To achieve this width, the gauge of the plastic had to be increased which results in a stiffer and more heavy duty panel than was the norm previously. Obviously this is a great benefit from a durability point of view but there are a few downsides: panels are slightly more expensive; they are a little more difficult to maneuver into place; they cannot be bent around corners as the plastic is not flexible enough. But these are only minor issues.

If the panels need to run across a wall that is wider than 1 metre there are still tongue and grooved edges so they can be slotted together without the need for a joining strip, which makes for a very neat finish.
So you are looking for inexpensive, easy to live with shower wall panels then Neptune are the obvious choice.
