What is a corner tub? Corner tubs are functional, beautiful, and smart, because they are bathtubs made to fit into corners, freeing up more floor space in your bathroom. A corner tub provides you with a playful geometric twist to your bathroom floor plan. These tubs use a limited amount of space while still providing the bather with an exceptional soaking experience. Corner baths are fabricated with a flat bottom design comfortable for two occupants. These unique baths also play double for a shower. By installing glass panels or shower curtains, you can create a showering area with modern charisma. Simply put, corner baths are fashionably clever.
