You turn on the water and it's coming out of the tub spout instead of the shower. This diverter valve lets you pull to switch it over to the shower head so you can rinse off without messing with the flow.
In a tight RV bathroom, you need a faucet that fits the sink without crowding it. This black single-handle faucet keeps temperature control simple and limits flow to 1.2 GPM for water conservation.
