Description
Genuine Dometic Complete Base Kit for 111 & 511H Series Toilets
Stop chasing individual seal, valve, and spring failures — this genuine Dometic complete base kit gives you a full, brand-new base assembly for your 111 or 511H series toilet in one package. If your existing base has developed a persistent leak, a failing water valve, a weakening return spring, or other wear-related issues, replacing the entire base is often more reliable and cost-effective in the long run than repeatedly repairing individual components. This short-pedestal base kit installs in place of your old base with basic hand tools — no specialized plumbing expertise required.
Compatible With:
- Dometic 111 Series toilets
- Dometic 511H Series toilets
Key Features:
- Genuine Dometic OEM complete base assembly
- White finish to match standard 111/511H series toilets
- Includes all components needed for a full base replacement
- Eliminates the need to source and replace individual worn parts separately
- Straightforward installation: disconnect the water line, remove 4 mounting bolts, swap the base, reconnect
How to Confirm This Is the Right Base for You
This base kit is designed specifically for Dometic 111 and 511H series toilets in white — a short pedestal height base. If your toilet is bone-colored, you'll want part #385311560 instead. If you have a taller-pedestal model, a different base kit applies — check your toilet's model number and pedestal height before ordering, or contact us to confirm fitment.
Frequently Asked Questions
Why replace the whole base instead of individual parts?
If you've already replaced seals, valve components, or springs separately and are still experiencing issues, a full base replacement addresses every wear point at once — many customers find this more reliable and ultimately more cost-effective than repeated individual part replacements over time.
What's included in this kit?
This is a complete base assembly, including the internal components needed for a full base swap — you won't need to separately source seals, springs, or valve parts for this repair.
How difficult is this to install?
Most customers complete this replacement in about an hour with basic hand tools: loosen the band clamp to remove the bowl, disconnect the water line, remove the four mounting bolts holding the old base, then reverse the process to install the new base.
Will this fit my Dometic 510H or 511 series toilet?
This kit is specified for 111 and 511H series specifically. Other related models (510H, 511, 2011, etc.) may use a different base kit — check your exact model number before ordering.
What's the difference between this and part #385311560?
385311559 is the white version of this base kit; 385311560 is the identical kit in bone. Choose whichever matches your toilet's finish.
Why is this a special order item?
Complete base kits are larger, less commonly-stocked components that Dometic supplies directly upon order rather than keeping in standard retail inventory.
