I love these Roman/Asian style baths, My favourite but I would make the front side high and wide enough to sit on and use this to get in and out of the bath, the wall side make flush to save space. Mosaic tiles for the tub and perhaps back wall. Not necessary for sloping ends. Great safe baths for showers as well, love it Use a shower curtain

Aluminium does under go oxidation, although it is white. Unlike iron oxidation which is orange. If the tile is designed for use in a wet area it is probably coated or anodised to prevent white oxidation. Check if cleaning will be a hassle (risk stripping the coating).

How long until you renovate your bathroom again? Something that is "quite trendy at the moment" works fine if you are a real estate flipper, but can start to look very dated after 10 years. If you are planning to use your bathroom for more than 10 years before the next renovation go classic, rather than trendy. Of course Beaumonts tiles want you go with something on-trend as that is how the suppliers market their products, so it will date, and somebody will want to replace it with something else that is on-trend in ten years time!

You will need a bath with three or four tile flanges to match the one in the first photo. It has to do with complying with the building regulations for waterproofing and protecting the timber framing that is under the tiles. If the edge of the bath where it meets the tiles is not properly protected from water seeping through then concealed wet rot could start, and eventually everything will need to be ripped out, and built again. Sometimes even the timber floor joists under the bath rot out and need to be replaced. So I would do your research and co-ordinate carefully with your builder to ensure that the details are correctly built. Some builders will not go to the trouble of getting it right as they don't care if your bath falls through a rotten floor in ten years time. Quite often your choices in the bathroom should also take into account the long term functionality of the bathroom, rather than just the aesthetics.
