Dimplex Revillusion 24-inch
Opening & fit guide
The opening, depth and finishing details to settle before the surround is built.
The short answer
Measure the opening—not the name.
The Revillusion 24-inch firebox needs a framed opening 24 5/8 inches wide × 22 3/8 inches high × 12 1/2 inches deep. “24-inch” is the product’s size label, not a cutout instruction. Start with those three framing dimensions, then resolve the wall finish and power connection before construction.
Building a new surround?
Give the installer the firebox drawing before the framing is closed. The finished surround, the space behind the unit and the visible front all need to agree.
See the measurement guideUsing an existing opening?
Measure the narrowest width, lowest height and usable depth. A mantel opening that looks large enough from the room can still be too shallow behind the face.
Plan the openingSee what you are planning
Depth is part of the fireplace’s character.
Revillusion creates a traditional hearth composition: physical logs, a taller opening and an interior you can see into from the seating area. We would settle the front proportions and interior finish before spending time on decorative trim. A convincing finished fireplace depends on the surrounding wall as well as the appliance.
Choose the interior with the room in mind.
Black, brick and concrete-style interiors change the backdrop around the logs. This guide’s shopping link selects the 24-inch black-interior firebox; the range page lets you compare the other finishes.
Dimensions explained
Three measurements, three different jobs.
| Measurement | What to use | Why it matters |
|---|---|---|
| Framed opening | 24 5/8 W × 22 3/8 H × 12 1/2 D in | The opening prepared for the appliance. |
| Firebox body and front | The labeled firebox drawing in the manual | The front overlaps the opening; the outer front is not the rough opening. |
| Visible opening | The view of the logs and flame from the room | This is the proportion to balance against the mantel and furniture. |
| Power supply | 120 V | Choose the connection plan before the surround is finished. |

Depth deserves its own check.
Measure to the obstruction behind the opening, not simply to the back of the decorative mantel. Include the connection arrangement in the installer’s plan. The manual’s framing depth does not make a rear outlet or an obstruction disappear.

The Hearth Outpost view
Our take, and what owners say.
Revillusion 24-inch firebox
Ratings cover the Revillusion family.
We like this firebox when the room calls for a traditional hearth rather than a long horizontal flame. Its physical logs and taller proportions give the surround something substantial to frame. We would choose the interior finish and check usable depth early; a beautiful mantel cannot fix an opening that is too shallow.
What owners say
Owners often praise the realistic flames, appearance and straightforward installation. Mixed feedback mentions flame size, log proportions and operating noise; one owner also highlights the room needed behind the firebox for the plug.
Plan the opening
Work from the finished face backward.
The surround and the front
The manual calls for precise cuts in the finished surround. The self-trimming flange is a finishing detail, not a way to hide a poorly sized opening. The firebox front must not be recessed in a way that restricts heated-air flow.
The connection and the wall
The firebox can use its power cord or a hardwired connection. Have the installer settle access, circuit and routing before closing the wall. Do not plan around an extension cord.
Take a photograph straight on and one from each side of the proposed opening. Add the three measurements and the intended wall finish. That gives an installer a much clearer starting point than a product link alone. If a television or mantel is part of the project, include its placement requirements in the same plan.

Common questions
The details worth settling first.
Will any 24-inch opening work?
No. Use the 24 5/8 × 22 3/8 × 12 1/2-inch framed opening for this firebox, then check the full installation drawing and site conditions.
Can I use these measurements for the 30-inch Revillusion?
No. Other sizes need their own drawings. The range page has the available sizes; keep the selected size and its manual together.
Does the firebox need a chimney?
The built-in electric firebox does not require special venting. It still needs the air path, power arrangement and placement described in its instructions.
Is this the same as a plug-in Revillusion log set?
No. A built-in firebox and a log set are different appliances. If you intend to retain an existing fireplace, compare the relevant log-set instructions separately.
