Wet room

Wet room -1336165 640.jpg

Approved document M, Volume 1: Dwellings (2015 edition incorporating 2016 amendments), defines a ‘wet room’ as a:

WC or bathroom compartment with tanking and drainage laid to fall to a connected gulley capable of draining the floor area when used as a shower.’

However, the Home Quality Mark (HQM) defines a wet room as:

'...a room used for domestic activities (such as cooking, clothes washing and bathing) which give rise to significant production of airborne moisture, e.g. a kitchen, utility room or bathroom.' NB For the purposes of HQM, drying space is also regarded as a wet room. Ref Home Quality Mark One, Technical Manual SD239, England, Scotland & Wales, published by BRE in 2018.
