Separate temp/flow bathtub controls
My current bathtub/shower has one control for turning on the water, and it starts with cold water, then a mixture of hot/cold, and lastly just hot, but I cannot get a small trickle of hot water - only a gushing stream. I want to be able to control both the temperature and the flow and be able to turn on the hot water separately from the cold water. My current controls are broken (I've tried to fix them with no luck), and now the controls go from gushing cold to gushing scalding hot with nothing between and no option of a slow stream of hot water.
What kind of fixture do I need to get in order to have this kind of control? In 1988 I redid my mother's bathroom and used a Delta faucet that was one handle that you lift up to turn on the water and move to the left or right for hot and cold. This way she could have a slow stream of hot or warm water. I have not seen this type of fixture recently, and mainly I have seen the type that I already have and hate.
I am not far from faucetdepot.com, which is located in Commerce, CA, about a 40 minute drive from my house, but they are closed today. Home Depot has a horrible selection, and Lowes' appears to be similar.
