We've just renovated and have 3 bathrooms. no baths. Large walk in showers. We did, however, do the plumbing for a bath in the largest bathroom in case we ever sell it. We don't take baths, so no need to be cleaning the dust off it constantly.

If you won't use it, then I would get rid of it. Otherwise, it just becomes something else that you will have to clean and, depending upon the dimensions, cleaning around the base of a free stranding bath can be a challenge. This may also allow you to have a separate enclosed toilet, double shower and/or double vanity (if you don't already have those), which may offer more practical benefits than an infrequently used bath. If necessary, possibly consider upgrading the bath in the main bathroom to a more luxurious size so that if you do feel like soaking in the tub, that option will still be available.

Would you consider two mixers, a lower one for the bath and a higher one for the shower so there is no confusion for visitors? Safety and ease of operation should be the highest priority when looking at mixers for shower/bath combinations. If you only want to have one mixer then make the height suitable for somebody having a shower. You don't want to be bending over to adjust the temperature when showering in a shower\bath. I usually design bath mixers and spouts centered on the wall of the long side of the bath so if you need extra hot water when you are having a long soak it is easy to reach. I have never heard of the requirement for a bath mixer to be at 700mm, although this could be a good height for a bath spout depending on the depth of your bath.

Is this your only bathroom? if so consider carefully before you ditch the bath. Families with v;ery young children need a bath and personally for me having a bath is a must, especially on a cold night or after a long day at work. Baths are also still considered luxury items, top hotels always have a bath in their bathrooms. Perhaps you could combine the bath and shower, remember that bath / shower combinations are not always tacky and come in many other shapes, sizes and options now - a semi or completely sunken bath with shower can look stunning, spacious and you can still retain the bath! Houzz already has a great article on sunken baths and you can see in most images they are combined with a shower https://www.houzz.com.au/magazine/sunken-baths-for-every-bathroom-even-small-ones-stsetivw-vs~119731864
