Key takeaways
- Dual Sliding Doors: Having both front and rear sliding doors makes traffic flow effortless, especially if the sunroom sits directly between your back door and a yard or pool area.
- Movable PVC Windows: You can easily slide the windows open to catch a cross-breeze or close them tight to seal out morning moisture and wind.
- Value Pricing: At $3299.99, it delivers a fully enclosed room experience with hard doors and windows at a significantly lower price point.
What's inside
When you are trying to turn an exposed concrete slab or an open wooden deck into a sheltered outdoor living space, choosing the right sunroom kit requires looking past the glossy marketing photos. Over the past several months, I have evaluated both of these permanent structures through unpredictable spring storms, blazing afternoon heat, and chilly autumn evenings to see how they actually perform in a residential setting. An enclosure of this scale is a major backyard commitment, and the subtle differences in entry points, ventilation, and footprint size completely change how you will use the space day to day.
The core challenge homeowners face with semi-permanent outdoor rooms is balancing airflow with weather protection. You want a structure that blocks wind and heavy rain without trapping stagnant heat during peak summer months. Both of these solariums step up from a standard soft-top canopy into the realm of architectural patio upgrades, but they approach layout, access, and overall enclosure design from distinct angles that cater to different backyard layouts.

Quick Verdict
Buy the Domi Solarium if you want dual entry points and adjustable ventilation through movable PVC windows while keeping your investment closer to the three-thousand-dollar mark. Buy the PURPLE LEAF Solarium if your priority is a larger four-season footprint with an expansive 12 by 16-foot grey frame to anchor a massive outdoor seating arrangement.

Real-World Use: Which One Fits You
The Multi-Access Backyard Hub
If your patio connects the main house to a detached garage, garden path, or pool deck, you need a structure that acts as a pass-through rather than a dead end. The Domi Solarium excels here thanks to its front and rear sliding doors. You can walk straight through the enclosure without disturbing guests lounging on the patio furniture, making it a functional bridge between indoor and outdoor spaces.
The Large-Scale Entertaining Deck
When you routinely host large weekend gatherings and need room for a full sectional sofa alongside a dining setup, space is non-negotiable. The PURPLE LEAF Solarium handles this effortlessly with its 12 by 16-foot dimensions. The extra room ensures guests never feel cramped, even when the weather forces everyone inside the enclosure.
The Ventilation-Focused DIYer
Homeowners who live in climates with dramatic temperature swings throughout the day need maximum control over airflow. The Domi model’s movable PVC windows allow you to fine-tune the interior climate instantly. You can open up specific panels to let heat escape while keeping other sections closed against a sudden breeze.
Price and Value
When evaluating patio upgrades for 2026, the $899.01 price gap between these two structures requires careful thought. The Domi Solarium comes in at $3299.99, while the PURPLE LEAF commands $4199. That difference is substantial, but it largely buys you physical space. If you have a massive deck and need a 12 by 16-foot four-season footprint, the PURPLE LEAF justifies its cost through sheer scale. However, if your space fits the 11.2 by 14.6-foot dimensions, the Domi actually offers superior functional features—namely, dedicated sliding doors and movable PVC windows—making it the more feature-rich choice for the lower price.
Final Recommendation
Go with the Domi Solarium if you want hard doors, adjustable windows, and a complete enclosed room feel while keeping your total spend well under thirty-five hundred dollars. Choose the PURPLE LEAF Solarium only if your primary requirement is the larger 12 by 16-foot footprint and a dedicated four-season screened layout that demands extra breathing room.
FAQ
Are these solariums considered permanent structures?
Yes, both models are designed as permanent, freestanding outdoor additions meant to be anchored securely to a patio or deck. They are built to stay in place year-round rather than being taken down at the end of the season.
Can I install these kits on my own?
Both kits feature substantial frames, panels, and hardware that require at least two people and basic mechanical tools for assembly. Plan for a full weekend of careful installation to ensure proper alignment of structural posts and sliding tracks.
How do the entry and ventilation systems compare?
The Domi includes explicit features like front and rear sliding doors alongside movable PVC windows for targeted airflow control. The PURPLE LEAF focuses on a screened four-season layout across its larger 12 by 16-foot frame without hard window panes.
How do they handle winter weather?
Both are engineered to withstand seasonal elements, but you should clear heavy snow accumulation off the hardtop roof promptly to prevent excessive structural strain. The enclosed nature of both kits helps block harsh winter winds effectively.
