Door for Suburban Nautilus Series On Demand Water Heater

Which Suburban Nautilus on-demand water heater models do these doors fit?

These replacement doors are designed for the Suburban Nautilus series tankless on-demand water heater. Confirm your model number on the unit's data plate before ordering, as Suburban's standard tank-style water heaters use a different door footprint. If you have a standard SW-series tank heater instead of a Nautilus tankless unit, see our Suburban on-demand water heater tankless doors collection for the correct fit.

What color and finish options are available for the Nautilus door?

Available finishes typically include polar white and colonial white to match common RV sidewall colors. Check the product variant selector on each listing for current color availability. If you are replacing other exterior service doors at the same time, our GE Appliances RV water heater doors collection covers comparable finish options for other water heater brands.

Can I install the replacement door myself?

Yes. The Nautilus door installs with standard hand tools and uses the existing mounting holes on the heater's flange. Most owners complete the swap in 15 to 30 minutes. Inspect the door seal and hinges before reinstalling, and replace any cracked or deformed components to maintain a weathertight seal.

Does the door include the lock, hinges, and gasket?

Contents vary by part number. Some listings include the complete door assembly with hinges, latch, and gasket, while others ship the door panel only. Review the product description and included parts list on each listing before ordering. Need help confirming the right part for your Nautilus unit? Text or call our team at 817-984-1852.
