Choose the lower edge for the installation
The guide retains the bottom trim for an elevated firebox. It describes removing that section for a firebox installed at floor level; another bottom-trim purchase is not a missing standard part.

FinishBlack metal
A considered finish around the hearth.
The 38-inch RBF30TRIM38 frames the 30-inch RBF30 Revillusion firebox with a black metal border. It provides a defined transition between the appliance and the surrounding wall or mantel rather than changing the fireplace’s size or operating system.
Its outer dimensions are 38 × 29.67 inches, with a 1.57-inch depth. Check those measurements against the exact firebox and finished wall; the outer trim dimensions are separate from the fireplace’s framed opening.
The trim is factory-preassembled with a bottom section that is retained for raised installations or removed for the floor-level arrangement described in the guide. Select the installation method before the surrounding finish is complete.
Measure the finish. Match the firebox.
Match RBF30TRIM38 to the documented RBF30 firebox family and check the actual opening and finished wall before ordering.

Let’s get your project right.
Does the trim’s width tell me which fireplace it fits?
No. RBF30TRIM38 is the 38-inch outer-width trim for the 30-inch RBF30 Revillusion firebox family. The trim width, firebox size and framed opening are different measurements. Match the full firebox model before comparing how much surrounding wall the trim covers.
Can I use this on any newer fireplace with the Revillusion name?
The assembly guide covers RBF30TRIM38 and the matching RBF trim series. A shared brand name or nominal 30-inch size alone does not verify a different REV or RBF model. Confirm the complete appliance label and current installation resource before treating this as a universal Revillusion trim.
How large is the finished outside edge?
RBF30TRIM38 measures 38 inches wide, 29.67 inches high and 1.57 inches deep in the manufacturer’s accessory specifications. Those are trim dimensions, not the required fireplace opening or a guarantee of how much an irregular opening will be concealed. Compare the actual wall surface, firebox position and drawing before ordering.
Should the bottom trim stay on a raised installation?
Yes. The assembly guide says the bottom trim is required when the firebox is installed in an elevated location. For a floor-level installation, the guide describes removing it. Choose that arrangement before fitting the trim and follow the complete assembly sequence rather than buying an additional lower piece.
Does the trim arrive assembled, or as loose border pieces?
The guide describes a factory-preassembled trim with the optional bottom trim already present. It identifies four supplied assembly screws. Removing the bottom trim involves the fasteners shown in the guide; do not confuse those preinstalled screws with a separate retail hardware pack.
Is the installation method the same for a retrofit and new construction?
The guide gives different methods for an existing opening and new construction. One arrangement secures the trim to the firebox; another considers fixing the firebox and trim to the wall or framing. Choose the applicable method with the installer, including suitable fixings for the supporting material.
Can the trim replace structural support or hide an unsuitable opening?
The trim is a finishing accessory. It does not make an unsupported firebox safe, establish a new appliance clearance or replace the firebox’s framing requirements. Resolve support, fit, power access and the surrounding finish using the appliance and trim instructions before closing the wall.
Will I need to access the fireplace’s interior during fitting?
The assembly sequence includes temporarily removing and then reinstalling the firebox’s inner decorative panels. Plan access to the appliance and protect the finish while working. Use the exact guide and disconnect power as required by the appliance instructions; the trim is not simply an adhesive border stuck over the wall.
Should I order both trim widths for the same firebox?
The widths grouped on this page are alternative finishing choices for the documented firebox size. Choose the appropriate outer coverage and installation arrangement; they are not pieces that combine into a larger trim. Switching a width option also changes the exact accessory SKU and its dimensions.
What should I have ready when asking for fit or warranty support?
Keep RBF30TRIM38, the firebox’s full model number, measured opening and surrounding finish, and your purchase record. The exact assembly guide is linked below. This separate trim does not inherit the firebox’s electrical ratings, heat output or appliance warranty period; use the terms applicable to the accessory purchase.
CONFIDENCE BEYOND THE FIRST FIRE
The right fit. The right support.
Keep the trim model, full firebox model and purchase record together for fit and accessory support. The linked trim guide explains the supported installation methods; appliance warranty periods should not be assumed to cover a separate accessory.
