Ownership

    Does a wet room affect your home insurance or resale value?

    A wet room is a structural change to your bathroom, which means both your insurer and a future buyer's surveyor will take an interest in how it was done.

    Does a wet room affect home insurance?

    A wet room should be declared to your home insurer as a bathroom alteration, and a correctly built, documented installation is normally covered under standard buildings insurance without a premium change. An undeclared or poorly documented conversion can complicate a future claim, particularly one involving water damage.

    01

    Telling your insurer

    Notify your insurer once the wet room is complete, in the same way you would for any bathroom renovation. Keep the tanking system documentation and any building warrant paperwork together with your policy documents — insurers can ask for this if a claim ever relates to water damage or the room's structure.

    02

    Does it increase your premium?

    A well-documented, professionally installed wet room does not typically increase a standard buildings insurance premium on its own. What can affect a premium is a poorly documented DIY conversion, which an insurer may treat as an unquantified risk if a claim arises.

    03

    Resale value

    A well-built wet room is generally a neutral-to-positive factor for resale, and a genuinely positive one where the property appeals to buyers needing level access. It's rarely, on its own, a reason a buyer rejects a property, provided it doesn't remove the household's only bath where that matters to the local buyer profile.

    What surveyors look for

    A mortgage valuation surveyor checks for visible signs of damp or poor workmanship rather than assessing the tanking directly, since that's not visible without lifting tiles. Documentation — the tanking system used, the building warrant position, and a workmanship guarantee — reassures a surveyor and a buyer's solicitor far more than the finish alone.

    Missing building warrant paperwork for work that needed one is a more common conveyancing snag than the wet room itself — see our guide to building warrants in Scotland.

    Common questions

    Frequently asked

    Consider your local buyer profile. In a one-bathroom property, removing the only bath can narrow appeal to some buyers, particularly families; in a property with a second bathroom, it matters far less.

    Where the work required a warrant, a missing completion certificate can delay a sale at the conveyancing stage, even if the work itself is sound. Confirm the position on our building warrant guide before work starts, not after.

    It widens appeal to buyers needing level access and is generally neutral to others, since a level-access threshold benefits anyone including families with prams or reduced mobility.
