TUFF SPAS are Eco Spas

Hard Top Hot Tubs by Colorado Custom Spas

Tuff Spas are environmentally friendly hot tubs.  They are made from recyclable materials and are extremely energy efficient.  No VOC’s are emitted during the manufacturing process.  Tuff Spas are solar friendly.  If you are looking for an Eco Spa, there is no better option.

Withstanding the test of time

The Tuff Spa design offers many advantages over conventional acrylic hot tubs:


Energy Efficiency

Tuff Spas are amongst the most energy efficient hot tubs available. The exclusive Tuff Top hard top cover is filled with high quality insulation and incorporates a rubber gasket around the perimeter, just like your refrigerator door or a Yeti cooler. Heat rises, making the cover an integral component in building an energy efficient hot tub. Traditional vinyl covers just can’t compete.


Ease of Operation

Spend time enjoying your hot tub, not maintaining it. There is no complicated programming, just set it and forget it. No need to add harsh chemicals every day with our all natural water treatment and conditioner system. The exclusive Tuff Top hard cover makes it easy for one person to open and close the lid. Tuff Spas’ shell, cover, and siding require no special maintenance.


Plug N Play

Tuff Spas require only a 120V, 20 amp electrical outlet, saving you time and money. (All models are easily convertible to 220V at any time. Platinum models are 220v only)



You’ll enjoy peace of mind knowing that your spa shell, structure and cover are backed by the industry's best warranties.



Tuff Spas’ solid one piece bottom allows you to place your hot tub on any flat, level surface. There is no need for an expensive concrete pad. Tuff Spas are extremely light weight making them very easy to relocate. With no special wiring required, Tuff Spas truly are a portable hot tub.


Eco Spas

Tuff Spas are manufactured using eco friendly materials such as Blue Stuff insulation, which is made from recycled blue jean material. Traditional hot tub insulation methods release toxic VOCs (Volatile Organic Compounds) into the atmosphere.


Plumbing And Equipment

There are easy access panels on each side of a Tuff Spa. These are removable, allowing easy access to the plumbing and equipment should the need for repair arise.
