The first thing you need to figure out is what the water pressure is in the bathroom. Then you'll know if you need a booster pump or not. Your looking for at least 50psi, more is better. Most houses have a pressure regulator that caps the pressure at 50 to 60psi. But it drops the further you get from the regulator and also when the pipe drops in diameter. where the regulator is it's probably 3/4" pipe and in the bathroom it's dropped down to 1/2"

A 75 or 100gpd system should work fine for you. The only difference between the two is the actual RO membrane and the flow restrictor.

In a bathroom an RO/DI system can take up quite a bit of space under a vanity. You might want to put in some quick connects for it too. Then you can store it somewhere else when not in use.

any RO unit will have 3 small 1/4" pipes. One is the water in, one is the RO water out and one is the waste water out.

You can put the unit itself anywhere. Under a bathroom sink is a great spot. You can tap your supply line off your sink water, and put the waste water to the drain. If you go to home depot and ask them for adapters to connect 1/4" tubing to the cold water and P-trap of a sink they can help you out there.

For the RO water, well run it where ever you put your bucket/tank/trash can that you want to use to store the water. If you plan to use it a lot, I would get a REALLY long line and run it in the walls or ceilings. If you only use it once a month, then just coil it up and store it under the sink until you need it.

If thats to complex for you, just get a trash can, mount the RO to it and get a garden hose adapter for the RO. I had mine like that for years before I got a house with a basement.

RO/DI works BEST at 65 PSI across the membrane (after going through prefilters) and ambient water temperature of 77F (which you can't control. Do NOT run hot/warm water through a membrane).

A booster pump makes a world of difference.
