Why Choose a 66-Inch Rectangle Tub?

Rectangular bathtubs are the top choice for modern bathroom design. Their straight lines make them the easiest shape to install as an undermount beneath stone or quartz, creating a seamless, spa-like look. A 66-inch length is the ideal upgrade from a standard builder tub, providing the extra space needed for a comfortable soak without requiring the massive footprint of a 6-foot tub.

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 →
