When buying a Hot Tub how does one assess the shell that is used in construction.

Quite often a cheaper acrylic may be used and one can always tell the quality producer of hot tub shells. These are usually deep tubs as some manufacturers' who use such cheap grades of material that it cannot take the manufacturing processes to get a really deep spa.

 Some times, you can see stretch marks on the bends and curves of the Hot Tub particularly so or more so with some finishes as opposed to others.

In my view, the better-built spas in the world are made with a patented four layer strengthening process, which is called Dura-Bond (tm).

This exclusive system combines the acknowledged beauty of Lucite-Xtra Acrylic with a layer of ABS for shell strength and integrity. Then the maker of the best spas in the world add a layer of double strengthening material Dura-Bond .

This high-density material is re-enforced with a fibrous chop material that adds very considerable additional strength to the Spa Shell. The process is completed with a thick layer of polyurethane foam. Lucite-Xtra  cast acrylic is a non-porous material that resists stains like the build up of lotions and body oils, which can, of course, ruin non- acrylic spas.

This tough material reains it shine and colour despite the use of sanitizing chemicals, high temperatures and exposure to sunlight. Its durable surface resists chipping, cracking and denting.

Lucite-Xtra  is easily maintained with a sponge and mild soap. No additional polishing or waxing is needed to keep its lustrous appearance. One can always check the quality of these Hot Tub Shells by applying what I call the lipstick test. Because Enderol and other similar low cost surfaces are actually porous (a great place for bacteria to manifest itself), they are of course also much less resistant to staining which is why you would see a tile line around some of their spas. If you apply lipstick, then usually it is not very easy to remove.

On high grade Acrylic, since it is non-porous, it will simply wipe right off. When you or your friends are thinking of buying a Marbella Hot Tub Spa it is always worth probing a little beneath the glitz of the packaging and presentation. Do not fall for the simle patter of a salesperson who simply repeats by rote some pre-planned presentation and very probably does not even use a Hot Tub. Make sure you buy your Marbella Hot Tub from a long established American manufacturer and not just a cheap import from the East. Our Home Page is at Best Hot Tubs Spain
