About our 8ft wide plastic sheds

The Rubicon 8x10 is one current option. Check the models above for available sizes, prices and delivery details.

The Rubicon sits between our 6ft wide Skylight range and the 11ft wide Yukon range. At 2290mm wide, it offers genuine walk-in storage without dominating a medium-sized garden. We've assembled both models and the 10mm panels feel noticeably more solid than the standard Skylight panels.

Why We Chose This Range

"The Rubicon is the mid-range option I recommend most often. It's wider than the Skylight at 8ft but doesn't need the serious base preparation of an 11ft Yukon. The 10mm twin-wall polycarbonate is a step up from the standard panels, you can feel the difference in rigidity when you push against the wall. For customers who want more than a 6ft shed but don't have space for an 11ft Yukon, this is the answer."

Rubicon 8ft models compared

Rubicon 8x10

The 8x10 (£1,456) adds 750mm of extra depth for 7.0m² total. That extra space makes a real difference, you can fit shelving along the back wall and still have clear floor space in front. Same 2350mm ridge height and 1295mm door opening as the 8x8.

Matt's pick for 8ft wide sheds

Best For: Walk-in storage with room to organise

Why I Recommend It: The extra 2ft of depth on the 8x10 makes a bigger difference than the numbers suggest. I've fitted both models back to back, and the 8x10 feels like a proper room rather than a cupboard. You can stand inside, close the doors, and still move around your equipment.

Matt's Installation Tip: Rubicon Base Requirements

The Rubicon 8ft range needs a flat, solid base. We recommend paving slabs on a compacted hardcore sub-base for both models. The base should be exactly 2290mm x 2290mm for the 8x8 or 2290mm x 3040mm for the 8x10, the shed sits directly on the edges with no overhang.

Check your base is level across both diagonals before you start building. If the diagonals differ by more than 10mm, the doors won't close properly. We use a long spirit level and a straight edge across the full width. Spending an extra hour on the base saves hours of frustration later.

Both 8ft wide Rubicon sheds include free UK delivery, a heavy-duty built-in floor, and a 10-year warranty. They resist 75mph winds and won't rot, rust, or need painting. The dark grey colour blends well against fences and garden boundaries.

Want something smaller? Our 6ft wide plastic sheds start from £469. Need more space? The large plastic sheds page covers the full 11ft Yukon range from £1,991. See all options on our plastic sheds page.

Frequently Asked Questions

  • How much do 8ft wide plastic sheds cost?

    Prices vary by size; check the models above for current prices. Open the product page for its delivery details and included features.

  • What's the difference between Rubicon and Skylight sheds?

    Rubicon uses thicker 10mm twin-wall panels compared to Skylight's standard panels. The Rubicon is only available in dark grey and starts at 8ft wide, while the Skylight comes in grey and tan in 4ft and 6ft widths. The Rubicon feels more solid and provides better insulation due to the twin-wall construction. Both ranges use aluminium frames and require zero maintenance.

  • Can two people assemble a Rubicon 8ft shed?

    Yes, two people can build either model in 4-6 hours. The panels slide into the aluminium frame channels. You'll need a drill for the base anchors and a step ladder for the roof panels. We recommend assembling the floor frame first, checking it's perfectly level, then building up the walls before fitting the roof. No specialist tools are needed.

  • Should I choose the 8x8 or the 8x10?

    Choose the 8x10 if your garden has the space, the extra depth is worth it. The 8x8 gives 5.2m² which suits basic tool and bike storage. The 8x10 provides 7.0m², enough for shelving along the back wall and clear floor space in front. The price difference of around £386 buys 35% more usable area.

  • Are Rubicon sheds waterproof?

    Yes, the 10mm twin-wall panels and sealed aluminium frame keep water out. The panels slot into channels that prevent rain ingress at the joints. The floor sits on a raised frame that keeps moisture from wicking up from the ground. We've tested both models in heavy rain and found no leaks. The gable vents have screens that allow airflow while blocking rain.

  • Do I need planning permission for an 8ft wide shed?

    Generally no, under permitted development rules in England. The Rubicon's 2350mm ridge height is under the 2.5m limit for buildings within 2m of a boundary. This means you can place it close to a fence without planning permission in most cases. Check with your local authority if you're in a conservation area or your property has specific restrictions.
