Our Isata 3 has a 2 handle shower fixture. Has anyone seen a single handle unit for rvs? The shower is tight and it's easy to bump the handles. The hose grabs them as well. A single round knob makes a lot more sense in my opinion.
The only one I've seen with a knob, comes with dual knobs. The singles all appear to be handles. On RV Upgrades, you can do a search for shower faucet. I hope this helps.
