A built in hot tub is set into a deck, patio or floor, while a freestanding hot tub stands on its own rather than being installed into its surroundings. The built in vs freestanding hot tub choice comes down to space, permanence and installation: a built in tub suits a fixed outdoor room, while a freestanding inflatable tub suits a renter, a small yard or a buyer who wants to move it later. The tubs featured below are all freestanding inflatable models, so they show the freestanding side of the choice in detail.
This guide sets out how the types differ on installation, space, power and upkeep, then looks at the freestanding inflatable tubs below. Listings were collected 4 November 2026.

The built in vs freestanding hot tub decision
A built in tub becomes part of its surroundings: it is installed into a deck, patio or floor and stays there, which suits a permanent outdoor room planned around soaking. A freestanding inflatable tub stands on a flat surface, needs no construction around it, and can be drained, deflated and moved when plans change. A built in spa circuit should be installed by a licensed electrician.
Upkeep differs in the same direction. A built in tub is plumbed and wired in place, so filter and water care happen at a fixed station. The freestanding inflatables below carry their heating equipment in the unit itself, with different combinations around it: heater pumps on the SunSwell and RELXTIME listings, removable filtration on the SunSwell and RELXTIME listings, and covers on the SunSwell and Intex listings.
Space, power and upkeep side by side
| Type | Installation | Moves later | Examples below |
|---|---|---|---|
| Built in | Set into a deck, patio or floor | Stays in place | None featured below |
| Freestanding | Stands on a flat surface | Portable inflatable models | The tubs below |
Power needs a check before buying. The SunSwell listing states GFCI protection, which is the safety device to look for on any tub outlet. The listings here do not state voltage or plug type, so check the listing for plug type before buying.
Freestanding tubs worth a look
| Product | Chill Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| SunSwell 71in Spa | 9.6 | 29 | 20 | 21 | 7 | 0 |
| Intex PureSpa Chevron | 9.4 | 28 | 20 | 21 | 0 | 0 |
| RELXTIME Spa Tub | 9.4 | 29 | 19 | 20 | 0 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
Check Your Space First
- Measure the flat area: the tubs below measure 71.0 x 71.0 x 25.6 inches, 69 x 69 x 28 inches and 73.0 x 73.0 x 25.6 inches.
- Plan a ground mat: the RELXTIME listing recommends a thick ground mat underneath for insulation, and notes it is not included.
- Check the outlet: the SunSwell listing states GFCI protection.
- Plan storage for extras: the SunSwell steps include a storage compartment for spa supplies.
Common questions
Can a freestanding hot tub move with you?
Yes, when it is an inflatable model. The Intex listing describes FastFill inflation and deflation at the touch of a button with no external hose, and the SunSwell and RELXTIME listings describe lightweight, portable builds. A built in tub is not made to move, since it is installed into its surroundings.
Does a built in hot tub need construction work?
A built in tub is installed into a deck, patio or floor, so it involves building work that a freestanding tub avoids. A freestanding tub stands on a flat surface and needs no construction around it. The trade is permanence: the built in tub stays, while a freestanding inflatable tub can be moved.
How many people do these freestanding tubs seat?
The SunSwell seats 4 to 6 people, the Intex seats 4 people, and the RELXTIME seats 4-6 people. Check the stated seat count against the household, since the listings give no weight limit for bathers. The SunSwell steps alone are rated to 661 lbs.
What safety features do the featured tubs list?
The SunSwell listing states GFCI protection and an insulated cover with a child-safety lock. The Intex listing states a PTC heater and an energy efficient cover. The RELXTIME listing states a filtration system that shows an FC error code when the filter loses effectiveness.
