Buyer’s Guide to 4 Person Hot Tubs

  |   Hot Tub Buying Tips   |   No comment

Are you looking for a hot tub, but due to size restrictions or space requirements need to keep it small? Maybe you need a hot tub, but only a few people intend to use it. There could be a number of reasons you might be looking for a four-person hot tub, price included. Look no further! We have the buying guide to four-person hot tub info that will get you the most bang for your buck.


Dimensions of a Four-Person Hot Tub

Depending on which brand you’re looking at, the dimensions of any hot tub are going to vary one way or another, but as a rule of thumb, these spas are generally between five and seven feet in width, length, and diameter, and can be circular, squared, or slightly rectangular in shape. If you’re looking for a spa that is small enough to fit into a specific area of your yard or home, you’ll find a variety of smaller sizes that are intended specifically for those limited spaces. Smaller hot tubs have their own list of benefits to consider, including:


  • More intimate for building relationships
  • Good for small families or couples
  • Less expensive than larger spas
  • Requires less water to fill and maintain


Layout Options

When it comes to the layout of a four-person spa, you have a few options for smaller spas are created to be cozy and space efficient. A square or rectangular model will likely be laid out with two seats each facing each other, whereas a round hot tub option usually has bench seating. You can also find 4 person hot tubs with loungers, but these are generally larger in dimensions to accommodate the size of the lounge seat.


How Many Gallons of Water Does a Four-Person Hot Tub Hold?

Speaking of filling and maintaining your spa, you may be wondering how many gallons you’ll be using each time you refresh your water. Most four-person spas hold between 300-400 gallons of water. It sounds like a lot, but when you consider the amount of time spa water lasts versus how many gallons it takes to fill a regular-sized bathtub (around 80 gallons) or to run your shower for ten minutes (25 gallons), that’s not an unreasonable amount of water.


How Much Does a Four-Person Hot Tub weigh?

If you’re considering putting your spa on a deck or other surface that is not the ground, you may be wondering if that deck is capable of handling the weight of a hot tub. This is important to consider, because most decks do have a maximum capacity weight limit.

Keep in mind that each brand and size is going to vary widely, but generally, most four-person hot tubs weigh 450-750 pounds empty, and then with water and people, can get up between 3,500-5,000 lbs.

The one exception here would be the inflatable variety of hot tubs, which start out around 75lbs, empty. And around 3,500-4,000 lbs. of water with people.


Can I Get a Four-Person Plug and Play Spa?

Although most plug-and-play (110V) model spas are made to seat two to three people, you will be able to find a couple of 110 V Spa options that fit 4 people. The Bullfrog Spas X6R model for example can be custom ordered in a plug and play configuration. Keep in mind that plug-and-play spas don’t have the same amount of power as other spas and, because of this, aren’t able to produce the same amount of massaging jet power.


Four Person Hot Tub Prices

As with all the options we’ve discussed today, the price of your spa could vary but is likely to fall between the $6,000-12,000 price range, or if you get a premium model, can go as high as $15,000, depending on your optional add-ons and luxury features. In this area, you have choices. Be sure to prioritize your most important features, and that should help keep you within your ideal budget.
