Frequently Asked Questions

Will this bowl fit my Dometic 320 or 330 toilet?
No. This bowl assembly is engineered specifically for 300 and 310 series toilets. The 320 and 330 series use different mounting patterns and bowl dimensions. Verify your toilet model before ordering.

Do I need to replace the entire toilet, or just the bowl?
Just the bowl. This assembly replaces only the basin component. Your existing base, flush mechanism, and mounting hardware remain in place. This makes it a cost-effective repair.

What tools do I need to install this bowl?
You'll need a wrench or socket set to remove the bolts holding the old bowl to the base, and a caulking gun for the waterproof sealant. The installation typically takes 15–20 minutes.
