The CHI acrylic Undermount tub from Valley Acrylic is attractive, durable, functional, and easy to install. Valley Acrylic tubs are built using a proprietary layering technology to reinforce and insulate the tubs far better than other tubs available today. The process starts with a heavy acrylic sheet with a resin and fiberglass mixture backing then a thick layer of real Canadian wood is applied to the tub which is then coated with another layer of the proprietary resin. This gives the tub better heat retention and insulation than another acrylic, gel coat, or steel tub products on the market while giving unparalleled strength and rigidity. The proprietary layered technology insulates the tub rather than absorbing heat from the water like cast iron which saves energy and water by retaining more heat and making the addition of hot water less frequently to maintain a warm bath. The 57.5" size is a convenient under-mount size allowing for ample space in the bath and is frequently used for new construction or remodeling under-mount applications. The under-mount style mounts under the tub deck to provide a clean and efficient appearance and removes any barrier from stepping down into the tub. The heavy 3mm thick acrylic layer provides a high gloss surface that is scratch, fade, and crack resistant providing a clean and attractive appearance through the entire long life of the tub. The vibrant surface of the Acrylic tubs cleans up easily with mild soap and water, no scrubbing or harsh chemical cleaners are required. This easy-to-clean nonporous acrylic surface resists the growth of mold, mildew, and mineral deposits providing a safe and hygienic bathing fixture for your family. The CHI tub has a convenient end drain configuration and a luxurious 17.75" water depth in the large rectangular interior. Valley Acrylic, a woman-owned business, creates handmade products that are eco-friendly and manufactured in a Certified Zero Waste factory in Mission, BC, Canada.

The sleek and crisp design of this contemporary drop-in tub will fit smoothly into your personal haven or multi-use bathroom. This bath can be easily dropped-in or under-mounted with the flexibility of a left or right-hand installation. Our soaking bathtubs are intended to enhance the natural healing properties of a warm water soak, while gently supporting your body through ergonomic design. We want to help create a serene bathing experience allowing for mind and body serenity.
