What Are The Various Hot Tub Sizes?

When considering adding a hot tub to your outdoor living space, one of the most important decisions is choosing the right size. Hot tubs come in a variety of dimensions to suit different numbers of bathers and backyard footprints. Carefully measuring your available area and assessing how many people you plan to accommodate most of the time will help narrow down the ideal tub size.

Standard Hot Tub Dimensions

Hot tubs are manufactured in several common size configurations, typically ranging from small 2-person models up to larger 7-8 person tubs.

These measurements only account for the tub itself, not any external features like stairs, redwood surrounds, gazebos, etc. Be sure to factor those in when planning your space.

Typical Hot Tub Sizes By Number Of People

Let's take a closer look at common hot tub sizes based on typical seating capacity:

Small Hot Tubs (2-3 People)

The smallest hot tubs on the market can fit about 2-3 adults comfortably. A 2-person hot tub generally measures around 65 to 75 inches (5 to 6 feet) square. These compact models are best suited to small patios, balconies, or other spaces with size constraints. They make convenient soaking tubs for one or two people.

With seating for up to 3 adults, a 3-person hot tub ranges from 65 to 75 inches square as well. Some 3-person triangular hot tubs may be more space-efficient for fitting in corners.

Dimensions

Typical dimensions for small 2 to 3 person hot tubs are:

• Length - 65" to 75"
• Width - 65" to 75"
• Height - about 34" to 36"
• Weight when empty - 150 to 400 lbs

Seating Capacity

As the names imply, these petite hot tubs can comfortably accommodate:

• 2-person models seat 1 to 2 adults
• 3-person models seat 2 to 3 adults

Medium Hot Tubs (4-5 People)

For small families or groups of friends, a 4 to 5 person hot tub hits a nice sweet spot. Ranging from about 80 to 100 inches (6 to 8 feet) square, these medium hot tubs have enough room for social soaking without dominating your patio.

Dimensions

The average dimensions for a medium 4 to 5 person spa are:

• Length - 80" to 100"
• Width - 80" to 100"
• Height - about 34" to 38"
• Weight when empty - 400 to 700 lbs

Seating Capacity

In terms of number of seats, most medium hot tubs allow:

• 4-person hot tub - 3 to 4 adults
• 5-person hot tub - 4 to 5 adults

Large Hot Tubs (6+ People)

On the spacious side, hot tubs holding 6 or more people give large families, parties, and teams plenty of shoulder room. Ranging from 100 to 110 inches (about 8 to 9 feet) square, these generously sized hot tubs command attention.

Dimensions

For the biggest hot tub models, typical dimensions are:

• Length - 100" to 110"
• Width - 100" to 110"
• Height - about 36" to 40"
• Weight when empty - 700 to 900 lbs

Seating Capacity

In terms of maximum bathers, large 6+ person hot tubs allow:

• 6-person models seat 5 to 6 adults
• 7-person models seat 6 to 7 adults
• 8-person models seat 7 to 8 adults

Factors Influencing Hot Tub Size

When deciding what size hot tub is right for your backyard, there are several key factors to weigh:

Number Of Users

First, consider the number of people who will realistically use your hot tub on a regular basis. Don't size your hot tub for the rare once-a-year party. Aim for the family members or friends who will soak a few times a week.

For example, a retired couple may only need a 2 person hot tub. A family of four would likely prefer a 4 or 5 person model. Single people and couples should choose smaller hot tubs, while those with large families or who entertain bigger groups may need a 6-8 person tub.

Available Space

Carefully measure the footprint where you plan to install your hot tub. Leave ample access for entry/exit points, filter access, and service clearance. Check local codes for any setback requirements from property lines or buildings.

Make sure to accommodate stairs, surrounding decks or redwood framing, a gazebo, cover lifter, or other features that may impact placement. Having an extra 12 inches on all sides is ideal.

Features And Accessories

If certain therapeutic or entertainment features are important--like massage jets, lounge seats, or multiple control panels--make sure to choose a size hot tub that offers the options you want.

And don't forget to account for accessories like cover lifters, steps, handrails, speakers, lighting, etc. that bolster the hot tub experience but also consume precious real estate.

Measuring Existing Space For Hot Tub Installation

Once you've settled on an ideal seating capacity, it's time to quantify exactly how much area you have for your hot tub installation. Here are some best practices for measuring:

• Use a tape measure for accuracy
• Note obstructions like trees, bushes, pipes, or wires
• Map out any pathways for access or maintenance
• Double check codes for water drainage needs
• Account for ancillary features like stairs, decking, etc.

With precise measurements of your usable hot tub footprint, you can zero in on manufacturers and models guaranteed to fit the space.

Will your hot tub live outdoors or inside? Each option has unique setup requirements.

Outdoor hot tubs need firm, level grounding; sufficient wind, sun, and drainage planning--plus winterization prep for colder climates. You'll also want privacy fencing or landscaping.

Inside, moisture control, floor load ratings, and accessibility through doorways or down staircases become concerns. Proper ventilation to prevent mold is also key.

Carefully measure all entry points while moving the hot tub into position. And don't forget about future access needs for maintenance.
