Inflatable Hot Tub Accessories: 15 Must-Have Add-Ons

Essential Accessories (Get These First)

1. Insulated Ground Mat

The ground beneath your hot tub is the single biggest source of heat loss. An insulated ground mat or foam pad creates a thermal barrier that reduces heating costs by 15-20% on its own. It also protects the bottom of your tub from punctures and debris.

• Best option: Closed-cell foam mat (1/2" thick minimum)
• Budget option: Interlocking foam floor tiles from any hardware store
• Cost: $20-$50

2. Thermal Floating Blanket

A thermal floating blanket sits on the water surface underneath your cover, adding an extra insulation layer that prevents heat from escaping through evaporation. This is the single best energy-saving accessory - it can reduce heating time by 30% and lower monthly energy costs by $10-$25.

• Type: Circular solar/thermal blanket sized to your tub diameter
• Cost: $15-$35

3. Replacement Filter Cartridges

Filters should be replaced every 2-4 weeks with regular use. Stock up on a multi-pack to avoid running out. Make sure to buy the correct size for your model - Coleman/SaluSpa and Intex use different filter types.

• Coleman/SaluSpa: Type VI filter cartridges
• Intex: Type S1 filter cartridges
• Cost: $15-$30 for a 6-pack

4. Water Chemistry Kit

Every inflatable hot tub owner needs a basic chemical kit. See our complete chemicals guide for details. At minimum you need:

• Chlorine granules or bromine tablets (sanitizer)
• pH increaser and decreaser
• Non-chlorine shock oxidizer
• Test strips (50-count minimum)
• Cost: $30-$50 for a starter kit

5. Floating Thermometer

While your hot tub has a built-in temperature display, a floating thermometer gives you an instant visual check without accessing the control panel. Useful for verifying accuracy and checking temperature before getting in.

• Cost: $5-$12

Comfort Upgrades

6. Drink Holders / Tray

Inflatable hot tubs don't have built-in cup holders. A clip-on or floating drink holder keeps beverages at hand without risking spills into the water. Options range from simple floating trays to clip-on caddies that attach to the tub wall.

• Cost: $10-$25

7. Inflatable Headrest / Pillow

A waterproof headrest or pillow makes extended soaks significantly more comfortable. Look for suction-cup models that attach to the inner wall for stability.

• Cost: $10-$20

8. Entry Steps

Inflatable hot tubs sit 26-28 inches off the ground. While you can step over the wall, a set of non-slip entry steps makes getting in and out safer and more comfortable - especially for older users or anyone with mobility concerns.

• Cost: $30-$60

9. LED Lights

Waterproof LED lights transform your nighttime soaking experience. Submersible color-changing LED lights create a spa-like ambiance that makes every evening soak feel luxurious. Some SaluSpa models come with built-in LED lights, but add-on options work with any tub.

• Cost: $15-$40

Protection & Maintenance Accessories

10. Upgraded Cover

The included cover is usually inflatable with minimal insulation. Upgrading to a higher-quality insulated cover with locking clips reduces heat loss and keeps debris out more effectively.

• Cost: $40-$80

11. Cover Lifter / Holder

A simple rack or hook system to hold the cover when removed prevents it from getting dirty on the ground and makes covering/uncovering the tub easier.

• Cost: $20-$40

12. Skimmer Net

A small handheld skimmer net lets you quickly remove leaves, bugs, and debris from the water surface before or after each use. Essential if your hot tub is outdoors near trees.

• Cost: $5-$10

13. Drain Pump

The built-in drain valve works but is slow. A small submersible pump ($20-$30) drains your tub in 15-20 minutes instead of hours, making regular cleaning much less tedious.

• Cost: $20-$30

14. Repair Patch Kit

Most inflatable hot tubs include a small repair patch, but having a proper PVC repair kit on hand means you can fix small punctures immediately without waiting for a replacement. Waterproof patch kits work on both above and below the waterline.

• Cost: $8-$15

15. Privacy Screen / Wind Barrier

A privacy screen serves double duty: it blocks wind (which is the #2 cause of heat loss after evaporation) and provides privacy for outdoor soaking. Bamboo screens, outdoor curtains, or purpose-built wind barriers all work well.

• Cost: $30-$100+ depending on style

Total Budget for Essential + Comfort Accessories

You don't need everything at once. Start with the essentials (ground mat, blanket, chemicals, filters) and add comfort and protection items over time.
