What are the Most Popular Hot Tub Shapes?


Hot tubs come in various shapes, but some are more popular than others.


Circular hot tubs

A square hot tub was the traditional shape, but more people are switching from these traditional hot tubs to circular ones nowadays. They are more portable than other shapes and comparatively cheap and space-saving.

They have a small footprint, so you can fit one almost anywhere. They are built for one to two people.


Triangular hot tubs


This is not one of the most common shapes, but if you're short on space or want a hot tub that looks a little more unique, it's a good option. It has good visual appeal, but the shape is very limiting.


Square hot tubs

Square hot tubs are the most traditional shape. One of the advantages of a square shape is the space delineation, which is a plus when there are lots of people in the tub. They also fit neatly against a deck, porch, or side of the house. When installed, they also look more natural than other shapes.


Rectangular hot tubs


With a rectangular hot tub, you've got more room to stretch out, which is especially useful if you're a tall person who wants to relax. Much like a square tub, it can be positioned almost anywhere without getting in the way.

FAQs


What type of hot tub is best?


The answer to this question depends on your needs. If your budget is limited, an inflatable model might be the perfect tub for you. If you want to use your hot tub daily, you want something that's durable. Before deciding what type is best for you, consider how you plan to use your hot tub.


What type of hot tub is the cheapest?


The cheapest hot tubs are inflatable ones.


What type of hot tub is easiest to maintain?


Most hot tubs require daily maintenance; however, tubs in an outdoor space need to be cleaned more than indoor tubs. Hot tubs must also be drained regularly and deep cleaned every few months. This prevents the water from becoming unsanitary and allows you to clean the hot tub components thoroughly.

A well-maintained and well-built hot tub will last between 15 and 25 years. Cheaper hot tubs, such as portable and inflatable types tend to last just a few years.
