Frequently Asked Questions
Will this base kit fit my Dometic toilet?
Yes, this kit is designed for Dometic 300, 310, and 320 series toilets. Check your toilet model number on the tank or lid to confirm compatibility before ordering.
What's included in the kit?
The base kit includes the plastic base assembly, mounting bolts, and sealing gaskets. Everything you need for a complete installation is included—no additional hardware required.
How do I know if I need a new base kit?
Replace your base kit if you notice water leaking around the toilet base, the toilet rocks or moves when you sit on it, or you see cracks in the plastic base. A worn base compromises the seal to your waste tank.
