Why Choose an Oval or Round Tub?

Oval and round bathtubs are the ultimate choice for creating a relaxing, spa-like atmosphere. Unlike rectangular tubs that fit flush against walls, 66-inch oval tubs are often installed in custom drop-in decks or islands, allowing for creative tile work and wider surrounding ledges. Our Round Tubs take this a step further, offering massive interior width for two-person bathing that standard tubs simply can't match.

Tub Systems
The majority of our tubs come as soaking tubs, perfect for the first step in hydrotherapy, soaking in warm water. For those that want more, may have system options. Add a recirculating pump and heater to a soaking tub for a tub. Then it will not lose water temperature for as long as it is on. Choose air jets for a light skin caress or water jets that provide a deep tissue massage. Micro Bubbles give your skin a real spa treatment. Or have a combination tub that uses multiple systems. The description will list all the systems offered for each tub. Learn more about system tubs: Spa Tubs →
