5. Check For Leaks

A constant but small leak can lead to untold damage if left unchecked. Ensure all pipe-work is bone dry (especially around connections). Have a close look around shower tray and bathtub to make sure that all of seals are still intact. Mould growing in silicone seal itself usually (but not always) indicates that moisture has got behind seal.

6. Install Surfaces That Do Not Harbour Mould

Ceramic tiles are commonplace in most bathrooms but are cold to touch, attracting condensation. Although tiles are waterproof grout used between joints can retain moisture and lead to mould growth.

Plasterboard (drywall) ceilings and walls can suck in moisture if they come into contact with water, enabling mould to grow even if surface looks dry.

A modern alternative to these products is bathroom cladding. This is a form of waterproof wall panelling that is warm to touch, so condensation will not form on it. Bathroom cladding uses no grout - each panel slots into next using a tongue and groove system - so there is nowhere to harbour moisture.

Following these steps should lead to a mould free bathroom.
