In our Bridge of Don bathroom, a B-shaped bath replaces the previous shower arrangement. Its wider end serves for showering, with concealed controls away from the spray and the bath filler combined with the overflow. Those choices give the bath different ways to deliver water without treating every control as if it will be used from the same position.
On your plan, mark where you stand to start a shower, where you reach to fill the bath and where you can operate the handset when rinsing. Compare those positions with the glass, the wider end and any nearby furniture. You can ask whether each control is easy to identify and reach in its own routine, including when you are outside the bath. Grouping all the water fittings on one drawing makes it easier to catch a reach that looks fine when you consider just one of them.
