Frequently Asked Questions

Q: Will this base fit my Dometic 320 toilet?

A: Yes. This base kit is designed specifically for Dometic 300, 310, and 320 series toilets. Verify your toilet model before ordering to ensure compatibility.

Q: Can I install this base myself?

A: Yes. The base bolts directly to your RV floor using the existing mounting holes. Most RV owners can complete installation in under an hour with basic tools. Ensure the floor is clean and level before mounting.

Q: What causes a toilet base to crack?

A: Excessive weight, impact during travel, freeze damage, or age-related stress can crack the plastic pedestal. A damaged base can lead to water leaks into your subfloor, making replacement important.
