Best Hot Tub Accessories (2026): Steps, Filters, and Pillows

An inflatable hot tub becomes much easier to live with once three small things are in place. You need a safe way in and out, a steady supply of clean filters, and something to rest your head on during a long soak. Those are the accessories that change how often you actually use the tub.

This guide sits in the hot tub and spa section. If you are still choosing the spa itself, start with the best inflatable hot tub for cold weather and come back here once the tub is on the deck.

What separates a useful hot tub accessory from clutter

Inflatable spas are simple machines, and most accessories only matter when they solve one of four problems: safe entry, clean water, comfortable soaking, or cold-weather heat loss.

The best purchases touch the tub every session. Steps get used twice a soak. Filters run the whole time the pump is on. A headrest matters the moment you stop bobbing and lean back. Snow shovels, cup holders, and floating lights are fun, but they sit in a bin after a week.

A second filter or two belongs on the shelf before you need it. Pumps lose flow as a cartridge loads, and a slow pump is the most common reason an inflatable spa throws a low-flow error on a warm evening.

Best overall: Dovov Hot Tub Steps with Storage

The Dovov 36.6" Hot Tub Steps with Storage is the accessory we would add first. It gives you a wide, textured platform to sit on and swing your legs into the water, which is much safer than stepping over a wet inflatable wall. The 36.6-inch width fits a standard spa entry without crowding the deck.

The part that keeps it on the deck is storage. Two sealed compartments hold about 22.5 gallons up top and 10.4 gallons below, which is enough for folded towels, a test kit, and a spare filter. The lower bin is a good home for anything you want out of the weather.

It is rated to 780 pounds but weighs only about 16.5 pounds, so one person can move it when the spa gets repositioned. The snap assembly means no screws to rust or strip. Prices on this one move around, so if it is discounted when you look, that is a fair moment to buy.

Buy it if your spa sits on a deck or patio and you want a safer entry with storage built in. Skip it if your tub is set low to the ground and you already step in without trouble.

Best water care: Macaberry Type VI Filter 12-Pack

The Macaberry Type VI Hot Tub Spa Filter Replacement pack is the accessory you will rebuy all season, so buy it in bulk. These cartridges fit the Type VI pumps used in Coleman SaluSpa and Lay-Z-Spa inflatables, and the 12-pack covers a full season of swaps at roughly two weeks each.

A clean cartridge is the difference between clear water and a cloudy tub. When the filter loads up, the pump pulls less water, the heater works harder, and chemistry gets harder to hold. Owners who switched from worn factory filters report the water clearing and pH settling down within a few days.

Treat the filters as consumables. Rinse them every few days, swap in a fresh one every two to three weeks with regular use, and keep a clean spare on the shelf. Rotating two cartridges is the habit that keeps an inflatable spa from throwing a low-flow error on the night you wanted to soak.

Buy it if you run a SaluSpa or Lay-Z-Spa and want a season of filters on hand. Skip it if your spa uses a different cartridge, and check the housing first.

Best comfort: HUGABOW 2-Pack Large Hot Tub Pillow

The HUGABOW 2-Pack Large Pillow for Hot Tub is the small upgrade that makes a 20-minute soak a 40-minute one. The pillow measures about 13.5 by 9 inches and uses a weighted strap to hold it against the spa wall at the height you choose. On an inflatable shell that flexes under your weight, a strap beats suction cups.

The 4D air mesh cover is built to shed water instead of soaking it, so the pillow dries between sessions rather than sitting damp in a storage bin. The two-pack means two seats get support, and the neutral gray works with most spa colors.

The honest caveat is size. It is a large pillow for a standard seat, not an oversized one. If you have a wide bench or you like a lot of padding, look at your seat width before ordering.

Buy it if you lean back and read or soak for long stretches. Skip it if you never sit still, and skip the second pillow if you usually soak alone.

How to keep an inflatable spa in shape

The accessories only pay off if the basics stay ahead of them.

Rinse the filter every few days. A quick rinse under the tap keeps flow up and stretches each cartridge. Keep a spare clean and dry.

Keep the cover on between soaks. The cover holds heat, keeps debris out, and lets the heater recover faster. On a cold night it is the difference between a warm tub and a long wait.

Dry the storage bins. The sealed step compartments keep towels dry in rain, but leave them open for an hour after a wet day so moisture does not linger.

Set it on a flat, solid surface. A full tub is heavy. An uneven base rocks the shell, stresses the seams, and makes the steps feel unstable.

Watch the water, not just the calendar. Filters, covers, and steps all work better with balanced water. A simple test kit tells you when to adjust instead of guessing.

When to skip the extras

Not every accessory is worth the deck space. Cup holders, floating lights, and beverage floats are fun for a party and easy to forget after. Snow and ice tools matter only if your tub stays out in a hard freeze, and most makers recommend draining an inflatable spa below about 20 degrees Fahrenheit anyway.

Skip the steps if your spa is set low and entry is already easy. Skip the bulk filter pack if you use your tub rarely, because a season's worth will outlast the water changes. Skip the second pillow if you soak alone.

On a permanent spa with a hard cabinet, a hot tub cover lifter is the next upgrade after the steps. It folds the cover back with one hand and keeps it off the deck grit. Most lifters are built for square or rectangular tubs, so an inflatable usually needs a cover strap instead.

Bottom line

For most inflatable hot tub owners, the Dovov 36.6" Hot Tub Steps with Storage is the best first accessory, with safe entry and dry storage in one piece. Add the Macaberry Type VI Filter 12-Pack so clear water never waits on a spare, and finish with the HUGABOW 2-Pack Pillow for longer, easier soaks. Buy them in that order and the tub gets used more, not less.
