Your new hot tub arrives with a cover and a control panel. Within a week, most owners realize they need a few more things: a safe way in and out, a way to test the water, somewhere to put towels. Some accessories are essential from day one. Others make the tub nicer to use but can wait.
Here’s a practical list, split into must-haves and nice-to-haves, with what to look for in each.
Quick checklist
| Accessory | Priority | Why you need it |
|---|---|---|
| Steps | Must-have | Safe entry and exit |
| Water test strips or kit | Must-have | Safe, balanced water |
| Spare filter cartridge | Must-have | Swap while the other dries |
| Filter cleaner | Must-have | Longer filter life |
| Basic chemicals | Must-have | Sanitize and balance |
| Cover care | Must-have | Protect your biggest heat saver |
| Clarifier | Recommended | Fix cloudy water fast |
| Towel rack | Recommended | Dry towels, tidy deck |
| Cover cap | Recommended | Protect the cover from sun |
| Shade or gazebo | Nice to have | Year-round comfort |
| Smart water monitor | Nice to have | Daily automatic testing |
| Waterproof speaker | Nice to have | Music in the tub |

The must-haves
1. Hot tub steps
Climbing over a 35-inch spa wall with wet feet is the most common way owners slip. A sturdy, non-slip step is the first accessory to buy. Look for wide treads, a non-slip surface and a height that matches your tub. Some steps include storage for chemicals and test kits, such as these hot tub steps with storage or the 2-step spa stairs with storage. For taller spas or less steady users, choose a model with handrails like these wooden steps with handrails or a 4-step ladder with handrail.
2. Water testing
You should test your water two or three times a week. Test strips are fastest: dip, wait and match the colors. These 7-in-1 test strips check chlorine or bromine, pH, alkalinity and hardness. A liquid kit, such as these 5-way test kit refills, is more precise. Our hot tub water maintenance guide explains the target ranges.
3. A spare filter cartridge
Keep two filters and rotate them. While one is in the tub, the other is cleaned and drying. It doubles filter life and avoids downtime. Make sure the cartridge matches your spa, for example the PRB25-IN compatible filters or this Unicel C-4326 fit filter. See how to change a hot tub filter.
4. Filter cleaner
A monthly soak in filter cleaner removes oils and scale that a hose can’t. It keeps flow strong and prevents flow error codes.
5. Basic water chemicals
You need a sanitizer (chlorine or bromine), pH up and pH down, an alkalinity increaser and shock. Our beginner’s guide to hot tub chemicals explains each one, and how often to shock your hot tub covers the routine.
6. Cover care
Your cover saves more energy than any other part of the spa. Clean and condition the vinyl every few months, and lock the straps in windy weather. When it’s time to replace it, read our cover replacement guide and measure carefully. Options include this rectangular cover and octagon cover.
The recommended extras
7. Clarifier
Clarifier clumps tiny particles together so the filter can catch them, clearing cloudy water quickly. Try a concentrated one like this 16 oz spa clarifier, or a larger bottle such as this 128 oz clarifier. If water is cloudy after shocking, see cloudy hot tub water after shock.
8. Towel rack
A freestanding rack keeps towels dry and within reach. Choose a weighted base so it doesn’t blow over: this freestanding towel rack with basket, a 5 ft outdoor towel stand or a rattan towel valet with shelves.
9. Cover cap
A fitted cap over your hard cover shields the vinyl from UV, rain and bird droppings, so the cover lasts longer. See the 86 in square cover cap and 84 in round cover cap.
The nice-to-haves
10. Shade and shelter
A gazebo or pergola keeps sun off the water in summer and snow off the cover in winter. It also adds privacy. Options include a 10×12 hardtop gazebo, a 10×10 aluminum pergola and a wall-mounted gazebo.
11. Smart water monitor
A floating smart monitor tests your water daily and sends results to your phone. This Wi-Fi water monitor is a good fit for owners who travel or forget to test.
12. Waterproof speaker
Many larger AquaLife models include Bluetooth audio. If yours doesn’t, a floating waterproof speaker does the job. See how to add music to your hot tub.
