Has anyone laid Maria Harvey patterned flooring in tenement gallery bathroom?

I have not used this specific one, but I use similar quite often. I have found this kind of flooring to be very good and easy to lay, clean, etc. I would advise that you make sure that the floor is perfectly flat as it has a habit of showing anything more textured that wood grain. So I use thin play and waterproof it with Thompson's Water Seal, then lay this on top. Just make sure that the one you choose is non slip regardless of where you fit it.
