The hydronic heat was already in the house when we purchased it. The baseboard heaters work quite well, but I was (am) in the process of renovating two bathrooms, one over the other. The floor of each is exposed and available for the radiant heat. I did install it myself. Most of the items are available at any big-box store. The existing system was four zones. We wanted the bathrooms to be controlled separately, so I purchased two two-way manual control valves. I went manual rather than solenoid because of ease of install and it was FAR cheaper. The two-way valves enable the system to be bypassed should the heat get too great. And unless it's REALLY cold out, that happens more often than not! The house heating now is six zones, two manual and four on thermostats.
