Optional Extras

Integral Staging

Attaches with brackets to the frame down the full length of the greenhouse, for sturdy staging that leaves floorspace free of osbstruction. Our 2ft integral is ideal for use as a work bench and is the correct depth for our potting pal, while our 1ft integral is perfect for seedtrays and general storage.

Enhanced Ventilation

Have greater environmental control with the addition of further vents and solar-powered automatic openers.

Rainwater Collection

Every Rhino is fitted with gutters and 2 downpipes as standard. A conversion kit or "2-into-1" kit, brings the flow of 2 outlets into 1 so that only 1 water butt is needed. Learn more

Other Staging

Free-standing potting tables and other staging accessories to help make your gardening more fun and efficient. Learn more

Shelves and Seedracks

Seedracks are an essential space-saver for autumn and spring sowing. (Please note seedracks and trays are sold separately.) Our 10" slatted shelving is a great way to add further storage; we recommend installing at the gable end, leaving at least 1ft of space to either side so that there is adequate support for the shelf. For example, an 8ft wide greenhouse could accommodate a 6ft wide shelf at most. Learn More


Patented Rhino blinds technology is specifically designed for Rhino greenhouses. Fits easily to the ridges and integral gutters for full external coverage of roof and side panes. Read more

What's Included
Meet the Makers

You’ll love having a Rhino in your garden, it’s the perfect environment for your plants and looks beautiful.

It’s also very strong and safe for you and your family. We care about quality. We design and manufacture the Rhino in our own UK factory and sell direct to the public. We think this makes the Rhino the best value greenhouse money can buy. See what you think.

Louvre Vents & Automatic Roof Ventilation

Included as standard with the Rhino Classic 6x12 greenhouse:

  • 4 Single Roof Vents
  • 2 Side Louvre Vents
  • 4 Automatic Roof Vent Openers

This amounts to 22sq ft - 37% of the floor area of the greenhouse.

Each Rhino Classic includes a much larger ventilated area than other greenhouses in its class. All the roof vents are controlled by solar-powered automatic vent openers

The high quality Rhino five-blade louvre vents allow you to take complete control of your ventilation, allowing cool air to enter from the side, circulate up through the greenhouse forcing air to escape through the roof vents. Optimal circulation can only be achieved through a combination of roof vents and side louvres.

Adequate ventilation is absolutely crucial to successful growing under glass. There is not another greenhouse on the market that has more ventilation than a Rhino. Better still, it's all included in the price.

4mm Toughened Glass - strong and safe

Keep yourself and your family safe with Rhino's combination glazing system: Toughened Safety Glass and Rubber Glazing Beads. Perfect for exposed locations and families with young children and pets.

Rhino Tuff 4mm toughened safety glass is 33% thicker than most greenhouse glass and comes as standard with every Rhino greenhouse. The panes are designed with safety in mind, meaning breakages are less likely while ensuring that, if broken, the glass will shatter into lots of tiny pieces rather than big shards that are far more likely to cause injury. Even the edges of the glass are rounded so that you don’t cut yourself during installation. And with Grade A glass, you can achive ultimate clarity for maximum light.

The unique Rhino glazing system locks each pane of glass in place along its entire length, using long rubber beads. The glass cannot be blown or sucked out of the frame and pushing on the glass only locks the beads more tightly into the frame, making it ideally engineered for high winds and other extreme weather conditions. With Rhino's glazing method, each pane becomes integral to the strength of the whole frame.

When compared with the glazing that comes as standard on most greenhouses, the Rhino ranges come up trumps every time. No dangerous horticultural glass or flimsy W-clips here; and with the smooth finish achieved by our glazing beads, there's no need for bar capping either.

Strong Frame - great wind resistance

We wouldn’t sit on the roof if a Rhino wasn’t so strong! Indeed, it’s why we named them Rhino. Every single Rhino is engineered for strength and stability, making it perfectly adapted for extreme weather and exposed locations - many customers choose a Rhino specifically for this reason, and often hear that they have withstood storms and very strong gales (up to 137mph, so far). Whether you're in the Outer Hebrides or the Channel Islands, our Rhinos make secure growing locations, no matter the weather.

Each Rhino frame has around 60% more aluminium than similarly priced models. But it’s not just the weight, it’s the clever design of the Rhino that provides its inherent strength. There are 3 key factors that contribute the strength of the Rhino range, creating a solid and airtight framework from the top of the roof to the ground

  1. Strong tubular bracing
  2. An integral base
  3. The Rhino Tuff glazing system

We’ve tested the snow loading capacity of a Rhino by putting half a tonne of sand bags on the roof, so she’s ready for whatever the Great British weather may throw at her.

Integral Base – stronger and great access

Every Rhino greenhouse includes a strong aluminium base in the price, which not only provides an incredibly strong foundation but also allows the Rhino to be erected simply onto firm, level soil – so there’s no need for an expensive concrete base. Once the Rhino is erected, strong stainless steel ground anchors are concreted into position.

The Rhino can also be erected onto a hardstanding of concrete or paving slabs, in which case the stainless steel anchors are fixed using the expansion bolts provided.

Our 2017 models also have a low-threshold entrance and comes with a stainless steel ramp included, removing trip hazards entirely. This also makes the greenhouse accessible for wheelchair users and wheelbarrows. 

Hanging Basket Rails

Every Rhino greenhouse comes with two hanging basket rails.

The roof is so strong that it can easily handle this extra load, and it’s a really useful feature. Your hanging baskets will thrive and it will also free up lots of space on your staging.

Rainwater Collection

Every Rhino greenhouse also comes with large integral gutters as well as downpipes and bends so you can collect and use the natural rainwater that your plants love.

There is an optional two-in-one kit available at an extra cost which joins the two pipes at the rear of the greenhouse and allows both gutters to feed into one water butt.

25 Year Guarantee – they're that good

Nothing says more about the quality of a Rhino greenhouse than our 25 Year Guarantee.

A generation of gardeners can rest assured that the frame and even the powder coated colour finish are covered, in the unlikely event that the greenhouse fails.

Every Rhino greenhouse is delivered with a comprehensive set of instructions. With help at key moments, a competent DIY enthusiast can erect this size of greenhouse over a weekend. 

However, this time and effort can be eliminated by using a professional installer who will quickly and efficiently erect, glaze and anchor down the greenhouse on your pre-prepared site – either soil or hardstanding. See our Guidance Notes on Site and Base Preparation and Installation.   

Installer charges for this size (depending on location and exact specification) are from £290. 

Add this to your order and we will contact you to confirm a quote.

Once you've placed an order, we will send you relevant details for independent installers local to you, should you wish you to pursue this.
