Removing an old hot tub can seem daunting, but with the right approach and a rented dumpster, it's a manageable DIY project. Whether your spa is broken, outdated, or you're simply reclaiming backyard space, this guide covers everything you need to know about hot tub disposal.
What Size Dumpster Do You Need for Hot Tub Removal?
Most residential hot tub removals fit into a 15-yard or 20-yard dumpster when properly broken down. The hot tub shell must be cut into pieces—you can't dispose of it whole.
15 Yard Dumpster Most Common
Best for: Standard 2-6 person hot tubs (6x6 to 7x7 feet)
- Dimensions: 16' × 7.5' × 4.5'
- Holds about 6 pickup truck loads
- Perfect for most residential spas
$350-$425 average
20 Yard Dumpster
Best for: Large 7-8 person hot tubs or swim spas
- Dimensions: 22' × 7.5' × 4.5'
- Holds about 8 pickup truck loads
- Extra room for deck removal debris
$400-$500 average
💡 Pro Tip: Breaking It Down
A hot tub that looks massive becomes surprisingly compact when cut into pieces. The shell, foam, and wood frame compress well. Most homeowners overestimate the dumpster size needed.
Hot Tub Disposal Costs: Dumpster vs. Junk Removal
| Disposal Method | Cost Range | Pros | Cons |
|---|---|---|---|
| Dumpster Rental (DIY) | $350-$500 | Cheapest option, work at your pace, 7-10 day rental | Physical labor required, need tools |
| Junk Removal Service | $400-$800 | No labor, done in hours | More expensive, scheduling required |
| Dump Runs (Trailer) | $100-$200 + time | Lowest cost if you have trailer | Multiple trips, heavy lifting |
Step-by-Step: How to Remove a Hot Tub
-
Disconnect the Power
Turn off the circuit breaker for your hot tub. For 220V hardwired units, you may want an electrician to disconnect it properly. Never work on a hot tub with power connected. -
Drain All Water
Locate the drain valve (usually near the bottom) and attach a garden hose. Direct water away from your foundation and any plants sensitive to chlorine/bromine. A submersible pump speeds this up significantly. Expect 300-500 gallons (1-2 hours to drain). -
Remove Access Panels
Unscrew or pop off the side cabinet panels. Most use Phillips head screws or plastic clips. This exposes the pump, heater, and plumbing. -
Disconnect Internal Components
Remove the pump, heater, control pack, and blower if equipped. These can sometimes be sold online or recycled for parts. Cut PVC plumbing connections. -
Cut the Shell Into Sections
Using a reciprocating saw with a long demolition blade, cut the acrylic shell into 2-3 foot manageable pieces. Cut through the shell and underlying foam insulation together. -
Dismantle the Frame
The wood or metal frame can be pried apart or cut with your saw. Remove any remaining insulation and the hot tub base. -
Load the Dumpster
Load shell pieces flat against the bottom to maximize space. Stack frame pieces and cabinet panels on top. The entire hot tub should fit with room to spare.
⚠️ Safety Equipment Required
When cutting the hot tub shell, wear safety glasses, a dust mask (N95 or better), long sleeves, and work gloves. Fiberglass particles from the shell and insulation are irritating to skin, eyes, and lungs.
What Can and Can't Go in the Dumpster
✅ Accepted Materials
- Acrylic/fiberglass shell - The main tub body
- Wood frame and cabinet - Treated or untreated lumber
- Foam insulation - The spray foam around the shell
- PVC plumbing - Pipes and fittings
- Pumps and heaters - Most companies accept these
- Cover and accessories - Spa cover, steps, handrails
❌ Not Accepted (Dispose Separately)
- Chemicals - Chlorine, bromine, pH balancers (hazardous waste)
- Electronics - Digital control panels may need e-waste recycling
- Refrigerant - If your spa has a chiller (rare), refrigerant must be professionally reclaimed
Tips for Easier Hot Tub Removal
- Work with a helper. Shell pieces are awkward, and having someone to help lift makes the job safer and faster.
- Use a sawzall with fresh blades. You'll dull at least 2-3 demolition blades cutting through fiberglass. Have extras ready.
- Cut strategically. Cut the seat sections first—they're thicker. Cut along seams where possible.
- Let it dry first. Wait 24-48 hours after draining for residual water to evaporate. Wet foam is heavier.
- Consider the access path. Make sure your dumpster placement allows you to easily carry pieces from the hot tub location.
- Check for salvage value. Working pumps, heaters, and jets can be sold online to hot tub DIYers.
💡 Time Estimate
Most DIY hot tub removals take 4-8 hours for one person, or 2-4 hours with a helper. Plan for a full day if it's your first time.
Frequently Asked Questions
Can I put a whole hot tub in a dumpster?
No. Hot tubs are too large and heavy to dispose of whole. They must be cut into pieces. Even if the tub would physically fit, the weight concentrated in one area could damage the dumpster or exceed weight limits.
How heavy is an empty hot tub?
An empty hot tub typically weighs 500-900 pounds depending on size and construction. Older acrylic models with heavy wood frames are on the heavier end. Lightweight rotomolded (plastic) tubs may weigh only 300-400 pounds.
Can I recycle a hot tub?
Partially. The acrylic shell can sometimes be recycled at specialized facilities, though this isn't common. The wood frame, copper wiring, and metal components (pumps, heaters) can be recycled through scrap metal facilities. Most of the hot tub will go to landfill.
What if my hot tub is still working?
Consider selling or donating it first. Working hot tubs have value. List it on Facebook Marketplace, Craigslist, or offer it to a hot tub refurbisher. Some charities accept working spas. Moving a hot tub typically requires a crane or several strong helpers.
Do I need a permit to dispose of a hot tub?
Typically no. Hot tub removal doesn't require permits in most areas. However, if you're placing a dumpster on the street (not your driveway), you may need a street permit. Check with your local municipality.
