How much does a greenhouse cost? Real 2026 kit prices

Here is the honest range, from the US pages we read on November 12, 2026. At the bottom, the Outsunny 6x8 was $381.99 and the Outsunny 8x16 $595.99 at Aosom. In the middle, Palram-Canopia's 6x8 kits were $889 (Mythos) and $899 (Hybrid), and its 8x12 kits ran from $1,899 (Essence) to $4,349 (Glory) at Planet Greenhouse. The steel tunnels from YourGreenhouses and Bloomcabin sat between $2,765 and $3,372.97. At the top, the glass Scandiglas was $6,999, already a Black Friday price against $11,699 listed.

So the short version: under $1,000 buys you a small greenhouse, $1,900 to $3,400 buys a real walk-in one you won't outgrow, and above that you are paying for thicker panels, glass or a premium frame.

Headline prices hide the most useful comparison. Divide the price by the floor area and the ranking changes completely. On our list, the Outsunny 8x16 works out at about $4.54 per square foot, the Palram Mythos at about $18, the Essence at about $20, the YourGreenhouses Polycarbonate at about $21.60, the Glory at about $45 and the Scandiglas at about $72.

A low number is not automatically a good deal. The cheapest kits publish low or no snow and wind ratings and no warranty term. But price per square foot is the fairest way to compare a 6x8 with a 10x13, and it is why it carries 20% of our score. It also shows where your money goes: past about $25 per square foot, you are buying thicker panels, taller frames and longer warranties, not more space.

This is where budgets go wrong. Some kits come complete; others leave out things you will want in the first week. Real examples from the pages we read:

• Roof vents on the YourGreenhouses tunnels: $95 each. In a sunny climate, budget for at least one.
• An automatic roof-window opener for the Scandiglas: $139.
• Palram's anchor kit for the Snap & Grow: $129 at Planet Greenhouse, because no base is listed.
• The Rion base kit for the Grand Gardener: $469, or your own concrete pad or timber frame.
• A lifetime warranty add-on for the YourGreenhouses kits: $260.

By contrast, the Palram Glory includes two automatic vent openers, a louver, a steel base and anchors, and the Essence, Mythos, Hybrid and Balance include a galvanized steel base. Compare complete costs, not sticker prices.

Then there is everything that isn't a kit part. A level base: pavers, a gravel pad with a timber frame, or a concrete slab (see our foundation guide). Benches and shelves. A thermometer, a watering can, a hose to reach it. Shade cloth for July and possibly a heater for January (our winter heating guide covers the options). None of these has to be expensive, but together they can add a few hundred dollars, so leave room for them.

Delivery is usually included at this level. Planet Greenhouse listed free curbside freight to the 48 contiguous states, YourGreenhouses free US shipping, and Bloomcabin curbside delivery. "Curbside" means the pallet stops at the curb: have a plan and a friend to carry the boxes in.

Grouped by size, the November 12, 2026, prices on our list look like this:

• 6x8 (about 49 to 52 sq ft): $381.99 for the Outsunny, $889 for the Palram Mythos and $899 for the Hybrid. The jump from $382 to $889 buys twin-wall panels, a published 15.4 lb/ft² snow rating instead of 8.19, and a 5-year warranty.
• 8x12 class (about 95 to 111 sq ft): $1,899 (Essence), $2,249 (Snap & Grow), $2,499 (Balance), $4,099 (Rion Grand Gardener), $4,349 (Glory) and $6,999 (Scandiglas glass).
• Tunnels from 106 to 131 sq ft: $595.99 (Outsunny 8x16), $2,765 (YourGreenhouses Polycarbonate), $2,810 (Arrow) and $3,372.97 (Bloomcabin High Tunnel).

Within each group, the spread is mostly panels, frame and what comes in the box. Read the review of any kit you are eyeing: each one lists the dated price, what is included and what is extra.

Start from your winters, not your wallet. If you only grow from spring to fall in a sheltered yard, a budget kit does the job, and the money saved buys seeds and soil. If you get frost, look for twin-wall panels: the $889 Mythos and the $1,899 Essence are the best value on our list. If you get real snow, the YourGreenhouses tunnels publish 32 to 38 psf for under $3,000, which is the smartest money in snow country.

And buy one size bigger than you think. Every greenhouse owner says the same thing a year later. Our size guide helps you pick, and the best kits under $2,000 ranking sorts the budget options.

If we had to spend our own money today: under $1,000, the Palram Mythos for its twin-wall panels and steel base. Under $2,000, the Palram Essence, which is the best value walk-in kit on the site. Under $3,000 in snow country, the YourGreenhouses Polycarbonate or the Arrow, with a roof vent added. And if money is no object and you want to grow all year, the Palram Glory, which needs nothing extra at all. The full greenhouse kit ranking shows where every kit lands.

Two pricing patterns are worth knowing. YourGreenhouses sells some kits as pre-orders, cheaper than in-stock units: on November 12, 2026, the 13 ft Polycarbonate was $2,765 on pre-order against $3,072.21 in stock, with delivery from mid-January. If you are planning for spring, that is free money. Others show a discount against a higher list price, like Bloomcabin's 45% off $6,132.67 or Aosom's sale prices. We always use the price you can actually pay on the day we check, and we date it, so you know how fresh it is.
