Hi Steve and thanks for getting in touch. The units as you describe have not been part of the Portsman Range but there are so many similar styles of bathroom furniture available these days that it is understandable you may have thought otherwise.
Next, for example, have a range by the name of Malvern which is the same style and does have some options with baskets. There will be other better examples, of course, but this is the one that first sprang to mind.
Sorry I couldn't have been more help and best wishes.
