Frequently Asked Questions

Will this seat fit my Dometic RV toilet?

This seat is designed for Dometic 310, 510, and 710 series toilets. To verify compatibility, check the model number on your toilet base or measure your existing seat. The mounting holes should match the standard Dometic configuration. If you have a different Dometic series (like 300 or 320), you may need a different seat assembly.

Does this include the mounting hardware?

Yes, the Dometic 33219 includes integrated hinge hardware as part of the seat and cover assembly. However, you may need to reuse your existing mounting bolts that attach the seat to the toilet base, or purchase them separately if yours are damaged or missing.

How do I remove my old toilet seat?

Most Dometic RV toilet seats are secured with two bolts accessible from underneath the toilet bowl rim. You'll typically need a wrench or socket to remove the nuts from below while holding the bolt heads from above. Once removed, the old seat lifts off and the new one installs in reverse order.

Is this seat the same quality as the original?

Yes, this is a genuine Dometic OEM replacement part manufactured to the same specifications as the seat that came with your toilet. It's not an aftermarket substitute—it's the exact same part Dometic uses in new toilet production, ensuring proper fit, durability, and performance.
