A spa fixture assembly includes a resilient grommet, a fixture body (e.g., a jet valve body), and a fixture cartridge (e.g., a combined jet valve and cover). The grommet has a body having an inner surface and an outer surface and a lip, with the inner surface preferably tapering away from the lip. The fixture body has a water entry port, an air conduit, a lip, and a threaded insert holder. The fixture cartridge includes a body having external threads, a front peripheral cover, and an insert (e.g., a jet valve). The grommet is inserted from either the front or back of a tub through a hole drilled in a tub wall until the lip of the grommet seats flush with the tub wall. The fixture body is inserted through the grommet (towards the tapered end of the grommet) from the back of tub until the lip of the fixture body seats against the lip of the grommet and is thereby interference fit within the grommet. The fixture cartridge is thread into the fixture body from the front of tub (i.e., from inside the tub), and the peripheral cover portion cosmetically covers the portions of the grommet and fixture body which extend through the tub wall, and further locks the fixture body in place.
