About this range

The Tanalised Shed range

Tanalised Shed sheds are ideal for easy-maintenance, general-purpose, medium-duty outdoor storage. They provide a practical home for garden tools, equipment and other everyday outdoor items.

During tanalisation, the wooden framework is placed in a vacuum-sealed chamber. High-pressure wood treatment is then injected deep into the grain, helping to add years and years to the life of the shed.

We highly recommend this range where re-treating the timber would be difficult—for example, when the shed will sit in a corner or close to trees and shrubbery. It is an ideal trouble-free storage solution for gardens where access around the building may be limited.

Tanalised Shed sheds are ideal for:

Easy maintenance, general-purpose, medium-duty outdoor storage.

Comes with FREE ROT RESISTANT 'BEAST' FLOOR, FREE FITTING* & DELIVERY

Pressure treated for easier ownership

Treatment that penetrates deep into the timber

Tanalisation protects more than the surface. The timber is treated in a sealed chamber so preservative can be driven into the grain under high pressure.

01

Vacuum-sealed treatment

The timber framework is placed inside a sealed chamber as part of the treatment process.

02

Injected under high pressure

Wood treatment is forced deep into the grain rather than only coating the exposed surface.

03

Longer-lasting protection

The deep treatment helps add years to the useful life of your shed and makes ongoing care more straightforward.

04

Ideal for awkward access

A particularly useful choice where a corner, fence, trees or shrubbery will make later re-treatment difficult.

Tanalised Shed FAQs

Useful answers about pressure treatment, positioning and choosing the right shed for your garden.

Read all FAQs
What is tanalisation?

Tanalisation is a pressure-treatment process. Timber is placed in a vacuum-sealed chamber and preservative is injected deep into its grain under high pressure.

What is a Tanalised Shed best used for?

It is designed for easy-maintenance, general-purpose, medium-duty outdoor storage such as garden tools, equipment and everyday garden items.

Why choose this range for a hard-to-reach position?

The deep pressure treatment makes it a sensible choice where the shed will be close to a fence, in a corner or beside trees and shrubbery, making future access around the timber difficult.

Is a Tanalised Shed completely maintenance-free?

No timber building is entirely maintenance-free. Keep the shed clear of persistent vegetation and moisture, check the roof and fittings, and follow any care guidance supplied with your order. The pressure treatment is intended to make ongoing timber care easier.

How is this different from a dip-treated shed?

Dip treatment is applied to the timber surface. Tanalisation uses a sealed chamber and high pressure to carry treatment deeper into the wood grain, making it better suited to places that are difficult to re-treat.

Can I customise the size and layout?

Yes. Use the shed customiser to choose the footprint, layout and available options that suit your garden and storage requirements.
