Water will go down a drain in any direction, depending on any previous rotation the water may have had, as well as the shape of the container and any angle of the bottom of the tub or basin.
The Coriolis Effect, which determines actual and apparent spin, is a right turn (drain counter-clockwise) in the northern hemisphere and left turn (drain clockwise) in the southern hemisphere, but is a weak influence compared to the other factors that can influence the direction of spin.
Contrary to popular belief, water swirling down the drain is no related to the Earth's rotation or the Coriolis effect. The swirling vortex over the drain is likely related to angular momentum; the distance from the center of the rotation determines the speed of the rotation. o
The latitude has very little effect on the direction of sink water spinning. Please see the link below.

No. This is a matter of choice. They may spin in whichever direction they desire.
North of the equator, yes. South of the equator, they spin clockwise. Wind direction is affected by the spin of the Earth.
Does spinning water always spin in the same direction?
The Coriolis Effect only affects large bodies of water, for example, hurricanes are diverted from the equator because of the Coriolis Effect. The Coriolis effect would not affect a toilet enough to overcome the design of the fixture. The rim holes would start the swirling. Please read the Snopes page that explains this in greater detail.

Tornadoes in the northern hemisphere usually spin counterclockwise, while those south of the equator usually spin clockwise.

This is an urban myth: it does not spin in any particular way. Several studies into effects of the coriolis force have concluded that there is no evidence of a systematic direction of spin: the mass of water is too small and there are too many other, confounding factors.
North of the equator, yes. South of the equator, they spin clockwise. Wind direction is affected by the spin of the Earth.
Does spinning water always spin in the same direction?
I always thought it was from the Coriolis Effect, the Earths rotation, that the equator is moving faster than the poles that do not spin. On checking, it appears it is more a factor of how the tub or sink is made and how the water is put in it. It take time for water to come to complete rest.
South of the equator most tornadoes spin clockwise.
No, the water in a toilet does not spin one way in the northern hemisphere and spin the opposite direction in the southern hemisphere. The spin of the water in a toilet is determined by the shape of the toilet bowl and the flush system, not by the direction of the Earth's rotation. In a toilet, the water is flushed by a flushing mechanism. This flushing mechanism is usually activated by pushing a lever or pushing a button, and it causes water to be released from the tank into the bowl. The shape of the toilet bowl, as well as the type of flushing mechanism, determines how the water will move once it enters the bowl. When the toilet is flushed, the water quickly fills the bowl and then begins to swirl around. The force of the swirling water will cause it to push against the sides of the bowl and create a whirlpool effect. As the water circles around the bowl, the shape of the bowl determines the direction in which the water will spin. The water will usually spin in a clockwise direction in the northern hemisphere and in a counterclockwise direction in the southern hemisphere. The spin of the water in a toilet is determined by the shape of the toilet bowl and the type of flushing mechanism, not by the direction of the Earth's rotation. The shape of the bowl and the type of flush system will determine the direction in which the water will spin, regardless of which hemisphere the toilet is located in.
Direction of spin is dependent on the direction of the rifling on the inside bore of the barrel. A bullet will spin the same direction as the rifling.
Actually, they don't. The direction of motion is caused by the Coriolis effect. This effect is the basis of the Foucault pendulum demonstration and also causes the counterclockwise rotation of cyclones in the northern hemisphere. However, this effect in a basin or toilet is so weak that most of the time the direction of spin of draining water is the sum of other effects.

All hurricanes north of the equator spin counterclockwise.
