Everybody desires to have a effervescent out of doors jacuzzi on their deck. It’s the last word dream! However right here is the scary half—a sizzling tub full of water and 4 adults can weigh over 4,000 kilos. That’s like parking a full-size SUV in your wood deck. I’ve seen previous decks fold like a garden chair as a result of somebody forgot to test the “math.”
On this information, I’m going to point out you learn how to have that lovely, Pinterest-worthy spa with out ending up in your neighbor’s yard. We’re going to discuss weight, wooden, and water. From checking your beams to choosing the proper spot, listed below are 15 tricks to maintain your “soak” secure and classy.
1. The “2-Ton Elephant” Actuality Examine
The very first thing it’s worthwhile to understand is that water is heavy. A typical 4-person sizzling tub holds about 300 to 400 gallons of water. At about 8 kilos per gallon, that’s 3,200 kilos only for the water! Add the load of the bathtub itself and 4 of your mates, and you’re looking at over 2 tons.
My 20-year rule of thumb: In case your deck was constructed just for “folks strolling,” it isn’t robust sufficient for a jacuzzi. It’s essential deal with it like you’re constructing a basis for a small home, not only a place for a BBQ.
2. The “Inflatable” Secret (Wait, It’s Heavier?)
Individuals suppose that as a result of an inflatable sizzling tub is “gentle,” it’s lighter. Fallacious. As a result of they’re typically deeper or wider than hard-shell tubs, they will truly maintain extra water and put extra stress in your deck.
Don’t let the gentle plastic idiot you—the load in your wooden boards is simply as harmful. If you’re placing an inflatable tub on an previous deck, you continue to must observe each security rule on this put up or put together for a really costly “crash.”
3. Find the “Bearing Beams”
Before you purchase something, go beneath your deck with a flashlight. You’re searching for the Beams (the massive horizontal items of wooden) and the Posts (the vertical legs).
In case your tub is sitting proper over a important put up, that’s good. Whether it is sitting in the midst of a “span” with no help beneath, that could be a catastrophe ready to occur.
For a 4,000-pound tub, you need these beams to be thick—no less than double 2×10 or 2×12 pressure-treated wooden.
4. The 12-Inch Joist Rule
Most traditional decks have Joists (the ribs underneath the floorboards) spaced 16 inches aside. For a sizzling tub, that’s too huge.
You need your joists to be spaced 12 inches aside and even nearer. Consider it like a mattress body; the extra slats you might have, the extra weight it may maintain.
My ideas: In case your joists are 16 inches aside, you possibly can truly add “sister” joists (nailing a brand new board proper subsequent to the previous one) to double the energy with out rebuilding the entire deck.
5. Nook Placement is King
If in case you have a alternative, all the time put your sizzling tub in a nook of the deck that’s connected to the home. Why? As a result of that’s the place the deck is strongest.
You’ve gotten the help of the home’s “ledger board” on one facet and two nook posts on the opposite. Placing a sizzling tub within the very heart of a giant, floating deck is probably the most harmful spot you possibly can choose. It’s all in regards to the physics of “load distribution.”
6. Watch out for “Wooden Rot”
I’ve seen decks that look robust however are literally gentle inside. Take a screwdriver and poke the wooden beams and posts underneath the deck.
If the wooden feels gentle like a sponge, you might have wooden rot. Including 4,000 kilos to rotten wooden is like constructing on sand. For those who see white fungus or gentle spots, it’s worthwhile to substitute these boards earlier than you even take into consideration a jacuzzi.
7. The Concrete Pad Various
Typically, the most effective place for a sizzling tub on a deck isn’t on the deck in any respect. In case your deck is low to the bottom, I typically recommend slicing out a sq. of the wooden flooring and pouring a 4-inch thick concrete pad on the grime.
Then, you set the new tub on the concrete and construct the deck round it. This provides you the “built-in” look (very Pinterest-style!) however places zero weight in your wood construction. It’s the most secure method to go, interval.
8. Weight-Distributing Spa Pads
For those who can’t do a concrete pad, purchase some Plastic Spa Pads . These are laborious plastic tiles that go underneath the bathtub. They assist unfold the load throughout extra floorboards so the stress isn’t multi function spot.
It’s a small funding (often underneath $150) that may stop your deck boards from cracking or sagging underneath the heavy weight of the spa.
9. The “Zap” Issue (Electrical Security)
Water and electrical energy are a lethal combine. You can not simply run an everyday orange extension wire out of your kitchen to a sizzling tub. For an actual jacuzzi, you want a devoted 220V line with a GFCI shut-off field (I just like the Eaton or Siemens manufacturers). For an inflatable tub, you should use 110V, but it surely nonetheless must be by itself circuit. My recommendation is to Name a professional—this isn’t the place to “DIY” and hope for the most effective.
10. Drainage is Every little thing
When folks get out of a sizzling tub, they bring about gallons of water with them. If that water sits in your wooden deck, it would trigger rot in months, not years.
Be certain that your deck has a slight slope (about 1/8 inch per foot) so the water runs away from the home. I additionally advocate utilizing a high-quality waterproof sealer on the wooden across the tub twice a 12 months to maintain the moisture out of the grain.
11. The “Step-Up” Design Hack
Don’t simply plop your out of doors jacuzzi on high of the deck. Construct multi-level steps round it. You should use these steps to cover the ugly plastic sides of the bathtub and to cover {the electrical} wires. For those who construct the steps huge sufficient, in addition they double as additional seating for buddies who simply need to hang around close to the water with out getting moist.
12. Privateness With out the “Cage”
No one desires to soak whereas the neighbor is mowing their garden two ft away. As an alternative of constructing a large, ugly wall, use Slatted Wooden Screens or Tall Planter Packing containers.
A row of 6-foot tall Arborvitae bushes in giant pots offers you whole privateness however retains the “backyard” really feel. It makes your spa really feel like a secret resort in the midst of town.
13. Lighting for the “Vibe” and Security
You’re going to be utilizing this tub at night time, so don’t depend on a shiny porch gentle that draws each bug within the county. Use low-voltage LED deck lights constructed into the steps and the floorboards.
14. Winter Entry (The “Run of Disgrace”)
Take into consideration the place you set the bathtub in relation to your again door. In the course of January, you do not need to stroll 30 ft throughout a freezing deck in a swimsuit. Hold the bathtub inside 5 to 10 ft of the door. Belief me, your future “chilly” self will thanks for this one.
15. Get a “Professional” to Signal Off
I do know, I do know—we like to do issues ourselves. However in case you are placing a 2-ton tub on a 10-year-old deck, spend the $200 to rent an area structural engineer or a grasp carpenter for one hour. Allow them to have a look at your beams and posts.
Having an expert inform you “Sure, that is secure” is price each penny in your peace of thoughts. It’s higher to pay for an inspection now than a brand new deck (and a brand new tub) later!
FAQ:

A: Provided that you examine it first! Previous wooden will get weak. If the deck is greater than 10 years previous, you virtually actually want so as to add additional posts and beams to deal with the load.
Q: Is a concrete pad higher than a deck?
A: Sure, 100%. Concrete doesn’t rot, and it doesn’t sag. In case your deck is low to the bottom, all the time select a concrete pad.

A: For those who do it your self, you possibly can add additional help for $300 to $500 in lumber and {hardware}. It’s rather a lot cheaper than fixing a collapsed deck!
