The Mt. Rainier GardenHouse kits maximize your greenhouse experience. Standing very nearly ten feet tall at the peak and eight feet wide, there is plenty of room for growing and relaxing. Each Mt. Rainier Model is made with a clear natural redwood frame, twin wall polycarbonate and roof vents. Choose a Dutch door (28" wide x 78" tall) with rear wall vents or 2 Dutch Doors and no rear wall vent. Also available with an optional wheelchair accessible door that is 39″ wide. The base is made of non-decaying recycled plastic and comes standard with each greenhouse. With up to four optional benches, you can optimize your space. With our pre-assembled panels, you can easily assemble your Mt. Rainier series GardenHouse in one to two days. Also available with an optional wheelchair accessible door that is 39″ wide. Each GardenHouse includes easy-to-follow printed instructions, clearly labeled panels, and an excellent assembly video.


Automatic Vents Simplify Climate Control

Automatic vent operators on the roof and base vents require no electricity or batteries. The vent operator contains a paraffin (wax) that expands when the temperature reaches about 65°F, pushing the vent open to its fully opened position at about 85°F. As it cools and the paraffin contracts, the operator’s springs draw each vent closed. It is adjustable within approximately 5°F and easily detachable for manual operation.

Redwood Bench Kits

Specially designed matching redwood benches are available that run the full length of the Sunshine GardenHouse.. Benches are 21″ deep for all Mt. Hood models. Mt. Rainier models are 31″ deep or 21" deep if you choose the 39" Fully Accessible Door option. Up to 4 benches can be used in each GardenHouse.

Anchor Kits

Sunshine GardenHouses are heavier than most greenhouses, but we still recommend an anchor system for use where a GardenHouse is exposed to winds or storm activity. For installations on soil foundations, we offer the inexpensive, easy to install and very sturdy Sunshine Anchoring System. This system includes four 1/2 inch diameter x 16 inch rebar ribbed steel stakes and two cold galvanized anchor base plates—you just hammer the anchors into the soil. We suggest using two anchors per side on the 8 x 8 and 8 x 12 Mt. Rainier, a total of 4 sets. For the 8 x 16 we suggest three anchors on the long sides and 2 anchors on the ends, a total of 5 sets.

Accessible Door Option

39″ Fully Accessible Door (shown on 8′ x 16 above) for 8 x 12 and 8 x 16 models. NOTE: If you order the accessible door AND benches, you MUST order the 21" benches.

    Great greenhouse!

    Posted by Edward K. on Feb 7th 2018

    Hobby Greenhouse Growers...thank you! You have the best price online for the Sunshine gardenhouses, and great customer service, and delivery was right on time with no problems. Free shipping was great! Pros: great product, good instructons, booklet and DVD, everything labeled clearly, highly recommend. Cons: none that I have. This is my 2nd greenhouse, and it far surpasses the cheap metal-framed one I bought 2 years ago that is now in some garbage dump. I am so pleased!
