What is the depreciation period for a hot tub at an Airbnb?

A freestanding or portable hot tub used in a short-term rental is generally classified as 7-year MACRS personal property under IRC §168. It qualifies for 100% bonus depreciation in 2026, allowing you to deduct the full cost in the year it is placed in service. If the hot tub is permanently built into a deck or concrete pad (truly a structural fixture), it may be treated as a 15-year land improvement or 27.5-year structural component.

Can I deduct the installation cost of a hot tub for my STR?

Yes. Installation costs — electrical hookup, plumbing, deck reinforcement required for the hot tub — are capitalized and depreciated as part of the hot tub's total cost basis. They are not separately deductible as a current expense. If the deck reinforcement would have value independent of the hot tub, it may be treated as a separate 15-year land improvement.

Is the maintenance cost for a hot tub deductible separately from depreciation?

Yes. Ongoing maintenance and operating costs for your STR hot tub are fully deductible as current business expenses in the year paid — separate from the depreciation on the hot tub unit itself. This includes chemicals, filter replacements, service calls, water heating costs, and repairs that don't constitute capital improvements.

What happens if my hot tub is permanently installed and can't be moved?

If a hot tub is so permanently attached to the structure that it cannot be removed without damage (for example, fully built into a deck with framing around it, plumbed into the building's permanent water supply), it may be reclassified as a structural component of the building (27.5-year) or as a 15-year land improvement. A freestanding plug-in hot tub, even if heavy, is generally still treated as 7-year personal property.

How to Depreciate a Hot Tub for Your Airbnb

A freestanding hot tub installed at your short-term rental is classified as 7-year MACRS personal property under IRC §168—not a structural building component. This means it qualifies for 100% bonus depreciation in 2026, allowing you to deduct the full purchase price plus installation costs in the year it is placed in service.

Why 7-Year, Not 5-Year or 27.5-Year?

Hot tubs occupy an interesting middle ground in the MACRS classification system. They are not appliances (which are 5-year property under asset class 00.12), and they are not structural components of the building (27.5-year property). Hot tubs are classified as 7-year personal property under the "catch-all" class for property that doesn't fit neatly into another specific asset class under Rev Proc 87-56.

The practical difference between 5-year and 7-year MACRS is minimal in practice for STR operators with access to 100% bonus depreciation: both allow full deduction in Year 1 when bonus depreciation is elected. The classification matters primarily if you are using standard MACRS without bonus depreciation.

Real Dollar Example

You purchase and install a hot tub at your STR cabin in June 2026. Total cost: hot tub unit $8,500, electrical hookup $1,800, delivery and crane placement $950, cover and steps $600 = $11,850 total basis. With 100% bonus depreciation, you deduct the full $11,850 in 2026. At a 30% combined tax rate, that's $3,555 in immediate tax savings.

What's Included in the Depreciable Basis

The hot tub's depreciable basis includes not just the purchase price of the unit itself, but all costs required to place it in service in your rental. This is an important point that many STR operators miss.

Hot Tub Basis: What to Include

7-Year MACRS · 100% Bonus

All of the following are part of the hot tub's depreciable basis:

Hot tub unit purchase price: Include all costs on the purchase invoice
Delivery and placement: Freight, crane rental if needed
Electrical connection: Running dedicated circuit, GFCI outlet, sub-panel if required
Plumbing: If dedicated water supply/drain installed specifically for the hot tub
Cover and cover lifter: Part of the unit's operational equipment
Steps/stairs: Required for access, part of the installation
Initial water treatment: Generally a current expense, not capitalized

The Structural vs. Portable Distinction

The 7-year personal property classification generally applies to hot tubs that can be physically removed from the property without structural damage. The test is removability without substantial structural modification.

Hot Tub Configuration	Classification	Recovery Period	Bonus Eligible?
Freestanding plug-in (120V or 240V)	Personal property	7 years	Yes (100%)
Placed on deck, electrical only	Personal property	7 years	Yes (100%)
Built into deck framing, removable	Personal property	7 years	Yes (100%)
Fully integrated, structural surround built around it	Land improvement or structural	15–27.5 years	15-yr: Yes; 27.5-yr: No
In-ground spa (gunite, attached to pool)	Structural component	27.5 years	No

The vast majority of above-ground hot tubs used in STRs—even those sitting on reinforced decks with permanent electrical connections—are treated as 7-year personal property because they can be physically moved and relocated if desired.

Ongoing Maintenance: Separately Deductible

The depreciation deduction covers the capital cost of the hot tub itself. All ongoing maintenance and operating costs are separately deductible as current business expenses in the year incurred. These are not capitalized and do not affect your depreciation schedule:

Chemicals (chlorine, pH balancers, shock treatments)
Filter replacements and cartridges
Service and repair calls (jets, pumps, heater elements)
Water testing supplies
Cover replacement (if due to wear, not an upgrade)
Electricity costs for heating and pumps (included in utility deductions)

Maintenance Documentation

Keep a simple log of your hot tub maintenance costs by date. Many STR operators find hot tub maintenance runs $600–$1,500 per year in chemicals, filters, and service. Over five years of ownership, that's $3,000–$7,500 in additional deductions beyond the original depreciation. Track these costs separately from capital improvements.

Section 179 as an Alternative to Bonus Depreciation

If you prefer to use Section 179 instead of bonus depreciation, a hot tub qualifies as Section 179 eligible property. The result in 2026 is the same: 100% of cost deducted in Year 1. Section 179 has the limitation that it cannot create a net loss from the rental activity, so if your STR is showing a loss before the hot tub deduction, bonus depreciation is the better choice (it can deepen the loss, which may offset other income under the STR active participation rules).

For a full comparison of Section 179 and bonus depreciation for STR personal property, see our guide to Section 179 for STR furniture and appliances.

Mixed-Use Consideration

If you use your STR personally for any portion of the year, the hot tub deduction must be prorated by the business-use percentage. Track your personal days vs. rental days carefully. Personal use of an STR for more than 14 days (or 10% of rental days) triggers the "vacation home" rules, which can limit your deductions significantly.
