There are several factors you must consider if you are planning to purchase a hot tub:

#1 Seating Capacity

The question of “how many seats do I need for my hot tub?” is undoubtedly your main concern. Knowing how many people you need to accommodate is the first factor to think about before buying!

Choose small spas if you want two or three people to join in your hot tub. A two or three-seater is ideal for couples who want to have a romantic date night at the convenience of their home.

Also, two-person hot tubs are energy-saving because they only need one heat pump.

On the other hand, you can opt for a four-person hot tub model if you have a large friend group.

A four-person model is trendy on the market because it accommodates everyone and is energy-saving. A 4-person hot tub needs at least 50 to 60 jets, equating to 20 jets per person.

Finally, 6-8 person hot tubs are for you if you need to accommodate even bigger groups of family and friends.

#2 Shape

A hot tub spa comes in different forms and shapes. You can opt for a square, rectangular, round/circular, or triangle.

We suggest choosing the rectangular shape if you want more entry and exit points.

#3 Material

An important factor to consider when choosing the best hot tub spa is the material. Your hot tub model must have a STURDY foundation.

This ensures that the filled water and the people inside the hot tub can be supported.

We suggest purchasing a hot tub made with acrylic shells, as they can support the shape, the seat, and the people inside the tub regardless of weight.

#4 Installation

No one wants a hot tub that’s hard to install.

With this, your hot tubs must have convenient installation technology so you won’t have difficulty installing it or require much assistance.
