You remove the transmission to replace the clutch. It's fairly involved on the Yaris. I think the book labour time is nearly 7hrs. You're probably looking at $700-1000 depending on where you take it and, if you need a new flywheel, it may cost another $300-400 on top. Not cheap, but rarely required and the reliability of the Yaris otherwise makes up for it.
I don't think anyone has actually touched on
why the Yaris clutch sucks so bad. The reason is because there is absolutely no feel right? When wearing workboots I literally cannot feel the engagement point of the clutch because the pedal is so light. The main reason for this is the diaphragm spring on the pressure plate are very light. This is the essentially the part that your foot is pushing against (after a bit of hydraulics and leverage). So get a clutch with heavier diaphragm springs would make a big difference. As mentioned before, performance clutches feel better because they have heavy diaphragm springs to give better clamping force on the clutch disc. I have not tried one in a Yaris yet, but it should make a world of difference in pedal feel. A performance clutch is probably a very good idea for people who just want better clutch feel than OE.
That being said, I don't know that I want one in my car
I've learned from past experiences that clutches are cheap compared to transmissions. From
much higher horsepower cars than the Yaris, but I typically run weak clutches in my cars so that the clutch breaks before the transmission etc. Clutches are cheap compared to hard parts.
Cheers.
Also, this is an excellent video on how clutches work:
