Revenue from brands targeting 18 - 34 year old females in bars, nightclubs and shopping centres grew from £3.4 million in 2005 to £4.75 million last year.
Admedia claimed the ad format reaches more than five million females in the target demographic within a four week period.
Consumer brands such as Nivea, Pretty Polly, Unilever Personal Care, Max Factor and Sloggi are among those that have invested significantly in washrooms over the last year.
The company predicted equal growth this year to more than £7 million and said many brands were requesting repeat activity after successful campaigns.
