Portable Hot Tub Spa

The above ground portable hot tub spa with a fiberglass or foam under-structure and a wood or synthetic cabinet is the most popular type sold in the U.S. Although these hot tubs are considered portable, they are fairly difficult to move and require a firm surface, such as a concrete pad, for proper installation; some models also need a special electrical outlet. The main drawbacks of acrylic hot tubs are a tendency for their surfaces to bubble or crack over time after prolonged exposure to sunlight, their high electricity costs (up to $50 per month) and their high price overall. Still, with over 100 manufacturers and countless options and add-ons, acrylic portable hot tub spa remain the best all-around choice for most families. Much of the information on this page comes from The Spa Depot, the largest Internet retailer of hot tubs, spa supplies, and parts in the world.

Setting up a Spa

Setup is really no big deal, if you do a little advance planning and preparation.  We'll show you what you need to do to make your installation as smooth as possible. Also, be sure to read your entire owner's manual, prior to installation.

Site Selection

You may already have a special indoor or outdoor spot picked out for your new portable hot tub spa, whether it be a lightweight soft spa such as SuperTub, or a larger model such as DreamMaker or full-sized Belize Spas.  Regardless, it is your responsibility to make sure the site is properly prepared, whether on the ground, on a floor, deck, patio or slab.

All of the portable spas we sell are designed for either outdoor or indoor installation, although most people prefer outdoors. Make sure that you observe the following:

• Since a filled spa will have considerable weight, make sure it is placed on a structurally-sound surface which will support the weight of the portable spa, water, and occupants.  Uneven and unsound surfaces can damage the spa and void your warranty.
• If outdoors, make sure that the site has adequate drainage so that rainwater will not be able to pool around the spa.
• Level the surface before filling spa with water.
• Plan in advance for proper access to power source and circuit panels.
• Leave access to the hot tub's removable equipment compartment panel for future service needs.

Preparing an Outdoor Site

Most spa owners will put their new portable hot tub spa outdoors.  Here we describe various options to provide a firm level surface, unless you already have a suitable existing patio.  Keep in mind that installing your spa on the ground without a perimeter boardwalk, paver stone, concrete sidewalk or other suitable walkway will result in an increase in the amount of debris that is inadvertently brought into the hot tub on user's feet.  A perimeter walkway can of course be added later.

Gravel Base

Gravel or crushed rock is one of the least expensive materials for a spa base.  Be sure that the ground underneath is properly compacted to prevent future settling, level, and that rainwater drainage is considered.  An access walkway of stepping stones is a nice finishing touch.

Poured Concrete Slab

Concrete is a good, long-term foundation base.  Although not inexpensive, it's low maintenance and adds value to your home. Reinforced concrete at least four inches thick, that can support a weight of at least 115 lbs. per square foot is recommended, especially for larger spas.  Make sure concrete is fully cured before placing spa, and code conforming.   Consider the many textures, patterns and colors of decorative stamped concrete.

Paver Stone

		Concrete pavers are a beautiful base material, available in a wide array of choices.  Whether you do-it-yourself, or hire a landscaping contractor, make certain that the base is prepared according to the stone manufacturer's specifications and leveled to ensure a stable foundation.

Deck Installations

If you plan a deck site, you must first determine the deck's maximum load capacity.  Consult with a qualified building contractor or structural engineer before placing your portable hot tub spa on an elevated deck.  The manufacturer of your spa can give you its filled weight.  Remember to also add the weight of the occupants.  The spa's weight per square foot must not exceed the rated capacity of the structure to avoid damage and possible injury.

Deck designs and configurations are limited only by one's imagination.  Set-top deck installations are best because they allow easy access to the spa cabinet for cleaning and maintenance.  If you decide to build a deck around your hot tub, be sure to allow for access to the equipment compartment panel so that future service is not hindered.
