No Concrete Pad
Any Level Surface
is Fine, Except Dirt,
You Don't Want Mud!



Solid Foundation

Base floorAtera® Spas, Hot Tubs and Swim Spas have a Solid Support Base Pad! A mixture of recycled resin and sawdust creates an actual foundation under the entire foot well, where combined weights often exceeds 4,000 lbs.!

This eliminates the common concrete slab requirement by all other manufacturers. Any hard level surface, that will stay level, is just fine!

No drains or jets are located in the floor! Floor fittings require a foam backing in order to gain access for repair. Over time, foam compresses from water and body weight often resulting in a sagging foot well. This condition can cause acrylic shell cracks in the foot wells and top rails! Having jets or drains in the bottom of your spa is not a good trade for a Solid Support Base Pad!

Framed Home

A Pressure treated 2"x 4" frame and corner gussets eliminate racking, providing the ultimate rigid structural support. There’s never any corrosion, rusting or twisting of galvanized tin studs! A plastic, moisture, rodent and insect barrier floor attaches to the frame. This also dramatically reduces heat and cold loss when spas are located on raised decks or freezing ground!

Atera Spa on DeckAtera Spa on Deck

Beware of non-treated lumber! It may rot and is a favorite of termites!

2" x 2" splumber should not be used for weight bearing framing studs! 2" x 2" lumber used as frame studs does not hold the heavy weight load of water, people and the vessel itself for twenty years!

Lucite XL Cast Acrylic

"Work of art" vessels are thermoformed with proven beautiful Lucite XL Cast Acrylic Microban sheet. Vinyl-ester resin and fiberglass is hand laminated to the acrylic to form a permanent bond. Polyester resin and fiberglass is then laminated to the vinyl-ester bond for additional structural support. Don't settle for acrylic or polyethylene shells without proven fiberglass reinforced plastic structural support, especially in hot climates and climates with substantial daily temperature changes.

“Old school American processes” aren't cheaper, they're far better!

There's a vast array of materials and processes used today to manufacture hot tubs and pools. Many companies are now using inferior imported components and eliminating important processes.

It's obvious to even the uneducated shopper! Kick the cabinet! Try to lift the spa, you shouldn't be able to! Find out where the components are made! It all matters!

Look carefully inside and out!

Cabinet colors

Recycled hDPE Cabinets

Atera® fabricates Eco-Smart® cabinet panels and corners entirely of recycled High Density Polyethylene for all hot tub spas. HDPE support struts are welded with HDPE rods to eliminate commonly used pressed board that delaminates during expansion and contraction as a result of changing temperatures. The result is a beautiful UV stable cabinet that does not require maintenance of any kind!

Eco-Smart® cabinets on Atera AnyTemp® Spas and Hot Tubs have a Lifetime Warranty! Inexpensive wood and PVC cabinet panels will delaminate, warp and discolor in a very short period of time if not maintained regularly. Atera Swim Spa cabinets are crafted with Inner-Seal composite panels and can be special ordered in many colors.
