LOSP pine stair kit
A treated pine kit for your stair enquiry. Choose the tread count and width, then send your measurements for confirmation.
The stair kit collection
DIY Timber Stairs is your specialist starting point for outdoor timber stair kits. Compare LOSP pine, Merbau and premium ranges, select your tread count and width, then add it to your quote. Your request starts a conversation; the final dimensions and included components are confirmed before supply.
LOSP pine and Merbau identify material choices. Premium describes a configuration to discuss alongside the timber, rather than another timber species. Choose a starting point, then confirm the actual components for your measured flight.
| Enquiry route | What it identifies | Confirm in your quote |
|---|---|---|
| LOSP pine kit | Treated-pine range | Material dimensions, treatment specification and finish requirements |
| Merbau kit | Merbau timber range | Material dimensions, grade and finish requirements |
| Premium kit | Premium configuration enquiry | Material choice, tread detail and supplied components |
| Internal stair | Stair for an indoor project | Layout, material, finished floor levels and scope |
Board depth and going are different dimensions. Confirm horizontal spacing between nosings, width endpoints and the upper landing arrangement for the kit you will actually order.

The standard enquiry selector offers 1–17 separate treads, calculated at 165 mm per rise. With the upper landing as the final walking surface, this means 2–18 risers and an indicative total rise of 330–2,970 mm. These choices describe an enquiry, not stock availability. Select Custom for your actual measured height.
The width field records your requested dimension; it is not a list of manufactured sizes. Label whether it means tread length, clear walking width or outside-to-outside width. Confirm the going, board depth, thickness, nosing and any centre supports before ordering. See the complete rise table and labelled stair diagram.
| Detail | What to record or confirm |
|---|---|
| Geometry | Finished total rise, riser and tread counts, individual rise, going and horizontal projection. |
| Timber and dimensions | Timber, treatment where applicable, section sizes, tread profile, nosing and clearly labelled width. |
| Supply and assembly | Complete kit or components; assembled or flat pack; exact treads, stringers, supports and fixings included. |
| Price and timing | Current written price, GST treatment, quote validity, production lead time and any finish work. |
| Delivery | Destination postcode, freight cost, access, unloading arrangements and agreed dispatch or collection timing. |
Before assembly, reconcile the supplied parts and drawings with your approved specification. Have the installer confirm supports, connections, finished levels and site conditions. Follow the instructions supplied for your actual kit, including any timber treatment or finishing requirements. Our installation planning guide is a preparation checklist; it does not replace current product instructions or a site-specific design.
Check the applicable building requirements with your building surveyor or relevant practitioner. Stair geometry alone does not assess structural loads, landings, headroom, barriers, handrails or slip resistance. The Victorian regulator explains stair and barrier structural documentation. Requirements depend on the building, jurisdiction and applicable code edition.
