2–3 Person Black Inflatable Square Hot Tub with 110 Jets

Some days, you just need to switch off. The RELXTIME 2–3 Person Black Square Inflatable Hot Tub is built for exactly that. Whether it’s a Friday night after a long week, a Sunday morning with a coffee in hand, or a cool fall evening when the air is crisp and the water is 104°F — this portable spa turns any outdoor space into the kind of retreat you actually look forward to. Setup takes minutes. No contractor, no concrete pad, no five-figure installation bill. Just inflate, fill, heat, and get in.

110 Bubble Jets That Actually Do the Work

The RELXTIME square inflatable hot tub runs 110 air bubble jets that push warm, aerated water all around you. It’s a gentle, full-body effect — the kind that loosens tight shoulders and tired legs without being aggressive. These are air jets, not directional HydroJets, so the massage is soft and enveloping rather than targeted at one spot. If you’re after deep-tissue pressure, a HydroJet model would be the step up. But for pure relaxation and stress relief after a long day? The bubble jet experience here gets the job done.

Built Tough for Canadian Conditions

Canada’s climate isn’t easy on outdoor products. RELXTIME knows that. The walls on this tub are made from laminated PVC with vertical I-beam construction running through them — it’s the same internal beam approach that keeps the walls rigid under water pressure, resisting both punctures and stretching over time. This isn’t a flimsy blow-up pool. The square shape also holds its structure better than round tubs tend to, and the black finish absorbs heat from the sun to help maintain water temperature on warmer days.

The freeze protection feature is worth calling out separately. When outdoor temps drop toward freezing, the automatic freeze guard kicks in and keeps the pump and internal components from damage. That means you can use this tub well into fall — and in milder Canadian winters, too — without worrying about cracking a pump housing overnight.

Setup, Maintenance & What’s in the Box

Getting started is straightforward. Inflate the tub using the built-in pump, connect your garden hose, and let the heater bring the water up to your target temperature. From cold tap water, expect roughly 1–2 hours to reach 104°F — worth planning around, especially on cooler days.

Day-to-day upkeep is easy:

• Rinse the filter cartridge every 1–2 days during regular use
• Replace the filter cartridge every 1–2 weeks (two are included to get you started)
• Use standard chlorine or bromine for water care
• Place a sponge mat underneath the tub for extra insulation from the ground (not included, but recommended)

What comes in the box?

• RELXTIME inflatable square hot tub
• Built-in heater and pump unit
• Insulated cover with cover clips
• 2 filter cartridges
• Cup holder
• Repair patch kit
• Digital control panel

Who This Tub Is For?

The RELXTIME 2–3 person square hot tub is a strong pick for couples who want a personal spa without the commitment of a permanent installation. It’s also a great choice for renters, condo owners with a balcony or patio, or anyone buying their first inflatable spa who wants to try the experience before going bigger. The square footprint fits into tighter outdoor spaces better than round tubs, and when summer ends, it deflates and stores flat until you need it again.
