Hot Tub Installation Cost

An outdoor hot tub can instantly transform your patio or deck into a spa-like retreat, a romantic destination or a therapeutic tool to help you unwind at the end of the day. High-quality hot tubs can even increase the overall value of your home, which might be an advantage if you are planning to sell the property in the future. With so many different types of hot tubs on the market, and an average cost of installation that ranges from $277 to $395, it can be tough to know which type is best. Use this guide to better understand the costs of various hot tubs.

Wood Fired Hot Tubs

If you want a permanent hot tub that looks rustic and requires very little maintenance over time, one great option is the wood fired hot tubs. Rather than using electricity or gas, these tubs operate by burning traditional logs of wood to heat the water. These tubs may be heavy, but they don't require any electric wiring or plumbing since they are standalone items that can be placed anywhere. Plus, wood fired hot tubs typically cost far less than traditional versions, and average prices may be well under $2,000 depending on size.

Portable & Inflatable Hot Tubs

If you want to set up a hot tub and then remove it in the winter, or if you like to travel with a hot tub, a small inflatable version might be best. As long as you have a flat surface, you can install it on your own within an hour. These hot tubs are also the cheapest, and they can cost upwards of $400 for the basic models.

Traditional Hot Tub Materials

Wood-burning and portable hot tubs are definitely viable options, but the more traditional version is one made from vinyl, fiberglass or acrylic. Seating in these varieties is comfortable, and cleaning is very easy thanks to the flat, smooth surface of these options.

Installation Location

If you have a compacted space ready for a hot tub, your installation costs will remain low. If you need to build a deck or pour concrete for the tub, however, expect your price to go well beyond the $395 limit mentioned above.

Hot Tub & Spa Benefits

There are so many benefits to hot tub ownership! Some of the most obvious benefits include relaxation, therapeutic exercise and, of course, just plain fun! 

Here's to Your Relaxation

  • A past study shows that 70% of employed Americans suffer stress-related conditions, such as depression, ulcers, high blood pressure, anxiety and insomnia.
  • A National Sleep Foundation study found that a 15-minute soak in hot water can actually help you fall asleep faster.
  • Studies show that warm water allows your blood vessels to dilate, allowing more blood and oxygen to flow to your muscles – and you relax!
  • More than 50% of hot tub/spa owners cite relaxation as the primary reason for purchasing a hot tub or spa.

Spas and hot tubs are a great getaway from your daily routine. Warm, smooth bubbling water can turn even the most stressful day into pure pleasure – just for fun, just for romance or just because!

Here's to Your Health

Water exercise is proven to be a safe and effective way to stay in shape. In fact, water exercise can be safe for many people that can't participate in other forms of activity. The soothing heat and buoyancy of water creates an ideal environment for relieving the pain of many chronic health conditions such as arthritis, fibromyalgia and orthopedic injuries. Water supports sore joints to encourage ease of movement while at the same time providing gentle resistance to build strength and muscle. As with any health regimen, consult a physician prior to beginning a new exercise program.

Here's to Your Entertainment

For a party of many or a party of one, hot tubs and spas are THE source for enjoyment, amusement and pleasure. It's a perfect environment for the whole family to come together, relax and spend time together. You could also grill out with family and friends, or just enjoy a romantic evening with your spouse. The entertainment possibilities are endless, and the best part is that you never have to leave home – your escape is only steps away!

Here's to Your Home Improvement

Your home will look better and you'll feel better with the addition of a new spa or hot tub. You can say goodbye to membership dues, travel reservations and extra recreational fees … your dollars are invested in you, your home, your family – now and for the future – there's no better investment!

Did You Know?

  • A typical hot tub costs about $10 - $30 per month in electricity to operate (based on a range of $.07/kWh - $.10/kWh. The 2003 US national average is $.0871/kWh.)
  • A hot tub that is installed in a sunny location can use up to 5% LESS electricity than one installed in the shade.
  • Hot tub owners can save about 5% by minimizing heat loss due to wind. Shelter your hot tub by planting shrubs and/or installing a fence.

Hot Tub & Spa Accessories

There are so many options available to make your hot tub or spa as simple or sophisticated as you want. Jet types and seating configurations can be customized to fit specific preferences, rather than just using the pre-installed ones in the tub already. You can also add drink trays or high tables outside of the hot tub if you want to eat or drink while in the tub. There’s also the option of fiber optic mood lighting at night to make it seem like the right kind of atmosphere, especially if you’re having a party with friends. Built-in stereos and TVs are another good idea if you’re having a party with friends. There are even spa-friendly game boards that you can have floating in the hot tub to play.

Then there are other kinds of accessories to consider, like the cover. Sometimes these don’t come automatically with the hot tub, which means you’ll need to find one that fits the confines of the hot tub and can withstand the weather conditions. You want to avoid children or pets falling in, along with having to clean because of trees, shrubs and bugs. You also to have think about the filter, which will need to be changed at times, as well as the water chemicals needed to keep it at a certain pH level. You should also have a thermometer to monitor the temperature of the hot tub so it stays just the way you like it rather than too hot or cold. Also, you’ll need to consider cleaning accessories for when you do need to maintain it. Whether it’s netting, a scrubber, vacuum, skimmer or any other kind of supply you might need, you'll most likely have to purchase these accessories if you buy a hot tub.
