Garden Sauna and Insurance: What to Check Before You Buy

These are questions that usually only come up after the purchase, but they should be settled beforehand. A lot depends on one decision: whether the sauna gets a foundation. This is general guidance; your insurer and, where relevant, your accountant decide your specific case.

Insurance: do not just assume

Buildings and home insurance policies often include outbuildings in the garden, but not always and not automatically.

A sauna with a wood stove is a structure with a fire in it, and insurers treat it separately for that reason. Sometimes it is excluded from the basic cover.

The simplest thing is to ask directly: is a garden sauna with a wood stove covered, up to what value, and does the premium change? One phone call.

What to tell your insurer

That the sauna exists, especially if its value is above the limit for outbuildings or garden items in your policy.

That it has a wood stove. If you do not mention it, that can be a reason to refuse a claim after a fire, and fire is exactly the case where sauna insurance really counts.

The replacement value rather than the purchase price, if your policy distinguishes between them.

Liability towards neighbours

If a spark from the chimney causes damage next door, you are liable. A spark guard on the chimney costs little and in wooded areas is part of the essential equipment, not an extra.

Check whether your personal liability cover includes something like this. It usually does, but the scope can differ.

Tax and rates, briefly

Whether an outbuilding matters for local property taxes or rates depends on the individual case. A sauna without a foundation that can be moved as a whole is the simpler case.

With a poured concrete foundation and fixed connections, ask your local authority or accountant if in doubt, before rather than at some later reassessment of the property.

Renting it out changes the rules

If the sauna is to run for guests, in a holiday flat, a holiday let or as part of a mobile sauna hire business, private insurance is usually not enough.

You generally need business insurance with third-party liability cover. Tell the insurer openly what the sauna is used for.

A practical order of play

First decide whether there will be a foundation. That one decision affects all the other topics at once.

Then one phone call to your insurer.

With a foundation, one question to your accountant or local authority.

Together that is a quarter of an hour, and the subject is settled for years.
