Tiling infront or behind a back to wall bath with lip

[AverageAndy]

Hi, I have brought the following bath from B&Q.

GoodHome Nakina Gloss White Acrylic Back to wall D-shaped Double ended Bath

GoodHome Gloss White Back to wall Acrylic D-shaped Double ended Bath (L)1600mm (W)750mm | DIY at B&Q

The Nakina white freestanding bath has an indulgent design which can create a stunning focal point in your bathroom. With greater flexibility with where you place the bath, it is ideal for larger bathrooms. It’s designed so you can choose where to place your bath taps and holds 205L of water.

For any previous back to wall baths I have always tiled infront of the bath and on top of the side of the bath. However, this bath has confused me as it's a back to wall bath but with a lip on the side which I feel should go against the tile and therefore I should tile behind the bath and the lip will protect water leaking in behind (with a seal obviously).

Has anyone fitted a similar bath or this one and got any advice. Thanks

Seems like it would work with tiling completed first then this pushed up to meet and sealed.

Thanks. Going to take a closer look when it arrives.
