Will the 32W bulb fit where the 22W bulb was?

No. The 22W is an 8-inch ring and the 32W is a 12-inch ring, so they fit different fixtures. Check your fixture's ring size before ordering.

The 32W bulb, at 1950 lumens versus 1400 for the 22W. That is about 40% more light.

They are close. The 22W is rated 12,000 hours; the 32W is rated about 5.5 years, roughly 12,000 hours at 6 hours a day.

Which is better for a bathroom?

The 22W, because its 3000K warm white light is easier on the eye in a small room. The 32W cool white suits utility areas and larger rooms.

Is the 22W worth $159 at Distritech?

That is high for a fluorescent circline. Compare against other stores before buying, and weigh an LED circline retrofit, which uses less power and lasts longer.

Do both use the same base?

Yes, both use a G10q 4-pin base. The ring diameter, not the base, is what usually rules one out.

GE Lighting 22W Circline Fluorescent Bulb, 7-Inch, T9, Cool White, G10q Base vs General Electric Fluorescent 32 W Cool White Circline Tube Light Bulb

Buy the 22W 7-inch bulb if your fixture is a smaller circline ring and you want warm white light; buy the 32W 12-inch bulb if your fixture takes the larger ring and you need more light. The 22W is listed at $159 at Distritech as of November 3; no price was given for the 32W. Match the ring diameter and the G10q 4-pin base to your fixture first, because these two bulbs do not fit the same socket plate.
