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.

it's time for this bath to be retired back to the paddock...post a plan of the bathroom including measurements, size and location of doors and windows to invite suggestions for an upgrade

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
