Hi! Thank you for expressing interest in our Mustee 142 Durastall shower stall. Unlike other standard shower bases, an extended base eliminates the need to position the shower stall base directly over the floor drain, which provides greater freedom in positioning the shower. To better understand what an extended base is, please see page 1 of this specification manual. Unfortunately, this Mustee 142 shower stall has been discontinued by the manufacturer. We apologize for the inconvenience. Updating information on PlumbersStock.com is an ongoing process. However, if you want to have a shower stall with extendad bases, you may purchase the Mustee 86.500 extended base kit that can be used with the Mustee 140 standard shower stall. Uploading this Mustee 86.500's information on PlumbersStock.com is an ongoing process but you can already place the order! Just have the product number ready and contact one of our customer service representatives at 435-868-4020 between 8:00 AM and 7:00 PM MT or through e-mail at email@example.com. Happy shopping!
