How to fix 50mm lip between bathroom and timber lounge floor?

[mzlink]

Hi, I’ve just had my bathroom rendered Ive been left with a 50mm lip (drop) between the bathroom door frame and lounge room floor. I was quite upset but told this was required. I’d like to know how I can make this less of a trip hazard. I’ve been looking a quad moldings but none are 50mm that I can find. I’m thinking I may be able to glue one ontop of the other to get the height required - would this work? Open to all suggestions

thanks in advance

Hi @mzlink,

Thank you for sharing the solution you came up with.

I hope you're happy with the quad. I think it looks fantastic.
