Crosswater's Totti range looks similar and has various options which might suit you. I have a similar bath and have used a bath filler which combines with the overflow and then have hot and cold panel valves mounted on the corner near the wall on the curved end of the bath. The advantage of this is that the plumbing is accessible by taking the bath panel off, should you wish to replace the valves etc. There isn't a Totti panel valve but as these are low profile I think you could get away with using a round panel valve.

Thank you all. That’s my thinking too. We have a formal dining area in our living/dining room which is the argument my partner was making but if I had kids I think I would want to keep their food mess separate from the guest area. This is the proposed plan from a kitchen designer, but I think I would put the cooker opposite the sink (to an angle) to create our working triangle.

Will it be Ok if your future 15 year old daughter is walking downstairs in pjs to have a shower at 11am on morning because she prefers the shower downstairs? What’s the route to the shower in relation to public space where you are entertaining friends? will guests have to queue to use the loo while she is bathing? We have en-suite with stand alone bath with hand held shower and separate cave shower - luxury by previous owner. Bath rarely used but looks amazing. Our teenagers share main bathroom with shower over bath. As Johnathan says speed is the essence of the game - bath rarely used by eldest only, shower is their preference. Another question is whether you are in forever home, or may sell in the future - bath preferred by families with very small children and many families see altering bathroom to reinstall bath with power shower for adults a game changer due to expense. The answer to your issue must include how your family like to bathe, the future of your home and the position of your downstairs bathroom.
