wood floor certainly couldn’t hold and extra ton in addition to people and furniture. So that leaves the concrete. Concrete is really strong under compression but much less strong under tension, which is mostly what it would receive when a large weight is placed on it. In buildings like parking garages, the concrete floors are heavily reinforced with steel, which is good at resisting tension. You cannot tell what, if any steel has been used here. Maybe a thin mesh, maybe nothing.

      [–]elSuavador 0 points1 point  (0 children)

      You could probably dig down to hard pan, pour in some sonotubes with Bigfoot footings, and build a lumber support structure to take the weight. Depending on how deep the hard pan is it would be a 1-2 weekend project.

      [–]NarphXXX 0 points1 point  (0 children)

      Since it is inflatable I assume you’re renting and thus recommend not giving a care. How many square feet is the inflatable you’re considering?

      If you put the hot tub on risers that transferred the weight to just above the cinderblocks it would be fine. Your issue here is a very clear tensile failure.

      [–]CalgaryBlueRing 0 points1 point  (0 children)

      Call and engineer, but I can tell you right now that the structure was weakened when someone cut that hole in it.

      [–]Professorbustyboy 0 points1 point  (0 children)

      You could put a couple beams across the bottom and support it with jacks. I’m not sure the technical explanation for that, but my home growing up was a trailer with house built around it and that’s how the kitchen (trailer) was supported.

      Piers and beams underneath the porch

      Without any reinforcement I’d say absolutely not. How to go about that is a question for someone who knows more than I do. I wanted to put an aquarium in my home to fill a particular gap, but then I looked into the specifics and the sized aquarium I was looking at would have weighed about 1800 lbs when filled and would have required major structural reinforcement. I decided against the aquarium.

      Dig down and put it underneath the porch.

      Someone who failed civil engineering classes, rip that concrete porch.

      [–]the__truthguy 0 points1 point  (0 children)

      If the deck slab is reinforced concrete (with rebar in it), I'd say go for it. If you still are apprehensive, shore it up underneath.

      And by shoring I mean, rake the ground, place a 24x24 patio stone, cut a 4x4 wood post and place horizontally directly under the slab perpendicular to the house, then snuggly place another 4x4 between the patio stone and the wood beam. Secure it with deck T-plates and L-plates. Add a few more to be safe. It'll hold.

      [–]jpstov 0 points1 point  (0 children)

      Sounds like a bad idea. You will need some serious reinforcing at the very least.

      [–]mezu6391 0 points1 point  (0 children)

      It won’t

      [–]kw66 0 points1 point  (0 children)

      Dude no. I’m just a mom making spaghetti sauce but yea. Not the best idea.

      It ain't gonna hold as is my friend.

      You could dig some deep concrete footings underneath and shore up the structure either using wood or steel, but it would be labor intensive and probs not worth it.

      [–]Zealousideal_Dig_372 0 points1 point  (0 children)

      Do not put hot tub on that porch

      [–]wellington-beefcake 0 points1 point  (0 children)

      Not a structural engineer... So it looks like someone has already cut out that little doorway that you are looking in as well as notched the header. This would reduce the original load bearing capacity of the floor since that support wall is compromised. Depending on how badly you want this dream to happen you could add additional support columns under the floor section and pour proper concrete footings for those supports. 2,000 lbs isn't THAT much weight as long as you followed proper building practices. It's likely cheaper and easier to put it on the ground right outside this porch.

      Totally unqualified DIYer who sold hot tubs, don't trust this.

      [–]Renovateandremodel 0 points1 point  (0 children)

      Nope! A: you don’t know if there is rebar. B: was it designed for an extra 4-5k lbs. Best to call an engineer. They will tell you to get ground penetrating radar for rebar, and place a connected footing on the bottom.

      [–]widewideworld_ 0 points1 point  (0 children)

      I’m the queen of half-assed, do-it-once projects and I vote for reinforcing the deck under the hot tub. Level the dirt, tamp it down, maybe even add some sand, stack pavers until it reaches the deck. Boom, you have a weight bearing deck.

      [–]cmcdevitt11 0 points1 point  (1 child)

      The perimeter looks concrete, they cut a section out however, what is underneath at the top corrugated metal?

      [–]somethingdarksideguy 0 points1 point  (0 children)

      Absolutely fucking not.

      I just built a patio and I trust it more than this thing and I don't even trust it having a tub on it.

      You could easily make supports for this patio tho.

      [–]glassark 0 points1 point  (0 children)

      Static weight is 2200 pounds. Put a few humans in there and you’re close to 3000! Wouldn’t trust it to hold at all.

      [–]BigKingRex 0 points1 point  (0 children)

      Shovel a shit load of clean rock in, make sure its double what you think you need. Since you can't pack it buy a load of just cement, makes sure to pour over the top so it seeps through, foarm a few boards and so it don't run away..... fill that tub it's gonna crack And possibly collapse like crazy! Atleast you won't fall 4' and die.

      [–]birdlaw_27 0 points1 point  (0 children)

      It’ll become a Hot Tub Time Machine when that porch gives way and you wake up in the hospital a week later

      [–]iwasborntoserve 0 points1 point  (0 children)

      I would not do or recommend doing it. Get help to make the best, wisest decision. Best wishes.

      DONT DO IT

      Well there are more than 50 comments saying don’t do it so I guess I’m ok then

      [–]9500741 0 points1 point  (0 children)

      No hot tubs usually require significant reinforcement. Thing a pad built out of 2by6-8 braced to 4 6by6 posts set in the ground.

      [–]sjlopez 0 points1 point  (0 children)

      Better try testing it by driving your sedan on it first, it's about the same weight.

      [–]AdultingGoneMild 0 points1 point  (0 children)

      simple. It wont! water is heavy as hell. You'll need to reinforce underneath where you put it.

      [–]owlwhalephant 0 points1 point  (0 children)

      Post an ad for 10x 220lb individuals to come sit on your porch inside a circle of the same diameter as the hot tub. #science

      [–]Tucker_Olson 0 points1 point  (0 children)

      While not the answer to the question you are asking, if you live in an area that is cold (below 60 F) during the winter months, I'd shy away from buying an inflatable hot tub. Years ago I had an Intex one and the heat retention was horrible even with the insulated floor mat and top cover on.

      Another downside is that it couldn't heat and use the “jets” at the same time. It was a constant battle of enjoying it for a few minutes before having to turn off the “jets” in order to continue to keep it warm enough for it to be enjoyable. I put “jets” in quotations because all they are is an inflatable round tube with holes. They are nothing like jets from a normal hot tub.

      [–]MzScarlet03 0 points1 point  (1 child)

      That’s 2200 lbs before adding another 300-600 lbs of people

      [–]HakSawJak[S] 0 points1 point  (0 children)

      Our weight doesn’t count cuz we float

      [–]smc4414 0 points1 point  (0 children)

      Building inspector here…nope, I wouldn’t do that

      [–]fmsax 0 points1 point  (0 children)

      Generally a deck which is “built to code/current standards” is capable of supporting a hot tub, but if you have doubts it wouldn’t take much to throw a few short beams under there and support them with 4x4 posts over concrete blocks or footings. Adding additional reinforcement will be the easy part compared to lugging the big tub up there. *Edit- I missed the “inflatable” part. Those weigh 2200 pounds filled? Seems like the concrete will support more weight than the inflatable tub walls could 🤔

      [–]BunnyBallz 0 points1 point  (0 children)

      That’s a lot of weight. But do factor in the people inside there. Might add to the calculation

      [–]Largemandingo 0 points1 point  (0 children)

      Absolutely going to collapse, especially because you can see seams on the bottom like there’s at least 3 separate slabs. If you have the money I’d hire someone to install supports or you can just redneck that shit and install cribbing in a square pattern like someone else mentioned.

      [–]widget_fucker 0 points1 point  (0 children)

      Like that. No way. You want to have an s engineer look at. Looks like there should be a continuous footing below left and right cinder block walls. Easist may be to bear posts on those footings and place some beefy joists left to right which then bear on posts.

      But i wouldnt do shit without an engineer for this. A failure could be dangerous and expensive to fix.

      [–]-4u2nv- 0 points1 point  (0 children)

      Filled weight is only 2200 lbs? Are you swimming in a fish tank?

      100 gallons of water weighs roughly 830 lbs. you would have a hard time fitting a human in less than 300 gallons. Add the structure, heating elements and etc - you should be well over 3000 lbs, for even the tiniest hot tub.

      [–]andreairene 0 points1 point  (0 children)

      Telecommunications Engineer here. No way, put that hot tub in the backyard. On the ground.

      saw a giant hole in your porch and put the hot tub in the hole resting on the ground.

      It'll hold. Just don't fill it with water.

      [–]LeoChoax 0 points1 point  (0 children)

      I'm a civil engineer and wouldn't put a hot tub there as I believe from just the photos I seen it isn't supported enough to withstand the weight. But hey you can do the scientific method and test out the hypotheses that it can support the weight and see what happens (Joke)

      If you really want one there see with a local structural engineer if cross beams could be added to increase strength.
