Dometic 310/311 RV Toilet Seat | 385311950 | Bone | Slow-Close Wood

Refresh and upgrade your Dometic ReVolution 310 or 311 RV toilet with the Dometic 385311950 Slow-Close Toilet Seat and Cover Kit in bone. This genuine Dometic OEM seat assembly transforms the daily bathroom experience — replacing the standard slamming-prone RV seat with a slow-close enameled wood design that quietly closes with a tap. The right upgrade when your existing seat is damaged, worn, or you simply want a quieter, more refined daily experience.

Slow-Close Hinge — The Real Upgrade

The standout feature of the 385311950 is the slow-close hinge system:

• Quietly closes with a tap — no more loud slamming
• Eliminates pinched fingers — meaningful for kids and inattentive moments
• Reduces wear and tear on the toilet bowl from slammed lids
• More refined daily experience — small detail that matters every time you use the bathroom

That single feature is the meaningful difference between a basic RV toilet seat and a residential-feeling one. If you've ever been woken up by an enthusiastic lid-drop, you understand the value.

For Dometic ReVolution 310 and 311 Low-Profile Toilets

The 385311950 is specifically engineered for:

• Dometic ReVolution 310 low-profile toilets
• Dometic ReVolution 311 low-profile toilets

The 385311950 fits Dometic's 310/311 series with the two-hole mounting pattern. Verify your existing toilet model and mounting hole spacing before ordering — Dometic seat assemblies are not interchangeable across all toilet model lines.

Cross-Reference: Replaces 385311940

The 385311950 is the direct replacement for the earlier Dometic 385311940 seat assembly. If your existing seat shows part number 385311940, this 385311950 is the current production successor — same fitment, same function.

⚠️ Have an Older 310/311 Toilet?

Worth knowing: the Dometic 300 Series (including the 310 and 311) is out of production and has been replaced by the Dometic 400 Series. The 385311950 seat fits your existing ReVolution 310/311 — but if you're ever ready for a full toilet replacement rather than just a seat refresh, the modern successor is the Dometic Complete 410 RV Toilet — the new-generation compact porcelain replacement for 300 Series toilets.

For now, this seat will keep your existing ReVolution 310/311 in service longer and meaningfully improve the daily experience.

Premium Enameled Wood Construction in Bone

The 385311950 is built with materials that elevate the look and feel:

• Enameled wood construction — sturdier and more residential than plastic alternatives, with a smooth easy-clean enamel surface
• Bone finish — a warm off-white that complements most RV bathroom palettes
• Residential-style design for at-home comfort
• No logo design — clean, branding-free aesthetic
• Round shape, closed front — matches the ReVolution 310/311 bowl profile

Similar But Verify Fit — Dometic 385312074

Dometic also offers the Dometic 385312074 Slow-Close Enameled Wood Toilet Seat — Bone, which is described as fitting the Dometic 310 Series model 302310083. The 385312074 and this 385311950 appear similar — both are bone enameled wood slow-close seats for the 310 Series — but they are not documented as interchangeable. Each has slightly different specifications:

• 385311950 (this seat): For Dometic ReVolution 310/311 low-profile, overall seat 14-3/8" × 15-7/16", seat hole ID 11" × 8-1/4"
• 385312074: For Dometic 310 Series model 302310083, 15-1/2" length, seat cutout 11" × 8"

Verify your existing seat's part number or your toilet's specific model designation before ordering either to ensure proper fit.

Need the White Version Instead?

This seat is the bone variant. If your existing toilet is white or you prefer a brighter aesthetic, see the Dometic 385312075 Slow-Close Wood Toilet Seat — White. Both serve the 310/311 series with slow-close wood construction — pick by your existing toilet's color.

Want a More Budget-Friendly Option?

If the premium enameled wood slow-close upgrade isn't necessary and you'd prefer a straightforward, cost-effective basic replacement for your 310 Series toilet, see the Dometic 385311647 Seat and Lid — Bone. Same bone color, polypropylene plastic construction, standard close — a no-frills replacement at a budget-friendly price point.

Marine-Grade Approved

The 385311950 is marine-grade rated — meaning it's built to withstand the constant moisture, vibration, and demanding usage conditions of marine and RV environments. That marine certification is a meaningful durability credential for a part that lives in a humid, vibration-heavy environment.

Installs in Minutes — Two-Hole Mount

The 385311950 is engineered for quick, straightforward installation:

• Two-hole mount matches the ReVolution 310/311 mounting pattern
• Bolt holes spaced 5-1/2" apart
• Mounting bolts included
• Installs in minutes — no specialty tools required

If your existing toilet has a different bolt hole spacing, this seat will not fit — verify mounting hole spacing before ordering.

Dimensions for Fitment Verification

Before ordering, verify the 385311950 will fit your toilet bowl:

• Bolt hole spacing: 5-1/2" center to center
• Seat hole inside diameter: 11" × 8-1/4"
• Overall seat outside dimensions: 14-3/8" × 15-7/16"
• Listed nominal dimensions: 14-9/16" W × 16" L
• Weight: 6 lbs

When to Replace Your Toilet Seat

Common reasons to swap in the 385311950:

• Existing seat is cracked, chipped, or damaged
• Loose, broken, or worn hinges
• Yellowed or stained surface that no longer cleans up
• Upgrade from basic plastic seat to slow-close enameled wood
• Cosmetic refresh as part of bathroom updating
• Routine wear after years of daily use

Complete Kit with Mounting Hardware

The 385311950 ships as a complete assembly:

• Seat with slow-close hinge
• Cover (lid)
• Mounting bolts

No need to source separate hardware — drop in the new assembly and you're done.
