This is an optional upgrade for the Dometic 310 or 311 toilet. The toilet comes standard with a plastic seat. If you would like an enameled wood seat, you can order it and install it yourself in just minutes. Just remove old seat, align vacuum breaker cover, fasten new seat assembly and cover the two bolts. This seat is different from a standard toilet seat because it has an integrated vacuum breaker cover.
Bolts are spaced 5-5/8" apart. Available in white or bone.
Remember that the 320/311 model comes standard with a wood seat.
