Water appears inside your sauna after rain: document before repair

Water found after rain needs an evidence map before it needs a repair product. Record where the water was first noticed, what the weather and sauna were doing, and which surfaces were wet. Do not assume the lowest puddle identifies the entry point.

Make a cabin map that another person can read

Sketch the floor plan with the door at the bottom and label left, right, front and rear. Mark the first observed wet location, visible marks higher up and any nearby fitting. Put a photo number beside each mark. Use the same orientation in later photographs so “left corner” does not change with the photographer.

Take an overview before a close view where access is safe. Note when the rain occurred, when the water was discovered and whether the cabin had been used or cleaned since. Separate what you saw from what someone else reported. Do not conduct a hose test or recreate the event by soaking the cabin.

Keep rain entry and condensation as open possibilities

The supplied Cube 2 troubleshooting table lists rain or condensation as possible causes of water marks. It does not identify the cause of a particular owner’s mark from appearance alone. Label the event “water observed after rain” until assessed, rather than “roof leak confirmed”. ^[1]

Add a simple observation column: active droplet, damp patch, dry stain or pooled water. Record whether each was seen at discovery or only later. This prevents a later dry photograph from being mistaken for evidence that the cabin was never wet. A changed condition should be logged, not explained away.

Inspect only what is safely visible

The Cube 2 maintenance schedule calls for checking external silicone at front and rear panel-to-stave joins, roof joins and exposed weather seals monthly and after heavy rain. Use this to choose ground-level photo subjects. It is not permission to climb on the roof or replace sealant without establishing the actual repair scope. ^[2]

If electrical components appear damaged, the Cube 2 manual says not to operate. Keep any concern about wet electrical equipment separate from the cosmetic timber record and obtain electrical assessment rather than heating the sauna as a drying test. ^[3]

Send a repair question, not a proposed cure

A useful enquiry is: “Please assess photos A to D against the supplied assembly details. What is the likely route, what inspection is needed, and what repair and follow-up check do you approve?” Include the installation date and any previous sealing work or roof changes. This gives support a route to a defined decision.

Avoid starting with “which sealant should I buy?” A material name does not establish where it belongs, whether preparation is required or whether the apparent entry location is correct. Have the proposed repair location and method confirmed before applying sealant. Preserve the original evidence before any authorised change.

Example: a mark beside the front panel

Suppose a dry stain is found beside the doorway after overnight rain. The map shows the stain, the nearby exterior join and the discovery time. It also records that nobody observed dripping. A reviewer can then request the next relevant view or inspection; the record does not falsely turn a dry stain into proof of a failed roof.

After an approved repair, add the work date and the agreed way to monitor it. Keep later observations linked to the same map. The result is a traceable water-ingress case rather than a growing collection of unrelated close-up photographs.

Your practical checklist

Draw an oriented cabin map.
Distinguish active water from old dry marks.
Record rain, use and cleaning in the same timeline.
Photograph accessible external joins without climbing.
Keep original evidence and the approved repair record together.

Can a photo prove whether a mark is condensation?

Not by itself. The Cube 2 troubleshooting table allows rain or condensation as possible causes; record the circumstances instead of asserting a diagnosis. ^[1]

Should I apply silicone wherever the timber looks wet?

This guide gives no sealant repair instruction. Establish the entry route and approved repair scope first.
