What Happens to Hot Tubs After Removal?
Your hot tub is gone. The crew loaded it up and drove away. But then what? Does it just end up in a landfill somewhere?
The answer might surprise you. Hot tubs are actually more recyclable than most people think. Here's what happens to old spas after they leave your backyard.
What Hot Tubs Are Made Of
A typical hot tub contains multiple materials:
Shell (acrylic or fiberglass). The shiny tub part you sit in. Usually reinforced with fiberglass backing.
Cabinet (wood or synthetic). The outer housing, typically wood panels or composite material.
Foam insulation. Most tubs are filled with spray foam insulation to retain heat. This is the bulkiest material by volume.
Plumbing (PVC). The pipes, jets, and fittings that circulate water.
Mechanical components (metal and plastic). Pumps, heaters, control panels, and wiring.
What Actually Gets Recycled
When properly processed, several components can be recycled:
The reality: a responsible removal company will separate recyclable materials rather than dumping everything together. This takes more effort but keeps usable materials out of landfills.
What Typically Goes to Landfill
Not everything can be recycled:
Spray foam insulation. This is the biggest waste component. Foam insulation isn't recyclable and makes up a significant portion of the tub's volume.
Fiberglass-reinforced shells. When acrylic and fiberglass are bonded together, separation isn't cost-effective. These usually go to landfill.
Contaminated materials. Anything damaged by mold, chemicals, or rot typically can't be recycled.
Mixed materials. When different plastics or composites are fused together, separation isn't practical.
Where Hot Tubs Go in the Boise Area
In the Treasure Valley, hot tub materials typically go to:
Ada County Landfill (Hidden Hollow). Non-recyclable materials end up here. The facility accepts bulky waste like hot tub shells and foam.
Local metal recyclers. Boise has several scrap metal facilities that accept copper, steel, and aluminum components from hot tubs.
Transfer stations. The Boise area has several transfer stations where materials get sorted before going to their final destinations.
Specialized recyclers. Some electronics and mechanical components go to e-waste recyclers.
Can Old Hot Tubs Be Resold?
Sometimes, but not often:
Working tubs in good condition. If your hot tub still works and looks decent, you might be able to sell it yourself. List it on Facebook Marketplace or Craigslist. Buyers typically want tubs under 10 years old that have been maintained.
The catch: Hot tubs are hard to move. Most buyers expect delivery, which creates a logistics challenge. And prices for used hot tubs are low—often a few hundred dollars at most.
Donation. Rarely practical. Most charities won't accept hot tubs due to liability concerns and the difficulty of resale.
Reality check: If you're calling for removal, the tub is probably old, non-working, or not worth the effort to sell. And that's fine—recycling the materials is still better than leaving it to rot in your backyard.
How to Choose an Eco-Conscious Removal Company
If environmental impact matters to you:
Ask about their disposal process. Do they separate materials? Do they work with recyclers? A company that just dumps everything in the landfill is doing the bare minimum.
Avoid illegal dumping. The cheapest quote might be from someone who dumps in a field or abandoned lot. Besides being illegal, this creates environmental problems.
Licensed and insured matters. Legitimate companies use licensed disposal facilities. This ensures materials go where they're supposed to go.
The Bottom Line
Hot tubs aren't 100% recyclable—the foam insulation and composite materials usually end up in landfills. But metal components, wood, and some plastics can be recycled.
A responsible removal company will separate and recycle what they can rather than dumping everything together. It's a small difference in the grand scheme, but it's the right thing to do.
Either way, getting that old hot tub out of your yard is better than letting it sit and deteriorate for years. At least this way, the recyclable parts get a second life.
