Valley Acrylic multi-layered shower bases are made with a proprietary process that ensures the product is stronger and more durable than other products on the market. Each Shower Base has a thick layer of hi-gloss acrylic that is non-porous, attractive, and resists mold and mildew growth making the Valley product hygienic and perfect for your home. The acrylic surface sheet is reinforced with a proprietary resin material which is covered by a layer of Canadian wood and another layer of proprietary resin material to reinforce the base and eliminate the flexing experienced in other products. There are many inexpensive upgrades you can change in your bathroom later, but you want to put the very best shower base or Tub in your bath to ensure no leaks and save the expense of having to replace the unit later. Valley Acrylic provides the very best tubs and shower bases in the market. The double threshold shower base is used with two walls with an open front and side for a shower door or curtain. The threshold is 3" wide and 4" tall to allow for a standard shower door installation and tall enough to work well with a shower curtain. The Valley Acrylic shower bases have a tall and strong tile flange around each wall side to allow for the extra overhang of the wallboard to ensure a leak-free installation. This fantastic Eco-Friendly shower base includes a slip-resistant floor for added safety and a Right offset Linear drain that accepts a standard 3.25" shower drain. The matching linear shower drain and cover provide a simple and clean appearance while covering the drain assembly. The offset drain makes replacing a tub with the shower easier because you don't have to move the drain to the center. Valley Acrylic produces this line of shower bases in an eco-friendly zero-waste factory in B.C. Canada and is a certified Woman-Owned Business.
