They`re pretty readily available through (for instance) Amazon:

Make sure you get one that uses DC input to switch an AC output.  I have one
switching the 600W bed heater in a 3D printer.  It`s controlled by the 12V
bed-heater output on the printer motherboard, but this one should be
directly controllable by a Raspberry Pi GPIO pin.  If that proves to not
quite be the case, a transistor and resistor would let you switch the SSR
with 5V instead of 3.3V.
