Master bath remodel just started in earnest. We have a plan: walk in shower, Toto Dartmouth toilet, clawfoot tub, and double vanity. No major plumbing relocation although drains and supplies will be moved within a few feet of existing (but in the same joist bays, same vents, main drains, etc).

The most complicated part is going to be the shower. We aren't looking for anything too fancy:
Rainhead shower
Separate Handspray

I just started searching for products to do this and it's making my head spin. Separate thermostat and diverter valves, Bars that have both the shower and handspray in one, single valves that also do the diverting, etc.

Do you all have a go-to valve for installations like this? It seems like Kohler, Moen, Delta, and others all have plenty of choices.
Any products or installation types that are not worth the hassle?
