Frequently Asked Questions
What exactly is included in this kit?
This kit includes the complete toilet lower assembly: the base bowl, seat, and metal flush lever. It replaces the entire bottom portion of your 510PS toilet, making it ideal when the base is cracked, permanently stained, or the mounting points are damaged.
Will this Bone color match my existing RV toilet?
Bone is a classic off-white/beige color that was standard in many RVs from the 1990s and early 2000s. If your current toilet has a cream or beige tone rather than bright white, this Bone finish should coordinate well. Dometic also offers this same kit in white if you need an exact match to newer white fixtures.
Can I replace just the base without replacing the entire toilet?
Yes, that's exactly what this kit is designed for. If your 510PS toilet's upper tank and water valve assembly are still functioning properly, you can replace just the lower base assembly rather than buying a complete new toilet—saving both money and installation time.
Is this compatible with the Dometic 300 Series toilet?
Yes, the 510PS is part of Dometic's 300 Series residential-style toilet line. The 510PS, 10PS, and 300 Series designations are often used interchangeably for this toilet model, and this base kit fits all variations.
