Dometic 320 Series Wooden Toilet Seat | 385311864 | Bone | Elongated

Restore comfort and a residential look to your Dometic 320 Series RV or marine toilet with the Dometic 385311864 Wooden Toilet Seat and Lid in bone tan. This genuine Dometic OEM replacement features an extended wooden seat that delivers residential-feel comfort — and the meaningful real-world benefit of retaining heat on cold mornings at the campground or on the water. The right pick when your existing 320 Series seat is damaged, worn, or you simply want a warmer, more comfortable daily experience.

Wood Construction — Comfort AND Heat Retention

The standout feature of the 385311864 over plastic seat alternatives:

• Wooden seat construction for a residential look and feel
• Retains heat — meaningfully warmer than plastic, especially on cold mornings, late nights at the campground, or chilly mornings on the boat
• Extended seat profile for added comfort
• Sturdier feel compared to lightweight plastic alternatives

That heat-retention property is a small but genuinely meaningful comfort detail — anyone who's used a frigid plastic toilet seat in cold weather knows the difference wood makes.

For Dometic 320 Series Elongated Toilets

The 385311864 is designed for Dometic 320 Series elongated RV and marine toilets. The elongated bowl profile differentiates this from the round bowl seats used on Dometic's 310/311 Series — verify your existing toilet's bowl shape before ordering.

⚠️ Color Compatibility — Direct Match for Tan (DOM39FR), Non-Match for White (DOM59FR)

The 385311864 is a bone tan color. Color fitment guidance:

• Direct replacement for the tan color 320 Series toilet (DOM39FR) — exact color match
• Will fit the white color 320 Series toilet (DOM59FR) — same physical fitment, but NOT a color match (bone tan seat on a white toilet)

If you have the tan DOM39FR, this is the right seat for both fitment and visual match. If you have the white DOM59FR, this seat will install but the bone tan vs white color difference will be visually noticeable.

Marine and RV Heritage

The 385311864 is rated for both RV and marine applications — built to handle the moisture, vibration, and temperature swings of both environments. The wood construction holds up well across both use cases.

When to Replace Your Toilet Seat
