What size pool with hot tub should I choose?

When determining the right size of pool with hot tub for your backyard, consider the available amount of space. For instance, if you have a relatively small backyard, opt for a pool with smaller standard dimensions of 20’ x 10’. If you have plenty of room in your yard, go for a model with larger dimensions of 33’ x 13’ or 33’ x 20’.

Larger, deeper pools are more expensive to install and run, as you’ll need to spend more money on heating and sanitation. Think about your budget before making your final decision on the size of your pool.

You should also think about how large you want your hot tub to be in relation to the pool. Small hot tubs tend to measure 3’ -5’ deep by 4’-6’ across, while larger models have a diameter of between 6’ - 8’ and a depth of 4’- 6’.

You also need to consider how many people can use the pool and hot tub. A small hot tub can comfortably accommodate 2-4 people, while a larger tub can fit up to 8 people, ideal for entertaining friends and family.

What shape is best for a pool with hot tub?

The best shape for a pool with hot tub is subjective and depends on the amount of yard space you have available and your patio space style. There are tons of designs for a pool and hot tub combination available, but two are extremely popular and will work well in most yards.

For a casual, fun pool and hot tub area where people can enjoy backyard barbecues and mingle freely, consider a kidney shape pool with an adjacent circular hot tub. This layout appears fluid and connects the hot tub and pool areas effortlessly so that no matter which body of water you're enjoying, you can still socialize with everyone. The curving edges of these pools are also pleasing to the human eye.

For the serious swimmer planning to use the pool in a primarily private context, opt for a rectangular pool and built-in, raised square hot tub. This layout makes it convenient to swim laps each morning in the pool and then do some polar plunge-style switches between the hot tub and pool afterward.

How much water do you need to fill a pool with a hot tub?

The amount of water you need to fill a pool with a hot tub depends on the size of the model. For 1 ft³ you need 7.48 gallons of water. To find the exact volume of water for your specific pool with a hot tub, you need to measure the width, height and depth of the interior of the tub.

For example, a pool measuring 4’x6’x6’ equals 144 ft³. 144 x 7.48 gallons means you’ll need exactly 1,077.19 gallons to fill the pool.

If you have an irregularly shaped pool, such as an L-shaped pool, you would split the L-shape into two separate boxes and measure the dimensions of each to find the volume, then add the volumes together.
