The Finishing Touch Sauna Shield — Sauna Timber Protection Oil 500ml
Sauna Shield is a high-quality, professional-grade timber oil formulated to protect and nourish sauna benches and panels. The intense heat and moisture of a sauna dries timber out and leads to splitting and cracking. Sauna Shield forms a barrier that keeps the timber in peak condition for years to come.
- Physically Stocked, unlike most "drop-shipping" websites.
- Shipped from VIC, NSW, WA, QLD
Ensure the sauna is turned off and the timber is dry before applying.
Why Choose Sauna Shield?
- Moisture protection — forms a durable, invisible barrier that defends wood against moisture, heat and wear.
- Timber restoration — deepens the natural tone of the wood and enhances the grain and glow.
- Damage prevention — designed to help prevent the splitting and cracking caused by regular sauna use.
- Heat resistant — a colourless oil suited to the high-heat environment of traditional and infrared saunas.
- Safe and skin-friendly — fragrance-free, solvent-free and toxin-free.
- Effortless application — trigger spray for easy, even coverage across all timber surfaces.

Sauna Shield FAQs
How often should Sauna Shield be applied in a personal sauna?
Apply Sauna Shield to a new sauna installation after cleaning with Sauna Shine. Reapplication depends on usage — apply when the wood starts to look dull, or every 3 to 6 months to maintain protection.
How often should Sauna Shield be applied in a commercial sauna?
Depending on usage, every 1 to 3 months. The wood will start to look dull and sweat, and water will begin absorbing into the timber, when it is due to be oiled.
How long do I need to wait before using the sauna after applying Sauna Shield?
Let it absorb into the wood, wipe off any excess, and wait 30 to 60 minutes until dry before using the sauna.
Can I apply Sauna Shield too often?
Yes. Sauna Shield should absorb into the wood — over-application can leave the surface feeling greasy or uneven.
Should I apply Sauna Shield to a new sauna before using it?
Yes. Clean with Sauna Shine first, then apply Sauna Shield to protect the timber from first use.
Can I use Sauna Shield in an infrared sauna?
Yes. Sauna Shield is suitable for both traditional and infrared saunas.
Is Sauna Shield safe to use on heated surfaces?
Avoid spraying heater elements or electrical components. Apply to timber surfaces only.
Is this product safe for regular weekly use?
Sauna Shine can be used weekly for cleaning. Sauna Shield should not need weekly use — it is designed for longer-term timber protection rather than frequent application.
Always confirm with your sauna manufacturer to ensure compatibility. Contact us if unsure.

In plumbing, named sizes are not the actual measurements. A pipe called “50mm” or “2"” does not measure 50 mm across. Instead, it follows nominal sizing, an internationally-standardised naming system.
Use the Outside Diameter (OD) to check your pipe against fittings. Below is a quick reference for common spa & pool pipe sizes:
| Imperial Name | Metric Name | Pipe Diameter (OD) |
|---|---|---|
| 1/2" | 15mm | ~21.2–21.5 mm |
| 3/4" | 20mm | ~26.6–26.9 mm |
| 1" | 25 mm | ~33.4–33.7 mm |
| 1.5" | 40 mm | ~48.1–48.4 mm |
| 2" | 50 mm | ~60.2–60.8 mm |
| 2.5" | 65 mm | ~75.2–75.5 mm |
These are nominal sizes and are designed to fit matching fittings — not to measure exactly what their name suggests. These are based on PVC Pressure Pipe AS/NZ 1477 Dimensions1.
- º Internal diameters vary slightly by manufacturer and class.
- 1 Not all pool/spa fittings match these dimensions exactly. Some do not follow Australian or international standards. Chinese spas may use proprietary fittings.
Understanding Plumbing Sizes & Nominal Measurements
Plumbing sizes can be confusing. PVC and many other pipe systems use nominal sizes—the size is a name, not the exact measured dimension. This convention is used across most pool and spa systems so that pipes and fittings remain compatible.
Why pipe sizes don’t match the measurements
The Nominal Pipe Size (NPS) system standardises pipe dimensions so that pipes, fittings, valves, and accessories interoperate. Plumbers work with these nominal names every day, but DIYers can be tripped up if they try to match by a tape-measure alone.
How to Measure Pipe Correctly
-
Pipe size is identified by:
- The pipe’s Outside Diameter (OD).
- The fitting’s Inside Diameter (ID) (socket opening).
- Pipe Class / Schedule (e.g., Class 9, 12, 18 or Sch 40) relates to wall thickness and therefore the Internal Diameter (ID) and pressure rating.
- The outside diameter of a fitting is not useful (wall thickness varies by manufacturer).
Hose & Tube Dimensions
Common flexible hose sizes used in pool/spa systems (approximate IDs).
| Imperial Name | Metric Name | Inside Diameter (ID) |
|---|---|---|
| 3/8" | 9–10 mm | ~9 mm |
| 3/4" | 19 mm | ~19 mm |
BSP – British Standard Pipe Thread Sizes
BSP thread names are also nominal. The thread OD will not equal the nominal name.
| BSP Thread Size Naming | Outside Diameter (mm / inch) | TPI |
|---|---|---|
| 1/16" BSP | 7.7 mm / 0.304" | 28 |
| 1/8" BSP | 9.7 mm / 0.383" | 28 |
| 1/4" BSP | 13.16 mm / 0.518" | 19 |
| 3/8" BSP | 16.66 mm / 0.656" | 19 |
| 1/2" BSP / 15 mm | 20.99 mm / 0.825" | 14 |
| 5/8" BSP | 22.99 mm / 0.902" | 14 |
| 3/4" BSP / 20 mm | 26.44 mm / 1.041" | 14 |
| 7/8" BSP | 30.20 mm / 1.189" | 14 |
| 1" BSP / 25 mm | 33.25 mm / 1.309" | 11 |
| 1-1/4" BSP | 41.91 mm / 1.650" | 11 |
| 1-1/2" BSP / 40 mm | 47.80 mm / 1.882" | 11 |
| 2" BSP / 50 mm | 59.61 mm / 2.347" | 11 |
| 2-1/4" BSP | 65.71 mm / 2.587" | 11 |
| 2-1/2" BSP | 75.18 mm / 2.960" | 11 |
| 3" BSP | 87.88 mm / 3.460" | 11 |
| 4" BSP | 113.03 mm / 4.450" | 11 |
| 5" BSP | 138.43 mm / 5.450" | 11 |
