Generic 4 to 6 person: 150 jets, cover, 2 filters

What comes in the box, according to the seller

The listing describes a complete spa set. There is an integrated air pump that inflates the tub from the control panel, so you do not need a separate hose or a foot pump. A filtration unit with two cartridges is included, and the bullets mention an insulated cover that is meant to reduce heat loss between soaks.

Six colour LED lighting and a 72 hour automatic shut-off are also listed. The shut-off means the heater stops after three days of continuous running, which is worth knowing if you like to keep the water hot all week: you will need to restart it from the panel.

Size, jets and heating in plain terms

The title gives 81 by 28 inches, which works out at roughly 206 cm across and 71 cm high. That is a common family size, a little wider than a 196 cm Lay-Z-Spa. Be aware that the part number on the listing refers to 72 by 28 inches, so the seller may be using one page for two sizes. Ask which one ships before you clear space on the patio.

Bubbles come from 150 air jets in the title, while a bullet says 150 to 180, with three intensity levels. The temperature can be set between 20 and 40 °C. The heater's wattage is not given, so there is no way to estimate how long the first fill will take to warm up or how much it will add to your electricity bill.

Living with it: filters and upkeep

Two filter cartridges sit in the filtration system, and the listing mentions hard water care. What it does not say is the cartridge type or size. With an unbranded tub, that matters more than anything else: if you cannot match the filter, you will struggle to keep the water clear over a season. Check whether the seller sells spares, or whether a common cartridge fits, before you commit.

The walls are described as a brushed, puncture resistant material rather than plain PVC. There is no stated wall thickness or drop-stitch construction, so treat it as a standard inflatable and use a ground mat on any rough surface.

Against the BANGBANGJI and LADECNERHT tubs

The BANGBANGJI 206 cm tub is the same diameter but states a 1,400 W heater and drop-stitch walls, which gives you far more to go on. The LADECNERHT 180 cm tub is smaller, for three or four people, and adds a drainage function. This generic model sits between them: bigger than the LADECNERHT, but with less detail than the BANGBANGJI.
