Your bathroom should be installed by a plumber with knowledge of these rules to ensure you meet waste drainage requirements. There are also concerns surrounding the wastage of water and contamination that need to be addressed.

Ventilation

Bathroom ventilation is especially important in a bathroom due to the chances of condensation and the resulting mould. Most new bathrooms will require an extractor fan or a good sized window.

It is important that you use a qualified electrician for all installations in bathrooms and that the work is checked under an approved scheme, such as that run by the NICEIC. One rule involves the use of pull switches or switches located outside the bathroom.

Structure

Your new loft conversion is likely to involve the strengthening of the floor, but this may need to be even more sturdy if you intend to have a bath in your loft bathroom.
