Aker by Maax has been producing Top-Performance, Long-Lasting Acrylic and Gelcoat bath ware for more than 4 decades. Their bottoms are tops! By using 1/2" balsa wood in their flooring system they are able to achieve a highly durable and incredibly strong floor for their units. How strong are the floors you may ask? .... They exceed ANSI requirements and they don't require wet setting! In addition to the top of the line floor construction the rest of the unit is made with great care as well; each unit is hand rolled to help reduce air pockets and weak spots and that's not all... Aker also uses a denser resin and longer fiberglass strand than industry standard, meaning the resulting product is strong and ready to put up with years of use.
