I have narrowed down my search to 2 bath tubs. The Aloni Semi-Freestanding Corner Bathtub 180x80 Left Rounded Corner Acrylic White for 750€ and the BERNSTEIN Lena Corner Freestanding Bathtub with Double-Walled Construction 1050€. I like the first one best, it's slightly bigger, a nicer shape and 300 euro cheaper. I'd like an expert opinion about the value of having Double walled acrylic or single acrylic with fibreglass reinforcement which the one I like has.
