Terms for specific kind of water taps

There are two types of taps in my house, and both of them are suitable for cold, hot or mixed water.

The difference is one kind has ONE knob and the other kind has TWO.

The one-knob tap (for kitchen) controls hot and cold water together. When the knob is rotated to the left, hot water flows out, meanwhile right means cold water, and center means mixed water.

The two-knob tap (for bathroom) controls hot and cold water separately. One is for hot water and the other is for cold water.

OK, so are there two specific terms or phrases for two kinds of taps?

Thanks a lot.

Solution 1:

Single-handled and double-handled (or one- and two-handled) are the terms you'd look for while buying a faucet, and also refer to faucets with knobs. This is likely what the average customer would search for, but there are more technical terms that exist.

"Single Hole Kitchen faucet" is another term for single-handled faucets, according to here.

One specific type of two-handled faucet is the compression faucet:

Compression faucets have two separate handles. When the handle is turned, it raises or lowers a washer or seal that closes against a valve seat at the base of the stem to restrict water flow through the faucet body when you turn the handle off.
