The sizes provided in the titles of our shower doors correspond to the size of the shower tray they'll fit against. It's important to note that the shower door itself won't be, for example, 1500mm if it is to be used with a 1500mm x 1500mm shower tray. This is to make room for a side panel (if one is to be used) or tiling if the shower door is to be fitted in a fixed recess.
We include accurate measurements of shower doors within the ‘Dimensions’ tab on each product.
