Hot Tubs

A Guide to Understanding Hot Tubs

Cheesy movie references aside, hot tubs are a hot item. Whether manufactured or home-made, hot tubs act as a small pool full of heated water, many with massaging jets to further help with relaxation. While most are located outdoors, other variants -- called spas -- can be placed indoors for style or convenience purposes.

Types of Hot Tubs

• Above-ground acrylic hot tubs are usually the most popular models. Standing above ground, they have electrical jet systems and occasionally require a special electrical outlet. While they are technically "portable," they are very difficult to move, and they require a flat surface for proper installation.
• Inflatable and portable hot tubs are the cheapest hot tub models, and considerably less durable than a standard above-ground unit. Made of vinyl, nylon and plastic, they can be set up anywhere. Few use traditional jets, so many have blower systems to circulate air in the water, but this is known to cool the water down faster.
• Wooden hot tubs can run on electrical, gas or wood heat sources. Though they lack seating and heavy duty jets like other spas, their wood boasts natural aromatherapy. Like other above-ground models, wooden hot tubs require a hard surface for installation.
• In-ground spas are the priciest hot tubs, but they also are the highest quality. The cost is a result of the required excavation, plumbing and electrical work involved before the application of concrete. While more expensive to maintain, they heat faster, hold heat better and are likely to raise the value of your home.
• Home-made hot tubs are common in the Midwest. All above-ground, they lack major jet systems, but they appeal to people looking purely for hot soakers. You can find supplies and instructions at your local home improvement store, and the overall cost can range anywhere from $200 to $1,000 plus labor time.

Important Hot Tub Features

• Heaters in hot tubs are double-edged swords. Power ranges from 1.5 to 11.5 KW, and the more powerful the heater, the faster the spa will heat up. However, more powerful heaters also cost more in energy use. Ultimately it comes down to an age-old question of what's more important to you: time or money.
• Pumps are necessary for all hot tubs, but their location and noise level are determining factors for convenience. Test out the noise level of your pump before purchasing it to make sure it's at least tolerable -- nothing throws off your relaxation like loud noises.
• Good seating is subjective. While some hot tubs have no seating -- like wooden hot tubs -- those that do offer a wide range of options, from number, configuration, depth and type. Before purchasing your hot tub, actually sit in it (with others, if applicable) to ensure you have enough space to be comfortable and to move around. Also, if you know your hot tub will be used for large social events, ensure there is enough internal space and seating for the number of parties you expect to include.
• Jets in hot tubs today range from one to 160 per tub and come in dozens of different types. Important notes to consider: the location of the jets in comparison to your back. If you sit in the tub, see how high/low the jets are set for you, and consider if you like that location. If not, look for a different tub. Also, be aware of what type of jets the tub has, what they do and how they are controlled. It's all about comfort and convenience for you, so shop around.
• Covers should come with any tub you purchase. They are absolutely necessary to protect your tub from nature and to protect children and pets from the tub. Also consider investing in a cover lifter, as covers can weigh anywhere from 150 to 200 pounds.

Hot Tub Installation & Sanitation

While some hot tubs can be installed from home, consider investing the extra money for a professional. That way, any damage to the tub or property will be covered by either the manufacturer or the installer. Also, professional installers can ensure the tub has proper insulation, which consists of completely filling the base around the understructure, reducing noise. If you are concerned about servicing -- which can be hindered with a solid layer -- then layered insulation can be arranged.

Sanitation with hot tubs is extremely important for preventing disease and damage. This, like with pool water, can be maintained with an effective filter system in addition to chemical treatments. Hot, moist areas are ideal for the growth of bacteria and mold, so occasional "shocking" may be necessary as well. The "shocking" process involves large doses of potassium peroxymonosulfate (non-chlorine) or granulated chlorine, and requires non-use of the tub following treatment: 15 minutes for non-chlorine shock and 8 hours for chlorine.

Hot Tubs Cost

Hot tub costs vary by design and manufacturer. Above-ground acrylic hot tubs, for example, cost anywhere from $3,000 to $10,000, while inflatable hot tubs only estimate in value from $800 to $2,000. Wooden hot tubs retail similarly to acrylic above-ground models, from $1,500 to $5,000. In-ground spas cost $5,000 and up, and though they are most expensive, they can significantly improve property value. Unlike many home fixtures, hot tubs are generally priced according to value and reliability, making shopping for them easier.
