A VIRAL video with over 14 million views shows a shocked homeowner discovering a secret shower and mirror which had been walled off in her bathroom.

Hannah Otto, from Twyford, was renovating her bathroom when she noticed the tiles around her already existing shower start to move.

Upon investigation, she peeled away layers of the wall to find a completely separate shower and a mirror.

The 32-year-old runs 'The Otto House' TikTok account, which she has used to document her renovation progress since purchasing the house in 2020.

In the video, she removes a wooden panel to find "A whole shower just casually sitting behind our actual shower."

After looking behind a hole in the tile, she finds a mirror behind the secret shower.

She said: "I've got a mirror and tile behind a shower and tile, behind what was a shower and tile."

Her video has received thousands of comments, with one saying: "Di... Did they just slap a new layer on every time it leaked?"

Another user remarked: "It's like inception but for bathrooms."

While a different comment said: "Rumour has it she's still there finding showers."
