4 person hot tubs
How much space a 4 seater hot tub needs
The 3 four-seater outdoor hot tubs range from 160 to 190 cm in width, and that is the difference that matters most when choosing. The Hot tub BL-839 fits into a square of 160 × 160 cm: it is the most compact in the range for this capacity, and on a terrace or in a narrow courtyard it is often the only one that actually fits. The Hot tub BL-828 needs 190 × 190 cm, while the Hot tub BL-881 measures 200 × 160 cm and is the only rectangular model of the group, useful where the space runs lengthwise along a wall or a hedge. For comparison, a six-seater outdoor hot tub starts at 200 cm per side and reaches 245, which is at least 56% more surface area. Allow 50-60 cm of service space on every accessible side, needed for filter maintenance and access to the equipment bay.
How much a hot tub weighs when full
This is the figure to check before anything else if the installation is on a terrace, a floor slab or a raised deck. Empty, the Hot tub BL-839 weighs 250 kg, the Hot tub BL-881 310 kg and the Hot tub BL-828 387 kg. With water the picture changes completely, because every litre adds a kilo: from around one tonne for the lightest to over one and a half tonnes for the largest, and the weight of the bathers has to be added on top. These are indicative figures, useful to establish the order of magnitude: installation on a floor slab always requires a survey by a structural engineer to assess the actual load-bearing capacity. On the ground, over a concrete base, the question does not arise.
Indoor or outdoor, and how it is positioned
All four-seater hot tubs are suitable for both outdoor and indoor use. The Hot tub BL-828 and the Hot tub BL-839 can be installed above ground, partially recessed or fully recessed; the Hot tub BL-881 is specified above ground only, which is the difference to keep in mind if the project calls for a recessed installation. Installation requires a level base, a water drain nearby and an electrical supply: single-phase 220/240 V as standard, with three-phase 380 V available on request. The tub arrives as a single unit, already tested: there is no on-site assembly.
What actually separates the models
Price follows the hydromassage, not the size. The Hot tub BL-839 is the smallest and at the same time the most expensive, because it carries 53 jets: almost twice as many as the Hot tub BL-828, which has 29 despite being larger. At the opposite end the Hot tub BL-881 has 17, spread across the largest water volume of the group, and is built for wide immersion rather than intense massage. Anyone after the strongest massage in the smallest footprint looks at the Hot tub BL-839; anyone after the largest tub, the Hot tub BL-881; anyone looking for balance, the Hot tub BL-828. All of them carry Balboa Systems® electronics made in USA, an Aristech® acrylic shell on a self-supporting frame, chromotherapy, a Bluetooth audio system and an ozone steriliser as standard.
Frequently asked questions about 4 seater hot tubs
Is the water heated? Can it be used in winter? Yes. The Balboa heater brings the water up to 39 °C and holds the set temperature all year round, even outdoors in cold weather. The thermal cover, available among the accessories, substantially reduces consumption when the tub is not in use.
Can it be installed indoors? Yes, all models are specified as suitable for indoor use. You need a room with a floor drain, adequate ventilation to handle humidity and a floor verified for the full-tub weight given above.
Why does a 4 seater hot tub cost as much as a 6 seater? Because the price depends on the hydromassage specification and the materials, not on the number of seats. A compact tub with over fifty jets, three pumps and complete electronics costs more than a larger tub with a basic specification. If available space is the priority, the four-seater remains the right choice even at the same outlay.
How much does a 4 person outdoor hot tub cost? The models in the range run from € 6.725 to € 7.125. The price covers the complete tub with Balboa electronics, chromotherapy, Bluetooth audio and ozone steriliser; shipping is quoted separately, as it is handled by a specialist carrier.
Are these rigid or inflatable tubs? Rigid. The shell is Aristech® acrylic made in USA on a self-supporting frame, with a PVC exterior. It is not an inflatable product and it is not dismantled seasonally.
