Napoli's sculptural shape and artful aesthetic wraps bathers in soothing luxury. As with all Victoria & Albert tubs, the Napoli is manufactured using “Englishcast,” a trademarked blend of volcanic limestone and high-performance resins. The company claims the material is stronger and better for the planet than acrylic; a 25-year warranty underlines the assertion. Victoria & Albert Bath, 800.421.7189; www.englishtubs.com.
