The Dometic 302320081 will replace your 310 toilet, but it is not an exact same-size replacement. The 302320081 has a deeper, elongated bowl, so we recommend measuring from the wall behind your current toilet to the center of the floor flange/drain opening. The 302320081 typically needs about 11 inches of space there, while the 310 is typically closer to 10 inches. We also recommend checking the available space in front of the toilet to make sure the deeper bowl will fit properly.
