Sunrooms with fireplaces offer the perfect blend of indoor comfort and outdoor ambiance, transforming a simple glass-enclosed space into a cozy retreat that can be enjoyed year-round. From traditional wood-burning hearths that evoke rustic charm to sleek, modern gas inserts that blend seamlessly into minimalist aesthetics, there is a fireplace style to suit every sunroom design. Key considerations include the choice of materials—stone, brick, tile, or shiplap—the placement within the room for optimal heat distribution and sightlines, and the integration of built-in seating or storage to maximize functionality. Whether you aim for a classic look or a contemporary statement piece, these twenty ideas will inspire you to create a sunroom that’s as warm as it is bright.
1. Floor-to-Ceiling Stone Fireplace

A floor-to-ceiling stone fireplace anchors the sunroom with natural texture and earthy warmth, creating a dramatic focal point that complements abundant glazing. The rugged stone extends from the hearth all the way to the ceiling, visually connecting the indoor space with the surrounding landscape and emphasizing the room’s verticality. Stone varieties such as limestone, slate, or river rock can be chosen to echo exterior finishes or interior accents, ensuring cohesion with the overall home design.
2. Modern Linear Gas Insert

A sleek linear gas insert offers clean lines and efficient heat output, perfect for contemporary sunrooms with minimalist décor. Mounted within a smooth plaster or concrete wall, the flame appears to float, enhancing the airy feel of the glass-enclosed space. These inserts often include remote controls and adjustable flame settings, allowing homeowners to tailor ambiance without compromising on style.
3. Rustic Brick Hearth

Embrace farmhouse charm with a rustic brick hearth that adds warmth and character to a sunroom. Exposed brick, either reclaimed or new, can frame a traditional wood-burning stove or open fireplace, infusing the space with a timeless, lived-in appeal. Pair with distressed wood beams and wrought-iron accents to complete the cozy cottage vibe.
4. Corner Fireplace for Space Efficiency

Installing a fireplace in the corner maximizes floor space and offers dual seating sightlines in an L-shaped sunroom layout. Whether you choose a masonry build or a prefabricated insert, corner placement can visually widen the room and provide balanced warmth on both sides. Opt for a hearth that blends with built-in benches or shelving to create a cohesive, multi-functional design.
5. Double-Sided Fireplace

A double-sided fireplace serves two adjacent spaces—such as a sunroom and living room—simultaneously, allowing the fire’s glow to be enjoyed from both areas. Transparent glass on either side showcases dancing flames while maintaining an open flow between rooms. This design not only distributes heat efficiently but also amplifies natural light by reflecting it off the glass surfaces.
6. Suspended Bubble Fireplace

For a daring, sculptural statement, consider a suspended bubble fireplace hung from the ceiling. Its rounded, cocoon-like form offers 360° views of the fire, creating an intimate gathering point in the center of a sunroom. The floating installation accentuates ceiling height and adds a futuristic edge to an otherwise traditional glass-paneled enclosure.
7. Built-In Seating and Hearth

Combine the hearth with built-in bench seating to maximize functionality while framing the fireplace feature. Upholstered cushions on the bench soften hard edges and invite cozy lounging, making this design ideal for sunrooms used as reading nooks or conversation areas. Storage drawers beneath the seating can stow firewood or seasonal décor, keeping the space clutter-free.
8. Electric Fireplace Wall

An electric fireplace embedded within a feature wall offers flawless integration and minimal installation requirements, making it a versatile choice for retrofits. With realistic embers and flame effects, these units deliver warmth on demand without a chimney or vent, preserving glazing for uninterrupted views. Surround the insert with shiplap or tile to add texture and style.
9. Sunken Seating Around Hearth

A sunken seating area surrounding a central hearth creates a convivial, terraced gathering spot reminiscent of ancient fire pits. The lowered floor plane enhances sociability by bringing occupants closer to the fire’s warmth and each other, fostering intimate conversations in the bright sunroom setting. Slip-resistant materials ensure safety while maintaining visual continuity with the rest of the flooring.
10. Marble Mantel and Surround

For an air of sophistication, frame the fireplace with a polished marble mantel and surround. White or Carrara marble pairs beautifully with glass walls, reflecting natural light and elevating the sunroom’s refined aesthetic. Contrasting dark hearth tiles or a black insert can add depth and drama against the bright stone.
11. Fireplace and Skylight Combo

Integrate a skylight directly above the fireplace to marry flickering flames with natural sunlight, creating a dynamic interplay of light throughout the day. This combination amplifies the open-air feel of the sunroom while drawing attention upward, emphasizing architectural height and volume. Ensure proper flashing and insulation around the skylight for weatherproofing and energy efficiency.
12. Colorful Tile Surround

A boldly patterned or colorful tile surround injects personality and visual interest, transforming the fireplace into an artistic focal point. Moroccan zellige or encaustic cement tiles offer handcrafted appeal, while geometric porcelain tiles provide a contemporary twist. Coordinate with throw pillows or area rugs in complementary hues to tie the palette together.
13. Wood-Burning Stove Style

Embrace vintage charm with a freestanding, cast-iron wood-burning stove set on a tiled hearth. Its compact footprint and efficient burn make it an ideal choice for smaller sunrooms, delivering cozy heat and nostalgic ambiance. Place on a raised platform to prevent heat damage to flooring and to enhance visibility of the dancing flames.
14. Gas Log Fireplace in Brick Nook

Nestle a gas log fireplace within a recess framed by painted brick for a blend of traditional texture and modern convenience. The gas insert offers instant warmth, while the brick backdrop adds tactile depth and a timeless cottage feel that complements natural light. Installing adjustable vents in the niche ensures optimal airflow for efficient combustion.
15. Two-Tone Fireplace Surround

Combine contrasting materials—such as a smooth concrete surround atop a reclaimed wood base—for a two-tone fireplace feature that feels both industrial and warm. The juxtaposition highlights textural richness and underscores the sunroom’s dual nature as an indoor-outdoor living space. Accent with metal-framed windows or black hardware to echo the industrial motif.
16. Built-In Planters Flanking Hearth

Softening the hearth’s hard edges, built-in planters on either side introduce greenery that thrives in sunlit spaces. Pothos, ferns, or succulents provide lush foliage year-round, enhancing the connection to the outdoors while the fireplace maintains seasonal warmth. Waterproof planter liners and integrated drainage protect the surrounding flooring and structure.
17. Coastal Whitewashed Fireplace

Whitewash brick or stone for a breezy, coastal-inspired sunroom that feels bright and airy. The light finish reflects sunlight and highlights the texture of the masonry, while driftwood mirrors and nautical accents complete the seaside vibe. A simple mantel shelf can display shells or seaside finds for a personalized touch.
18. Eclectic Bohemian Hearth

Layer an eclectic mix of global textiles, patterned rugs, and artisan pottery around a simple fireplace to cultivate a bohemian retreat. Macramé wall hangings above the mantel and colorful floor cushions invite laid-back lounging, while the fire’s glow adds warmth and intimacy. Mismatched furniture pieces emphasize relaxed, collected-over-time charm.
19. Scandinavian Minimalist Fireplace

Embody Scandinavian minimalism with a pared-down fireplace design featuring clean white plaster walls and light ash wood accents. The unobtrusive hearth complements simple furnishings and large glass panes, fostering a serene, uncluttered atmosphere focused on natural light and functional beauty. A single potted plant or wool throw adds cozy texture without overwhelming the space.
20. Industrial Steel Frame Insert

Highlight the industrial aesthetic by installing a steel-framed fireplace insert with visible rivets or welded seams. Paired with concrete or brick walls, the metallic finish underscores raw, urban character, while the fire’s warmth balances the cool materials for a stylish contrast. Blackened steel mantels or overhead beams can reinforce the loft-style ambiance.
Conclusion:
From timeless stone hearths to avant-garde suspended designs, integrating a fireplace into a sunroom elevates the space from a mere glass enclosure to a warm, welcoming haven. By carefully selecting materials, placement, and accompanying décor—from built-in seating and planters to bold tile or minimalist finishes—you can tailor the fireplace to reflect your personal style and architectural context. Whether your vision leans rustic, modern, coastal, or eclectic, these twenty ideas demonstrate the versatility of fireplaces in enhancing both the form and function of your sunroom, ensuring comfort and inspiration in every season.
